8IR :  The  volume  which  I  have  now  the  honor  to  submit,  has  heen  prepared  in  accordance  with 
your  general  instructions,  given  at  the  time  you  were  pleased  to  intrust  me  with  the  immediate 
oharge  of  that  portiijn  of  the  huainesa  of  this  ofiice  which  relates  to  meteorology,  and  to  the 
statistics  of  sickness  and  Mortality  in  the  army. 

The  meteorological  records  of  this  bureau  prior  to  1842  having  already  been  published,  there 
remained  for  examination  those  only  which  had  accumulated  since  January,  1843  ;  at  which  time 
the  new  and  improved  system  of  observations  went  into  operation.  These  proved  so  abundant  that 
a  division  seemed  necessary  for  the  purposes  of  publication,  and  it  was  determined  to  confine  the 
present  work  to  the  observations  of  the  thermometer,  direction  and  force  of  winds,  clearness  of  sky, 
and  fall  of  rain  and  enow.  To  these  were  subseq^uently  added  a  series  of  consolidated  temperature 
and  rain  tables ;  the  former  representing  the  results  of  all  the  records  of  thermometrical  observa- 
tions since  1822,  and  the  latter  exhibiting  all  measurements  of  rain  since  1836, 

In  addition  to  the  labor  involved  in  the  construction  of  the  series  of  consolidated  temperature 
and  rain  tables,  and  the  investigations  necessary  for  determining  the  precise  geographical  position 
and  altitude  above  the  sea  of  the  several  stations,  the  preparation  of  this  work  has  required  the 
careful  and  minute  examination  and  computation  of  over  eight  thousand  monthly  registers,  con- 
taining in  the  aggregate  nearly  four  millions  of  observations.  In  the  monthly  tables,  each  lino 
represents  the  results  of  480  observations,  exclusive  of  those  on  the  fall  of  rain  and  snow ;  and 
gives,  in  addition  thereto,  the  range  of  the  thermometer,  the  number  of  fair  and  cloudy  days,  and 
days  of  rain  and  snow. 

The  means  of  observations  of  the  thermometer,  as  given  in  this  Register,  have  been  deduced  from 
the  four  daily  observations,  instead  of  the  two  at  sunrise  and  3  p.  m.,  as  originally  directed  by  the 
department ;  it  having  been  satisfactorily  shown  by  the  data  in  this  office,  that  the  result  thus 
obtained  more  nearly  approximated  the  true  daily  mean  as  determined  by  hourly  observations. 

The  thermometers  used  by  the  medical  officers  during  the  last  twelve  years,  were  made  to  order 
by  Mr,  George  Tagliabue,  philosophical  instrument  maker.  New  York,  after  standard  No,  6  of  the 


National  Observatory. 
In  examining  the  consoli 
furnished  were  not  so  uui 


ith  which  they  were  compared  at  four  points,  viz:  32°,  52°,  72°,  and  92°, 
dated  temperature  tables,  the  fact  that  previous  to  1843  the  thermometers 
formly  or  carefully  constructed,  should  be  considered.

The  formula  adopted  for  expressing  the  "aumber  of  observations  and  sum  of  force  of  winda," 
and  "mean  clearness  of  sky,"  are  explained  in  the  " directions  for  taking  meteorological  ohserva- 
tions,"  as  given  in  the  introduction  to  this  volume.  The  number  of  days  fair  and  cloudy  have  been 
determined  from  the  original  daily  observations ;  those  in  which  the  aggregate  of  the  four  daily 
observations  as  expressed  in  figures  exceeded  20,  being  recorded  a,s  fair,  and  those  less  than  that 
number,  as  cloudy.     The  number  of  days  on  which  it  rained  or  snowed  are  recorded  separately. 

No  effort  has  been  spared  to  make  the  work  as  free  from  error  as  possible.  The  arrangement 
of  the  stations  in  geographical  districts  having  similar  climatological  features  has  facilitated  the 
detection  of  erroneous  computations.  The  annual  summaries  served  to  prove  the  correctness  of  the 
monthly  tables  ;  and  the  consolidate-d  tables  afforded  a  third  point  of  comparison,  so  far  as  regards 
the  temperature  and  rain  observations.  All  observations  have  been  given  as  originally  recorded  ; 
but  in   cases  where   there  were   good   reasons   for  doubting   their  accuracy,    the   doubt  has   been 


The  general  arrangement  of  the  tables,  and  the  grouping  of  the  stations  in  climatological  dis- 
tricts, were  adopted  principally  at  the  suggestion  of  Lorin  Blodget,  Esq.,  who  has  been  associated 
with  me  in  the  preparation  of  the  entire  work,  The  isothermal  and  rain  charts  were  designed  and 
prepared  exclusively  by  him,  and  he  is  entitled  to  whatever  of  scientilic  value  may  attach  to  them, 
and  to  the  accompanying  report  explanatory  of  the  principles  upon  which  they  were  constructed,  and 
of  the  results  which  they  exhibit. 

The  map  which  serves  as  a  basis  for  these  charts  has  been  most  carefully  drawn,  under  my 
direction.  Its  coast  outline  was  determined  by  reference  to  the  latest  published  charts  of  the  United 
States  Goast  Survey ;  the  topography  of  the  interior,  west  of  the  Mississippi  river,  is  given  from  the 
reports  and  maps  of  recent  explorations  for  a  route  for  a  railroad  to  the  Pacific  ;  and  all  the  military 
posts  at  which  observations  have  been  taken,  are  located  with  great  exactness. 

In  conclusion,  I  beg  permission  to  state  that  I  have  shared  in  the  laborious  computations  of  this 
work,  to  the  fullest  extent  which  my  more  imperative  duties  to  the  sick  would  permit ;  and  that  every 
portion  thereof  has  received  my  careful  examination  and  supervision. 

Very  respectfully,  your  most  obedient  servant,

INTRODUCTION 


Previous  to  the  year  1818  we  possess  no  records  of  meteorological  observations  taken  in  the 
United  States  on  an  extensive  scale.  In  that  year  Congress,  acting  upon  the  recommendation  of  the 
Hon.  John  C.  Calhoun,  then  Secretary  of  War,  created  the  oBice  of  Surgeon  General  of  the  Army, 
to  which  Hospital  Surgeon  Joseph  Lovell  was  immediately  appointed.  The  Medical  Department  was 
not,  however,  fully  organized  upon  its  present  hasis  until  the  year  1821, 

Soon  after  his  appointment,  Surgeon  General  Lovell  submitted  to  the  Secretary  of  War  for 
approval,  a  system  of  regulations  for  the  government  of  the  Medical  Department.  Therein,  among 
other  duties,  the  surgeon  was  required  "to  keep  a  diary  of  the  weather,  and  to  note  everything  of 
importance  relating  to  the  medical  topography  of  his  station,  the  climate,  diseases  prevalent  in  the 
vicinity,"  &c,,  and  transmit  it  cLuarterly  to  the  Medical  Bureau  at  Washington.  The  earliest  regis- 
ters thus  forwarded  and  on  file  in  the  Surgeon  G-eneral's  Office  are  dated  January,  1819. 

Thus  did  the  Medical  Department,  at  its  very  origin  as  a  distinct  branch  of  the  staff  of  the  army^ 
enter  upon  a  system  of  meteorological  observations,  in  which  it  has  since  been  followed  by  the  States 
of  New  York,  Pennsylvania,  and  Ohio,  and  also  by  the  Smithsonian  Institution.  New  York  com- 
menced in  1825,  Pennsylvania  in  1836,  Ohio  in  1842,  and  the  Smithsonian  Institution  in  1849. 

The  only  instruments  used  at  first  were  a  thermometer  and  vane ;  and  the  observations  were 
confined  to  the  temperature  of  the  air  and  the  course  of  the  winds,  with  general  notices  of  the  weather. 
The  thermometer  was  noted  at  T  A.  M.,  2  r.  M.,  and  9  p.  m.,  and  the  winds  and  weather  were  observed 
morning,  noon,  and  evening.  Early  in  the  year  1836  a  rain  gauge  was  furnished  to  each  post,  and  the 
daily  fall  of  rain  recorded  in  the  register.  No  change  was  made  in  the  hours  of  observation  until 
January,  1841,  when  "sunrise"  was  substituted  for  T  A.  M. ;  and  in  1842^  the  number  of  daily  obser- 
vations were  increased  to  four,  and  the  hours  adopted  were  "  sunrise,  2  p.  M.,  sunset,  and  9  p.  m." 

The  results  of  the  observations  for  1820  and  1821  were  published  at  the  end  of  each  year.  Those 
of  subsequent  observations  have  been  published  in  a  series  of  army  meteorological  registers,  of  which 
the  first  volume,  embracing  the  years  from  1822  to  1825,  inclusive,  was  issued  by  Surgeon  General 
Lovell  in  1826.  The  second  and  third  volumes  of  the  series,  comprising  respectively  the  years  from 
1826  to  1830,  and  from  1831  to  1842,  inclusive,  were  prepared  and  published,  the  former  in  1840,  and 
the  latter  in  1851,  under  the  direction  of  the  present  Surgeon  General,  Doctor  Thomas  Lawson,  who 
i  to  that  office  upon  the  death  of  Doctor  Lovell,  in  October,  1836.

VI  INTRODUCTION. 

Prompted  by  a  desire  to  make  the  labors  of  the  medical  officers  in  the  field  of  meteorology  more 
practically  ueefiil,  in  elucidating  and  defining  the  relations  of  atmospheric  vieieaitudcs  and  phenomena 
in  the  causation  and  development  of  disease  ;  and  at  the  same  time  to  render  them  available  for  the 
purposes  of  science  in  general ;  the  Surgeon  General  in  1840  and  1841  applied  to  Congress  for  an 
appropriation  to  enable  him  to  extend  the  system,  and  render  it  more  complete.  "With  the  funds 
appropriated  for  this  purpose,  a  number  of  barometers  and  hygrometers  were  imported  from  Europe, 
and  distributed  to  certain  selected  stations  for  experiment. 

In  May,  1842,  the  Army  Medical  Board,  then  in  session  at  Philadelphia,  was  instructed  to 
prepare  practical  directions  for  taking  meteorological  observations  in  an  extended  form.  "The 
Board,  consisting  of  Surgeons  Thomas  G-.  Mower  and  Henry  A.  Stinnecke,  and  Assistant  Surgeon  John 
M,  Cuyler,  diligently  sought  information  from  all  authentic  sources  within  their  reach,  and  at  length 
drew  up  a  set  of  directions,  which  were  submitted  for  the  approval  of  the  Surgeon  G-eneral,  and  Secre- 
tary of  War,  and  finally  adopted  for  the  government  of  the  medical  officers  in  their  meteorological 
observations.  In  preparing  these  directions  the  Board  received  valuable  aid  from  Professor  A,  D. 
Bache,  Professor  Bartlett,  of  the  United  States  Military  Academy,  J.  P.  Espy,  Esc|_.,  and  from  the 
instructions  of  the  Eegents  of  the  University  of  New  York,  of  the  Franklin  Institute,  at  Philadelphia, 
and  of  the  Koyal  Society,  London." 

The  system  thus  extended,  went  into  operation  on  the  first  day  of  January,  1843.  It  embraced  four 
observations  daily  of  the  barometer,  attached  thermometer,  thermometer  detached,  clearness  of  the 
sky,  direction  and  force  of  the  wind,  and  the  direction  and  velocity  of  the  clouds.  To  these  were 
added  two  daily  observations  on  the  wet-bulb  thermometer,  and  the  measurement  of  rain  and  snow. 
Hourly  observations  of  the  barometer,  thermometer,  &c.,  were  also  directed  to  be  taken  for  twenty- 
four  hours  at  the  equinoxes  and  solstices. 

The  following  "  directions,"  drawn  up  by  the  Board  and  adopted  by  the  Department,  were  pub- 
lished for  the  use  of  the  officers  of  the  medical  staff,  who  were  required  to  obey  them  in  all  respects 
with  the  utmost  strictness  and  regularity,  and  were  held  officially  responsible  for  the  accuracy  of  their 
observations. 


DIRECTIONS  FOR  TAKING  METEOROLOGICAL  OBSERVATIONS. 

OnSEavAtiONS  of  the  barometer,  with  its  attached  thermometer,  of  the  thermometer,  (detached,) 
the  clearness  of  the  sky,  the  direction  and  force  of  the  wind,  and  the  direction  and  velocity  of  the 
clouds,  will  be  made  at  a  little  before  sunrise,  9  A.  M.,  3  p.  M.,  and  9  p.  M. 

Observations  6f  the  wet-bulb  thermometer  are  to  be  taken  at  a  little  before  sunrise,  and  at  3  p,  m. 

At  every  fall  of  rain,  snow,  hail,  or  sleet,  the  time  of  its  commencement  and  end  will  be 
recorded,  and  the  quantity  which  fell,  as  indicated  by  the  rain-gauge. 

Each  of  the  above  observations  will  be  registered,  as  soon  as  made,  in  its  appropriate  column. 
Shotild,  however,  an  observation  be  from  necessity  omitted  at  any  of  the  regular  periods,  it  is  enjoined 
that  a  blank  be  left  on  the  register  in  the  place  where  the  omitted  observation  should  have  been 
recorded. 

The  "  daily  mean"  of  the  thermometer  (detached)  is  to  be  found  by  adding  together  the  obser- 
vations at  sunrise  and  3  p.  M.,  and  halving  the  sura.

INTRODUCTION.  VII 

At  the  end  of  the  month  add  up  each  column  of  figures  on  the  register,  under  the  heads  of 
"  barometer,"  "  thermometer  attached,"  "  thermometer  detached,"  "  clearness  of  the  shy,"  and  "wet- 
hdb,"  and  divide  tlie  sum  hj  the  number  of  days  on  which  observations  were  made.  The  quotient 
will  be  placed  at  the  foot  of  each  column,  upon  the  line  marked  "  montTily  mean." 

The  "  quantity  of  rain"  will  also  he  added  up,  and.  the  sum  placed  at  the  foot  of  the  proper 
column. 

In  all  entries  on  the  register,  fractions  will  be  expressed  in  decimaU. 

BAROMETER. 
The  instrument  adopted  hy  the  Department  is  the  syphon  haromtster  of  Biinten."" 
THERMOMETER  (DETACHED.) 

The  thermometer  will  be  placed  in  a  situation  having  a  free  circulation  of  air,  not  exposed  to 
the  direct  or  reflected  rays  of  the  sun,  and  sheltered  from  rain.  Its  situation  should  be  remote 
from  massy  walls,  which  slowly  imbih'e  or  part  with  caloric.  In  mating  observations  avoid  breathing 
on  the  instrument,  or  touching  it ;  and  at  night  manage  your  lamp  so  as  not  to  cause  a  rise  of  the 
mercury  by  its  heat. 

CLEARNESS  OF  THE  SKY. 

The  amount  of  clear  sky,  at  the  hours  of  observation,  will  be  designated  by  the  figures  0,  1,  2, 
3,  4,  5,  6,  7,  8,  9,  and  10;  0  signifying  no  clear  sky;  1,  a  very  small  portion  of  clear  sky;  and  so  on 
to  10,  which  indicates  the  entire  absence  of  clouds,  or  hasie, 

WIKD. 

The  direction  and  estimated  force  of  the  wind  will  be  registered  together. 

The  direction  will  be  expressed,  as  is  customary,  hy  the  letters  which  denote  the  points  of  the 
compass,  as  W.,  S.W.,  S.S.W.,  &e.  The  force  of  the  wind  will  be  expressed  hy  figures  from  0  to 
10,  thus: 

0  will  signify  a  calm ; 

1  "         "       a  barely  perceptible  hi'ppze ; 
H     "         "       a  gentle  breeze ; 

■!  "  "       a  moderate  breeze ; 

4  "  "a  brisk  breeze  ; 

5  "  "       a  strong  wind; 

6  "  "       a  very  strong  wind ; 
T  '  ^  "       a  storm ; 

8  "         "a  great  storm  ; 

9  "         "a  hurricane;

Vni  INTRODUCTION. 

CLOUDS. 
As  several  stratii  or  euvrents  of  clouds  often  exist  at  different  heights,  the  direction  and  velocity 
of  motion  of  the  lowest  stratum  only  will  he  registered  under  the  head  of  clouds,  using  the  same  ex- 
pressions as  in  registering  the  wind.  Thus,  shoidd  the  clouds  move  hrishly  from  the  8.W.,  the 
expression  would  be  S.W.  4,  the  letters  denoting  the  direction,  and  the  figure  the  velocity  of  the 
motion. 

WET-BULB. 

The  hygrometric  condition  of  the  atmoephere  may  be  indirectly  determined  by  ascertaining  the 
degree  of  refrigeration  produced  hy  the  evaporation  of  water  in  the  open  air.  The  most  easy  method 
of  finding  this  is  to  wet  the  hulb  of  a  thermometer  covered  round  with  fine  gauKe,  and  swing  the 
instrument  in  the  open  air,  in  the  shade,  until  the  mercury  sinks  as  low  aa  it  will, 

The  current  of  air  upon  the  wet-bulh  should  be  kept  up  (hy  swinging)  aa  long  as  the  mercury 
continues  to  descend  in  the  tube  of  the  instrrunent,  and  for  a  few  minutes  after  it  becomes  stationary, 
in  order  to  insure  the  full  effect  of  the  evaporation,  and  the  lowest  degree  to  which  the  mercury  can 
be  forced  to  descend  by  this  process,  will  constitute  the  observation  rccLuired,  and,  as  euch,  it  will  be 
recorded  on  the  Register,  in  the  column  headed  "Wet-Bulb." 

The  water  used  to  wet  the  bulb  of  the  Thermometer  should  be  as  nearly  as  possible  at  the  same 
temperature  as  the  air,  at  the  time  of  taking  the  observation.  It  should  not  be  poured  upon  the  bulb 
of  the  thermometer,  but  applied  with  a  bit  of  sponge,  a  fine  brush,  or  any  similar  substance,  and  when 
the  temperature  is  near,  or  below  the  freezing  point,  care  should  be  taken  simply  to  moisten  the  gauze. 

EAIN.- 

The  instrument  used  to  measure  the  quantity  of  rain  which  falls  is  the  conical  rain  gauge, 
It  will  be  kept  remote  from  all  elevated  structures,  at  a  distance  at  least  equal  to  their  height,  and 
still  further  off,  where  it  can  be  conveniently  done.  It  is  to  he  suspended  in  a  circular  opening  made 
in  a  board,  which  is  to  be  fixed  to  a  post,  eight  feet  from  the  ground ;  the  opening  to  he  five  inches  in 
diameter,  and  bevelled  so  as  to  fit  the  side  of  the  gauge,  into  which  the  cap  is  to  be  fixed,  base 
downwards,  to  prevent  evaporation.  The  measurement  is  made  by  putting  down  perpendicularly  to 
the  bottom  of  the  gauge  the  measuring  stick,  and  applying  it,  from  its  point  to  the  water  mark,  on 
the  scale,  which  will  express  the  quantity  in  inches,  or  their  decimals.  The  graduation  of  the  scale 
is  by  hundredths  of  an  inch  for  the  first  three  tenths  of  an  inch,  and  above  that  by  tenths  and  half 
tenths.  Parts  of  degrees  will  be  measured  by  the  eye,  and  set  down  in  decimals.  If  a  rain  continue 
for  any  length  of  time,  the  cLuantity  in  the  gauge  will  be  measured  at  suitable  intervals,  before  the 
water  rises  liigh  in  it,  and  the  measurements  summed  up  at  the  close. 

In  freezing  weather,  when  the  rain  gauge  cannot  be  used  out  of  doors,  it  will  be  taken  into  the 
room,  and  a  tin  vessel  will  be  substituted  for  receiving  the  snow,  rain,  or  sleet,  that  may  then  fall. 
This  vessel  must  have  its  opening  exactly  equal  to  that  of  the  rain  gauge,  and  widen  downwards  to  a 
sufficient  depth  with  a  considerable  slope.  It  should  be  placed  where  nothing  can  obstruct  the 
descending  snow  from  entering,  and  where  no  drift  snow  can  be  blown  into  it.  During  a  continued 
snow  storm,  the  snow  may  be  occasionally  pressed  down.  The  contents  of  the  vessel  must  he  melted 
by  placing  it  near  the  fire,  with  a  cover  to  prevent  evaporation,  and  the  water  produced  poured  into 
the  gauge  to  ascertain  its  quantity,  which  must  then  be  entered  on  the  register.

Under  this  head  may  be  noted  all  remarkable  phenoinenaj  especially  sudden  and  simultaneous*' 
changes  of  wind  and  temperature  ;  theu-  effect  on  tlio  barometflr  ;  the  moment  of  greatest  depression 
of  the  barometer  in  the  passage  of  storms  ;  currents  of  clouds  moving  in  different  directions,  and  at 
different  heights  ;  the  rise  and  fall  of  rivers  and  lakes  ;  remarkable  tides  ;  the  opening  and  closing  of 
navigable  waters  ;  the  last  killing  frost  that  occurs  in  spring,  and  the  first  in  axituum,  as  shown  by 
their  effects  on  the  tender  buds,  leaves,  and  germs  of  fruit  trees,  &c.  ;  the  commcnecmcnt  and  progress 
of  vegetation  ;  the  iirst  appearance  and  departure  of  birds  of  passage  ;  thunderstorms,  near  or  remote; 
silent  lightning,  with  its  direction  and  elevation  above  the  horizon  ;  fiills  of  hail,  enow,  and  sleet; 
fogs ;  white  or  hoar  frost,  &c. 

Always  examine  the  heavens  at  the  latest  observation,  whether  there  be  any  Aurora,  or  shooting 
stars  ;  and  especially  about  the  10th  of  August,  and  12th  and  13th  of  N'ovember,  see  -whether  there 
be  any  great  number  of  luminous  meteors  visible,  stating  the  number  observed  in  an  hour,  or  at  least 
in  a  quarter  of  an  hour.  In  case  of  great  fires  occurring  in  clear,  calm,  dry  weather,  with  a  bigb  dew 
point,  observe  whether  clouds  form  over  the  fire,  and  describe  the  phenomena. 

SrECIAL  OBSERVATIONS. 

Hourly  observations  of  the  barometer  will  be  taken  for  24  hours,  at  the  equinoxes  and  solstices,  to 
correspond  with  those  already  instituted  at  numerous  points  of  Europe  and  America,  at  the  suggestion 
of  Sir  John  Herschel.  The  days  fixed  upon  for  these  observations  are  the  21st  of  March,  June, 
September,  and  December.  But  should  any  one  of  these  21st  days  fall  on  Sunday,  tlien  the  observa- 
tions will  be  deferred  till  the  next  day,  the  22d. 

The  observations  at  each  station  will  commence  at  6  o'clock  a.  ji.  of  the  appointed  days,  and  be 
continued  at  the  beginning  of  each  bonr  till  G  ,\,  i^i.  of  the  following  days,  care  being  taken  to  obtain 
the  coiTcct  time. 

The  exact  maximum  and  minimum  of  temperature  of  the  24  hours  should  be  recorded,  under  the 
head  of  "  Remarks,"  at  the  precise  houi'  and  minute  at  which  they  occur. 

The  value  of  tliese  hourly  observations  will  bo  greatly  enhanced,  if  tbey  be  extended  to  all  the 
objects  embraced  in  the  daily  register.  If  there  be  a  storm  about  those  times,  hourly  obseiwations  of 
all  the  phenomena,  from  the  beginning  to  the  end  of  the  storm,  will  also  be  valuable. 

All  special  obsei-vations  will  be  recorded  separately. 

Connected  with  meteorology  are  many  interesting  subjects  of  inquiry,  which  can  only  be  elucidated 

.   by  wide-spread,  simultaneous  observations.     TIic  medical  officers  of  the  army  are  therefore  confidently 

invited  to  co-operate  in  the  collection  of  data  tending  to  advance  the  interei^te  of  sciouce.     For  the 

accuracy  of  onr  observations,  (quoted  as  tbey  will  be  both  at  home  and  abroad,)  it  is  hardly  necessary 

to  say,  the  reputation  of  the  department  is  pledged.

X  INTRODUCTION. 

The  ai'my  system  of  meteorological  observations  was  intended  to  be  primarily  subservient  to  tlie 
advancement  of  medical  science,  and  secondarily  to  that  of  meteorology  as  a  distinct  branch  of  physics. 
The  relations  of  atmospheric  phenomena  to  disease  have  been  to  some  extent  considered  in  a  "Statis- 
tical Report  on  the  Sickness  and  Mortality  in  the  Army  of  the  United  States,"  prepared  under  the 
direction  of  the  Surgeon  G-eneral,  and  published  in  1840  ;  and  it  is  proposed  still  further  to  discuss 
those  relations  in  a  similar  report  now  in  course  of  preparation.  The  Department  has  heretofore, 
howcTer,  made  no  attempt  to  deduce  general  scientific  results  from  the  mass  of  material  it  has  accumu- 
lated. Its  position  in  regard  to  the  science  of  meteorology  was  that  of  a  collector  of  facts  carefully 
observed,  and  the  results  of  the  labors  of  the  medical  officers  have  been  from  time  to  time  given  to 
the  public,  in  the  hope  that,  in  the  hands  of  those  who  were  specially  devoted  to  such  investigations, 
they  would  aid  in  establishing  or  refuting  some  of  the  interesting  theories  of  this  science,  and,  taken 
in  connection  with  other  data,  perhaps  lead  to  the  discovery  of  definite  laws. 

Within  a  few  years  past  some  portions  of  the  army  records  hare  been  used  in  connection  with 
certain  scientific  inquiries  and  investigations;  but  no  effort  has  been  made  to  deduce  therefrom  general 
results.  It  was  to  such  results  that  the  medical  ofBccrs  looked  forward  as  the  reward  of  their  labors. 
For  thirty-six  ycara  they  had  patiently  observed  and  recorded  facts  in  meteorology.  In  that  time  the 
army  stations  had  gradually  extended  from  the  Atlantic  to  the  Pacific  coast,  and  from  the  47th 
parallel  of  north  latitude,  to  the  banks  of  the  Rio  Grande.  The  establishment  of  a  new  military  post 
and  the  commencement  of  observations  thereat,  were  almost  uniformly  simultaneous  ;  and  the  number 
of  registers  forwarded  from  the  cities  of  Mexico  during  their  temporary  occupation  by  the  troops  of 
the  United  States  attest  that  the  excitements  of  war  were  not  sufSciont  to  render  the  medical  officers 
forgetful  of  the  interests  of  this  science. 

The  present  volume,  the  fourth  in  the  series  of  registers  issued  from  the  Surgeon  General's  Office, 
has  been  prepared  with  a  view  to  meet,  in  part  at  least,  these  just  expectations.  It  contains  the  results 
of  the  observations  of  the  thermometer,  direction  and  force  of  winds,  clearness  of  sky,  and  fall  of  rain 
and  snow,  during  a  period  of  twelve  years — from  the  first  day  of  January,  1843,  to  January,  1855 — 
arranged  in  monthly  tables  and  annual  summaries.  To  these  have  been  added  consolidated  tempe- 
rature and  rain  tables  for  each  separate  station,  comprising  the  results  of  all  the  thermometric 
observations  made  by  medical  officers  since  1822,  and  of  all  measurements  of  rain  and  snow  since  the 
introduction  of  the  rain  gauge  in  1836. 

The  geographical  position  and  altitude  above  the  sea  of  each  station,  as  given  in  this  volume, 
have  been  determined  with  great  exactness.  This,  together  with  the  brief  topographical  description 
of  each  military  post,  materially  enhances  the  value  of  the  work  as  a  book  of  reference. 

The  feature  which  distinguishes  this  register  from  its  predecessors,  is  the  charts  of  distribution  of 
temperature  and  of  rain  with  which  it  is  illustrated,  and  which  have  been  prepared  exclusively  from 
data  in  the  Surgeon  General's  Office.  The  principles  upon  which  these  charts  have  been  constructed, 
and  the  general  results  they  are  intended  to  exhibit,  are  fully  explained  in  the  accompanying  report. 
It  was  intended  to  give  the  observations  on  the  ' '  direction'  and  velocity  of  the  clouds' '  in  this 
edition,  but  finding  that  they  could  not  be  included  without  a  material  modification  of  the  tables,  and 
a  great  increase  in  the  size  of  the  book,  the  idea  was  reluctantly  abandoned. 

The  system  of  "wet  bulb"  observations  adopt-ed  in  1843,  with  the  view  of  ascertaining  the 
relative  humidity  of  the  air,  was  discontimied  in  1849,  having  failed  to  give  satisfactory  results.

INTRODUCTION.  XI 

Tlio  directions  iveroj  to  wet  the  gausie-coveietl  bulb  of  a  thermometer,  and  to  "swing  the  iustrnment 
ill  the  open  air  in  the  shade  until  tlie  mercury  sinks  as  low  as  it  will."  The  time  reqviired  to  ensure 
the  full  effect  of  evaporation  by  this  process  varies  from  ten  minutes  to  half  an  hour,  according  to  the 
temperature  of  the  air.  The  instrument  was,  therefore,  not  adapted  to  the  military  service,  the  time 
required  for  a  single  observation  being  more  than  the  medical  officers  could  always  command.  To 
supply  this  deficiency  the  Department  is  now  distributing  to  the  military  stations  a  hygrometer, 
consisting  essentially  of  a  thermometer,  the  bulb  of  which  is  covered  with  floss  silk,  enclosed  in  a 
piece  of  thin  muslin,  the  ends  of  the  silk  sufficiently  long  to  dip  Into  water  contained  in  a  braes 
reservoir  secured  immediately  below  the  bulb.  In  the  top  of  this  reservoir  is  a  small  opening  to  admit 
the  silk,  and  to  the  front  is  attached  a  cylinder-  communicating  with  the  interior  by  a  small  hole. 
This  instrument  can  be  observed  with  the  same  ease  as  an  ordinary  thermometer,  the  directions  being 
to  keep  the  reservoir  supplied  with  rain  or  distilled  water,  and  in  freezing  weather,  when  the  bulb  is 
not  wet  by  capillary  absoption,  to  moisten  the  gauze  about  fifteen  or  twenty  minutes  before  the  time 
for  making  the  observation. 

Observations  on  the  barometer  and  attached  thermometer  have  been  made  at  fifty-one  stations  for 
various  periods  during  the  last  twelve  years  ;  these,  together  with  the  "  hourly  observations"  at  the 
equinoxes  and  solstices,  remain  on  file  in  the  Medical  Bureau,  and  will  afford  ample  material  for 
another  volume.

J/ole  to  the  TfinjMrndire  Snmmariesfor  1851. 

For  the  temperature  summai-ies  of  1350  and  1851  the  latitudes,  longitudes,  and  altitudes  of  tlie  posts  have  been  revised  aiid  cor- 
rected from  the  best  authorities.  Tlia  very  recent  estensJTO  surveys  of  the  interior  and  of  tlie  Ooast,  furnish  geographical  positions 
very  near  to  accuracy  lor  each  of  the  new  posts  of  the  interior  and  wBEtem  coaEt,  and  corieotiona  for  several  Bastem  elations.  Many 
of  these  determinations  are  Brat  ariilable  as  this  work  ia  passing  through  the  press. 

The  altitude,  \u  some  cases,  varies  in  successive  years  fiom  a  ohaii^'c  of  tlic  precise  position  iiL  which  the  obncrvations  arc  taken.

GEOGRAPHICAL  POSlTiOKS  01?  THE  MILITARY  POSTS, 


WITH   THEIR   LOCAf,    TOl'OGKAPHr  AKl)   ALTIT0DES   ABOVE    THE   SEA,  AND    THE  AUTHORITIES 
I'-nOM  WHICH  THEY  HAVE  BEEN  OBTAINED. 


In  the  summaries  for  each  year  the  geograpliical  positions  and  altitiides  have  been  given  i'rom 
the  heet  authorities  at  hand,  or  accessible  at  the  time;  yet,  the  discrepancy  of  authorities  in  many 
cases  is  so  great  that  changes  have  sometimes  been  made  -when  better  determinations  were  eubse- 
qnently  obtained.  The  research  iec[tiired  in  the  comparison  of  existing  authorities  ia  very  consider- 
able, and  in  the  western  portion  of  the  territory  the  positions  are  all  of  recent  determination.  Tho 
recent  surveys  have  greatly  modified  the  geography  of  many  portions  west  of  the  Mississippi,  and 
they  have  come  in  very  fortunately  to  establish  the  positions  of  tlie  military  posts  with  great  accuracy. 
In  the  summary  for  1854  all  these  corrections  are  introduced,  and  the  positions  there  given  may  be 
relied  upon  as  sufficiently  accurate  for  any  purpose  in  thia  connexion.  In  the  succeeding  consolidated 
tables,  where  the  results  for  each  post  are  given  for  successive  years,  the  corrected  latitude,  longitude, 
and  altitude,  will  be  found  for  each  post  at  which  observations  have  at  any  time  been  made. 

I'ractions  less  than  one  miuute  of  a  degree  are  neglected,  even  when  determined  astronomically, 
as  unnecessarily  precise  for  the  present  purpose.  Many  of  the  interior  and  western  posts  were  de- 
termined (juite  accurately  by  astronomical  observation. 

The  posts  of  the  Atlantic,  Pacific,  and  Grulf  coasts,  were,  in  nearly  every  case,  made  points  or 
bases  of  triangulation  in  the  surveys  of  the  coast,  and  their  positions  have  tlius  been  very  accurately 
determined. 

On  the  Northeast  boundary,  and  on  the  Mexican  boundary,  the  positions  have  been  determined 
with,  great  accuracy  in  the  boundary  sruveys. 

The  research  and  comparison  lias  been  made  as  thorough  at  the  last  as  appeared  necessary  for 
any  purpose  affecting  the  records  or  their  resi\lts,  and,  indeed,  as  fiill  and  complete  as  existing  ma- 
terials would  permit.

EEPOET. 


It  has  been  thought  proper  to  accompany  tlie  present  publication  of  Meteorological  Observations 
hy  a  general  review  of  the  prominent  features  of  American  Climatology,  so  far  as  the  basis  afforded 
by  the  published  observations  of  the  Army  Medical  Bureau  would  warrant  positive  deduction.  The 
period  embraced  by  these  observations  is  now  sufficient  to  afford  the  great  desideratum  of  well- 
deteimined  mean  q^uantities  in  the  conditions  which  have  positive  numerical  measures  ;  and  from  this 
basis  of  mean  results  the  range  of  extremes  may  be  measm-edj  and  the  general  character  of  the 
irregular  changes  of  successive  months  and  years  may  be  quite  thoroughly  examined  and  illustrated. 
Each  of  the  classes  of  observation  may  be  analyzed  in  this  manner,  and,  though  arbitrary  values 
are  assigned  to  the  force  of  winds  and  to  the  clearness  of  sty,  the  general  results  of  each  notation 
may  be  compared,  for  the  various  districts,  with  sufficient  definiteness.  In  any  general  system  of 
observations,  also,  whatever  errors  exist  in  the  use  of  scales  of  notation,  or  in  the  reading  of  instru- 
ments, are  usually  uniform  throughout  that  system ;  and  the  comparison  of  its  results  at  separate 
stations  among  themselves,  will  readily  disclose  the  contrasts  and  measures  of  difference  of  each 
position,  and  for  any  month  or  single  date  compared.  In  such  a  uniform  system,  successive  dates  or 
periods  may  also  be  compared  with  equal  effectiveness  ;  and  this  joint  comparison  of  various  districts, 
at  the  same  dates  and  for  successive  periods,  constitutes  the  most  thorough  and  satisfactory  analysis 
possible,  and  it  will  be  found  to  eliminate  every  considerable  error  in  reduction  and  to  develop  their 
prominent  points  of  value  with  great  distinctness. 

In  the  extent  of  area  embraced  by  these  observations  there  is  scarcely  a  precedent  in  climatolog- 
ical  investigation.  The  last  five  years  occupy  the  opposite  coasts  of  the  continent  almost  equally, 
and  the  more  important  interior  districts  are  also  well  represented.  Of  the  unoccupied  portions  of 
the  interior,  west  of  the  Eocky  mountains,  there  are  some  representative  stations,  and  there  is  a 
known  identity  of  the  general  features  of  climate  over  every  portion  of  this  area.  As  a  whole,  the 
field  is  an  entire  contiiiental  area  in  tempei-ate  latitudes,  with  the  normal  sea-climates  of  these  latitudes 
on  each  side.  "With  so  great  diversity  of  surface  and  configuration  as  the  western  part  of  the  conti- 
nent presents,  we  may  anticipate  almost  every  peculiarity  of  climate  known  to  these  latitudes  also, 
and  if  the  observations  in  the  new  districts  were  extended  over  a  greater  period  of  time  the  whole 
collection  should  form  the  best  possible  basis  for  determining  what  the  normal  or  natural  climates  of 
the  temperate  latitudes  are — the  normal  distribution  of  heat  and  moisture  particularly. 

The  period  of  time  is  sufficient  for  most  purposes  of  the  comparison  of  successive  dates.     For  the

records  at  stations  in  the  Mississippi  valley,  and  eastward,  it  is  sufficient  to  throw  great  light  on  the 
questions  of  permanence  of  temperature,  and  of  other  conditions,  and  on  the  rLuestion  whether  there 
is  any  periodicity  or  regular  return  of  the  changes  of  temperature  and  of  the  quantity  of  rain.  The 
single  measures  of  variability,  occurring  in  the  last  few  years,  may  he  partially  compared  for  the 
opposite  portions  of  the  continent,  and  may  give  us  some  approximation  to  these  measures  for  the 
western  interior  and  the  Pacific  coast,  and  though  the  mean  results  there  are  for  imperfect  periods,  if 
there  are  great  progressive  changes  of  temperature,  or  of  any  other  condition,  or  decisive  periods  of 
return  in  the  measures  of  disturhance  or  variation,  some  outline  of  them  should  appear  in  this  connec- 
tion. If  such  changes  exist  they  cannot  fail  to  appear,  in  some  degree,  in  the  more  extended  series 
at  the  older  military  posts,  and  in  the  comparison  of  different  parts  of  the  continent  for  recent  years. 
There  are  but  two  positive  measurements,  those  of  the  hygrometer  and  barometer,  which  are  not 
embraced  in  the  present  reductions  and  publication,  and  these  are  less  necessary  than  others  to  the  first 
collection  of  materials  for  climatological  investigation.  The  frequency  and  amount  of  rain  is  a  rude 
general  measure  of  humidity,  and  taking  these  data  with  the  accompanying  temperatures,  the 
deductions  based  on  the  quantity  of  moisture  contained  in  the  air  are  generally  outlined.  It  is  easy 
to  distinguish  the  districts  characterized  by  great  proportions  of  moisture  for  any  part  of  the  year,  and 
also  those  marked  as  extremely  arid,  of  which  last  there  are  striking  examples  in  the  interior  and  near 
the  Pacific.  It  is  more  difficult,  however,  to  obtain  any  outline  of  the  results  of  barometric  measure- 
ments without  use  of  such  observations  directly.  The  mean  differences  of  atmospheric  weight  are  to 
some  extent  derivable  from  the  altitudes  of  the  posts,  and  most  of  these  altitudes  have  been  determined 
with  great  care  from  barometric  and  level  surveys.  The  barometric  mean  of  Santa  F^  is  hut  about 
twenty-four  inches,  or  a  diminution  of  one-fifth  of  the  atmosphere  at  sea-level,  and  this  would  be  the 
proportion  for  a  very  large  area  of  the  interior.  A  still  larger  area  has  an  altitude  of  four  thousand 
feet,  with  a  barometric  mean  of  twenty-five  and  three-fourths  inches  nearly — one-seventh  less  than 
the  atmosphere  at  sea-level.  Some  general  idea  of  the  relation  of  the  altitude  and  mean  position  of 
the  barometer  may  be  gained  by  converting  these  altitudes  into  barometric  readings,  and  bearing 
them  in  mind  in  considering  other  conditions.  The  oscillations  of  the  barometer  are  very  important 
in  the  climates  east  of  the  Bocky  mountains,  and  they  may  generally  be  taken  as  always  large  in 
the  colder  months.  "What  their  precise  relation  to  any  feature  of  temperature  changes,  or  to  other 
peculiarities  may  he,  would  be  difficult  of  determination  in  any  case. 

The  most  important  result  which  these  records  appear  adequate  to  define  is  the  Distribution  of 
Seat  on  the  continent,  and  this  distribution  may  be  examined  as  well  for  periods  of  time  through  a 
series  of  years,  as  in  regard  to  space  at  the  same  time,  or  in  the  comparison  of  districts.  They  also 
embrace  vertical  distribution,  or  the  comparison  of  results  at  all  altitudes  below  eight  thousand  feet, 
and  in  this  feature  they  give  new  views  of  the  temperature  of  districts  at  these  altitudes,  as  distinguished 
from  that  of  isolated  mountains,  or  of  vertical  ascents  from  a  plain.  A  large  portion  of  the  interior, 
extending  from  the  southern  boundary  of  New  Mexico  at  El  Paso  to  the  sources  of  the  Missouri,  may 
he  regarded  as  made  up  of  alternations  of  mountain,  plain,  and  valley,  rising  and  falling  from  a 
mean  line  elevated  five  thousand  feet  above  the  sea.  Even  the  imperfect  periods  and  scattered  stations 
here  must  give  new  and  valuable  results  in  regard  to  the  temperature  distribution  for  such  altitudes. 
The  second  principal  result  is  the  Sistnbution  of  Bain,  or  of  atmospheric  precipitation  in  rain  and 
snow,  and  this  distribution  has  the  same  features  as  that  of  temperature  in  regard  to  the  comparisons 
of  the  various  districts  and  periods  of  time.

The  illustration  of  these  two  leading  conditions  is  given  mainly  for  the  mean  results,  though  the 
extremes  have  in  some  instances  teen  noted  in  a  similar  graphic  representation.  The  recognized 
value  of  thermal  lines  renders  their  use  necessary  to  show  the  distribution  of  heat,  yet  shaded  areas 
would  be  more  expressive  in  representing  the  greater  and  less  measures  for  the  different  districts. 
The  use  of  shaded  areas  in  showing  the  rLuautity  of  rain  is  too  well  estahlished  to  admit  of  change, 
and  the  borders  of  these  areas  rec[iiirG  to  be  marked  as  though  they  were  abrupt  limiting  lines,  as  iu 
the  case  of  the  isothermals,  yet  the  q^uantities  in  both  cases  pass  into  each  other  by  insensible 
transitions — the  line  on  the  thermal  chart  and  the  edge  of  the  shading  in  the  rain  illustration  marking 
the  boundaries  of  areas  differing  according  to  the  figures  given  them  in  each  case.  The  district 
between  two  isothermals  is,  however,  at  the  mean  of  the  temperatures  marked  on  the  two  lines,  while 
the  quantities  of  rain  are  placed  on  the  central  portions  of  these  areas  and  not  on  the  bordering  lines. 
The  peculiar  physical  contrasts  of  altitude  and  surface  required  a  map  for  the  basis  of  this 
illustration  rather  than  a  chart,  and  the  more  important  of  these  features  were  therefore  brought  out 
upon  it  as  clearly  as  might  readily  be  done  without  confusing  the  illustration.  East  of  the  Kocky 
mountains  the  vertical  topography  is  not  particularly  important,  and  the  elevated  districts  are, 
therefore,  only  indicated  at  their  borders,  or  as  plateaux.  The  AUeghany  or  Appalachian  range 
declines  at  both  extremities,  and  no  great  interruptions  of  the  isothermal  lines  appear  in  passing  it, 
the  interior  valleys  rising  nearly  to  the  temperatures  at  each  side.  Its  southern  portion  causes  the 
greatest  curvatures  in  passing  from  the  Ohio  valley  to  the  Atlantic,  but  these  are  all  regular  and 
intelligible. 

