"He hasn't come back this way, or I should have seen him. He must have gone the other way, or else dodged into some side street or door-way.

I'll go back with you."

The two went back together, but it was too late. Martin was by this time at some distance, hurrying towards Fulton Ferry.

Rufus felt that the matter was too serious for him to manage alone, and with reluctant step went back to the office to communicate his loss. A formidable task was before him, and he tried to prepare himself for it.

It would naturally be inferred that he had been careless, if not dishonest, and he knew that his formerly having been a street boy would weigh against him. But, whatever might be the consequences, he knew that it was his duty to report the loss instantly.

CHAPTER XVI.

MR. VANDERPOOL.

Rufus entered the office as Mr. Turner was about to leave it.

"You were rather long," he said. "Were you detained?"

"I wish that was all, Mr. Turner," said Rufus, his face a little pale.

"What has happened?" asked the banker, quickly.

"The box was stolen from me as I was going upstairs to the office of Foster & Nevins."

"How did it happen? Tell me quickly."

"I had only gone up two or three steps when I heard a step behind me.

Turning to see who it was, I was struck violently in the face, and fell forward. When I recovered, the man had disappeared, and the box was gone."

"Can I depend upon the absolute truth of this statement, Rufus?" asked Mr. Turner, looking in the boy's face searchingly.

"You can, sir," said Rufus, proudly.

"Can you give any idea of the appearance of the man who attacked you?"

"Yes, sir, I saw him for an instant before the blow was given, and recognized him."

"You recognized him!" repeated the banker, in surprise. "Who is he?"

Our hero's face flushed with mortification as he answered, "His name is Martin. He is my step-father. He has only just returned from Blackwell's Island, where he served a term of three months for trying to pick a man's pocket."

"Have you met him often since he was released?" asked Mr. Turner.

"He attempted to follow me home one evening from the Academy of Music, but I dodged him. I didn't want him to know where I boarded, for fear he would carry off my little sister, as he did once before."

"Did he know you were in my employ?"

"Yes, sir; I met him day before yesterday as I was coming home from the post-office, and he followed me to the office. He showed me a roll of bills, and said he was getting a hundred dollars a month."

"Now tell me what you did when you discovered that you had been robbed."

"I searched about for Martin with a policeman, but couldn't find him anywhere. Then I thought I had better come right back to the office, and tell you about it. I hope you don't think I was very much to blame, Mr.

Turner."

"Not if your version of the affair is correct, as I think it is. I don't very well see how you could have foreseen or avoided the attack. But there is one thing which in the minds of some might operate to your prejudice."

"What is that, sir?" asked Rufus, anxiously.

"Your relationship to the thief."

"But he is my greatest enemy."

"It might be said that you were in league with him, and arranged to let him have the box after only making a show of resistance."

"I hope you don't think that, sir?" said our hero, anxiously.

"No, I do not."

"Thank you for saying that, sir. Now, may I ask you one favor?"

"Name it."

"I want to get back that box. Will you give me a week to do it in?"

"What is your plan?"

"I would like to take a week out of the office. During that time, I will try to get on the track of Martin. If I find him, I will do my best to get back the box."

Mr. Turner deliberated a moment.

"It may involve you in danger," he said, at length.

"I don't care for the danger," said Rufus, impetuously. "I know that I am partly responsible for the loss of the box, and I want to recover it.

Then no one can blame me, or pretend that I had anything to do with stealing it. I should feel a great deal better if you would let me try, sir."

"Do you think there is any chance of your tracing this man, Martin? He may leave the city."

"I don't think he will, sir."

"I am inclined to grant your request, Rufus," said the banker, after a pause. "At the same time, I shall wish you to call with me at the office of police, and give all the information you are possessed of, that they also may be on the lookout for the thief. We had best go at once."

Mr. Turner and Rufus at once repaired to the police office, and lodged such information as they possessed concerning the theft.

"What were the contents of the box?" inquired the officer to whom the communication was made.

"Chiefly railroad and bank stocks."

"Was there any money?"
