THE EXPLOSION
Tom and Ned were so startled by the
entrance of the excited man with his cry of “Fire!”
that the young inventor nearly dropped the tank of
liquid extinguisher he was helping to hoist into the
aeroplane. Then, as he caught sight of his visitor,
Tom exclaimed:
“Hello, Mr. Damon! We were
wondering whether you’d be along to witness
our first experiment.”
“Experiment, Tom Swift!
Experiment! Bless my Latin grammar! but you’d
much better be calling out the fire department to play
on that blaze down in your meadow. What is it—your
barns or one of your new shops?”
“Neither one, Mr. Damon,”
laughed Ned. “It’s only a blaze that
Koku and Rad started.”
“And the fire department is here,” added
Tom.
“Where?” inquired the eccentric man.
“Here,” and Tom pointed
to his airship—one of the smaller craft—into
which the tank of chemicals had been hoisted.
“Oh!” exclaimed Mr. Damon.
“Something new, eh, Tom?” His eyes glistened.
“Yes. Fighting fires from
the air. I got the idea after the fireworks factory
went up in smoke. Will you come along? There’s
plenty of room.”
“I believe I will,” assented
Mr. Damon. It was not the first time, by any
means, that he had gone aloft with Tom. “I
happened to be coming over in my auto,” he went
on to explain, “when I happened to see the fire
down in the meadow. I was afraid you didn’t
know about it.”
“Oh, yes,” replied Tom.
“I had Rad and Koku light a big pile of packing
boxes, to represent, as nearly as possible, on a small
scale, a burning building. I plan now to sail
over it and drop the tins of chemicals. They
are arranged to burst as they fall into the blaze,
and I hope the carbon dioxide set loose will blanket
out the fire.”
“Sounds interesting,”
commented Mr. Damon. “I’ll go along.”
The airship was wheeled out of the
hangar and was soon ready for the flight. A big
cloud of black vapor down in the meadow told Tom and
Ned that Koku and Eradicate had done their work well.
The giant and the colored man had poured oil over the
wood to make a fierce blaze that would give Tom’s
new chemical combination a severe test.
A mechanic turned the propeller of
the airship until there was an accumulation of gas
in the different cylinders. Then he stepped back
while Tom threw on the switch. This was not one
of the self-starting types, of which Tom possessed
one or two.
“Contact!” cried Tom sharply,
and the man stepped forward to give the big blades
a final turn that would start the motor. There
was a muffled roar and then a steady staccato blending
of explosions. Tom raced the motor while his
men held the machine in place, and then, satisfied
that all was well, the young inventor gave the word,
and the craft raced over the ground, to soar aloft
a little later.
Tom, Ned and Mr. Damon could look
down to the meadow where the bonfire was blazing.
A crowd had collected, but the heat of the blaze kept
them at a good distance. Then, as many of the
throng caught sight of the airship overhead, there
was a new interest for them.
Tom had told Ned and Mr. Damon, before
the trio had entered the machine, what he wanted them
to do. This was to toss the chemicals overboard
at the proper time. Of course in his perfected
apparatus Tom hoped to have a device by which he could
drop the fire extinguishing elements by a mere pressure
of his finger or foot, as bombs were released from
aircraft during the war. But this would serve
for the time being.
Nearer and nearer the blaze the airship
approached until it was almost above it. Tom
had had some experience in bomb-dropping, and knew
when to give the signal.
At last the signal came. Mr.
Damon and Ned heaved over the side the metal containers
of the powerful chemicals.
Down they went, unerring as an arrow,
though on a slant, caused by the impetus given them
by the speed of the airship.
Tom and his friends leaned over the
side of the machine to watch the effect. They
could see the chemicals strike the blaze, and it was
evident from the manner in which the fire died down
that the containers had broken, as Tom intended they
should to scatter their contents.
“Hurray!” cried Ned, forgetting
that he could not be heard, for no head telephones
were used on this occasion and the roar of the motor
would drown any human voice. “It’s
working, Tom!”
Truly the effect of the chemicals
was seemingly to cause the fire to go out, but it
was only a momentary dying down. Koku and Rad
had made a fierce, yet comparatively small, conflagration,
and though for a time the gas generated by Tom’s
mixture dampened the blaze, in a few seconds—less
than half a minute—the flames were shooting
higher than ever.
Tom made a gesture of disappointment,
and swung his craft around in a sharp, banking turn.
He had no more chemicals to drop, as he had thought
this supply would be sufficient. However, he
had guessed badly. The fire burned on, doing no
damage, of course, for that had been thought of when
it was started in the meadow.
“Something wrong!” declared
the young inventor, when they were back at the hangar,
climbing out of the machine.
“What was it?” asked Ned.
“Didn’t use the right
kind of chemicals,” Tom answered. “From
the way the flames shot up, you’d think I had
poured oil on the blaze instead of carbon dioxide.”
“Bless my insurance policy,
Tom!” cried Mr. Damon, “but I’d
hate to trust to your apparatus if my house caught.”
“Don’t blame you,”
Tom assented. “But I’ll do the trick
yet! This is only a starter!”
During the next two weeks the young
inventor worked hard in his laboratory, Mr. Swift
sometimes helping him, but more often Koku and Eradicate.
Mr. Baxter had recovered sufficiently to leave the
Swift home. But though the chemist seemed well
physically, his mind appeared to be brooding over
his loss.
“If I could only get my secret
formulae back!” he sighed, as he thanked Tom
for his kindness. “I’m sure Field
and Melling have them. And I believe they got
them the night of the fireworks blaze; the scoundrels!”
“Well, if I can help you, please
let me,” begged Tom. And then he dismissed
the matter from his mind in his anxiety to hit upon
the right chemical mixture for putting out fires from
the air.
One afternoon, at the end of a week
in which he had been busily and steadily engaged on
this work, Tom finally moved away from his laboratory
table with a sigh of relief, and, turning to Eradicate,
who had been helping him, exclaimed:
“Well, I think I have it now!”
“Good lan’ ob massy, I
hopes so!” exclaimed the colored man. “It
sho’ do smell bad enough, Massa Tom, to make
any fire go an’ run an’ drown hisse’f!
Whew-up! It’s turrible stuff!”
“Yes, it isn’t very pleasant,”
Tom agreed, with a smile. “Though I am
getting rather used to it. But when it’s
in a metal tube it won’t smell, and I think
it will put out any fire that ever started. We’ll
give it a test now, Rad. Just take that flask
of red stuff and pour it into this one of yellow.
I’ll go out and light the bonfire, and we’ll
make a small test.”
Leaving Rad to mix some of the chemicals,
a task the colored man had often done before, Tom
went out into the yard near his laboratory to start
a blaze on which his new mixture could be tested.
He had not got far from the laboratory
door when he felt a sudden jar and a rush of air,
and then followed the dull boom of an explosion.
Like an echo came the voice of Eradicate:
“Oh, Massa Tom, I’se blowed
up! It done sploded right in mah face!”