There  is  an  important  plateau  in  the  northwest,  at  the  head  of  Lake  Superior;  and  elevated 
districts,  less  rough  and  abrupt  than  those  near  the  lake,  denominated  cotemtx,  lie  between  the 
Mississippi  and  Missouri,  re-appearing  west  of  the  Missouri  in  the  Oote  Now,  or  Coteau  Noir,  of 
Pike  and  Long — the  Black  Hills,  as  they  are  generally  designated.  By  the  most  thorough  compari- 
son of  authorities  it  is  concluded  that  this  is  mainly  a  cotea%,  or  hill-bordered  plateau,  for  the 
portion  east  of  the  105th  meridian,  and  that  it  does  not  become  a  range  of  mountains  until  reaching 
this  meridian,  where  it  consttutes  a  portion  of  the  general  mass  of  the  Eocky  mountains.  It  is 
therefore  so  designated  on  the  map.  In  Texas  there  are  two  or  three  steps  by  which  the  altitude  of 
the  Llano  Estacado  of  three  to  four  thousand  feet  is  attained.  They  are  not  so  regular  as  is  indicated 
by  the  map,  but  this  sufficiently  defines  them  for  climatological  purposes.  The  first  rises  from  a  line 
six  hundred  feet  above  the  sea  at  San  Antonio,  to  twelve  hundred  at  Eorts  Martin  Scott,  Mason,  &c. 
The  first  chain  of  posts,  embracing  Ports  Graham,  Gates,  Lincoln,  &c. ,  is  at  the  entrances  to  this  plateau. 
The  next  uplifts  are  moro  irregular,  and  the  posts  of  the  newer  or  second  chain  are  usually  placed  in 
comparatively  deep  vallies.  Beyond  these  the  whole  country  attains  a  still  higher  level,  but  its 
mountainous  and  abrupt  features  are  mainly  on  the  southern  portion  near  the  Pecos  river.  The 
remainder  of  the  vertical  topography  is  intended  to  express  the  principal  abrupt  mountain  ranges  and 
the  general  plateaux,  and  also  to  show  the  predominaitng  chasm-like  or  caiion  character  of  the  river 
borders.  The  Colorado  of  California  and  its  branches,  and  the  middle  portion  of  theEio  Grande,  are  the 
chief  instances,  and  those  chasms  are  often  thousands  of  feet  in  quite  precipitous  descents  from  the  general 
level  of  arid  and  lofty  plains  and  mesas.  There  are  incomplete  points  in  this  topography  which  should 
be  noticed;  the  mountains  north  of  Fort  Owen  in  Oregon,  and  the  Bitter  Eoot  range  at  the  south 
and  west  of  this  point  toward  Lewis'  Pork  of  the  Columbia,  should  be  much  more  distinct.  The 
ranges  of  the  Eocby  mountains,  at  the  joint  sources  of  the  Grand  river,  the  Arkansas  and  the  Platte,

are  scarcely  complete,  as  also  the  northern  and  southern  portions  of  the  Great  Basin.  Both  these 
last  districts  are  little  known,  further  than  that  they  are  made  up  of  isolated  hasins  and  isolated 
mountain  ranges  of  great  general  elevation  ahove  the  sea. 

Some  general  features  of  the  character  of  the  surface  are  given  where  this  is  necessarily  asBoci.ated 
with  the  climate,  as  the  distinction  of  particularly  arid  districts  is  indispensable  to  a  proper  view  of 
temperature  and  rain  distribution.  They  are  distinguished  as  «rw^  districts  primarily,  and  they  may 
he  either  sand-desetts  or  sage-plains.  Those  of  the  upper  Missouri  are  barren  tracts  rather  than 
either,  ■with,  a  various  vegetation  and  often  with  profuse  rains,  but  wholly  uncultivahle  from  several 
causes.  The  arid  plains  between  the  Platte  and  Canadian  rivers  are  in  greater  part  saiid-deserts, 
especially  in  the  vicinity  of  Long's  and  Pike's  Peaks,  and  south  of  the  ArkansEia.  The  Llano  Esta- 
cado  is  a  dry  plain  of  clay  and  alkaline  earths,  a  portion  of  it  covered  with  coarse  vegetation,  for  part 
of  the  year  at  least,  and  a  portion  near  the  Pecos  is  again  sand-desert.  The  "sage-plains,"  or  dry 
districts  with  little  vegetable  growth  except  varieties  of  arten  '"ah  '  on  the  western  border  of 
the  plains  of  the  eastern  Eoeky  mountain  slope,  and  cover  u  u  h  the  la  ger  portion  of  the  whole 
country  we&tward ;  and  this  predominating  aridity  it  was  qu  e  nt  al  to  represent  in  connection 
with  the  distribution  of  temperature  and  of  rain.  In  the  vail  j  f  the  1  -er  Rio  Grande  a  portion 
of  the  arid  district  is  sandy;  and  the  Jornada  del  Mnerto  ot  the  ].p  Hio  G-rande,  between  Fort 
Craig  and  Dofia  Ana,  is  mainly  sand-desert.  That  of  the  Colorado  of  California  is  the  principal 
sand-desert,  however,  and  it  embraces  a  large  area  of  the  southern  part  of  the  Great  Basin,  In  the 
vicinity  of  Fort  Yuma  the  sands  alternate  with  tracts  of  clay,  and  these,  with  saline  lakes  and  hasins, 
and  short  abrupt  mountain  ranges,  make  up  almost  the  whole  of  the  Great  Basin  of  the  interior.  In 
Oregon  the  desert  notation  is  applied  to  districts  half  sands  and  half  sage-plains,  as  in  other  cases. 

But  one  distinction  of  a  humid  district  is  made,  which  is  that  near  the  Mississippi  and  along  the 
Gulf  coast  to  Florida,  surrounded  by  an  interrupted  line.  It  defines  the  district  of  greatest  precipi- 
tation in  rain,  and  of  the  greatest  prevalence  of  surface  waters  derived  from  atmospheric  precipitation. 
Whether  these  facts  react  on  the  climate  is  a  question  which  has  often  been  asked.  In  a  portion  of 
this  district  lagoons  and  bayous  characterize  the  surface,  and  the  rivers  are  marked  by  numerous 
lake-like  expansions,  and  in  other  portions  the  heavy  rains  are  immediately  borne  off  by  rivers  of 
sufficiently  rapid  descent.  The  distinguishing  feature  is  thus  the  abundance  of  water  falling  in  rain 
as  a  constant  result,  and  either  with  or  without  the  presence  of  waters  so  derived  in  great  quantity  on 
the  surface,  A  district  at  the  sources  of  the  Mississippi  is  distinguished  for  the  great  niunber  of  its 
fresh-water  lakes  and  ponds,  and  it  has  profuse  rains  at  some  period  of  the  year,  but  its  general 
temperature  is  too  low  to  identify  it  with  that  of  the  lower  Mississippi,  or  to  render  its  introduction 
into  a  physical  chart  necessary.  On  the  Pacific  coast  of  Oregon  there  are  also  excessive  rains  at  the 
cold  season,  and  farther  up  this  coast  gi-eat  quantities  of  water  so  accumulated  characterize  the  general 
surface,  but  tliese  are  features  of  a  climate  generally  cold,  and  are  found  in  much  of  British  America 
and  in  northwestern  Europe. 

The  observations  here  published  form  a  very  ample  basis  for  examination  of  all  the  general 
features  of  climate  not  obseiTed  instrumentally.  The  winds  have  a  prominent  place,  and  it  is  easy  to 
distinguish  the  general  features  of  atmospheric  circulation  in  the  mean  results  of  even  the  arbitrary 
notation  necessarily  employed  in  observation.  For  the  purpose  of  giving  the  nearest  approximation 
to  true  results  the  great  labor  of  combining  the  sums  of  the  numbers  denoting  force  has  been  under- 
taken, and  in  the  summaries  for  single  months  and  for  tlie  year  the  advantages  of  this  course  are  very

apparent,  and  the  differences  from  simple  numerical  results  show  tlie  direction  in  wliicli  the  qnantities 
should  he  further  clianged  to  represent  the  actual  movement  in  miles  per  hour.  If  the  "  sum  of 
force"  is  in  one  case  three  times  as  great  as  the  numher  of  winds,  and  in  another  hut  twice  as  great, 
the  disproportion  would  be  doubled,  at  least,  if  the  movement  were  truly  represented  in  miles  per 
hour.  A  very  good  resultant  movement  may  be  derived  from  the  sums  of  force  in  all  cases,  and  the 
irregularities  may  thus  be  reduced  to  the  mean  movement  with  sufficient  precision  to  show  what  all 
the  important  movements  of  surface  atmosphere  are. 

The  douds  and  forms  of  predpUatum  in  rain  and  snow,  with  the  general  phenomena  defined  by 
the  term  weather,  complete  the  list  of  distinctive  subjects  observed.  These  may  not  be  compared  as 
positive  c[uantitie8,  like  the  temperature  and  rain  measurements,  but  they  are  of  great  practical 
interest,  and  are  readily  understood  in  any  scale  of  notation.  These  observations  are  sufficient  for  a 
more  thorough  examination  than  can  now  be  made,  and  some  of  the  more  prominent  points  of  interest 
only  can  receive  attention. 

The  statistics  of  temperature  and  amount  of  rain  will  he  regarded  as  quantities  determined  with 
sufficient  accuracy  for  any  piu'poee  of  scientific  comparison,  and  the  numher  of  ohservations  combined 
in  the  results  that  are  used  is  tliought  sufficient  to  neutralize  every  considerable  error  in  their  details, 
and  to  leave  no  doubt  of  the  general  correctness  of  the  positions  they  are  assumed  to  establish. 
Where  observations  are  so  greatly  multiplied  the  principal  care  is  reqirired  in  their  arrangement,  and 
in  the  mode  of  presenting  them,  and  when  this  is  correctly  done  they  are  easily  seen  to  establish 
some  general  conclusions,  and  it  only  becomes  necessary  to  recognize  and  illustrate  these  in  an  intelli- 
gible manner.  In  this  mode  of  treatment  there  is  no  necessity  for  the  introduction  of  theoretical 
views,  and  there  are  few  occasions  for  reference  to  remote  causes  or  to  the  solution  of  anomalies  and 
striking  features  of  the  results  beyond  what  is  clearly  seen  to  be  the  necessary  relations  when  the 
points  are  explained.  It  is  sometimes  necessary  to  go  beyond  the  limits  of  the  continent  to  explain 
some  features  of  the  climate,  however,  but  in  the  present  case  such  references  may  be  made  to  very 
reliable  observations,  and  the  resulting  illustration  is  entirely  satisfactory. 

Nearly  every  feature  may  also  be  illustrated  and  explained  by  the  use  of  numerical  quantities  and 
of  positive  measurements.  Even  in  the  case  of  wind  and  weather  phenomena,  the  use  of  a  numerical 
notation  has  great  advantages  over  the  use  of  symbols  or  of  descriptive  terms  for  the  purposes  of 
general  comparison,  and  the  leading  results  are  much  more  readily  disclosed  in  the  summaries.  It 
is  not  essential  that  the  scales  of  notation  should  represent  absolute  quantities,  if  the  approximation 
is  reasonably  near,  and  there  has  yet  been  no  instrumental  measurement  of  winds  which  gives  better 
results  than  the  estimate  of  the  observer  carefully  made  in  a  scale  of  one  to  ten,  and  the  interpreta- 
tion of  these  numbers,  separately,  iu  miles  per  hour.  The  summaries  of  these  observations  here  given 
include  the  "sum  of  force"  obtained  by  adding  the  recorded  numbers  of  this  scale,  and  they  are,  by 
so  much,  a  nearer  approximation  to  positive  results  than  the  sums  of  the  number  of  observations  only. 
Each  of  the  arbitrary  scales  of  notation  was  fortunately  well  adapted  to  the  habit  of  observers^  and 
they  were  uniform  over  so  great  a  period,  and  embrace  so  great  a  number  of  observations  in  the  sum- 
maries, that  they  have  unusual  value,  and  may  be  relied  upon  as  expressing  quite  positive  results. 

It  is  proper  to  state  in  this  connection  the  general  principles  which  have  controlled  the  designation 
of  observations  as  inaccurate  in  any  case,  and  the  rejection  of  single  observations  or  entire  records  in 
the  computations.  It  is,  of  course,  impossible  to  submit  a  mass  of  observations  of  this  character  to 
rigid  analytical  tests  in  detail,  or  even  in  the  degree  of  detail  which  may  be  applied  to  the  summa-

rles  as  single  results.  Tlifi  i^rciit  reliance  for  (sliminatiTig  errciv  in  ii,ll  oases  has  been  such  compn,rlson 
as  it  was  possible  to  make  in  recognition  of  the  natural  symmetry  of  this  class  of  phenomena.  This 
symmetry  appears  as  decidedly  in  the  relations  of  general  distribution  as  in  those  of  succession  or 
continuation  ;  or,  in  other  words,  different  portions  of  a  general  district  show  a  correspondence,  in 
mean  results  particularly,  analogous  to  the  correspondence  of  successive  observations  at  any  one  point. 
Changes  of  temperature  may,  indeed,  to  a  certain  extent,  exchange  place  for  time  in  the  districts 
where  the  atmospheric  movements  are  considerable. 

Marked  discrepancies  or  departures  from  this  general  symmetry  are,  therefore,  conspicuous  in 
any  class  of  observations  of  this  character,  and  they  may  be  readily  and  safely  detached  from  any 
connection  which  they  clearly  distort.  Observations  of  temperature,  particularly,  may  be  so  distin- 
guished, and  their  measm^e  of  error  defined,  by  mere  inspection  in  the  proper  arrangement,  and 
the  application  of  the  most  elaborate  formulre  of  elimination  would  accomplish  little  more  for  results 
of  this  character.  The  number  of  observations  is  now  such  in  this  depai'tment  of  meteorology  that  no 
series  of  them  is  isolated,  or  is  dependant  on  itself  alone  for  principles  of  correction,  but  all  are  points 
in  a  general  ftame-work  of  mutual  relations  and  mutual  dependance.  It  ismainlythepower  of  afield 
so  extensive  to  perfect  its  own  proportions  and  symmetry,  both  in  time,  and  in  place  or  area,  which  is 
relied  upon  in  deduction  from  the  temperature  records  in  the  present  case,  and  if  the  criticism  and  com- 
parison shall  have  been  made  with  the  proper  care,  the  results  are  believed  to  be  as  reliable  as  any 
which  may  be  reached  at  present  in  this  field,  and  to  be  substantially  correct  as  a  whole.  A  rigid 
mathematical  analysis  applied  to  these  principal  series,  and  to  their  combination  hy  districts,  is  the 
most  desirable  work  remaining  to  be  done,  and  to  show  what  light  the  principal  series  of  meteor- 
ological observation  which  have  been  carefully  discussed  throw  on  this  point  it  may  be  well  to  refer 
to  them  here.  The  best  published  series  of  American  observations  were  made  nearly  at  the  same 
dates  by  Captain  Mordecai,  at  the  I'rankford  Arsenal,  near  Philadelphia ;  by  Lieutenant  Gilliss,  at 
the  Naval  Observatory ;  by  Professor  Bache,  at  the  observatory  of  Girard  College,  Philadelphia ;  and 
by  Captains  Eiddle  and  Lefroy,  at  Toronto,  at  the  observatory  established  by  the  British  government. 
The  first  series  began  in  1835,  and  was  continued  five  years;  the  next  two  in  1840,  continuing,  one 
four  and  the  other  five  years;  and  the  last  in  1841,  continuing  twelve  years.  The  constants  derived 
from  these  series  were  perfect  representatives  of  the  conditions  of  temperature  for  these  periods,  and 
the  conformity  of  these  results  with  them  or  their  differences  may  show  what  approximation  to  posi- 
tive results  of  a  constant  character  are  now  made. 

The  results  of  the  longest  period  of  observation  at  Toronto  have  recently  been  analyzed,  with 
great  care,  by  Colonel  Sabine,*  and  the  leading  features  of  temperature  and  rain  distribution  disclosed 
are  taken  as  sufficiently  established  by  this  record  alone.  Prominent  among  these  is  the  apparent 
removal  of  the  winter  minimum  of  temperature  to  February  14th,  or  fifty-five  days  after  the  winter 
solstice,  while  the  summer  maximum  is  twenty-eight  days  only  after  the  summer  solstice.  This  is 
noticed  as  an  extraordinary  anomaly  in  comparison  with  the  European  climate,  the  moan  at  several 
European  stations  cited  in  that  connection — Konigsberg,  Berlin,  Prague,  Paris,  Padua,  and  Turin- 
giving  July  25th  as  the  date  of  the  maximum,  and  January  15th  as  that  of  the  minimum  temper- 
ature for  the  year.  Comparing  this  with  the  first  result,  the  difference  for  the  summer  is  but  three 
days  and  that  for  the  winter  thirty  days — showing  the  existence  of  a  large  anomaly  in  the  American

climate.  By  a  rough  com'panaon  of  this  Toronto  series  with  others  here,  liowever,  we  find  that  it 
embraces  the  greatest  non-periodic  depression  of  temperature  known  to  our  records,  and  that  a  series 
which  does  not  include  tte  year  in  which  this  occurs,  1843,  or  one  covering  a  period  so  great  as  to 
reduce  its  prominence,  gives  a  very  different  position  for  the  coldest  month  and  the  coldest  day,  and, 
in  trathj  removes  the  apparent  anomaly  in  the  constant  distribution,  altogether.  Of  the  series  at 
the  military  posts  that  at  Fort  SnoUing,  for  thirty-five  years,  gives  i.°2  as  the  increase  of  heat  in 
February  over  January,  instead  of  1. ''.ST  diminution,  as  at  Toronto  ;  that  at  Watervliet,  near  Albany, 
ibr  thirty-one  yearfj,  0°.9  ;  and  that  at  West  Point,  for  the  same  period,  0°.52  excess  in  February 
-orer  January,  Flirts  Brady,  Mackinac,  and  "Winnebago  are  the  only  extended  series  conforming  to 
that  at  Toronto ;  tind  at  each,  removing  this  extreme  year,  the  proportions  are  restored  to  those  found 
elsewhere,  Tl^  district  of  the  great  lakes  has  some  effect  in  throwing  the  cold  minimum  forward, 
and  probably  t\e  mean  of  the  most  extended  period  would  show  some  anomaly  for  a  district  central 
at  Toronto ;  hut  it  is  readily  seen  that  it  does  not  belong  to  the  eastern  United  States  generally.  If 
we  had  -obserT'ations  in  a  similar  district  of  the  eastern  continent,  a  similar  prolongation  of  the  period 
of  the  greatest  cold  would  probably  appear,  and  there  would  be  found  no  anomalous  temperature 
distrihutioin  belonging  to  the  United  States  in  regard  to  the  extremes  of  the  annual  curve.  There 
are  other  references  to  this  series  in  connection  with  examinations  of  the  annual  curve  of  temperature 
and  the  igeneral  distribution  for  the  year. 

The  other  series  here  referred  to  do  not  cover  a  period  sufftcient  to  fix  any  similar  point  in 
generafl  climatology,  or  to  determine  any  other  constants  than  those  of  daily  variation  of  tempera- 
ture. As  the  use  of  precise  formulas  for  correction  of  the  various  hours  of  observation  deduced  from 
such  series  has  not  been  made  in  these  temperature  statistics,  they  may  be  referred  to  as  evidence 
1;hat  the  mean  of  extensive  periods  of  observation,  in  a  uniform  system,  is  adec^uate  to  show  the 
^striking  features  of  general  climatology  without  this  detailed  correction,  and  that  short  periods,  of 
ih.e  most  precise  observations,  may  mislead  in  regard  to  these  more  general  features.  An  extended 
district,  and  extended  periods  at  several  points,  become  indispensable  to  such  a  purpose,  and  the  use 
of  such  a  mass  of  observations,  as  a  whole,  does  not  absolutely  require  precise  analysis  of  its  separate 
series.

DISTRIBUTION  Oi!'  TEMPERATURE, 


EXPLANATION   OP  THE   ISOTHERMAL  GHAUTS. 


MEAK   DISTRIBUTION   OF   TEMPERATURE    EOE   THE   THREE   MONTHS  OF  SPRING. 


The  diatinguisliing  feature  of  the  distribution  of  heat  for  the  spring  over  the  area  covered  hy 
these  observations  is  its  variability,  first  through  the  separate  months,  next  in  the  differences  which  these 
give  among  themselves  at  any  point,  and  again  in  the  comparison  of  districts.  The  mean  of  the  whole 
period  hasj  for  this  reason,  less  of  the  character  of  a  positive  quantity  for  comparison  than  the  means 
for  summer  and  for  winter,  and  the  relation  of  the  single  months  is  not  so  direct  in  comparing  districts 
as  in  other  seasons.  In  some  parts  of  the  territory  occupied  by  the  military  posts  March  has  all  tlie 
characteristics  of  a  winter  month,  and  in  others  May  advances  fully  into  the  summer.  In  some 
general  districts,  as  on  the  Pacific  coast  below  the  40th  parallel,  the  temperature  is  very  uniform 
through  these  months,  and  in  others,  as  on  the  central  and  northern  portion  of  the  Great  Plains,  the 
differences  are  quite  extreme  between  March  and  May.  The  greater  area  of  the  United  States, 
however,  exhibiis  a  considerable  advance  in  March  on  the  mean  temperature  of  February,  and  April 
and  May  show  nearly  uniform  differences  throughout,  April  dividing  the  extremes  quite  equally,  and 
representing  the  mean  of  the  three.  When  this  is  the  case  the  season  may  be  regarded  as  an 
identified  period,  capable  of  sufficiently  clear  definition  as  a  constant,  and  of  a  distinct  illustration. 

As  a  whole  the  western  half  of  the  continent  is  much  the  warmest  for  these  months,  and  if  the 
mountain  plateaus  did  not  intervene  the  isothermals  would  be  quite  uniform,  without  correction  for 
the  lower  altitudes,  in  their  direction  across  the  continent  from  west-north-west  to  east-south-east. 
There  is  a  partial  exception  in  the  lake  district  to  the  uniformity  of  this  direction,  and  a  great 
accession  of  heat  occurs  in  the  interior  plains  west  of  the  Rocky  mountains  as  compared  with  adjacent 
districts,  though  this  does  not  constitute  a  decided  anomaly  in  the  general  course  of  the  lines  and 
distribution  just  alluded  to.  All  the  measures  observed  in  the  interior  at  considerable  altitudes  are 
greater  than  would  be  found  at  the  same  altitudes  of  southern  Europe. 

The  relation  of  the  continental  or  interior  temperatures  for  these  months  to  those  of  the  Atlantic 
and  Pacific  oceans  show  less  of  contrast  than  in  summer.  On  the  Atlantic  coast  the  mean  of  the 
three  months  would  continue  the  lines  without  curvature  to  the  Grulf  stream,  where  they  would  curve 
considerably  northward,  and  follow  its  general  course  for  some  distance.  On  the  Isothermal  Chart  the 
position  of  the  Gulf  slream  is  given  roughly  or  generally,  as  its  influence  on  the  temperature  of  the

sea,  in  contrast  with  that  of  the  land,  should  be  recognised  at  all  times  when  the  illnstrationa  of  land 
temperatures  is  considered.  For  the  northern  part  of  the  stream  the  designation  is  brought  nearer 
the  coast  than  the  axis  of  the  warm  Current,  and  it  there  represents  rather  the  portion  which  is  so 
near  the  coast  as  to  make  reference  to  it  necessary  than  the  principal  volume  of  warm  water. 

In  May  the  sea  within  the  Gulf  stream  is  much  colder  than  the  continent  generally,  as  the 
movement  of  drift  ice  and  cold  currents  from  the  Arctic  seas  is  then  more  decided  than  in  the  preceding 
months,  while  in  March  the  northern  portion,  at  least,  is  relatively  much  warmer.  The  mean  of  32° 
for  this  last  month  has  its  position  in  the  southern  part  of  New  England  and  New  York,  and  it 
extends  along  most  of  the  coast  of  Maine  and  at  sea  in  the  direction  of  the  southern  extremity  of  New- 
foundland, passing  this  point  at  a  short  distance  from  the  land,  in  the  narrow  belt  which  lies  between 
the  land  and  the  warm  atmosphere  of  the  G-ulf  stream.  The  observations  which  have  been  made  at 
Halifax  and  at  St.  Johns,  Newfoundland,  indicate  the  existence  of  influences  greatly  depressing  the 
temperature  of  April  and  May  and  rendering  the  mean  for  the  whole  season  below  that  of  the  same 
latitudes  inland.  The  mean  of  five  years  observation  at  St.  Johns  gives  32°.  3  as  the  spring  tempera- 
ture, while  at  Albion  Mines,  Nova  Scotia,  the  mean  for  ten  years  is  37°. 6*,  and  at  the  more  northern 
military  posts,  Forts  Kent  and  Fairfield,  it  is  above  35°. 

The  course  of  the  isothermals  of  the  higher  latitudes  of  the  chart  is  nearly  due  west  from  the 
Atlantic  coast,  except  where  local  divergence  from  this  line  is  caused  by  the  lakes,  to  the  meridian  of 
Fort  Snelling,  where  the  lines  from  45°  to  30°,  inclusive,  make  remarkable  curvatures  northward 
over  the  northwestern  plains.  The  statistics  of  the  military  posts  at  present  only  indicate  this  result 
generally,  and  the  observations  of  the  military  surveys,  and  at  the  posts  of  the  Hudson's  Bay  Company 
have  been  relied  upon  for  definite  positions  here.  The  valley  and  plains  of  the  Saskatchewan  river  are 
shown  by  Richardson  to  have  a  much  higher  temperature  than  the  districts  east  in  the  same  or  even 
in  lower  latitudes  ;  the  south  branch  of  this  river,  in  latitude  51°,  being  distinguished  by  an  early 
and  rapid  advance  of  temperature,  giving  a  mean  for  May  even  greater  than  that  observed  in  the 
vicinity  of  the  great  lakes  generally.  The  observations  at  Fort  Benton,  Fort  Pierre,  and  Fort 
Laramie  confirm  these  positions  sufficiently  to  render  this  apparent  anomaly  clearly  an  established  fact 
of  distribution.  The  higher  temperatures  in  these  districts  belong  to  each  of  the  spring  months  in 
nearly  the  same  degree,  and  they  will  appear  less  extraordinary  if  we  could  suppose  the  great  altitudes 
of  the  Rocky  mountains  removed  and  a  configuration  there  similar  to  that  of  western  Europe. 

On  the  Pacific  coast,  as  on  the  Atlantic,  a  considerable  falling  off  from  the  land  temperatures 
occurs,  especially  in  the  last  month.  For  the  mean  of  the  three  months,  the  sea  temperatures 
observed  off  this  coast  are  strikingly  uniform,  and  they  show  but  little  if  any  advance  on  those  of 
winter.  For  some  hundreds  of  miles,  on  the  40tli  parallel,  there  is  very  little  difference  in  the  sea 
temperatures  for  the  entire  year  ;  and  in  spring  such  observations  as  we  possess  show  them  to  be 
q^uite  the  same  between  the  35th  and  40th  parallels  for  thirty  degrees  of  longitude  westward  from 
San  Francisco.     The  observations   given   in  Maury's   Charts   furnish  about   twenty  measurements

for  each  avea  of  five  degveew  extent,  in  both  latitude  and  longitude,  and  the  means  are  56°  to  the 
125tli  meridian,  55°. 4  to  the  130th,  55°. 5  to  the  135th,  56". 4  to  the  140th,  57°. 2  to  the  145th,  and 
56°  for  the  last  observed  area,  bounded  on  tlie  west  by  the  meridian  of  150°  west  longitude.  These 
successive  results  are  substantially  identical,  and  they  confirm  the  records  at  the  military  posts  of  the 
coast,  explaining  the  cause  of  the  singular  contract  of  their  temperatures  with  those  of  the  interior, 
in  showing  very  little  increase  of  heat  as  the  summer  approaches.  It  will  be  seen  by  reference  to  the 
analysis  of  the  summer  distribution,  that  the  sea  then  remains  nearly  at  the  same  temperature  for  seven 
or  eight  degrees  of  longitude  off  the  coast,  while  beyond  that  point  it  shows  some  increase  of  heat  for 
May,  and  a  rapid  change  for  the  months  of  summer.  From  this  evidence  the  iaothermals  would, 
apparently,  extend  in  right  lines  westward,  on  leaving  the  coast  in  spring,  while  in  summer  they 
curve  abruptly  northward,  after  passing  the  cold  mass  of  water.  The  Pacific  climates  appear  to  be 
distinguished  for  the  identity  of  the  air  and  loater  temperatures,  so  far  as  observed,  at  least  the 
differences  are  so  small  that  it  is  not  necessary  to  separate  them  in  the  purpose  of  this  comparison. 

By  reference  to  the  Isothermal  Chart  for  spring  the  advance  in  temperature  from  April,  or  the 
mean  of  the  three  months,  to  May,  is  seen  to  be  very  little  for  the  immediate  coast,  the  line  of  55° 
leaving  it  near  Monterey  in  both  eases.  The  same  lino  for  March  differs  most  from  any  other,  as  this 
is  but  little  north  of  San  Diego  at  its  point  of  departure  from  the  coast.  The  measure  of  difference 
of  these  extreme  positions  is,  howerer,  less  than  three  degrees  of  latitude,  while  in  the  Mississippi 
valley  the  mean  of  55°  for  March  falls  southward  of  Fort  Towson,  to  33°  of  latitude, [and  rises  in  May 
above  Fort  Snelling,  to  latitude  4(1°,  a  range  of  thirteen  degrees,  dividtid  t|uite  equally  by  its  mean 
position  at  St.  Louis. 

The  cause  of  this  peculiar  unifomiity  of  temperature  on  the  Pacific  coast  will  again  be  referred  to 
in  connexion  with  the  summer  distribution,  as  it  then  attains  its  maximum  influence,  and  its  charac- 
teristics may  he  more  readily  recognized. 

The  relation  of  the  spring  temperatures  of  the  interior  of  northern  Mexico  to  those  of  the  adjacent 
districts  of  the  United  States  cannot  be  noticed  for  want  of  observations  there,  A  large  area  of  dry 
basins  south  of  the  Eio  Grande,  and  extending  from  El  Paso,  with  some  interruptions,  to  the  Gtulf  of 
Mexico,  is  warm  at  all  seasons,  and  the  isothermals  of  the  Rio  Grande  above  Fort  Mcintosh  may 
usually  be  continued  northwestward  at  least  across  the  Boleon  de  Mapimi,  The  mountainous  districts 
south  and  westward  of  these  basins  are  relatively  warmer  in  spring  than  in  summer,  though  none  of 
this  interior  probably  attains  the  temperatures,  either  in  spring  or  summer,  of  the  Lower  Rio  Grande 
and  Colorado  valleys.  The  temperature  at  Vera  Cruz  for  the  spring  is  77°,  and  there  is  probably  no 
part  of  the  coasts  of  Mexico  northward  which  exceed  this,  and  few  which  attain  the  mean  of  75°, 
observed  at  Fort  Yuma  and  the  military  posts  of  the  Lower  Eio  Grande. 

In  the  West  India  islands  the  spring  temperature  is  above  that  at  Key  West,  though  the  southern 
portion  of  Florida  is  tropical,  the  mean  at  Havana  and  other  points  being  78°  to  79°. 5,  There  is 
probably  no  point,  therefore,  where  the  land  temperature  exceeds  that  of  the  sea  southward,  or  of  the 
Gulf  of  Mexico,  though  they  differ  very  little  for  the  warmer  positions  named, 

The  principal  lines  of  the  Isothermal  Chart  differ  five  degrees  in  temperature,  and  east  of  the 
meridian  of  100°  they  divide  distance  on  the  meridians  with  great  uniformity.  On  the  Atlantic  side 
the  range  is  thirty-five  degrees  of  temperature  for  twenty-two  degrees  of  latitude,  or,  excluding  the 
lower  part  of  the  peninsula  of  Florida,  thirty  degrees  of  temperature  for  seventeen  of  latitude,  which  is 
very  nearly  a  decrease  of  temperature  of  one  degree  for  forty  miles  of  distance  northward.     The  same

decrease  is  found  in  tlie  Mississippi  valloy,  and  on  both,  tliese  lines  tlie  altitude  does  not  attain  suffi- 
cient importance  to  sensibly  affect  this  result.  The  Pacific  side  is  too  irregular  to  give  comparable 
raeasures,  but  from  tlie  parallel  of  30°  to  Astoria,  the  same  distance  which  was  taken  in  the  first  case, 
there  is  but  one-third  the  difference  in  temperature,  or  one  degree  for  one  hundred  and  twenty  miles 
northing.  If  the  comparison  were  carried  to  Sitka,  latitude  57°,  hut  five  degrees  of  temperature  more 
are  lost,  ^nd  the  same  proportion  or  rate  of  diminution  is  still  maintained. 

The  relation  of  the  differences  separating  the  isothermals  of  the  principal  portion  of  the  continent 
east  of  the  Rocky  Mountains  is  such  that  the  successive  months  of  spring  would  remove  one  to  very 
near  the  position  of  another,  and  the  mean  of  65°  for  May,  of  55°  for  April,  and  of  45°  for  March, 
would  occupy  nearly  the  same  position.  The  lines  as  drawn  are  quite  correct  representatives  of  the 
temperature  of  April.  To  place  on  these  the  temperatures  of  May  the  line  of  60°  becomes  70°,  that 
of  55°  becomes  65°,  &c.  ;  and  the  reverse  if  March  is  illustrated.  This  feature  of  the  temperature 
distribution  for  these  months  will  be  better  understood  by  reference  to  the  following  measures  of 
increase  of  heat  through  the  spring  months  at  several  stations.  The  quantities  given  are  the  differences 
from  March  to  April,  April  to  May,  and  May  to  June,  ail  taken  from  the  mean  results  of  the  series. 
In  the  south  these  measures  of  difference  are  less,  and  in  the  northwest  they  are  greater  than  ten 
degrees,  but  for  much  the  largest  portion  of  the  area  east  of  the  plains  this  number  would  indicate  the 
march  of  temperature  in  these  months  quite  correctly.  The  differences  at  the  posts  of  the  Pacific 
coast  and  at  some  European  stations  will  illustrate  the  contrast  presented  in  this  season  there :

These  comparisons  sliow  that  the  advance  of  temperature  in  spring  is  quite  uniform  throuo-h  the 
three  months,  and  that  the  central  areas  of  the  United  States  correspond  witli  Germany  and  Central 
Europe  in  this  respect.  From  March  to  April  and  from  April  to  May  the  advance  is  more  regular 
than  in  the  approach  to  the  mean  for  March  and  to  that  for  June.  In  short,  the  uniformity  of  the 
advance  in  temperature  helongs  to  a  less  period  than  three  months  in  the  continental  climates.  The 
least  advance  belongs  to  the  coast  of  California,  and  it  has  been  alluded  to  already  to  some  extent. 
Even  the  interioi'  posts  of  Yuma  and  Miller,  where  excessive  heats  prevail  in  summer,  show  a  less 
rapid  march  of  temperature  in  spring  than  the  Atlantic  posts.  The  more  elevated  district  of  New- 
Mexico  alone  exhibits  the  characteristics  of  a  continental  climate  in  this  respect.  The  modified 
climates  of  "Western  Europe  appear  in  the  measures  for  London,  Paris,  &c.,  and  at  Moscow  and  Bar- 
naoul,  European  and  Asiatic  Russia,  the  great  measures  of  difference  belonging  to  the  most  extreme 
continental  climates  appear.  Fort  Eipley  gives  the  most  extreme  measures  observed  at  any  point  in 
the  United  States,  and  the  Arctic  regions  of  British  America  alone  exhibit  the  differences  which  are 
foimd  in  the  interior  of  Asia,  hut  which  are  there  connected  with  much  higher  absolute  temperatures. 
The  district  of  most  rapid  advance  of  temperature  in  spring  in  the  United  States  has  also  a 
comparatively  high  temperature  for  the  month  of  March,  so  that  the  transition  to  summer  is 
completed  before  June.  At  Council  Bluffs  March  is  warmer  than  at  Fort  Sullivan,  and  the  difference 
between  this  month  and  April  is  twice  as  great  at  the  former  post.  The  average  of  twenty  degrees 
advance  in  the  two  months  at  eastern  stations  generally  corresponds  to  an  average  of  twenty-eight  for 
a  large  area  central  at  Fort  Snelling,  and  an  average  of  twenty-five  degrees  for  a  still  larger  area 
surrounding  this,  and  reaching  to  the  lakes  on  the  east,  to  St.  Louis  and  Fort  Kearney,  and  to  near 
the  sources  of  the  Missouri  northwestward.  The  greatest  mean  advance  is  of  eighteen  degrees  for 
thirty  days,  or  six-tenths  of  a  degree  daily. 

The  irregular  or  non-periodic  distribution  of  heat  for  the  spring  is  a  feature  of  great  practical  as 
well  as  scientific  importance,  and  it  presents  more  noticeable  points,  which  do  not  appear  in  the 
determined  mean  temperatures,  than  any  other  part  of  the  year.     Some  of  the  more  prominent  of  these

appear  in'the  comparison  of  the  means  lor  the  same  month  and  of  the  same  season  for  successive  years; 
and  some  measures  of  the  last  named  variation  are  illustrated  in  the  isothermal  charts  hy  the  lines 
representing  the  maximum  and  minimum  positions  of  an  isothermal  of  any  degree.  The  areas  east 
Rocky  mountains  only  could  be  intelligihly  illustrated  in  this  manner,  as  the  periods  at  the  newer  of  the 
posts  are  insufficient  to  show  whether  the  entire  measure  of  range  is  emhraced.  This  period  is  ample 
for  the  older  posts,  however;  as  a  series  of  fifty  years  since  1800,  and  detached  series  previous  to  that 
date  from  1743,  exhibit  no  extremes  greater  than  the  low  temperature  of  1843  and  the  high  temperature 
of  1842  for  the  spring.  Extremes  scarcely  less  than  these  fall  between  the  years  1830  and  1840 
in  some  limited  districts. 

As  illustrated  by  the  lines  of  the  chart,  the  minimum  of  any  degree  is  designed  to  represent  the 
extreme  point  to  which  the  temperature  of  any  locality  on  the  line  may  fall  in  any  year,  and  not  the 
lowest  position  of  the  line  in  any  single  year  for  the  whole  area.  The  lowest  point  observed  in  the 
Mississippi  valley  rarely  occurs  at  the  same  time  that  the  greatest  extreme  falls  on  the  Atlantic  coast ; 
the  lines  are,  therefore,  the  measures  of  mammum  variability  at  each  point.  Comparing  these 
measures  on  the  Atlantic  coast,  the  range  of  the  mean  of  45°  is  from  Fort  Mifiin  to  Hancock 
Barracks,  about  seven  degrees  of  latitude,  and  somewhat  more  above  or  north  of  its  mean  position 
than  south  of  it.  In  the  west  its  greatest  range  is  from  near  Fort  Ripley  to  a  point  midway  between 
Fort  Leavenworth  and  Fort  Scott,  one  of  these  last  giving  42°. 5,  and  the  other  4T°.5  as  the  minimum 
in  1843,  and  the  short  period  at  Fort  Eipley  giving  42°. 5  as  the  maximum  in  1856,  The  measure 
of  range  at  Fort  Snelling  is  5°. 2  above  the  mean  in  1825,  and  12°. 1  below  it  in  1843.  The  same 
measure  of  range  would  give  a  maximum  of  45°  at  Fort  Eipley,  and  the  range  of  this  isothermal,  as 
thus  defined,  is  over  nearly  nine  degrees  of  latitude,  or  more  than  six  hundred  miles.  The  range  in 
distance  is  no  greater  than  this  on  the  western  border  of  the  Plains,  apparently,  though  the  isothermals 
are  much  more  widely  separated  there,  as  the  variation  of  temperatures  in  successive  years  is  certainly 
much  lees.  As  a  possible  transfer  of  the  mean  temperature  of  an  entire  season,  the  measure  for  all 
parts  of  the  eastern  and  central  areas  is  certainly  very  great,  and  it  has  no  parallel  at  the  European 
stations  where  the  same  period  has  been  observed  and  the  comparison  may  be  fairly  made. 

The  maximum  and  minimum  position  of  other  lines  between  40°  and  65°  has  nearly  the  same 
measure  of  range,  diminishing,  however,  towards  both  extremes.  There  is  some  conformity  to  a 
rule  placing  a  minimum  of  any  degree  in  the  position  of  a  mean  of  five  degrees  greater,  and  a 
maximum  on  a  mean  of  five  degrees  less  ; — thus  the  maximum  of  45°  is  nearly  identical  with  the 
mean  of  40°,  and  the  minimum  of  55°  with  the  mean  of  60°.  One  decided  exception  to  this  is 
found  in  the  greater  depression  of  the  minima  of  40°  and  45°  in  the  Mississippi  valley,  or  the  greater 
separation  of  these  from  the  mean  lines  which  they  elsewhere  so  nearly  follow.  The  greater 
depressions  of  temperature,  as  well  as  the  greater  heats  here,  attain  their  most  extreme  measures,  as 
may  be  seen  in  the  record  for  1843  particularly. 

On  the  Pacific  coast  the  measures  of  variation  would,  from  analogy,  be  much  less,  and  the 
limited  period  of  observation  gives  insufficient  data  for  illustrating  this  feature  of  variability.  At 
Fort  Steilacoom,  for  six  years,  the  greatest  range  is  2°. 5,  at  Fort  Vancouver  2°. 5,  at  8an  Francisco 
3°,  at  Benicia  4°. 5,  and  at  San  Diego  4°. 5 — the  same  six  years,  1850  to  1855,  giving  8°  variation 
at  Fort  Snelling,  11°  at  Fort  Leavenworth,  5°  at  Alleghany  Arsenal,  and  4°. 6  at  Fort  Columbus. 
In  New  Mexico  the  range  for  the  few  years  observed  appears  to  be  large,  yet  the  observations  are  not

entirely  reliaMe  at  Fort  Fillmore  and  All)uqnerqiie,  where  the  greatest  differences  of  ^(}°  and  5°.1 
occur,  the  extreme  years  heing  1852  and  1855. 

In  the  lower  portions  of  Texas  and  Florida — districts  approaching  tropical  temperatures — the 
former  gives  a  range  of  4°, 5  at  two  or  three  posts — Fort  Mcintosh  and  Kinggold  Barracks — for  the 
last  six  years,  and  the  latter  a  much  less  range,  or  hut  1°.5  in  tlie  latitude  of  Fort  Brooke,  and  hut  2° 
at  Key  West.  At  two  or  three  posts  in  Florida  a  sufficiently  extended  series  of  years  has  been 
observed  to  give  the  probable  extremes  of  the  spring  temperature  there,  and  from  these  1838  and 
1843  appear  to  have  given  the  lowest  temperatures,  which  were  4°, 5  below  the  mean  at  Fort  Marion, 
3°.5  at  Fort  Brooke,  and  2°.l  at  Key  "West.  The  highest  were  in  1826  at  the  first  two  localities, 
and  in  1854  at  Key  West,  the  differences  being  5°, 8,  3°. 6,  and  1°.8  respectively.  The  range  in 
Northern  Florida  and  Texas  shows  a  measure  of  variability  in  the  spring  temperatures  which 
identifies  these  districts  with  those  having  continental  climates,  notwithstanding  their  high 
temperature. 

