manager corroborated all that Dick had already told about the circumstances of the case.

"But you have no evidence against the man," said the policeman.

"I understand that he brought a diamond here to pawn. I'd like to see it," said the manager.

The officer handed the five-carat stone to him. He looked it over and handed it to the salesman.

"Is that the stone that you missed?" he said.

"Yes, that appears to be the stone," said the clerk.

"How do you recognize it?" asked the officer, who believed that all unset diamonds of a size looked as much alike as all peas of a size. The salesman explained that it was a part of his business to make himself familiar with the looks and quality of all diamonds he had charge of.

"Well, this may or may not be the stone you assert is missing from your stock," said the policeman; "but as long as you can't show that this man took it, I don't see how I can run him in without a regular warrant."

"I think I can throw some light on the matter," said Dick at this point.

All hands looked at him.

"Here's a piece of gum which I saw that man throw into the street after picking something out of it," he said, handing the gum to the manager. "It evidently held the diamond, for it bears a clear impression of a five-carat stone."

"It does, indeed!" said the manager.

"The lady who was in the store looking at rings when you sent me on the errand came up to that man and handed him that piece of gum. It was the singularity of their meeting that aroused my suspicions and caused me to watch and then follow them to this place, particularly after I picked the gum up and saw the impression of a diamond in it. I judged at once that the man must have hidden the stone in the gum and left it somewhere about the counter where the lady found it afterward and brought it to him."

Dick's words seemed to make the matter quite clear to the manager, who was familiar with many of the tricks adopted by diamond thieves to ply their vocation without detection.

"The gum business is an old trick," said the manager. "It's a wonder it did not occur to you," he added, looking at the salesman. "When a thief comes into a store he sometimes carries a piece of adhesive gum like that," he explained to the policeman. "The first thing he does is to attach it to the bottom of the showcase, out of sight. Then he watches his chance, and if he is a sufficiently expert sleight-of-hand artist, he manages at some time during his inspection of the stones to convey a diamond to the gum and force it into it. When the diamond is afterward missed he cheerfully submits to a search, for the stolen stone is not on his person. Later he sends a confederate into the store to get the gum, under cover of an intention to make some kind of a purchase, other than diamonds, at that counter. In this case, it is quite clear to me that the lady was the man's confederate. I think I am fully justified in demanding that fellow's arrest at our risk. It is too bad that the woman got away, but I guess we'll be able to find her. You have her description, Dick," he said to the office boy.

"Yes, sir. I'd recognize her on sight."

"Now, officer, you may arrest that man and take him to the police station. We will go with you and make the charge," said the manager.

"All right," said the policeman. "Come on, my man, you'll have to go with me."

That settled the case as far as the pawnshop was concerned, and the party directly interested started with the officer and the prisoner for the Brooklyn Bridge station. The charge was made against the man, who gave his name as Jack Hurley, and he was locked up pending his removal to the Tombs prison. The manager, salesman and Dick then returned to the store. The former complimented the office boy on his smartness in bringing the thief to justice, which would result in the ultimate return of the valuable diamond to the store. Mr. Bacon, who had been informed of the theft of the stone, was duly put in possession of Dick's clever work toward its recovery and the punishment of the thief and, it was hoped, his accomplice. He sent for his office boy and added his compliments to those of the manager.

"You're a clever boy, Dick," he concluded, "and I'll see that you lose nothing through your devotion to my interests. That's all."

Dick got up and returned to his duty.

CHAPTER VI.—Knocked Out.

Of course, the robbery of the diamond and Dick's brilliant rounding up of the thief got into the afternoon papers. All the merchants and clerks of the jewelry district downtown were talking about it before closing-up time. Dick Darling, the boy in the knickerbockers, was voted an uncommonly smart lad, and people who knew Mr. Bacon told him so. One of Bacon's clerks after reading the story in the paper called Dick over and showed it to him. Dick bought a couple of papers on his way home and read both accounts. When he got to the house he handed one of the papers to his mother and called her attention to the story. She read it and was, of course, much surprised. Dick supplied her with many additional particulars not in the paper.

"Mr. Bacon must be greatly pleased with you," said Mrs. Darling.

"Yes, mother, I dare say he thinks I'm all to the good."

His sisters nearly always read the evening paper on their way home. The diamond theft having been given an important position on the first page of the papers they bought that afternoon, it attracted their attention right away. When they saw that the theft had taken place at the store where their brother was employed, they read on with added interest. Then when they saw Dick's name in cold type they became still more interested. As he proved to be the chief figure in the story, next to the thief, they grew quite excited over the story. Had they been together, their exclamations and talk would have attracted attention in the car, but they seldom came together on the same car or train, and so they waited till they reached home to loosen up their tongues. And what a jabbering there was in the little flat when they arrived within a few minutes of each other. They surrounded their brother and plied him with questions, till he broke away, declaring that they made his head ring. Their excitement lasted all through supper. The sum total of their opinion was that Dick was a regular hero, and they were awfully proud of him. The morning papers repeated the story with a few additional details, and Dick read it over again. Then he turned his attention to the other news.

He generally saw everything that was in the papers, though he didn't read everything, because he hadn't time to do so. A paragraph, however, caught his attention this morning which interested him. It told of the escape of Bulger and Parker from the Carlin jail. The jail was an old one, and they had been lodged in a cell the window bars of which proved to have become defective. At any rate, during the short time they were locked up there, they managed to loosen two of the bars so they could be removed during the night. From the window they reached the jail yard, scaled the tall wall with its rusty spikes, and got away. Their escape was not discovered until morning, when officers were at once sent out to look for them.

Dick wondered if they would succeed in getting clear off. About eleven that morning Dick, the manager and the diamond salesman, went to the Tombs police court to appear against Jack Hurley, the diamond thief. He was represented by a cheap lawyer, who employed browbeating tactics in his client's behalf, but did not succeed in shaking the testimony of the witnesses. Dick being the chief witness, the lawyer spared no pains in his efforts to tangle the boy up. Finally he moved that his client be discharged on the ground that there was no real evidence connecting him with the theft of the diamond.
