"So! I talk too much," Grant thought. The accusation struck in his mind and he determined to speak no more.
"He blames me," Cantwell reflected, bitterly. "I'm in wrong again and he couldn't keep his mouth shut. A hell of a partner, he is!"
All day they plodded on, neither trusting himself to speak. They ate their evening meal like mutes; they avoided each other's eyes. Even the guide noticed the change and looked on curiously.
There were two robes and these the partners shared nightly, but their hatred had grown so during the past few hours that the thought of lying side by side, limb to limb, was distasteful. Yet neither dared suggest a division of the bedding, for that would have brought further words and resulted in the crash which they longed for, but feared. They stripped off their furs, and lay down beside each other with the same repugnance they would have felt had there been a serpent in the couch.
This unending malevolent silence became terrible. The strain of it increased, for each man now had something definite to cherish in the words and the looks that had passed. They divided the camp work with scrupulous nicety, each man waited upon himself and asked no favors. The knowledge of his debt forever chafed Cantwell; Grant resented his companion's lack of gratitude.
Of course they spoke occasionally—it was beyond human endurance to remain entirely dumb—but they conversed in monosyllables, about trivial things, and their voices were throaty, as if the effort choked them. Meanwhile they continued to glow inwardly at a white heat.
Cantwell no longer felt the desire to merely match his strength against Grant's; the estrangement had become too wide for that; a physical victory would have been flat and tasteless; he craved some deeper satisfaction. He began to think of the ax—just how or when or why he never knew. It was a thin-bladed, polished thing of frosty steel, and the more he thought of it the stronger grew his impulse to rid himself once for all of that presence which exasperated him. It would be very easy, he reasoned; a sudden blow, with the weight of his shoulders behind it—he fancied he could feel the bit sink into Grant's flesh, cleaving bone and cartilages in its course—a slanting downward stroke, aimed at the neck where it joined the body, and he would be forever satisfied. It would be ridiculously simple. He practised in the gloom of evening as he felled spruce-trees for fire-wood; he guarded the ax religiously; it became a living thing which urged him on to violence. He saw it standing by the tent-fly when he closed his eyes to sleep; he dreamed of it; he sought it out with his eyes when he first awoke. He slid it loosely under the sled lashings every morning, thinking that its use could not long be delayed.
As for Grant, the carbine dwelt forever in his mind, and his fingers itched for it. He secretly slipped a cartridge into the chamber, and when an occasional ptarmigan offered itself for a target he saw the white spot on the breast of Johnny's reindeer parka, dancing ahead of the Lyman bead.
The solitude had done its work; the North had played its grim comedy to the final curtain, making sport of men's affections and turning love to rankling hate. But into the mind of each man crept a certain craftiness. Each longed to strike, but feared to face the consequences. It was lonesome, here among the white hills and the deathly silences, yet they reflected that it would be still more lonesome if they were left to keep step with nothing more substantial than a memory. They determined, therefore, to wait until civilization was nearer, meanwhile rehearsing the moment they knew was inevitable. Over and over in their thoughts each of them enacted the scene, ending it always with the picture of a prostrate man in a patch of trampled snow which grew crimson as the other gloated.
They paused at Bethel Mission long enough to load with dried salmon, then made the ninety-mile portage over lake and tundra to the Yukon. There they got their first touch of the "inside" world. They camped in a barabara where white men had slept a few nights before, and heard their own language spoken by native tongues. The time was growing short now, and they purposely dismissed their guide, knowing that the trail was plain from there on. When they hitched up, on the next morning, Cantwell placed the ax, bit down, between the tarpaulin and the sled rail, leaving the helve projecting where his hand could reach it. Grant thrust the barrel of the rifle beneath a lashing, with the butt close by the handle-bars, and it was loaded.
