"All this," said Matt finally, "may be either the result of accident or design. I think it would be well for us to find out as much as we can before we get too far down the river."
"How'll you find out, mate?" queried Dick.
"By talking with the girl. Wait here for me. I'll go and have that talk with her now."
As Matt started away, the girl herself suddenly entered the cabin, and she was bringing Captain Sixty with her.
Matt halted and drew back to the side of his friends. The girl looked toward the boys, smiled, said something to her companion, and hurried him across the cabin.
"Hello, Motor Matt!" cried Miss Harris. "I was afraid you'd got left, and was just telling Uncle Jim here that I didn't know what Uncle Archie would say when he found you had not gone to Belize."
Uncle Jim! Miss Harris had called this Sixty person her Uncle Jim! While Matt was puzzling over this, the girl had drawn close and was introducing Captain Sixty.
"I'll be blowed, girl," bellowed Uncle Jim, "if I need any introduction to Motor Matt. We've met before, eh, messmate? Hand us your fist till I give it a friendly shake. Why, I hadn't the least idee you was mixed up in this affair of Townsend's! Ain't it astonishin' how things fall out, now and again?"
"I should say so," answered Matt. "This is your uncle, Miss Harris?" he added to the girl.
"Why, yes, of course!" she laughed.
