You’ve felt it a little if you’ve ever been in the rear Pullman going up--the difference is that a caboose hasn’t any springs to speak of, you understand? Racket enough to raise the dead. You couldn’t hear yourself think. Not so much from the noise of the train or the storm, but from the booming roar of the trailer’s exhaust--like she was trying to cough her boiler tubes out every time the valves slid. Now, there’s just one more thing I want you to get. The engine crew of a pusher naturally can’t see any track, road-bed, or anything of that kind, and it isn’t their business to, either. All they watch is the leader and the intermediate, if there is one. Their headlight plays along over a few cars if it’s high enough, or loses itself on the top of the door or the roof of the caboose if it isn’t, understand? Lee didn’t hear anything. He was sitting bent over with his head between his hands, and it was the current of air from the opening door that made him twist around and look up, thinking it had blown open. I don’t know as you’d call him a coward; maybe yes, maybe no; anyway, he was a white-faced, terrified man that next instant, as he started up from his chair. He never got to his feet. Instead, he shut up like a jackknife, and went down to the floor with a blow over the head from a revolver butt that knocked him senseless. It all happened in a second, but in that second Lee got it with more vividness than a thousand hours would have given him--the great, hulking figure, the water trickling to the floor in little pools from the dripping clothes, the sickly pallor of the face, the thin new skin of the livid scar across the cheek, the sightless eye--Clancy. Lee couldn’t have lain unconscious more than twenty minutes, perhaps it was only fifteen, for it takes about forty minutes to climb the four miles of the Slide, you see. Call it twenty, that allows for what happened before and what happened after. When he came to his senses the light in the bracket lamp was out; blown out by the draft, for the door was open. A stray beam or two from the pusher’s headlight filled the caboose with an uncertain, wavering light--from the jolt and swing, you know, though Lee thought at first it was his head. He tried to get up, but he couldn’t move. He was bound hand and foot, laid out on the flat of his back--helpless. For a minute he was too dazed to understand, then he remembered--Clancy. He stared up into the cupola above him. The swivel chair was empty--Perley had gone. The car trucks were beating a steady _clack, clack-clack_, as they pounded the fishplates; from behind came the full, deep-chested thunder of the trailer’s exhaust; around, the hundred noises of the creaking, groaning, swaying car; without, the patter of rain, the wail of the wind. But over it all, low though it was, came a sound that sent a chill to Lee’s heart.
