“Lots is up!” exclaimed Ted, vindictively. “We’re in a submarine run by a lunatic—that’s what’s up!”

“Have you just found that out?” asked Jerry, realizing that now was the time to strike for liberty.

“No, we’ve suspected it for some time,” said Bill. “But since you folks came aboard he’s got worse.”

“And now it’s the limit!” added Tom Flynn.

“Why?” Jerry asked.

“He’s just given orders,” went on Ted, “that he’s going to test this boat to the limit. He says he’s going to try to get to the bottom of the sea in a place where it’s two miles, or more, deep, and he’s going to see how long he can go without refilling the air tanks. We’ve got orders to hold on until something busts, and if I had my way something would bust right soon—and it would be crazy Dr. Klauss, too!”

“Hush!” warned Bill.

“I don’t care if he does hear me!” went on Ted. “I’m sick and tired of him!” and he tossed a monkey wrench down with a bang. “I say let’s take these boys and their friends into our plan.”

“What plan is that?” asked Jerry, hopefully, though he could almost guess, now.
