his old roommate.
"I'll tell you pretty soon; everybody is safe and all O.K.," answered
Ted. And then he beheld the blood dripping from Jack's wounded arm.

"Wait a moment; what's wrong here?" he exclaimed, lifting the arm
tenderly and disclosing to the view of the excited group of Americans
a wound just above the wrist.

"Oh, it's just a scratch on the arm; one of the Boches nipped me while
I was out there on the U-boat deck waiting for you fellows to come
down through the village," he replied lightly, trying to minimize his
injury.

A first-aid kit was produced and the wound hurriedly dressed. It
seemed to be but a slight flesh wound. In the midst of the dressing
a great shrapnel shell burst just on the other side of the canal
and threw some of its fragments into the water just beyond the U-boat.
At the same moment was heard the whirr of an airplane motor overhead
and very shortly a hand bomb crashed to earth not more than two
hundred yards up the canal towpath, exploding with a terrible detonation
and tearing up a fearful hole in the ground.

"The German guns are all in action now," said Ted as he watched the
airplane circling above the U-boat base.

Jack was soon told of the situation. He had been rescued by a landing
party from several warships of the U.S. fleet. Under the cover of

further up the coast, and another Hun fort further down the coast, the
bluejackets and marines had come ashore.

Seaward could be heard the incessant pounding of the American guns,
intermingled with the boom-boom of the German artillery in the coast
defenses. The German air patrol had flashed warning of the approaching
American fleet and given the range to their gunners.

As Ted finished dressing the flesh wound, Jack saw coming toward him
a naval officer whose epaulets showed him to be a Lieutenant-Commander
of the United States Navy. Jack saluted formally.

"Are you Mr. Jack Hammond of the U.S.S. _Dewey_?" the officer asked.

Jack replied in the affirmative.

"I am Lieutenant-commander Davis of the U.S.S. _Tallahassee_," replied
the officer. "You are the man we came after, and now that we have found
you we must get right out of here as quickly as possible. I should like,
however, to congratulate you on your remarkable exploit in getting away
from the submarine and signaling so fearlessly for aid. Furthermore,
I congratulate you, too, on capturi
