"No, he hasn't. My watch cost five hundred dollars."

"I have a very fine timepiece, I don't mind admitting," spoke the well-dressed youth. "It was given to me by my father, who is quite wealthy."

"I'd like to see it," said Mr. Baker.

By this time an engine, with some parts to repair the broken locomotive, had arrived from a near-by freight yard. The train crew had made the adjustments, and the express was almost ready to proceed. Nearly all the passengers, who had alighted, had again boarded their cars.

"I shall be pleased to show you my watch," said Mr. De Royster, drawing out a heavy gold affair. "I think you will readily agree with me, that it is a valuable one."

He passed it to Mr. Baker, and, from where he stood Roy could see the swindler slip it into his pocket and substitute for it one somewhat like it, but, probably made of brass instead of gold. Mr. Baker turned his back, pretending to be trying to get a good light, while he compared his watch with that of Mr. De Royster.

"That's a fine diamond pin in your tie," said Tupper, indicating the stone in the salesman's tie.

"Yes. Would you like to look at it? It is of very pure color."

He drew out the gem, and, unsuspectingly passed it to Tupper.

At that instant the locomotive engineer blew two warning whistles, so that the lagging passengers might get on the train, which was about to start.
