have done
what we did."

But of this the surgeon had his doubts.

In spite of the dangerous character of his wound, Jack made a quick
recovery. He was in excellent condition, and the wound was a clean one,
so, as soon as the walls of the artery had healed, he was able to be
about, though he was weak from loss of blood. However, that was soon
made good, and he and Tom, bidding farewell to their late comrades,
returned to the American lines. They had been obliged to get an
extension of leave--at least Jack had--though Tom could report back on
time, and he spent the interim between that and Jack's return to duty,
serving as instructor to the "huns" of his own camp. They were eager to
learn, and anxious to do things for themselves.

Before long Jack returned, though he was not assigned to duty, and
he and Tom visited Paris and told Nellie, Bessie and Mrs. Gleason the
result of their mission.

"You didn't see Harry, of course?" asked Nellie, negatively, though
really hoping that the answer would be in the affirmative.

"Oh, no, we couldn't make out any individual prisoner," said Tom. "There
was a bunch of 'em--I mean a whole lot--there."

"Poor fellows!" said Mrs. Gleason kindly, "Let us hope that they will
soon be released."

"Tom and I have been trying to hit on some plan to rescue Harry," put in
Jack. "And we'd help any others to get away that we could. But is isn't
going to be easy."

"Oh, I don't see how you can do it!" exclaimed Nellie. "Of course I
would give anything in the world to have Harry back with me, but I must
not ask you to run into needless danger on his account. That would be
too much. Your lives are needed here to beat back the Huns. Harry may
live to see the day of victory, and then all will be well."

"I don't believe in waiting, if anything can be done before that." Tom
spoke grimly. "But, as Jack says, it isn't going to be easy," he went
on. "However, we haven't given up. The only thing is to hit on some plan
that's feasible."

They talked of this, but could arrive at nothing. They were not even
sure--which made it all the harder to bear--that Harry had received the
packages dropped in the prison camp at such risk. The only thing that
could be done was to wait and see if he wrote to his sister or his
former chums. Letters occasionally did come from German prisoners, but
they were rare, and could be depended on neither as to time of delivery
nor as to authenticity of contents.

So it wa
