Next morning at seven, the new yard master took hold. Callahan had intimated that the night air in the yard, it being low land, was miasmatic, and that Shockley had maybe better try for a while to do his switching in the daytime. Just before the appointed hour in the morning, the assistant had looked out on his unlucky yard; he thought to himself that if that yard didn't drive a man to drink nothing ever would. Piled shanty high with a bewildering array of material, it was enough to take the heart out of a Denver switching crew.

While he stood at the window he saw their plug switch engine, that had been kicked out of every other yard on the system, wheeze out of the roundhouse, saw the new yard master flirt his hand at the engineer, and swing up on the footboard. But the swing—it made Callahan's heart warm to him. Not the lubberly jump of the hoboes that had worried the life out of him all summer, even when the cattlemen didn't bother. It was the swing of the sailor into the shrouds, of the Cossack into the saddle, of the yacht into the wind. It was like falling down or falling up or falling on—the grace of a mastery of gravitation—that was Shockley's swing on the footboard of the yard engine as it shot snorting past him.

"He's all right," muttered Callahan. It was enough.

A man who flipped a tender like that was not like to go very wrong even in that chaos of rails and ties and stringers and coal.

"Now," continued Callahan to himself, timidly hopeful, "if the cuss only doesn't get to drinking!" He watched apprehensively, dreading the first time he should see him entering Pat Barlie's place, but Shockley didn't appear to know Pat had a place. The cowboys, too, watched him, waiting for his lamp to gleam at night down in the yard, but their patience was strained for a long time. Shockley got all his work done by daylight.

To the surprise of Callahan, and probably on the principle of the watched pot, the whole winter went without a brush between Shockley and the cowboys. Even Peg Leg Reynolds let him alone. "He's the luckiest fellow on earth," remarked Callahan one day at McCloud in reply to a question from Bucks about Shockley. "There hasn't a shot been fired at him all winter."

"He wasn't always lucky," commented Bucks, signing a batch of letters.

"He came from Chicago," Bucks went on, after a silence. "He was switching there on the 'Q' at the time of the stock-yards riots. Shockley used to drink like a pirate. I never knew just the right of it. I understood it was in a brawl—anyway, he killed a man there; shot him, and had to get away in a hurry. I was train master. Shockley was a striker; but I'd always found him decent, and when his wife came to me about it I helped her out a little; she's dead since. His record isn't just right back there yet. There's something about the shooting hanging over him. I never set eyes on the fellow again till he struck me for a job at McCloud; then I sent him up to you. He claimed he'd quit drinking—guess he had. Long as he's behaving himself I believe in giving him a chance—h'm?"

It really wasn't any longer a case of giving him a chance; rather of whether they could get on without him. When the Colorado Pacific began racing us into Denver that summer, it began to crowd even Shockley to keep the yard clean; he saw he would have to have help.

"Chris, what do they give you for tinkering up the ties?" asked Shockley one day.
