"He wants to say that he told me so," Ned said to Jimmie. "Go back and tell him that he ought not to be afraid of his friends on board the Shark."
"Gee!" the little fellow replied. "If he don't behave himself, I'll turn the hose on him. He ought to have a salt water bath, anyway. For a long time he's been tryin' to give us one!"
"Let him alone," Ned ordered.
This second upheaval of the water had swung the Shark around so that the door to the water chamber was in view from the Sea Lion. The boys saw that it was open, probably left in that way for the return of the man who had gone down in the water suit.
The light, shining from the main cabin, filtered through the chamber, which was, of course, under water, only a few inches of the conning tower of the submarine now being above the surface.
"Can they shut that door from the cabin?" Frank asked.
"I presume so," Ned replied. "They ought to be able to shut the door and empty the room as well."
"That can't be done on the Sea Lion," Frank said.
"No, but that is a detail that was overlooked in the construction of the boat. I was just learning to run the craft, and did not observe the deficiency."
"Well," Frank went on, "they are closing the door, but they are not doing a good job at it. Say," he added, grasping Ned's arm, "I'll bet the machinery connecting with the door from the cabin is broken!"
