"You are mistaken in the person," he said.

"No, I am not. I advise you to restore the money forthwith."

Without a word the thief, finding himself cornered, took from his pocket a roll of bills, which he handed to Walter.

"Is that right?" asked the conductor.

"Yes," said our hero, after counting his money.

"So far, so good. And now, Slippery Dick," he continued, turning to the thief, "I advise you to leave the cars at the next station, or I will have you arrested. Take your choice."

The detected rogue was not long in making his choice. Already the cars had slackened their speed, and a short distance ahead appeared a small station. The place seemed to be one of very little importance. One man, however, appeared to have business there. Walter saw his quondam acquaintance jump on the platform, and congratulated himself that his only loss was a porte-monnaie whose value did not exceed one dollar.

I will only add that the conductor on seeing the pocket-book thrown away had thought nothing of it, supposing it to be an old one, but as soon as he heard of the robbery suspected at once the thief and his motive.
