CHAPTER I

AN APPEAL FOR AID


Tom Swift stepped from the door of the machine shop, where he was at
work making some adjustments to the motor of his airship, and
glanced down the road. He saw a cloud of dust, which effectually
concealed whatever was causing it.

"Some one must be in a hurry this morning," the lad remarked, "Looks
like a motor speeding along. MY! but we certainly do need rain," he
added, as he looked up toward the sky. "It's very dusty. Well, I may
as well get back to work. I'll take the airship out for a flight
this afternoon, if the wind dies down a bit."

The young inventor, for Tom Swift himself had built the airship, as
well as several other crafts for swift locomotion, turned to
re-enter the shop.

Something about the approaching cloud of dust, however, held his
attention. He glanced more intently at it.

"If it's an automobile coming along," he murmured, "it's moving very
slowly, to make so much fuss. And I never saw a motor-cycle that
would kick up as much sand, and not speed along more. It ought to be
here by now. I wonder what it can be?"

The cloud of highway dirt rolled along, making some progress toward
Tom's house and the group of shops and other buildings surrounding
it. But, as the lad had said, the dust did not move at all quickly
in comparison to any of the speedy machines that might be causing
it. And the cloud seemed momentarily to grow thicker and thicker.

"I wonder if it could be a miniature tornado, or a cyclone or
whirlwind?" and Tom spoke aloud, a habit of his when he was
thinking, and had no one to talk to. "Yet it can hardly be that." he
went on. "Guess I'll watch and see what it is."

Nearer and nearer came the dust cloud. Tom peered anxiously ahead, a
puzzled look on his face. A few seconds later there came from the
midst of the obscuring cloud a voice, exclaiming:

"G'lang there now, Boomerang! Keep to' feet a-movin' an' we sho'
will make a record. 'Tain't laik we was a autermobiler, er a
electricity car, but we sho' hab been goin' sence we started. Yo'
sho' done yo'se'f proud t'day, Boomerang, an' I'se gwine t' keep mah
promise an' gib yo' de bestest oats I kin find. Ah reckon Massa Tom
Swift will done say we brought dis yeah message t' him as quick as
anybody could."

Then there followed the sound of hoofbeats on the dusty road, and
the rattle of some many-jointed vehicle, with loose springs and
looser wheels.

"Eradicate Sampson!" exclaimed Tom. "But who would ever think that
the <DW52> man's mule could get up such speed as that cloud of dust
indicates. His mule's feet must be working overtime, but he goes
backward about as often as he moves forward. That accounts for it.
There's lots of dust, but not much motion."

Once more, from the midst of the ball-like cloud of dirt came the
voice of the <DW52> man:

"Now behave yo'se'f, Boomerang. We'm almost dere an' den yo' kin sit
down an' rest if yo' laik. Jest keep it up a little longer, an'
we'll gib Massa Tom his telephone. G'lang now, Boomerang."

The tattoo of hoofbeats was slowing up now, and the cloud of dust
was not so heavy. It was gradually blowing away. Tom Swift walked
down to the fence that separated the house, grounds and shops from
the road. As he got there the sounds of the mule's progress, and the
rattle of the wagon, suddenly ceased.

"G'lang! G'lang! Don't yo' dare t' stop now, when we am most dere!"
cried Eradicate Sampson. "Keep a-movin', Boomerang!"

"It's all right, Eradicate. I'm here," called Tom, and when the last
of the dust had blown away, the lad waved his hand to an aged
<DW52> man, who sat upon the seat of perhaps the most dilapidated
wagon that was ever dignified by such a name. It was held together
with bits of wire, rope and strings, and each of the four wheels
leaned out at a different angle. It was drawn by a big mule, whose
bones seemed protruding through his skin, but that fact evidently
worried him but little, for now the animal was placidly sleeping,
while standing up, his long ears moving slowly to and fro.

"Am dat yo', Massa Tom?" asked Eradicate, ceasing his task of
jerking on the lines, to which operation the mule paid not the least
attention.

"Yes, I'm here, Rad," replied Tom, smiling. "I came out of my shop
to see what all the excitement was about. How did you ever get your
mule to make so much dust?"

