"Too late?"

"Yes, the vessel has sailed for Buffalo. We have been trying to find another ship bound for the same port, that might get in ahead of the freighter, but we couldn't. I guess Bumstead has escaped us for a time, but you can follow him. His ship will tie up in Buffalo for a week."

"But Nat and I have to go aboard the passenger steamer in a few days," said Mr. Weatherby. "We'll have to stay on Lake Huron for a month or more, cruising about. I can't go to Buffalo, and I don't believe it would be safe for Nat to go alone."

"I wish I could," said Mr. Clayton, "but I've got to ship for a trip to Duluth and other ports to-morrow. Even if I didn't have to go, I would have no right to make a complaint against the mate. It would have to be done by Nat, as it's his money."

"That's right," said the detective. "The person whose property is stolen has to make the complaint. But we might wire the Buffalo police to hold the man until one of you can get there. The only trouble is you'd have to swear out a warrant here, and as I understand it, there is only a suspicion against Bumstead."

"We are practically sure he has Nat's money," replied the pilot, "still, there may be some difficulty in causing his arrest, when he is so far away. If we could only send some one to Buffalo, who understood the case, and would know what to do, we could manage. It is out of the question for me to go, and I don't believe Nat could manage matters. The mate would probably get some criminal lawyer, and effect a release, even if he was arrested. It's quite a puzzle."

"I don't see what we can do," added the detective. "If we had been half an hour sooner we could have nabbed him."

Nat, who had hopes of recovering the money that was rightfully his, began to feel discouraged. It looked as if the rascally mate had the best of them.

As the four stood in the street, undecided what to do, a voice hailed Nat, calling out:

"Well, well! If there isn't the lad who saved my boat for me! I'm glad to see you again. How are you?"
