"I guess Ferris kept his word," he muttered. "He said he was going to fix the boy. I wish he had killed the tramp."

That afternoon dragged heavily, but at last it was time to close up. Mr.

Sumner hardly spoke to either when they bade him good-evening.

Hardwick walked up Wall Street, and then turned into Na.s.sau, instead of continuing to Broadway.

Suddenly an idea entered Hal's head to follow Hardwick.

Despite all the evidence pointing in other directions, the youth thought Hardwick either guilty of the robbery or else that the book-keeper knew much concerning it.

Hardwick continued up Na.s.sau Street until he reached Park Row.

Hal kept out of sight behind the man, and presently Hardwick continued up Park Row until he came to one of the side streets just beyond the entrance to the Brooklyn Bridge.

He turned into this street, piled high on either side with dirty snow, and then entered one of the worst thoroughfares in New York City.

By this time it was quite dark, and Hal had to keep close, for fear of losing sight of his man. He was now thoroughly interested, for he knew Hardwick boarded somewhere uptown, and it must be some special business that would bring the book-keeper to this part of the city on such a disagreeable evening.

At length Hardwick paused and glanced behind him. As soon as he saw the movement the boy stepped behind a bill-board out of sight.

Presently Hardwick continued on his way, walking faster than ever. The youth increased his speed.

"Hi! look sharp there!"

Hal was just about to cross a street when he almost ran into a heavy truck. He stepped back, and allowed the truck to pa.s.s. When he reached the opposite curb Hardwick had disappeared.

"He must have gone on straight ahead," thought the youth. "I will soon catch up to him again."

But though he continued onward for more than a block, he saw nothing of the book-keeper.

He looked up and down the side streets, and tried to peep into the curtained windows of several saloons that were close at hand.

"He must have gone in somewhere, that's certain," said Hal to himself.

"I wonder if he discovered that I was following him?"

This last thought disturbed the youth not a little. His experience with Hardwick in the office had convinced him that the book-keeper was an evil man when aroused.

Slowly he retraced his steps, not certain if he could find his way back to Park Row, a spot he had got to know fairly well since his coming to the metropolis.

He was just pa.s.sing a place where a new building was in the course of construction when a peculiar noise to one side of him attracted his attention. By instinct he jumped toward the gutter. The next instant a ma.s.s of bricks came tumbling down. One struck him on the head, and this knocked him insensible.

CHAPTER VII.

HAL DETERMINES TO INVESTIGATE.

When Hal came to his senses he found himself in the arms of a boy slightly taller than himself, who was doing all in his power to restore consciousness by the application of snow to Hal's forehead.

"What--what----" he began.

"Good! yer come around at last, have yer?" cried the boy. "Blessed if I didn't think yer was a goner."

Hal put his hand up to his head.

"Where am I?" he asked, faintly.

"Yer all right; don't worry," replied the tall boy. "Don't yer remember me?"

Hal pulled himself together, and looked at the speaker.

"Jack McCabe!" he cried.

"Yer struck it fust clip. Say, wot was der matter wid yer? Yer couldn't have been froze, coz it wasn't cold enough."

"I was struck on the head."

"Gee crickety! Who struck yer?"

"I--I--n.o.body, I think. It was some bricks from that building."

"Oh, dat's it. How do yer feel now?"

"Awfully light-headed," responded Hal, telling the exact truth.

"Kin yer walk about a block? I only live jest around dat corner."

Hal started at these words.

"You do?"

"Yes."

"Tell me, is your father janitor of a building down in Wall Street?"

"O' course not. Didn't I tell yer we lived here?"

Hal looked relieved.

"What has that got to do with it?" he asked, curiously.

"Why, dem janitors all lives in der buildin's da takes care of,"

explained Jack.

"The reason I ask is because there is a Daniel McCabe janitor of the building I work in."
