A SUCCESSFUL TEST
“It took you long enough,”
Ned remarked as Tom entered the main office of the
plant, having been to see Mary off on her trip to
Newmarket. This was following his call of the
night before to learn more particulars of her unexpected
visit.
“Yes, I didn’t plan to
be gone so long,” apologized Tom. “But
I thought while I was there I might as well go all
the way with her.”
“And did you?”
“Yes. In the electric runabout.
I wanted to come back and get the airship, but she
said she wanted to look nice when she met her relatives,
and as yet airship travel is a bit mussy. Though
when I get my cabined cruiser of the clouds I’ll
guarantee not to ruffle a curl of the daintiest girl!”
“Getting poetical in your old
age!” laughed Ned. “Well, here is
that statement you said you wanted me to get ready.
Want to go over it now?”
“No, I guess not, as long as
you know it’s all right. I’m going
to start right in and get ready for a bang-up test.”
“Of what—your new aerial fire fighting
apparatus?”
“Yes. Mr. Baxter and I
are going to make up a lot of the chemical compound
that—we discovered through using it on the
blazing tree—will best do the trick.
Then I’m going to try it on a pit fire, and
after that on a big blaze with an airship.”
“Let me know when you do,”
begged Ned. “I want to see you do it.”
“I’ll send you word,” promised the
young inventor.
Then he began several days and nights
of hard work. And he was glad to have the chance
to occupy himself, for, though Tom professed not to
be much affected by the departure of Mary Nestor,
he really was very lonesome.
“How is her uncle, Barton Keith,
by the way?” asked Ned, when he called on his
chum one day, to find him reading a letter which needed
but half an eye to tell was from Mary.
“About as usual,” was
the answer. “He sends word by Mary that
he’ll be glad to see us any time we want to call.
He has some nice offices in the Landmark Building.”
“Those papers proving his right
to the oil land, which you recovered from the sunken
ship for him, must have made his fortune.”
“Well, yes—that and
other things,” agreed Tom. “Say, we
had some exciting times on that undersea search, didn’t
we?”
“Did you call on Mr. Keith when
you went to Newmarket with Mary?” Ned wanted
to know, for he and Tom had taken quite a liking to
Miss Nestor’s uncle.
“No, I didn’t get a chance.
Besides, I wanted to keep away from the Landmark Building.”
“Why?”
“Oh, I might run into Field
and Melling, and I don’t want to see them until
I can accuse them, and prove it, of having taken Mr.
Baxter’s dye formulae.”
“Oh, yes, they’re in the
same building with Mr. Keith, aren’t they?
Why do they call it the Landmark? Though I suppose
the answer is obvious.”
“Yes,” assented Tom.
“It’s a big building—the tallest
ever erected in that city, and a fine structure.
Though while they were about it I don’t see
why they didn’t make it fireproof.”
“Didn’t they?” asked
Ned, in surprise. “Then the insurance rates
must be unusually high, for the companies are beginning
to realize how fire departments, even in big cities,
are hampered in fighting blazes above the tenth or
twelfth stories.”
“Yes, it was a mistake not to
have the Land mark Building fireproof,” admitted
Tom. “And Mr. Keith says the owners are
beginning to realize that now. It is what is called
the ’slow burning’ construction.”
“Insurance companies don’t
go much on that,” declared Ned, who was in a
position to know. “Well, let us hope it
never catches fire.”
These were busy days for the young
inventor. He laid aside all his other activities
in order to perfect the plans for manufacturing his
new chemical fire extinguisher on a large scale.
For Tom realized that while a small quantity of chemicals
in a compound might act in a certain way on one occasion,
if the bulk should happen to be increased the experimenter
could not always count on invariably the same results.
There appeared to be at times a change
engendered when a large quantity of chemicals were
mixed which was not manifest in a small and experimental
batch.
So Tom wanted to mix up a big tank
of his new chemical compound and see if it would work
in large quantities as well as it did with the small
amount Ned had dropped on the blazing tree.
To this end Tom worked at night, as
well as by day, and finally he announced to Ned and
Mr. Damon, who called one evening, that he believed
he had everything in readiness for an exhaustive test
the next day.
