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 wheel and produced a chart. The bell in the engine room tinkled. A moment later the engines began to move and the Bismarck slipped easily through the water.
Came a hail from the rowboat.
"Wait a moment, there!"
Von Ludwig paid no attention to this call. The Bismarck gathered headway.
"Haven't time to talk to you fellows," said von Ludwig. "We want to be a long ways from here before daylight."