The  range  of  the  mean  temperatures  of  single  months  is  much  greater  than  might  be  anticipated 
from  the  measures  just  given,  and  two  or  three  representative  stations  may  be  cited  which  will 
sufficiently  show  what  it  is.  At  West  Point  the  range  for  March  is  20°  between  1842  and  1843,  at 
Watervliet  17°  for  the  same  dates,  at  Alleghany  Arsenal  20°. "J,  at  Detroit  22°. 5,  at  Fort  Brady 
18°. 1,  at  Fort  Crawford  25°. 7,  and  at  Fort  Snelling  34°. 5 — in  each  series  here  cited  these  years 
presenting  both  extremes  in  much  greater  degree  than  any  others  observed.  In  lower  latitudes  Fort 
Monroe  gives  20°. 1  as  the  variation  for  the  same  dates.  Fort  Marion  14°. 6,  Mount  Vernon  Arsenal 
18°. 9,  New  Orleans  19°.3,  Fort  Towson  26°.l,  Fort  G-ibson  23°,  and  St.  Louis  33°. 2.  In  lower 
Florida,  Fort  Brooke  gives  10°. 3,  but  Key  West  unfortunately  was  not  observed.  In  nearly  all  the 
tables  of  the  longer  periods  the  years  1842  and  1843  give  the  extreme  measures  of  the  series,  and 
the  highest  measure  is  generally  at  the  mean  temperature  of  the  next  month,  April,  while  the 
lowest,  in  1843,  is  several  degrees  below  the  mean  of  January  in  every  case.  This  is  an  instance  of 
the  oscillations  characteristic  of  American  temperature  range,  where  the  extreme  depressions  go 
much  farther  below  the  averages  than  the  extreme  heats  rise  above  them— the  fall  of  temperature  in 
the  present  case  at  Fort  Snelling  being  26°, 8,  while  the  excess  of  the  warm  extreme  was  but  7°. 7. 
For  several  posts  near  Fort  Snelling  the  absolute  mean  for  1843  was  but  two  or  three  degrees  above 
the  lowest  temperatures  of  any  winter  month. 

The  range  of  mean  temperature  in  April  and  May  is  much  less,  that  for  April  at  Fort  Snelling 
being  22°,  or  eleven  degrees  below  in  1850,  and  eleven  above  in  1839.  At  Fort  Leavenworth  the 
same  dates  give  18°, 5  of  range,  at  Fort  Howard  15°,  Alleghany  Arsenal  15°,  West  Point  12°,  and 
Fort  Sullivan  10°.  The  variability  remains  large,  however,  at  southern  posts;  at  Fort  Monroe  12°, 
St.  Augustine  10°,  Fort  Brooke  6°,  and  New  Orleans  7°. 5,  There  are  no  conspicuous  years  giving 
extremes  which  extend  over  the  whole  area. 

The  following  table  will  give  a  sufficient  number  of  these  citations  in  tabular  form  to  enable 
any  one  to  recognize  the  principal  features  of  this  division  of  temperature  disti-ibution.

From  this  taHe  it  will  te  seen  that  the  range  of  variability  is  somewhat  greater  than  the  differ- 
ences of  successive  months  on  the  whole,  though  if  the  single  extreme  of  March,  1843,  were  removed 
there  would  he  great  uniformity  in  these  two  measures  of  variation. 

The  measures  of  variability  at  any  point  of  a  large  area  in  a  series  of  years,  may  he  derived  from 
the  mean  of  several  stations,  and  we  find  fifteen  posts  on  the  Atlantic  coast  to  give  seven  and  a  half 
degrees  as  the  greatest  change  to  which  this  district,  as  a  whole,  has  been  subjected.  The  same 
process  gives  for  the  interior,  including  the  Lake  district  and  the  southwest,  twenty-four  stations,  a 
mean  of  nine  and  two-tenths  degrees  of  range.  The  area  of  greatest  variability  near  the  Upper 
Mississippi  gives,  from  seven  stations,  fourteen  and  eight-tenths  degrees. 

In  all  forme  of  this  comparison  these  measures  are  very  large,  applied  as  they  are  to  the  mean 
of  a  period  of  ninety  days,  and  they  indicate  the  great  importance  which  the  law  of  non-periodic 
variations  of  temperature  has  in  this  climate. 

The  average  variability,  derived  from  the  mean  of  the  departures  in  both  directions,  is  also  an 
important  phase,  particularly  at  these  months.  It  is  the  change  which  may  be  expected  in  every 
year;  and  the  following  selection  of  three  principal  series  will  give,  in  the  same  connection,  the

REPORT.  697 

From  this  tahlc  it  ■will  be  seen  that  tlie  oscillations  aie  almost  constant,  and  that  very  few 
instances  of  small  departure  occur.  The  constant  oscillation  at  Fort  Snellingj  for  March,  is  4°. 7; 
at  Fort  Gibson,  3°.2'i';  and  at  Fort  Oolumhns,  2°. 3,  It  diminjehes  through  the  other  months,  and 
for  the  whole  period  is  scarcely  two-thirds  of  the  average  of  the  single  months.  This  indicates  that 
the  quantities  extingnished  in  obtaining  the  mean  of  the  three  months,  or  the  compensating 
qnantities,  constitute  but  a  third  of  those  considered,  and  that  the  variations,  either  in  time  or  in 
degree,  cover  two-thirds  of  the  period,  or  influence  two-thirds  of  its  measure  of  heat.  This  fact  also 
demonstrates  the  truth  of  the  suggestion  elsewhere  made,  that  the  period  we  designate  as  Spring  is, 
on  the  whole,  too  long  for  identification  as  a  single  quantity  in  the  continental  temperate  regions  of 
this  hemisphere.  The  natural  seasons  are  unequally  divided  in  time,  in  truth,  the  winter  and 
summer  being  longer,  and  the  spring  and  autumn  being  shorter  than  ninety  days.* 

The  remaining  feature  of  this  variability  is  the  range  of  single  observations  through  these 
months,  and  particularly  through  April  and  May.  Ajo.  analysis  which  would  give  the  mean  position 
of  these  single  extremes  for  every  year,  and  the  absolute  position  of  each,  as  selected  from  the  whole 
series,  would  best  express  the  more  desirable  form  of  the  result.  Thus  it  is  important  to  know  to 
what  degree  we  may  expect  the  temperature  to  fall,  at  any  single  observation,  in  each  of  the  spi-ing 
months,  in  the  several  districts,  or  the  mean  of  the  minima  and  maxima,  and,  also,  to  know  what  is 
the  very  highest  and  very  lowest  point  possible  to  be  attained  in  a  series  of  years.  The  line  of  32°, 
as  a  minimum  for  each  month,  is  also  quite  necessary  in  a  practical  climatology. 

The  last  point,  or  the  district.3  in  which  the  thermometer  generally  falls  to  near  the  freezing 
point  once  or  more  in  the  course  of  the  month,  may  be  readily  defined  without  a  tabular  statement. 

On  the  coast  of  California  an  examination  of  the  minima  for  five  years  affords  but  two  instances 
of  the  observation  of  32°  in  March ;  while  in  the  interior,  and  in  Oregon,  it  may  be  anticipated 
several  times  in  this  month,  though  the  lowest  observed  point  at  stations  not  much  elevated  is  19°. 
In  April  it  is  never  reached  in  California  at  the  sea  level,  or  near  it,  and  rarely  in  Oregon — at 
Puget's  Sound  three  times  in  six  years.  In  May  there  are  no  instances  of  its  occurrence  on  tho 
Pacific  coast,  except  at  stations  elevated  two  thousand  feet,  or  more. 

At  Fort  Yuma,  in  the  valley  of  the  Colorado,  the  freezing  point  never  is  reached  in  spring. 
At  all  the  stations  of  New  Mexico  the  temperature  constantly  falls  below  32°  in  every  month  of 
spring,  and  at  Fort  Massachusetts  and  Fort  Defiance  it  usually  does  so  in  June. 

In  Texas  there  is  no  frost  or  ice  in  the  lower  Eio  Grande  valley  in  these  months,  though  it  twice 
occurs  at  Fort  Duncan,  and  the  posts  of  that  vicinity,  in  March.  Perhaps  a  more  extended  series  of 
years  would  give  instances  of  severe  frost  in  the  principal  portion  of  this  valley  in  March,  though 
there  could  be  none  in  the  following  months.  All  the  remaining  portion  of  Texas  has  the  occurrence 
of  frosts  in  March  regularly  ;  in  April,  for  the  lower  districts,  very  rarely,  though  they  occur  in  half 
the  years,  or  more,  at  the  posts  on  the  plateaux  elevated  one  thousand  to  two  thousand  feet ;  but 
never  in  May  at  any  point  not  mountainous. 

In  the  principal  area  of  the  United  States  eastward,  the  lower  portion  of  the  peninsula  of  Florida, 
below  Fort  Brooke  is  tho  only  portion  not  liable  to  frosts  in  March  in  extreme  years.     From  the  year 

*  An  admirable  analysis  of  ten  years'  observationa at  Albion  Mines,  Nova  Scotia,  has  been  made  by  their  author,  Henry  Poole,  esq., 
by  which  it  appears  that  the  seasons  there  are  naturally  resolved  into  periods  of  66  and  63  days  for  spring  and  autumn,  and  120  and 
116  days  for  winter  and  summer.  The  winter  minimum  temperaturo  is  January  20th,  or  ttiirty  days  after  the  Boletioo,  and  tho  summer 
maxunum,  July  22d,  or  thirty-one  days  after  the  solstice.  The  mean  anntial  temperature  is  passed  on  May  Isl  and  November  4th, 
forty-one  and  forty -four  days  alYer  the  equinoies,  reapectively.

698  REPORT. 

1822,  when  otservations  were  either  at  that  district  oi-  eo  near  it  as  to  decide  the  point,  twelve  years 
occur  in  which  the  thermometer  fell  to  32°  6c  lower  as  far  south  as  Fort  King,  and  in  two  of  these 
years  at  least,  1835  and  1843,  it  fell  to  the  freezing  point  as  far  southward  as  Fort  Brooke.  In 
something  more  than  half  the  years  of  the  period  now  observed,  the  coast  of  the  Gulf  and  of  the 
Atlantic  to  Charleston  experiences  one  or  more  instances  of  a  temperature  of  32*^  in  this  month. 

In  April  the  line  of  ice  and  frosts,  or  a  temperatures  at  or  near  32°,*  recedes  to  Fort  Monroe  and 
Fort  Gibson,  and  they  are  much  more  rare  at  either  of  these  posts  than  at  ^Florida  stations  in  March. 
The  depressions  of  temperature  in  which  they  occur  are,  however,  frequently  connected  with  falls  of 
enow  in  the  Atlantic  States,  and  they  usually  affect  the  more  elevated  portions  of  all  the  States  east 
of  Alabama.  In  1854  a  heavy  fall  of  snow  occurred  at  the  middle  of  the  month  in  Virginia,  and  ice 
was  ibrmcd  in  the  vicinity  of  Charleston,  South  Carolina,  Though  frosts  are  quite  frequent  in  this 
month  at  St.  Louis,  there  are  few  instances  of  the  formation  of  ice  in  the  latitude  of  Fort  Gihson  ; 
light  hoar  frosts  occur  in  almost  every  year,  however,  and  sometimes  as  far  southward  as  Baton  Eouge. 
These  may  occur  at  an  air  temperature  of  43°  in  the  ordinary  positions  of  the  thermometer. 

In  May  the  line  of  ice  formation  rises  to  St,  Louis,  Newport  barracks,  (Cincinnati,)  Fort  Miflin, 
(Philadelphia,)  and  the  posts  of  New  York  harbor,  and  at  these  points  the  temperature  of  32°  is  not 
found  in  every  year.  Ice  is  formed  during  the  first  half  of  the  month  to  this  latitude  in  the  interior 
districts,  however,  quite  regularly,  and  hoar  frosts  occur  in  the  remainder  where  the  altitude  is 
noticeable  and  at  some  distance  from  the  coast.  At  the  close  of  this  month  frosts  disappear  from  all 
portions  of  the  United  States  territory,  except  at  the  highest  altitudes  cultivated.  In  connection  with

DISTRIBUTION  OF  TEMPER  A  TUBE  FOE  THE  THREE  MONTHS  OF  SUMMER. 


Thb  chief  points  of  difference  between  the  temperature  distribution  of  the  two  continents  of  the 
northern  hemisphere  appear  in  the  summer  more  decidedly  than  at  any  other  season,  and  distinguish 
the  isothermal  illustration  for  this  season  by  some  extreme  and  apparently  inexplicable  curvatures. 
The  difticulty  of  illustrating  this  distribution  is  increased  by  taking  the  actual  superficial  distribution 
of  heat  as  the  principle  on  which  the  chart  is  constructed,  because  of  the  great  altitude  of  the  plains 
and  mountainous  districts  of  the  interior  and  western  portions  of  the  continent.  These  plains  and 
plateaux  are  generally  characterized  by  very  high  summer  temperatures  also,  and  in  the  detailed 
examination  and  comparison  of  these  districts,  these  altitudes,  and  the  particular  problem  of  vertical 
distribution  of  heat  will  require  some  notice. 

Generally  the  summer  temperatures  show  a  great  change  from  those  of  the  winter  months,  and  the 
interior  areas  which  are  but  little  elevated  above  the  sea  exhibit  almost  or  quite  unparalleled  measures 
of  heat.  These  warmer  portions  exceed  even  the  tropical  districts  of  the  continent  in  mean  tempe- 
ratures for  these  months,  and  they  still  more  exceed  those  of  the  adjacent  seas  on  the  south.  The 
mean  surface  temperature  of  the  Gulf  of  Mexico,  and  of  the  coasts  of  all  parts  where  the  trade  wind 
and  sea  breeze  and  the  tropical  rains  prevent  any  accession  from  the  radiation  of  land  surfaces, 
appears  to  be  Tery  nearly  at  the  mean  of  eighty  degrees  for  the  summer ;  and  the  West  India  islands 
generally,  at  positions  with  the  usual  land  surface  exposures,  at  a  mean  of  eighty-one  and  a  half  and 
eighty-two  degrees  for  the  same  months.*  On  the  tropical  coasts,  where  the  rainy  season  is  most 
perfectly  developed  in  summer,  and  continues  most  uniformly,  as  on  the  coasts  and  islands  of  Granada 
and  the  isthmus  of  Panama,  the  mean  is  still  lower,  and  often  as  low  as  78°  for  July. 

The  districts  distinguished  by  these  extra-tropical  temperatures  in  the  United  States  embrace  the 
dry  interior  of  Florida,  which  has  a  mean  of  eighty-two  degrees  or  more  for  the  summer,  and  a  large 

*  The  results  of  several  aeriea  of  observations  in  the  West  India  islands  correspond  strikingly  in  the  measures  of  mean  temperature 
for  the  summer  where  tiie  conditions  of  oxposuto  are  alike,  aa  tile  following  citations  show  :

The  average  temperatuve  of  the  surface  waters  of  the  Gulf,  as  recorded  in  Maury's  charts,  is  one  authority  for  deduction  of  the 
air  temperature.  The  following  records  confirm  the  assumed  distribution:  At  Tortola,  W.  I.,  9  years,  60.6  degrees;  at  Batbadoes,  I 
year,  79.5  degrees,  from  Dove;  at  Caracas,  one  year,  74.4  degrees,  from  Kaemti ;  at  Vera  Cruz,  one  year,  80.2  degrees,  United  States 
Army  Meteorological  Register,  1847.  And  generally  the  results  at  coast  stations  of  the  Gulf,  as  Cedar  Keys,  Fort  Morgan,  Camp 
Sabine,  &G. 

By  many  comparisons,  Humboldt  detormines  the  mean  temperature  of  the  sea  to  be  greater  than  that  of  the  air  above  it,  between 
the  equator  and  48°  of  north  and  south  latitude,  (Pera.  Nar.,  vol.  vii,  p.  434.)  This  is  doubtless  more  uniformly  tho  case  in  the 
Atlantic  than  in  the  enclosed  seas  of  tho  West  Indies  ;  and  it  Is  remarked  by  Humboldt,  indeed,  who  gives  as  the  mean  annual  tem- 
perature of  the  West  Indian  sea  79.6  degrees,  with  89.3  degrees  for  the  hottest  season,  (in  February  and  March,)  and  77  degrees  for 
tlie  coldest,  which  is  in  November  and  December.  The  summer  oi  the  north  temperate  ioiie  would  give  little  more  than  80O  for  tlic 
water  temperature,  and  it  could  not  be  placed  above  80°  for  tlje  air. — {Ibid,  p.  410.)

area  beginning  near  Savannah  on  the  east,  and  extending  through  the  whole  low  country  of  the  Gulf 
States  westward  to  the  Bio  Grande.  In  Texas  this  helt  is  much  enlarged,  and  it  herders  on  and 
embraces  a  large  district  in  the  valley  of  the  lower  Bio  Grande,  where  the  sumnier  mean  temperature 
exceeds  eighty-five  degrees.  In  the  upper  valley  of  the  Rio  Grande  they  again  appear,  notwithstand- 
ing the  increased  altitude  of  three  thousand  five  hundred  feet,  on  the  Mexican  side  at  the  Bolson  de 
Mapimi,  and  in  the  valley  at  Presidio  del  Norte,  as  at  several  points  in  the  more  narrow  valley  on  the 
north  side  of  the  Rio  Grande  below  and  at  El  Paso.  The  valley  of  tlie  Colorado  river  of  California  is 
the  district  of  greatest  excess,  however,  the  summer  mean  here  reaching  ninety  degrees.  A  consider- 
able portion  of  the  desert  bordering  this  river  on  the  west  doubtless  is  quite  the  same  as  the  military 
position  at  Fort  Yuma,  though  no  other  part  has  been  observed.  West  of  the  Sierra  Nevada  another 
district  of  extra-tropical  temperatures  exists,  in  tlie  San  Joaquin  valley,  represented  by  Fort  Miller,  at 
which  post  the  mean  summer  temperature  for  three  years  is  eighty-five  and  a  half  degrees. 

The  lower  valley  of  the  Colorado  has  few  parallels  in  temperate  latitudes  in  its  measure  of  meaji 
temperature,  if,  indeed,  a  parallel  in  the  same  latitudes  may  anywhere  be  found.*  But  this  and  the 
other  last-mentioned  extreme  di8trict.s  are  still  more  remarkable  for  the  single  extremes  observed  in 
these  months,  and  in  the  mean  temperature  at  the  extreme  hour  of  3  p.  m.  At  Ringgold  barracks,  in 
the  Eio  Grande  valley,  the  mean  of  tbe  observations  at  3  p.  m.  for  the  entire  three  summer  months  of 
1850  is  one  hundred  and  one  and  two-tenths  degrees,  (101°. 2,)  and  the  single  extremes  reach  one 
hundred  and  seven  degrees  for  each  month.  Other  stations  in  the  same  district  give  results  so  near 
to  these  that  no  considerable  error  of  the  instrument  may  be  supposed  to  exist.  In  1851  the  measures 
for  the  same  dates  are  but  two  or  three  degrees  less  in  the  means,  and  quite  as  great  in  the  single 
readings  at  these  posts,  and  in  1852  and  1853  they  are  very  little  different  from,  and  on  the  whole  as 
great  as  those  of  1851.  Still  higher  single  readings  are  recorded  in  the  Colorado  and  San  Joaquin 
vaUeys  of  California,  at  Forts  Yuma  and  Miller,  the  highest  being  121°  at  Fort  Miller,  in  July,  1853, 
and  116°  at  Fort  Tuma,  in  June  of  the  same  year.  The  highest  monthly  mean  for  any  hour  is  that 
at  Fort  Miller,  for  June,  1852,  of  108°, 4,  at  3  p.  m.,  with  a  single  maximum  reading  of  116°. 
There  are  frequent  instances  of  a  mean  temperature  for  a  summer  month  exceeding  one  hundred 
degrees  at  3  p.  M.,  one  of  which  occurred  at  Fort  Gibson  in  August,  1834,  and  many  within  the  five 
years  of  observation  in  Texas,  New  Mexico,  and  California. 

The  concurrence  of  so  many  records  establishes  the  position  that  the  summer  temperatures  of 
several  districts  in  the  temperate  latitudes  of  this  continent  largely  exceed  those  measures  in  its 
humid  tropical  climates,  at  least,  if  they  are  not  quite  unparalleled  at  any  point. f     As  these  appear 

*  In  the  collection  of  temperature  tables  by  DovE  some  stations  in  India  and  Persia  are  given  with  sBry  high  temporaturee,  yet  the 
periods  are  short,  and  some  doubt  rests  on  the  adaptation  of  the  hours  to  give  the  true  mean.  At  Bagdad,  Bassora,  and  Abusherehr, 
Persia,  observations  are  recorded  giving  92^^  and  930  for  the  mean  of  summer,  but  no  mention  is  made  of  the  hours  of  observation.  At 
many  poinla  in  India  the  months  of  May  and  June  ejthibit  excessive  heats,  but  the  summer  is  usually  a  rainy  season,  and  of  a  very  large 
number  of  stations  given  by  DovE  but  one  Pondicherry,  exceeds  9(P  for  the  summer  mean.  This  is  at  11°  56'  north  latitude,  itR  summer 
mean  for  one  year  930.7.  ArabaJa  n  a  Dell  latitude  30°  25',  has  a  moan  of  100°  for  May  and  96°  for  June;  Cawnporo,  latitude 
36O30',95O.5forMaj,  &c.  Tins  ae  B  t  sh  bsorvations,  and  their  great  number  for  India  probably  reprBsents  all  districts  where

at  several  points  of  districts  generally  similar,  and  in  successive  years  at  the  samo  points,  no 
coneideraMe  errors  of  the  instruments  may  te  apprehended,  and  none  can  exist  which  vitiate 
comparison  with  the  records  of  other  climates  generally.  The  instmments  were,  indeed,  all 
carefnlly  constructed  and  carefully  compared. 

In  this  general  view  of  the  temperature  distribution,  there  are  one  or  two  anomalous  instances 
of  refrigeration  of  the  summer  temperature  which  render  the  explanation  of  the  facts  of  great 
interior  heat  more  difficult  than  they  would  be  otherwise.  The  greatest  diminution  of  the  summer 
heat  is  on  the  coast  of  the  Pacific,  and  the  contrast  of  that  district  with  those  in  which  the  great 
extremes  of  heat  have  been  recorded  is  moat  extraordinary.  Fort  Miller  in  the  San  Joaquin  valley 
of  California  is  less  than  one  hundred  and  fifty  miles  due  eastward  from  the  coast  of  the  Pacific  at 
Monterey,  where  the  mean  summer  temperature  falls  off  to  57°.  For  the  month  of  June,  1852,  the 
mean  of  108°. 4  at  3  p,  M,,  at  Fort  Miller,  had  a  corresponding  mean  at  Monterey  of  63°. 2,  and  a 
single  maximum  there  of  70° — a  difference  in  the  means  of  forty-five,  and  in  the  extremes  of  forty- 
six  degrees.     The  difference  in  the  complete  monthly  means  was  thirty  degrees. 

The  measures  of  difference  and  contrast  here  given,  are  also  in  a  great  degree  characteristic  of 
large  districts ;  as  the  cold  of  the  coast  of  the  Pacific  in  summer  extends  over  twenty  degrees  of 
latitude,  or  from  the  fiftieth  to  the  thirtieth  parallel,  while  the  extremes  of  summer  heat  are  common 
to  all  the  valleys  and  basins  of  the  western  portion  of  the  continent,  where  a  single  range  of  moun- 
tains intervenes  between  them  and  the  Pacific  coast.  The  summer  isothermal  of  57**  will  be  seen  to 
extend  along  the  coast  from  Sitha,  in  Russian  America,  to  Monterey,  giving  an  almost  absolutely 
equal  temperature  for  this  extensive  line  of  fifteen  hundred  miles  of  latitude,  and  near  two  thousand 
miles  of  coast,  A  portion  of  the  coast  of  Oregon  has  temperatures  noticably  higher,  for  the  brief 
period  of  the  record  there,  which  may,  perhaps,  prove  the  position  of  the  cold  line  to  be  a  little 
distance  off  that  coast  at  sea- 

The  Atlantic  coast  furnishes  another  instance  of  depression  of  temperature,  from  causes  not 
common  to  all  changes  of  seasons  on  the  ocean  coasts.  The  sea  winds  and  mists  are  here  noticahly 
colder  than  the  average  temperature  of  the  sea  itself,  at  any  considerable  distance,  and  exposures  open 
to  these  have  a  temperature  perceptibly  reduced  as  far  southward  as  Florida.  As  the  positions  of  the 
isothermals  of  five  degrees  of  difference  are  widely  separated  in  summer,  and  as  each,  therefore, 
approximately  represents  a  large  district,  in  which  it  may  change  position  considerably  for  slight 
positive  differences,  the  curvature  for  the  lines,  as  drawn,  gives  a  somewhat  undue  impression  of 
these  changes,  and  of  the  cooling  effects  of  the  coast  positions.  The  lines,  also,  double  on  themselves 
abruptly  to  follow  the  warm  atmosphere  of  the  Gulf  stream.  The  cause  of  this  refrigeration  is  found 
in  the  cold  masses  of  water  present  on  the  northern  parts  of  the  coast,  or  returning  in  currents  next 
the  Gulf  stream^  and  beneath  it.  The  existence  of  this  current  beneath  is  fully  shown  by  the  Coast 
Survey  observations,  and  the  fact,  first  noticed  by  Humboldt,*  that  deep  lying  masses  of  cold  water 
may  be  pressed  against  shelving  coasts  by  great  ocean  currents,  and  thus  be  brought  to  the  surface, 
cooling  the  immediate  coast  more  than  any  other  point  in  its  vicinity,  appears  to  go  far 
towards  solving  the  problem  of  the  presence  of  these  cold  waters,  where  no  surface  current  is  percepti- 
ble.    For  most  parts  of  the  Atlantic  coast  these  causes  are  sufficient  only  to  affect  the  winds  from  the 

of  the  African  Desert — Nabia,  and  Arabia — is  embraced  by  an  isolhermn,!  of  90O.5.  The  mean  of  tliis  montli  for  three  years  at  ITort 
Yuma  is  930,27,  and  for  two  auecessive  years  it  exceeds  94°,  It  cannot  be  of  less  mens,  lemperatuve,  therefore,  lliough  but  a  point 
in  comparison  to  the  great  Nubian  and  Arabian  Desert,  for  the  singlo  month  of  July,  or  the  mean  of  the  tliree  months  of  summer.

northeast,  whjcli  ie  the  direction  covering  the  largest  water  surface  of  this  character,  and  the  summer 
temperatures  are  reduced  hy  the  effect  of  these  alternations,  without  the  production  of  a  decided  single 
extreme,  and  without  the  uniformity  which  characterizes  the  refrigerating  winds  of  the  Pacific.  The 
phenomenon  is  sufficiently  well  known,  yet  it  is  not  so  decidedly  associated  as  it  should  be  with  these 
cold,  deep  sea  currents,  and  the  masses  of  cool  water  of  the  coasts.*  It  is  difficult  to  illustrate  this 
feature  hy  citation  of  measures  of  temperature,  as  the  depressions  appear  in  the  form  of  two  or  three 
days  of  generally  low  temperature,  without  reaching  a  single  minimum  so  low  as  might  he  attained 
at  an  interior  station  from  the  eifect  of  radiation  alone. 

The  Gulf  Stream  is  somewhat  ahore  the  mean  temperatures  of  the  east  coast  of  tlie  continent  in 
the  same  latitudes,  even  in  summer,  and  the  isothermals  would  curve  northward  rather  than  south- 
ward in  their  extension  at  sea,  if  no  influences  other  than  that  stream  or  the  undisturbed  sea  were 
encountered.  There  is,  however,  no  point  of  the  coast  at  which  the  temperatures  of  summer  are 
greater  for  the  existence  of  the  Gulf  stream,  as  the  continental  influences  everywhere  predominate 
under  the  prevalence  and  controling  character  of  the  westerly  winds.  The  same  atmospheric  circula- 
tion carries  the  heated  waters  and  their  accompanying  local  atmosphere  to  the  European  coasts ;  yet 
there  the  temperature  becomes  reduced  by  diffusion  over  tlie  sea,  and  the  high  proportion  of  moisture 
cools  the  summer  climates  rather  than  otherwise.  This  is  shown  by  comparing  the  high  temperatures 
of  our  dry  western  interior  with  those  of  western  Europe. 

The  cold  climates  of  the  Pacific  coast  in  summer  constitute  a  general  phenomenou  of  temperature 
distribution  more  difficult  of  explanation  than  any  other,  as  the  degree  of  refrigeration  is  so  very  great, 
and  the  contrast  with  interior  districts  so  extreme  over  many  degrees  of  latitude.  The  striking 
uniformity  in  the  measures  of  mean  temperature  here,  which  has  been  alluded  to  as  characterizing 
nearly  all  the  observed  points,  is  conclusive  evidence  of  the  existence  of  some  general  and  powerful 
agency  other  than  the  immediate  one  of  cold  day  winds.  The  analogies  of  the  coasts  of  South 
America,  Africa,  and  the  north  Atlantic  would  indicate  at  once  a  reference  to  great  polar  currents, 
and  to  the  transfer  of  large  masses  of  cold  waters  from  the  northern  parts  of  the  Pacific,  but  the 
ordinary  sea  observations  have  hitherto  failed  to  discover  any  regular  or  marked  currents  here. 
Northward  and  westward  from  San  Francisco  the  surface  currents  appear  as  freq^uently  from  one  point 
as  another  on  llaury's  charts,  though  the  existence  of  a  general  movement  from  the  northwest  is 
recognized.  There  is  apparently  a  deep-sea  current  from  that  direction  of  great  magnitude  and 
volume,  which  appears  only  by  the  lifting  of  its  waters  on  approaching  the  coast,  and  in  the  general 
refrigeration  of  the  waters  of  the  whole  area,  with  the  conaecLuent  effect  on  the  sea-winds  and  on  the 
climate  of  the  land.  The  water  temperatures  noted  in  the  summer  months  are  less  than  those  of 
winter,  and  their  mean  is  nearly  57°,  or  that  of  the  sea  winds  and  of  the  summer  on  the  coast.  The 
body  of  water  so  affected  is  shown  by  Maury's  charts  to  extend  north-westwardly  toward  the  peninsula 
of  Alaska,  and  to  he  strikingly  uniform  in  its  characteristics  of  low  temperature,  absence  of  sm-face- 
currents,  and  continuous  northwest  winds,  so  far  as  observed. f     This  great  mass  of  cold  waters,  and

to  fifty-four  degrees,  while  in  the  Gulf  stream  it  whb  at  seveaty  degrees,  and  in  the  open  sea  beyond  sixty-six  and  a.  half  degrees  ;  the 
air  temperature  on  the  hanks,  at  noon,  being  fifly-eight  to  sixty  degrees.  He  also  notices  the  refrigeration  of  land  elimates  near  these 
masses,  neoesarily  resulting  from  their  presence, 

f  The  temparatufBS  of  the  cold  currents  of  the  Pacific  coast  of  South  America  are  very  nearly  tho  same  as  those  observod  hare,  even

Its  atteniijHit  cold  surface  atmosplicre,  develops  a  strong  eea  wind  towards  the  greatly  heated  and 
rarified  interior  valleys  and  plains ;  and  where  these  contrasts  of  temperature  are  greatest,  the  maxi- 
mum effect  is  produced,  as  at  San  Francisco  and  Monterey.  It  is  not  strange,  therefore,  that  the 
immediate  coast  is  cooled  to  the  temperature  of  the  air  and  water  of  so  large  a  portion  of  the  ocean. 

As  the  solution  of  this  great  depression  of  coast  temperatures  is  evidently  found  in  the  tempera- 
ture of  the  Pacilic  ocean,  it  may  serve  to  confirm  the  accuracy  of  the  observations  there  to  give 
the  mean  of  such  observations  as  have  been  recorded  at  sea.  Taking  the  observations  in  Maury's 
Wind  and  Current  charts  for  these  portions  of  the  Pacific,  in  means  for  areas  of  five  degrees  of 
latitude  and  longitude,  we  find  the  areas  westward  of  San  Francisco  to  give  56°. 5,  62°. 3,  64°. 4, 
and  68°,  successively.  The  areas  next  southward,  or  between  30°  and  35°  of  latitude,  decrease  in 
temperature  westward  from  longitude  120°,  by  the  successive  numbers  of  60°. 5,  63°. 3,  65°. T,  and 
66°.'?,  to  the  meridian  of  140°.  South  of  the  parallel  of  30°  there  are  no  summer  observations  on 
the  coast.  In  the  latitude  of  the  Sandwich  Islands  (20°  to  25°)  the  temperatures  increase  from  72°, 
at  the  meridian  of  120°,  to  77°  at  150°  in  the  vicinity  of  those  islands. 

The  contrasts  which  induce  these  violent  sea  winds  exist  only  in  the  summer  months,  including 
May  and  September,  as  at  other  seasons  the  ocean  is  quite  as  warm  and  the  land  colder,  and,  what- 
ever the  degree  of  aridity,  the  sudden  and  extreme  rarefactions  do  not  occur  in  the  interior.  As  this 
unusual  circulation  ceases  the  temperature  rises,  and  the  spring  and  autumn  are  both  warmer  than 
the  summer,  on  the  immediate  coast,  over  a  space  embracing  several  degrees  of  latitude. 

It  may  appear  inexplicable  that  the  northern  districts  of  this  coast,  to  fifty-seven  degrees  north 
latitiide,  should  he  ecLual,  if  not  higher  in  temperature  than  that  at  San  Francisco  ;  but  the  refriger- 
ating current  appears  to  originate  westward  of  Alaska,  and  to  pass  nearly  due  southeast  from  that 
point  toward  the  continent  in  the  latitude  of  Monterey  ;  not  entering  the  indentations  of  the  Russian 
and  British  American  coasts,  probably,  in  any  degree,*  There,  may,  also,  be  warm  waters  flowing 
over  these  from  the  central  areas  of  the  Pacific,  from  a  division  of  the  great  warm  currents  of  the 
Asiatic  coast,  and  producing  the  general  effect  on  the  Pacific  climates  which  tho  Gulf  stream 
produces  on  those  of  Europe.  Such  is  clearly  the  case  in  winter,  when  those  movements  outrank 
those  from  the  Polar  seas  and  give  high  temperatures  for  the  whole  mass  of  the  pEicific,  even  where 
the  cold  waters  are  most  marked  in  summer. 

These  comparisons  are  indispensable  to  show  the  reliability  of  the  temperature  measures  given 
at  Pacific  stations,  and  that  this  anomalous  arrangement  of  the  isotherraals  is  a  correct  represen- 
tation. This  arrangement  is  also  independent  of  all  considerations  of  altitude,  as  the  construction  of 
sea  level  isothermals  for  the  interior  would  hut  increase  the  contrasts,  and  the  coast  stations  are  all 
at  sea  level. 

In  a  more  detailed  explanation  of  the  interior  temperature  distribution  for  the  summer  a  com- 
parison of  the  successive  districts  may  be  made,  comnaenciug  with  those  of  the  east. 

In  the  New  England  States  there  are  several  points  where  the  climates  are  principally  marine.

704  RE  POET. 

I'orts  Sullivan,  Independence,  and  Adams  are  particularly  so,  and  we  find  at  tliese  a  perceptible 
falling  off  from  tlie  high  temperatures  of  other  posts,  especially  in  the  maxima  and  in  the  range  of 
summer  temperature.  Fort  Snllivan  has  the  same  temperatures  as  the  posts  on  the  upper  part  of  the 
St.  John's  river,  at  the  extreme  northern  point  of  Maine,  and  two  hundred  miles  from  the  coast. 
The  altitude  of  this  interior  district  is  not  very  great,  and  the  proximity  of  the  St.  Lawrence  valley 
favors  the  development  of  the  comparatively  warm  summer  which  is  found  along  the  line  from  the 
mouth  of  the  St.  John's  river  to  Quehec.  The  interior  rises  so  much  southward  that  no  line  of 
warmer  temperatures  appears  until  the  plains  near  Montreal  are  reached,  the  vicinity  of  Lake  Cham- 
plain  in  Vermont,  the  valley  of  the  Connecticut  river,  and  the  southwest  point  of  Maine,  at  Portland 
and  Fort  Prehle.  The  line  of  65°  which  passes  here  is  sometimes  found  for  several  successive  years  in 
the  valley  of  the  St.  John's,  which  has  a  general  mean  of  63°.  The  isothermal  of  65°  may  also  be 
extended  in  the  low  country  of  Maine  as  far  as  Bangor,  returning  along  the  coast  nearly  to  Fort 
Constitution,  (Portsmouth,)  New  Hampshire.  Next  a  portion  of  southern  Maine,  New  Hampshire, 
and  Vermont,  the  valley  of  Lake  Charaplain,  and  the  vicinity  of  Montreal  may  be  correctly  repre- 
sented by  the  mean  of  67°. 5 ;  and  the  general  features,  apart  from  the  mean,  are  quite  alike  for  these 
districts — all  being  interior  climates,  with  a  large  range  of  single  extremes  and  of  extremes  in  consecu- 
tive years.  This  measure  is  common  to  still  more  extensive  districts,  as  it  embraces  nearly  all  of 
Massachusetts  and  of  New  York,  with  northern  Pennsylvania,  Michigan,  and  "Wisconsin.  The  greater 
elevations  of  southern  New  England,  New  York,  and  northern  Pennsylvania  make  up  for  the 
difference  of  latitude,  and  as  the  general  average  of  surface  temperatures  is  necessarily  considered  here 
the  districts  enumerated  may  be  quite  identified.  In  all  this  area  the  deep  river  valleys  and  particu- 
larly arid  or  sandy  localities  are  excepted,  and  these  may  be  assigned  a  mean  temperature  of  70°  for  the 
summer.  Westward  of  Wisconsin  this  very  favorable  measure  of  temperature  only  appears  in  moun- 
tainous districts,  and  under  very  different  circumstances.  It  there,  however,  distinguishes  the  best 
portions  of  Oregon  and  California. 

Between  the  mean  of  70°,  which  appears  in  many  localities  of  the  last  general  district,  and  that 
of  75°,  there  is  a  very  large  area  embraced,  the  extreme  range  east  of  the  plains  being  from  latitude 
thirty-four  degrees  in  northern  Georgia  to  Fort  Snelling,  latitude  forty-five  degrees.  In  the  general 
phenomena  of  temperature  distribution  this  district  of  the  central  States  is  quite  uniform.  Its  single 
extremes  of  temperature  are  less  than  in  the  next  cooler  disti-ict,  yet  the  range  of  the  mean  tempera- 
ture is  quite  as  great,  or  even  greater.  Thus  the  lino  of  75°  varies  its  position  very  greatly  in 
extreme  years,  sometimes  reaching  nearly  to  Fort  Howard,  in  Wisconsin,  and  again  falling  off  to  the 
northern  line  of  Louisiana.  On  the  Atlantic  coast  it  ranges  from  New  York  city  to  central  North 
Carolina,  less  than  in  the  Mississippi  valley,  but  still  greater  than  the  range  of  the  mean  of  65°. 
This  last  has  its  greatest  range  on  a  line  of  contrasted  altitudes  from  central  Pennsylvania  to  Quebec, 
hut  in  other  positions  and  at  like  altitudes  its  range  is  hut  about  half  that  of  the  line  of  75° , 

There  is  great  identity  of  the  temperatures  of  this  large  area  embraced  hy^the  isothermals  of  70° 
and  75°  east  of  the  plains,  including  Iowa,  Illinois,  Indiana,  Ohio,  Kentucky,  Upper  Tennessee,  Virginia, 
Maryland,  Delaware,  Lower  Pennsylvania,  and  New  Jersey ; — excepting  from  these  some  points  of 
coast  exposure  and  of  the  mountainous  districts,  the  summer  temperatures  are  more  nearly  uniform 
than  almost  any  continental  area  of  like  magnitude.  The  southern  border  of  this  district  has  not 
the  exceptions  of  greater  temperature  which  belong  to  the  next  northern  class,  as  the  differences  of 
local  position  cause  much  less  difference  in  the  mean  temperatures.     The  lines  curve  only  about  tlie

altitudes  of  the  AUeghaniea,  and  but  for  these  would  have  a  very  uniforiu  direction  a  little  north  of 
west  from  the  Atlantic  coast  to  the  Mississippi  valley.  The  line  of  75°  is,  however,  as  far  north  on 
the  plains  of  New  Jersey  as  at  the  Mississippi  river. 

The  continuation  of  these  lines  over  the  plains  and  the  Pacific  districts  is  under  peculiar  circum- 
stances, ijuite  different  from  those  prevailing  at  the  east.  Moat  of  the  area  of  the  great  plains  is  em- 
braced by  them,  from  the  Llano  Estacado  of  Texas  to  the  most  northern  position  on  the  Missouri 
river.  West  of  100°  longitude  the  plains  slope  northward  rather  than  otherwise,  or  the  successive 
areas  are  more  dry  and  desert-like  on  any  right  line  east  of  the  Rocky  mountains,  as  the  south  fork 
of  the  Platte  is  more  arid  than  points  further  south  on  the  same  line.  So  from  the  sources  of  the 
Canadian  and  the  Eaton  mountains  northward ;  and  though  at  Port  Laramie  and  north  of  it  there  are 
elevations  wliich  interrupt  the  general  Rlope,  yet  north  of  these  again  the  plain,  of  the  Missouri  river 
falls  off  more  than  two  thousand  feet  on  a  line  due  north  from  Port  Laramie.  Port  Benton,  at  five 
degrees  of  longitude  further  west  and  five  and  a  half  degrees  of  latitude  iiirther  north,  is  also  1856 
feet  lower.  It  is  not  surprising,  therefore,  that  as  the  plains  are  in  every  part  particularly  liable  to 
the  accumulation  of  heat  in  summer  the  mean  temperature  of  the  northern  areas  should  be  compara- 
tively high,  and  should  somewhat  exceed  that  of  the  lake  district  and  the  Atlantic  coast.  The  lines 
of  70°  and  15°  are,  however,  very  remarkably  separated  from  that  of  80°,  and  thrown  q^uite  beyond 
what  might  have  been  anticipated  from  the  altitude  of  the  plains  and  from  the  climates  of  other  parts 
of  the  continent.  It  is  well  established  that  the  line  of  75°  reaches  to  Fort  Pierre,  on  the  Missouri, 
returning,  over  twelve  and  a  half  degrees  of  latitude,  to  the  upper  plains  of  Texas. 

Between  the  lines  of  75°  and  80°  of  mean  summer  temperature  is  another  large  area  in  the  eastern 
part  of  the  United  States,  and  also  on  the  plains.  It  most  resembles  the  district  between  the  isother- 
mals  of  70°  and  75°,  and  on  the  plains  it  is  distinguished  by  the  very  small  differences  of  its  measures 
from  80°  over  most  of  the  district — the  isothermal  of  79°  embracing  the  plains  of  the  Arkansas  for  a 
large  area. 

