HELD BACK.
“Hush! Don’t make a sound yet!” was what Frank whispered.
“But look at them, Frank! The skunks are stealing our neat little
trick! They mean to fly away in her!” answered Andy. And perhaps his
husky voice might have been heard only that just then Jules happened
to have started the engine, and the noise of its throbbing pulsations
drowned all other sounds.
Evidently the skilled aviator was bent on making sure that everything
was correct before starting aloft. It was dangerous business under even
the best of conditions; and certainly when they were about to risk
their lives in a craft made by a couple of green-horn lads.
Still, Jules was voicing his surprise and gratification. He had
certainly never expected to find a machine so nearly perfect as the
result of inexperienced lads.
“Marvelous! superb! excellent!” he was saying with his French
extravagance of speech. “I take off my cap to zese boys. Zey are
surely bound to make zare mark in ze profession. Jean, it ees no longer
a chance we take. It ees a certainty. We sall laugh at ze gendarmes
as we soar over zere heads in ze sky. Pouf! a turn of ze hand, and ze
propeller it will buzz. Zen we are off wiz a rush. Get aboard, Jean!”
The taller man did not seem to have quite so much confidence as Jules.
Doubtless he feared that they would be accepting unusual risks in thus
trusting their lives and fortunes to a contraption made by mere boys.
Still, the situation was such that he had to yield to the opinion of
his comrade. And if all went well, it was an ideal method of giving
their enemies the slip.
So, after giving a last look around him, with somewhat of a sigh he
started to attach himself in the position which Jules had pointed out.
The new monoplane had been built especially for two. Frank and his
cousin had that in mind when starting in to construct the machine;
since neither of them wished to cruise through the air alone.
Hence, there was a place for the second man, where he would just
balance matters nicely. And Jules had himself marked out where the two
heavy suit-cases should be tied fast. In this, his former experience
stood him well, since he was aware of all the little tricks developed
by gliding aeroplanes when at work.
“You stay inside here, and when you hear me shout just whoop it up at
the top of your voice. I’m going out to see if I can play a trick on
them, and prevent an ascent,” whispered Frank.
Immediately he was gone, and Andy, feeling mighty shaky, as he
afterwards frankly confessed, succeeded in crawling out from under the
work bench. Still clutching his wrench weapon he tiptoed over to the
vicinity of the open doors, where he stood almost holding his breath in
his desire to have a full supply in his lungs when the signal came to
let loose.
Frank had meanwhile crept softly outside. The shadow cast by the hangar
served to hide him more or less. And besides, both men seemed to be
completely taken up with what they were doing, for they certainly
failed to look his way.
It was apparent that Frank had conceived some sort of idea. These
things often came to him like a flash of light. It was fortunate in the
present instance, for time was of considerable value. At any moment
now, Jules, finding that his companion had settled himself, was apt to
switch the power on to the shaft, and start the propeller to whirling
around.
When that occurred it would be too late for any one to think of
stopping the monoplane, which must begin to move off on its wheeled
base, increasing in momentum with each yard of progress, until finally
it would take gradually to the air, if all went well, in a graceful
upward curve.
Frank had picked up the padlock belonging to the doors, and which was
hanging, open, on a convenient nail. He knew that just outside there
was a long and stout chain, which had been used somehow with the lumber
brought from the yard, and forgotten when the wagon pulled out.
It was in connection with that same chain that his thoughts ran just
now. And he had faith to believe that, if given just half a minute
of time, he could fix it so that the bold thieves would find some
difficulty in breaking away from old Mother Earth when Jules chose to
set that propeller whizzing.
Again was Frank indebted to the noise of the churning engine, for it
effectually deadened what clanking sounds the chain made when he took
hold of its ends, and crept forward.
He kept as low down as he could. Even the moon seemed to be in full
sympathy with the boy’s mission. She had very conveniently hidden
her smiling disc behind quite a dark cloud just then, and brought a
shadow across the face of the land. Perhaps Jules had noticed this
fact. Perhaps he was waiting until it grew light again, so he could
see what lay ahead of them. This ascending from an unknown field must
have all sorts of dangers attached to it, which an experienced aviator
understood.
And so Frank was allowed to reach the rear of the aeroplane without
being detected. His perfect knowledge concerning the build of the
machine served him well at this crisis, for he knew just where to go in
order to find what he sought.
Fortune favored him to a most remarkable degree. Why, if he had the
ordering of the whole affair he could hardly have improved upon the
arrangements. They had pushed the aeroplane out possibly a score of
feet beyond the doors of the hangar. And in so doing the wheels just
avoided a weighty object which Frank had had dumped there, intending
to use the same as an anchor, to which the monoplane could be fastened
when they came to trying her propeller at full speed.
This was a large iron post, that must have weighed all of three hundred
pounds. It had a large ring attached. Once upon a time it stood in
front of the Whympers domicile, and horses were tied to the ring; but
lately it had come to be a nuisance, so that the colonel had ordered
it uprooted, and taken to the dump in the rear, from which the young
aviators had rescued it.
And through that same ring Frank now slipped his chain. His purpose was
plain. Instead of keeping restive horses from taking to their heels,
the old post was now intended to act as a restraining power to a steed
of the upper air currents, and curb the ambition of the monoplane when
the propeller started to turning.
When Frank had managed to pass his chain through the frame of the
rudder he brought the two ends together, and snapped the padlock shut.
Its jaws held the ends of the chain fast, forming an effectual brake.
Satisfied that he had managed to anchor the aeroplane to the ground,
the boy next crept back toward the shed. He knew that the explosion
must come in a brief time now, and wished to be as far away from the
two robbers at that critical moment as possible.
Andy saw some one creeping toward him. The moon was still behind
the cloud, although just about to appear again, having given Frank
all the time he needed. At first Andy thought it must be one of the
robbers coming back to finish him, or else get something that had been
forgotten. And he had even mechanically half raised the big monkey
wrench before he caught a low sign that told him the truth.
What Frank had done he could not even guess; but he had faith in the
other, no matter what the circumstances might be, and believed now that
in some way his chum must have managed to block the game of grab.
“Did you fix it?” he whispered, as the other joined him.
“Watch and see what happens,” came the low reply. “And when I let go,
shout like a house afire. If there’s a policeman inside of half a mile
he’ll come here on the tear.”
The face of the moon began to appear beyond the dark curtain. That was
to be the signal for the start. Jules was bending over even now.
“Hold tight, Jean! It ees to go!” they heard him say, in a thrilling
tone.
“I am ready. Let loose!” answered the other, recklessly, as he clung to
the upright, close to which he had taken his position.
Andy held his breath. Both boys were staring hard at their beloved
monoplane, seen there in the moonlight. How brave she looked; and to
think that two rascally law-breakers were occupying the seats they had
fondly hoped should be their portion when the maiden flight was taken.
The engine still worked steadily, with a series of little explosions
that denoted an expenditure of only a part of its capacity. Suddenly
the propeller commenced to turn swiftly around. Jules had made the
shift!
The monoplane began to move forward on its padded bicycle wheels; and
Andy could not repress a cry of chagrin, as he saw his darling machine
start off.
But his outburst was as nothing compared to the startled exclamations
and angry shouts that arose from the two occupants of the monoplane,
when, after going a dozen feet, it suddenly brought up with a round
turn that almost sent them backwards from their seats.
And with propeller whizzing aimlessly, and engine working steadily,
the trapped aeroplane refused to budge another foot, being held fast by
the lumber chain, and the ground anchor that had once been a massive
hitching post!
