Sam came up and went down again—totally unconscious. Diving, the elder Rover caught his brother around the chest, under the arms.
"Sam, Sam, what is it?" he questioned, and as no reply came back his heart almost stopped beating. What if his brother was dead? The agony of the thought was terrible beyond description.
"Can I help you?" The question came from Tom, who was now at the side of the others.
"Catch hold of one arm, if you will," answered Dick. "He's a dead weight."
"Oh!" The moan came so unexpectedly that both Tom and Dick were amazed. Then of a sudden Sam opened his eyes and clutched Dick by the throat. "Save me!"
Clearly the youngest Rover was out of his mind or he would not have taken such a hold. As it was, Dick was nearly strangled and had to unlock the fingers by sheer force. Then Sam grabbed him again, and it looked as if both would go down to a watery grave.
But now Tom came to the rescue. Swimming up from behind, he caught Sam first under one arm and then under the other, in a back-to-back fashion. Then he bent forward and began to tread water, thus holding his brother's head well out of water.
