"Oh, forget that day on the pass, can't you?"

Johnny grunted a second time, and from his tone it was evident that he would never forget, unpleasant though the memory remained. Sensing his sullen resentment, the other tried to rally him, but made a bad job of it. The humor of men in the open is not delicate; their wit and their words become coarsened in direct proportion as they revert to the primitive; it is one effect of the solitudes.

Grant spoke extravagantly, mockingly, of his own superiority in a way which ordinarily would have brought a smile to Cantwell's lips, but the latter did not smile. He taunted Johnny humorously on his lack of physical prowess, his lack of good looks and manly qualities—something which had never failed to result in a friendly exchange of badinage; he even teased him about his defeat with the Katmai girl.

Cantwell did respond finally, but afterward he found himself wondering if Mort could have been in earnest. He dismissed the thought with some impatience. But men on the trail have too much time for their thoughts; there is nothing in the monotonous routine of the day's work to distract them, so the partner who had played out dwelt more and more upon his debt and upon his friend's easy assumption of pre-eminence. The weight of obligation began to chafe him, lightly at first, but with ever-increasing discomfort. He began to think that Grant honestly considered himself the better man, merely because chance had played into his hands.

It was silly, even childish, to dwell on the subject, he reflected, and yet he could not banish it from his mind. It was always before him, in one form or another. He felt the strength in his lean muscles, and sneered at the thought that Mort should be deceived. If it came to a physical test he felt sure he could break his slighter partner with his bare hands, and as for endurance—well, he was hungry for a chance to demonstrate it.

They talked little; men seldom converse in the wastes, for there is something about the silence of the wilderness which discourages speech. And no land is so grimly silent, so hushed and soundless, as the frozen North. For days they marched through desolation, without glimpse of human habitation, without sight of track or trail, without sound of a human voice to break the monotony. There was no game in the country, with the exception of an occasional bird or rabbit, nothing but the white hills, the fringe of alder-tops along the watercourses, and the thickets of gnarled, unhealthy spruce in the smothered valleys.

Their destination was a mysterious stream at the headwaters of the unmapped Kuskokwim, where rumor said there was gold, and whither they feared other men were hastening from the mining country far to the north.

Now it is a penalty of the White Country that men shall think of women. The open life brings health and vigor, strength and animal vitality, and these clamor for play. The cold of the still, clear days is no more biting than the fierce memories and appetites which charge through the brain at night. Passions intensify with imprisonment, recollections come to life, longings grow vivid and wild. Thoughts change to realities, the past creeps close, and dream figures are filled with blood and fire. One remembers pleasures and excesses, women's smiles, women's kisses, the invitation of outstretched arms. Wasted opportunities mock at one.

Cantwell began to brood upon the Katmai girl, for she was the last; her eyes were haunting and distance had worked its usual enchantment. He reflected that Mort had shouldered him aside and won her favor, then boasted of it. Johnny awoke one night with a dream of her, and lay quivering.

"Hell! She was only a squaw," he said, half aloud. "If I'd really tried—"
