"I wonder Mr. Hartley didn't offer you a permanent position in his employ," said Haynes, with a sneer. "Spies are useful sometimes."

"He may give me a position sometime," said Frank, not regarding the sneer.

"You earned it," said Haynes, unpleasantly.

"Thank you," said Frank, knowing that Haynes would be provoked by his appearing to accept the compliment in good faith.

Haynes scowled, but said no more. He drew a morning paper from his pocket, and appeared to be absorbed in reading it.

At Canal street Frank rose to leave the car. He had not yet reached the door, when Haynes sprang to his feet, followed him quickly, and, grasping him by the arm, said, "Not so fast young man! Give me back my pocket-book."

Frank was struck with amazement.

"What do you mean?" he asked, indignantly.

"I mean that you have relieved me of my pocket-book. Gentlemen," turning to his fellow-passengers, "I demand that this boy be searched."

"You can search me if you like," said Frank. "You know very well that your accusation is false."
