Its hand was rising rapidly. First, it showed thirty, then twenty, then ten, and then five feet.

“We’re awash, sir,” came a surprised hail from the conning-tower the next instant.

“Of course we are,” cried Channing Lockyer delightedly. “I didn’t tell you boys we were going to rise, because I wished to try to take you by surprise. I see I have succeeded in doing so.”
