The Best Mechanical Paper in the World ! 
A year’s numbers contain over 90 pages and several hundred engravings 


of new machines, useful and novel inventicns, facturing estabi 
ments, tools, and processes. 

The SCIENTIFIC AMERICAN is devoted to the interests of Popular 
Science, the Mechanic Arts, Manufactures, Inventions, Agriculture, Com- 
merce, and the Industrial pursuits generally, and is valuable end instructive 
not only in the Workshop and Manufactory, but also in the Household, the 
Library, and the Reading Room. 


To the Mechanic and Manufacturer /

doing without the SckENTIFIC AMERICAN. Every number contains from six 
to ten engravings of new machines and inventions which cannot be found 
in any other publication. 
Chemists, Architects, Milltorights and Farmers. 

The SCIENTIFIC AMERICAN will be found a most useful journa! to 
them. All the new discoveries in the science of chemistry ate givén 1c 1's 
columns; and the interests of the architect and carpenter are not over- 
looked, all the new inventions and discoveries appertaining to these pur- 
suits being published from week to week. Useful and practical information 
pertaining to the interests of millwrights and millowners wil! be found pub- 
ished in the ScrENTIFIC AMERICAN, which information they cannot possibly 
obtain from any other source. Subjects in which planters and farmers are 
interested will be found discussed in the SCIENTIFIC AMERICAN, many im- 
provements in agricultural implements being illustrated in its col 

We are also receiving, every week, the best scientific journals of Great 
Britain, France and Germany; thus placing in our possession all that is 
transpiring in mechanical scieace and art in these old countries. We shall 
continue to transfer to our columns copious extracts, from these journals, 
of whatever we may deem of interest to our readers.

SCIENTIFIC AMERICAN. 
The Best Mechanical Paper in the World ! 
A year’s numbers contain over 90 pages and several hundred engravings 


of new machines, useful and novel inventicns, facturing estabi 
ments, tools, and processes. 

The SCIENTIFIC AMERICAN is devoted to the interests of Popular 
Science, the Mechanic Arts, Manufactures, Inventions, Agriculture, Com- 
merce, and the Industrial pursuits generally, and is valuable end instructive 
not only in the Workshop and Manufactory, but also in the Household, the 
Library, and the Reading Room. 


To the Mechanic and Manufacturer / 


No person engaged in any of the mechanical pursuits should think of 
doing without the SckENTIFIC AMERICAN. Every number contains from six 
to ten engravings of new machines and inventions which cannot be found 
in any other publication. 
Chemists, Architects, Milltorights and Farmers. 

The SCIENTIFIC AMERICAN will be found a most useful journa! to 
them. All the new discoveries in the science of chemistry ate givén 1c 1's 
columns; and the interests of the architect and carpenter are not over- 
looked, all the new inventions and discoveries appertaining to these pur- 
suits being published from week to week. Useful and practical information 
pertaining to the interests of millwrights and millowners wil! be found pub- 
ished in the ScrENTIFIC AMERICAN, which information they cannot possibly 
obtain from any other source. Subjects in which planters and farmers are 
interested will be found discussed in the SCIENTIFIC AMERICAN, many im- 
provements in agricultural implements being illustrated in its col 

We are also receiving, every week, the best scientific journals of Great 
Britain, France and Germany; thus placing in our possession all that is 
transpiring in mechanical scieace and art in these old countries. We shall 
continue to transfer to our columns copious extracts, from these journals, 
of whatever we may deem of interest to our readers.
