The snow grew deeper and deeper, and made the arching tops of his mole-paths lower and lower, while the labor of floundering and dragging himself through them became more terrible. Once he felt a thrill of relief upon coming on a track which he knew must be his own. He supposed that it was the track by which he had come into the jungle in the morning, strangely left uncovered by some better protection than the thicket had provided elsewhere. So he started back on it quite joyfully. And he followed it until he came to the trunk of a little maple-tree which he knew he had cut down not fifteen minutes before to clear a path.
Then he knew he was winding about and had crossed his own tracks. If he followed them farther, they would simply bring him back to where he stood now.
Meanwhile he had grown very faint—he was almost too badly scared to be aware that he was hungry.
But he felt that it must be afternoon; and on such a day, and at this time of year, the darkness would fall by half past three. He felt himself hopelessly lost—and abandoned, too, for why did not the people at the house miss him, and know that, having gone after a Christmas tree, he must be lost in the Big Swamp? Why did they not send after him?
They must come! But if he sat down and waited for them he would get chilled. Already, in spite of his efforts, he felt a numbness creeping over him. The sense of it filled him with horror. He hurled himself against the bushes; he threw himself on his hands and knees, and worked his way through the narrow passages. His mind went over and over various futile schemes for tracing his way.
All at once he stopped and pondered. If he was really going round in a ring when he thought he was going straight, could it be possible that he would go straight if he tried to go round in a ring? And if he found his way back to his track and made a ring, why not start out anew and deliberately add another ring to that? Enough circles made thus, placed side by side, would reach at last the edge of the swamp.
He went back on his tracks, and was pleased to find that the snow had not yet covered them so deeply but that he could find the place where he had branched off from the ring he had made.
Walking back on this a few steps, Horace went off to the left, purposely intending to make another circle and come back to this one. But after threading and pushing his way a long time, he convinced himself that he was not returning to it; no more tracks did he find. Did this mean that he was now following a straighter line, or merely that he was making a larger circle, and going entirely round the inner one?
A terrible fear of the snow and the earth came over him, and he could not bear to get down on his hands and knees to follow the tunnels under the bushes. But he was too weak to fight his way upright through the thicket. His brain reeled as he strained his eyes for the five-hundredth time for some sign of the trees of the woods.
It reeled still more when it seemed to him that he saw something large and black and shapeless through the gloom—some strange and threatening object descending upon him.