“There’s the stuff!”
exclaimed Tom, not a little proudly, as he waved his
hand toward an immense carboy in the main shop.
“That’s what I hope will do the trick.
Just take a—”
“Hold on! Stop! That’s
enough! Bless my hair brush!” cried Mr.
Damon, holding up a protesting hand. “If
you take that cork out, Tom Swift, you and I will
cease to be friends!”
“I wasn’t going to open
it,” laughed the young inventor. “It
has a worse odor and seems to choke you more in a big
quantity than when there’s only a little.
I was just going to shake the carboy to let you realize
how full it was.”
“We’ll take your word
for it!” laughed Ned. “Now about your
test. How are you going to work it?”
“There are to be two tests,”
answered Tom. “The first, and the smaller,
will be in the pit, as before, only this time we shall
have what, I believe, will be the successful combination
of chemicals to drop on it.
“The second test will be the
main one. In that I plan to have an old barn
which I have bought set ablaze. Then Ned and I
will sail over it in the airship and drop chemicals
on it. The barn will be filled with empty boxes
and barrels, to make as hot a fire as possible.
You are invited to accompany us, Mr. Damon.”
“Will there be any smell?”
asked the eccentric man, who seemed to have a dislike
for anything that was not as agreeable as perfume.
“No, the chemicals will be sealed
in containers, which will be dropped from my airship
as bombs were dropped in the war,” said Tom.
“On those conditions I’ll
go along,” agreed Mr. Damon. “But
bless my wedding certificate, Tom! don’t tell
my wife. She thinks I’m crazy enough now,
associating with you and flying occasionally.
If she thought I would help you battle with flames
from the air she’d likely never speak to me again.”
“I’ll not tell,” promised Tom, laughing.
Preparations for the test went on
rapidly. In the morning a fire was to be started
in the same pit where the experiment had partly failed
before.
From the platform over the blazing
hole some of the new combination of chemicals was
to be dropped. If it acted with success, as Tom
believed it would, he proposed to go on with the more
important test in the afternoon.
To this end he had purchased from
a farmer the right to set on fire an old ramshackle
barn, standing in the midst of a field about three
miles outside of Shopton. The barn was on an untilled
farm, the house having been destroyed some years before,
and it was not near any other structures, so that,
even in a high wind, no damage would result.
Tom had filled the barn with inflammable
material, and was going to spare no effort to have
the test as exhaustive as possible.
The time came for the preliminary
trial, and there were a few anxious moments after
the oil-soaked boards and boxes in the pit were set
ablaze.
“Let her go!” cried Tom
to his man on the elevated platform, and down fell
the container of chemicals. It had no sooner struck
and burst, letting loose a mass of flame-choking vapor,
than the fire died out.
“You’ve struck it, Tom!
You’ve struck it!” cried Ned.
“It begins to look so,”
agreed the young inventor. “But I’ll
not call myself out of the woods until this afternoon.
Though we can consider it a success so far.”
Quite a throng was on hand when the
old barn was set ablaze. Tom and Ned and Mr.
Damon were there with the airship which had been especially
fitted to carry the bombs filled with the extinguisher.
In order to insure a quick, hot blaze
the barn was fired on all four sides at once by Tom’s
men. When it was seen to be a veritable raging
furnace of fire, Tom and his two friends took their
places in the airship and rapidly mounted upward.
Necessarily they had to circle off
away from the blaze to get to the necessary height,
but Tom soon brought the airship around again and
headed for the black pall of smoke which marked the
place of the blazing barn.
“We’ll all three send
down bombs at the same time,” Tom told his friends,
as they darted forward. “When I give the
word press the levers, and the chemical containers
will drop. Then we’ll hope for the best.”
Higher mounted the flames, and more
fiercely raged the fire. The heat of it penetrated
even aloft, where Tom and his friends were scudding
along in the airship.
“Now!” cried Tom, as his
craft hovered for an instant in a favorable position
for dropping the bombs. The young inventor, Mr.
Damon, and Ned Newton pressed the levers. Looking
over the sides of the craft, they saw three dark objects
dropping into the midst of the burning barn.
