“I know that,” spoke Bob, with a grateful look. “Our folks say it’s mighty kind of you boys to take this trouble.”

“Huh! Why wouldn’t we?” demanded Ned. “I guess we’re as much interested in this rescue as you are, Bob Baker.”

“Well, it’s good of you. I’m glad it was the storm that sunk the Hassen, and not that German submarine. If that boat had rammed the steamer she might have gone down so quickly that no one would have had a chance for life.”

“Oh, try to forget that submarine,” protested Jerry. “You’re getting it on the brain.”

“Like Professor Snodgrass,” spoke Ned. “Only a little while ago, when I went in the house, Jerry, to get some of that high tension wire, he asked me if we had started on it yet.”

“What’d you tell him?”

“That we had other fish to fry. I spoke of our trip in the Comet and of course he wanted to come along. He said if he couldn’t get his hermit crab specimens right away he might find some new bugs up in the air. So I told him he was welcome to come.”

“That’s right,” agreed Jerry. “We may need his help if it comes to a rescue.”

“The only trouble is,” remarked Bob, with a smile, “that if we sight that submarine again the professor may insist on being put aboard so he can get to the bottom of the sea. What will we do then?”

“Wait until it happens—worry then,” advised Jerry, with a laugh. “I don’t imagine that submarine is within a thousand miles of us.”
