There was about ten inches of snow on the flat, with deep encumbering drifts in the hollows; and his advance was very slow. The ill-nourished horse wearied immediately; and any pace beyond a walk was out of the question. Had Garth only possessed snow-shoes he could have made much better time on foot. The vast expanse was as empty as a clean sheet of paper; nevertheless, he saw the prairie was not without its busy population, as evidenced by the number of tracks of little furry paws that had crossed his course already since the snow finished falling.
At noon, having made about eleven miles (he figured), he came to the brink of a coulée wider and deeper than any they had crossed hitherto; and which contained a stream in the bottom, running blackly around snow-capped stones. As he refreshed himself, and allowed his horse to drink, he reflected that Grylls would have reached this stream the day before about the time the snow commenced; and that it was likely the outfit had camped on its bank until the storm passed. He determined to search up and down before pushing ahead.
Sure enough, no more than two hundred yards down-stream he began to come upon the tracks of horses and saw the bare patches they had pawed to reach the grass; and a little farther he ran plump upon the fresh remains of the camp; two bare spots where tents had been pitched, the ashes of a fire, and innumerable tracks of men and horses—the whole startlingly conspicuous in the sweep of unbroken snow.
Garth's heart swelled with rage and mortification to think what a little distance had separated them during the night; and how by rising only three hours earlier, he might perhaps have caught them. But presently cooler counsels came to his aid; and when he considered the well-beaten track that led over the hill beyond, he was thankful for so much luck. He knew that at least until more snow should fall, they could never shake him off again; and he rode after with a renewed courage. His horse, too, freed of the entangling drifts, and sensing the other horses ahead, seemed to overcome his weakness for a while; and loped over the beaten trail with a good will.
Beyond this coulée the character of the country began to change. Crossing a height, Garth saw a range of gleaming mountains off to the west at no great distance; his course was heading him obliquely into the foothills. The prairie gradually broke up; the mounds became hills; and the hollows deepened into valleys. With every mile, almost, the hills became higher and more conical; outcroppings of rock began to appear; and the little streams ran in gorges now, instead of coulées.
In the rougher country the horse's access of courage soon failed. His wind was gone, he sobbed for breath; and Garth was presently reduced to the necessity of leading him up every incline. On a wide flat between two ranges, he mounted after a long walk, and urged him into a run over this easy piece. The slack-twisted animal was not equal to the effort; halfway across, his heart broke; and he collapsed in a heap, ploughing up the snow, and flinging his rider over his head. When Garth returned to him, he was stone dead. In the midst of his chagrin the man could spare a glance of pity for the shaggy, misshapen beast. One of the vulgar equine tribe, at his best neither beautiful nor courageous, he had nevertheless given his life to the journey.
Beside the stony watercourse that traversed this little plain, he made a cache of saddle, bridle and what food he could not carry on his back. Over the spot he piled a cairn of stones to mark it, and protect the little store from marauding animals. In addition to blankets, rifle and ammunition, he carried with him food sufficient for about five days. In an hour he was on his way again.
During the rest of the day, and the following day, the character of the country changed only in degree. The trail never carried him directly into the mountains, but skirted among the foothills, which raised strange, abrupt, detached cones on either hand—steep, naked, unreasonable shapes of earth, like nightmare forms. Each day Garth plodded to the limit of his strength, reckless of what lay before him, regarding only the beaten trail which led the way. From various signs it was clear those ahead ever gained on him; but he kept himself up with the thought that they must sooner or later make an extended stop to recuperate their horses. Each night he made his tea with snow-water; and, rolling up in his blankets beside the fire, slept under the stars; and at dawn he was astir again. Hard work was his beneficent sedative.
On the second night as he lay down he heard, or fancied he heard in the stillness, the breath of a far-off, heavy sound. He ascribed it to the roar of the great falls Rina had told him of; and the thought lent new vigour to his limbs next morning. He had another reason to hurry his steps; for each day had waxed a little warmer; and to-day the snow melted fast, threatening at last to obliterate the track he followed.
In the afternoon the going became harder, for the mountains reached down long spurs athwart his path, over which he had to toil. Like the conical hills they were bare of all timber; only the valleys and gulches were wooded. On the first of these ascents, burdened as he was, over-exertion and insufficient sleep began to tell on Garth; and he became conscious, for the first, of a terrible weariness in his back. He crushed it down; he could not fail; he had to keep on. But the next ascent was harder still; and the shape of fear grew in his breast.
