"Avast there, Carl! I'll bet Matt can handle the craft, all right, even if he can't make her do any hand-springs. Do you suppose she'll be sold before we get out to South Chicago?"

"Vell, I hope nod. Meppy ve go righdt avay, hey?"

"Oh, hang it," he went on, "I'm due for a sail on the lake at one o'clock. Merrick, a nice chap I met on the train coming from Denver, invited me to go with him, and I said I'd meet him across the Lake Street viaduct right after dinner.

"Anyvay, Tick, I got to vash oop a leedle, und prush my clothes——"

"So've I. Those swabs handled me a bit rough, although they didn't leave many marks on me."
