When the man had finished, he filled his pipe and took his comfortable time over a smoke. Then he pulled on his mittens, settled the ear-flaps of his cap firmly about his ears, and took the creek trail up the left fork. The dog was disappointed and yearned back toward the fire. This man did not know cold. Possibly all the generations of his ancestry had been ignorant of cold, of real cold, of cold one hundred and seven degrees below freezing-point. But the dog knew; all its ancestry knew, and it had inherited the knowledge. And it knew that it was not good to walk abroad in such fearful cold. It was the time to lie snug in a hole in the snow and wait for a curtain of cloud to be drawn across the face of outer space whence this cold came. On the other hand, there was keen intimacy between the dog and the man. The one was the toil-slave of the other, and the only caresses it had ever received were the caresses of the whip-lash and of harsh and menacing throat-sounds that threatened the whip-lash. So the dog made no effort to communicate its apprehension to the man. It was not concerned in the welfare of the man; it was for its own sake that it yearned back toward the fire. But the man whistled, and spoke to it with the sound of whip-lashes, and the dog swung in at the man’s heels and followed after.

The man took a chew of tobacco and proceeded to start a new amber beard. Also, his moist breath quickly powdered with white his moustache, eyebrows, and lashes. There did not seem to be so many springs on the left fork of the Henderson, and for half an hour the man saw no signs of any. And then it happened. At a place where there were no signs, where the soft, unbroken snow seemed to advertise solidity beneath, the man broke through. It was not deep. He wetted himself half-way to the knees before he floundered out to the firm crust.

He was angry, and cursed his luck aloud. He had hoped to get into camp with the boys at six o’clock, and this would delay him an hour, for he would have to build a fire and dry out his foot-gear. This was imperative at that low temperature-he knew that much; and he turned aside to the bank, which he climbed. On top, tangled in the underbrush about the trunks of several small spruce trees, was a high-water deposit of dry firewood-sticks and twigs principally, but also larger portions of seasoned branches and fine, dry, last-year’s grasses. He threw down several large pieces on top of the snow. This served for a foundation and prevented the young flame from drowning itself in the snow it otherwise would melt. The flame he got by touching a match to a small shred of birch-bark that he took from his pocket. This burned even more readily than paper. Placing it on the foundation, he fed the young flame with wisps of dry grass and with the tiniest d
