His arms slapped the water aimlessly and he was going down again when Sammy grabbed him by the shoulder, while at the same time Frank got a grip on the other arm.
SAMMY GRABBED HIM BY THE SHOULDER.
"What's the matter, Bob?" panted Sammy.
"C-cramps, I guess," responded Bob, weakly.
"I'll tell you what to do," said Frank. "Turn over on your back, Bob, and try to float. Then Sammy and I will take turns in towing you to shallow water."
Luckily, Bob had sense and self-control enough to do this, though for a moment he felt a wild temptation to grasp his comrades frantically. But he knew that this might make all three of them drown, and he did as Frank had directed. They were soon back in the shallower water, and then the tired and frightened boys found a foothold and all dragged themselves up on the sand where they fell in a heap.
Sammy was the first to speak.
