The stranger gathered his cloak about him, and, stepping out on the platform, jumped from the car. Just at that moment Ben put his hand into his pocket, and instantly discovered the loss of the letter. He immediately connected it with the departure of his fellow-passenger, and, with a hasty ejaculation, sprang from the car, and started in pursuit of him.


CHAPTER XIX.

WHICH IS THE GUILTY PARTY?

It was an exciting moment for Ben. He felt that his character for honesty was at stake. In case the pickpocket succeeded in getting off with the letter and money, Mr. Sampson would no doubt come to the conclusion that he had appropriated the fifty dollars to his own use, while his story of the robbery would be regarded as an impudent fabrication. He might even be arrested, and sentenced to the Island for theft. If this should happen, though he were innocent, Ben felt that he should not be willing to make himself known to his sister or his parents. But there was a chance of getting back the money, and he resolved to do his best.

The pickpocket turned down a side street, his object being to get out of the range of observation as soon as possible. But one thing he did not anticipate, and this was Ben's immediate discovery of his loss. On this subject he was soon enlightened. He saw Ben jump from the horse-car, and his first impulse was to run. He made a quick movement in advance, and then paused. It occurred to him that he occupied a position of advantage with regard to his accuser, being respectably dressed, while Ben was merely a ragged street boy, whose word probably would not inspire much confidence. This vantage ground he would give up by having recourse to flight, as this would be a virtual acknowledgment of guilt. He resolved instantaneously to assume an attitude of conscious integrity, and frown down upon Ben from the heights of assumed respectability. There was one danger, however, that he was known to some of the police force in his true character. But he must take the risk of recognition.

On landing in the middle of the street, Ben lost no time; but, running up to the pickpocket, caught him by the arm.

"What do you want, boy?" he demanded, in a tone of indifference.

"I want my money," said Ben.