The  line  of  80°  is  more  uniform,  and  it  embraces  the  whole  lower  States  in  a  concentric  curvature 
with  higher  temperatures  within,  and  a  diminution  in  all  directions  toward  the  Atlantic,  the  Gulf  of 
Mexico,  and  the  Mexican  interior.  Most  of  the  area  embraced  is  tropical  in  many  of  its  features,  and 
but  for  the  winter  extremes  of  low  temperature  it  would  rank  fully  as  such.  Except  some  portions  near 
the  southern  extension  of  the  AUeghanies  and  in  western  Texas,  it  defines  the  cane  district  in  its 
possible  limits,  and  those  in  which  it  is  now  occasionally  cultivated.  As  previously  alluded  to  in  the 
general  notices  of  temperature  distribution  for  the  summer,  the  Atlantic  coast  is  colder,  notwith- 
standing the  near  position  of  the  Gulf  stream,  and  the  line  therefore  curves  down  the  coast  directly 
from  Fort  Johnston,  N.  0.,  to  Now  Smyrna,  Florida,  returning  up  the  western  coast  to  Cedar  Keys. 
At  Key  "West  there  are  evidently  local  circumstances  which  augment  the  temperature  beyond  that  of 
the  channel  between  this  point  and  Cuba — the  sand  surface  of  the  island,  small  as  it  is,  being  probably 
sufficient  to  increase  the  temperatures  one  or  two  degrees.  The  record  by  officers  of  the  customs  for 
several  years  is  slightly  above  the  military  record — the  summer  mean  of  those  by  W.  A.  Whitehead, 
esc[.,  for  six  years  previous  to  1836  being  82°. 3, 

West  of  Cedar  Keys  the  line  of  80°  touches  only  at  particularly  exposed  points,  but  the  evidences 
are  clear  that  it  is  continued  in  the  direction  of  Vera  Cruz.  On  the  north  it  comes  in  at  the  foot  of 
the  principal  plateau  of  western  Texas,  and  embracing  some  portion  of  the  dry  plains  near  the  Red 
river,  it  returns  nearly  to  the  recognized  cane  districts  of  Louisiana.

Within  this  is  a  district  oi' 82°  lueaD  temperature,  emWacing  a  large  share  of  Texas,  much  of 
Louisiana,  and  a  small  portion  of  the  plains  from  Mobile  to  Savannah.  Only  tlie  southern  and  tropical 
portion  of  the  peninsula  of  Florida  attains  this  temperature,  and  it  does  not  appear  at  the  interior 
posts  of  the  neck  of  the  pemneula  between  Fort  Marion  and  Cedar  Keys.  The  difference  between  this 
temperature  and  that  of  80°  does  not  appear  to  be  significant  of  anything  beyond  a  surface  facilitating 
local  accumulation  of  heat,  except  in  the  vicinity  of  New  Orleans  and  in  South  Florida,  where  tropical 
features  are  more  fully  developed  in  summer  than  elsewhere. 

In  southwestern  Texas  the  extreme  measure  of  85°  appears,  which  belongs  to  the  exceptional 
climates  of  the  western  interior,  and  in  this  case  is  an  accumiilation  from  local  radiation  in  a  somewhat 
confined  and  sandy  valley.  But  for  the  constant  winds  of  the  Eio  G-rande  valley,  this  accumulation 
would  be  even  more  extreme.  When  these  winds  ehangefrom  their  almost  constant  point  of  southeast 
to  true  south,  they  bring  a  heated  atmosphere  like  the  desert  winds  of  the  eastern  continent,  and  the 
conditions  of  exposure  and  locality  are  desert-like  rather  tlian  tropical  in  this  lower  valley. 

In  explanation  ofthe  peculiarities  appearing  in  the  illustration  of  the  great  areas  beyond  the  plains 
and  to  the  Pacific,  we  may  begin  with  the  supposed  extension  of  the  isothermal  line  of  85°  from  the 
lower  valley  of  the  Eio  G-rande.  Though  the  illustration  of  the  continent  generally  does  not  enter  into 
the  present  purpose,  it  is  necessary  to  consider  the  areas  next  to  our  own  territory  to  arrive  at  a 
satisfactory  explanation  of  the  fEicts  recorded  in  the  registers.  The  valleys  entering  the  Eio  Grande 
from  the  south  are  unimportant  except  that  in  Chihuahua,  and  this  only,  with  the  Bolson  de  Mapimi, 
a  dry  and  lieated  basin  3800  feet  above  the  sea,  probably  reproduces  the  high  temperatures  of  the 
lower  valley.  At  El  Paso  which  is  more  elevated  and  further  north,  the  summer  mean  is  at  82°. 
Beyond  the  mountains  on  the  Gila  and  Colorado  rivers  there  are  also  no  mean  temperatures  observed, 
and  the  positions  can  only  he  defined  approximately  by  reference  to  Fort  Yuma  and  the  Great  Salt 
Lake.  The  mean  of  85°  must  necessarily  reach  to  thirty-seven  and  a  half  degrees  north  latitude  tliere, 
and  it  reappears  in  the  valley  of  San  JoacLuin  at  about  the  same  point  as  is  shown  by  the  record  at 
Fort  Miller.  The  line  is  bifurcated  in  that  direction,  and  from  the  point  of  separation  it  extends  down 
the  coast  within  the  first  range  of  mountains  and  west  of  the  G-ulf  of  California.  There  are  no  records 
below  San  Diego,  yet  the  known  characteristics  of  the  coast  climate  render  it  certain  that  neither  this 
nor  the  isothermal  of  80°  reaches  the  Pacific  shore  at  any  point  of  the  peninsula  of  California. 

Within  this  line  of  85°,  at  Fort  Yuma,  the  maximum  mean  temperature  of  90°  for  the  summer  is 
attained.  The  exposure  here  favors  the  moat  extreme  accumulation  of  heat,  as  sands  and  arid  plains 
surround  the  post  for  great  distances,  and  the  principal  winds  bring  only  sand  storms  at  this  season. 
Little  rain  falls  in  summer,  and  the  air  is  distinguished  by  the  intense  aridity  belonging  to  districts 
between  the  oscillations  of  tropical  and  temperate  rains — the  .summer  rains  of  Mexico  approaching 
near  this  point  on  the  south  without  reaching  it,  and  the  winter  rainy  season  of  the  coast  also  near  it, 
but  never  present.     Its  position  is  not  wholly  unlike  that  of  the  northern  extremity  of  the  Bed  Sea. 

The  isothermal  of  80°  is  continued  up  the  valley  of  the  Rio  G-rande  to  Dofia  Ana,  New  Mexico, 
and  it  doubtless  belongs  to  the  desert  portion  called  the  Jornada  dd  Muerto,  below  Fort  Craig. 
Beyond  this  no  records  define  it  except  at  Salt  Lake,  where  the  summer  mean  is  but  little  below  80°. 
Eeturning  from  the  western  part  ofthe  Great  Basin,  it  is  reproduced  in  the  valleys  of  California  at 
Sacramento,  and  from  the  southern  point  of  the  San  Joaquin  valley  crosses  within  the  coast  mountains 
and  remains  east  of  these  at  least  to  the  lower  half  of  the  peninsula  of  California.  The  temperature 
of  most  parts  ofthe  Great  Basin  can  only  he  taken  approximately,  but  from  the  two  positions  of  Salt

Lake  and  I<"oit  Yuma,  and  iiom  the  journals  of  Hiirvey  parties  tlie  summer  tempevaturos  are  shown 
to  lie  at  least  as  great  as  those  assigned  in  the  position  of  these  lines. 

The  line  of  75°  returns,  as  before  remarked,  a  great  distance  from  its  most  northern  point  on  the 
plains  to  the  Llano  Eatacado,  and  then  recurves  to  Albuqaerc[ue,  to  return  again  two  and  a  half 
degrees  of  latitude  for  the  lofty  plateaux  of  the  Sierra  Madre.  It  then  surrounds  the  eastern  and 
northern  rim  of  the  Grreat  Basin,  traverses  the  California  valleys  on  a  right  line  south,  and  is  the 
highest  isothermal  appearing  west  of  the  coast  range,  near  Los  Angeloa  and  San  Luis  Hey.  It  may 
he  doubted  whether  a  number  of  points  sufficient  to  define  the  line  here  could  be  found,  as  none  but 
valleys  of  the  warmest  exposure  go  beyond  72°,  on  this  western  side  of  the  mountains. 

The  plateau  of  the  Rocky  mountains  increases  in  altitude  southward  so  much  as  to  cause  the 
isothermals  from  60°  to  70°  to  run  parallel  to  it  from  Fort  Benton,  on  the  Missouri,  to  Santa  F^, 
being  as  near  each  other  at  47°  30'  of  latitude  as  at  35°.  The  upper  valleys  of  the  Missouri  and 
Columbia  rivers  are  scarcely  two  thousand  five  hundred  feet  above  the  sea,  and  much  of  the  great 
plain  of  the  Columbia  is  elevated  less  than  one  thousand  feet.  Both  plains  are  not  only  arid  in 
their  surface,  but  nearly  destitute  of  summer  rains,  and  their  mean  temperatures  for  this  season  are 
comparatively  high,  The  isothermals  of  70°  and  65°  are  but  little  separated  at  these  points,  the  first 
going  to  the  47th,  and  the  last  nearly  to  the  49th  parallel.  From  the  plains  of  the  Columbia  they 
run  nearly  south  to  San  Diego;  the  isothermal  of  65°  following  the  Willamette  valley  from  Fort  Van- 
couver, and  that  of  70°  the  valley  of  Fall  river,  east  of  the  Cascade  range,  from  Fort  Dalles;  both 
remaining  within  tho  coast  range  of  California  as  far  south  as  Monterey,  from  which  point,  though 
they  are  then  inland  at  the  western  foot  of  this  range,  they  go  southward  near  to  Los  Angeles  and 
San  Diego. 

The  isothermals  of  60°  and  62°  run  nearly  north  and  south  on  the  Eocky  mountain  plateau  to  Fort 
Massachusetts,  and  on  the  Pacific  coast  below  the  35tli  parallel.  The  valley  of  Frazer's  river,  north 
of  Puget's  Sound,  at  least  extends  the  line  of  62°  some  distance  beyond  the  island  of  Vancouver, 
and  the  temperature  of  that  island  is  known  to  be  above  that  of  Sitka,  which  has  a  summer  mean  of 
67°  and  defines  the  position  of  the  lowest  isothermal  of  the  chart  to  that  remote  point  of  the  coast. 

On  the  Bocky  mountain  plateau  the  observed  mean  at  Fort  Massachusetts  is  61°,  and  that  at  Fort 
Defiance,  much  further  south,  67°.  The  altitude  of  the  first  is  8400  feet  nearly,  and  that  of  the 
upper  valley  of  San  Luis  cLuite  the  same.  The  general  altitude  of  the  vicinity  is  much  greater,  and 
it  may  be  assigned,  at  the  Parks,  at  near  10,000  feet.  At  the  South  Pass  the  average  of  large  areas 
would  he  about  8000  feet,  which  is  diminished,  in  an  average,  farther  north  to  the  49th  paralle!. 
It  is,  perhaps,  inaccurate  to  regard  this  as  a  plateau  north  of  the  44th  parallel,  hut  it  may  well  be 
regarded  as  such  south  of  that  line  for  all  purposes  of  thermal  illustration,  notwithstanding  the 
great  altitudes  and  irregularities  of  its  surface.  In  New  Mexico,  cultivated  districts  crown  the  prin- 
cipal ranges,  as  at  Zufii,  on  the  west,  at  6500  feet ;  Las  Vegas,  Auton-Chico,  and  other  districts  on 
the  east,  at  6000  to  6800  feet;  the  Sangre  de  Christo  and  San  Luis  valleys  at  8000  feet ;  Taos  and 
Santa  Fe  at  8000  feet ;  and  the  Parks,  which  afford  abundant  pasturage,  at  9000  to  10000.  For  this 
purpose  these  districts  must  necessarily  be  regarded  as  plateaux,  above  which  the  sharp  mountain 
ranges  are  lifted,  and  where  the  summer  temperatures,  particularly,  may  be  considered  generally,

month  of  July,  and  this  single  month  does  not  differ  so  largely  from  the  mean  of  the  three  tlieie  as 
it  would  here. 

The  highest  isothermal  for  July  which  touches  Europe  is  the  line  of  Y7°,  which  crosses  the  south- 
east coast  of  Spain,  the  islands  of  Sardinia,  Sicily,  and  Candia.  A  very  large  area  east  of  the  Plains, 
and  most  of  the  country  south  of  thirty-seven  and  a  half  degrees  of  latitude,  is  warmer  here,  therefore, 
than  any  part  of  the  continent  of  Europe.  The  isothermal  of  72'^. 5  emhraces  Spain,  southern  France, 
Italy,  part  of  Austria,  and  Turkey.  The  diiference  of  July  from  the  summer  mean  would  place  the 
corresponding  line  of  division  nearly  on  the  American  isothermal  of  70°,  and  a  glance  will  show  that  all 
the  area  east  of  the  Eocky  mountains  and  south  of  Fort  Snelling,  the  points  of  the  Great  Lakes  and  New 
York  city,  attains  to  this  temperature.  The  line  of  68°,  for  July,  runs  a  little  north  of  east  from 
SochoUe,  France,  nearly  in  a  straight  line  through  Germany  and  southern  Eussia ;  that  of  63°. 5 
skirts  the  southern  coast  of  England,  and  tuns  in  the  same  direction  from  London  through  northern 
Germany  and  central  Russia.  Central  Europe  corresponds  nearly  to  the  American  lake  district,  and 
the  wheat  climates  of  England  and  the  Baltic  to  the  northern  portion  of  Maine,  Quehec,  and  Lake 
Superior,  in  summer  temperature.  The  lines  of  59°  and  54.5°  are  more  irregular  in  Europe,  curving 
northward  from  the  west  of  England  to  the  "White  sea,  and  the  lowest  mean  touching  the  north  of 
Europe  is  45°. 5.  Through  Asia,  most  of  these  lines  run  due  eastward,  those  north  of  63°, 5  only 
diverging,  that  of  59°  quite  largely,  and  spreading  fan-like  over  the  great  areas  of  northern  Asia. 
On  the  east  coast,  however,  they  all  recurve  southward  quite  abruptly. 

The  temperate  latitudes  of  northern  Africa  and  the  south  of  Asia  present  ono  or  two  points  of 
comparison  worthy  of  notice.  The  Gulf  States  and  Lower  California  are  in  the  latitude  of  the 
northern  States  of  Africa,  Egypt,  Syria,  and  Persia,  and  the  isothermal  of  81°. 5  for  July,  which 
corresponds  very  nearly  to  that  of  80"^  for  the  summer,  very  accurately  defines  this  district  of  the 
eastern  continent,  except  at  the  western  coast  of  Africa,  The  line  of  86°  for  July  is  traced  at  25° 
north  latitude  in  Africa,  and  26°  in  Asia.  These  would  be  quite  the  same  as  the  temperatures  of 
the  lower  Eio  Grande,  and  higher  than  those  of  Florida.

DISTRIBUTION  OF  TEMPERATURE  EOR  THE  AUTUMN. 


It  has  Iteen  mentioned,  in  connection  with  the  temperature  distribution  for  the  spring,  that  both 
that  seaeon  and  the  autumn  were  scarcely  capable  of  identification,  as  distinct  periods,  in  regard  to 
temperature,  which  might  he  separated  as  such  and  compared  for  the  various  districts  as  definitely  as 
the  extreme  seasons  of  winter  and  simamer.  In  the  most  northern  districts  the  autumn  proper  is  shorter 
than  elsewhere,  and  if  defined  hy  the  period  from  the  commencement  of  the  decline  of  vegetation  to 
its  complete  extinction  it  would  he  scarcely  so  much  as  sixty  days.  All  the  area  north  of  40°  of 
latitude  and  east  of  the  Kocky  mountains  shares  these  abrupt  transitions;  and  north  of  the  forty- 
second  parallel  November  belongs  more  correctly  to  the  winter  months.  At  the  45th  parallel  the 
average  mean  temperature  of  this  month  is  about  32°,  and  its  contrast  with  the  temperature  of  Sep- 
tember is  very  great.  As  the  position  of  each  month  separately,  and  of  the  single  limiting  tempera- 
tures in  regard  to  vegetation,  is  more  important  than  that  of  the  period  of  autumn  as  a  whole,  these 
features  of  the  temperature  distribution  will  be  particularly  referred  to. 

The  chart  embraces  an  isothermal  of  32°  for  November,  which  is  the  only  month  in  which  that 
line  cuts  any  district  represented,  and  a  thermal  line  is  drawn  to  define  the  mean  position  of  single 
minimum  temperatures  of  36°  to  40°,  or  of  the  first  destructive  frosts  of  each  month,  in  addition  to 
those  representing  the  mean  temperatures  of  the  entire  period  of  three  months.  The  first  of  these 
lines,  the  mean  of  32°,  occurs  only  in  November,  and  it  cuts  off  a  less  area  as  belonging  to  the  winter 
proper  than  the  same  line  in  spring  for  the  month  of  March.  The  difference  is  greatest  in  the  lake 
district  and  on  the  Atlantic  coast,  where  the  mass  of  surrounding  waters  retains  its  heat  and  modifies 
the  temperature  through  a  long  period  of  continued  low  temperature  inland,  and  whore  also  the 
spring  presents  masses  of  ice  retarding  the  summer  advance  of  heat.  Fort  Brady  and  Fort  Suelling 
illustrate  these  opposite  results.  At  Fort  Snelling  each  of  the  months  named  is  near  31°. 5,  while 
March  at  Fort  Brady  is  6^.4  colder,  and  November  1°  warmer  than  at  the  first  post.  The  whole 
district  influenced  by  the  lakes,  and  all  the  Atlantic  coast  above  Fort  Monroe,  exhibit  the  same 
results,  the  difference  between  the  two  months  being  five  to  seven  degrees,  while  at  all  the  interior 
posts  they  are  nearly  equal,  and  south  and  west  of  St.  Louis  March  has  the  highest  temperature  by 
from  one  to  three  degrees.  It  is  a  noticeable  feature  of  the  entire  temperature  distribution  that  the 
decline  in  autumn  occurs  sooner  at  the  southwest  than  elsewhere,  and  that  the  minimum  is  often  in 
December,  the  spring  returning  as  much  earlier,  and  belonging  to  March  more  decidedly  than  to  any 
other  month. 

The  thermal  line  of  32°  for  November  also  shows  that  the  temperature  conditions  for  any  entire 
line  of  latitude  across  the  continent  are  more  nearly  equalized  at  that  time  than  in  any  other  case, 
as  in  the  lake  district  and  on  the  Atlantic  coast  this  line  bends  northward  to  4T°  or  more  of  latitude,  and 
its  position  in  its  extension  westward  is  but  little  north  of  this  parallel.     Between  the  Mississippi

and  Missouri  rivers  it  curvos  furthest  south,  showing  that  the  plains  grow  oold  more  abruptly  thiiii 
the  districts  eastward. 

In  October  no  post  gives  a  mean  temperature  approaching  this  point ;  the  lowest,  at  I"ortB 
Bipley,  Williins,  and  Massachusetts,  (New  Mexico,)  being  forty-four  and  forty-three  degrees.  The 
degree  of  heat  for  this  month  falls  off  as  much  generally  from  that  of  September  as  that  of 
November  does  from  this,  but  the  universally  high  temperature  of  September  leaves  a  measure  still 
cLuite  high.  The  following  measures  of  the  decline  of  temperature  in  the  successive  months  of 
autumn  may  be  advantageously  compared  with  the  monthly  advance  in  spring,  as  given  in  previous 
tables.  December  is  included,  in  order  to  embrace  the  entire  period  of  declining  temperature  to  the 
winter,  and  nearly  to  the  yearly  minimum  at  all  points.

These  results  show  that  the  diminution  of  heat  for  these  months  is  generally  more  uniform  than 
would  have  appeared  probable  when  the  diversity  of  the  positive  measures  is  considered.  The  falling 
off  to  September  is  always  least,  that  to  December  next,  and  those  to  October  and  November  are 
much  the  largest  cLuantitiee,  and  nearly  equal.  September  is  a  summer  month,  except  at  the  colder 
posts,  and  on  the  coast  of  California  it  is  often  the  warmest  of  the  year  ;  at  San  Francisco  one  degree 
■warmer  than  August.  The  area  between  the  Eocky  Mountains  and  the  Mississippi  grows  cold  most 
abruptly,  both  relatively  and  positively.

REPORT.  71  I 

The  temperatures  of  the  Pacific  coast  are  always  anoinalous,  and  never  more  strikingly  wo  than 
in  these  comparisons  of  points  in  the  curves  of  successivo  months.  Septemljor  is  seen  to  he  warmer 
than  August,  and  as  this  last  month  is  warmer  than  July,  the  whole  line  from  July  to  October  is 
ascending,  and  November  falls  but  little  below  the  July  mean.  The  same  results  are  found  at 
Monterey,  and  they  appear  to  belong  to  the  immediate  coast  line  for  several  degrees  of  latitude. 
The  mutual  relations  of  the  months  are  similar  to  those  of  tropical  and  equatorial  districts,  where  the 
rainy  season  reduces  the  temperature  of  the  months  of  summer,  and  the  clear  atmosphere  of  other 
months  permits  the  highest  temperatures  of  the  year. 

The  general  characteristics  of  the  curve  of  temperatm'es  through  successive  mouths  for  the  various 
districts  falls  more  appropriately  to  the  examination  of  the  annual  distribution  of  temperature,  and 
a  farther  reference  to  the  peculiarities  of  the  curve  of  declining  temperature  will  be  made  in  that 
connection. 

The  lines  marking  the  limit  of  mean  single  occurrence  of  frosts  closing  vegetation  are  most 
difficult  to  place,  and  they  can  only  be  regarded  as  approximations,  The  greatest  distance  south- 
ward to  which  cold  extremes  of  a  certain  degree  may  fall  in  the  most  severe  season,  is  a  point  almost 
equally  desirable,  yet  the  non-periodic  extremes  are  so  variable  in  themselves,  and  they  may  become 
so  great  in  certain  cases,  that  it  is  hardly  possible  to  present  a  valuable  result  in  regard  to  them.  A 
temperature  of  36°  to  40°  at  sunrise  is  usually  attended  with  frost  destructive  to  vegetation,  as  the 
position  of  the  thermometer  is  always  such  as  to  represent  less  than  the  actual  refrigeration  at  the 
open  surface.  Taking  the  point  of  40°  as  that  which  would  give  a  frost  in  disti-icts  slightly  more 
elevated  and  exposed  than  the  posts  themselves,  as  the  adjacent  country  usually  is,  and  the  com- 
parisons for  the  month  of  September  through  the  last  twelve  years  give  the  following  results. 

In  1843,  1844,  and  1845,  the  posts  of  the  south  coast  of  New  England,  New  York  harbor,  one 
or  two  in  the  valley  of  Lake  Ontario,  and  all  south  of  Pennsylvania,  gave  no  temperatures  so  low  as 
40°,  while  those  north  of  this  line  were  at  32  to  39  degrees  in  the  minimum  for  each  year. 
Westward,  St,  Louis  and  Fort  Leavenworth  were  at  this  limit  of  40°,  except  in  1844,  when  the 
temperature  of  36°  extended  as  far  southward  at  Forts  Towson  and  Jesup. 

In  1846  there  were  no  points,  in  the  observed  districts  of  the  United  StatcSj  where  tire  thermo- 
meter fell  to  40°,  the  month  being  unusually  warm. 

In  184'?  only  the  extreme  positions  northward.  Forts  Brady  and  Snelling,  experienced  tempera- 
tures below  40°. 

In  1848  the  extremes  were  very  nearly  as  in  the  first  years  named.  In  1849  the  lake  posts  of 
New  York,  Carlisle  Barracks  and  Fort  Kearney,  were  at  40°,  and  those  northward  below  and 
southward  above  this  point.  In  1850  it  was  quite  the  same  as  in  the  previous  year,  and  three  posts 
of  Oregon  come  in  to  give  the  exact  measure  of  40°,  in  addition  to  the  posts  enumerated  for  1849. 

In  1851  this  extreme  fell  but  little  farther  south— to  Forts  Scott,  Leavenworth,  and  Inde- 
pendence, and  it  did  not  appear  on  the  Pacific,  In  1852  the  stations  of  the  Pacific  and  New  Mexico 
gave  temperatures  below  40°,  as  far  south  as  Fort  Eeading,  in  California,  and  at  Forts  Defiance  and 
Santa  Fe,  in  New  Mexico.  On  the  plains,  Fort  Atkinson,  on  the  Arkansas  river,  was  the  point 
farthest  south  ;  at  St.  LouiSj  West  Point,  and  Boston,  and  along  the  line  connecting  these  points, 
there  were  none  so  low  as  40°. 

In  1853  the  low  extremes  for  September  were  quite  the  same  as  in  1852.  In  1854  they  were

otaerved  only  at  the  extreme  northern  poets  in  the  eastern  part  of  the  United  States  :  "but  in  Ne\v 
Mexico  and  California  there  was  hnt  little  change  from  the  preceding  year. 

It  will  he  seen  that  there  is  great  uniformity  in  the  position  of  a  line  representing  the  point  to 
which,  at  least,  one  extreme  of  36  to  40  degrees  occurs  in  September,  in  successive  years.  If  it 
were  possible  to  divide  the  month  it  would  give  a  more  precise  and  valuable  definition  ;  but,  as  it  is, 
a  line  separating  the  coast  of  Kew  England  south  of  Boston,  New  Yorh  below  West  Point, 
the  southern  line  of  Pennsylvania  and  through  southern  Ohio  to  St.  Louis  and  Fort  Leavenworth, 
would  divide  the  districts  of  the  eastern  United  States  in  which  frosts  might  he  expected  in  September, 
from  those  in  which  they  would  rarely  or  never  occur  in  this  month.  In  New  Mexico  all  north  of 
Santa  Fe  and  Port  Defiance,  and  in  Oregon,  at  all  points  remote  from  the  coast,  temperatures  below 
36°  might  be  expected  in  this  month  for  every  year. 

The  most  southern  points  at  which  this  measure  of  single  extremes  may  occur  are  Fort 
McHenry  and  Fort  "Washington,  Jefferson  Barracks,  and  Forts  Towson  and  Jesup,  west  of  the 
Mississippi.  The  only  instance  of  frosts  at  Port  Jesup  in  this  period  was  in  1844,  when  two  occurred 
at  the  close  of  the  month,  at  recorded  air  temperatures  of  36  and  39  degrees*.  At  the  Pacific  stations 
there  is  little  variation  in  successive  years,  and  liability  to  frosts  is  a  marked  feature  of  the  climate 
of  every  part  of  the  dry  interior. 

In  October  the  extremes  are  such  that  in  any  considerable  series  of  years  no  portion  of  the 
continent  north  of  the  latitude  of  Hew  Orleans  escapes  severe  frost.  In  1843  ii-osts  and  ice  occurred 
everywhere  except  on  the  peninsula  of  Florida,  though  they  were  lighter  on  the  Atlantic  coast  than 
westward.  In  1844  they  were  equally  general,  though  lighter  near  New  Orleans,  and  occurring  near 
the  close  of  the  month.  In  lSi5  there  were  none  south  of  Port  Towson  and  Port  Monroe,  and  light 
at  both  these  posts.  In  1846  and  the  two  succeeding  years  the  number  of  posts  was  not  so  great  as 
before,  but  for  the  first  year  the  frost  was  apparently  general  in  this  month,  and  for  1847  and  1848 
no  considerable  frost  occurred  in  the  Gulf  States.  The  temperature  of  this  month  of  1849  was  without 
any  cold  extreme  for  these  States  also,  but  in  1850  frost  and  ice  occurred  as  generally  as  in  1843.  In 
1851  many  parts  of  this  district  escaped  frost,  and  in  1852  there  was  none  below  Forts  Gribson  and 
Washington,  In  1853  frosts  and  ice  were  universal,  except  in  the  peninsula  of  Florida,  and  in  a 
small  portion  of  the  lower  valley  of  the  Bio  Grande,  but  in  1854  there  were  none  in  the  principal 
districts  bordering  the  Gulf.  Thus  in  five  years  of  a  period  of  twelve  the  formation  of  ice  occurred  so 
generally  as  to  destroy  vegetation  liable  to  be  so  cut  off,  before  the  close  of  October  in  the  States 
bordering  the  Gulf,  and  it  may  be  safe  to  assume  that  in  the  half  of  any  period  of  years  this  will 
occiu'  at  all  points  north  of  the  30th  parallel.  The  peninsula  of  Florida  below  28°  of  latitude  has  no 
instance  of  frosts  in  this  month,  and  the  same  exemption  exists  in  the  lower  valley  of  the  Rio  Grande 
for  the  few  years  observed  there. 

In  November  some  instances  occur  of  absence  of  frost  and  Ice  along  the  borders  of  the  Gulf 
through  the  entire  month  ;  1844  affords  one  of  these,  but  in  the  succeeding  year  severe  frosts  extend 
over  most  of  the  peninsula  of  Florida.  The  years  1846  and  1848  are  similar  to  1845,  and  184T  is 
still  more  extremely  cold.  There  are  no  exceptions  to  the  liability,  in  alternate  years,  at  least,  for 
any  point  except  the  south  of  Florida,  from  Fort  Brooke  to  Key  West,  and  at  the  mouths  of  the  Ilio 
Grande  and  the  Colorado  of  California. 

*Ab  tht're  are  no  military  poefs  in  the  interior  of  tlm  aouUiern  States  between  the  Mississippi  and  the  Atlantic,  a  reference  may  be 
made  to  the  observations  of  Rev.  Dr.  Allan,  of  Huntsville,  Aiabama,  where  for  nine  years,  183]  to  1839,  the  lowest  point  obsoi'ved

None  of  the  years  embraced  here  is  as  cold  as  would  be  found  in  a  period  of  ten  years  preceding, 
and  the  dates  are  generally  later  than  the  average  of  any  series  of  ten  years.  The  east  and  south  of 
Florida,  Fort  Brown,  on  the  Eio  Grande,  and  Fort  Yuma,  in  California,  quite  uniformly  arc  without 
ice  and  frost  until  December,  though  only  the  south  of  Florida,  near  Key  West,  appears  exempt  for 
all  dates. 

The  limits  just  defined  have  been  indicated  on  the  thermal  chart  by  lines  for  each  of  the  autumn 
months.  The  curvature  of  the  line  for  September,  northward  instead  of  southward,  in  ascending  the 
eastern  slope  of  the  Eocky  mountains,  is  not  less  marked  than  in  the  lines  representing  mean  tem- 
peratures, and  the  actual  dates  observed  at  Forts  Kearny  and  Laramie,  as  here  given,  may  be  referred 
to  in  proof  of  the  position  given  the  line.  West  of  Santa  F^,  in  New  Mexico,  the  line  would  proba- 
bly fall  further  south  than  it  is  now  drawn,  and  embraee  much  of  the  mountain  plateaux  south  of  Fort 
Defiance,  but  there  are  no  observations  except  at  this  post  and  Fort  Webster,  and  at  the  last  named 
there  are  no  instances  of  ice  occurring  in  September,  In  California  the  line  follows  the  Sierra 
Nevada,  and  in  Oregon  runs  directly  northward  near  the  cascade  range,  the  immediate  coast  being 
exempt  throughout.  The  line  marking  this  limit  in  October  cuts  off  a  narrow  belt  of  the  Atlantic 
coast  below  Charleston,  the  peninsula  of  Florida,  and  small  portions  of  the  coast  of  the  Gfulf  west- 
ward.    In  Texas  there  is  a  large  area  so  cut  off,  from  the  Colorado  river  to  the  Rio  Grande,  and  in

There  are  no  sufficient  data  for  comparison  with  similar  latitudes  in  Europe  in  this  important 
feature  of  temperature  distribution.  It  is  a  distinguishing  feature  of  the  climate  here,  howeyer,  that 
these  extremes  occur  in  connection  with  very  high  mean  temperatures,  and  that  they  belong  to  nearly 
every  district,  with  very  little  apparent  relation  to  mountains,  whether  near  or  distant.  In  the  inte- 
rior hasina  west  of  the  Eecby  mountains  frosts  are  more  fi'ecLuent  in  comparatively  warm  months,  yet 
scarcely  a  year  occurs  without  the  formation  of  ice  in  or  very  near  to  one  of  the  summer  months  on 
the  plains  between  the  Ohio  and  Mississippi  to  the  40th  parallel  of  latitude.  These  instances  are, 
however,  more  remarkable  as  contrasts  than  important  in  practical  results.  In  Europe  the  formation 
of  ice  in  September  is  rare,  if  it  occurs  at  all,  at  St.  Petersburg;  and  the  line  of  limit  would  probably 
extend  to  Moscow,  and  southeastward  to  Asiatic  Russia  at  SOc'  of  north  latitude.  The  difference  of 
latitude  for  western  Europe  from  that  of  the  central  United  States  in  this  respect  is  more  than  twenty 
degrees  therefore,  and  though  the  western  coast  here  shows  no  instances  of  this  phenomenon  to  the 
northern  limit  of  the  posts  of  observation,  the  distribution  of  these  extremes  is  clearly  to  a  much 
lower  latitude  here  than  on  the  eastern  continent.  At  Pekin,  China,  in  latitude  40°  north,  and  cor- 
responding in  position  with  New  York,  the  thermometer  very  rarely  falls  to  the  freezing  point  in 
October,  and  never  in  September. 

The  isothermals  proper  for  the  autumn  chart  show  less  abrupt  curvatures  generally  than  those  for 
the  spring,  and  if  the  deflections  due  to  difference  of  altitude  were  removed  most  of  the  lines  would 
nearly  follow  the  parallels  of  latitude.  The  isothermals  of  55  and  50  degrees  are  hut  slightly  sepa- 
rated in  New  England,  but  in  going  westward  they  separate  widely,  and  most  on  the  Pacific  coast, 
where  that  of  50  degrees  does  not  cut  the  coast  line  at  all,  while  that  of  55  degrees  falls  nearly  down 
to  San  Francisco.  The  lake  district  is  warm  in  autumn,  and  the  plains  at  the  west  of  it  retain  so 
large  a  measure  of  heat  that  scarcely  any  depressions  appear  in  the  lines  representing  the  me!i.n, 
though  November  would  give  an  extreme  depression  at  this  point.  To  define  the  position  of  the 
lines  for  this  extreme  month,  that  of  32°  mean  has  been  drawn  on  the  chart,  and  its  extreme  depres- 
sion west  of  the  Mississippi  to  Council  Bluffs  and  Fort  Des  Moines,  and  its  abrupt  rise  to  Fort  Brady, 
show. in  a  striking  light  the  contrast  of  these  districts  in  regard  to  the  rate  of  temperature  diminution 
as  winter  approaches. 

The  northern  part  of  the  area  illustrated  is  warmer  in  autumn  than  in  spring  by  about  five 
degrees,  the  thermal  line  of  45°  in  autumn  being  nearly  coincident  with  that  of  40°  in  spring,  but 
the  distance  separating  the  lines  is  not  the  same,  and  the  correspondence  is  restored  in  going  south- 
ward, the  isothermal  of  70°  being  in  the  same  position  in  both.  On  the  west  coast  there  is  little 
difference,  except  that  the  sea  temperatures  are  higher  in  autumn,  and  the  thermal  lines  curve  north- 
ward instead  of  southward  on  reaching  the  Pacific.  The  large  area  between  Fort  Vancouver  and  San 
Francisco,  which  is  at  52^.5  generally  in  spring,  is  again  at  the  same  measure,  and  this  degree  would 
probably  correctly  represent  much  of  the  interior  area  of  half  desert  basins  between  Humboldt  river 
and  the  Columbia. 

On  the  great  mountain  plateaux  the  lines  and  curvatures  arc  nearly  as  in  spring,  though 
warmer  at  the  northern  extremity.  The  thermal  line  of  45°  might  be  carried  across  the  Eoeky 
mountains,  at  the  41'th  parallel,  with  but  a  small  interruption,  as  these  mountains  form  but  a  narrow

range  between  the  sourcea  of  the  Missouri  and  of  the  north  hranch  of  the  Columbia.  The  obser- 
vations of  the  northern  lino  of  survey  of  the  Pacific  railroad  furnish  valuable  data  for  the  two  points 
of  Fort  Benton  and  Fort  Owen. 

At  the  Atlantic  coast  there  is  less  diversity  in  sea  temperatures  in  autumn  than  in  spring,  and 
less  contrast  with  those  of  the  land.  The  sea,  in  the  neighborhood  of  the  Gfulf  stream,  is  warmer 
than  the  land,  and  the  thermal  lines  generally  curve  slightly  northward.  At  B«:muda  the  observed 
temperature  for  a  single  year  is  Ti-^°,  which  is  warmer  than  the  continent  hy  nearly  four  degrees  of 
latitude.     A  mean  for  a  period  of  years  would  give  less  difference. 

The  Gulf  of  Mexico  is  warmer  in  autumn  than  in  spring,  though  it  varies  very  much  from 
September  to  November.  In  the  last  month  there  is  a  greater  refrigeration  of  the  western  than  of 
the  eastern  portions,  and  the  influence  of  the  cold  storms  of  that  part  of  the  Gfnlf  and  of  the  coasts  of 
Texas  and  Mexico  is  very  decided  in  depressing  the  mean  temperature.  As  the  air  temperatures 
are  deduced  from  those  of  the  water,  -however,  it  is  hardly  possible  to  define  the  isothermals 
accurately,  and  they  may  recLuire  more  decided  northward  curvatures  over  the  Gulf  than  are  here 
given  them.  South  and  east  of  Key  West,  and  in  the  vicinity  of  Cuba,  the  Gulf  stream  prevents  the 
continental  refrigeration  from  exerting  the  influence  observed  in  other  portions  of  the  Gulf,  and  the 
water  temperature  retains  its  measure  of  80°  throughout  November,* 

"With  the  west  coast  of  Eiurope  the  contrast  is  very  great  for  this  period,  and  the  isothermal  of 
50°  at  Boston  goes  to  60°  north  latitude  at  the  northward  of  Scotland,  though  it  returns,  through 
England  and  Germany,  to  47°  of  latitude  in  central  Europe.  The  warm  waters  of  the  Atlantic  exert 
so  marked  an  influence  on  the  coasts  and  islands  of  northwestern  Europe  as  almost  to  defy  comparison 
with  like  latitudes  anywhere.  Within  the  immediate  coast  a  contrast  of  less  than  five  degrees  of 
latitude  exists  in  Europe  as  compared  with  the  Atlantic  coast  here,  and  the  immediate  coast  of  the 
Pacific  here  is  CLuite  similar  to  the  European  coast  south  of  the  British  islands. 

The  oscillations  of  temperature  in  successive  years  for  the  same  months,  and  for  the  mean  of  the 
three  in  autumn,  is  less  than  that  occuring  in  the  spring  months  having  similar  temperatures.  It  is 
also  at  a  part  of  the  year  less  important,  in  every  sense,  other  than  in  regard  to  the  most  abstract 
questions  of  temperature  distribution,  and  the  illustration  of  this  range,  by  thermal  lines  for  single 
months,  has  not,  therefore,  been  given.  The  range  is  large,  however,  in  every  month,  and  that  for 
September  is  greater,  when  the  small  diminution  from  the  summer  temperatures  which  generally 
belongs  to  it  is  considered,  than  would  appear  probable,  even  in  a  climate  so  much  characterized  by 
large  measures  of  variability.  In  the  following  table  the  posts  which  were  selected  to  represent  the 
range  in  the  spring  months  are  given  with  the  maximum  range  for  the  months  of  autumn,  and  tho

The  general  features  of  this  variahility  are  the  same  as  in  spring  in  regard  to  the  preponderance 
of  the  quantitiea  below  the  mean  over  those  above  it,  and  in  the  decrease  of  range  toward  the  higher 
mean  temperatures.  November  does  not  ecLual  March  in  its  measures  of  variation,  however,  the 
maximum  variation  for  the  coldegt  post,  Port  Snelling,  being  less  by  nearly  fourteen  degrees. 

The  range  at  posts  near  the  Gulf  of  Mexico,  and  on  the  southern  Atlantic  coast,  is  surprisingly 
great  for  these  months.  At  Forts  Jesup,  Moultrie,  and  Monroe,  particnlarly,  it  seems  scarcely 
credible  that  the  same  month  should  differ  so  largely  in  temperature  in  successive  years.  But  the 
remaining  posts,  not  given  here,  confirm  these  measures,  and  there  can  be  no  doubt  of  the  reliability 
of  results  which  agree  at  stations  in  the  same  vicinity  both  in  their  absolute  and  comparative 
temperatures.  Whatever  zero  error  may  exist  in  any  instrument,  its  comparisons  for  successive

These  results  show  that  the  interior  of  Europe  has  a  large  measure  of  this  description  of 
variahility,  and  that,  if  the  corresponding  portions  of  the  two  continents  were  compared,  there  would 
be  less  difference  between  them  than  is  usually  supposed  to  exist,  if,  indeed,  any  difference  in  regard 
to  the  variability  of  mean  temperatures  remained.  It  appears  inexplicable  that  a  difference  greater 
than  the  measure  of  the  lowest  temperature  above  aero  may  occur  between  like  months  of  the 
successive  years  of  a  series  at  latitudes  ao  low,  and  at  stations  with  so  high  mean  annual  temperatures, 
as  Forta  Leavenworth  and  Snelling,  and  this  also  without  any  apparent  periodicity  or  gradation  of 
years  from  the  coldest  to  the  warmest.  These  variations  are  undoubtedly  absolutely  non-periodic, 
since  the  longest  series  of  observations  show  no  return  of  any  extreme,  by  whatever  steps  that  extreme 
was  at  first  approached,  and  the  greatest  contrasts  are  as  likely  to  occur  at  dates  very  near  each  other 
as  at  remote  points  of  the  series.

"DISTRIBUTION  OF  TEMrEEATUPvE   FOE  THE    WINTER. 


The  order  of  arrangement  of  temperature  statistics  lias  usually  been  to  place  the  results  for  the 
■winter  first,  and  in  many  systems  to  include  the  last  month  of  each  year  with  the  first  two  of  the 
next.  This  order  makes  the  winter  a  continuous  period,  and  its  measurements  of  temperature,  and 
other  conditions,  have  heretofore  been  considered  first  in  examining  results  for  the  year,  in  most  of 
the  Eui'opean  systems.  The  inconvenience  of  such  a  foiin  of  presenting  the  statistics,  has,  however, 
usually  caused  the  arrangement  of  the  results  of  observations  in  American  systems  in  seasons  derived 
from  the  single  year,  and  the  winter  is  thus  made  up  of  two  periods,  separated  by  the  remaining 
months.  In  this  arrangement  the  winter  comes  last  in  the  enumeration,  and  has  its  more  natural 
place  in  the  thermal  year,  notwithstanding  the  defect  of  its  period,  since  it  is  the  natural  close  of  the 
temperature  curve  rather  than  its  beginning.  If  the  consideration  of  time  alone  wore  not  controlling, 
it  would  be  still  more  appropriate  to  take  the  winter  period,  of  the  three  continuous  months,  as  the 
last  of  the  temperature  divisions  of  the  year. 

There  are  many  points  of  conveniencoj  at  least,  in  the  order  here  followed,  and  the  examination  of 
the  winter  features  is  facilitated  by  passing  immediately  fi-om  its  features  to  those  of  the  year.  The 
displacement  of  time  of  the  first  two  months  has,  apparently,  no  effect  on  a  general  summary,  though 
single  years  are  but  imperfectly  represented,  and  the  comparison  of  months  becomes  the  best  mode  of 
exhibiting  the  changes  of  successive  years.  The  annual  curve  of  temperature  displaces  the  thermal 
year  in  its  relation  to  the  astronomical  year  by  something  more  than  a  month,  or  from  December 
2Ist  to" January  28tii  for  the  average  of  the  United  States ;  and  two-thirds  of  the  period  designated 
as  winter  thus  belongs  to  the  descending  branch  of  the  curve.  As  the  characteristics  of  the  three 
months  are  derived  from  the  descending  temperatures  mainly,  the  more  natural  position  of  the  season 
is  at  the  last,  and  preceding  the  summary  for  the  year. 

