"No, I couldn't swim so far," cried Bob suddenly.

"It would take a strong man who could keep on for hours to do that." "I tell you that you could do it," cried Bigley, who seemed to be quite passionate now.

"Don't talk like that, Bob, or you'll frighten Sep Duncan out of trying." "I'm not going to try," I said gloomily.
