Then with his snowshoes and his pack of death, he went out the door, to plunge through another drift, to force his way into a cabin, and there, a plodding, dumb figure, go soddenly about the duties of comfort. And more than once in the howling, blustery night which followed, Houston shivered, shook himself into action and rose to rebuild a fire that had died while he had sat hunched in the hard, uncomfortable chair beside it, trying to fathom what the day had meant, striving to hope for the keeping of the promises that an hysterical woman had made, struggling for the strength to go on,--on with this cheery, brave little bit of humanity in the next cabin, without a word in self-extenuation, without a hint to break the lack of estimation in which she held him, without a plea in his own defense. And some way, Houston felt that such a plea now would be cheap and tawdry; they were in a world where there were bigger things than human aims and human frailties. Besides, he had locked his lips at the command of a grief-ridden woman. To open them in self-extenuation would mean that she must be brought into it; for she had been the one who had clinched the points of suspicion in the mind of Medaine Robinette. Were he now to speak of proof that she had lied-- It was impossible. The wind-swept night became wind-swept dawn, to find him still huddled there, still thinking, still grim and drawn and haggard with sleeplessness and fatigue. Then he rose at a call from without: "Are you ready?" He affixed the pack. Together they went on again, graceless figures in frozen clothing, she pointing the way, he aiding her with his strength, in the final battle toward the summit of the range,--and Crestline. Hours they plodded and climbed, climbed and plodded, the blood again dripping from his lips, her features again shielded by the heavy folds of the bandanna; the moisture of their breath at times swirling about them like angry steam, at others invisible in the areas of sudden dryness, where the atmosphere lapped up even the vapors of laboring lungs before it could visualize. Snow and cloud and rising walls of granite: this was their world, and they crawling pigmies within it. Once she brushed against the pack on his back and drew away with a sudden recoil. Houston dully realized the reason. The selfish, gripping hands of Winter, holding nothing sacred, had invaded even there. Noon. And a half-cry from both of them, a burst of energy which soon faded. For above was Crestline--even as the little Croatian settlement had been--smokeless, lifeless. They had gone from here also, hurrying humans fleeing with the last snowplow before the tempest, beings afraid to remain, once the lines of communication were broken. But there was nothing to do but go on.
