Bradley started on the run for the next car ahead; and, subconsciously, as he ran, he felt the speed of the train quicken. But that was natural enough—they had been crawling to the summit of Mitre Peak, and, over that now, before them lay a four-percent grade to the level below, one of the nastiest bits of track on the division, curves all the way—only Bull Coussirat was hitting it up pretty hard for a starter.
In the next car the same scene was repeated—the smell of powder smoke, the blue haze hanging listless near the roof out of the air currents; the crouched, terrified foreigners, one with a broken wrist, dangling, where a bullet had shattered it. Pietro, Berserker fashion, was shooting his way through the train.
Bradley went forward more cautiously now, more warily. Strange the way the speed was quickening! The cars were rocking now with short, vicious slews. He thought he heard a shout from the track-side without, but he could not be sure of that.
Through the next car and the next he went, trailing the maniac; and then he started to run again. Stumbling feet, trying to hold their footing, came to him from the top of the car. With every instant now the speed of the train was increasing—past the limit of safety—past the point where he would have hesitated to use the emergency brakes, if there had been any to use—a luxury as yet extended only to the passenger equipment in those days. The Polacks, the Armenians, and the Swedes were beginning to yell with another terror, at the frantic pitching of the cars, making a wild, unearthly chorus that echoed up and down the length of the train.
Bradley's brain was working quickly now. It wasn't only this madman that he was chasing fruitlessly. There must be something wrong, more serious still, in the engine cab—that was Heney, and Carrol, the other brakeman, who had run along the top.
Bradley dashed through the door, and, between the cars, jumped for the ladder and swarmed up—the globe of his lamp in a sudden slew shivered against the car roof, and the flame went out in a puff. He flung the thing from him; and, with arms wide outspread for balance on his reeling foothold, ran, staggered, stumbled, recovered himself, and sped on again, springing from car to car, up the string of them, to where the red flare, leaping from the open fire box in the cab ahead, silhouetted two figures snatching for their hold at the brake-wheel on the front end of the forward car—Heney and Carrol. And as Bradley ran, a thin stream of flame spurted upward from the cab, and there came faintly, almost lost in the thunder of the train, the bark of a revolver shot—and the two figures, ducking instantly, crouched lower.
And then Bradley stood beside the others; and Heney, that no man ever called a coward, clutched at Martin Bradley and shouted in his ear:
"For God's sake, Martin, what'll we do? The throttle was wide at the top of the grade when he threw Bull Coussirat off. We saw it from the cupola. It's certain death to make a move for him!"
But Bradley made no answer. Tight-lipped, he was staring down into the cab; and a livid face stared back at him—the face of the man that he had stopped to look at as they had pulled out of Big Cloud—Pietro—the face, hideously contorted, of a maniac. And on the floor of the cab, stretched out, wriggling spasmodically, Reddy MacQuigan lay upon his back; and Pietro half knelt upon him, clutching with one hand at the boy's throat, pointing a revolver with the other at the roof of the car.
Wild, crazy fast now, the speed was; the engine dancing ahead; the cars wriggling behind; the yellow glimmer of the caboose shooting this way and that like a pursuing phantom will-o'-the-wisp; and from beneath the roofs of the cars rose that muffled, never-ending scream of terror from the Polacks, the Armenians and the Swedes—rose, too, from the roofs of the cars themselves, for some were climbing there. It was disaster absolute and certain not a mile ahead where the track in a short, murderous curve hugged Bald Eagle Peak, with the cañon dropping a thousand feet sheer down from the right of way, disaster there—if they ever got that far!
