a thousand feet above
the sea at most, and going very slowly now.
A short time elapsed. Then Beverly completed his task. The flight
lieutenant looked more serious than ever, which told the story even
before he uttered a single word.
Apparently the worst had come, and they were up against a question on the
answer to which everything, even life itself, depended.
"I'm sorry to say it's a positive fact, boys!" called out Beverly, and
as both the others were straining their ears to catch what he said, they
had no difficulty in hearing every word.
"It's the supply pipe clogging then?" Tom asked.
"Yes," came the quick answer. "And while under some conditions I've been
able to get along for a short time without dropping down, as a rule I've
found it wise to look for a landing-place before things got to the point
of desperation and avoid a fall, possibly in the midst of a German
battalion."
"No chance of our getting at it while afloat, is there?" Jack asked,
although he knew what Beverly was bound to say.
"Not the slightest," the other shot back. "It might keep going for
something like an hour, and then shut off the gas entirely. Of course
there's always a possibility of a miracle happening, such as the

our fate?" demanded Jack. "What are you thinking about, Tom, for I can

Tom's face was still colorless, but there was a gleam in his eye, which
Jack had discovered. Perhaps after all it might be only the light of
desperation, a determination to die game if a cruel fortune decreed that
their time had come. Jack could not tell.
"Yes, I have a plan," said Tom quickly. "Perhaps you'll both call it a
wild idea, and think I'm crazy; but desperate cases call for equally
desperate remedies, and at the worst we'll have a chance."
"Good boy, Tom!" cried Jack. "Just like you to hit on a plan! Haven't
I known you to come to the front many times when things looked very
black for us?"
"Tom, tell your scheme!" demanded Beverly. "Things may develop faster
than we suspect now, and if there's any way to get around this trouble
the sooner we start the better."
"Of course," Tom replied, "we'll be taking the risk of smashing the