The  area  embraced  by  these  observations  presents  an  extreme  of  low  temperature,  generally,  for 
the  winter ;  and  the  normal  continental  refrigeration,  or  that  which  would  occur  if  no  part  of  the 
continent  had  much  elevation  above  the  sea,  is,  undoubtedly,  much  exaggerated  by  the  great  altitude 
of  the  mountains  and  high  plateaux  near  the  Pacific.  The  western  half  of  the  continent  is  so  much 
affected  by  this  feature  of  configuration  that  no  low  inland  areas  experience  a  softened  climate,  like 
the  climate  of  such  areas  in  western  Europe,  and  the  c[uestion  whether  such  sea  influences  exist  here  as 
as  are  found  on  the  west  eoasis  of  the  eastern  continent,  has  been,  for  this  reason,  and  still  is,  much 
obscured.  It  is  very  clear  that  the  winter  depression  of  temperature  here  differs  more  fi'om  that  of  the 
same  latitudes  in  Europe  than  the  measure  of  summer  heat  does  from  theirs^  or,  in  a  word,  that  if  all  the 
low  temperatures  here  were  less  extreme,  the  parallelism  of  the  two  continents  would  be  nearly  restored.  * 
The  isothermals  for  the  summer  are,  on  the  whole,  in  quite  similar  positions  of  latitude  for  the  two

continents,  and  the  borders  of  the  Gulf  of  Mexico,  on  the  north,  equal  tliQ  temperatufcs  of  the  south 
shores  of  the  Mediterranean  in  the  same  latitudes.  The  line  of  68°  for  July,  in  G-ermany  and  central 
France,  is  reproduced  in  Canada,  and  on  the  plains  of  the  upper  Missouri,  on  the  same  parallel ;  and 
this  ecLuality,  at  that  part  of  the  year,  is  very  striking. 

It  is  not  intended  here  to  enter  upon  the  consideration  of  the  causes  of  this  most  conspicuous 
feature  of  winter  temperatures  on  this  continent.  There  are,  prohahly,  others  more  general  than 
that  just  mentioned,  or,  at  least,  others  than  the  vertical  configuration,  though  the  great  altitude  of 
the  mountain  districts  near  the  Pacific  must  very  much  aid  the  reduction  of  the  winter  temperature 
by  precipitating  the  moisture  of  the  sea  winds  and  surface  atmospliere,  and  by  preventing  the  circu- 
lation of  the  warm  sea  atmosphere  to  the  interior.  There  is  further  proof  that  this  cause  largely 
affects  the  temperature  distribution  in  the  high  and  uniform  temperatures  of  the  immediate  coast  of 
the  Pacific  to  the  northern  limit  of  these  observations.  The  decrease  in  the  winter  mean  is  but  ten 
degrees  for  fifteen  degrees  of  latitude  from  San  Diego  to  Astoria,  or  two-thirds  of  a  degree  of  tem- 
peratui'e  to  one  of  latitude.  Continuing  to  Sitka  there  is  a  diminution  of  six  degrees  of  temperature 
for  eleven  of  latitude,  or  nearly  the  same  proportion.  The  influence  of  the  Gulf  stream  on  the  coast 
of  Europe  is  so  great  that  the  parallel  conditions  do  not  obtain,  yet  there  is  not  a  wide  difference 
between  the  measures  of  diminution  observed  there  and  those  of  the  Pacific  coast.* 

With  this  general  feature  of  an  equable  temperatm'e  on  the  Pacific  coast,  and  a  wide  separation  of 
the  isothermal  lines,  is  next  associated  the  rapid  decrease  of  temperature  on  the  meridians  of  the  inte- 
rior and  the  compression  of  tlie  isottermals  there,  and  at  the  eastern  coast.  Of  iaotliermals  differing 
five  degrees  but  three  can  be  made  to  cut  the  Pacific  coast  from  San  Diego  to  the  49th  parallel,  while 
in  New  Mexico  six  such  lines  are  compressed  within  five  degrees  of  latitude,  and  on  a  central  meri- 
dian terminating  at  the  mouth  of  the  Eio  Grande,  thirteen  isothermals  of  five  degrees  difference 
occur,  and  on  the  Atlantic  coast  the  same  number  from  Maine  to  Florida.  The  interior  line  crosses 
twenty-three  degrees  of  latitude,  and  that  of  the  Atlantic  coast  twenty-two,  and  taking  the  differ- 
ences of  temperature  of  the  extreme  isothermals  we  find  the  diminution  to  be  at  the  rate  of  two  and 
seven-tenths  degrees  of  the  thermometer  to  one  degree  of  latitude,  a  ratio,  in  comparison  witli  that  of 
the  Pacific  coast,  of  more  than  four  to  one.  The  compression  of  lines  in  New  Mexico  is  exceptional, 
because  the  altitude  increases  very  rapidly,  yet  the  area  so  influenced  is  so  large  that  it  is  necessary 
to  represent  the  superficial  distribution  without  reducing  the  observations  to  their  ecLuivalents  at  sea 
level.  The  anomalous  distribution  whicli  would  be  introduced  by  this  course  is  elsewhere  alluded 
to,  and  it  is  as  necessary  to  adhere  to  the  mode  of  illustration  here  chosen  in  winter  as  for  other

Notwithstanding  the  groat  interior  altitudes,  tiie  general  course  of  the  winter  isothermals  very 
clearly  recognizes  the  unequal  temperatiirea  of  the  opposite  sides  of  the  continent,  which  are  ueually 
considered  to  belong  to  the  great  land  areas  in  these  latitudes.  The  point  of  natural  minimum  tem- 
peratures for  the  continent  is  broken  up  by  the  presence  of  the  great  lakes,  and  for  this  reason  the 
greatest  depression  falls  west  of  them,  though  at  several  points  further  east,  and  in  northern  Maine, 
particularly,  the  lines  fall  very  nearly  as  low.  With  an  allowance,  even  at  a  very  low  rate,  for 
decrease  of  temperature  with  the  altitudCj  the  curve  of  the  isothermals  from  the  Mississippi  westward 
would  be  cLuite  sharp  toward  the  north,  and  the  analogies  of  the  winter  distribution  on  the  eastern 
continent  would  be  found  to  hold.  But  for  the  local  influence  of  the  great  lakes  this  curvature  would 
evidently  find  its  lowest  point  farther  east,  and  the  coldest  district  would  fail,  as  in  Asia,  near 
the  eastern  border  of  the  continent. 

The  ameliorating  influence  of  the  lakes  is  too  decidedly  marked  to  escape  attention,  and  its 
favorable  effect  on  the  general  climate  cannot  be  unimportant.  The  peninsula  of  Michigan,  Ohio, 
New  York,  and  Vermont,  with  much  of  Canada,  show  decidedly  higher  temperatures  near  the  lakes, 
and  the  abrupt  curve  of  the  isothermals  from  the  Mississippi  valley  to  Lake  Michigan  proves  tliat  the 
altitude  is  not  the  cause  of  the  amelioration.  The  presence  of  these  large  bodies  of  water  in  the 
area  when  the  greatest  winter  cold  would  naturally  fall,  is  most  fortunate  for  the  cultivable  districts 
of  this  part  of  the  United  States,  and  though  they  may,  from  some  addition  to  the  humidity,  add 
something  to  the  sensible  temperature  of  the  colder  months,  they  prevent  the  extreme  low  tempera- 
tures which  would  otherwise  occur. 

The  east  side  of  the  continent  agrees  strikingly  in  temperature  with  similar  latitudes  of  the  east 
of  Asia:  Pekin  at  40°  of  latitude  has  a  winter  mean  of  30°,  or  very  nearly  that  of  New  York.  The 
general  position  of  the  isothermals  for  January  given  by  Dove  for  the  two  coasts  is  quite  similar,  and 
the  Asiatic  coast  has  also  a  warm  ocean  current  similar  to  the  Gulf  stream.  The  greater  contrasts 
of  the  two  continents  thus  belong  to  the  western  areas,  or  to  the  comparison  of  this  as  a  whole  with 
the  unusually  warm  area  of  western  Europe. 

The  position  of  the  thermal  lines  in  the  northeast,  on  leaving  the  coast  towards  the  interior, 
should  have  a  sharper  curve  southward  than  that  given  them  from  the  posts  of  northern  Maine,  as 
these,  Forts  Kent,  IFairfleld,  &c.,  are  much  less  elevated  above  the  sea  than  the  interior  of  New 
England  generally.  The  lake  valleys  are  all  low  also,  and  the  isothermal  of  25°  recurves  from 
Port  Ontario  to  the  highlands  of  southern  New  York,  and  falls  off  southward  some  distance  before 
finding  a  passage  across  the  high  interior  of  these  States.  The  line  of  32°  has  less  curvature  at  the 
mountains  it  passes^  and  its  general  course  from  the  coast  to  the  interior  is  slightly  south  of  west — at 
its  lowest  point  on  the  plains  being  near  three  degrees  south  of  its  position  near  New  York,  on  the 
Atlantic  coast. 

Below  this  line  the  isothermals  are  but  little  curved,  and  they  all  tend  southwestwardly,  though, 
with  corrections  for  altitude,  they  would  recurve  northward  beyond  the  Mississippi,  except  at  the 
Lower  Rio  Grande.  At  this  last  point  it  is  clearly  colder  in  winter  than  at  the  sea  level  in  any 
corresponding  part  of  Florida.  The  peninsula  of  Florida  has  two  thermal  lines  which  do  not 
appear  in  Texas,  those  of  65'  and  70°,  and  the  highest  temperature  of  Texas,  fi2°.5,  cuts  the  Florida 
peninsula  at  the  middle,  and  at  a  point  two  and  a  half  degrees  of  latitude  furtlier  north  than  its 
position  in  Texas. 

As  it  is,  the  central  portion  of  the  plains  at  about  the  'JTLh  meridian  is  the  line  of  minimum

temperatures,  and  of  the  most  extreme  southward  curvatures.  West  of  this  they  divide  in  hoth 
directions,  going  much  further  south  on  the  high  plains  of  Texas,  and  bending  still  more  sharply 
north  on  the  northern  part  of  the  great  plains.  The  line  of  32°  is  the  first  which  curves  north 
instead  of  south  as  the  altitudes  increase—that  of  30°  changes  position  still  more,  and  that  of  25'^ 
passes  from  a  point  south  of  Fort  Kearney  on  a  diagonal  to  the  areas  of  latitude  and  longitude  to  the 
sources  of  the  Miseoiiri  river,  or  across  eight  degrees  of  latitude.  This  is  an  unexpected  result,  which 
is  due  in  part  to  the  decrease  of  altitude  on  this  line  from  the  Arkansas  to  the  Upper  Missouri  of 
more  than  fifteen  hundred  feet  at  105°  west  longitude,  and  of  two  thousand  feet  from  Fort  Laramie. 

On  the  plateaux  of  the  Rocky  mountains,  and  in  New  Mexico,  the  curvatures  are  generally  similar 
for  all  seasons.  The  great  return  curves  are  mainly  due  to  altitude,  and  they  bring  the  winter 
climate  of  Fort  Mackinac  down  to  thirty-seven  and  a  half  degrees  of  latitude  in  New  Mexico — a  mean 
of  20'-'  heing  found  there,  at  Fort  Massachusetts,  while  the  mean  of  40°  occurs  at  Fort  Monroe  on  the 
same  parallel  of  the  Atlantic  coast.  The  line  of  32°  lies  south  of  Santa  F^,  and  west  of  the  Rio 
G-rande  the  plateaux  of  the  Sierra  Madre,  at  Fort  Defiance,  are  two  or  three  degrees  colder  still. 

From  this  last  point  the  thermal  lines  of  20°,  25°,  and  30°,  run  on  true  diagonal  lines  north- 
west, and  those  of  32°  and  35°  nearly  so,  making  only  a  single  curvature  southwestward  in  the 
mountains  of  Oregon  ;  but  neither  of  these  lines  reaches  the  coast  at  any  point  south  of  Sitka,  in 
latitude  57°.  The  line  of  40°  is  pressed  westward  by  the  mountains  so  much  as  to  run  parallel  to 
the  coast  from  the  northern  line  of  the  chart  to  California,  and  here  it  turns  to  the  Sierra  Nevada, 
which  is  followed  most  of  its  length.  The  position  of  this  line,  and  of  those  of  45°  and  50°,  is 
undetermined  between  the  posts  of  California  and  those  of  New  Mexico,  hut  they  are  connected  in 
the  view  that  the  deserts  which  they  cross  are  here  elevated  and  cold  in  winter,  and  that  the  districts 
east  of  the  Colorado  are  still  more  decidedly  cold  at  this  season,  as  they  are  known  to  he  very  greatly 
elevated  in  the  vicinity  of  the  thirty-fifth  parallel.  The  lower  valley  of  the  Colorado,  at  Fort  Yuma, 
gives  a  high  winter  temperature,  compared  with  the  districts  in  its  vicinity,  yet  it  is  much  less 
extreme  in  this  comparison  than  at  other  seasons.  On  the  coast,  as  has  before  been  noticed,  the  lines 
have  a  sharp  curve  northward,  and  they  are  widely  separated,  those  of  45°,  50°,  and  55°,  only 
appearing  on  its  whole  extent. 

At  sea,  on  the  Pacific  side,  the  absolute  temperatures  are  at  once  higher  than  those  of  the  land, 
and  higher  than  in  summer  for  two  or  three  degrees  of  longitude  next  the  coast.  The  thermal  linos 
hend  abruptly  to  conform  to  this  difference,  hut  it  is  probable  that  after  changing  position  four  or  five 
degrees  of  latitude,  they  follow  the  parallels  for  an  indefinite  distance  toward  the  central  regions  of 
the  Pacific  ocean.  The  mean  of  a  sufficient  number  of  observations  to  afford  a  near  approximation 
to  the  water  temperatures  here,  gives  the  numbers  56,  59,  57,  57,  and  58,*  for  successive  areas  of  five 
degrees  extent,  both  in  latitude  and  longitude,  from  San  Francisco  to  the  meridian  of  the  Sandwich 
Islands.  On  the  next  line  of  similar  areas  southward,  or  between  30°  and  35°  north  latitude,  the 
numbers  taken  successively  from  the  coast  are  56.5,  67,  63,  64,  and  57.  The  number  of  observations 
in  this  case  is  less  than  before,  and  the  irregularity  is  due  to  this  fact,  in  all  probability. 

In.  the  Grulf  of  Mexico  the  water  temperatures  are  much  above  those  of  either  coast.  The  mean 
of  three  sets  of  observations,  equidistant  in  the  area  from  New  Orleans  to  the  25th  parallel,  gives 
70°  for  the  body  of  water  nearest  the  coast,  73°  for  the  second,  and  76°  for  the  vicinity  of  the  25th 
parallel.     Yet  the  temperature  at  Fort  Brown,  near  the  mouth  of  the  Rio  Grande,  is  but  62°. 3,  and

Key  West,  at  thia  parallel,  and  surrounded  by  warm  waters,  has  a  winter  mean  of  but  70'^.  There 
is,  undoubtedly,  a  difference  as  great  between  the  temperature  of  the  air  of  the  Gulf  in  winter  and 
that  of  the  waters,  as  between  the  measure  at  Key  West  and  that  derired  from  the  mean  of  water 
temperatures  at  this  parallel.  The  known  preponderance  of  land  winds,  and  the  frequent  occurrence 
of  great  depressions  of  temperature  during  these  winds,  may  account  for  a  greater  difference  between 
sea  and  air  temperatures,  under  these  circumstances,  than  would  be  found  elsewhere.  Sudden  and 
extreme  changes,  reducing  the  temperature  of  the  air  many  degrees  for  two  or  three  days,  are 
characteristic  of  the  winter  climates  all  around  the  Gulf,  and  a*  the  surface  waters  continually  come 
from  warmer  climates  to  supply  the  draught  of  the  Gulf  stream,  the  water  participates  less  in  these 
depressions  than  the  air,  or  than  bodies  of  water  not  constantly  supplied  with  new  accessions. 

The  Gulf  coasts  are  not  modified  by  its  high  temperature  in  winter  so  much  as  would  seem 
inevitable  under  ordinary  circumstances,  and  the  only  apparent  reason  is  the  great  relative  refrigera- 
tion of  the  continent  generally,  and  the  consequent  prevalence  of  land  winds  instead  of  winds  toward 
the  continent.  These  winds  are  violent,  also,  in  proportion  to  the  contrast  of  temperatures,  and  as 
no  general  atmospheric  circulation  aids  to  drive  the  sea  air  inland,  as  is  the  case  in  the  west  winds  of 
the  European  coaat,  and  to  some  extent  in  the  summer  winds  of  the  Gulf,  the  natural  reversion  from 
the  land  prevails,  and  little  modification  of  the  climate  of  winter  is  due  to  the  presence  of  warm 
waters  in  the  Gulf. 

Similar  results  belong  to  most  of  the  Atlantic  coast,  and  the  thermal  lines  all  eiirve  largely  north- 
ward under  the  influence  of  the  warm  waters  of  the  Gulf  stream.  Observations  of  water  tempera- 
ture, very  near  the  coast,  give  measures  but  little  higher  than  those  observed  at  posts  on  the  land ; 
but  at  short  distances  at  sea  the  increase  of  temperature  is  very  great,  and  if  the  prevalent  winds 
were  reversed,  the  climate  would  be  greatly  softened  by  the  proximity  of  waters  of  so  high  a  tempera- 
ture. Off  the  coast  at  Fort  Monroe,  the  first  set  of  observations,  from  a  breadth  of  one  degree  of 
longitude,  gives  a  mean  for  the  water  of  46°,  the  next  61°,  and  65°,  69°,  68°,  and  67°,  successively; 
showing  a  rapid  increase,  and  a  very  high  temperature  for  the  central  bands  of  the  Gulf  stream, 
beyond  which  they  fall  off  somewhat.*  These  temperatures  nuist  greatly  modify  the  heat  of  the 
atmosphere  of  the  vicinity  at  least ;  and  they  require  the  compression  of  the  isothermals  quite  closely 
along  the  northeastern  coast  and  near  Newfoundland.  As  the  sea  has  a  temperature  of  nearly  50° 
at  the  40th  parallel,  and  within  the  principal  part  of  the  Gulf  stream — the  mean  of  sixty-five  obser- 
vations off  the  coast  between  37^°  and  40°  of  latitude  and  west  of  70°  of  longitude  being  51°,  the 
isothermal  of  50°  must  come  near  this  latitude  on  the  meridian  of  Newfoundland,  and  the  lines  from 
25°  to  50°  are,  therefore,  compressed  into  a  space  of  seven  degrees  of  latitude  in  winter  on  the 
Newfoundland  banks.  At  high  temperatures  the  measure  for  the  air  may  differ  largely  from  that  for 
the  water,  especially  where  strong  atmospheric  movements  from  land  areas  change  the  temperature 
rapidly,  but  at  temperatures  near  32°  the  difference  is  much  less,  and  over  unfrozen  seas  the  air  is 
usually  retained  at  or  near  that  temperature,  when  great  comparative  depressions  occur  on  the  land. 
In  constructing  the  isothermals  of  the  northern  boundary  for  the  winter,  the  most  thorough  com- 
parison of  accessible  data  beyond  the  limits  of  the  United  States  has  been  made  to  ascertain  whether 
the  positions  given  by  the  military  posts  there  would  be  essentially  modified  in  any  case.     At  this

season  tlie  changes  for  like  distances  of  latitude  are  greater  than  at  anj  otherj  and  the  minimum  of 
continental  temperatures  is  well  defined,  falling  to  zero  of  Fahrenheit  at  the  95th  meridian.     The 
ohservations  in  British  America  are  made  up  of  several  Series  at  St.  Johns,  Newfoundland;  at  Hali- 
fax and  Fredericl!:ton,K,B.,Q«ehec,  and  Montreal,  republished  by  Dov^ ;  the  valuable  aeriesat  Toronto, 
and  a  large  collection,  by  Eichardaon,  of  temperature  observationB  near  Lake  Superior  and  in  every 
part  of  British  America.*    In  this  last  collection  there  are  posts  on  the  Ottawa  river;  at  Michipi- 
eoten  and  Fort  William,  on  Lake  Superior ;  Rupert  House,  Oxford  House,  Cumberland  House,  and 
others  in  the  immediate  vicinity  of  the  positions  given  to  the  thermallineaof  the  charts,  or  in  the  direc- 
tion of  their  extension  beyond  the  United  States  boundary.     These  references  have  greatly  aided  in 
affirming  the  positiona  outlined  by  the  observations  at  the  military  posts,  and  there  is  no  inatance  of 
any  considerable  discrepancy,  such  as  might  be  likely  to  occur,  even  with  entire  accuracy  of  all  the 
records,  from  the  differences  of  date  and  the  short  periods  of  observation  in  the  different  cases.     It  is 
evident  that  the  non-periodic  range  of  winter  mean  temperatures  is  less  than  that  of  other  seasons  in 
the  highest  observed  latitudes,  and  less  than  that  belonging  to  the  same  period  in  the  south  of  the 
United  States.     The  following  comparisons  illustrate  this  important  fact  in  temperature  distribution:

The  posts  of  the  western  interior  are  seen  to  be  exceptional,  and  to  have  nearly  as  great  a  range  as 
those  at  the  south,  yet  it  is  clear  that  low  temperature  alone,  beyond  a  certain  limit,  has  the  effect  to 
diminish  the  range  of  non-periodic  oscillations,  and  to  render  the  climate  more  equable.  If  this  out- 
lined result  shall  be  found  to  be  sustained,  it  would  point  to  the  conclusion  that  the  great  non-periodic 
variations  of  temperature  are  confined  to  the  temperate  latitudes  mainly,  or  are  only  intruded  into 
the  arctic  regions  in  the  summer  and  in  connection  with  a  certain  degree  of  heat,  and  certain  condi- 
tions characteristic  of  temperate  climates.f  The  most  striking  range  is  shown  at  Fort  Moultrie,  and, 
in  the  absence  of  supporting  observations,  its  accuracy  might  be  doubted,  but  the  extreme  dates,  which 

»Prof.  H.  W.  Dove,  in  Transactions  of  Berlin  Acaaemy,  1848,  and  in  Rep.  of  British  AsBooiation,  1817  and  1848  ■,  Col.  Sabine,

Rupert's  Land,  by  Sir  John  Richardson,  1859;  Canadian  Joarnal  of  Ag.  and  Science,  etc. 

t  The  Arctic  temperatures  hitherto  published  are  scarcely  decisive  of  this  point,  yet  the  uniformity  of  winter  temperatures  in  very 
cold  climatea  is  constantly  noticed.  Richardson  remarks  tliat  "in  the  high  latitudea  the  mean  heat  of  the  three  winter  months  doea  not 
vary  greatly  in  different  years,"  and  that  "the  intense  winter  colds  are  due,  in  a  great  measure,  to  active  and  undisturbed  radiation." 
He  also  infeia  a  small  range  of  summer  temperatures  in  high  latitudes ;  but  there  are  frequent  references,  both  in  Richardson's  work  and 
in  others  of  a  like  character,  to  seasons  "a  month  later"  oi-  a  inontli  earlier  tlian  iieitiI,  and  to  great  differences  in  tlio  amount  of  ice

are  1828  for  the  high  temperatures,  and  ]831  for  the  cold  extreme,  are  also  the  dates  compared  at  ^t. 
Augustine,  Florida,  with  nearly  the  same  range.  At  Augusta  arsenal,  Georgia,  the  same  dates  give 
a  range  of  14°. 3,  and  at  Fort  Johnston,  N.  C,  a  range  of  16°. 7,  or  precisely  the  same  as  that 
observed  at  Fort  Moultrie. 

On  the  Pacific  coast  the  periods  are  insufficient  to  show  what  the  range  for  the  winter  may  be, 
but  the  greatest  recorded  in  periods  of  six  years  is  four  degrees.  It  is  undoubtedly  less  than  that 
for  any  other  districts,  as,  at  Key  West,  years  next  succeeding  eaeh  other  frequently  give  a  greater 
range,  and  the  greatest  in  fourteen  years  is  8.2  degrees,  The  stations  in  New  Mexico  are  also 
incomplete  in  their  periods ;  but  the  range  appears  to  be  very  nearly  the  same  as  at  the  same  temper- 
atures in  the  eastern  United  States. 

The  range  for  single  months  of  the  winter  has  less  practical  importance  than  that  for  the  seasons 
previously  noticed,  except,  perhaps,  at  the  extreme  south,  where  a  semi-tropical  cultivation  exists. 
This  range  is  everywhere  very  great,  and  the  minimum  in  any  winter  very  irregular  in  its  position 
in  the  period  of  three  months.  There  is,  also,  the  most  absolutely  non-periodic  character  belonging 
to  all  these  changes,  both  as  regards  the  same  year  and  in  a  series  of  years.  As  an  instance,  the 
mean  for  January  at  New  York  is  fifteen  times  below  30°  in  a  period  of  thirty-three  years,  yet  there 
is  no  similarity  in  the  relations  of  any  single  date  or  succession  of  dates,  and  no  approach  to 
symmetry  of  the  curves  of  a  line  traced  through  the  successive  means.  In  a  line  so  traced  for 
January  there  are  five  instances  of  large  departures,  with  one  or  two  years  intervening  between  the 
extremes ;  but  there  are  also  many  single  departures  or  differences,  nearly  ec[ual  to  those,  made  up 
of  two  or  three  years,  and  there  is  no  apparent  conformity  of  any  portion  of  the  line  with  a  striking 
feature  of  any  other  portion.  In  February  there  are  three  or  four  high  and  low  points,  but  they  are 
uneijual  in  degree  and  in  distance.  In  December  the  same  great  and  unequal  variations  occur,  with  a 
preponderance  of  large  changes  in  single  years,  as  in  February ;  and  the  only  noticeable  feature 
of  uniformity  is  that  the  opposite  extreme  for  any  month  may  be  expected  in  the  first  year,  or 
within  two  or  three  years,  following  a  very  warm  or  very  cold  month. 

The  period  of  a  month  is  generally  taken  as  the  average  duration  of  the  greater  number  of  non- 
periodic  variations,  and  these  comparisons  confirm  the  correctness  of  this  definition  of  the  period  of 
a  large  class  at  least,  as  the  number  of  contrasts  is  equal  to  the  number  of  coincidences  in  comparing 
the  three  months.  Taking  the  coincidences,  or  the  curve  for  the  whole  winter,  into  consideration, 
we  find  the  same  irregularity  of  position,  and  the  same  preponderance  of  large  changes  in  a  single 
year.  If  there  is  a  periodicity  in  either  period,  no  trace  of  it  is  apparent  in  the  curves  for  this  period 
of  thirty-three  years. 

The  discussion  of  other  series  is  perhaps  unnecessary  in  this  connection,  as  it  is  apparent  at  a 
glance  that  their  general  features  are  the  same.  The  field  opened  for  tracing  the  position  and 
degree  of  these  non-periodic  variations  is,  however,  an  unequalled  one  in  respect  to  the  area  they 
influence,  if  not  sufficient,  in  regard  to  time,  to  decide  the  question  of  periodicity  beyond  question. 
As  the  signal  monthly  extremes  belong  more  decidedly  than  otherwise  to  the  colder  months,  some 
comparison  of  the  districts  influenced  by  these  variations  may  be  made  liere. 

Taking  the  cold  extremes  first,  and  commencing  with  the  single  months  of  winter,  we  find  five 
instances,  in  thirty-five  years,  of  a  mean  below  6°  for  January  at  Fort  Snelling,  The  lowest,  in 
1820,  appears  to  have  been  general,  but  it  cannot  be  traced,  as  there  were  then  few  perfect  records; 
the  next  below  6°  was  in  1834,  and  belonged  only  to  January ;  in   the  lake   district  and  at  the  east

there  was  "but  little  change,  and  the  depression  was  not  thrown  forward  into  the  next  month;  hut  all 
the  western  interior  had  a  temperature  eight  to  twelve  degrees  helow  the  average,  even  as  far  south 
as  Fort  Jeaup.     At  New  Orleans  the  fall  was  less,  and  Key  West  was  ahout  five  degrees  ahove  the 
mean.     This  refrigeration  was  evidently  confined  to  the  interior,  and  had  no  progressive  movement, 
as  the  following  month  was  of  a  higher  temperature  than  usual  everywhere.     The  next  of  this  class 
was  in  1847,  and  the  cold  characterized  the  whole  winter,  with  much  the  lowest  point  in  January. 
Going  east,  as  before,  from  Fort  Snelling,  the  cold  of  the  whole  period  disappears  in  New  York  and 
the  northeast;  hut  the  upper  lakes  show  a  considerahle  depression,  which  extends,  as  hefore,  only 
toward  the  south  and  west,  and  disappears  hefore  reaching  Florida.     At  these  posts,  again,  the  heat 
is  much  ahove  the  mean,  and  this  is  the  case  as  far  north  as  Fort  Monroe.     The  next  instance  is  in 
1849,  when  January  is  the  coldest  point  of  a  cold  winter  at  Port  Snelling,  as  in  the  previous  cases; 
it  is  similarly  cold  at  all  the  northern  poets  to  the  Atlantic,  and  as  far  south  as  New  York ;  hut 
there  is  little  change  at  Detroit  and  in  the  interior  southward;  the  south  Atlantic  posts  are  at  the 
average  temperature,  and  those  of  Florida  warmer  than  usual  in  January,  though  two  or  three 
degrees  colder  in  February.     At  New  Orleans  this  last  feature  was  still  more  decided,  but  the 
western  interior  gave,  as  in  the  previous  cases,  the  same  low  temperature  that  was  felt  at  Fort 
Snelling.      In  1854  the  lowest  point   since  1820   was  observed  at  this  post  in  January,  and  the 
relations  of  this  may  be  widely  traced  at  the  west ;  but  at  the  ea^t  it  was  not  felt  at  all,  and  in 
Florida  a  reverse  condition  prevailed  to  some  extent,— at  Key  "West  5°  of  excess  above  the  mean 
temperature.     All  the  western  interior  participated  in  the  depression,  as  before,  with  the  whole  of 
the  continent  westward  from  Fort  Snelling,  including  California  and  some  parts  of  New  Mexico. 
The  difference  at  Fort  Laramie  was  8°,5  ;  at  the  posts  of  Oregon,  8  to  10  degrees  ;  and  in  California 
3  to  5  degrees,  except  at  the  two  posts  of  the  south,  San  Diego  and  Fort  Yuma.     At  stations  in  the 
Rocky  mountains  at  47"  north  latitude  the  same  depression  occurred,* 

Of  extreme  low  temperatures  less  marked  at  Fort  Snelling,  the  first  in  January  is  in  1831,  and  this 
was  universal  in  the  south  and  west,  but  it  disappeared  at  Fort  Mackinac  and  in  the  lake  district,  and 
it  was  felt  hut  very  slightly  north  of  Philadelphia.  At  Key  West  it  also  disappeared,  but  at  other 
posts  in  Florida  there  was  a  fall  of  some  degrees. 

In  1838  and  1844,  great  depressions  of  temperature  occurred  at  Fort  Snelling  in  January,  and  in 
1823,  1829,  1832, 1835,  1843,  and  1853  nearly  equal  extremes  of  cold  in  February.  In  December, 
the  years  1822, 1831, 1848,  and  1849  were  so  distinguished.  Thecoldof  1838  was  in  both  January  and 
February,  hut  at  every  other  point  it  occurred  only  in  the  latter  month,  and  it  was  then  quite 
universal,  and  as  severe  at  the  east  and  south  as  at  Fort  Snelling.  In  1844  the  cold  of  January  was 
but  four  degrees  helow  the  mean  at  Fort  Snelling,  and  about  tlie  same  in  the  lake  district,  but  north 
and  east  of  New  York  it  was  eight  to  ten  degrees  below.  South  of  St.  Louis  the  month  was  warmer 
than  usual  by  four  to  six  degrees. 

Of  the  February  extremes  that  of  1823  appears  to  have  been  universal,  at  it  occurs  at  Fort 
Jesup,  in  Florida  and  South  Carolina,  and  at  Fort  Sullivan  in  nearly  the  same  degree.  That  of 
1829  was  almost  equally  general,  disappearing  in  Maine  and  the  south  of  Florida,  and  having  its 
largest  measure  at  St.  Louis  ;  that  of  1832  was  confined  to  the  northwest,  the  lake  district,  and 
Maine,  while  the  south  was  five  to  eight  degrees  above  the  mean  ;  that  of  1835  waa  very  severe  at 
the  southwest  and  south,  causing  disastrous  frosts  in  Florida  and  the  semi-tropical  districts,  but

moderate  and  unimportant  over  the  entire  north.  In  1843  the  greatest  non-periodic  variation  occnrred, 
emtraoing  March,  and  giving  a  decreasing  temperature  from  the  mean  of  January  through  "both 
the  following  months,  over  all  the  south  and  west,  It  was  less  extreme  in  Florida  than  the  cold 
of  1835,  but  much  greater  everywhere  else.  In  the  northeast  the  minimum  was  in  February;  and 
the  depression  not  so  great  as  elsewhere.  The  February  minimum  of  1853  was  coniined  to  the 
extreme  northwest,  appearing  only  at  the  poets  nearest  Fort  Snelling. 

Of  the  December  extremes  that  of  1831  was  very  general  and  severe,  embracing  Fioiida,  and 
having  the  largest  measure  of  depression  at  almost  every  point  that  appears  for  this  month  in  any  year. 
That  of  1848  appears  only  at  the  northwest,  and  at  the  southwest  above  Fort  Jesup,  while  at  the 
east  and  south  the  temperature  is  some  degrees  above  the  mean.  That  of  1849  is  confined  to  the 
northwest  alone,  and  no  compensating  extreme  appears  at  any  point. 

This  examination  of  the  non-periodic  depressions  of  temperature  has  been  made  upon  the  striking 
winter  extremes  because  they  are  more  readily  tretced,  and  their  law  should  be  more  easily  dedncible 
from  such  marked  cases.  The  points  which  may  be  noticed  are,  that  from  this  central  continental 
area  defined  by  Fort  Snelling  there  appears  no  progressive  movement  of  these  extremes,  that  is,  they 
are  not  first  observed  here  and  subsequently  transferred  to  another  month  at  the  extreme  point  of  any 
line  of  distance.  That  of  1843  continued  much  longest  at  the  west  and  southwest,  moving  in  that 
direction  if  any  movement  could  be  supposed,  but  there  are  no  other  evidences  of  movement.  Those 
of  January  generally  influenced  the  western  districts  uniformly,  were  interrupted  or  modified  in  the 
lake  district,  and  had  some  evidence  of  the  existence  of  compensating  temperatures  at  the  southeast 
and  northeast.  But  in  February  there  were  no  important  indications  of  this  sort,  and  in  December 
but  one  appearance  of  compensating  temperature.  In  1854  the  refrigeration  belonged  to  nearly  the 
whole  continent,  and  there  was  certainly  no  evidence  of  progressive  movement. 

In  examining  other  series  for  periods  of  about  thirty  years,  the  number  of  depressions  of  tempera- 
ture amounting  to  five  degrees  on  the  monthly  mean  is  generally  five  for  each  month,  or  nearly  as 
many  as  at  Fort  Snelling.  The  entire  area  east  of  the  Eocky  mountains  appears  liable  to  an  equal 
number  of  these  variations,  and  to  measures  for  each  more  nearly  equal  than  would  be  found  if  these 
variations  were  the  consequence  of  continental  influences  alone,  and  though  they  have  been  examined 
from  the  point  which  may  be  regarded  as  the  maximum  district  of  refrigeration,  the  oscillations  are 
certainly  no  greater  at  Fort  Snelling  than  at  posts  much  less  distant  from  the  coasts.  The  most 
important  inferences  are  that  the  origin  of  these  non-periodic  oscillations  is  exterior  to  the  continent, 
and  that  they  are  central  to  the  belt  of  temperate  climates— that  they  have  no  progressive  movement, 
and  that  they  are  modified  by  local  influences  from  land  or  water  surfaces,  but  not  essentially  controlled 
by  them  in  any  case.

MEAN  ANNUAL  DISTRIBUTION  OF  HEAT. 


The  distribution  of  heat  exhibited  by  the  mean  temperaturea  for  the  year  leas  cleaily  illuatrates 
any  positive  condition  than  that  for  either  of  the  aeaaona,  and,  aa  the  curve  for  the  various  parts  of 
the  year  is  greater  here  than  in  most  observed  countries,  it  is  proportionally  further  from  the  desired 
poaitive  value  in  auch  comparisons.  The  mean  for  the  year  is  passed  in  the  annual  march  of 
temperature,  during  the  months  of  April  and  October,  and  in  the  central  diatiicts,  at  the  80th  to  the 
90th  meridiana,  these  two  months  are  very  nearly  correct  representatives  of  the  mean  temperature  for 
the  year.  At  the  east  of  this  line  April  is  always  below  the  mean  and  October  above  it,  and  this 
difference  is  greatoat  at  the  farthest  points  north  and  east,  amounting  to  about  two  and  a  half  degrees 
of  deficiency  for  April,  and  to  four  degrees  of  excess  for  October.  The  pointa  representing  the  annual 
mean  would  be  at  the  close  of  these,  or  at  the  first  of  the  following  months.  The  same  distribution 
exiats  in  the  lake  district,  but  west  of  it  April  at  once  becomes  warmer  than  the  year,  and  for  the 
interior  north  of  St.  Louis  both  months  are  two  degrees  or  more  above  the  annual  mean  ;  showing 
that  the  number  of  days  above  the  mean  is  greater  than  of  those  below  it,  and  that  the  coM  is  more 
extreme  than  the  heat,  or  a  greater  departure  from  the  natural  symmetry.  In  the  southwest  October 
is  more  or  leas  below  the  mean,  and  April  two  or  three  degrees  above  it,  but  this  feature  belongs  to 
the  eastern  part  of  the  plains,  and  not  to  Texas.  At  most  of  the  posts  in  Texas  both  montha  are 
above  the  mean.  On  the  western  side  of  the  plains,  at  Fort  Laramie,  April  is  again  below  and 
October  above ;  in  New  Mexico  they  appear  nearly  eCLual,  though  the  periods  are  imperfect.  In 
California  October  is  often  the  warmest  of  the  year,  and  there  is  no  regular  curve,  but  in  Oregon 
the  annual  curve  appears  to  be  thrown  forward  as  in  the  Atlantic  States. 

An  analysis  of  the  curve  for  each  of  these  districts  by  the  aid  of  daily  means  of  temperature 
would  have  great  value,  and  without  it  we  can  only  roughly  say  that  the  point  where  the  temporatui'e 
march  for  the  year  cuts  the  mean  may  change  from  the  1st  of  April  to  the  1st  of  May,  and  from, 
perhaps,  the  10th  of  October  to  the  10th  of  November.  The  number  of  days  above  the  mean  is 
generally  greater  than  the  number  below,  and  for  the  interior  east  of  the  Eocky  mountains  greater 
by  nearly  half  a  month.  In  a  very  valuable  review  of  a  series  of  temperature  observations  at 
Toronto,  Canada,  for  twelve  years.  Colonel  Sabine*  gives  the  mean  or  nominal  temperatures  for  that 
latitude,  43°  40',  aa  taken  from  Dove's  "Verbreitung  der  Warme,"  and  aleo  the  thermic  anomaly,  or 
differencea  of  the  Toronto  measures  from  these  theoretical  normal  CLuantitiea.  As  this  series  is  a 
type  of  all  the  aeries  of  these  posts  north  of  35°  of  latitude,  it  may  be  identified  in  its  departurea 
from  normal  measures  with  much  the  larger  number  of  these  atations.  In  the  remarks  relating  to 
distribution  of  temperature  for  the  apring  the  differences  of  succeasive  months  at  that  season  were

An  approximate  reduction  of  the  observations  at  Fort  Winnehago  to  sea  level  is  made  at  the 
rate  of  a  degree  for  about  three  hundred  and  eighty  feet  of  altitude.  It  is  very  evident,  from  these 
differences,  that  the  contrast  of  American  and  European  temperatures  in  the  same  latitudes  belongs 
mainly  to  the  low  temperature  side,  and  that  the  winter  gives  the  extreme  of  difference,  or  anomaly. 
It  is  apparent,  too,  that  there  are  defects  in  this  assumed  normal  scale,  and  that  it  does  not  curve 
sufficiently,  particularly  for  the  lower  months,  to  represent  the  natural  or  average  land  climates 
derived  from  all  parts  of  the  hemisphere,  in  this  latitude.  There  is  great  reason  to  suppose  that  a 
series  of  stations  on  any  parallel  here  would  give  the  measures  which  might  be  taken  as  the  normsil 
degree  of  heat,  quite  as  correctly  as  a  series  crossing  the  entire  eastern  continent,  or  as  numbers 
derived  from  theoretical  considerations  in  regard  to  the  amount  of  heat  distributed  by  the  eun's  rays 
on  any  parallel  of  latitude.  For  the  purpose  of  a  rough  examination  of  this  point,  the  following 
stations  are  taken  nearly  on  this  line,  and  about  equally  distant:  Fort  Preble,  Fort  "Winnebago, 
Fort  Laramie,  and  Fort  Vancouver,  The  last  two  series  are  for  defective  periods,  or  those  insufficient 
to  remove  the  large  measures  of  non-periodic  variation  which  are  found  in  every  case,  and  in  each  of 
these  December  is  evidently  too  cold,  and  January  too  warm.  The  temperatures  at  Fort  Winnebago 
are  reduced  to  sea  level  by  adding  one  degree  for  three  hundred  and  eighty  feet  of  altitude  nearly, 
or  two  degrees  for  the  altitude  of  the  post.  At  Fort  Laramie  the  rule  which  obtains  in  Europe  for 
decrease  of  temperature  with  the  altitude,  evidently  will  not  apply  at  all,  as  the  summer  temperature, 
particularly,  would  by  this  rule  of  reduction  exceed  those  observed  anywhere  at  sea  level  near  this 
latitude.  An  assumed  decrease  of  one  degree  for  about  five  hundred  and  seventy  feet  gives  a  result 
apparently  satisfactory,  or  about  eight  degrees  added  to  the  observed  mean  temperature  for  every 
month.  The  four  series  combined,  after  these  corrections,  give  a  curve  which  differs  from  that  of 
Dove  by  nearly  like  measures  of  excess  in  summer  and  diminution  in  winter,  and  in  this  rude  way 
confirms  the  view  that  the  natural  curve  of  temperatures  for  the  continent  is  greater  than  that  given 
by  Dov6,  and  that  the  temperature  anomaly  of  the  extreme  months  ia  less  here  than  the  amount 
which  has  hitherto  been  assigned  to  it.  It  will  be  seen  that  in  respect  to  this  curve  the  absolute 
correction  for  altitude  at  Fort  Laramie  is  unimportant,  and  that  if  now  in  excess,  it  only  adds  to  tho 
yearly  mean  of  temperature.

These  differences  are  mainly  in  ihe  curve  of  monthly  means,  and  they  scarcely  affect  the  annual 
mean  for  the  latitude  as  determined  hy  Dove's  empirical  formulas.  The  normal  mean,  which  is  so 
far  departed  from  at  Toronto,  ia  restored  hy  the  introduction  of  the  other  series,  but  the  curve  of 
monthly  'differences  remains  in  marked  contrast  with  those  assumed  for  Europe.  If  the  entire 
eastern  continent  were  embraced,  or  the  highly  heated  and  dry  areas  similar  to  those  of  the  western 
interior  here,  it  is  evident  that  a  higher  summer  curvature  and  a  lower  winter  depression  would  be 
found  for  the  eastern  continent  as  a  whole. 

There  are  too  many  imperfect  data  in  this  comparison  to  give  it  more  than  negative  value,  or  to 
show  that,  with  existing  records,  a  positive  standard  cannot  he  constructed.  These  series  also  show 
that  the  range  of  non-periodic  variations  is  everywhere  such  that  an  extended  period  of  time  is  more 
important  than  any  other  consideration,  in  determining  any  one  of  these  principal  points  in  regard  to 
the  curve  of  temperature,  and  its  distrihntion  for  the  year. 

