As the day wore along he came into valleys or swales where game was more plentiful. A band of caribou passed by, twenty and odd animals, tantalizingly within rifle range. He felt a wild desire to run after them, a certitude that he could run them down. A black fox came toward him, carrying a ptarmigan in his mouth. The man shouted. It was a fearful cry, but the fox, leaping away in fright, did not drop the ptarmigan. Late in the afternoon he followed a stream, milky with lime, which ran through sparse patches of rush-grass. Grasping these rushes firmly near the root, he pulled up what resembled a young onion-sprout no larger than a shingle-nail. It was tender, and his teeth sank into it with a crunch that promised deliciously of food. But its fibers were tough. It was composed of stringy filaments saturated with water, like the berries, and devoid of nourishment. He threw off his pack and went into the rush-grass on hands and knees, crunching and munching, like some bovine creature. He was very weary and often wished to rest--to lie down and sleep; but he was continually driven on--not so much by his desire to gain the land of little sticks as by his hunger. He searched little ponds for frogs and dug up the earth with his nails for worms, though he knew in spite that neither frogs nor worms existed so far north. He looked into every pool of water vainly, until, as the long twilight came on, he discovered a solitary fish, the size of a minnow, in such a pool. He plunged his arm in up to the shoulder, but it eluded him. He reached for it with both hands and stirred up the milky mud at the bottom. In his excitement he fell in, wetting himself to the waist. Then the water was too muddy to admit of his seeing the fish, and he was compelled to wait until the sediment had settled. The pursuit was renewed, till the water was again muddied. But he could not wait. He unstrapped the tin bucket and began to bale the pool. He baled wildly at first, splashing himself and flinging the water so short a distance that it ran back into the pool. He worked more carefully, striving to be cool, though his heart was pounding against his chest and his hands were trembling. At the end of half an hour the pool was nearly dry. Not a cupful of water remained. And there was no fish. He found a hidden crevice among the stones through which it had escaped to the adjoining and larger pool--a pool which he could not empty in a night and a day. Had he known of the crevice, he could have closed it with a rock at the beginning and the fish would have been his. Thus he thought, and crumpled up and sank down upon the wet earth. At first he cried softly to himself, then he cried loudly to the pitiless desolation that ringed him around; and for a long time after he was shaken by great dry sobs.
