The moon that night was too young to shed much light. But just after Jean and Jake sleepily laid aside their pipes and closed their eyes, the aurora borealis flamed out icily in a clear sky, bringing more than all the light Bill needed. In that frozen stillness Bill's brain was like the interior of a lighted factory with all its machinery in full swing. Fed by hate and slowly accumulated stores of bitter anger, his thoughts went throbbing in and out the lighted convolutions of his brain with the silent positive efficiency of a gas-engine's pistons.
Bill understood everything in the world that night in his own world, and he overlooked nothing. He would have given much, very much, to have been able to remove Jean's camp a mile or so away. The belt of open snow-space between it and him was all too narrow for his liking. Well he knew how swiftly Jean could move, how certainly he could strike when the need arose. But for this Bill had done murder that night, as surely as ever softly treading human desperado in the dead of night has done murder at a bedside. As it was he thought he must fight. Well, he was prepared. Nay, his bowels yearned for it just as strongly as any dog's bowels had yearned for fresh-killed meat that night. More strongly, for in him the one yearning had mastered and ridden down the other yearning, thus giving him his perfect preparation.
The full-fed team-dogs had been too idle that night to dig out proper sleeping-nests for themselves in the snow. A mere circling whisp of head and tail and feet had served them, and the upper half of Jan's magnificent frame lay fully exposed halfway down the slope from Bill's tree. Very deliberately now Bill rose, and moved toward Jan, walking with dainty, springy steps like a cat at play. In all that countryside Bill possessed an absolute monopoly of springiness and elasticity. But, at their most sluggish, dogs in the northland are, of course, more alert than the home-staying dogs of civilization. Snip snarled fatly as Bill passed with his catlike tread. Jan, the crimson haw of one eye gleaming as its lid lifted, growled savagely but low as Bill approached him. His big limbs twitched convulsively and the hair about his shoulders stiffened; but so grossly full-fed was he that he did not rise, though the note of his growl ascended toward that of a snarl as Bill came nearer.
Here again, and for the hundredth time that night, Bill's icy self-control, his really marvelous command of his impulses, was sorely tried. His enemy actually was recumbent in the snow before him, while he, taut as a strung bow, was most exquisitely poised for the attack. Why fight? Why not swift delicious murder, and the gush of the loathed one's throat-blood between his fangs? Bill knew well why it must not be. But given the knowledge, how many dogs in his case, nay, how many men similarly tempted, could have forced discretion to master impulse?
Attempted murder must mean furious uproar, and uproar must mean attempted rescue; and attempted rescue, so close to camp, might well rob Bill of the life he claimed. It might leave Jan alive and himself clubbed into insensibility. In the fire-lighted brain of Bill was understanding of all things, and the determination to take no chances with regard to this the greatest killing of his life.
And so, with the most delicate care, the most minutely measured instalments of provocation, he proceeded to "crowd" the infinitely sluggish Jan. So sunk in sloth was Jan that he, who three hours earlier had been pricked to fury by an insolent glance from Bill's eyes, now positively submitted to the actual touch of Bill's nose on his hocks before he would budge. And then with a long snarl he only edged himself a yard or two away.
"Be still, be still! For God's sake give peace!" his heavy movements seemed to say.
Peace! And in Bill's lighted brain the roar of furnaces and the remorseless whirl of swiftly driven machinery!
With the fathomless scorn of the self-mastering ascetic for the sodden debauchee, Bill proceeded coldly with his task of "crowding" Jan out and away from the safety of that place and into the wilderness. In a few minutes he ventured to hasten matters by actually nipping one of Jan's hind legs with his teeth. But with what precise delicacy! It had been sweet to drive the fangs home and feel the bone and sinew crack. But that would not mean death and might bring rescue. So Bill's jaws pressed no more hardly than those of a nursing-mother of his kind what time she draws a too venturesome pup into the shelter of her warm dugs.
It was beautifully done; a triumph of self-mastery and an exquisitely gauged piece of tactics. It brought Jan quickly lumbering to his feet, snarling savagely but not very loudly. It sent him sullenly some twenty, thirty paces nearer to his doom and farther from the camp. A dozen paces Bill followed him, crowding threateningly to enforce the right direction. And then Bill halted, not wishing to risk causing Jan to dodge and double backward toward the camp. And because his persecutor stopped when he did, Jan followed the line of least resistance, lumbering on down the slope into the deep wood for twenty paces more before lowering himself again with a grunt for the repose which, to his glutted sloth, seemed more desirable now than all the meat in the world, aye, and of more pressing import than all his dignity, than all his new pride in working efficiency in his leadership.
