"Hurry!" he cried, and the men increased their stroke.

Near the wreckage Jack gave the command to cease rowing. A German swam
toward the boat. Hands helped him in and he lay in the bottom panting.
Other forms swam toward them. These, too, were lifted in the boat. And
at last Jack counted fifteen Germans who had been saved.

"Are you all here?" he asked of a German officer.

"All but Commander Butz, sir," was the man's reply.

Jack commanded his men to row closer to the wreckage.

"Ahoy there!" he shouted, when he had come close.

The lad thought he heard a muffled answer, but he could not make sure.
He called again. This time the answer came plainer.

"Where are you?" asked Jack.

"Under the wreckage," was the reply.

Jack scrutinized the wreckage closely.

"Looks like it might sink any minute," he said "But we can't leave him
there."

"What are you going to do?" asked Frank.
