e sure to pick up the signals and that the plant would
be run down. But they have those poles made in sections--they could hide
the whole thing. It takes very little time to set them up. This is simply a
bigger copy of what they use in the field. We've got to get out!"

He looked at his watch.

"Carefully, now," he said. "We've just about got time. That sentry must be
just about passing the place where we got over the wall now. By the time we
get there he'll be gone, and we can slip out. We've got everything we came
for, now that we've seen that!"

They started on the return journey through the woods. More than ever there
seemed to be danger about them. And suddenly it reached out and gripped
them--gripped Harry, at least. As he took a step his foot sank through the
ground, as it seemed. The next moment he had all he could do to suppress a
cry of agony as a trap closed about his ankle, wrenching it, and throwing
him down.

"Go on!" he said to Dick, suppressing his pain by a great effort.

"I won't leave you!" said Dick. "I--"

"Obey orders! Don't you see you've got to go? You've got to tell them about
the wireless--and about where I am! Or else how am I to get away? Perhaps
if you come back quickly with help they won't find me until you come!
Hurry--hurry!"

Dick understood. And, with a groan, he obeyed orders, and went.

CHAPTER VII

A CLOSE SHAVE

Probably Dick did not realize that he was really showing a high order of
courage in going while Harry remained behind, caught in that cruel trap and
practically in the hands of enemies who were most unlikely to treat him
well. In fact, as he made his way toward the wall, Dick was reproaching
himself bitterly.

"I ought to stay!" he kept on saying to himself over and over again. "I
ought not to leave him so! He made me go so that I would be safe!"

There had been no time to argue, or Harry might have been able to make him
understand that it was at least as dangerous to go as to stay--perhaps even
more dangerous. Dick did not think that there was at least a chance that
every trap was wired, so that springing it would sound an alarm in some
central spot. If that were so, as Harry had fully understood, escape for
Dick would be most difficult and probably he too would be captured.

"I'm such a coward!" Dick almost sobbed to himself, for he was frightened,
though, it must be said, less on his account than at the thought of Harry.

Yet he did not stop. He we
