O, my boy! do you wish to make a dollar?"

"I do, sir—indeed I do."

"What is your name?"

"Will, sir."

"Well, Will, can you keep your mouth shut?"

"Yes, sir."

"Can you be blind, if need be?"

"You mean not to see anything that is not intended for me to see, sir?"

"Yes."

"I understand, sir."

"Well, it is important that this letter reaches a friend of mine, as I cannot go myself, so you take it to the number; can you read?"

"Yes."

"Well, take it to the number on the envelope, and ring the bell sharply three times; then ask for Jerry, the Night Hawk; will you remember the name?"

"Yes, sir—Jerry, the Night Hawk."

"Yes, that's it; and you must give him the letter in person."

"Suppose he is not there, sir?"

"Then find out when he will be, and keep the letter for him; and see, I write on the back here for him to give you a couple of dollars, after which go your way, and forget all about what you have done."

"Yes, sir;" and the boy took the note and turned to depart to the address on the envelope, when he was called back, while the man stood in silent thought.

He was a gentlemanly looking person, with a face, however stamped with dissipation.

In the neighbourhood where he had met the boy, he appeared to be out of place.

For half a moment he stood, gazing at the face of the youngster, and then he said:

"My boy, do you remember to have seen me before?"

"No, sir; and yet it seems as if I had."

"It so seems to me, and your face comes to me like a dream of the past which I cannot recall; but—never mind; go and do as I have told you, and you will get your pay," and the man walked on down the street; but before he had gone far he sprang into a hack, which had evidently been waiting for him, and was driven away.

The boy thus intrusted with what was evidently an important note, was an urchin of twelve; but he looked older, and there was that in his bright, handsome face which denoted both courage of a high order and intelligence beyond his years.

He was poorly, very poorly clad, but his clothing was clean, and he evidently took pride in appearing at his best.

The locality he was in was a hard one, one of the worst localities in the city of New York, and rude, rough characters—men, women and children—were in the streets.

But the lad went on his way without noticing any one, and, as though acquainted with his surroundings, turned into a wretched street that was little more than an alleyway.

He stopped at a certain number and seized the bell knob, which appeared to belong to a bygone age, and in fact the house was a quaint old structure that had long been the abode of poverty.

His three sharp rings, as he had been directed to give, were answered by the door opening, seemingly without human agency, while a gruff voice demanded:

"Well, step inside and tell me what you want?"

The messenger stepped into a small hallway, and saw before him, a few feet distant, another door, while, through an open panel in it peered a man's face.

"I wish to see Jerry, the Night Hawk," explained the youngster.

"What do you want with him?"

"I have a letter for him."

"Give it to me."

"No, sir, for I have orders from my boss to give it only to Jerry."

"All right, you can go up and see him, top floor, right hand side front room," was the reply, and as the man spoke the other door closed behind the boy, the one in his front opened, and he found he was in a hallway, into which no doors opened, except the one through which he had passed, and in the rear was only a pair of stairs occupying the entire width of the narrow passageway.

A dim light came from above somewhere, and the messenger ascended the stairs to the second floor, where he saw doors upon either side.

Ascending to the third floor, he sought the door to which he had been directed, and knocked.

No answer came, and he waited a while and again knocked.

Still no answer, and then his eyes fell upon a small knob, which he pulled and found to be a bell.

Still no response, and the thought came to him to ring it three times, as he had the bell below stairs.

This he did, and instantly he heard a voice behind him.

"Well, youngster, what is it you are after?"

He was startled, and turning saw a man's face at a panel in the door.

"I wish to see Jerry, the Night Hawk," answered Will, promptly.

"Who sent you?"

"That I will tell him," was the cool reply.

"Well, I'm Jerry, the Night Hawk."

The boy looked incredulous, and the man opened the door, and called to him to enter.

This he did, and found himself in a hallway that was perfectly square, and the light came into it from above through a skylight.

There was no door in this hall, except the one by which he had entered, but the man said:

"Is there an answer?"

"Yes, sir," said the boy, when he had meant to say 'no,' but he did not correct himself, and instantly the man tapped three times upon the wooden wall of the hallway.

To the new surprise of the boy one side of it was at once run upward, revealing a small room, and into this the two stepped, the man telling the youngster to follow.

In the room was a cot-bed, a table, and a rough-looking individual stood in one corner, holding a rope in his hand, and which he now let go, the wooden partition, under which they had passed, immediately sliding back into place again.

"Now, lad, the letter," said the man who had entered the room with him.

"Are you Jerry, the Night Hawk?" and the boy looked the man straight in the eyes.

"Yes."

The boy took out the letter and handed it to him, and glancing at the address he broke open the envelope.

What was written within was to the point, and very short, for the man at once said:

"Yes, you are just the boy we want, as the captain says," and he gazed into the handsome, fearless young face before him.

"What do you want me for?" asked the lad.

"That you shall soon know, and if you serve us well, you will be well treated; but if not, then you will have to die, that is all," was the ominous reply of the man, as he seized the boy by the shoulder and dragged him through a door into a large room where were a dozen men, whose scowling faces were turned upon the lad with a look that was wicked and threatening. As he recalled the words of Jerry, the Night Hawk, and beheld the wild, evil looking men about him, the heart of the brave boy shrank with fear, for it needed no words to tell him that he had been led into some trap from which there seemed little chance of escape.
