"Get in there, you blamed idiot," roared Neighbor presently at Jimmie. "Get in and fire her; and if you don't give Sollers two hundred and ten pounds every inch of the way I'll set you back wiping."

Jimmie winked furiously at the proposition while it was being hurled at him, but he lost no time climbing in. The 1012 was drumming then at her gauge with better than two hundred pounds. Adam Shafer, conductor for the run, ran backward and forward a minute examining the air. At the final word from his brakeman he lifted two fingers at Sollers; Oliver opened a notch, and Jimmie Bradshaw stuck his head out of the gangway. Slowly, but with swiftly rising speed, the yellow string began to move out through the long lines of freight cars that blocked the spurs; and those who watched that morning from the Piedmont platform, thought a smoother equipment than Bucks's mail train never drew out of the mountain yards.

Jimmie Bradshaw jumped at the work in front of him. He had never lifted a pick in as swell a cab. The hind end of the 1012 was big as a private car; Jimmie had never seen so much play for a shovel in his life, and he knew the trick of his business better than most men even in West End cabs, the trick of holding the high pressure every minute, of feeling the drafts before they left the throttle; and as Oliver let the engine out very, very fast, Jimmie Bradshaw sprinkled the grate bars craftily and blinked at the shivering pointer, as much as to say, "It's you and me now for the Yellow Mail, and nobody else on earth."

There was a long reach of smooth track in front of the foothills. It was there the big start had to be made, and in two minutes the bark of the big machine had deepened to a chest tone full as thunder. It was all fun for an hour, for two hours. It was that long before the ambitious fireman realized what the new speed meant: the sickening slew, the lurch on lurch so fast the engine never righted, the shortened breath along the tangent, the giddy roll to the elevation and the sudden shock of the curve, the roar of the flight on the ear, and, above and over it all, the booming purr of the maddened steel. The canoe in the heart of the rapid, the bridge of a liner at sea, the gun in the heat of the fight, take something of this—the cab of the mail takes it all.

When they struck the foothills Sollers and Jimmie Bradshaw looked at their watches and looked at each other like men who had turned their backs on every mountain record. There was a stop for water, speed drinks so hard, an oil round, an anxious touch on the journals; then the Yellow Mail drew reeling into the hills. Oliver eased her just a bit for the heavier curves, but for all that the train writhed frantically as it cut the segments, and the men thought, in spite of themselves, of the mountain curves ahead. The worst of the run lay ahead of the pilot, because the art in mountain running is not alone or so much in getting up hill; it is in getting down hill. But by the way the Yellow Mail got that day up hill and down, it seemed as if Steve Horigan's dream would be realized, and that the 1012 actually would pull the stamps off the letters. Before they knew it they were through the gateway, out into the desert country, up along the crested buttes, and then, sudden as eternity, the wheel-base of the 1012 struck a tight curve, a pent-down rail sprang out like a knitting-needle, and the Yellow Mail shot staggering off track into a gray borrow-pit.

There was a crunching of truck and frame, a crashing splinter of varnished cars, a scream from the wounded engine, a cloud of gray ash in the burning sun, and a ruin of human effort in the ditch. In the twinkle of an eye the mail train lay spilled on the alkali; for a minute it looked desperate bad for the general manager's test.

It was hardly more than a minute; then like ants out of a trampled hill men began crawling from the yellow wreck. There was more—there was groaning and worse, yet little for so frightful a shock. And first on his feet, with no more than scratches, and quickest back under the cab after his engineer, was Jimmie Bradshaw, the fireman.

Sollers, barely conscious, lay wedged between the tank and the footboard. Jimmie, all by himself, eased him away from the boiler. The conductor stood with a broken arm directing his brakeman how to chop a crew out of the head mail car, and the hind crews were getting out unaided. There was a quick calling back and forth, and the cry, "Nobody killed!" But the engineer and the conductor were put out of action. There was, in fact, only one West End man unhurt—Jimmie Bradshaw.

The first wreck of the fast mail, there have been worse since, took place just east of Crockett's siding. A westbound freight lay at that moment on the passing track waiting for the mail. Jimmie Bradshaw, the minute he righted himself, cast up the possibilities of the situation. Before the freight crew had reached the wreck Jimmie was hustling ahead to tell them what he wanted. The freight conductor demurred; and when they discussed it with the freight engineer, Kingsley, he objected. "My engine won't never stand it; it'll pound her to scrap," he argued. "I reckon the safest thing to do is to get orders."

"Get orders!" stormed Jimmie Bradshaw, pointing at the wreck. "Get orders! Are you running an engine on this line and don't know the orders for those mail bags? The orders is to move 'em! That's orders enough. Move 'em! Uncouple three of those empty box-cars and hustle 'em back. By the Great United States! any man that interferes with moving this mail will get his time, that's what he'll get. That's Doubleday, and don't you forget it. The thing is to move the mail, not to stand here chewing about it!"
