The trouble with him was that he was without imagination. He was quick and alert in the things of life, but only in the things, and not in the significances. Fifty degrees below zero meant eighty-odd degrees of frost. Such fact impressed him as being cold and uncomfortable, and that was all. It did not lead him to meditate upon his frailty as a creature of temperature, and upon man's frailty in general, able only to live within certain narrow limits of heat and cold; and from there on it did not lead him to the conjectural field of immortality and man's place in the universe.

"They sat on through the passing glory of the day, talking as lovers are prone to talk, marvelling at the wonder of love and at destiny that had flung them so strangely together, and dogmatically believing that they loved to a degree never attained by lovers before. And they returned insistently, again and again, to a rehearsal of their first impressions of each other and to hopeless attempts to analyze just precisely what they felt for each other and how much there was of it. The cloud–masses on the western horizon received the descending sun, and the circle of the sky turned to rose, while the zenith glowed with the same warm color. The rosy light was all about them, flooding over them, as she sang, "Good–by, Sweet Day." She sang softly, leaning in the cradle of his arm, her hands in his, their hearts in each other's hands."

He became quicker of movement than the other dogs, swifter of foot, craftier, deadlier, more lithe, more lean with ironlike muscle and sinew, more enduring, more cruel more ferocious, and more intelligent. He had to become all these things, else he would not have held his own nor survived the hostile environment in which he found himself.

I am that man, the sum of him, the all of him, the hairless biped who struggled upward from the slime and created love and law out of the anarchy of fecund life that screamed and squalled in the jungle. I am all that that man was and did become. I see myself, through the painful generations, snaring and killing the game and the fish, clearing the first fields from the forest, making rude tools of stone and bone, building houses of wood, thatching the roofs with leaves and straw, domesticating the wild grasses and meadow roots, fathering them to become the progenitors of rice and millet and wheat and barley and all manner of succulent edibles, learning to scratch the soil, to sow, to reap, to store, beating out the fibers of plants to spin into thread and to weave into cloth, devising systems of irrigation, working in metals, making markets and trade routes, building boats, and founding navigation — ay, and organizing village life, welding villages to villages till they became tribes, welding tribes together till they became nations, ever seeking the laws of things, ever making the laws of humans so that humans might live together in amity and by united effort beat down and destroy all manner of creeping, crawling, squalling things that might else destroy them.

He had a way of taking Buck's head roughly between his hands, and resting his own head upon Buck's, of shaking him back and forth, the while calling him ill names that to Buck were love names. Buck knew no greater joy than that rough embrace and the sound of murmured oaths, and at each jerk back and forth it seemed that his heart would be shaken out of his body so great was its ecstasy.

Always has woman crouched close to earth like a partridge hen mothering her young; always has my wantonness of roving led me out on the shining ways; and always have my star paths returned me to her, the figure everlasting, the woman, the one woman, for whose arms I had such need that clasped in them I have forgotten the stars.

For her I accomplished Odysseys scaled mountains crossed deserts; for her I led the hunt and was forward in battle; and for her end' to her I sang my songs of the things I had done. All ecstasies of life and rhapsodies of delight have been mine because of her. And here, at the end, I can say that I have known no sweeter, deeper madness of being than to drown in the fragrant glory and forgetfulness of her hair.

When a man journeys into a far country, he must be prepared to forget many of the things he has learned, and to acquire such customs as are inherent with existence in the new land; he must abandon the old ideals and the old gods, and oftentimes he must reverse the very codes by which his conduct has hitherto been shaped.

He was disappointed in it all. He had developed into an alien. As the steam beer had tasted raw, so their companionship seemed raw to him. He was too far removed. Too many thousands of opened books yawned between them and him. He had exiled himself. He had travelled in the vast realm of intellect until he could no longer return home. On the other hand, he was human, and his gregarious need for companionship remained unsatisfied. He had found no new home.

He pleaded with his eyes to remain there. The driver was perplexed. His comrades talked of how a dog could break its heart through being denied the work that killed it, and recalled instances they had known, where dogs, too old for the toil, or injured, had died because they were cut out of the traces. Also, they held it a mercy, since Dave was to die anyway, that he should die in the traces, heart-easy and content. So he was harnessed in again, and proudly he pulled as of old, though more than once he cried out involuntarily from the bite of his inward hurt. Several times he fell down and was dragged in the traces, and once the sled ran upon him so that he limped thereafter in one of his hind legs.
