“Dock.”
“He’s too exhausted,” replied Bony. “Can’t swim. But Jack’ll get him.”
How long it seemed since Jack had dived down! The swirl he made had subsided, and the water was almost calm again. Anxiously the lads on the float and shore watched to see him reappear. Would he come up alone, or would he bring Dock with him?
“Maybe Jack hit his head on something,” suggested Nat.
“Jack knows how to dive, and it’s deep here,” said Sam. “I guess he’ll come up all right, but——”
He did not finish the sentence. At that moment there was a disturbance beneath the surface of the lake. A head bobbed up.
“There’s Jack!” cried Bony delightedly.
A white arm shot up and began sweeping the water.
“He’s got him!” yelled Nat. “He’s got Dock!”
Sure enough, Jack had come to the surface, encircling in his left arm the unconscious form of Dock Snaith, while with his sturdy right he was swimming slowly toward the float.
