"Then let's get right after him, and make him give up that money!" exclaimed Mr. Clayton. "He's got it. Probably he turned the lumber shares into money as soon as he got ashore, for he could easily do that."

"Then with the money due on the note he has about two thousand dollars belonging to——"

"Belonging to Nat!" interrupted Mr. Clayton, "and I'll see that the boy gets it. Come on, don't lose any time. Bumstead may skip out. I didn't like the man when I was in the same crew with him, but I never supposed he was a thief."

"This explains why he did not want Nat to come aboard to work," said the pilot. "He was afraid Mr. Morton's son would discover something."

"And I did, too," put in Nat. "I saw him have my father's wallet."

"That's so; I forgot about that for the moment," cried Mr. Weatherby. "Do you recall that pocketbook, with Mr. Morton's name on it in gold letters?" he asked, turning to Mr. Clayton.

"Indeed, I do. Jim thought a lot of that. Has Bumstead got it?"

"We have every reason to think he has."

"He's a thorough villain," commented Mr. Clayton. "Now don't let's delay any longer, or he may skip out. Let's get a policeman, or a detective, and have him locked up. I'll be a witness against him."

"I guess that's our best plan," assented the pilot. "Well, Nat, you're better off than you thought you were. Two thousand dollars is a neat sum for a lad like you."
