When the widow Lyons asked Callahan to put Jamie at telegraphing the assistant superintendent nearly fell off his chair. Mrs. Lyons, however, was in earnest, as the red-haired man soon found by the way his shirts were starched. Her son, meantime, had gotten hold of a sounder, and was studying telegraphy, corresponding at the same time with the Cincinnati detective agency for the town and county rights to all "hidden and undiscovered crime," on the Mountain Division--rights offered at the very reasonable price of ten dollars by registered mail, bank draft or express money order; currency at sender's risk. The only obligations imposed by this deal were secrecy and a German silver star; and Bullhead, after holding his trusting mother up for the ten, became a regularly installed detective with proprietary rights to local misdeeds. Days he plied his sounder, and nights he lay awake trying to mix up Pete Beezer and Neighbor with the disappearance of various bunches of horses from the Bar M ranch. About the same time he became interested in dentistry; not that there is any obvious connection between railroading and detective work and filling teeth--but his thoughts just turned that way and following the advice of a local dentist, who didn't want altogether to discourage him, Bullhead borrowed a pair of forceps and pulled all the teeth out of a circular saw to get his arm into practice. Before the dentist pronounced him proficient, though, his mother had Callahan reduced to terms, and the assistant superintendent put Bullhead among the operators. That was a great day for Bullhead. He had to take the worst of it, of course; sweeping the office and that; but whatever his faults, the boy did as he was told. Only one vicious habit clung to him--he had a passion for reading the rules. In spite of this, however, he steadily mastered the taking, and, as for sending, he could do that before he got out of the cuspidor department. Everybody around the Wickiup bullied him, and maybe that was his salvation. He got used to expecting the worst of it, and nerved himself to take it, which in railroading is half the battle. A few months after he became competent to handle a key the nightman at Goose River Junction went wrong. When Callahan told Bullhead he thought about giving him the job, the boy went wild with excitement, and in a burst of confidence showed Callahan his star. It was the best thing that ever happened, for the assistant head of the division had an impulsive way of swearing the nonsense out of a boy's head, and when Bullhead confessed to being a detective a fiery stream was poured on him. The foolishness couldn't quite all be driven out in one round; but Jamie Lyons went to Goose River fairly well informed as to how much of a fool he was.
