"_Show you how a Chicago railroad man treats chumps!_" And though Erma cries: "Don't! You risk your life!" and Lawrence puts out a detaining hand, even as they come to the Piedmont side-track, the boy jumps from the cab, unlocks the switch, and hides himself in the snow-drift. "My God! He's going to run 'em off the track! My pard's the boss of that locomotive!" screams the engineer. "He'll be smashed to pieces!" "Go on!" answers Lawrence, and his pistol again threatens. The locomotive dashes forward, for there is a roar two hundred yards behind them, and over the noise they hear Kruger's yell of triumph, which, even as he utters it, is turned into a howl of rage. There is a shriek of terror from the engineer of the pursuing locomotive, for Buck Powers, in the moonlight, has risen up beside the switch, and turned it, just as the engine dashes to it, not so as to side-track it, but only half way, to dash it over ties and snow-drifts to destruction. As the locomotive passes, Kruger, who has his pistol in his hand, turns it from the direction of Lawrence and the flying locomotive straight at the breast of the boy at the switch, and fires upon him! And Buck Powers, giving a shriek, staggers and falls into a snow-bank, reddening it with his blood. But even as Buck does so, he is avenged. The locomotive, plunging forward off the track into the drifting snow, topples over, and though the engineer and fireman jump free, Kruger, with his eye in grim triumph on the dying boy, is thrown beneath the ponderous mass of iron, that topples over him, crushing his body, and sending his soul to where the souls of the Danites go. The engineer and fireman clamber out of the snow-drift unharmed, though shaken up. Three of the Mormon _posse_ who have been with Kruger come out of the snow unarmed, for their Winchesters are buried deep in a white bank; and Lawrence, knowing they are helpless, makes the engineer run his locomotive back to the switch. Springing out, he has the boy in his arms in a minute, and getting into the cab, he holds Buck Powers to his breast, while his locomotive goes on its way unhindered now, though followed by the curses of its Mormon pursuers. Then Erma whispers to Harry, "What chance?" But he shakes his head, for he knows what those gray-blue lips mean--he has seen them too often on battlefields. As he does so, the boy, whose face has already grown pallid, and upon whose forehead the dew of death is standing, gasps: "I saved ye, Miss Beauty!--Didn't I do the trick like--like a Chicago railroad man?" "Yes," sobs the girl, bending over him. "What can I do for you?" "The Cap won't be jealous--just give me one kiss--that's all. I've never been kissed--by--a--beautiful--young lady." And two sweet lips come to his, that are already cold, and he gasps: "You're pretty as a Chicago girl--that's where I'm goin'!"