The  isothermals  of  the  chart  for  the  year  are  generally  widely  separated  for  differences  of  five 
degrees.  East  of  the  95th  meridian  they  are  parallel  with  the  lines  of  latitude  for  districts  of 
moderate  altitude,  except  at  Lake  Superior  and  on  a  portion  of  the  Atlantic  coast  from  I"ort  Monroe 
to  Florida,  and  at  these  points  they  curve  northward.  West  from  the  95th  meridian  those  above  the 
40th  parallel  of  latitude  would  go  northwest,  with  proper  corrections  for  altitude,  and  those  below, 
though  curving  north  in  the  interior,  would  return  in  a  singular  manner  along  the  coast  of 
California  to  points  three  or  four  degrees  of  latitude  south  of  their  position  in  the  Mississippi  valley. 
Between  the  isothermals  of  50°  and  55*^  the  same  large  area  occurs  on  the  Pacific  coast  north  of 
Monterey  and  San  Francisco,  which  is  seen  on  the  thermal  charts  for  spring  and  autumn,  and  the 
isothermal  of  50°  for  the  year  would  go  north  of  the  50th  pai-allel  before  striking  the  coast. 

The  mountainous  interior  is  uncLuestionably  more  highly  heated  than  any  known  district  of  the 
same  altitude,  as  may  be  seen  by  applying  rules  of  reduction  to  the  means  for  the  year.  With  any 
number  whatever  (as  570  feet)  the  mean  at  Fort  Laramie  becomes  as  great  as  that  at  Fort  Monroe, 
or  58°  ;  but  Forts  Massachusetts  and  Defiance,  in  New  Mexico,  fall  below  the  temperatures  of  their 
latitude  at  the  east,  and  only  Santa  Fe,  with  others  in  the  Eio  Grande  valley,  exceed  those 
temperatures.  At  Salt  Lake,  Cantonment  Loring,  and  other  posts  of  observation  northward,  the 
highest  rule  of  reduction  would  be  recLuired,  as  at  Fort  Laramie  ;  and  it  appears  that  two  or  three 
stations  of  the  greatest  altitude  in  New  Mexico  alone  permit  the  use  of  a  rate  of  reduction  at  all 
approximating  that  found  to  apply  in  Europe.  At  Fort  Massachusetts  a  rate  of  one  degree  for  475 
feet  would  be  required  to  conform  its  temperature  to  that  of  Fort  Monroe  in  the  same  latitude  on  the 
Atlantic  coast ;  and  if  the  western  part  of  the  continent  were  supposed  to  be  warmer  by  five  degrees 
of  latitude,  the  reduction  would  be  one  degree  for  330  feet.     But  at  Fort  Laramie  and  Great  Salt.

730  REPORT. 

Lake  the  recorded  temperatures  are  already  higher  than  those  of  either  coast  at  the  same  parallels, 
though  their  altitudes  are  4500  and  4350  feet.  In  the  southern  part  of  New  Mexico,  at  an  altitude 
of  4000  to  4500  feet,  the  temperatures  are  also  nearly  as  high  as  at  either  coast,  heing,  in  fact,  ahove 
those  of  the  Pacific,  and  below  those  of  the  Atlantic,  hy  equal  differences. 

It  ia  ohvious  that  the  surface  peculiarities  of  the  elevated  districts  of  that  portion  of  the 
continent  are  favorahle  to  a  great  accumulation  of  heat,  bnt  this  arid  character  may  be  itself  due  to 
the  altitude,  and  the  heat  might  not  be  greater  than  elsewhere  in  the  absence  of  the  mountains. 
"With  the  existing  aridity  the  effect  of  altitude  may  only  be  neutralized,  one  modification  of 
temperature  compensating  the  other ;  but  there  is  no  reason  to  suppose  that  these  districts 
would  have  less  heat  than  similar  positions  in  Europe,  if  the  country  were  generally  as  near  the  sea 
level ;  and  in  that  case  all  the  isothermals  would  curve  northward  from  the  Mississippi  valley.  The 
rate  of  correction  for  altitudes  would  then  be  something  more  than  twice  the  number  of  feet  for  a 
degree  in  every  case  here,  than  in  the  rule  applicable  in  central  Europe. 

These  results  show  that  the  constitution  of  the  surface  and  the  general  configuration,  together, 
perhaps,  with  the  degree  of  humidity  as  a  possibly  separate  element,  control  the  temperature 
in  a  very  great  degree,  and  more,  within  certain  limits,  than  latitude  and  altitude.  Humboldt 
observes  the  increased  mean  annual  temperatui-e  of  the  plateaux  of  the  Cordilleras  in  tropical  regions, 
and  gives  the  measure  of  excess  over  the  temperature  of  mountain  declivities  at  the  same  heights  as 
2°. 7  to  i°.\.  We  have  no  vertical  altitudes  to  compare  for  the  interior  posts  here,  but  if  the  recog- 
nized measures  of  the  Atlantic  coast  of  this  continent  and  of  Europe  are  assumed,  the  excess  of 
temperature  on  the  Boclry  mountain  plateaux  is  several  times  greater  than  these  numbers.  There  is 
scarcely  any  district  where  the  mean  temperature  at  considerable  altitudes  might  be  taken  for  that  at 
sea  level  for  a  higher  latitude. 

The  distribution  of  heat  for  latitude  is  directly  associated  by  Humboldt  with  that  for  altitude, 
though  there  would  seem  to  he  little  parallelism  here  with  these  relations  as  they  exist  in  Europe. 
On  the  Pacific  coast  here  the  decrease  of  temperature  with  the  latitude  is  very  slow,  the  isothermals 
of  65°  and  50°  for  the  year  being  separated  hy  at  least  twenty  degrees  of  latitude;  or,  using 
positive  points  on  the  coast,  San  Diego  and  Sitka,  separated  by  twenty-four  and  one-third  degrees 
of  latitude,  differ  16°. 6  in  mean  annual  temperature — a  decrease  of  0°.68  for  one  degree  of  latitude. 
In  central  Europe  this  decrease  is  0°.9  for  one  degree  of  latitude,*  but  there  are  no  similar  points 
here  at  or  near  sea  level  to  compare,  except  in  the  Mississippi  valley,  where  the  decrease  is 
thirty  degrees  of  temperature  for  eighteen  of  latitude — nearly  1°.T  for  each.  This  is  also  the  rate 
between  the  extreme  posts  of  the  Atlantic  coast,  including  the  whole  peninsula  of  Florida,  as 
previously  assigned  for  the  distance  from  Boston  to  Charleston  by  Humboldt,  who  gives  in  addition, 
the  rate  of  lo.6  for  the  coast  from  Boston  to  Labrador. 

The  interesting  features  of  the  relation  of  these  two  conditions  of  distribution  in  the  interior 
cannot  be  followed  further  here,  but  they  deserve  attention  more  minutely.  There  is  very  little 
decrease  of  temperature  for  certain  measures  of  latitude  and  altitude  over  a  large  district. 

The  influence  of  the  cold  coa^t  of  California  appears  very  decidedly  in  the  position  of  the  isother- 
mals for  the  year.  The  cause  of  this  phenomenon  has  been  sufficiently  explained  in  connection  with 
the  summer  illustration,  and  it  may  be  disposed  of  very  briefly  here.     It  is  a  great  and  remarkable

anomaly  even  when  exhibited  in  the  mean  temperatures  for  the  year,  and  the  cause  of  it,  with  the 
like  cold  current  and  mass  of  water  off  the  coast  of  South  America  in  the  Pacific,  shows  the  existence 
of  most  extensive  oceanic  circulations  and  interchanges  there.  But  no  mass  of  cold  waters  could 
produce  so  great  an  effect  upon  land  climates  as  are  found  here,  if  there  was  not  a  great  interior 
rarefaction,  originating  and  intensifying  the  winds  from  this  cold  sea  inland,  and  the  two  causes 
produce  a  cumulative  result  which  has  no  parallel. 

The  range  of  mean  temperatures  for  the  year  in  any  series  is  very  large  for  every  part  of  the 
United  States,  and  it  proves  that  the  period  of  a  year  is  far  from  being  the  whole  time  embraced  by 
the  greater  non-periodic  variations,  and  that,  whatever  the  period  of  these  extremes,  any  single 
year  may  be  distinguished  by  several  oscillations  having  the  same  direction,  either  above  or  below 
the  annual  mean.  Either  as  months  or  seasons  we  may  readily  point  out  conspicuous  instances. 
In  the  series  of  thirty-three  years  at  Fort  Columbus,  New  York,  the  year  1836  is  distinguished  as 
that  of  lowest  temperature,  being  four  degrees  below  the  general  mean.  Every  month  of  the  year 
was  below  the  mean,  though  in  unecLual  measures,  and  those  most  extreme  were  February  and 
October.  The  previous  year  and  that  next  following,  1835  and  1837,  were  the  next  lowest,  each 
being  more  than  two  degrees  below.  Two  months  only,  and  the  same  months,  October  and  Novem- 
ber, of  each  of  these  years,  were  at  or  above  their  average  temperatures  respectively ;  and  with  these 
exceptions  the  whole  period,  including  the  last  five  months  of  1834,  or  nearly  three  and  a  half  years, 
was  decidedly  below  the  mean  temperature.  A  similar  general  result  occured  at  !Fort  Snelling  for 
the  mean  of  these  years  and  for  their  warmer  months,  but  the  colder  months  were  variable  and  the 
difference  for  the  year  less ;  and  this  was  the  case  in  every  part  of  the  United  States,  with  some 
irregularities,  and  generally  with  greater  measures  of  variation. 

There  is  no  other  conspicuous  group  of  cold  years  in  this  period,  though  1823  and  1824  and  1843 
and  1844  are  together  below  the  mean  at  some  posts — the  last  two  quite  generally.  Two  or  three 
years  near  1812  are,  however,  known  historically  as  cold  years,  and  a  reference  to  records  of  that 
date  shows  them  to  have  been  more  extreme  than  those  of  1836,  &c.* 

The  variations  of  a  non-periodic  character  toward  higher  temperatures  have  not  been  noticed  for 
any  part  of  the  year,  and  they  may  be  briefly  referred  to  here,  though  excess  of  heat  is  a  phenome- 
non naturally  preceding  a  great  diminution  of  heat,  and  if  any  appearances  of  progressive  movement 
or  periodicity  were  apparent  they  should  be  associated  with  extremes  of  high  temperature. 

In  the  yearly  means  there  are  two  groups  distinguished  by  high  temperatures,  one  from  1824  to 
1830,  inclusive,  of  which  1825,  1828,  and  1830  were  the  most  marked  years;  and  another  period 
from  1844  to  1848,  each  of  the  years  of  which  was  nearly  uniformly  above  the  mean.  The  first  of  these 
periods  is  the  most  general,  and  it  is  quite  conspicuous  at  the  south  and  west ;  but  the  second  is 
irregularly  distributed,  and  the  measures  of  excess  belong  to  shorter  periods.  The  most  conspicuous 
single  years  at  Fort  Snelling  are  1830  and  1846,  and  these  are  also  everywhere  so  distinguished, 
1825  and  1828  being  next.  On  the  Pacific  coast,  1853  is  marked  as  the  warmest  year  of  the  period 
there  observed;  and  the  summer  of  that  year  was  everywhere  much  above  the  average  temperature. 

The  higher  temperatures  are  quite  irregularly  distributed  in  respect  to  the  seasons  and  months, 
and  an  analysis  of  any  series  would  give  results  analogous  to  those  indicated  in  the  examination  of

the  low  temperature  extremes.  G-enerally,  the  coincidences  of  single  months  with  the  seasons  and 
the  yearly  mean  are  more  numerous  tiian  the  contrasts  for  any  year,  as  of  eight  cases  in  the  period  of 
33  years  at  Fort  Oolumhus,  New  York,  of  a  mean  temperature  for  the  spring  months  two  degrees  or 
more  above  the  general  mean,  six  were  coincident  with  like  differences  for  the  summer,  autumn,  and 
year ;  and  the  same  proportions  occur  in  comparing  summer  and  autumn  with  other  seasons  and  the 
year.  There  might  be  supposed  to  he  two  classes  of  these  non-periodic  changes,  one  less  frequent 
and  affecting  longer  periods,  and  another  causing  changes  above  or  below  the  general  line  of  these 
long  periods,  and  belonging  to  periods  of  a  month  or  less. 

There  are  few  instances  of  very  high  temperatures  for  any  month  in  a  cold  year,  or  of  very  low 
monthly  means  in  a  warm  year;  and,  though  the  succession  of  years  is  full  of  extreme  contrasts  in 
respect  to  months,  there  is  some  decided  conformity  in  the  relations  of  the  successive  months  of  any 
year  of  which  the  mean  is  particularly  cold  or  warm.  This  is  in  part  necessary  consequence,  it  is 
true ;  hut  the  point  of  importance  is,  that  if  any  part  of  the  year  is  marked  hy  an  extreme  oscilla- 
tion it  does  not  find  a  compensating  extreme  in  that  year. 

It  may  be  of  interest  to  trace  some  of  the  greater  instances  of  high  temperature  occurring  at  Fort 
Snelling  in  their  relations  to  other  portions  of  the  continent,  as  was  done  with  the  winter  extremes 
of  cold.  The  spring  and  summer  of  1825  are  together  largely  above  the  average  temperature  at  this 
post,  the  excess  belonging  to  every  month  from  February  to  September.  This  high  temperature  was 
almost  universally  of  the  same  degree  and  duration,  the  exceptions  applying  to  one  or  two  months 
only;  as,  at  some  posts  in  the  south,  April  was  at  or  below  the  mean,  and  in  Maine  the  two  extreiue 
months  were  but  very  little  warmer  than  usual.  At  the  west,  and  in  the  central  districts,  the  excess 
was  greatest^  and  at  Fort  Moultrie  least.  The  very  high  temperature  of  the  winter  of  1827-8,  which 
was  from  seven  to  nine  degrees  above  the  mean  for  each  month  at  the  south,  gradually  disappeared 
at  the  northeast  and  west,  and  was  not  felt  at  all  at  several  posts  nearest  Fort  Snelling.  In  1830 
the  whole  year  was  warm,  and  July  eight  degrees  in  excess  at  Fort  Snelling ;  the  same  month  is 
noticed  as  " unprecedentedly  hot"  at  Fort  Winnebago,  where  it  was  near  thirteen  degrees  in  excess. 
This  peculiar  heat  of  July  occurred  at  all  the  central  districts  to  the  Atlantic  coast;  but  it  was  not 
felt  at  the  northeastern  posts,  nor  in  so  great  a  degree  at  the  south  as  in  the  interior.  In  1834  July 
had  a  high  temperature  at  Fort  Snelling ;  in  the  district  above  St.  Louis  the  conditions  were  the 
same,  but  at  Fort  Gibson  the  greatest  excess  was  in  August,  the  mean  of  which  was  88°. 22,  giving 
the  highest  temperatures  anywhere  recorded  at  that  latitude  in  the  interior.  The  heat  of  July  was 
again  extended  through  the  central  districts  to  the  Atlantic  at  Baltimore  and  Fort  Monroe,  but  was 
not  observed  east  of  New  York.  In  1839  April  was  eleven  degrees  above  the  mean  at  Fort  Snelling, 
and  as  it  comes  between  two  months  which  were  below,  its  progress  may  be  traced  with  advantage. 
This  extreme  was  the  same  in  all  the  northwest — less  marked  south  and  southwest— and  not  appearing 
at  all  in  Florida  and  Georgia;  but  it  was  partially  felt  through  the  central  States  eastward.  It  had 
no  change  of  position  towards  any  other  month  at  any  post. 

There  are  other  cases  which  may  be  traced  with  the  same  general  result,  and  other  points  from 
which  the  examination  may  be  made  with  a  similar  absence  of  any  evidence  of  progressive  movement 
or  periodicity.  In  June,  1853,  a  very  high  temperature  occurred  in  the  central  States  east  of  St. 
Louis,  which  was  not  felt  at  all  at  Port  Snelling.  The  occurrence  of  extreme  high  temperatures 
appears  to  be  of  the  same  absolutely  non-periodic  character,  and  to  have  the  same  liability  to  fall  in 
nearly  equal  measures  on  any  district,  as  was  apparent  in  the  low  temperature  extremes.

734  REfOET. 

The  imperfect  periods  for  the  Pacific  stations  and  those  of  the  western  interior,  render  them  rude 
approximations  to  positive  results.  The  large  annual  range  is  one  of  the  most  striking  features  of 
the  table ;  and  particularly  for  tlie  Atlantic  coast  stations,  as  at  Fort  Columbus  and  Fort  Monroe, 
The  range  is  large,  also,  along  the  Gulf  coast  and  in  Florida,  and  it  appears  to  dimininish  equally 
toward  each  of  the  extreme  stations  of  the  Atlantic  coast — Fort  Sullivan,  Maine,  and  Key  West,  In 
the  vicinity  of  Fort  Snelling  the  range  attains  ita  maximum,  reaching  thirteen  degrees  on  the  plains 
of  Wisconsin ;  and  the  district  stretching  from  this  point  through  the  central  part  of  the  United  States 
to  Fort  Monroe,  has  probably  near  ten  degrees  of  range  of  mean  annual  temperature  in  any  period  of 
the  extent  of  twenty-five  years. 

The  range  disclosed  in  the  Toronto  series  of  twelve  years  is  but  four  degrees  between  the  years 
1843  and  1846  ;  but  1836  is  elsewhere  often  lower  than  the  first,  and  1830  higher  than  the  last  of 
these,  and  the  range  of  a  period  of  twenty  or  thirty  years  is  probably  six  degrees  there  instead  of 
four.  This  is  still  lower  than  in  the  central  United  States  southward,  and  lower  than  on  the  plains ; 
and  it  is  evident  that  tho  range  is  less,  as  a  rule,  in  the  lake  district,  and  that  it  diminishes  rapidly 
northeastward. 

All  the  features  of  the  range  of  mean  temperatures  show  larger  measures  than  would  he 
anticipated,  and  tho  concurrence  of  stations  in  similar  positions  is  required  to  confirm  them.  This 
concurrence  is  generally  shown  by  the  table,  and  those  that  appeared  most  likely  to  be  in  error  were 
particularly  examined  and  verified. 

At  the  stations  of  New  Mexico  and  the  Pacific  coast  there  is  some  reason  to  fear  the  existence  of 
constant  errors  of  observation,  arising  from  the  position  of  the  thermometer,  and  from  the  frequent 
interruptions  of  the  record  ;  but  the  differences  of  the  extremes  of  any  series  are  evidently  much  leas 
there  than  at  the  east  of  tlie  Eocky  mountains.  Fort  Laramie  gives  a  much  larger  range  for  the 
same  dates  than  Port  Steilacoom, 

By  the  aid  of  the  serial  tables,  recently  published  in  Europe,  the  comparison  of  the  distin- 
guishing temperature  periods  of  this  series,  with  those  of  Europe  generally,  may  now  be  very  thoroughly 
made,  and  one  or  two  citations  may  be  introduced  here.  In  the  range  of  annual  mean  temperatures  two 
series  of  observations  of  temperature  in  the  interior  of  Europe,  at  Oracow  and  Riga,*  bring  the  record 
down  from  1195  to  1852,  and  in  both  these  the  warm  years,  from  1824  to  1828,  inclusive^  are  distinctly 
marked  as  those  of  much  the  highest  temperature.  The  year  1829  is  there  the  coldest  of  a  series  of 
thirty-five  years  preceding  that  date,  as  observed  at  Eiga ;  and  183T  and  1838  are  the  coldest  of  the 
series  of  twenty-seven  years  at  Cracow,  beginning  in  1826.  The  years  1830  to  1836  are  also  there 
all  above  the  mean  temperature,  while  on  this  continent  1830  alone  was  so  marked,  the  remainder, 
except  1834  in  SOTie  districts,  were  much  below  the  annual  mean.  The  low  temperature  of  February 
and  March,  1843,  which  rendered  the  moan  of  that  year  below  the  average  in  America,  was  unknown 
in  central  Europe.

DISTEIBUTION    OF   RAIN, 


WATEU  PALLING  IN  EAIN  AND   SNOW. 


The  mode  of  presenting  the  principal  facts  of  this  distribution  is  similar  to  that  employed  in  the 
representation  of  the  distribution  of  heat,  the  districts  being  defined  in  a  general  manner  by  the  mean 
of  the  results  at  stations  in  similar  positions  of  altitude  and  exposure.  The  q^uantity  of  rain  is  less 
easily  defined  in  this  manner,  and  the  illustration  less  .exact,  than  in  the  temperature  charts  in  any 
case,  and  for  many  climates  it  could  not  be  employed  with  sufficient  precision  to  answer  any  require- 
ment of  positive  science.  In  western  Europe  slight  differences  of  altitude  very  largely  affect  the 
cLuantity  of  water  falling  in  rain,  and  for  the  British  islands  and  the  northern  coasts  of  that  conti- 
nent, as  well  as  for  the  mountainous  districts  in  the  south  and  bordering  the  Mediterranean,  there 
could  scarcely  be  any  accurate  general  illustration.  A  portion  of  the  Pacific  coast  and  western  inte- 
rior here  shares  in  these  contrasts  and  this  irregularity  without  doubt,  and  for  these  districts  any 
general  illustration  is  only  approximate  ;  but  for  much  the  larger  area  of  the  United  States,  and  for 
all  portions  east  of  the  Rocky  mountains,  the  distinguishing  feature  of  the  distribution  of  atmospheric 
precipitation  in  rain  is  its  symmetry  and  uniformity  in  amount  over  large  areas.  The  quantity  has 
rarely  or  never  any  positive  relation  to  the  configuration  of  the  surface  which  would  identify  it  with 
the  distribution  of  western  Europe  and  the  north  Pacific  coast;  and,  in  contrast  with  these,  it  has  a 
diminished  quantity  at  the  greater  altitudes  generally,  and  the  greatest  amounts  in  the  districts  near 
the  sea  level.  It  also  difi'ers  from  those  districts,  and  from  large  land  areas  generally,  in  having  a 
greater  amount  in  the  interior  than  on  the  coasts  for  the  same  latitudes,  at  least  as  far  north  as  the 
42d  pai'allel  of  latitude.  These  two  leading  features  of  the  distribution  of  rain  in  the  United  States 
are  of  great  importance  in  any  attempt  at  graphic  illustration,  and  in  their  absence  it  would  scarcely 
be  possible  to  make  any  such  illustration  clear.  They  are  of  even  greater  importance  in  the  discus- 
sion of  a  mass  of  results  derived  from  positions  widely  distributed,  and  from  observations  embracing 
a  succession  of  years,  as  they  then  have  a  symmetrical  and  associate  character  which  permits  the 
elimination  of  errors  of  every  sort  by  combining  results,  and  by  treating  them  as  a  whole.  The 
correspondence  which  belongs  to  like  quantities  must  appear  in  some  intelligible  form  in  comparing 
results  at  any  two  stations,  and  this  conforinity,  if  found  to  exist,  proves  at  once  the  reliability  of  the 
observations,  and  the  existence  of  a  general  symmetry. 

It  will  require  but  a  brief  examination  of  the  records  and  results  of  observations  to  show  that  the 

graphic  illustration  undertaken  in  the  charts  is  a  true  expression  of  general  symmetry,  and  that  if  it 

is  based  on  accurate  records,  embracing  a  sufficient  period  of  time  to  remove  the  errors  of  non-periodic 

variation,  it  represents  a  physical  fact  as  permanent  as  the  lakes  and  rivers  of  a  continent  themselves,

736  REPORT. 

since  if  any  slow  progression  of  changes  exists  affecting  the  amount  of  water  falling  in  rain  and  snow, 
an  equal  effect  must  lae  produced  on  rivers  and  Ijodies  of  water  dependent  on  rains  for  their  per- 
manence, 

The  principal  defect  of  these  results  is  in  regard  to  the  period  of  time  they  embrace.  The  non- 
periodic  variations  of  quantity  are  very  great,  and  a  series  of  many  years  is  required  to  give  a  true 
mean,  even  for  the  year,  and  much  more  for  the  months  and  seasons.  For  most  of  the  area  the  range, 
even  for  a  period  of  three  months,  may  descend  to  an  entire  absence  of  rain,  and  for  single  months 
this  entire  absence  is  quite  frequent.  For  the  year,  the  range  h  from  the  present  means  to  less  than 
half  that  quantity,  and  with  such  large  departures  a  short  period  must  necessarily  fail  to  give  more 
than  an  approximate  result.  The  larger  quantities  of  the  eastern  United  States,  and  the  vicinity  of  the 
Gfulf  particularly,  are  more  affected  by  imperfect  periods  than  other  districts  east  of  the  E.ocky  moun- 
tains, and  at  the  west  a  range  of  perhaps  one-fourth  of  the  quantities  assigned  to  the  several  districts, 
should  be  considered  as  a  possible  change  of  any  result  by  the  use  of  a  series  of  years  of  observation 
numbering  twenty  or  more.  This  possible  range,  however,  does  not  materially  affect  the  relation  of 
those  districts  to  the  eastern  United  States  generally ;  and  as  the  periods  are  nearly  equal  in  the  new 
districts,  it  may  not  sensibly  affect  the  mutual  relations  there.  In  a  district  having  an  average  of  three 
inch^  of  water  falling  for  any  period  of  three  months,  the  variation  will  be  proportioned  to  that  quan- 
tity, and  very  far  less  than  in  a  district  of  the  Mississippi  valley  having  fifteen  inches  for  a  like  period. 
The  district  embraced  by  the  observations  is,  as  said  in  relation  to  the  distribution  of  heat,  a 
complete  and  symmetrical  area,  occupying  nearly  all  the  temperate  zone  of  the  continent,  and 
illustrating  most  of  the  important  facts  of  rain  distribution  over  such  an  area.  It  is  far  more 
valuable,  even  in  regard  to  what  it  outlines,  if  the  results  are  not  of  the  rank  of  positive 
determinations,  for  this  reason,  than  if  the  measures  and  illustration  were  for  limited  areas  and 
isolated  districts.  The  comparison  of  districts  possessing  such  diverse  features  of  configuration 
cannot  fail  to  throw  light  on  the  remoter  questions  in  regai-d  to  the  sources  of  the  supply  of 
moisture  to  the  continents  generally,  as  well  as  to  the  sources  of  supply  in  this  particular  case. 

The  quantities  given  in  the  illustration  represent  the  mean  of  the  areas  in  which  they  are  placed, 
and  not,  as  in  the  isothermals,  the  measure  at  the  limiting  line.  If  the  mean  of  the  numbers 
marking  two  adjacent  areas  were  placed  on  the  line  which  separates  them,  the  definition  would  be 
the  same  as  in  the  temperature  illustration.  The  quantities  in  both  cases  pass  into  each  other  by 
gradual  transition,  and  the  abrupt  distinctions  of  shading  and  of  boundary  lines  are  employed  only 
for  convenience  and  clearness  of  illustration.  In  Johnston's  Hyetographie  or  Kain  Map  of  Europe, 
these  limiting  lines — designated  Isohyetoses  for  the  lines  of  equal  annual  amount,  and  Isotherombroses 
for  lines  marking  the  per  centage  of  the  quantities  for  summer  on  those  for  the  year — are  marked 
with  their  respective  quantities,  though  their  application  to  the  areas  enclosed  by  these  lines  is 
always  understood.*

REPORT.  737 

There  ia,  no  doubt,  some  general  deficiency  in  the  measurements  of  the  water  falling  in  anow 
at  the  military  posts,  and  the  prohabilities  are  that  the  results  for  the  winter  months  fall  somewhat 
below  the  actual  precipitation  of  these  months  in  every  form.  In  some  cases  the  entry  has  been 
made  of  the  depth  of  snow  in  inches  without  converting  it  into  water,  and  in  these  cases  one-tenth 
of  the  recorded  depth  of  snow  has  been  taken  as  its  ecLuivalent  in  water.  This  rule  is  sufficiently 
near  to  accuracy  for  any  general  purpose,  though  for  the  southern  latitudes  it  would  give  too  small, 
and  for  extreme  northern  districts  too  great  a  quantity  of  water.  The  error  of  these  measurements 
is,  however,  believed  to  be  less,  on  the  whole,  than  the  error  of  records  by  amateur  observers, 
especially  in  regard  to  imperfect  measurement  of  small  quantities  in  winter.  The  great  mass  of 
records  of  this  latter  class  are  obviously  deficient  in  this  respect,  and  with  many,  and  perhaps 
most  of  such  observers,  it  is  the  habit  to  measure  the  snows  and  to  interpret  this  measurement  in 
water  by  the  best  rule  at  their  command,  while  the  military  records  are  made  under  precise  regu- 
lations well  adapted  to  secure  correct  results.  In  the  annual  summary  it  is  believed  that  the  small 
winter  deficiency  is  compensated  for  by  a  natural  full  measurement  of  actual  rains,  and  by  the 
fractions  being  usually  thrown  in  favor  of  full  tenths  and  hundredths  in  the  entries. 

Direct  error  in  the  reading  of  the  scales  of  the  gauge  rarely  passes  for  a  period  of  two  or  three 
months  without  detection,  and  all  known  excesses  or  deficiencies,  as  well  as  those  on  which  a 
reasonable  doubt  is  thrown  by  any  evidence,  have  been  so  distinguished  in  the  register.  An  error  of 
the  deduction  and  illustration  derived  from  any  modifieation  of  the  actual  record  in  this  manner  may 
thus  be  corrected  by  subsequent  examination. 

To  perfect  the  anaiogios  in  regard  to  language  the  point  has  been,  submitted  lo  Professor  Turner,  who  concurs  with  Professor 
Johnston  in  the  use  of  tho  root,  ierof  in  preference  to  a/ijlpu;,  which  is  used,  to  aome  extent,  by  Frencli  writers,  and  from  wliiclt 
wa  hase  ombrometer  (rain-g'auge,)  ombronietry,  &c.  The  shorter  word  hyelat  is  regarded  as  standing  primarily  on  the  same  footing  as 
kydosntpMc,  and  in  its  present  use  the  analogy  of  the  atmospheric  conditions  before  alluded  to,  and  the  greater  faciJity,  perhaps,  in 
introducing  a  short  form  of  the  word,  have  controlled  the  choice  oThyelal  over  hyetographU.  These  terms  are,  at  least,  suggested  for 
the  consideration  of  those  interested  in  the  nomenclature  of  this  department  of  physical  science.

DTSTRTBUTION  OF  RAIN  FOE  THE  SPRINa, 


There  18  the  same  defect  to  be  remarked  in  this  season  in  regard  to  its  identity  as  a  single  or 
distinctire  period  that  was  observed  in  the  temperature  distrihution.  For  the  interior  dietrictSj  or 
central  meridians  particularly,  it  enters  both  winter  and  eummer,  and  it  then  has  greatly  contrasted 
quantities  of  rain  for  the  extreme  months  of  March  and  May.  When  the  observations  on  the  plains 
of  the  Bocky  mountains  shall  have  been  carried  over  all  distinctive  portions,  and  continued  for  a 
BufHcient  time,  some  useful  divisions  of  the  year  into  other  periods  may  he  made  in  this  respect,  and 
a  more  precise  knowledge  of  the  peculiarities  of  the  several  months  may  be  attained.  On  the  Pacific 
coast  also,  the  division  in  rainy  and  dry  seasons  is  generally  the  most  accurate,  and  the  commencement 
of  the  rains  and  the  date  of  their  close  are  necessary  facts.  The  Eocky  mountain  districts  have 
ecLually  distributed  rains,  generally,  and  these,  with  all  east  of  the  9Tth  meridian,  may  he  said  to 
possess  a  very  nearly  uniform  distribution  of  rain  over  the  three  months  of  spring. 

The  feature  of  uniformity  just  alluded  to  is  one  of  the  most  important  in  this  connexion,  and  as 
it  affects  the  division  of  seasons,  and  serves  to  define  the  districts  where  those  three  months  are  not 
an  appropriate  expression  of  the  desired  result,  it  may  be  well  to  examine  it  here.  For  stations 
where  the  succession  of  numbers  is  nearly  the  same  for  the  months  from  January  forward,  there  is  of 
course  no  change  of  an  abrupt  character  to  be  anticipated  in  the  succession  of 'days.  The  period 
recLuiied  to  eliminate  irregularities  and  extremes  is  so  great  that  a  combination  of  the  results  at 
stations  of  similar  position  may  furnish  a  clearer  mode  of  exhibiting  the  general  facts  than  any  list 
or  number  singly.     In  the  following  table  the  several  natural  groups  are  so  arranged :

The  results  just  given  embrace  the  whole  coast  of  the  United  States  on  the  eaafc  and  define  three 
districts ;  one  north  of  Boston,  in  which  the  amount  increases  from  March  to  May ;  another  central,  at 
New  York  and  Philadelphia,  in  which  the  quantities  are  very  nearly  eq^ual ;  and  that  at  the  south 
which  ia  cLuite  irregular,  hut  with  the  greatest  quantity  in  March  on  the  whole.  The  last  has  also 
an  anomalous  deficiency  in  April  at  most  of  the  stations,  hut  it  appears  only  in  very  small  measure 
west  of  Florida,  and  it  may  be  caused  by  irregularities  belonging  to  short  periods.  Taking  the 
Atlantic  coast  as  a  whole,  the  same  amount  of  rain  may  be  anticipated  for  every  day  of  these  three 
months — such  being,  very  accurately,  the  relation  of  results  from  Boston  to  Charleston,  and  the  extreme 
districts  differing  slightly  in  opposite  directions. 

In  the  southwestern  interior  there  is  a  rapid  increase  in  amount  from  March  to  May,  and  this  is 
also  the  case  at  all  points  west  of  the  Mississippi  and  north  of  Cincinnati,  At  Cincinnati,  Louisville, 
and  Huntsville,  Alabama,  records  for  periods  of  ten  years  and  more  give  nearly  like  amounts  for  each 
month,  but  the  districts  north  and  west,  which  are  very  fully  represented  by  the  military  posts,  show

For  all  but  the  stations  here  given  the  distribution  is  essentially  tlao  same  as  on  the 
Atlantic  coast,  the  quantity  being  controlled  T)y  the  profusion  of  the  storms  or  rains,  rather 
than  by  the  absence  of  rains.  There  is  no  period  free  from  rains,  and  no  interruption  of 
the  constant  atmospheric  precipitation  of  moisture.  On  the  plains,  however,  the  deficiency  of 
rain,  in  the  first  half  of  the  spring,  is  so  great  that  it  has  some  general  analogy  to  the 
division  in  wet  and  dry  seasons;  yet  no  distinct  points  of  such  a  division  appear  in  the 
records,  and  the  great  increase  in  the  last  month  is  more  in  profusion  than  in  frequency. 
The  whole  of  tlie  eastern  United  States  may,  therefore,  be  designated  as  an  area  of  constant  preoipi- 
tation,  and  where  this  is  not  equal  throughout  in  quantity,  it  differs  in  proportions  only. 

The  increasing  profusion  in  the  districts  west  of  the  Mississippi  is  important  in  many  respects,  and 
it  gives  an  appearance  of  periodicity  to  the  floods  of  the  great  rivers  of  the  plains.  It  is,  however, 
very  much  subject  to  non-periodic  interruption  and  variation  in  quantity,  and  though  periodic  in  a 
certain  general  sense,  it  is  not  similar  to  the  distribution  in  tropical  districts  and  on  sea  coasts,  which 
is  usually  so  designated.  The  rivers  tributary  to  the  Mississippi  from  the  west  have  generally  a  flood 
in  May ;  and  the  first  decidedly  summer-like  temperatures  of  this  month  are  accompanied  by  profuse 
and  deluging  thunder-showers.  Sometimes  these  are  deferred  till  June,  as  at  Fort  Eiley,  in  1854, 
and  at  the  posts  of  the  plains  generally,  in  1850.  In  1853  the  profusion  in  May  and  April  is  quite 
conspicuous.  The  floods  from  melting  snows  do  not  very  largely  influence  the  rivers  of  the  great 
plains,  in  the  lower  portions  of  their  course  at  least,  though  they  affect  their  sources  more  or  less,  and 
those  originating  in  the  loftier  mountains  very  largely.  The  evaporation  and  diffusion  of  water  in 
these  long  and  shoal  rivers  is  very  great ;  and  even  the  Missouri  is  said  to  gain  little  or  none  in  volume 
for  many  hundred  miles  of  its  course  below  the  mouth  of  the  Yellow  Stone.  The  Platto,  Arkansas,  and 
Canadian,  are  all  of  the  class  of  shoal  rivers ;  with  their  channels  often  bare,  In  long  reaches,  for  months 
together,  at  any  season.  The  floods  of  these  rivers  do  not  occur  in  any  marked  degree  until  the  pro- 
fuse rains  of  spring  and  early  summer  set  in ;  and  the  snows  of  tlie  mountains,  at  their  sources,  disap- 
pear too  early  to  add  largely  to  their  volume  at  this  time  in  the  lower  portions,  though  Fremont 
found  the  South  Platte,  at  the  104th  meridian  and  4,000  feet  above  the  sea,  much  swollen  by  melting 
snows  at  the  first  of  July.*  The  records  at  the  posts  situated  on  and  near  these  rivers  of  the  plains, 
contain  few  notices  of  their  condition  in  regard  to  volume,  yet  there  are  some  that  may  be 
cited  for  these  months  and  for  June.  At  Fort  Leavenworth,  on  the  Missouri,  the  river  is  noted 
as  "high"  on  the  first  of  June,  1851,  and  as  "very  high"  during  each  of  the  spring  months  of 
1853.  No  other  note,  for  these  months,  is  made  there  during  the  last  six  years.  At  Fort  Kearny, 
on  the  Platte,  no  direct  notes  appear  for  this  period — it  is  apparently  always  low  in  April,  and  full 
in  May  and  June.     It  is  the  same  at  Port  Laramie,  though  the  Laramie  river  is  noted  as  high  two

or  tLree  times  in  May  and  June.  At  Fort  Eiley  there  wa^  a  great  flood  of  the  Kansas  river  from  tlie 
1st  to  15th  of  June,  1855.  At  Fort  Atkinson  the  Arkansas  river  is  noted  as  very  low  in  April  and 
May,  1851;  on  May  26th,  "Arkansas  river  nearly  dry,  a  narrow  channel  only  a  few  inches  deep;" 
on  May  30th  "the  river  helow  is  perfectly  dry  for  many  miles."  In  the  first  days  of  June,  1851, 
there  are  several  notices  of  a  rise  of  a  few  inches,  "depending,  no  doubt,  on  the  melting  snows  of 
the  mountains."     At  the  close  of  this  month  it  was  again  very  low  and  dry. 

These  imperfect  notices  are  perhaps  sufficient  confirmation  of  the  view  that  the  melting  -snows 
rarely  form  floods  in  these  rivers,  or  preserve  their  volume  uniform,  and  that  the  rains  of  spring  and 
early  summer  are  quite  irregular,  and  at  times  quite  profuse,  sending  considerahle  floods  to  the  Mis- 
sissippi from  the  drainage  of  these  plains. 

The  plains  rise  so  gradually  to  the  great  altitudes  of  the  Bocky  mountain  plateaux,  that  the 
contrasts  in  the  quantities  of  water  falling  are  not  so  great  on  the  east  of  these  lofty  mountains  as 
elsewhere,  near  these  latitudes.  The  precipitation  changes  only  by  hecoming  more  constant  and 
regular,  for  the  high  central  plateaux,  at  least,  and  it  is  not  so  much  interrupted  in  spring  and  summer 
hy  long  periods  without  rain.  But  this  high  helt  of  constant  rains  is  very  narrow,  scarcely  reaching 
to  Santa  F^  on  the  south,  and  breaking  off  at  the  Colorado  and  Salt  Lake  vallies  on  the  west.  North- 
ward it  stretches  along  the  mountains,  but  it  evidently  does  not  embrace  the  vallies  or  plains  of  either 
branch  of  the  Columbia.  There  are  but  two  or  three  posts  on  this  plateau^  Fort  Massachusetts, 
Cantonment  Loring,  and  perhaps  one  or  two  other  temporary  posts  of  northern  New  Mexico;  and  the 
experience  of  surveys  and  expeditions  must  be  relied  on  to  indicate  what  the  rain  distribution  of  these 
districts  is.  All  these  accounts  concur  in  remarking  a  regular  succession  of  rains  and  snows  through 
the  months  of  spring,  as  in  the  eastern  United  States. 

This  mountain  district  of  equally  distributed  rains  has  some  detached  extensions  toward  the 
Pacific  coast,  one  or  two  of  which  may  be  cultivable  and  valuable.  From  the  north  the  Cascade 
range,  and  its  slopes  in  Washington  Territory,  are  of  this  character,  and  perhaps  the  immediate 
coast  hills  and  the  island  of  Vancouver.  On  this  northern  coast  of  Oregon  generally,  the  rains  are 
periodical  in  degree,  rather  than  in  absolute  cessation  in  summer,  and  it  thus  has  an  intermediate 
rank,  and  may  be  said  to  be  both  periodical  and  constant  in  a  certain  sense.  The  mountainous 
portions  of  southern  Oregon  have  rains  in  summer,  or  equally  distributed  rains,  also,  but  all  the 
plains,  valleys,  and  coasts,  are  here  strictly  periodical.  The  Sierra  Nevada  of  California  has  little 
summer  rain,  and  its  elevated  districts  seem  rather  to  prolong  the  rainy  season  of  the  coasts  than  to 
break  its  general  character,  and  to  render  the  distribution  uniform,  A  portion  of  the  interior,  or 
Rocky  mountain  system,  not  before  referred  to,  ftirnishes  other  districts  of  this  constant  character — 
one  of  limited  extent  south  of  the  Great  Salt  Lake,  and  another  in  the  Zuili  district  of  the  Sierra 
Madre,  and  on  the  extension  of  these  mountains  toward  the  Gila  and  Colorado  rivers.  Here  the 
districts  of  constant  precipitation  border  on  those  which  reverse  the  general  features  of  the  area  of 
the  United  States,  in  having  the  dry  season  and  little  rain  in  winter  and  spring,  and  the  true  rainy 
season  in  summer,  as  in  many  tropical  climates.  The  Gila  river  separates  the  districts  so  distin- 
guished; and  south  of  this  river  and  its  wide  half-desert  basin,  and  west  of  the  Colorado  of  Califor- 
nia, the  precipitation  is  wholly  in  periodical  rains. 

The  general  features  of  the  periodical  rains  of  the  Pacific  districts  are  that  they  belong  to  the 
winter  half  of  the  year,  and  that  they  occupy  a  period  of  variable  length,  regularly  increasing  with 
the  latitude,  and  generally  equally  extended  before  and  afber  a  middle  point  in  January,  For  the 
most  of  this  region  there  is  also  a  partial,  and  in  some  instances  a  complete,  suspension  of  the  rains

in  January  and  February;  constituting,  in  some  degree,  a  double  rainy  season  for  the  districts  of 
California  which  have  the  least  tain.  This  feature  is  not  rendered  snfBciently  clear  by  our  present 
knowledge  of  these  climates.  At  the  coasts  of  Oregon  the  rains  set  in  earlier  and  continue  longer, 
but  they  exhibit  the  same  general  phenomena  as  in  California,  and  are  attended  by  winds  having  the 
same  direction  in  all  cases  and  at  all  periods,  As  they  embrace  at  least  one  month  of  spring  at  all 
points,  these  general  features  must  necessarily  be  alluded  to  in  this  connexion,  and  so  far  as  tliey  are 
concerned  no  reference  will  then  be  necessary  in  a  subsequent  case. 

