“Are you all ready, Tom?”
“All ready, Mr. Sharp,”
replied a young man, who was stationed near some complicated
apparatus, while the questioner, a dark man, with a
nervous manner, leaned over a large tank.
“I’m going to turn on
the gas now,” went on the man. “Look
out for yourself. I’m not sure what may
happen.”
“Neither am I, but I’m
ready for it. If it does explode it can’t
do much damage.”
“Oh, I hope it doesn’t
explode. We’ve had so much trouble with
the airship, I trust nothing goes wrong now.”
“Well, turn, on the gas, Mr.
Sharp,” advised Tom Swift. “I’ll
watch the pressure gauge, and, if it goes too high,
I’ll warn you, and you can shut it off.”
The man nodded, and, with a small
wrench in his hand, went to one end of the tank.
The youth, looking anxiously at him, turned his gaze
now and then toward a gauge, somewhat like those on
steam boilers, which gauge was attached to an aluminum,
cigar-shaped affair, about five feet long.
Presently there was a hissing sound
in the small frame building where the two were conducting
an experiment which meant much to them. The hissing
grew louder.
“Be ready to jump,” advised Mr. Sharp.
“I will,” answered the
lad. “But the pressure is going up very
slowly. Maybe you’d better turn on more
gas.”
“I will. Here she goes!
Look out now. You can’t tell what is going
to happen.”
With a sudden hiss, as the powerful
gas, under pressure, passed from the tank, through
the pipes, and into the aluminum container, the hand
on the gauge swept past figure after figure on the
dial.
“Shut it off!” cried Tom
quickly. “It’s coming too fast!
Shut her off!”
The man sprang to obey the command,
and, with nervous fingers, sought to fit the wrench
over the nipple of the controlling valve. Then
his face seemed to turn white with fear.
“I can’t move it!”
Mr. Sharp yelled. “It’s jammed!
I can’t shut off the gas! Run! Look
out! She’ll explode!”
Tom Swift, the young inventor, whose
acquaintance some of you have previously made, gave
one look at the gauge, and seeing that the pressure
was steadily mounting, endeavored to reach, and open,
a stop-cock, that he might relieve the strain.
One trial showed him that the valve there had jammed
too, and catching up a roll of blue prints the lad
made a dash for the door of the shop. He was not
a second behind his companion, and hardly had they
passed out of the structure before there was a loud
explosion which shook the building, and shattered all
the windows in it.
Pieces of wood, bits of metal, and
a cloud of sawdust and shavings flew out of the door
after the man and the youth, and this was followed
by a cloud of yellowish smoke.
“Are you hurt, Tom?” cried
Mr. Sharp, as he swung around to look back at the
place where the hazardous experiment had been conducted.
“Not a bit! How about you?”
“I’m all right. But
it was touch and go! Good thing you had the gauge
on or we’d never have known when to run.
Well, we’ve made another failure of it,”
and the man spoke somewhat bitterly.
“Never mind, Mr. Sharp,”
went on Tom Swift. “I think it will be the
last mistake. I see what the trouble is now; and
know how to remedy it. Come on back, and we’ll
try it again; that is if the tank hasn’t blown
up.”
“No, I guess that’s all
right. It was the aluminum container that went
up, and that’s so light it didn’t do much
damage. But we’d better wait until some
of those fumes escape. They’re not healthy
to breathe.”
The cloud of yellowish smoke was slowly
rolling away, and the man and lad were approaching
the shop, which, in spite of the explosion that had
taken place in it, was still intact, when an aged man,
coming from a handsome house not far off, called out,
“Tom, is anyone hurt?”
“No, dad. We’re all right.”
“What happened?”
“Well, we had another explosion.
We can’t seem to get the right mixture of the
gas, but I think we’ve had the last of our bad
luck. We’re going to try it again.
Up to now the gas has been too strong, the tank too
weak, or else our valve control is bad.”
