The bark of the exhaust came quicker and quicker, swelled and rose into the full, deep-toned thunder of a single note. Notch by notch, Dorsay opened out the 1014, notch by notch, and the big mountain racer, answering like a mettlesome steed to the touch of the whip, leapt forward, ever faster, into the night. Now the headlight played on shining steel ahead; now suddenly threw a path of light across the short, yellow stubble of a rising butte, and Dorsay checked grudgingly for an instant as they swung the curve--just for an instant--then into the straight again, with wide-flung throttle. It was mad work, and in that reeling, dizzy cab no man spoke. The sweep of the singing wind, the wild tattoo of beating trucks, the sullen whir of flying drivers was in their ears; while behind, the derrick crane, the tool car and the coaches writhed and wriggled, swayed and lurched, tearing at their couplings, bouncing on their trucks, jerking viciously as each slue took up the axle play, rolling, pitching crazily like cockleshells tossed on an angry sea. Now they tore through a cut, and the walls took up the deafening roar and echoed and reëchoed it back in volume a thousandfold; now into the open, and the sudden contrast was like the gasping breath of an imprisoned thing escaped; now over culverts, trestles, spans, hollow, reverberating--the speed was terrific. Over his levers, bounding on his seat, Dorsay, tense and strained, leaned far forward following the leaping headlight's glare; while staggering like a drunken man to keep his balance, the sweat standing out in glistening beads upon his grimy face, Stan Willard watched the flickering needle on the gauge, and his shovel clanged and swung; and in the corner, back of Dorsay, bent low to brace himself, thrown backward and forward with every lurch, in the fantastic, dancing light like some tigerish, outraged animal crouched to spring, Flannagan, with head drawn into his shoulders, jaws outthrust, stared over the engineer's back, stared with never a look to right or left, stared through the cab glass to the right of way ahead--stared toward Spider Cut. Again and again, with sickening, giddy shock, wheel-base lifted from the swing, the 1014 struck the tangents, hung a breathless space, and, with a screech of crunching flanges, found the rails once more. Again and again--but the story of that ride is the doctors' story--they tell it best. Dorsay made the run that night from Big Cloud to Spider Cut, twenty-one point seven miles, in _nineteen_ minutes. There have been bad spills on the Hill Division, bad spills--but there have never been worse than on that Friday night when the 505 jumped the rails at the foot of the curve coming down the grade just east of Spider Cut, shot over the embankment and piled the Coast Express, mahogany sleepers and all, into splintered wreckage forty feet below the right of way.
