They were ominous signs—these mysterious writings left in the snow by the unknown creature that had lured a human being away from safety—and when he coupled them in his imagination with that haunting sound that broke the stillness of the dawn, a momentary dizziness shook his mind, distressing him again beyond belief. He felt the threatening aspect of it all. And, stooping down to examine the marks more closely, he caught a faint whiff of that sweet yet pungent odor that made him instantly straighten up again, fighting a sensation almost of nausea.
Then his memory played him another evil trick. He suddenly recalled those uncovered feet projecting beyond the edge of the tent, and the body's appearance of having been dragged towards the opening; the man's shrinking from something by the door when he woke later. The details now beat against his trembling mind with concerted attack. They seemed to gather in those deep spaces of the silent forest about him, where the host of trees stood waiting, listening, watching to see what he would do. The woods were closing round him.
With the persistence of true pluck, however, Simpson went forward, following the tracks as best he could, smothering these ugly emotions that sought to weaken his will. He blazed innumerable trees as he went, ever fearful of being unable to find the way back, and calling aloud at intervals of a few seconds the name of the guide. The dull tapping of the axe upon the massive trunks, and the unnatural accents of his own voice became at length sounds that he even dreaded to make, dreaded to hear. For they drew attention without ceasing to his presence and exact whereabouts, and if it were really the case that something was hunting himself down in the same way that he was hunting down another—
With a strong effort, he crushed the thought out the instant it rose. It was the beginning, he realized, of a bewilderment utterly diabolical in kind that would speedily destroy him.
Although the snow was not continuous, lying merely in shallow flurries over the more open spaces, he found no difficulty in following the tracks for the first few miles. They went straight as a ruled line wherever the trees permitted. The stride soon began to increase in length, till it finally assumed proportions that seemed absolutely impossible for any ordinary animal to have made. Like huge flying leaps they became. One of these he measured, and though he knew that "stretch" of eighteen feet must be somehow wrong, he was at a complete loss to understand why he found no signs on the snow between the extreme points. But what perplexed him even more, making him feel his vision had gone utterly awry, was that Défago's stride increased in the same manner, and finally covered the same incredible distances. It looked as if the great beast had lifted him with it and carried him across these astonishing intervals. Simpson, who was much longer in the limb, found that he could not compass even half the stretch by taking a running jump.
And the sight of these huge tracks, running side by side, silent evidence of a dreadful journey in which terror or madness had urged to impossible results, was profoundly moving. It shocked him in the secret depths of his soul. It was the most horrible thing his eyes had ever looked upon. He began to follow them mechanically, absentmindedly almost, ever peering over his shoulder to see if he, too, were being followed by something with a gigantic tread.... And soon it came about that he no longer quite realized what it was they signified—these impressions left upon the snow by something nameless and untamed, always accompanied by the footmarks of the little French Canadian, his guide, his comrade, the man who had shared his tent a few hours before, chatting, laughing, even singing by his side....