The  rainy  season  of  California  and  the  Pacific  coast  is  usually  marked  by  profnse  as  well  as 
continuous  rains,  especially  for  the  northern  districts  and  Oregon.  On  the  coasts  and  lower  valleys 
of  the  south  there  is  no  marked  profusion,  but  the  mountains  here  have  very  profuse  rains,  and  the 
whole  course  of  the  Sierra  Nevada  is  so  distinguished.  At  Fort  Tuma  the  rains  occur  in  November 
and  December  mainly,  with  some  instances  in  February  and  March,  and  again  in  July,  August,  and 
September.  This  last  period  appears  to  be  associated  with  the  summer  rain  of  Mexico,  and  to  be  a 
casual  extension  of  these  rains  beyond  their  proper  iield  on  the  mountains  of  Sonora,  At  San  Diego 
the  rains  commence  in  November,  and  are  most  profuse  in  December ;  they  are  partially  interrupted 
in  January,  and  are  then  continued  till  May,  and  occur  early  in  June.  December,  February,  and  a 
part  of  March,  only,  give  the  average  quantities  falling  in  like  months  in  the  eastern  United  States. 
Such  is  the  case  on  the  whole  coast  south  of  San  Francisco,  and  in  the  San  Joaquin  valley  the  only 
difference  is  that  the  months  of  December  and  March  sometimes  have  very  heavy  rains,  measuring 
fifteen  inches  or  more  for  a  month.  The  same  features  belong  to  the  Sacramento  valley.  No  rain 
falls  in  the  three  months  of  summer  in  any  part  of  California,  except  in  rare  instances  in  the  extreme 
north,  and  at  Fort  Yuma,  as  before  noticed. 

At  Fort  Orford,  and  for  the  whole  of  the  Pacific  districts  of  Oregon,  the  relation  of  quantities  is 
similar  to  that  in  California,  except  that  there  is  no  partial  suspension  in  January,  and  that  the 
fall  does  not  cease  entirely  in  the  summer  months.  The  winter  rains  are  here  very  profuse,  as  well 
as  quite  continuous  for  many  days,  and  they  are  often  continuous  for  nearly  every  day  of  a  month. 
East  of  the  Cascade  range  of  mountains  the  quantities  are  much  the  same  as  in  the  great  valleys  of 
California,  all  the  measures  being  small  and  the  summer  proper  quite  destitute  of  rain.  There  is 
but  one  military  post  which  represents  this  interior  district.  Fort  Dalles,  and  at  this  there  are 
■moderate  rains  in  each  month  of  spring,  and  they  do  not  absolutely  cease  in  summer.  On  the  great 
plains  of  the  Columbia  and  its  branches  the  summer  rains  are  wholly  shut  off. 

The  rains  of  the  great  basin  of  the  interior  are  least  known,  as  positive  measurements  have  but 
just  commenced  there.  At  Great  Salt  Lake  the  spring  months  have  frequent  rains,  and  it  may  be 
that  much  of  the  northern  portion  of  the  basin  may  be  similar,  and  that  it  may  be  more  nearly 
identified  with  the  districts  of  constant  precipitation,  or  of  equally  distributed  rains,  than  with  those  ol 
periodical  rains  for  this  season.  In  summer  they  probably  cease  entirely,  and  in  the  southern  part 
of  the  basin  they  must  always  be  very  small  in  quantity. 

The  share  of  the  precipitation  of  spring  which  falls  in  snow  is  a  point  of  general  interest,  which, 
however,  it  would  be  somewhat  diificult  to  define  with  the  desirable  precision.  North  of  the 
isothermal  of  32°  for  March,  most  of  the  water  falling  in  that  month  is  in  the  form  of  snow,  though 
rains  occur  in  about  the  same  number  and  quantity  as  in  the  months  of  winter.  Nearly  half  of  the 
precipitation  for  April  is  also  in  snow  in  this  district,  or  north  of  the  43d  parallel,  and  there  are 
instances  of  snow,  sometimes  in  considerable  quantity,  in  May.  Snow  may  occur  in  March  over 
nearly  the  whole  of  the  United  States  east  of  the  Rocky  mountains,  except  Florida,  though  the

quantity  is  not  large  in  any  case  south  of  the  40th  parallel.  In  April,  there  are  instances  in  almost 
every  year  of  much  water  falling  in  snow  in  the  elevated  districts  of  the  Atlantic  States,  as  far  south 
as  the  latitude  of  Washington,  The  enowa  of  this  month  afford  as  large  a  q^iiantity  of  water, 
usually,  as  those  of  the  previous  month,  and  they  occur  in  the  great  general  storms  peculiar  to  the 
eastern  United  States  in  the  spring  months.  In  May  these  storms  occur  at  the  great  lakes,  and 
eastward  north  of  the  42d  parallel,  but  not  elsewhere,  and  even  there  they  do  not  often  afford  a 
heavy  fall  of  snow. 

On  the  plains  the  spring  snows  are  much  less  abundant  than  in  the  Atlantic  States,  the  number  of 
storms  not  only  not  being  so  great,  but  the  volume  of  water  falling  in  snow  being  much  less  in  any 
case  than  in  similar  storms  east  of  the  Mississippi.  The  earlier  months  of  spring  are  conspicuously 
dry  in  these  western  districts,  as  may  be  seen  by  the  various  forms  in  which  the  storms  and  their 
quantity  are  noted  in  the  registers,  and  though  the  last  month,  May,  is  often  marked  by  heavy  rains, 
the  season  generally  is  more  free  from  heavy  storms,  of  either  rain  or  snow  here,  than  in  other  jiarts 
of  the  eastern  United  States. 

On  the  Kocky  mountains,  and  on  the  greatly  elevated  plateaux  belonging  to  its  general  districts, 
there  is  a  large  precipitation  in  snow  during  each  of  the  spring  months,  and  at  the  greater  altitudes 
these  storms  are  continued  quite  through  the  summer.  There  are  many  summits  on  which  there  is 
perpetual  snow  in  the  neighborhood  of  the  Parks,  and  in  the  mountain  systems  south  of  the  South 
Pass,  and  on  all  these  the  summer  storms,  which  break  as  showers  of  short  duration  on  the  plains 
and  valleys,  fall  as  equally  profuse  snows.  The  abrupt  and  detached  mountains  of  the  great  basin 
receive  a  large  fall  of  snow  in  these  months  also,  and  the  changes  of  temperature  are  so  sudden 
at  these  altitudes  that  the  storm  may  take  the  form  of  snow  on  mountains  but  little  elevated,  and 
where,  as  is  usual  in  May  in  the  Great  Basin,  the  temperature  of  the  valleys  is  approaching  summer 
heat,*  Yery  little  is  known  of  the  central  and  southern  portions  of  the  Ureat  Basin  in  this  respect, 
but  the  whole  of  its  great  area,  north  of  the  thirty-seventh  parallel,  is  undoubtedly  quite  uniform  in 
its  configuration,  and  in  this  feature  of  the  spring  climate. 

The  mountains  of  Oregon  and  California  are  similar  in  the  quantity  of  snow  they  receive,  or  in 
its  continuance  as  the  leading  form  of  precipitation  in  these  months.  In  California  and  the  south  of 
Oregon  there  is  some  appearance  of  a  duplication  of  the  rainy  season  in  the  greater  profusion  of  rains 
and  snows  in  March  than  in  January,  and  on  all  the  mountains  which  so  far  arrest  the  sea  winds  as 
to  render  the  plains  east  of  them  arid,  the  fall  of  both  rain  and  snow  is  very  great  in  this  season. 

The  number  of  days  on  which  snow  is  noted  at  the  various  posts,  for  these  months,  may  be 
readily  taken  from  the  Register,  and  from  their  examination  it  appears  that  the  average  number  on 
which  snow  falls  in  March  is  eight  to  ten  in  the  most  nortliern  districts  of  the  Atlantic  States  and  in 
the  lake  district,  with  half  this  number  for  April,  and  perhaps  two  for  May,  at  the  same  posts. 
At  the  latitude  of  Baltimore  and  St,  Louis  the  average  is  two  to  three  days  for  Marclr,  one  for  April, 
and  none  in  May,  At  Forts  Towson  and  Moultrie,  latitude  33°  to  34°,  the  instances  iu  March 
average  hut  one  in  two  years,  with  none  in  other  months.  In  northern  New  Mexico,  and  in  Oregon, 
there  are,  in  some  years,  several  days  of  snow  in  March,  as  in  1852  in  Oregon,  particularly ;  but 
the  number  is  generally  small,  and  it  is  only  at  the  most  elevated  posts  that  they  occur  in  April  and 
May.  No  reliable  average  could  be  given  for  these  districts  as  the  period  of  years  is  insufficient,  and 
the  diversity  of  positions  is  too  great  to  permit  the  combination  of  the  results  at  separate  posts.

DISTRIBUTION  OF  EAI^T  FOR  THE  SUMMER, 


The  quantity  of  rain  falling  in  Buuimer  in  the  Uniteil  States  east  of  tlie  Rocky  mountains  is 
perhaps  the  most  decisiye  distinction  of  its  general  climate  from  that  of  other  similar  areas  in 
temperate  latitudes,  though  we  can  only  compare  it  fully  with  the  western  and  interior  districts  of 
Em-ope,  and  some  points  in  Asia.  To  derive  our  analogies  from  Europe  alone,  we  must  designate 
this  as  a  half  tropical  distribution,  and  its  frequent  instances  of  great  profusion,  with  accompanying 
high  temperatures,  often  approach  the  tropical  forme  of  precipitation  very  closely,  if  they  do  not 
quite  institute  them  for  short  periods.  It  has  been  usual  in  Europe  to  designate  the  summer  rains 
in  their  per  centage  on  the  quantity  for  the  year,  and  as  the  interior  of  Russia  is  attained,  this 
proportion  amounts  to  nearly  fifty  per  cent.  It  is  generally  less,  by  regular  gradation,  on  lines 
southwestward  from  this  interior,  and  on  reaching  the  African  districts  the  summer  rains  wholly 
cease.  The  same  designation  here  would  he  less  expressive  of  this  actual  distribution,  as  it  would 
not  represent  the  actual  quantities  with  their  relations  for  the  single  period-  so  clearly.  The 
departures  here  are  from  tropical,  or  almost  tropical,  districts,  with  twenty-five  to  thirty  inches  of 
rain  for  this  season,  instead  of  being  from  districts  like  those  of  northern  Africa  with  none.  The 
quantities  of  the  interior  would  have  nearly  the  same  ratios  to  those  for  the  year,  however,  as  at  Fort 
Snelling  the  rain  of  summer  is  43  per  cent,  of  the  yeai'ly  quantity,  and  at  several  posts  of  this 
vicinity  the  proportions  are  nearly  the  same. 

For  the  whole  period  of  warm  months,  in  which  May  and  September  should  be  included,  the 
quantity  of  rain  distributed  over  the  Mississippi  valley  is  comparatively  very  great,  and  there  is  no 
great  area  so  far  in  the  interior  which  presents  a  similar  result.  The  quantities  are  absolutely  as 
well  as  relatively  large,  and  they  considerably  exceed  those  of  the  plains  of  the  Atlantic  coast  in  the 
same  latitudes.  The  line  of  fifteen  inches  for  the  three  months  goes  only  to  38°  of  latitude  on  the 
Atlantic  coast,  yet  it  rises  nearly  to  44°  in  the  Mississippi  valley,  and  occupies  a  very  wide  area 
below  the  fortieth  parallel.  The  measure  of  twelve  inches  is  equally  more  extensive  in  the  interior, 
though  neither  of  these  stretches  upon  the  plains  beyond  100°  west  longitude. 

A  contrast  still  more  striking  in  comparison  with  the  precipitation  in  Europe,  is  shown  in  the 
rapid  diminution  of  these  quantities  at  the  more  elevated  posts  generally,  particularly  in  the  AUegha- 
nies  and  in  Texas  ;  though  less  so  north  of  New  York,  where,  for  some  part  of  the  elevated  interior, 
the  quantity  of  summer  rains  is  greater  than  in  the  plains.  But  the  mountainous  districts  between 
the  Mississippi  valley  at  St,  Louis  and  Cincinnati,  and  the  Atlantic  coast  at  Fort  Monroe  and  Balti- 
more, show  the  most  marked  deficiency,  which  is  clearly  indicated  at  Pittsburg  and  Carlisle.  Each 
of  these  posts  gives  but  about  nine  and  a  half  inches  for  the  summer,  and  still  lower  proportions  exist 
southward,  as  is  shown  by  partial  records  in  the  interior  of  Virginia,  which  give  but  about  eight 
inches  for  the  summer,*

The  lake  district  also  presents  a  somewhat  anomalous  result,  in  comparison  with  other  interior 
portions  at  least,  as  it  has  less  than  the  valley  of  the  Mississippi  in  the  same  latitudes,  though  nearly 
the  same  as  the  Atlantic  coast.  The  effect  of  these  bodies  of  water  is  clearly  to  diminish  the  quantity 
of  rain  for  the  whole  period  of  the  warm  season,  though  not  so  strikingly  for  the  three  months  of 
summer  as  for  other  months.  This  deficiency  appears  very  clearly  in  the  mean  for  the  spring,  and  it 
is  conclusive  proof  that  the  local  evaporation  adds  little  or  none  to  the  quantity  of  rain  of  these 
interior  districts.  The  valley  of  the  IMississippi  and  its  extension  in  the  Ohio  valley  strikingly 
contrast  with  the  rain  fall  in  the  lake  districts,  though  this  difference  is  prohahly  due  to  greater 
profusion  rather  than  to  frequency  of  rains.  The  numher  of  days  on  which  rain  falls  is  indeed  con- 
siderably gi-eater  at  the  northern  poste  of  the  lake  district. 

The  irregular  character  of  the  rains  on  the  plains  in  summer  baa  been  alluded  to  in  connection 
with  the  distribution  for  the  spring.  They  are  less  in  number  and  more  irregular  without  having 
any  periodical  discontinuance,  and  the  whole  immense  range,  from  the  thirty-first  parallel  to  the 
northern  boundary  is  nearly  uniform  in  this  respect.  On  the  Llano  Estacado  of  Texas  there  is  the 
least  rain  probably,  and  next  is  a  belt  along  the  Canadian  river  which  has  more  than  other  districts,  as 
is  apparent  from  the  accounts  of  those  who  have  traversed  it,  and  from  the  configuration  and  cultivable 
character  which  the  districts  at  each  extremity  are  known  to  have.  The  Wichita  mountains  extend 
further  west  than  other  elevated  and  well  watered  points  on  the  plains,  of  which  there  are  some  near 
I'ort  Gibson  ;  and  the  spurs  of  the  mountains  of  New  Mexico  reach  eastward  at  Las  Vegas  and  other 
points  in  a  district  with  frequent  rains  in  summer.  The  whole  eastern  slope  of  the  Rocky  mountains 
is  still  generally  arid,  and  the  loose  soil  and  rapid  evaporation  dissipate  the  rains  and  diminish  tlie 
eifect  of  the  fall  of  any  certain  volume,  much  below  that  of  a  similar  rain  fall  on  tho  retentive  surface 
and  soil  eastward.  On  the  upper  plains  of  Texas  and  over  all  the  plains  west  of  100°  of  longitude, 
irrigation  is  generally  necessary  to  support  cultivation  which  requires  the  summer  for  its  growth,  and 
in  the  valleys  nearest  the  mountains  at  the  west  it  becomes  more  decidedly  so  than  elsewhere. 

At  the  western  border  of  these  plains  the  illustration  of  the  rain  distribution  becomes  much  less 
accurate  in  its  expression  of  the  actual  condition  than  before,  and  it  can  only  be  taken  as  an  approxi- 
mation toward  this  condition.  The  whole  area  is  so  much  broken  up  by  mountains,  that  great 
profusion  may  alternate  with  entire  absence  of  rain,  for  the  summer  at  least,  on  valleys  and  mountains 
in  the  most  immediate  proximity.  Generally,  the  valleys  of  New  Mexico  have  little  or  no  rain  in 
summer,  and  the  mountains  a  large  quantity,  and  this  is  gathered,  as  in  the  mountainous  regions  of 
Europe,  by  local  formation  of  clouds  with  profuse  and  perhaps  violent  rains  when  no  general  clouds 
are  formed  and  no  rain  falls  elsewhere.  Such  is,  to  some  extent,  the  case  for  the  whole  of  the  Eocky 
mountains,  and  for  the  higher  mountains  of  the  Great  Basin,  and  of  California  and  Oregon,  But 
there  is  some  value  in  an  illustration  which  expresses  a  rude  average  of  such  results,  and  the  fact 
that  rains  are  profuse  on  the  high  mountains  of  a  district  is  important  to  the  necessities  of  occupation 
and  of  transit,  if  not  to  cultivation.  The  construction  of  tanks  and  reservoirs  which  may  receive 
accumulations  from  such  sources  may  be  resorted  to,  and  irrigation  from  temporary  mountain  streams 
answers  a  valuable  purpose  in  the  existing  cultivation  of  some  localities  of  New  Mexico  and  Sonora. 

The  district  south  of  the  Gila,  including  the  northern  part  of  Sonora,  and  the  recently  acquired 
territory  of  northern  Mexico,  exemplifies  this  feature  in  a  very  striking  manner.  This  region  partici- 
pates in  the  summer  rains  of  Mexico  to  its  extreme  limit  near  the  Gila,  and  sometimes  to  Fort  Yuma, 
The  mountains  in  view  of  this  post  exhibit  frequent  profuse  and  local  rains,  and  these  furnish  supplies

in  otherwise  arid  districts,  of  the  most  abundant  character  for  filling  the  natural  tanks — (tinaja,  alias 
tinajas,  high  tanks,*)  which  exist  there  in  singular  adaptation  to  the  wants  of  the  country.  These 
already  supply  many  uses  in  the  wants  of  surveys  and  expeditions,  and  in  the  actual  occupations  of  a 
permanent  population.  The  clear  atmosphere  preserves  the  waters  so  accumulated  from  the  changes 
they  would  undergo  in  other  climates,  and  they  remain  fresh  until  actually  exhausted  or  evaporated. t 
The  district  known  to  receive  the  greatest  amount  of  this  local  precipitation  in  New  Mexico  has 
been  designated  as  receiving  an  average  of  iifteen  inches  for  the  summer  ;  and  ten,  eight,  and  six 
inches  are  assigned  to  surrounding  districts  of  a  similar  character.  At  some  of  the  posts  very  little 
rain  falls,  and  they  are  usually  located  in  valleys  much  below  the  general  level.  Nearly  all,  how- 
ever, are  in  districts  having  a  medium  fall  of  rain,  and  not  in  the  driest  localities.  Fort  Massachu- 
setts, Santa  F^,  and  others,  are  much  above  the  general  level  of  the  Rio  Grande  valley ;  Albuq^uercLue 
is  in  a  valley  wider  than  usual ;  and  only  Socorro,  Fort  Conrad,  and  El  Paso  represent  the  q^uantity 
in  the  more  immediate  Eio  Grande  valley  with  sufficient  Etccuracy,  The  quantities  of  the  chart  arc, 
therefore,  a  mean  intended  to  represent  the  general  level  as  nearly  as  possible,  and  they  are  neither 
so  much  as  falls  on  the  higher  mountains  nor  so  little  as  the  average  of  the  table  lands. 

The  table  lands  from  the  E.io  Grande  to  the  Colorado  along  the  Gila  river  have  very  little  rain 
in  summer,  and  they  form  the  boundary  between  the  regular  summer  rains  of  northern  Mexico  and 
the  characteristic  summer  rains  of  the  temperate  latitudes.  Some  portion  of  the  mountains  at  the 
north  of  this  river  exhibit  a  frequency  of  rains  nearly  approaching  those  of  Mexico ;  and  at  Fort 
Yuma  the  occurrence  of  rains  in  July  and  August,  after  two  or  three  months  of  absolute  suspension, 
shows  that  the  summer  rains  have  a  partial  development  at  some  seasons  there.  There  is  a  very  little, 
also,  at  San  Diego,  and  on  the  southern  point  of  the  Sierra  Nevada  and  its  prolongations  near  this 
point;  but  in  the  greater  part  of  California  there  is  no  rain  in  the  three  months  of  summer.  There 
is,  apparently,  none  also  in  the  greater  area  of  the  Interior  Basin,  The  wide  desert-reaches 
between  the  Sierra  Nevada  and  the  Colorado  river,  with  the  upper  portion  near  Humboldt 
river,  and  its  extension  southward  east  of  the  Sierra  Nevada  are  known  to  be  nearly  if  not  quite 
destitute  of  rain  at  this  season.  Very  little  is  known  of  much  of  this  great  region,  however,  and 
there  may  be  mountain  ranges,  like  those  of  the  Wahsatch  and  Humboldt  river,  which  have  local 
rains  similar  to  those  of  New  Mexico. 

On  the  Sierra  Nevada  generally  there  is  very  little  rain  in  summer  ;  though  for  this  conclusion  the 
general  impression  derived  from  official  reports,  including  those  of  surveys,  is  the  reliance,  rather  than 
the  positive  record  of  observations  of  this  particular  point.  In  some  instances  personal  observation 
assures  us  that  the  atmosphere  is  remarkably  free  from  clouds  and  all  forms  of  precipitation  at  this 
season.  It  appears  probable  that  none  of  the  mountains  of  California  and  the  coast  precipitate 
any  considerable  quantity  of  rain  in  summer ;  and  the  whole  class  evidently  differs  very  greatly  from 
the  mountains  of  New  Mexico  in  this  respect.  For  other  portions  of  the  year  these  proportions  are 
either  partially  or  wholly  reversed,  as  they  certainly  are  in  the  winter  rainy  season  of  California.

which  cannot  yet  he  properly  presented.  Its  high  mountains  are  generally  more  dry  than  those  of 
Europe,  and  it  is  only  at  the  highest  mountains  of  New  Mexico,  at  eight  to  twelve  thousand  feet 
ahove  the  sea,  that  we  find  rains  similar  to  those  of  the  Pyrenees  and  the  northern  Alps.  The  Italian 
Alps  are  more  ahundant  in  rain  than  any  of  tliis  American  region,  and  there  is  strong  evidence  that 
this  difference  helongs  to  the  general  distrihution,  and  not  to  differences  of  configuration.  The  lati- 
tudes corresponding  to  the  position  of  the  mountains  of  California  and  the  Grreat  Basin  are  found  in 
Africa  and  not  in  Europe,  and  generally  this  helt,  which  is  a  helt  of  calms  at  sea,  is  one  of  desert 
areas  for  the  continents  of  the  northern  hemisphere.  Considered  in  this  light,  the  profusion  on  the 
mountains  of  Hew  Mexico  becomes  exceptional,  though  we  should  find  tlie  analogies  of  Europe  in 
Oregon  and  British  America.  It  is  quite  clear  that  the  profuse  precipitation  characteristic  of  the 
Mississippi  valley  and  Gfulf  coast  in  summer,  does  not  helong  to  the  western  half  of  the  continent, 
irrespective  of  any  causes  in  the  altitude  or  latitude  which  might  diminish  it,  and  that  this  excess  at 
the  east  has  some  local  origin. 

We  know  little  of  the  quantity  of  rain  falling  in  British  America  and  other  parts  of  the  north, 
the  measurement  at  Sitka,  Russian  America,  heing  almost  the  only  one  beyond  the  Canadas.  At 
this  point  the  quantity  of  rain  in  the  summer  and  autumn  is  very  great,  and  from  the  evidences  of 
the  records  of  northern  Oregon  we  may  suppose  the  whole  of  this  coast  to  receive  a  large  precipitation 
in  summer.*  How  far  this  extends  toward  the  interior  is  an  important  point  bearing  upon  the  dis- 
tribution over  the  great  northern  plains  of  the  United  States,  and  for  which  we  have  no  records  north 
of  Forts  Laramie  and  Kearny,  Whether  the  northern  ranges  of  the  Bocky  mountains  interrupt  the 
rains  almost  entirely,  as  they  appear  to  do  in  the  middle  latitudes,  is  not  yet  ascertainable,  and  we 
know  only  that  at  the  Red  river  of  the  North  the  summer  rains  are  abundant.  The  measure  of  ten 
inches  appearing  at  the  extreme  posts  in  that  direction  may  undoubtedly  be  extended  to  Lake  Win- 
nipeg, and  perhaps  to  the  Saskatchewan  valley.  On  the  upper  Missouri,  however,  there  is  known  to 
be  a  great  deficiency  of  rain  in  the  sirmmer  months  at  times,  and  a  large  part  of  the  great  area  par- 
tially enclosed  by  its  long  curve  is  set  down  as  an  arid  and  uncultivable  district  by  explorers.  Its 
amount  of  drainage  is  too  small  to  permit  the  supposition  that  it  is  otherwise,  as  all  the  tributaries  of 
the  Missouri  from  the  west  and  south  below  the  Powder  Horn  river, — or  the  last  of  the  series  near  the 
Yellowstone,  and  of  which  that  river  is  the  principal, — are  small  and  comparatively  unimportant 
streams,  belonging  to  the  class  of  shoal  rivers  of  the  plains,  and  falling  off  to  a  very  small  volume 
in  summer. t 

The  extreme  quantities  of  rain  measured  for  this  season  in  the  various  districts  have  a  great 
range,  and  the  greatest  quantities  found  in  the  tables  are  approximately  placed  on  the  chart.  These 
are  still  more  remarkable  as  departures  from  the  averages  than  the  like  measures  on  the  spring  chart, 
and  it  is  a  characteristic  of  the  climate  that  excessive  falls  of  rain,  with  phenomena  resembling  the 
water  spouts  at  sea,  may  occur  at  any  point  of  the  interior,  and  that  deluges  of  rain  do  frequently 
fall  over  large  districts  as  well  as  at  small  localities  at  this  season.     Near  New  York  twenty  indies

(August,  1843)  have  "been  measured  in  a  single  month  of  summer,  and  the  maximum  of  twenty  inches 
assigned  to  that  vicinity  on  the  chart  is  intended  to  express  a  general  average  rather  than  the  maxi- 
mum observed  at  any  one  point.  A  comparison  of  the  records  at  several  posts  for  any  month  marked 
by  an  excessive  quantity  will,  however,  usually  show  that  the  effect  is  not  confined  to  a  small 
locality.  In  June,  1853,  Forts  Pierce,  Key  West,  and  Myers,  Florida,  have  a  great  quantity  of 
rain — nearly  30  inches  for  the  first,  18  for  the  second,  and  25.5  for  the  last.  At  Fort  Brooke  the 
great  measure  of  54,6  inches  appears  in  the  summer  of  1840,  hut  there  is  no  record  to  compare  with 
south  of  Fort  Monroe,  which  has  30  inches.  At  Fort  Pike  the  maximum  is  53.8  inches;  but,  as  this 
does  not  appear  elsewhere,  the  highest  quantity  at  Baton  Eouge  is  taken  as  the  representative  of  the 
district  generally.  All  the  posts  of  the  Mississippi  valley  show  a  very  high  maximum,  and  this 
extreme  quantity  appears  to  be  directly  associated  with  the  tropical  temperatures  so  frequently  found 
there  for  long  periods  in  summer. 

At  the  lower  point  of  the  coast  of  Texas  the  rainy  smnmer  of  the  east  coast  of  Mexico  approaches 
both  the  arid  summer  of  New  Mexico  and  upper  Texas,  and  the  equally  distributed  rains  of  the  east- 
ern United  States,  which  extend  over  a  large  share  of  Texas.  At  the  lower  Eio  G-rande  the  records 
of  1850  to  1852  would  show  a  greater  identity  with  New  Mexico  than  with  either  of  the  other  dis- 
tricts ;  but  in  the  records  subsequent  to  that  time,  and  particularly  for  so  much  of  1855  as  has  been 
observed,  the  leading  characteristics  are  those  belonging  to  the  coast  at  Tampico,  or  to  New  Orleans 
in  a  wet  year.  This  result  places  the  locality  in  its  most  natural  association,  and  shows  that  it  may 
have  a  considerable  range  of  climate,  at  times  identiiied  with  that  of  each  of  the  three  on  which  the 
district  borders.

DISTRIBUTION  OF  PRECIPITATION  FOR  THE  AUTUMN. 


For  the  area  wlioio  the  graphic  illustration  of  rain  distribution  is  most  clearly  expressive  of  the  actual 
condition — that  east  of  the  Rocky  mountains — there  is  less  contrast  in  the  quantities  for  the  various 
districts  in  this  than  in  any  other  season,  orperiod  of  three  months.  The  measure  of  ten  inches,  which 
is  so  general  for  all  the  charts  on  the  Atlantic  coast,  belongs  to  a  much  larger  proportion  of  this  area 
than  in  other  caseSj  and  there  are  hut  two  or  three  small  districts  having  larger  measures.  The 
three  warmer  points  of  the  Gulf  coast  which  are  half  tropical,  and  which  so  uniformly  have  a  large 
precipitation  for  some  part  of  the  year,  all  now  go  nearly  as  high  as  fifteen  inches,  though  the  records 
of  southern  Florida  and  of  the  posts  near  New  Orleans  are  for  imperfect  periods.  At  the  mouth  of 
the  Rio  Grande  the  q^uantity  is  clearly  greater  than  at  any  other  season,  and  this  appears  to  be 
caused  by  an  extension  of  the  rainy  season  of  summer  into  September  and  October,  or  rather  by  its 
occurrence  at  that  point  in  these  months  principally,  instead  of  being  confined  to  the  summer  months 
proper,  as  in  some  parts  of  Mexico.  On  all  the  eastern  coast  of  Mexico  September  is  one  of  the  rainy 
months,  and  at  Vera  Cruz  the  (Quantity  falling  in  it  is  nearly  as  great  as  in  any  other  month.*  This 
development  of  the  rainy  season  is  confined  to  the  coast,  however,  and  it  is  only  at  Fort  Brown  and 
Corpus  Christi  that  it  may  be  identified  as  having  any  features  not  common  to  the  ecLually  distributed 
rains  of  the  Mississippi  valley. 

On  the  coast  of  Oregon  the  periodical  rains  occupy  a  large  share  of  the  three  months,  beginning 
before  the  close  of  September  and  becoming  quite  continuous  through  the  latter  part  of  October  and 
in  November.  At  two  posts  of  the  immediate  coast.  Fort  Orford  and  Astoria,  the  quantity  is  twenty 
inches,  and  at  the  partially  interior  post  of  Steilacoom,  fifteen  inches.  At  Sitka  the  mean  for  two 
years  is  thirty-four  inches,  and  it  is  evident  that  the  humidity  increases  rapidly  along  the  whole  coast 
from  California  northward.  The  periods  are  not  sufficient  to  give  reliable  mean  quantities,  however, 
and  it  can  only  be  generally  stated  that  the  Pacific  coast  north  of  42°  of  latitude  is  characterized  by 
profuse  precipitation  through  at  least  half  of  the  three  months  of  autumn. 

The  districts  deficient  in  rain  at  tliis  season  are  nearly  the  same  as  at  other  seasons.     The  plains,

750  REPORT. 

with  New  Mexico,  the  Great  Basin,  and  California  are  all  comparatively  dry.  In  California  generally 
there  is  no  rain  in  September,  and  foe  all  parts  south  of  San  Francisco  none  in  Octoher.  In  this 
northern  half  the  rains  commence  in  Octoher,  though  irregularly,  and  in  the  south  in  like  manner  in 
Novemher.  In  California  these  rains  are  rarely  continuous  for  these  months,  however,  or  reliable  in 
successive  years.  They  sometimes  commence  in  the  form  of  the  more  perfectly  developed  periodical 
rains  of  the  northern  coast,  or  of  this  district  for  Decemhev  and  March,  yet  they  may  be  as  extremely 
irregular  as  in  any  other  part  of  the  United  States.  If  the  distinction  of  this  seaaon  were  there  the 
same  as  it  substantially  is  for  the  eastern  United  States,  ot  that  of  declining  temperatui'e  and  the 
cessation  of  vegetable  growths,  there  would  be  an  almost  entire  absence  of  rain  belonging  to  it  over 
the  great  interior  and  California  districts.  The  heat  of  summer  is,  in  fact,  the  close  of  vegetation  for 
most  of  this  region  because  of  its  aridity,  and  the  autumn  has  little  in  common  with  that  of  the 
Atlantic  States. 

In  the  Great  Basin,  or  in  its  best  known  portion  near  Salt  Lake,  and  in  New  Mexico,  the  rains 
of  these  three  months  are  quite  equally  distributed,  and  the  actual  quantities  do  not  differ  greatly 
from  those  at  other  seasons.  The  snows  are  early,  also,  occurring  quite  as  soon  as  in  the  lake  district 
of  the  east,  though  their  quantity  is  unimportant  except  in  the  highest  mountain  ranges.  This 
district  has  some  forms  of  precipitation,  either  as  cloud  formation  alone,  or  as  slight  stonns  of  rain  or 
snow  on  the  mountains,  during  most  of  the  period  of  these  months  ;  and  though  practically  dry,  as 
every  season  except  summer  is,  it  is  so  only  by  general  deficiency  of  atmospheric  moisture,  and  not  in 
consequence  of  any  periodical  distribution,  This  portion  of  the  interior  is,  technically,  a  district  of 
constant  precipitation. 

On  the  plains  the  distribution  of  rain  is  somewhat  the  same  as  in  the  first  two  months  of  spring  in 
respect  to  the  frequency  of  long  periods  of  fine  weather,  and  in  the  generally  small  quantity  falling. 
The  autumnal  periods  of  absence  of  rain  are  longer,  however,  and  more  general,  reaching  eastward 
over  most  of  the  Atlantic  States,  and  sometimes  characterizing  nearly  the  whole  area.  The  softened 
temperature  and  peculiar  character  of  these  dry  autumnal  periods  form  one  of  the  most  striking 
features  of  contrast  with  the  same  season  in  Europe,  and  these  peculiarities  almost  always  continue 
until  broken  up  by  a  general  rain.  The  steady  atmospheric  movement  from  the  west  which  belongs 
to  the  middle  latitudes  of  the  United  States,  apparently  favort.  the  extension  of  these  periods  both  in 
time  and  space.  Dry  and  serene  periods  on  the  plains  become  even  more  dry  and  serene  as  the  mass 
of  atmosphere  moves  eastward  at  this  season,  and  the  changes  of  temperature  are  not  only  less,  but 
there  is  also  less  rain  to  be  precipitated  by  these  changes. 

These  dry  periods  are  fewer  east  of  the  plains,  and  the  number  of  days  on  which  rain  or  snow 
falls  increases  toward  the  Atlantic  coast.  Their  characteristic  features,  as  shown  in  the  calms  of 
several  days  continuance  popularly  known  as  the  Iv/Uan  summer,  are,  however,  still  well 
defined,  particularly  in  central  New  York  and  Canada ;  but  they  are  shorter,  and  they  alternate 
with  intervals  of  slow  but  constant  rains,  embracing  many  successive  days. 

In  most  of  the  Atlantic  States,  and  particularly  in  the  central  districts,  or  from  New  York  to 
Norfolk,  the  precipitation  of  autumn  is  mainly  in  general  storms  of  two  or  three  days'  duration.  The 
number  of  days  of  rain  is  less  than  at  the  northeast,  and  the  intervals  are  usually  serene.  The  actual 
depth  of  water  falling  is  strikingly  regular  for  the  successive  days  throughout,  as  before  remarked,  and 
the  proportion  for  each  of  the  months  quite  uniform.  There  is  some  appearance  of  deficiency  in 
September  for  part  of  the  northern  districts,  as  at  the  military  posts  of  the  New  England  States  ;  but 
the  most  extended  periods  of  record  from  other  sources,  as  at  New  Bedford ,   Massachusetts ;  Albany,

Utica  and  Rochester,  New  York ;  as  well  as  tlie  very  complete  p 
&c.,  show  no  noticeable  diminution  for  this  month.  There  is  j 
point  north  of  Fort  Monroe  in  the  eastern  States. 

The  autumnal  distribution  of  rain  in  Florida  is  more  difficult  of  explanation  than  that  for  any 
other  district,  from  its  very  great  irregularity,  and  from  the  inadequacy  of  the  periods  of  time  during 
which  ohservations  have  been  made  to  reduce  the  prominence  of  the  differences  arising  from  this 
irregularity,  and  to  establish  any  definite  rule  of  the  relations  of  the  several  months.  The  distribution 
at  the  posts  of  the  south,  in  the  Carolinas  and  Georgia,  is  also  extremely  irregular,  and  it 
appears  that  the  non-periodic  variations  are  greater  here,  in  regard  to  the  quantity  of  rain  in 
these  months,  than  almost  anywhere  else.  The  regular  distribution  of  quantities  at  Fort 
Monroe  becomes  much  broken  up  at  Fort  Moultrie,  where  each  of  the  autumn  months  frequently 
falls  off  to  an  almost  entire  absence  of  rain.  The  mean  of  September  is  here  also  much  the 
greatest,  and  that  for  November  least.  At  Savannah,  Oglethorpe  barracks  gives  the  same  result, 
and  a  series  of  fourteen  years'  observation  at  Savannah,  by  Dr.  Posey,*  is  quite  the  same  in  its 
distribution.  Nearly  all  the  posts  of  eastern  Florida,  and  of  the  peninsula,  give  a  like  result ;  and 
a  tendency  to  periodicity,  or  to  a  division  of  seasons  in  this  respect,  is  certainly  apparent  for  these 
short  periods.     The  following  numljers  illustrate  this  point :

From  these  results  it  is  evident  that  a  comparatively  dry  season  succeeds  the  profuse  rains  of 
t  and  September  in  Florida,  and  the  portion  of  the  Atlantic  States  bordering  it,  and  also  that 
this  does  not  extend  westward  as  far  as  Pensaoola.  The  periods  at  this  point,  and  at  Mobile,  (Mount 
Vernon  Arsenal,)  are  for  ten  to  fifteen  years  each  ;  and  if  the  features  there  were  really  analogous  to 
those  of  eastern  Florida,  the  fact  could  not  fail  to  appear  in  the  comparison  of  the  similar  dates 
embraced  by  these  records. 

By  reference  to  the  general  tables  it  will  be  seen  that  there  is  a  marked  tendency  toward  the 
development  of  a  winter  dry  season,  even  in  the  States  next  to  Florida,  and  that  in  southern  Florida 
this  is  quite  decided  and  almost  as  fully  developed  as  in  the  recognized  tropical  climates.     As  before

remarked,  however,  there  are  great  irregularities,  and  often  quite  contradictory  results  for  single  years. 
Thus,  at  Fort  Moultrie  there  is  one  instance  of  near  eight  inches  of  rain  in  October;  at  Oglfethorpe  barracks 
and  Fort  Marion  instances  of  sis  inches  ;  at  Fort  Pierce,  ten  ;  at  Key  West  one  of  nine  and  one  of 
fourteen.  The  f|;uantities  iu  November  are  also  often  considerable,  and  all  these  alternate  with  months 
of  none  or  of  very  little.  In  September  these  instances  of  profuse  rains  are  more  numerous  and  more 
extreme,  in  some  cases  exceeding  twenty  inches.  The  most  prominent  feature  of  rain  distribution  in 
Florida,  in  distinction  from  other  pai'ts  of  the  United  States,  is  this  great  irregnlarity,  which  prevents 
us  from  getting  clear  general  views  from  periods  of  record  embracing  but  two  or  three,  or  a  few  years. 
The  records  at  Pensacola  (Fort  Barrancas)  and  at  Mobile  are  also  characterized  by  great  irregu- 
larities, and  here  a  winter  r<dny  season  is  in  process  of  development.  The  minimum  is  in  August, 
September,  or  October,  from  which  point  the  cLuantitiea  increase  very  much  in  November  in  every 
case,  remaining  large  through  every  winter  month.  Comparing  Baton  Eouge,  as  the  central  point 
of  this  district  of  profuse  winter  rains,  with  the  posts  of  southern  Florida,  the  contrast  is  at  once 
apparent.  Though  this  belongs  more  appropriately  to  the  winter  distribution,  a  citation  may  he 
made  here  to  illustrate  the  characteristics  of  the  autumn,  in  which  season  these  changes  first  occur.

The  first  approach  to  this  dry  season  in  Florida  is  made  in  October,  and  from  the  minimum, 
which  appears  to  occur  in  November,  there  is  a  partial  resumption  of  the  rains  apparent  in  mid- 
winter, to  be  followed  by  other  months  of  less  rain.  But  a^  a  whole,  the  winter,  from  October 
forward,  is  a  dry  season  on  the  peninsula  of  Florida,  and  to  some  extent  on  the  south  Atlantic  coast. 
At  the  west,  along  the  G-ulf  coast,  however,  a  reverse  condition  obtains,  and  a  rainy  season  of  the 
most  marked  features  belongs  to  the  vicinity  of  the  lower  Mississippi,  apparently  reaching  up  in  the 
interior  to  Memphis.* 

Tho  irregularities  in  this  succession  of  the  months  are  not  sufficient  to  change  the  character  of 
this  district  as  one  of  constant  precipitation,  however,  nor  is  it  rigidly  any  the  less  identified  with 
that  of  equally  distributed  rains  in  the  general  sense  in  which  the  term  is  used.  But  in  Florida  a 
different  designation  applies,  though  we  are  yet  unable  to  say  precisely  what  that  designation  should 
be.  It  appears  to  be  a  climate  ordinarily  of  a  division  into  two  principal  seasons  in  regard  to  the 
rains,  the  wet  summer  and  the  dry  winter,  yet  either  may  he  interrupted  by  extremes  of  an  opposite 
character  much  greater  than  those  occurring  in  any  other  known  district. 

The  proportion  of  the  autumnal  precipitation  which  falls  in  snow  is  CLuite  large  for  some  part  of 
the  northern  and  eastern  United  States,  and  for  the  mountainoi^  regions  of  the  interior  and  Pacific 
coast.     Snows  occur  in  rare  instances  north  of  42°  of  latitude  in  September ;  in  October  they  are

fi-ecLuent  to  this  point,  and  they  may  reach  to  the  38th  parallel.  In  November  they  rarely  go  much 
farther  south,  but  they  remain  upon  the  ground  in  the  more  northern  districts,  and  sometimes  as  far 
south  as  the  first  named  latitude,  through  much  of  the  winter.  The  elevated  districts  near  the 
lakes  and  toward  the  Atlantic,  as  in  the  highlands  of  New  York  and  New  England,  are  most 
abundant  in  snow  ;  and  the  CLuantity  of  precipitation  is  maintained  in  this  form  through,  the  winter 
months  here,  while  it  appears  to  fall  off,  from  deficiency  of  atmospheric  moisture,  west  of  the  lakes 
and  on  the  great  plains.  At  Fort  Snelling  November  has  only  about  one-third  as  much  as  Septem- 
ber, while  at  Fort  Brady  there  is  much  less  difference,  and  at  Madison  Barracks  (Sacketfc's  Harbor) 
and  XJtica,  New  York,  there  is  no  difference  in  the  quantities. 

There  are  too  few  observations  to  warrant  any  examination  of  the  quantity  of  snow  in  the  great 
mountainous  districts  of  the  interior  and  Pacific  slope,  and  the  illustrations  of  the  chart  for  those 
districts  are  approximations  only,  derived  from  such  observations  as  exist,  and  from  the  best  analo- 
gies afforded  by  the  configuration.

DISTRIBUTION  OF   PliEOIPITATION  IN  EAIN  AND  SNOW  TOE  THE  WINTEE. 


The  general  influence  of  temperature  on  the  quantity  of  water  falling  in  rain  and  enow  becomes 
most  fully  developed  in  the  winter  precipitation  of  the  interior,  where  it  is  evident  that  helow  a 
certain  point  of  temperature  very  little  moisture  remains  in  the  atmosphere,  and  the  quantity  falling  in 
rain  and  snow  is  very  small.  The  measurements  for  this  interior  are  too  few  to  give  the  absolute  mean 
quantities  here  with  precision,  but  they  cannot  vary  much  from  those  entered  on  the  chart.  At  Fort 
Snelling  the  period  is  sufficient  to  give  a  very  reliable  result,  however,  and  those  at  Ports  Leaven- 
worth, Kearny,  and  Laramie  cannot  be  far  from  true  mean  quantities.  North  of  this  line,  on  the 
plains,  it  is  only  known  that  the  winter  precipitation,  in  every  form,  becomes  gradually  less,  and  it 
is  thought  to  be  least  on  the  plains  of  the  upper  Missouri. 