“Oh dear, Mr. Swift! Do
tell them to be careful!” a woman’s voice
chimed in. “I’m sure something dreadful
will happen! This is about the tenth time something
has blown up around here, and-”
“It’s only the ninth,
Mrs. Baggert,” interrupted Tom, somewhat indignantly.
“Well, goodness me! Isn’t
nine almost as bad as ten? There I was, just
putting my bread in the oven,” went on Mrs. Baggert,
the housekeeper, “and I was so startled that
I dropped it, and now the dough is all over the kitchen
floor. I never saw such a mess.”
“I’m sorry,” answered
the youth, trying not to laugh. “We’ll
see that it doesn’t happen again.”
“Yes; that’s what you
always say,” rejoined the motherly-looking woman,
who looked after the interests of Mr. Swift’s
home.
“Well, we mean it this time,”
retorted the lad. “We see where our mistake
was; don’t we. Mr. Sharp?”
“I think so,” replied the other seriously.
“Come on back, and we’ll
see what damage was done,” proposed Tom.
“Maybe we can rig up another container, mix some
fresh gas, and make the final experiment this afternoon.”
“Now do be careful,” cautioned
Mr. Swift, the aged inventor, once more. “I’m
afraid you two have set too hard a task for yourselves
this time.”
“No we haven’t, dad,”
answered his son. “You’ll see us yet
skimming along above the clouds.”
“Humph! If you go above
the clouds I shan’t be very likely to see you.
But go slowly, now. Don’t blow the place
up again.”
Mr. Swift went into the house, followed
by Mrs. Baggert, who was loudly bewailing the fate
of her bread. Tom and Mr. Sharp started toward
the shop where they had been working. It was one
of several buildings, built for experimental purposes
and patent work by Mr. Swift, near his home.
“It didn’t do so very
much damage,” observed Tom, as he peered in
through a window, void of all the panes of glass.
“We can start right in.”
“Hold on! Wait! Don’t
try it now!” exclaimed Mr. Sharp, who talked
in short, snappy sentences, which, however, said all
he meant. “The fumes of that gas aren’t
good to breathe. Wait, until they have blown away.
It won’t be long. It’s safer.”
He began to cough, choking from the
pungent odor, and Tom felt an unpleasant tickling
sensation in his throat.
“Take a walk around,”
advised Mr. Sharp. “I’ll be looking
over the blue prints. Let’s have ’em.”
Tom handed over the roll he had grabbed
up when he ran from the shop, just before the explosion
took place, and, while his companion spread them out
on his knee, as he sat on an upturned barrel, the lad
walked toward the rear of the large yard. It
was enclosed by a high board fence, with a locked
gate, but Tom, undoing the fastenings, stepped out
into a broad, green meadow at the rear of his father’s
property. As he did so he saw three boys running
toward him.
“Hello!” exclaimed our
hero. “There are Andy Foger, Sam Snedecker
and Pete Bailey. I wonder what they’re
heading this way for?”
On the trio came, increasing their
pace as they caught sight of Tom. Andy Foger,
a red-haired and squint-eyed lad, a sort of town bully,
with a rich and indulgent father, was the first to
reach the young inventor.
“How-how many are killed?” panted Andy.
“Shall we go for doctors?” asked Sam.
“Can we see the place?”
blurted out Pete, and he had to sit down on the grass,
he was so winded.
“Killed? Doctors?”
repeated Tom, clearly much puzzled. “What
are you fellows driving at, anyhow?”
“Wasn’t there a lot of
people killed in the explosion we heard?” demanded
Andy, in eager tones.
“Not a one,” replied Tom.
“There was an explosion!”
exclaimed Pete. “We heard it, and you can’t
fool us!”
“And we saw the smoke,” added Snedecker.
“Yes, there was a small explosion,”
admitted Tom, with a smile, “but no one was
killed; or even hurt. We don’t have such
things happen in our shops.”
“Nobody killed?” repeated
Andy questioningly, and the disappointment was evident
in his tones.
“Nobody hurt?” added Sam,
his crony, and he, too, showed his chagrin.
“All our run for nothing,”
continued Pete, another crony, in disgust.
