In this manner they finally got a number of bills bearing the serial numbers of the notes which had been taken in the train robbery. But this was all the evidence they were able to obtain. Finally when investigations in other directions all failed to bring anything more to light, they determined to arrest White. Accordingly one day they followed him when he got on a street car at his machine shop, and when he got down, at some place of business in the city, they stepped up to him and asked him if his name was White. He said it was; they then asked him to go with them to help in regard to some forgeries. White very willingly said that he would be glad to help them in any way he could and would go if they insisted; but that he knew nothing about any forgeries. They took him to their office in the post-office building. Here he was searched and a roll of these lost bills found in his possession. They were all on the same bank, and, what seemed significant, their serial numbers ran consecutively. When questioned about where he had obtained this money, White replied that he had won it in a poker game from two men who had come into his shop several days before. The two government detectives did not believe this story. They talked to White a long time, but his statement could not be shaken. He described the two men with whom he had played poker, gave in detail their inquiries about some work they wished done at his shop, pointing out the exact time at which the thing occurred, and how the poker game had been led up to. He did not know the names of the two men, but gave precisely their description. The two government detectives remained unconvinced and they determined upon an old experiment. They took White to jail and locked him into a cell. Then they went out, returned by the rear entrance and placed themselves where they could watch the man in the cell. Here White, now very much concerned, fell unconsciously into habits which he had acquired in similar surroundings. He put his hands behind him and began to pace up and down the cell—three steps down, three steps up, slowly, back and forth—his head dropped forward in reflection. The two government detectives watched him for a few minutes, then they went out. They decided that White must have a penitentiary record somewhere on account of his actions in the cell. The two detectives went down to the telegraph office and sent a message to every penitentiary in the United States, giving an accurate description of White, and the holdup in which they believed him to have taken part. They received a reply from the warden of a penitentiary in the northwest, saying that a man answering that description had served time for train robbery. The detectives now determined to take White north for trial. On this trip White escaped from the custody of the officials. The manner of his escape was extraordinarily clever. It was done without a struggle of any character. White simply disappeared.
