He might have glided down that slope for seconds, or minutes, or even hours, for all that he knew of the passage of time. He seemed to be moving with great speed, and yet, in breathless anticipation of the inevitable plunge that, in fancy, he felt himself to be taking with each instant, his downward flight seemed indefinitely prolonged.
At length the suspense was ended. Almost with the quickness of thought the boy passed into a region of dazzling sunlight, was launched into space, and found himself sinking down, down, down, as though he would never stop, in water so cold that its chill pierced him like knives, and compressed his head as with a band of iron.
Looking up through the crystal sheet, he could see an apparently endless line of bubbles rising from where he was to the surface, and, after a while, he began to follow them. With a breathless gasp he again reached the blessed air, and, dashing the water from his eyes, began to consider his situation. He was dazed and bewildered at finding himself still alive and apparently none the worse for his tremendous slide. Although he was in bright sunlight, the mountain-side down which he had come was hidden beneath dense folds of cloud, out of which he seemed to have dropped.
Gently paddling with his hands, just enough to keep himself afloat, Glen looked anxiously about for some beach or other place at which he might effect a landing, but could discover none. The upper edge of the snow-field, that bounded the lake on one side, projected far over the water, so that, while he might swim under it, there was no possibility of getting on it. On all other sides sheer walls of rock rose from the water, without a trace of beach, or even of boulders, at their base.
In all this solid wall there was but one break. Not far from where Glen swam, and just beyond the snow-field, a narrow cleft appeared; and from it came an indistinct roar of waters. Glen felt himself growing numbed and powerless. He must either give up at once, and tamely allow himself to sink where he was, or he must swim to that cleft, and take his chances of getting out through it. He fully expected to find a waterfall just beyond the gloomy portal, and he clearly realized what his fate would be if it were there. But whatever he did must be done quickly. He knew that, and began to swim towards the cleft.
As he approached it, he felt himself impelled onward by a gentle current that grew stronger with each moment. Now he could not go back if he would. He passed between two lofty walls of rock, and, instead of dashing over a waterfall, was borne along by a swift, smooth torrent that looked black as ink in the gloom of its mysterious channel.
Ere the swimmer had traversed more than fifty yards of this dim waterway, the channel turned sharply to the left, and the character of the lower portion of its wall, on that side, changed from a precipice to a slope. In another moment Glen's feet touched bottom, and he was slowly dragging his numbed and exhausted body ashore.
Although the sun was still shining on the mountain-side, far above him, it was already twilight where he was, and he had no desire to explore that stream farther in darkness. It would be bad enough by daylight. In fact, he was so thankful to escape from that icy water that, had the light been increasing instead of waning at that moment, he would probably have lingered long on those blessed rocks before tempting it further.
Now, as he gazed about him in search of some place in which, or on which, to pass the long hours of darkness, his eye fell on a confused pile of driftwood not far away. Here was a prize indeed. He had matches, and, thanks to "Billy" Brackett, they were still dry. Now he could have a fire. He found the driftwood to be a mass of branches and tree-trunks, bleached to the whiteness of bones, and evidently brought down by some much higher water than the present. They were lodged in the mouth of a deep water-worn hollow in the rock, and converted a certain portion of it into a sort of a cave. Creeping in behind this wooden wall of gnarled roots, twisted branches, and splintered trunks, the shivering boy felt for his hatchet; but it had disappeared. His knife still remained in its sheath, however, and with it he finally managed, though with great difficulty on account of the numbness of his hands, to cut off a little pile of slivers and shavings from a bit of pine.
In another moment the cave was illumined with a bright glow from one of his precious matches, and a tiny flame was creeping up through the handful of kindling. With careful nursing and judicious feeding the little flame rapidly increased in strength and brightness, until it was lighting the whole place with its cheerful glow, and was leaping, with many cracklings, through the entire mass of driftwood.
