These curious illusions of the senses were presently succeeded by a period of intense and perfectly normal curiosity. I counted the number of strokes made by the piston in a minute, and found there were about three hundred. I counted the number of puffs from the smoke-stack, and decided correctly that there were four times as many of these as there were piston-strokes, that is, about twenty to the second. Then I counted the oil-cans, the gauges, and made mental photographs of the inside of the cab. From start to finish we made no stop and only slackened our speed twice to "pick up water," this important operation being accomplished with a great splashing by a scoop under the tender, which drops into a trough running lengthwise of the track for about twelve hundred feet, and always kept full to the brim. The scoop is controlled by a lever in the tender, which the fireman directs. In the winter, steam-pipes through the troughs keep the water from freezing. During the whole distance Buchanan scarcely changed his position, and never turned his head. For two hours and thirty-six minutes he stood at the right of the boiler, an immovable figure in gray overalls and black skullcap, his left hand on the throttle, while his right clutched the window to steady him. I never once saw his eyes, which were fixed on the track ahead as if held there by a magnet. No matter how the smoke and cinders poured in through the open windows in front, no matter the bridges and tunnels nor the mad rush of air, his eyes stayed forward always, sweeping the line before us anxiously, constantly on the alert for signals, for switches, for obstructions, for the long tunnel, for the train side-tracked near Poughkeepsie, for the water troughs, for a score of things, the missing any one of which might mean disaster. And, as he watched, silent and motionless, there was one thought in his mind and only one, whether we would make up the lost nine minutes and get into Albany on time. Al's thoughts were the same, and, like one of Dante's demons, he worked at the coal and the fire and the water, now oiling the drivers, now looking at the gauges, ever busy and ever growing blacker and oilier in hands and face.
