moment before, Hun gums had
been belching at him.

"Good! A sure hit!" cried Tom, but he alone heard his own words. Jack's
ears were filled with the throb of the motor. He had two more bombs,
and these were quickly dropped at different points on German territory
outside the camp.

At the time, aside from the evidences they saw, Jack and Tom were
not aware of the damage they inflicted, but later they learned it was
considerable and effective. However, they guessed that they had created
enough of a diversion to try now to deliver the packages containing the
letters and other comforts.

Jack swung the machine at a sharp angle over the prison camp, and as
he cleared the barbed wire fence Tom, who had been given charge of the
packets, let one go. It fell just outside the barrier, caused by some
freak of the wind perhaps, and the lad could not keep back a sigh of
dismay. One of the three precious packages had fallen short of the mark,
and would doubtless be picked up by some German guard.

But Tom had the satisfaction of seeing the two other bundles fall
fairly within the prison fence, and there was a rush on the part of the
unfortunate men to pick them up.

"I only hope Harry's there," mused Tom. "That's tough luck to wish a
man, I know," he reflected, "but I mean I hope he gets the letters and
things."

However, he and Jack had done all that lay in their power to make this
possible, and it was now time to get back to their own lines if they
could. The place was getting too dangerous for them.

Swinging about in a big circle, and noting that groups of prisoners were
now gathered about the place where the packets had fallen, Jack sent
the machine toward that part of France where they had spent so many
strenuous days.

"They're going to make it lively for us!" cried Jack, as he noted two
swift German planes mounting into the air. "It's going to be a fight."

But he and Tom were ready for this. Their Lewis and Vickers guns were in
position, and they only awaited the approach of the nearest Hun plane to
unlimber them. They mounted steadily upward to get beyond the range of
the anti-aircraft batteries and were soon in comparative safety, since
the Huns, at this particular sector at least, were notoriously bad
marksmen.

With the German planes, that would be a different story, and Tom and
Jack soon found this out to their cost.

For one of the Boche machines came on speedily, and much more quickly
than the boys had
