When Frank opened his eyes again he found himself in a small boat, with nothing in sight but blue water and the sun beating down upon him, shielded slightly from his face by what he took to to be a coat. The lad rubbed his eyes and attempted to sit up; then fell back with a faint moan.

This sound brought a second figure to his side and Frank felt a hand upon his head as a well-known voice said:

"How do you feel, old man?"

Frank recognized the voice instantly. The speaker was Jack. Things came back to Frank immediately and with an effort he sat up.

"How did I get here?" he demanded. "The last I seem to remember is tipping Davis out of a boat. Then what happened?"

"Then you don't remember a struggle beneath the water?" asked Jack.

Frank racked his brain and a moment later it came back to him.

"Yes, I do," he replied. "I remember he seized me by the legs and I went under. Then I grabbed him by the neck and tried to push him away, but he clung and clung—and clung—and clung—and that's all I can remember."

"And no wonder," declared Jack. "You were under water for five minutes before I could get to you. I got you as you were going down for the last time. I didn't arrive a minute too soon."

"And where are we now?" asked Frank.
