“Maybe you’re right!” admitted Jimmie. “Let’s float the boat on an even keel and see. I’m going to dress again!”
Even as the lad hastened to put on his clothes the boys felt a sudden dip made by the submarine. Gradually they descended.
“Hurrah, he did it!” exultantly cried Ned. “Now, where has he gone? I do hope he’ll free the propeller wheel at once!”
“We could rise to the surface even if the propeller is stuck!” declared Harry. “I can pump the ballast all out of the tanks!”
“But if we do that we’ll have to dive overboard to clear the wheel!” protested Frank. “I know that water is good and cold!”
“Wait a minute, boys, and see what the fellow does,” cautioned Ned. “Maybe he wants to help us, so it wouldn’t be nice to run away!”
“Here he is, now!” cried Jack from his position near a porthole. “He’s looking through the glass, and making motions again!”
“I know what he wants!” declared Harry. “He’s making motions for us to unscrew a pipe! He wants us to let in a lot of the ocean!”
“Wait a minute, Harry!” put in Ned. “He’s walking toward his own boat. Let’s see what he’s going to do!”
In a short time their rescuer had reached the side of his own vessel. He stepped into an open door in the side and disappeared.
