When Bunty was six, his father was holding down the swivel-chair in the Master Mechanic’s office of the Hill Division, and Bunty’s allegiance to the shops wavered. Not from any sense of disloyalty; but with his father’s promotion a new world opened to Bunty, and fascinated him. It was now the yard-shunter and headquarters that engaged his attention. The years, too, brought other changes to Bunty. The curls had disappeared, and his hair was cut now like his father’s. Long stockings had replaced the socks, and he wore real trousers; short ones, it is true, but real trousers none the less, with pockets in them. When school was over, he would fly up and down the yard on the stubby little engine, and Healy, doing the shunting then and forgetting past grievances, would let Bunty sit on the driver’s seat. In time Bunty learned to pull the throttle, but the reversing-lever was too much for his small stature, and the intricacies of the “air” were still a little beyond him. But Healy swore he’d make a driver of him--and he did. The evenings at the office Bunty loved fully as well. Headquarters were not much to boast about in those days. That was before competition forced a doubletrack system, and the train-dispatcher, with his tissue sheets, still held undisputed sway. They called them “offices” at Big Cloud out of courtesy--just the attic floor over the station, with one room to it. The floor space each man’s desk occupied was his office. Here Bunty would sit curled up in his father’s chair and listen to the men as they talked. If it was anything about a locomotive, he understood; if it was traffic or bridges or road-bed or dispatching, he would pucker his brows perplexedly and ask innumerable questions. But most of all he held Spence, the chief dispatcher, in deep reverence. Once, to his huge delight, Spence, holding his hand, had let him tap out an order. It is true that with the O. K. came back an inquiry as to the brand the dispatcher had been indulging in; but the sarcasm was lost on Bunty, for when Spence with a chuckle read off the reply, Bunty gravely asked if there was any answer. Spence shook his head and laughed. “No, son; I guess not,” he said. “We’ve got to maintain our dignity, you know.” That winter, on top of the regular traffic, and that was not light, they began to push supplies from the East over the Hill Division, preparing to double track the road from the western side of the foothills as soon as spring opened up. And while the thermometer crept steadily to zero, the Hill Division sweltered. Everybody and everything got it, the shops and the road-beds, the train crews and the rolling-stock. What little sleep Carleton, the super, got, he spent in formulating dream plans to handle the business. Those that seemed good to him when he awoke were promptly vetoed by the barons of the General Office in the far-off East.
