“You go first,” said Bart.

“I won’t,” cried Bruce.

“Nor will I,” said Bart.

Bruce said no more. He stooped down, and clasping Bart in his brawny arms, he jerked him up out of the water. Bart clambered on board, and held out his hand to Bruce. Another instant and the latter stood by his side. Arthur followed at the same time.

“Did you see that?” asked Arthur.

“Yes. Did you?”

“Yes. What was it?”

“Another shovel-month shark—wasn’t it?”

“I don’t think so. It wasn’t the same color. It was white.”

“Perhaps it turned over to bite.”
