Fred found quite a crowd of people up in the gallery, and among them a party of ladies from out of town. They were sightseeing. But there was nothing new to him up there. He wanted to see Broker Manson and watch the rise of B. & H. stock. It took him some time to find Manson in the moving mass of yelling brokers on the floor below. But he finally found him, and for half an hour never took his eyes off of him. He heard him offering fifty-three and finally fifty-four for B. & H. It has thus gone up seven points since the day before. "Bob was right," he said. "He knew what he was about. B. & H. is climbing right up to the top. Hanged if I don't put in another hundred!" and he ran down and out into the street like a young lunatic. In five minutes he had put up another hundred dollars with Broker Tabor for Halsey & Company to buy more B. & H. stock on margin. The stock was bought immediately at 54 1/2-eighteen shares. That done, Fred returned to the Exchange and watched proceedings from the gallery. He kept his eyes on Broker Manson. The big broker was buying the stock at a tremendous rate, all that was offered him. People were coming and going all the time. Fred finally turned to look at a young girl whose voice sounded like music in his ears. She was close by his side. She was accompanied by an elderly couple, evidently her parents. He thought her very beautiful and that she had the most musical voice he had ever heard. She changed positions several times as though looking for somebody on the floor below. He noticed a tall, well-dressed man keeping close behind her, peering over her shoulder at the crowd below. Something in his movements caused Fred to look at him the second time, and to his amazement he saw him pick the pockets of both the ladies. The thief then started to leave, but Fred grabbed his coat-tail, saying: "Here, I saw that little game. It won't go. Ladies, this man has got your pocketbooks." Quick as a flash the thief grabbed him and lifted him above his head. Fred saw he was going to be hurled headlong among the brokers below, and to save himself seized his assailant's coat collar. The two ladies screamed, and the next moment Fred and the pickpocket fell over the gallery and went down in a heap on the yelling brokers below.
