As soon as the heated journal has been cooled sufficiently to allow the train to proceed, the engineer blows four blasts on the whistle to recall the brakeman. But, obviously, during the time that he is walking back to the train and the train itself is getting under way, another train may come along at full speed and run into it. So, before he returns, the brakeman sticks a fusee in the middle of the track and lights it. It will burn for ten minutes, and during that time no train may run past the spot, so all danger of accident is avoided. If the breakdown occurs during the daytime, the brakeman will affix two torpedoes to the track instead of using the fusee. The first train which runs over these torpedoes explodes them, and the engineer must at once get his train under control, reduce speed, and look out for a stop signal. A single torpedo is a signal to stop. It was one of these fusees, a number of which are carried in every caboose, which had enabled Jim Anderson to flag Number Two, and lucky it was that he had it, for on a night such as the one before had been, a lantern would almost certainly have failed to be seen. But Jim did not think of that, as he stood there with hanging head. His only thought was that he should not have kept the fusee, that it belonged to the company--that he might be thought a thief. He looked up at last to find the superintendent smiling at him. "My boy," said Mr. Heywood, "if, as you go through life, you never do anything worse than you have done in keeping possession of that fusee, you will never have any reason for remorse. It had been abandoned there by the company; you found it. You were under no obligation to return it. We had lost it through our own carelessness; it may have been missed, but was thought not worth searching for. So dismiss that from your mind. I called you boys before me for a very different purpose than to reproach either of you. In the first place, I want to thank you for your prompt and intelligent action, which saved the road what would probably have been one of the worst wrecks in its history. It is the sort of thing the road never forgets." There were four cheeks now, instead of two, that were flaming red. The praise was almost more embarrassing than the expected blame. "In the second place," continued the superintendent, "I have ordered Lineman Mickey to overhaul your private line and to equip it with up-to-date instruments." He smiled as he looked at the beaming countenances before him. "In the third place," he went on, "I have ordered a box of fusees and another of torpedoes left at your home, Anderson. And they're not to be used on the Fourth of July, either--at least, not more than one or two. They say lightning never strikes twice in the same place, but it's just possible that some day we may want you to flag another train out there, and so we provide you with the means to do it.
