"I give you this hundred dollars for what you did for me at Niagara
Falls. Don't be discouraged. If you ever need a friend, write or
come and see me. I sincerely hope the money will bring you good
fortune."

"What a kind man," murmured Nat, and read the note again. "It was a
mighty lucky thing for me that I went to the Falls."

When he went to bed he felt rich, and he came to the breakfast table
whistling merrily.

"Hullo," cried Dick, "have you struck luck at last?"

"I'm in luck in one way," answered our hero. "Look at that," and he
showed the bank bill.

"Why, it's a hundred dollars, Nat!" And the newsboy's eyes opened
widely.

"Exactly."

"Where on earth did you get the money?"

"A gentleman gave it to me."

"What for?"

"For saving his life. But I didn't know I had it until I went to bed
last night."

"You're talking in riddles."

"I'll explain," and then our hero told as much of the Niagara Falls

"Here is the note," he concluded, showing the slip of paper, which was
unsigned. "I don't feel at liberty to mention the gentleman's name. I
don't think it would be just right."

"A rich man like that would be a fool to commit suicide," said Dick,
bluntly. "What are you going to do with all that money?"

"I don't know. But I shan't squander it, I can tell you that."

"You can go into business for yourself on that amount."

"Maybe, but I guess I had better keep on hunting for a job. I can go
into business for myself when I know more about New York."

"That's where you are sensible. You might lose your money in
double-quick time in your own business."

Nat put the bill away very carefully, and then went out to look for a
position as before. But the week passed and nothing turned up.

On Sunday the country boy attended a church in the vicinity of his
boarding house, and in the afternoon he took a walk to Central Park. In
the evening he stayed at home and read a paper which Dick brought in.

As was natural Nat read over the want advertisements very carefully. It
was not long before he came to one which excited his curiosity. The
advertisement was as follows:

"WANTED--A clerk, to whom a liberal salary will be paid. One
preferred who comes from the country and is not too old. References
expected. Must deposit $100 as security, for which interest will be
paid. Inquire Room 24, Dallax Building, Broadway."

"That ought to
