"All right!" answers one of the men, and handling their guns, the two disappear to take part in the trouble with the express agent, which is now creating a great commotion on the train, the passengers in Lawrence's Pullman crying out: "Road agents!" and the young lady in Miss Travenion's car, who has been awakened by the noise, screaming for help. This excitement aids Lawrence. He steps into the car, and touching his sweetheart on the shoulder, whispers: "Come!" And she following him to the platform, he springs into the snow-drift, and says: "I must carry you!" "Certainly!" Her arms clasp themselves trustingly round his neck, as he trudges through the snow, bearing his happiness with him. The locomotive on the Y is just moving as he reaches it, for he crosses directly to it, not daring to carry her past Kruger and his men, who are still about Wells, Fargo & Co.'s car. "Ah, you're going to carry me away on the locomotive!" whispers Erma, as Lawrence puts her on board. "Yes, we'll take care of you!" mutters the engineer, giving Harry a helping hand. In another moment they are in the cab of the locomotive, which is slowly running over the Y towards the main track, which leads to the East, and safety. This has been kept open as far as the snow-shed, and they will probably not meet a great deal of drift until they get beyond it, but the steam is light in the engine, and it cannot move very fast. The other locomotive stands behind them, on the Y. Lawrence notices, as they leave it, that its fires are banked, and some one is on board it, though apparently asleep. A second after, they pass Mr. Buck Powers, who switches them to the main track, they running so slowly that he easily follows them, and jumps on board. All this time Harry has both ears and eyes fixed on the forward end of the train, to see if their absence is discovered. But the Wells, Fargo & Co.'s man is still standing the Mormons and their bishop off, and threatening to shoot; and his movements interest them so much they do not notice the great mass of iron that has come on to the main track, and is now plunging away from them down the incline towards the long snow-shed. "Now," Harry says to the engineer, giving a sigh of relief, "you can light your headlight." Just then a cry comes out from behind them. It is that of the conductor of the train, who is screaming: "Great Scott! who's run away with the locomotive?" and some of Kruger's men run shouting through the snow. Then Lawrence cries, "Give her steam!" The locomotive dashes through little drifts, and drowns sound, but he knows that in a very few moments Lot Kruger will have discovered that what he values more than the stock of the Utah Central Railway is passing away from him. The engine is already flying through the snow-shed--one of the two long ones that line the steep decline leading towards Piedmont and the East.