In  illustration  of  this  general  feature  of  very  little  interior  precipitation  in  winter,  comparison 
with  the  interior  districts  of  Siberia  may  be  mside,  and  on  these  last  the  rate  of  diminution  on  any  line 
from  western  Europe  is  found  to  be  very  rapid,  and  the  extreme  point  of  the  interior  to  have  very 
little,  if  not  to  be  quite  destitute  of  winter  precipitation.  Such  a  district  of  absolute  aridity  is  said 
to  exist  there,  and  in  referring  to  the  climatology  of  the  plains  of  British  and  Russian  America,  Eich- 
ardson  cites  it,  and  remarks  a  possibly  parallel  case  near  the  Yukon  river,  at  the  western  limits  of 
British  America.     It  is  here,  as  in  Asia,  a  barren  plateau  oa  which  no  water  is  found.* 

The  quantity  of  snow  is  small  on  all  the  northern  prairie  slope  of  the  Eocky  mountains,  and  the 
prairies  of  the  Saskatchewan  and  upper  Missouri,  in  a  line  with  Fort  Union,  (of  the  Missouri,)  Fort 
Pierre,  and  Fort  Kearny,  appear  to  aiford  the  minimum  of  winter  precipitation  in  every  form.  The 
snows  are  more  abundant  at  theEedEiver  of  the  North  than  west  of  it  on  the  plains,  and  as  the  lake 
district  is  traversed  from  the  west  they  steadily  increase,  with  the  occasional  occurrence  of  profuse 
winter  rains,  to  the  Atlantic  coast.  Through  all  this  lake  district,  with  that  of  the  northern 
Atlantic  coast,  rains  and  snows  are  interspersed  through  all  the  winter  months,  and  the  changes  of 
temperature  are  such  as  sometimes  to  render  these  rains  as  profuse  as  those  of  any  other  season. 
Winter  rains  are  more  rare  on  the  plains,  in  the  same  latitudes,  though  not  wholly  wanting,  except, 
perhaps,  near  Lake  Superior,  on  the  west  and  northwest,  Here  the  winter  is  quite  uniform  and 
rigid,  and  it  is  characterized  by  great  aridity,  as  well  as  by  steady  low  temperature.f 

As  an  associated  general  feature  of  the  chart  the  appearance  of  the  greater  shadings  on  the  ocean 

*  "  Between  the  Yukon  and  Lewis  rivers  there  is  a  barren  plateau  which  the  Indiajis  croaa  in  four  daja,  but  on  wliicli  they  find  no 
water  ;"  and  in  a  note  its  Kimilarity  to  that  in  Siberia  is  remarked,  "for  it  can  scarcely  he,  in  so  rigorous  a  climate,  that  melting  snow, 
if  it  exists,  should  not  leave  pools  of  water  all  tlio  summer." — RUhardson's  Arctic  Expedition. 

t  Richardson  nialt-es  frequent  referenco  to  the  "dead  winter  months  "at  the  Hudson's  Bay  Company's  posts  of  British  America, 
beyond  the  lake  district.  At  Penetanguisliene,  Lalte  Huron,  he  says  ;  "In  December  much  enow  fells.  A  great  fall  of  snow  toies 
place  in  February,  and  there  is  usually  a  temporary  Ihaw  about  the  end  of  the  month,  accompanied  by  heavy  rain  and  ooeasionally  by 
ihander."  Of  the  winter  in  Minnesota  a  recent  writer  says,  (Bond's  Minnesota  and  its  Resources:)  "The  most  remarkable  charac- 
teristic of  the  winter  climate  of  Minnesota  is  its  great  dryness — there  being  an  almost  total  absence  of  rain  and  moisture.  Not  more 
than  ono  heavy  rain  storm  has  occurred  within  its  limits  during  the  last  ten  years."

coasts  is  qixite  conspicuous  in  wiatei,  though  there  is  one  exception,  which  has  "been  noticed  in 
comparing  tlie  quantities  for  the  autumn,  in  the  diminished  quantities  in  Florida  and  the  south 
Atlantic  States.  This  winter  dry  season  appears  also  in  lower  Texas.  The  greater  quantities  on 
the  coasts  at  this  season,  afford  the  only  features  of  identity  of  the  distribution  of  rain  on  this 
part  of  the  continent  with  that  characteristic  of  Eiu-ope,  and  that  wMcli  has,  hitherto,  as  in  Berg- 
haus'  and  Johnston's  chaits,  been  assigned  to  this  continent  from  the  analogies  afforded  hy  better 
known  land  areas.  It  h*i^  been  seen  how  largely  the  distribution  for  the  seasons  already  illustrated, 
differed  from  that  based  on  prmciples  which  assign  to  coasts,  and  to  the  nearest  mountain  ranges, 
the  leading  agency  m  causing  precipitation.  In  previous  cases,  the  Alleghanies  more  frequently 
cause  deficiency  than  excess,  and  now,  although  the  districts  near  the  coast  have  more  rain  than  the 
interior,  there  still  appeais  to  be  no  increase  dne  to  the  presence  of  any  of  the  elevations  of  the 
Appalachian  chain.  Upper  Viiginia  contrasts  with  the  Ohio  valley,  and  with  the  plain  at  Baltimore 
and  Norfolk,  in  the  same  manner  as  in  summer,  though  not  to  the  same  degree.  At  the  first 
uplifts  of  the  southern  extremity  of  these  hills,  in  Alabama  and  Mississippi,  there  may,  however,  be 
some  increase  in  the  quantity  of  rain,  though  we  are  yet  unable  to  decide  the  point  satisfactorily. 

The  maximum  for  the  eastern  United  States  falls  again  in  the  atmospheric  basin  of  the 
lower  Mississippi,  and  where  a  partial  development  of  a  winter  rainy  season  occurs.  In  the 
remarks  relating  to  the  autumn  precipitation  these  winter  rains  and  their  partial  periodicity 
were  noticed.  The  contrast  with  Florida  and  lower  Texas  which  they  exhibit  is  perhaps  the 
most  striking  peculiarity  disclosed  by  the  chart,  or  by  the  illustration  of  the  observations.  It  is 
difficult  to  account  for  these  features  satisfactorily  upon  any  received  principles  of  winter  distribution 
of  atmospheric  humidity,  unless  wc  suppose  these  extreme  southern  points  to  be  more  nearly 
assimilated  to  tropical  districts  in  regard  to  rain  than  they  are  in  temperature.  In  truth,  they  lie  in 
the  neutral  latitudes,  which  afford  the  anomalies  of  Africa  and  Asia,  and  which  appear  to  be 
controlled  by  the  configuration  of  the  districts,  and  by  accidental  or  anomalous  atmospheric  move- 
ments resulting  from  peculiar  relations  of  the  sea  and  land  areas.  The  profuse  rains  and  the 
partial  rainy  season  of  winter  are  extended  up  the  valley  of  the  Mississippi  for  a  considerable 
distance,  and  so  much  as  to  induce  the  impression  that  there  is  an  atmospheric  eddy  or  basin 
here,  in  which  general  circulation  ceases,  and  the  conditions  most  favorable  to  accumulation  of 
moisture  and  to  profuse  precipitation  are  found.  The  questions  presented  by  this  constant  concen- 
tration of  the  areas  of  maximum  precipitation  in  the  basin  of  the  lower  Mississippi  are  worthy  a  more 
thorough  analysis  than  can  now  be  made. 

5  to  the  districts  of  most  profuse  winter  rain  on  the  Pacific  coast,  we  find  the  European 
s  fully  sustained,  and  results  quite  similar  to  those  of  the  west  coasts  of  the  British  islands 
and  Norway.  For  the  lower  latitudes,  or  in  California,  the  humid  atmosphere  has  considerable 
elevation,  and  the  rains  are  not  wholly  arrested  by  the  lofty  chain  of  the  Sierra  Nevada,  and  at  the 
same  time  they  are  not  extraordinarily  profuse  at  and  near  the  level  of  the  sea.  In  Oregon  they  are 
more  low  and  local,  falling  very  profusely  at  sea  level  and  on  the  low  coEist  ranges.  No  very  large 
quantity  remains  to  be  arrested  by  the  range  of  Eocky  mountains,  though  these  are  so  high  as  to 
nearly  exhaust  the  moisture  not  deposited  near  the  coast,  and  to  receive  a  large  quantity  of  snow  in  the 
whole  course  of  the  cold  season.  At  Astoria  the  quantity  of  winter  rain  is  much  like  that  of  Bergen,  in 
Norway,  which  at  60°  north  latitude  has  a  mean  of  23.5  inches  of  rain  in  winter  for  a  period  of  ten 
years.  Points  of  the  west  coast  of  Ireland,  and  of  Scotland  and  parts  of  England,  would  not  differ 
largely  from  these  measures.     Bergen  is  considered  as  the  most  extremely  rainy  of  European  positions

in  its  winter  climate,  and  it  is  probable  that  the  quantity  placed  on  the  chart  for  onr  immediate  -western 
coast — thirty  inches — is  too  great  to  be  sustained  by  the  results  of  a  period  of  years.  At  Sitba  the 
mean  of  two  years  is  but  sixteen  inches,  and  at  Steilacoom  that  of  five  years  ia  21.5.  The  mean 
for  the  most  exposed  points  of  the  coast  cannot  be  less  than  25  inches,  and  this  quantity  probably 
belongs  to  the  whole  coast,  at  least  as  far  as  Sitka. 

In  Norway  the  existence  of  abrupt  mountains  near  the  coast  renders  the  comparison  of  interior 
districts  similar,  and  a  dry,  cold,  and  unproductive  region  exists  there  lihe  much  of  British  America, 
but  in  other  parts  of  Europe  the  humid  atmosphere  of  the  coasts  reaches  far  inland,  adding  largely 
to  the  winter  precipitation,  and  softening  the  climate  in  regard  to  temperature  in  a  corresponding 
degree.  None  of  the  Pacific  districts  afford  these  advantages  hero,  and  thus  at  all  seasons  the  interior 
districts  of  Oregon,  with  those  of  the  plains  of  the  Columbia,  of  the  Ureat  Basin,  and  of  California, 
are  found  to  be  characterized  by  like  conditions  of  aridity,  and  by  similar  extremes  and  transitions 
of  temperature.  All  this  chain  of  basins  and  plateaux  is  alike  in  this  respect,  and  its  great  area  and 
peculiar  position  requires  a  considerable  extension  of  posts  of  observation  to  define  its  climate  with  the 
req^uisite  precision  for  all  the  purposes  of  occupation  and  transit. 

The  precipitation  of  the  great  Rocky  mountain  ranges  in  winter  can  only  be  stated  with  a  remote 
approximation.  It  does  not  appear  that  the  snows  are  remarkable  for  profusion  at  this  season,  and 
the  great  accumulations  found  by  those  who  have  attempted  to  traverse  the  mountains  in  any  part  of 
the  cold  season  do  not  necessarily  imply  very  deep  falls  in  winter  for  the  general  sur&ce.  As  all  the 
precipitation  from  October  to  the  close  of  May  is  retained  on  the  mountains  in  the  form  of  snow,  the 
floods  of  June  would  be  large  if  the  quantity  were  quite  moderate  in  each  month,  and  the  general 
systems  of  drainage  are  not  adequate  to  carry  off  the  measure  of  rain  and  snow  which  falls  on  the 
mountains  of  the  New  England  States.  Assuming  for  the  Rocky  mountain  region  a  winter  precipi- 
tation equivalent  to  five  inches  in  depth  of  rain^  the  rule  of  reduction  of  snow  to  water  applicable 
in  cold  climates,  of  one  inch  of  water  to  twelve  of  snow,  would  give  sixty  inches  of  snow  for  the 
winter  fall.  As  most  of  the  precipitation  of  spring  and  autumn  is  also  in  snow,  we  may  suppose  an 
equal  quantity  in  spring  and  half  this  depth  in  autumn — the  whole  giving  twelve  and  a  half  feet  of 
loose  snow  as  falling  in  the  whole  cold  season  on  the  higher  ranges.  The  quantity  can  scarcely  be 
greater  than  this  anywhere,  and  its  average  is  probably  less. 

The  measurement  of  snows  in  their  depth  when  first  fallen  has,  unfortunately,  received  little 
attention  in  these  military  records,  while  attention  to  the  melting  of  the  quantity  and  its  measurement 
as  water  has  oeen,  on  the  whole,  very  accurately  and  carefully  given.  The  practical  value  of  a  com- 
parison of  the  mean  quantities  of  loose  snow  is  now  very  great,  since  general  routes  of  transit  must 
be  controlled  by  such  considerations  in  forming  connections  with  the  Pacific  States.* 


*  The  valuable  tables  now  published  regularly  for  many  years  in  the  Amirican  Ahaanac  afford  the 
quantity  of  snow,  and  some  of  these  I'osults  may  be  given  for  their  general  intoreEt.

IVIEAN  ANNUAL  DISTRIBUTION  OF  PEECIPITATTON. 


The  summary  of  the  quantities  for  the  several  seasons  in  mean  quantities  for  the  year,  exhibits  a 
more  symmetrical  distribution  of  precipitation  than  belongs  to  either  of  the  first  charts.  The  results 
are  believed  to  be  less  liable  to  error  from  imperfection  of  periods,  and  from  the  great  range  of  non- 
periodic  variations,  than  in  the  case  of  periods  embracing  but  a  part  of  the  year.  This  conclusion  is 
based  on  the  assumption  that  the  non-periodic  variations  in  the  quantity  of  water  falling  in  rain  do 
not  cover  so  much  time,  and  that  the  compensating  extremes  are  more  likely  to  return  within  the 
year  than  to  be  deferred  to  subsequent  years.  It  is,  however,  scarcely  possible  to  decide  this  point 
from  the  existing  records,  as  in  several  of  the  more  complete  series  there  are  years  known  to  possess 
constant  errors  of  measurement,  either  in  excess  or  in  deficiency. 

The  general  features  of  symmetry  are,  first,  the  great  quantities  in  the  lower  Mississippi  valley 
and  the  Gulf  States  ;  nest  the  comparatively  large  quantities  and  gradual  out-shadings  of  other  parts 
of  the  Mississippi  valley ;  the  uniform  measures  of  the  Atlantic  coast  throughout ;  and  the  imiform 
and  decreasing  quantities  from  this  district  to  the  higher  districts  of  the  whole  Alleghany  range,  and 
still  more  to  the  lake  district — which  last  is  also  quite  uniform  throughout.  The  falling  off  on  the 
northern  portion  of  the  plains  is  quite  abrupt,  and  not  only  the  very  complete  series  at  I"ort  Snelling 
60  far  establishes  this  point,  but  such  partial  records  as  are  obtainable  from  positions  near  that 
post,  and  the  features  universally  ascribed  to  the  vicinity  of  Fort  Pierre,  confirm  it.  The  plains 
are  quite  symmetrical  in  their  quantities  beyond  this  point,  so  far  as  may  be  ascertained,  and  the 
valley  of  the  lower  Eio  G-rande  appears  to  correspond  very  well,  and  to  continue  this  symmetry  of 
the  yearly  results.  Beyond  the  plains  the  characteristic  features  of  the  districts  of  periodical  rains 
are  strikingly  exhibited,  and  southern  Florida  gives  strong  evidence  that  it  should  be  identified  with 
the  districts  of  periodical  rains,  rather  than  with  the  area  of  constant  precipitation  of  the  eastern 
United  States.  There  are  fewer  irregularities  in  these  annual  summaries,  however,  than  in  the 
sums  for  separate  seasons,  and  the  possibility  of  making  an  illustration  of  sufficiently  precise  and 
practical  value  would  not  be  doubted  in  regard  to  these  quantities. 

In  comparing  this  illrmtration  with  the  charts  of  Eerghaus  and  Johnston,  the  deficiency  on  the 
coasts  of  the  Atlantic  and  Gtulf  States  is  quite  apparent.  The  gradations  increase  toward  the  interior, 
instead  of  diminishing,  on  any  parallel  from  the  Atlantic  coast  toward  the  Mississippi  valley,  at  least 
as  far  north  as  43°  of  latitude,  and  above  this  parallel  there  is  but  a  slight  extension  of  a  district  of 
greater  precipitation  on  the  Atlantic  coast.  From  the  Gulf  coast  northward  there  is  also  a  decided 
increase  at  some  points,  and  for  a  moderate  distance ;  as  also  from  the  coast  at  St.  Augustine,  (Fort 
Marion,)  Florida,  northwestward  toward  the  interior  of  Georgia.  The  Pacific  coast  has  the 
analogies  heretofore  attributed  to  all  temperate  climates,  but  they  are  there  greatly  exaggerated  in 
quantity  for  the  northern,  and  diminished  for  the  southern  portions.  The  prominent  deduction 
derived  from  this  feature  giving  the  greatest  quantities  in  the  interior  for  the  eastern  United  States, 
and  from  the  uniformity  of  the  quantities  over  large  districts  and  their  extraordinary  symmetry,  is, 
that  the  supply  of  moisture  for  precipitation  is  from  remote  sources,  and  that  the  immediate  indjiging

causes  are  not  found  in  the  configuration  of  the  country.  If  the  altitude  of  the  hiUs  and  mountains 
of  this  part  of  the  continent  haa  any  agency  in  inducing  precipitation,  we  should  find  interruptions 
in  the  aymmetry  due  to  thenij  and  an  irregularity  conforming  to  their  irregularities  of  position. 
This  would  he  more  apparent  if  their  effect  were  supposed  to  be  to  increase  the  amounts,  as  is 
generally  the  case  elsewhere,  than  if  they  had  a  negative  relation  to  them,  or  one  tending  to 
diminish  the  measures.  The  last  is,  in  truth,  to  some  extent  the  real  relation  of  the  districts  having 
considerable  altitude,  if  not  of  the  sharper  elevations  and  mountains  themselves,  to  the  (Quantity  of 
water  falling  in  the  vicinity  of  the  AUeghanies  ;  though  such  a  relation  cannot  be  considered  in  the 
same  sense  as  one  of  increased  quantities,  since  it  is  merely  an  interruption  of  the  uniformity  which 
would  appear  if  the  whole  were  a  plain. 

Ey  comparison  of  the  hyetal  with  the  thermal  condition  for  this  area,  we  may  see  a  similarity 
which  may  solve  the  questions  indicated  in  the  contrasts  just  noted.  East  of  the  plains  the  shadings 
conform  to  the  curvatures  of  the  thermal  lines,  and  this  in  a  striking  manner,  if  we  take  the  thermal 
chart  for  the  summer,  in  which  season  the  excesses  principally  fall.  The  higher  temperatures  then 
fall  inland,  even  for  all  the  southern  coasts ;  and  the  great  heats  of  the  Mississippi  valley,  the  reces- 
sion of  the  lines  ahout  the  lake  district  and  ahout  the  Alleghany  mountains,  the  heat  of  the  interior 
of  southern  Florida,  and  many  other  points  of  correspondence,  indicate  clearly  the  existence  of  definite 
and  necessary  relations  of  these  two  conditions  for  the  district  under  consideration.  The,  guaniity  of 
water  precipitated  in  rain  is  proportioned  to  the  temperattire,  mid  not  to  aMfigurati/m,  or  to  proximity  to 
(he  sea. 

To  this  general  principle  there  arc  partial  exceptions,  one  of  which  lias  been  mentioned  in  the 
extension  of  the  heavy  shading  on  the  northern  coast  of  New  England.  This  district,  including  the 
highlands  and  mountains  of  most  parts  of  the  New  England  States  and  New  York,  has  more  rain 
than  would  fall  to  it  by  the  general  rule ;  and  there  is  some  evidence  that  the  contact  of  atmospheric 
volumes  with  those  altitudes  induces  a  share  of  the  precipitation,  ae  in  Europe  and  on  the  Pacific 
coast.  The  next  exception  is  in  the  lower  part  of  the  lake  district,  the  vicinity  of  Lake  Ontario  in 
New  York.  Here  the  temperature  is  highest,  and  the  quantity  of  rain  is  least  for  its  latitude,  except, 
perhaps,  the  vicinity  of  Lake  Michigan,  on  both  sides.  As  the  basin  of  Lake  Ontario  is  some 
hundreds  of  feet  below  the  greater  part  of  the  lake  district,  the  exception  is  more  apparent  than  it 
otherwise  would  be;  and  the  absence  of  the  greater  quantities  which  should  he  found  there,  if  the 
latitudes  were  lower,  shows  only  that  the  northern  limit  of  this  distinctive  district  is  nearly  attained, 
and  that  it  would  not  exclusively  belong  to  latitudes  as  high  as  45  degrees.  The  profuse  rains  of  the 
St.  Lawrence  valley  and  basin,  however,  still  in  a  great  measure  confirm  the  general  principle,  and 
associate  a  large  proportion  of  precipitation  with  its  seasons  of  highest  temperature,  A  more  critical 
and  thorough  examination  of  the  northeastern  districts  in  their  mutual  relations  at  the  various 
seasons  is  very  desirable. 

The  district  of  the  great  lakes  has  a  general  feature  of  a  character  perhaps  least  to  be  anticipated, 
in  showing  a  general  diminution  of  the  quantity  of  precipitation  in  comparison  with  the  districts  of 
its  vicinity.  That  these  bodies  of  water  should  reduce  the  annual  quantity  of  rain  instead  of  adding 
to  it  may  appear  improbable,  yet,  in  comparing  the  results  exhibited  on  the  chart  for  the  year,  it  is 
demonstrable  that  they  do  so.  Under  the  general  principle  just  mentioned  the  explanation  is  more 
simple  than  might  be  expected,  since  it  is  dependent  on  the  I'elative  capacities  of  the  local  atmo- 
spheres t-o  sustain  moisture,  the  precipitation  being  more  or  less  profuse  accordingly.     If  at  Cin-

cinnati  the  mean  -temperature  may  be  for  some  days  at  85°  and  at  Fovt  Gratiot  at  but  60°,  with  a 
degree  of  humidity  near  saturation  in  both  cases,  a  change  of  temperature  which  would  precipitate 
like  proportions  of  this  moisture  would  give  twice  the  depth  of  rain  at  the  former  place.  Such,  for 
nearly  all  parts  of  the  year,  are  the  relative  thermal  conditions  for  the  atmosphere  of  this  immense 
cool  water  surface  and  that  of  the  Ohio  and  Mississippi  valleys,  and  the  hyetal  conditions  are  only 
similarly  contrasted. 

If  the  q^uantity  of  water  precipitated  at  all  seasons  depended  on  local  sources  of  supply  in  the 
evaporation  from  ocean  or  lake  surfaces,  there  should  be,  notwithstanding  the  rule  just  mentioned,  a 
considerable  increase  on  the  hills  in  the  vicinity  of  the  lakes  in  winter  or  the  colder  seasons.  There  is, 
undoubtedly,  a  partial  or  small  increase  of  this  sort,  which  is  most  conspicuous  in  New  York  and  in 
the  vicinity  of  Lake  Superior.  But  the  amount  so  added  is  due  to  the  greater  temperature  of  the 
lakes  at  this  season,  and  to  their  slower  cooling,  as  their  local  atmosphere  retains  a  degree  of  humidity 
and  a  capacity  for  moisture  which  does  not  belong  to  the  atmosphere  of  the  land  areas  in  their  vicinity. 
The  quantity  is  also  not  very  great,  and  it  is  more  conspicuous  at  the  cold  season,  than  important  in  its 
addition  to  the  quantity  for  the  year.  The  number  of  days  of  rain  and  snow  is  also  increased 
disproportionately  to  the  actual  quantity.  "West  of  Lake  Superior  there  is,  apparently,  a  heavier  fall 
of  snow  in  winter  than  elsewhere,  or  perhaps  this  profusion  belongs  to  all  the  hills  and  low  mountains 
surrounding  this  great  lake,  and  reaching  west  to  the  Red  river  of  the  North.  The  great  plains  begin 
at  this  western  limit,  and  they  stretch  northwestward  to  the  Saskatchewan  and  beyond  it,  the  whole 
country  to  the  Kooky  mountains,  indeed,  being  a  single  low  and  unbroken  plain.  Whatever  influ- 
ence moderate  elevations  would  have  in  this  latitude  and  position  in  inducing  a  heavier  fall  of  rain 
and  snow  might  he  anticipated  here,  and  there  may  be  a  relatively  large  quantity  so  derived.  This 
does  not  affect  the  general  feature  of  the  lake  district  which  has  been  examined,  as  nearly  all  the 
country  in  the  vicinity  of  the  other  lakes  is  a  plain  very  little  elevated  above  the  lakes  themselves. 

There  is  an  exceptional  district,  having  a  great  fall  of  rain,  in  Iowa,  which  requires  some 
explanation,  especially  in  its  contrast  with  the  small  quantities  at  Lake  Michigan.  The  exception 
is  in  part  in  the  fact  that  it  is  cut  off  from  the  like  measure  of  fifty  inches  which  belongs  to  so  much 
of  the  Mississippi  valley,  and  this  is  due,  apparently,  to  the  elevation  of  central  Missouri  in  compari- 
son with  lower  Iowa,  and  to  the  near  approach  of  these  elevations  to  St.  Louis,  in  the  form  of  high 
plains,  which  are  similar  to  all  the  elevated  aemi-plateaux  of  those  States.  In  Illinois  the  configura- 
tion is  somewhat  similar,  or  there  are  extensive  open  plains  ;  but  in  Iowa  and  northern  Missouri  there 
is  a  district  lower  than  these,  which  has  a  high  temperature,  and  which  may  he  designated  as  a  sort  of 
atmospheric  eddy,  similar  to  that  of  the  lower  Mississippi.  In  the  northwest  of  Iowa  the  cGteau  for- 
mation appears  in  its  most  perfect  dcvolopment,  and  there  are  decided  features  of  this  sort  in  central 
Wisconsin.  On  these^  and  on  the  shore  of  Lake  Michigan,  the  quantity  falls  off  abruptly,  in  a 
manner  strikingly  like  the  curvatures  of  the  thermal  lines. 

The  influence  of  the  plains  is  thus  apparently  extended  eastward  at  St.  Louis,  reducing  the  quantity 
elsewhere  belonging  to  the  Mississippi  valley  from  fifty  to  forty-five  inches  in  the  mean  for  the 
year,  though  the  belt  so  reduced  is  comparatively  narrowband  it  does  not  reach  to  the  southern 
line  of  Missouri. 

Another  instance  of  the  intrusion  of  the  influence  of  the  plains  appears  at  Tort  Snelling,  and 
the  principles  are  the  same  as  in  the  case  Just  examined.  The  district  is  more  extensive,  however, 
belonging  to  the  whole  coteau  region  of  the  Mississippi  and  Missouri,  The  reduction  in  quantity  is

very  great,  and  farther  west  tbe  measure  aoon  Mis  off  to  fifteen  inchea,  probalily.  There  are  no 
sufficient  measurements  for  this  district,  however,  and  only  local  descriptions  and  analogies  are 
relied  upon  in  carrying  the  illustration  heyond  the  ohserved  points  at  the  military  posts.  One 
striking  remark  ia  usually  made  of  these  prairie  reaches,  from  Fort  Pierre  to  Fort  Union,  (of  the 
Mieaouri,)  and  for  much  of  the  remaining  distance  to  Fort  Benton,  (hat  ikey  are  uncidtivaUe  from 
the  absence  of  smnmer  rain.  It  is  observed,  in  an  equally  decided  manner,  that  the  winter  rains  and 
snows  are  of  very  small  amount,  and  it  is  clear  that  with  these  large  delicienciea  in  the  extreme 
seasons  the  sum  for  the  year  cannot  be  large.  There  are  some  partial  records  at  Fort  Benton  and 
Fort  Pierre*  which  fully  support  this  view,  and  which  give,  with  estimates  for  some  partially  omitted 
months,  the  measures  used  in  the  illustration. 

Below  this  great  arid  area  of  the  plains  there  is  a  belt  of  more  abundant  raina,  which  stretches 
out  on  the  highlands  of  Missouri  first,  and  which  subsequently  comes  nearer  the  Canadian  river.  Its 
largest  measure  ia  on  the  Wichita  and  other  mountains  of  the  vicinity  of  the  Canadian  river,  and  at 
this  latitude  it  appears  to  approach  nearly  to  the  spurs  of  the  Rocky  mountains,  in  their  extension 
eastward  from  Sante  Fe,  The  positive  measurements  at  Fort  Eiley  and  Fort  Atkinson,  with  those 
at  Fort  Arbuckle,  Laa  Vegaa,  and  Fort  Union,  are  the  only  data  of  this  sort  yet  procured.  But  the 
choice  of  this  district  as  a  route  for  transit  to  New  Mexico,  and  the  general  evidence  afforded  by 
the  rains  there  encountered,  proves  it  to  be  comparatively  well  supplied  with  rains  at  a  time  when 
other  parts  of  the  plaina  are  quite  deficient.  This  is,  however,  only  a  comparative  statement,  and 
one  in  reference  to  other  portions  near  these  meridians.  All  portions  differ  extremely  from  the 
immediate  valley  of  the  Mississippi. 

In  northern  Texas  another  particularly  dry  plain  throws  the  shadings  eastward,  but  south  of 
this  the  rougher  elevations  and  low  mountains  have  a  larger  fall  of  rain,  which  belongs  in  some 
degree  to  the  mountains  farther  up  the  Rio  Gtrande.  The  lower  valley  of  the  Eio  G-rande  is  again 
extremely  dry,  except  just  on  the  coast  of  the  Gulf,  and  southward  from  this  point  it  is  only  known 
that  the  rains  are  much  more  profuse  until  the  high  interior  of  Mexico  is  attained.  The  last  dry 
district  named  is,  therefore,  the  most  southern  point  to  which  this  deficiency  falls  for  districts  having 
the  general  elevation  of  the  United  States. 

As  the  large  measures  of  rain  for  the  eastern  United  States  appear  to  be  so  directly  associated 
with  the  temperature,  the  explanation  of  the  diminution  on  the  immediate  coasts  is  not  difficult.  On 
the  summer  thermal  chart  the  line  of  80°  is  seen  to  follow  the  Grulf  coast  throughout,  while  82°  and  85" 
appear  at  large  areas  of  the  interior.  The  temperature  does  not  rise  so  high  within  reach  of  the  sea 
breezes,  nor  is  the  degree  or  fraction  of  saturation  so  great.  By  those  who  are  familiar  with  the 
climate  of  the  coasts  this  has  long  been  understood,  and  the  removal  of  troops  to  the  most  exposed 
coast  positions,  to  avoid  the  unhealthiness  of  the  high  temperature  and  more  excessive  saturation  of 
partially  interior  posts,  has  been  practiced  for  many  years.  The  rains  are  less  profuse  for  even  slight 
differences  of  this  sort,  and  we  need  look  no  farther  for  the  explanation  of  the  differences  of  the 
records.  On  the  south  Atlantic  coast  this  result  is  perhaps  more  marked  than  elsewhere,  though 
the  record  at  Fort  Marion  is  not  relied  upon  as  entkely  accurate.  But  the  contrast  of  Fort  Moultrie 
and  Oglethorpe  Barracks,  and  that  of  Sea  islands  near  Savannah  with  the  city  itself,  affords  decisive 
comparisons. t     Farther  north  the  exposed  coast  positions  show  a  diminution  evidently  due  to  this

local  cause,  and  the  farther  these  are  at  sea,  or  the  more  fully  exposed  to  such  infliieacea,  the  greater 
is  the  difference  of  measurements  disclosed.  Near  the  Grulf  stream  the  conditions  may  he  reversed, 
however,  as  the  temperature  is  considerahly  greater  there. 

In  Florida  the  illustration  for  the  year  must  he  taken  as  in  some  degree  hypothetical.  At  Key  West 
the  cLuantity  is  certainly  comparatively  small,  though  the  records  there  differ  very  much  from  different 
sources  and  for  different  years.  An  apparently  reliahle  record  by  W.  A,  Whitehead,  esq. ,  gives 
nearly  thirty-two  inches  for  a  mean  of  fourteen  years,  though  some  part  of  this  period  was  taken  from 
other  sources.  The  record  at  the  military  post  differs  largely  from  this,  and  in  part  this  difference  is 
due  to  greater  profusion  of  rains,  yet  the  result  may  not  be  wholly  relied  upon.  A  mean  of  these,  or 
thirty-aisi  inches,  is  thought  to  he  near  the  average  which  an  extended  period  would  give,  and  this  is 
confirmed  by  partial  results  on  other  islands.*  But  in  the  interior  of  the  lower  part  of  the  peninsula 
the  local  rains  are  most  excessive,  and  the  local  humidity  and  high  temperature  sufficiently  extreme 
to  render  the  measurement  of  the  large  q^uantities  there  free  from  doubt.  Posts  on  opposite  coasts 
of  the  peninsula  there  usually  agree  in  the  cases  of  greater  profusion.  The  non-periodic  range 
is,  however,  very  great  for  every  portion  of  Florida,  and  more  complete  periods  are  required  to  give 
reliable  measures. 

The  annual  mean  results,  in  the  districts  of  periodical  rains,  have  less  interest  and  importance  as 
such,  than  in  those  where  the  whole  year  is  similar,  or  is  a  period  of  continued  precipitation.  The 
interest  belongs  to  the  seasons  in  the  first  case,  and  not  so  much,  perhaps,  to  the  recognized  or 
standard  divisions  as  such,  as  to  the  wet  and  dry  seasons  of  these  districts,  whatever  periods  of  time 
they  may  embrace.  There  is  a  great  area  very  deficient  in  atmospheric  precipitation,  which  stretches 
from  the  Rocky  mountains  to  the  great  coast  ranges,  and  from  the  point  where  the  two  ranges  merge 
in  one  in  British  America,  south  to  near  the  latitude  of  the  city  of  Mexico.  Though  both  these  great 
mountain  systems  are  broken  down  in  the  vicinity  of  the  32d  parallel,  they  rise  again  in  Mexico,  the 
coast  range  at  the  east  arresting  the  tropical  rains  from  one  ocean,  and  that  at  the  west  from  the 
other. t  Within  the  limits  of  the  United  Statea  this  great  arid  region  may  be  said  to  embrace  ten 
degrees  of  longitude  and  seventeen  of  latitude,  drained  only  by  the  Columbia  and  Great  Colorado 
rivers  in  any  outlet  to  the  sea,  Eully  half  of  it  is  the  Great  Basin  of  the  interior,  which  does  not 
receive  a  sufficient  quantity  of  rain  to  require  any  external  drainage.  Taking  this  basin  at  nearly 
eight  degrees  of.  latitude  by  seven  of  longitude,  we  have  two  hundi-ed  thousand  square  miles  so 
deficient  in  rain  as  to  send  out  no  rivers,  and  to  accumulate  no  considerable  lakes,  and  this 
statement  places  the  contrast  with  the  eastern  United  States  in  the  clearest  light.  The  two  great 
rivers  of  the  whole  arid  district  receive  most  of  their  volume  from  the  mountains  themselves,  and 
beyond  its  proper  limits,  and  their  basins  might  appropriately  he  added  to  the  calculation,  making 
nearly  foiu"  hundred  thousand  square  miles  of  surface,  which,  of  itself,  would  send  no  rivers  to  the  sea. 
In  the  division  of  river  or  hydrographic  systems  this  deserves  a  distinct  place,  and  its  basis  is  in  the  per- 
manent hyetal  condition,  which  may  or  may  not  here  he  wholly  dependent  on  altitude  and  configuration. 

The  summary  for  the  Pacific  coast  presents  no  features  not  apparent,  in  some  degree,  in  the 
summaries  for  the  seasons.  It  is  to  be  regretted  that  the  period  of  time  is  not  longer  for  the  upper 
part  of  this  coast,  and  that  the  facilities  for  connecting  the  illustration  still  further  northward  are

762  REPORT, 

not  at  hand.  Beyond  Astoria  and  Steilacoom  wo  have  only  two  years  of  observation  at  Sitka,  from 
Eussian  authorities,  with  a  mean  of  79.5  inches  for  the  year.  Without  much  prohability  of  error  we 
may  suppose  the  quantity  at  Astoria  continued,  with  a  less  rapid  increase  than  before  reaching  this 
point,  to  Sitka,  and  the  whole  of  this  immediate  coast  to  be  marked  by  great  profusion.  Richardson 
notices  its  extreme  humidity,  and  considers  its  degree  greater  than  that  of  the  most  humid  coasts  of 
the  British  islands. 

The  periods  of  observation  at  the  older  military  posts  are  suffieient  only  to  open  the  question  of 
permanence  in  regard  to'  the  quantity  of  rain  falling  in  an  extended  series  of  years.  If  this  condition 
is  directly  and  necessarily  associated  with  the  temperature,  the  permanence  of  that  gives  strong  evi- 
dence, at  least,  that  there  is  no  change  in  progress  in  regard  to  the  quantity  of  rain.  It  has  been  seen 
that  no  evidence  of  periodicity  or  of  progressive  movement  in  any  direction  is  apparent  in  the 
temperature  records,  but  as  positive  observation  would  be  decisive  against  any  form  of  inference 
whatever,  a  brief  reference  to  the  annual  summaries  of  the  longer  series  may  be  made. 

The  posts  of  the  New  England  States  show  some  uniformity  previous  to  1850 ;  the  best  series,  at 
Hancock  Barracks,  does  so  particularly.  In  1850  to  1853  the  quantities  are  greater  than  before, 
and  comparison  with  records  from  other  sources,  going  farther  back  than  any  of  these,*  establish 
the  correctness  of  this  increase  for  those  years  ;  the  excess  was  principally  in  southern  New 
England  and  ISew  York.  At  Fort  Columbus  the  most  complete  of  the  northern  series  occurs, 
and  the  excess  here  in  1837  and  ISiV  is  generally  supported  at  other  posts,  and  by  records  from  other 
sources  in  the  vicinity.  That  of  1837  was  observed  at  Fort  Wood,  New  York  harbor,  and  it  has  some 
appearance  of  being  over  measured.  The  complete  mean  of  this  post  agrees  strildngly  with  that  at 
other  points  of  the  vicinity,  including  extensive  periods  at  academies  on  Long  Island.  At  West  Point 
the  greatest  difBculty  or  anomaly  is  presented,  andcomparisonofits  measurements  forthe  earlier  years 
with  those  of  the  Academies  at  Hudson,  Poughkeepsie,  Newburgh,  New  York,  and  Albany ;  with  indeed 
several  other  points  of  the  Hudson  river  valley,  induces  the  opinion  that  local  influences  in  regard  to 
the  position  of  the  gauge,  or  error  in  use  of  the  scale,  render  the  measurements  for  the  years  referred 
to  decidedly  in  excess.  The  quantities  for  1837-8  and  9  are  unprecedented,  and  all  for  first  six  or 
seven  years  are  nearly  twice  as  great  as  the  measurements  at  the  points  above  enumerated.  There  are, 
evidently,  local  causes  of  profiise  precipitation  here  which  do  not  exist  in  this  valley  generally,  and 
this  is  suihciently  clear  from  the  last  twelve  years  of  the  record,  which  bear  a  uniform  relation  to 
other  like  periods.  But  the  great  decrease  in  quantity  from  the  mean  of  the  first  six  years  is  not 
shown  in  any  other  case,  and  it  can  scarcely  be  supposed  that  this  single  locality  is  exceptional  in  this 
respect  in  so  great  a  degree.  The  highlands  of  southern  New  York  and  New  England  at  some  points 
show  as  much  deficiency  as  the  excess  here  admitted,  or  the  difference  of  four  inches  in  the  annual 
mean  from  the  measures  at  other  points  of  the  vicinity. 

At  Watervliet  there  is  evidently  an  under  measurement  of  winter  precipitation,  and  the  locality 
may  have  the  effect  to  still  further  diminish  the  quantity  as  compared  with  Albany.  The  mean  of 
forty  inches  at  this  latter  point  is  no  doubt  entirely  reliable  as  a  representative  of  the  general  district. 
The  uniformity  of  the  results  at  Watervliet  arsenal  for  successive  years  belongs  to  the  records  at 
Albany,  Troy,  and  other  points  of  the  vicinity,  and  no  evidence  of  the  change  occurring  at  West 
Point  exists  in  any  case.

REPORT.  763 

The  series  at  Alleghany  arsenal  is  also  strong  evidence  that  all  the  variations  in  quantity  are  non- 
periodic,  and  similar  to  those  of  temperature.  The  range  appears  to  he  no  greater  here  than  at  New 
York,  and  in  hoth  caeea  it  is  nearly  as  much  as  the  least  quantity  which  has  fallen  in  any  year.  At 
Fort  McHenry,  Baltimore,  a  very  good  series  exists  with  similar  features.  Some  unimportant 
correction  is  supposed  to  belong  to  the  last  two  years,  but  these  do  not  affect  this  position.  At  Fort 
Monroe,  ll^orfolk,  a  large  range  occurs,  and  though  the  range  here  is  probably  greater,  as  shown  by 
the  analogies  of  the  temperature  range,  the  extreme  quantities  are  somewhat  doubtful— 1839  and 
1840  on.  the  one  side,  and  1852  and  1854  on  the  other.  If  their  accuracy  is  confirmed,  as  it  may  be 
by  further  examination,  the  range  is  certainly  very  extraordinary.  As  this  district  of  central 
position  north  and  south  is  still  incomplete  in  regard  to  observation,  separate  summaries  at  this  post 
are  made  for  the  purpose  of  illustrating  the  probable  determinations,  or  those  resulting  in  any  case, 
whether  the  apparently  exceptionable  quantities  are  or  are  not  retained.  It  is  clear  that  the  range 
on  this  slope  of  the  AUeghaniea  is  very  great,  and  that  partial  periods  are  quite  inadequate  to 
determine  the  mean  annual  fall,  It  amounts  to  two  and  a  half  times  the  least  observed  quantity  at 
Fort  Monroe,  if  the  extreme  years  are  not  included. 

Similar  features  of  great  range  belong  to  all  the  central  districts  of  the  United  States,  including 
the  older  posts  west  of  the  Mississippi.  AH  the  districts  having  a  great  mean  annual  quantity  are  so 
characterized,  and  the  range  is  greatest  where  the  thermal  variation  is  greatest.  At  Fort  Leaven- 
worth the  lowest  quantity  is  less  than  one-third  of  the  greatest,  while  at  the  posts  of  the  western  lake 
district  the  range  is  very  much  less. 

The  measurement  of  the  quantity  of  rain  has  inherent  difficulties  not  readily  understood  or 
apparent,  except  in  the  actual  trial,  arising  from  accidental  interruptions  or  defects  of  exposure, 
alterations  in  the  shape  of  the  gauge  by  freezing,  and  in  the  use  of  the  scale,  &c. ;  but  the 
averages  derived  from  long  perio^la  are  seen  to  be  reliable  for  all  general  conclusions,  particularly 
when  the  quantities  for  all  the  posts  of  an  extensive  district  are  placed  together  in  their  natural 
1  relations.

NOTES   AND   ERRATA, 


In  Bome  of  the  Eignaturea  of  the  statistical  poi'tiouB  of  tiiis  volume  errora  of  computation  were  introdiicBil,  wliicli  tha  sulreequent 
roduction  of  the  results  in  the  summSiry  tables  served  to  detect  The  successive  forms  in  which  the  statisfjcs  were  recombined  and 
jussed  each  served  as  a  criticism  on  computations  and  determinations  as  well  he  on  typographical  accuracy.  It  will  be  observed
