Of them all, only Houston, tired even as they were tired, yet with something that they had forgotten, a brain, remained open-eyed. What had become of Medaine? Had she recovered? Had she too gone to Tollifer, perhaps on a later trip of the plow? The thoughts ran through his head like the repetition of some weird refrain. He sought sleep in vain. From far away came the whistles of locomotives, answering the signals of the snowplows ahead. Outside some one shouted, as though calling to him; again he remembered the bulky cars of machinery at Tollifer. It was partially, at least, his battle they were fighting out there, while he remained inactive. He rose and sought the door, fumbling aimlessly in his pockets for his gloves. Something tinkled on the floor as he brought them forth, and he bent to pick up the little crucifix with its twisted, tangled chain, forgotten at Tollifer. Dully, hazily, he stared at it with his red eyes, with the faint feeling of a duty neglected. Then: "She only said they might want it," he mumbled. "I'm sorry--I should have remembered. I'm always failing--at something." Then, dully anxious to do his part, to take his place in the fighting line, he replaced the tiny bit of gold in his pocket, and threading his way through the circuitous tunnel of snow, stepped forth into the night. It was one of those brief spaces of starlight between storms, and the crews were making the most of it. The wind had ceased temporarily, allowing every possible workman to be pulled from the ordinary task of keeping the tracks clear of the "pick-ups" of the wind, blowing the snow down from the drifts of the hill, and to be concentrated upon the primary task of many,--the clearing of the packed sittings which filled the first snowshed. Atop the oblong shed, swept clear by the wind, a light was signalling, telling the progress of the plow, and its consequent engines, within. Even from the distance, Barry could hear the surge of the terrific impact, as the rotary, pushed by the four tremendous "compounds" and Malletts which formed its additional motive power, smashed against the tight-jammed contents of the shed, snarled and tore at its enemy, then, beaten at last by the crusted ice of the rails, came grudgingly back, that the ice crews, with their axes and bars, might break the crystallization from the rails and give traction for another assault. Houston started forward, only to stop. A figure in the dim light of the cook car had caught his eye. Medaine Robinette.
