“I was afraid he had heard us,” spoke the tall lad. “We had a narrow escape.”

“That’s what we did,” agreed Ted.

The news was received by Ned and Bob with satisfaction.

“I’m glad we’re going to do something besides sit around this submarine waiting,” commented Ned.

“And I’d like to try my hand at cooking again,” confessed Bob, with a sigh. “They won’t let me in the galley here.”

“Well, that all may be changed in a few hours,” said Jerry hopefully.

“Oh, I’m so glad!” cried Grace, whose face showed traces of tears. “Then we will see our friends again, Papa.”

“Yes, my girl! It has been a severe strain on you, but you’ve borne up well. It was a lucky day when the boys came aboard.”

Jerry rapidly told of his experience with the crew, and the decision arrived at. On Mr. Sheldon’s advice the boys got together a quantity of stout rope, which was placed in readiness to bind Dr. Klauss after he should have been subdued.

“We’ll lock him in his own cabin,” went on Bob’s uncle, “and we’ll have to arrange to stand guard over him. Maniacs are very tricky, and he may escape. About his two friends—I think, with the members of the crew, that they will give no trouble. Now, who is going to do the actual attacking, Jerry?”