"I done promise him an extra helpin' ob oats ef he make good time,"
said the <DW52> man. "An' he done it, too. Did yo' see de dust we
made?"

"I sure did, but you didn't do much else. And you didn't make very
good time. I watched you, and you came along like an ice wagon after
a day's work on the Fourth of July. You were going fast, but moving
slow."

"I'spects we was, Massa Tom," was the <DW52> man's answer. "But
Boomerang done better dan I'spected he would. I done tole him yo'd
be in a hurry t' git yo' telephone, an' he sho' did trot along."

"My telephone?" repeated Tom, wonderingly. "What have you and your
mule Boomerang to do with my telephone? That's up in the house."

"No, it ain't! it's right yeah in mah pocket," chuckled Eradicate,
opening a ragged coat, and reaching for something. "I got yo'
telephone right yeah." he went on. "De agent at de station see me
dribin' ober dis way, an' he done ast he t' deliber it. He said as
how he ain't got no messenger boy now, 'cause de one he done hab
went on a strike fo' five cents mo' a day. So I done took de
telephone," and with that the <DW52> man pulled out a crumpled
yellow envelope.

"Oh, you mean a telegram," said Tom, with a laugh, as he took the
message from the odd <DW52> man.

"Well, maybe it's telegraf, but I done understood de agent t' say
telephone. Anyhow, dere it is. An' I s'pects we'd better git along,
Boomerang."

The mule never moved, though Eradicate yanked on the reins, and used
a splintered whip with energy.

"I said as how we'd better git along, Boomerang," went on the
darkey, raising his voice, "Dinnah am mos' ready, an' I'm goin' t'
giv yo' an extra helpin' ob oats."

The effect of these words seemed magical. The mule suddenly came to
life, and was about to start off.

"I done thought dat would cotch yo', Boomerang," chuckled Eradicate.

"Wait a minute, Rad," called Tom, who was tearing open the envelope
of the telegram. "I might want to send an answer back by you. I
wonder who is wiring me now?"

He read the message slowly, and Eradicate remarked:

"'Taint no kind ob use, Massa Tom, fo' t' send a message back wif
me."

"Why not?" asked the young inventor, looking up from the sheet of
yellow paper.

"'Case as how I done promised Boomerang his airman, an' he won't do
nothin' till he has it. Ef I started him back t' town now he would
jest lay down in de road. I'll take de answer back fo' you dis
arternoon."

"All right, perhaps that will do," assented Tom. "I haven't quite
got the hang of this yet. Drop around this afternoon, Rad," and as
the <DW52> man, who, with his mule Boomerang, did odd jobs around
the village, started off down the highway, in another cloud of dust,
Tom Swift resumed the reading of the message.

"Hum, this is rather queer," he mused, when having read it once, he
began at it again. "It must have cost him something to send all this
over the wire. He could just as well have written it. So he wants my
help, eh? Well, I never heard of him, and he may be all right, but I
had other plans, and I don't know whether I can spare the time to go
to Philadelphia or not. I'll have to think it over. An electric
airship, eh? He's sort of following along the lines of my
inventions. Wants my aid--hum--well, I don't know--"

Tom's musings were suddenly cut short by the approach of an elderly
gentleman, who was walking slowly down the path that led from the
house to the country highway which ran in front of it.

"A telegram, Tom?" asked the newcomer.

"Yes, dad," was the reply. "I was just coming in to ask your advice
about it. Eradicate brought it to me."

"What, with his mule, Boomerang?" and the gentleman seemed much
amused. "How did he ever get up speed enough to deliver a telegram?"

"Oh, Eradicate has some special means he uses on his mule when he's
in a hurry. But listen to this message, dad. It's from a Mr. Hosmer
Fenwick, of Philadelphia. He says:"

"'Tom Swift--Can you come on to Philadelphia at once and aid me in
perfecting my new electric airship? I want to get it ready for a
flight before some government experts who have promised to purchase
several if it works well. I am in trouble, and I can't get it to
rise off the ground. I need help. I have heard about your airship,
and the other inventions you and your father have perfected, and I
am sure you can aid me. I am stuck. Can you hurry to the Quaker
City? I will pay you well. Answer at once!'"

