"Wild," he whispered, and his whisper was like an awe-stricken sob. "Running wild on the Devil's Slide. _No one in the cab_. Oh, my God!" There was a look on Carleton's face no words could describe--it was gray, gray with a sickness that was a sickness of his soul; but his words came crisp and clear, cold as steel, and without a tremor. "Clear the line, Spence. Get out the wrecking crew, and send the callers for the doctors--that's all that's left for us to do." But while Big Cloud was making grim preparations for disaster, Beezer in no less grim a way was averting it, and his salvation, together with that of every soul aboard the train, came, in a measure at least, from the very source wherein lay their danger--the speed. That, and the fact that the pressure MacAllister had thought would drop before the summit was reached, was at last exhausting itself. The cab was less dense, and the speed whipping the wind through the now open window helped a whole lot more, but it was still a swirling mass of vapor. Beezer lowered himself in, his foot touched the segment, and then found the floor. The 1016 was rocking like a storm-tossed liner. Again there came the sickening, deadly slew as she struck a curve, the nauseating pause as she hung in air with whirring drivers. Beezer shut his eyes and waited. There was a lurch, another and another, fast and quick like a dog shaking itself from a cold plunge--she was still on the right of way. Beezer wriggled over on his back now, and, with head hanging out over the running board, groped with his hands for the levers. Around his legs something warm and tight seemed to clinch and wrap itself. He edged forward a little farther--his hand closed on the throttle and flung it in--a fierce, agonizing pain shot through his arm as something spurted upon it, withering it, blistering it. The fingers of his other hand were clasped on the air latch and he began to check--then, unable to endure it longer, he threw it wide. There was a terrific jolt, a shock that keeled him over on his side as the brake-shoes locked, the angry grind and crunch of the wheel tires, and the screech of skidding drivers. He dragged himself out and crouched again on the running board. Behind him, like a wriggling snake, the coaches swayed and writhed crazily, swinging from side to side in drunken, reeling arcs. A deafening roar of beating flanges and pounding trucks was in his ears--and shriller, more piercing, the screams of the brake-shoes as they bit and held. He turned his head and looked down the right of way, and his eyes held there, riveted and fascinated. Two hundred yards ahead was the worst twist on the Slide, where the jutting cliff of Old Piebald Mountain stuck out over the precipice, and the track hugged around it in a circle like a fly crawling around a wall.
