An hour found them in the hills, plodding steadily upward, following the smoother mounds of snow which indicated heavy, secure drifts, at times progressing easily, almost swiftly, at others veering and tacking, making the precipitous ascent by digging their shoes into the snow and literally pulling themselves up, step by step. Here, where the crags rose about them, where sheer granite walls, too steep, too barren to form a resting place even for the driven snow, rose brown and gaunt above them, where the wind seemed to shriek at them from a hundred places at once, Houston dropped slowly back to watch the effect that it all was having upon the girl, to study her strength and her ability to go on. But there was no weakening in the sturdy little step, no evidence of fatigue. As they went higher, and the wind beat against them with its hail of splintered ice particles, Houston saw her heavily gloved hands go to her face in sudden pain and remain there. The man went to her side, and grasping her by the shoulder, stopped her. Then, without explanation, he brought forth a heavy bandanna handkerchief and tied it about her features, as high as possible without shutting off the sight. Her eyes thanked him. They went on. Higher--higher! the old cracks of Houston's lips, formed in his days of wandering, opened and began to bleed, the tiny, red drops falling on his clothing and congealing there. The flying ice cut his skin; he knew that his eyeballs were becoming red again, the blood-red where never a speck of white showed, only black pupils staring forth from a sea of carmine. Harder and swifter the wind swept about them; its force greater than the slight form of the woman could resist. Close went Houston to her; his arm encircled her--and she did not resist--she who, down there in the west country in the days that had gone, would have rebelled at the touch of his hand! But now they were in a strange land where personalities had vanished; two beings equipped with human intelligence and the power of locomotion, little more. All else in their natures had become subjugated to the greater tasks which faced them; the primitive had come to life; they were fighting against every vengeful weapon which an outraged Nature could hurl,--fighting at cross-purposes, he to fulfill a promise to a woman who might even now be dead, she to assuage the promptings of a merciful nature, even to the extent of the companionship of a man she had been led to revile. Afternoon came, and the welcome shelter of a ledge where the snow had drifted far outward, leaving a small space of dry rock,--to them like an island to a drifting victim of shipwreck. There they stopped, to bring food from the small provision pack which had been shifted to Medaine's shoulders, to eat silently, then, without a word, to rise and go onward.