"Well?" remarked Mr. Swift, questioningly, as his son finished
reading the telegram. "What are you going to do about it, Tom?"

"I don't exactly know, dad. I was going to ask your advice. What
would you do? Who is this Mr. Fenwick?"

"Well, he is an inventor of some note, but he has had many failures.
I have not heard of him in some years until now. He is a gentleman
of wealth, and can be relied upon to do just as he says. We are
slightly acquainted. Perhaps it would be well to aid him, if you can
spare the time. Not that you need the money, but inventors should be
mutually helpful. If you feel like going to Philadelphia, and aiding
him in getting his electric airship in shape, you have my
permission."

"I don't know," answered Tom, doubtfully. "I was just getting my
monoplane in shape for a little flight. It was nothing particular,
though. Dad, I think I WILL take a run to Philadelphia, and see if I
can help Mr. Fenwick. I'll wire him that I am coming, to-morrow or
next day."

"Very well," assented Mr. Swift, and then he and his son went into
one of the shops, talking of a new invention which they were about
to patent.

Tom little knew what a strange series of adventures were to follow
his decision to go to the Quaker City, nor the danger involved in
aiding Mr. Fenwick to operate his electric airship.




CHAPTER II

MISS NESTOR'S NEWS


"When do you think you will go to Philadelphia, Tom?" asked Mr.
Swift, a little later, as the aged inventor and his son were looking
over some blueprints which Garret Jackson, an engineer employed by
them, had spread out on a table.

"I don't exactly know," was the answer. "It's quite a little run
from Shopton, because I can't get a through train. But I think I'll
start tomorrow."

"Why do you go by train?" asked Mr. Jackson.

"Why--er--because--" was Tom's rather hesitating reply. "How else
would I go?"

"Your monoplane would be a good deal quicker, and you wouldn't have
to change cars," said the engineer. "That is if you don't want to
take out the big airship. Why don't you go in the monoplane?"

"By Jove! I believe I will!" exclaimed Tom. "I never thought of
that, though it's a wonder I didn't. I'll not take the RED CLOUD, as
she's too hard to handle alone. But the BUTTERFLY will be just the
thing," and Tom looked over to where a new monoplane rested on the
three bicycle wheels which formed part of its landing frame. "I
haven't had it out since I mended the left wing tip," he went on,
"and it will also be a good chance to test my new rudder. I believe
I WILL go to Philadelphia by the BUTTERFLY."

"Well, as long as that's settled, suppose you give us your views on
this new form of storage battery," suggested Mr. Swift, with a fond
glance at his son, for Tom's opinion was considered valuable in
matters electrical, as those of you, who have read the previous
books in this series, well know.

The little group in the machine shop was soon deep in the discussion
of ohms, amperes, volts and currents, and, for a time, Tom almost
forgot the message calling him to Philadelphia.

Taking advantage of the momentary lull in the activities of the
young inventor, I will tell my readers something about him, so that
those who have no previous introduction to him may feel that he is a
friend.

Tom Swift lived with his father, Barton Swift, a widower, in the
village of Shopton, New York. There was also in the household Mrs.
Baggert, the aged housekeeper, who looked after Tom almost like a
mother. Garret Jackson, an engineer and general helper, also lived
with the Swifts.

Eradicate Sampson might also be called a retainer of the family, for
though the aged <DW52> man and his mule Boomerang did odd work
about the village, they were more often employed by Tom and his
father than by any one else. Eradicate was so called because, as he
said, he "eradicated" the dirt. He did whitewashing, made gardens,
and did anything else that was needed. Boomerang was thus named by
his owner, because, as Eradicate said, "yo' nebber know jest what
dat mule am goin' t' do next. He may go forward or he may go
backward, jest laik them Australian boomerangs."

There was another valued friend of the family, Wakefield Damon by
name, to whom the reader will be introduced in due course. And then
there was Mary Nestor, about whom I prefer to let Tom tell you
himself, for he might be jealous if I
