So Ben went along with the others.

All of Camp Amoussock was in bathing-suits, and the four guests were shortly attired likewise. Then began all sorts of water sports. Tom and David and Ben went in for most of the swimming races and the diving contests. Tom took second place in the fifty-yard race, and Ben won the competition for fancy diving. When they came to the tub-race John Tuckerman entered his name.

Amid shouts and cat-calls a dozen tubs set out from the float. The race was to be around a buoy and back to the starting-place. Tuckerman paddled easily, keeping his tub out of the course most of the others were taking. Two tubs jostled, and two boys were upset into the water. Bill Crawford rounded the buoy first, then a small, red-headed boy who sat very still, barely patting the water with careful finger-tips.

“Here comes the Professor!” cried Tom from the beach. “Keep it up, keep it up, Professor! You’re doing wonders!”

Tuckerman reached the buoy. He had found it fairly easy to keep a straight course, but now he had to steer to the left. To do this he tried to give a sidewise sweep with his foot. The tub rocked, rolled. He attempted to counter-balance; and then he was in the water, splashing about and trying to get hold of the tub.

He flopped up on one side, only to slip over on the other. The tub might have been greased, so difficult was it to make the round thing stay in one position for more than a minute. At last he gave up trying to make it behave, and swam, pushing it before him, until he could touch bottom with his feet.

“Never mind, Professor,” said David, as the bedraggled Tuckerman walked up on the beach. “Many a man has found a tub-race his Waterloo.”

There were cheers from the float, and all turned to look. Bill Crawford and the red-headed boy were now neck and neck. Someone shouted, “Now’s your time to spurt, Bill!”

Bill spurted. His tub lost its balance; Bill somersaulted backward into the water. The red-headed boy just managed to avoid Bill’s splashing and paddled along more cautiously than ever, hardly touching the water now, just directing his course with his fingers and toes.

Up to the float he came. He grasped the edge, and a moment later the boy and the tub were on the float, and the race was won.
