He left the wood road, and plowed through the deep snow along the margin of the swamp, looking out for firs. But he could see nothing more than a rod or two away. The storm did not diminish, and all about him the snow seemed extraordinarily deep. He sank into it up to his knees, and sometimes it was deeper still. He walked thus a long way on the edge of the swamp woodland, not caring to plunge into the swamp until he should have spied out a balsam. At last he saw, through the cloud of snow, the tapering head of an unmistakable fir balsam. He struck into the swamp after it, parting the alder branches with the ax held with both hands before him, and sinking two or three inches deeper into the snow. The fir proved to be too irregular for a Christmas tree. Then, through the snow, he saw another farther in the swamp. He penetrated to that, and found one side of it lacking. Beyond were other firs, and he fought his way deeper and deeper into the swamp. He discovered now a circumstance that aided him somewhat in working his way through the jungle. The matted alders seemed to lean away in masses from the hummocks of earth upon which they grew, in such a way as to make crooked arched-over passageways, which, Horace thought, were curiously like the paths moles make under matted grass. He had often amused himself in summer digging out these mole-paths, and wondering why the crooked ways were constructed. These avenues through the alder thickets, away down in the bottom of a swamp quite impenetrable without them, often came to an abrupt end. Then Horace, floundering on hands and knees in the deep snow, sometimes thrusting his foot down into a watery depth, had to break his way with his ax through to another opening. He found the seclusion somewhat interesting. Down here there was no wind, and his clothing and his laborious exercise made him warm—even uncomfortably so. He lay a few minutes on his back, in a place where he could look up through an opening in the branches, and marveled at the sight of the stormy maelstrom overhead. The whirling snow looked black. For a moment the current of it seemed flowing like a river all one way; then it appeared to turn, to cross itself, and to twist about in a circle, from which it soon disentangled itself, to resume its swift and steady march in one direction. All at once it occurred to Horace to ask himself, Which direction was that? He thought first that he could not get lost in the swamp so long as he could see which way the snow was driving; but a chill ran over him when he reflected that he had not noticed, in his eagerness all the morning to be out in the storm, which way the wind was blowing. He tried now to think which way it had come as he walked to the swamp, but all he could recall was that the storm seemed to be coming from all directions at once.
