teps upon the stairs and a moment later a figure in the full
uniform of a German battleship commander stood before them.

"What's the meaning of this?" he demanded in a harsh voice.

He glanced at the two quickly, and then realizing that he apparently was
talking to a German naval officer, and his subordinate, he addressed
Jack.

"You know his Imperial Majesty's orders in regard to fighting with
civilians?" he asked.

Jack could do nothing but bow.

"Then," said the commander, "I shall have to place you under arrest!"

CHAPTER XXV.

DOOMED TO DIE.

It was a bitter disappointment to Jack, but he felt he could do nothing
but submit. True, he thought to himself, he could probably have attacked
the German commander, and perhaps have overcome him; but there was Frank
to be considered, and his own injured right arm. No, he felt he could do
nothing but submit.

"Very well, sir," he answered the German, "but first you will please
permit me to see to my friend."

He indicated Frank's prostrate form across the room. The German saw it

He drew his revolver and mounted guard over Davis.

"There is really no use my guarding you," he said. "Half a dozen of my
men are below, so you could hardly escape."

In the meantime Jack bent over Frank and raised his chum's head to his
knee. Then he arose, asked permission of the German to leave the room
for water. The permission was granted and Jack returned a moment later,
his cap filled with water.

He sprinkled the water over Frank's face and soon perceived signs of
returning consciousness. Frank drew a deep breath and opened his eyes.
Then he pushed Jack aside and sat up.

"What's happened?" he asked in a faint voice.

In a few words Jack explained.

"I remember now," said Frank. "Help me up."

Jack did so and then for the first time Frank caught sight of the German
naval commander.

"What's he doing here?" he asked of Jack.

"Oh, he's just arrested us; that's all," said Jack.

"Yes," said the German, "and I must ask you to accompany me now. You
shall come aboard my ship until this matter has been investigated
thoroughly. I'll take charge of you, rather than to turn you over to the
military authorities; for after all you are naval officers and I shall
help you if I
