The men hastening out found their drip-tank full of ice: there was nothing for it but fresh brasses, and Glover getting down in the snow set the jack with his own hands so it should be set right. The conductor passed him a bar, but Gertrude could not see; she could only hear the ring of the frosty steel. Then with a scream the safety valve of the engine popped and the wind tossed the deafening roar in and out of the car, now half dark. Stunned by the uproar and disturbed by the failing light she left her chair, and going over sat down at the window beneath which Glover was working; some instinct made her seek him. When the car door opened, the flagman entered with both hands filled with snow. "Are you ready to start?" asked Gertrude. He shook his head and bending over a leather chair rubbed the snow vigorously between his fingers. "Oh, are you hurt?" "I froze my fingers and Mr. Glover ordered me in," said the boy. Gertrude noticed for the first time the wind and listened; standing still the car caught the full sweep and it rang in her ears softly, a far, lonely sound. While she listened the lights of the car died wholly out, but the jargon of noises from the truck kept away some of the loneliness. She knew he would soon come and when the sounds ceased she waited for him at the door and opened it hastily for him. He looked storm-beaten as he held his lantern up with a laugh. Then he examined the flagman's hand, followed Gertrude forward and placed the lantern on the table between them, his face glowing above the hooded light. They were running again, very fast, and the rapid whipping of the trucks was resonant with snow. "How far now to Medicine?" she smiled. "We are about half-way. From here to Point of Rocks we follow an Indian trail." The car was no longer warm. The darkness, too, made Gertrude restless and they searched the storage closets vainly for candles. When they sat down again they could hear the panting of the engine. The exhaust had the thinness of extreme cold. They were winding on heavy grades among the Buttes of the Castle Creek country, and when the engineer whistled for Castle station the big chime of the engine had shrunk to a baby's treble; it was growing very cold. As the car slowed, Glover caught an odor of heated oil, and going back found the coddled journal smoking again, and like an honest man cursed it heartily, then he went forward to find out what the stop was for. He came back after some moments. Gertrude was waiting at the door for him. "What did you learn?" He held his lantern up to light her face and answered her question with another. "Do you think you could stand a ride in the engine cab?" "Surely, if necessary. Why?"
