"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.