“What happened?” demanded
the red-haired lad, as if he had a right to know.
“We were walking along the lake road, and we
heard an awful racket. If the police come out
here, you’ll have to tell what it was, Tom Swift.”
He spoke defiantly.
“I’ve no objection to
telling you or the police,” replied Tom.
“There was an explosion. My friend, Mr.
Sharp, the balloonist, and I were conducting an experiment
with a new kind of gas, and it was too strong, that’s
all. An aluminum container blew up, but no particular
damage was done. I hope you’re satisfied.”
“Humph! What you making,
anyhow?” demanded Andy, and again he spoke as
if he had a right to know.
“I don’t know that it’s
any of your business,” Tom came back at him
sharply, “but, as everyone will soon know, I
may as well tell you. We’re building an
airship.”
“An airship?” exclaimed Sam and Pete in
one breath.
“An airship?” queried
Andy, and there was a sneer in his voice. “Well,
I don’t think you can do it, Tom Swift!
You’ll never build an airship; even if you have
a balloonist to help you!”
“I won’t, eh?” and
Tom was a trifle nettled at the sneering manner of
his rival.
“No, you won’t! It
takes a smarter fellow than you are to build an airship
that will sail. I believe I could beat you at
it myself.”
“Oh, you think you could?”
asked Tom, and this time he had mastered his emotions.
He was not going to let Andy Foger make him angry.
“Maybe you can beat me at racing, too?”
he went on. “If you think so, bring out
your Red Streak and I’ll try the Arrow against
her. I beat you twice, and I can do it again!”
This unexpected taunt disconcerted
Andy. It was the truth, for, more than once had
Tom, in his motor-boat, proved more than a match for
the squint-eyed bully and his cronies.
“Go back at him, Andy,”
advised Sam, ire low voice. “Don’t
take any of his guff!”
“I don’t intend to,”
spluttered Andy. “Maybe you did beat me
in the races, because my motor wasn’t working
right,” he conceded, “but you can’t
do it again. Anyhow, that’s got nothing
to do with an airship. I’ll bet you can’t
make one!”
“I don’t bet,” replied
Tom calmly, “but if you wait a few weeks you’ll
see me in an airship, and then, if you want to race
the Red Streak against that, I’ll accommodate
you. Or, if you want to enter into a competition
to build a dirigible balloon or an aeroplane I’m
willing.”
“Huh! Think you’re
smart, don’t you? Just because you helped
save that balloonist from being killed when his balloon
caught fire,” went on Andy, for want of something
better to say. “But you’ll never build
an airship!”
“Of course he won’t!”
added Sam and Pete, bound to side with their crony,
to whom they were indebted for many automobile and
motor-boat rides.
“Just wait,” advised Tom,
with a tantalizing smile. “Meanwhile, if
you want to try the Red Streak against the Arrow,
I’m willing. I have an hour or so to spare.”
“Aw, keep still!” muttered
Andy, much discomfited, for the defeat of his speedy
boat, by a much smaller and less powerful one, was
a sore point with him. “You just wait,
that’s all. I’ll get even with you!”
“Look here!” cried Tom,
suddenly. “You always say that whenever
I get the best of you. I’m sick of hearing
it. I consider that a threat, and I don’t
like it. If you don’t look out, Andy Foger,
you’ll have trouble with me, and at no very
distant date!”
Tom, with flashing eyes, and clenched
fists, took a step forward. Andy shrank back.
“Don’t be afraid of him,”
advised Sam. “We’ll stand by you,
Andy.”
“I ain’t afraid,”
muttered the red-haired lad, but it was noticed that
he shuffled off. ” You just wait, I’ll fix you,”
he added to Tom. The bully was plainly in a rage.
The young inventor was about to reply,
and, possibly would have made a more substantial rejoinder
to Andy than mere words, when the gate opened, and
Mr. Sharp stepped out.
“The fumes have all cleared
away, Tom,” he said. “We can go in
the shop, now.”
Without further notice of Andy Foger,
Tom Swift turned aside, and followed the aeronaut
into the enclosed yard.
