"Ever do any racing?"
"A little."
"Here, let's see if you can svim fifty yards fast."
"O, but I'm not in training."
"Don't make no difference about dat. Svim up one length and back again. I see your time. Come on, I tink you can svim fast."
Frank, thus urged, took a racing dive, paddled easily to the other end of the pool, turned leisurely and came back to the starting point.
"Umph!" grunted the swimming instructor. "Dirty-five seconds, dat's bad. You ought to do it five seconds bedder!"
Frank grinned, thinking he was nicely out of the difficulty, for he argued with himself that in justice to his work he could not give the time necessary this year at least to go in for swimming.
But he reckoned without Max who stood squinting at him.
