the German sailors
to do but obey. Up went their hands. Von Ludwig called to Harris.

"Help me keep them covered," he said, "while you other two tie them
up."

Under the muzzles of the revolvers levelled in steady hands by von
Ludwig and Harris, Jack and Frank set to work binding the members of
the crew. A few minutes later the work was done.

"Trundle them into that cabin there," said von Ludwig, motioning to an
open door. "Tie them there so they cannot release their own bonds or
the bonds of the others. Then report to me on deck."

The lads obeyed. It was the work of only a few moments, struggle as the
Germans did. Then Frank and Jack went on deck.

A short distance away a rowboat was coming rapidly toward the
_Bismarck_--for such was the name of the vessel on which the lads found
themselves.

Von Ludwig pointed to it.

"My crew!" he said quietly.

CHAPTER XXVI

DISCOVERED

A few moments later the little skiff scraped alongside the _Bismarck_.
One at a time its occupants--five in number--scrambled over the side
and stood before von Ludwig. The latter scrutinized each man closely.

"All right," he said at length.

He selected three men.

"You report to the engine room immediately," he said. "You will find
everything ready. The crew has been overpowered and there will be no

The men moved away. Von Ludwig addressed the other two.

"Take the lookout forward," he said to one; and to the other: "Go aft
and keep your eyes open." Then he spoke to Harris. "I'll appoint you in
command in the engine room," he said. "Heed your signals carefully."

Harris saluted.

"Very well, sir," he said and disappeared.

Von Ludwig motioned to Jack and Frank, who followed him to the bridge.
The officer cast a quick glance over the water and said:

"I guess there is no reason to delay longer. Mr. Chadwick, will you
take the wheel? I'll be with you in a moment to give you your
directions."

Frank moved away. Von Ludwig was just about to address Jack when he
made out another rowboat coming toward the _Bismarck_.

"Hello!" he said aloud. "Wonder what's up now. Guess we'd better wait a
minute."

The rowboat drew closer and Frank discovered it was filled with men.

"Boat crowded with men, sir," he exclaimed.

"So!" exclaimed von Ludwig. "Then I guess we won't wait, after all. You
may get under way, Mr. Templeton."

With this order von Ludwig took his place beside Frank at the whee
