There were embers still alive where was a spot of red at one end of the cave, and I cast down my load and threw on fresh wood, which was at hand, and then lay down to sleep, for I was tired. But I could not sleep. There were flames and light in the cave and, now, everything came back to me. I remembered the two days before I went away with my companions. I remembered the pleasures and perils of my life, and all the horrors of the discovery, not long ago, when I, returning from a night spent with a hunter in another cave, found all of those I had lived with dead and nearly all devoured, all slain in the cave together, surprised while sleeping, by the wolf pack which had found swift entrance through the opening, for once left carelessly unblocked by slabs of stone. Then, all at once, with my clearing mind came to me the thought that I was not a solitary creature inhabiting that cave. I ran to its mouth and my “O-o-e-e” went forth resoundingly. Again and again I called, and at last there was an answer, nearer and nearer with each reply, and a man came running easily. I was glad. It was Woof, my hunting mate, who lived with me in the cave. A great companion was Woof. He had left his own people to come and live with me, for we had known each other a long time. He was almost as tall and strong as I and could run almost as swiftly as the little deer. He loped up the pathway to our home, saw the meat, and shouted aloud in satisfaction and began to roast and eat. He had not been over-fortunate in his hunting in my absence. We talked long in our clucking way until the day was late. Then we heaped up the stone slabs until the entrance to the cave was filled nearly to the top and threw ourselves down to sleep. As my eyes grew heavy I dreamed again perplexedly. Again I was in the treetops, swinging easily along and hearing familiar cries. And there were flames and roaring and tottering forests. I would waken at times and look upon the smouldering fire and toward where Woof lay breathing deeply, and realize the present, and then a fog would arise and Woof and the cave side would disappear. Had there been something before? I could see, at times, a face, but to whom it belonged I could not tell. I knew it now; it was a face of another time, the merry, impish face of an ape-like creature with whom I had had comradeship. I awakened and groped hungrily in my mind, but could remember nothing. At last I slept contentedly. With the flood of the fair morning light came still greater clearness to my thoughts. I forgot for a time even that I had dreamed and was, like Woof, eager for the outside. It was a good thing that there was yet meat enough to finish in a great breakfast. As things went we were well-to-do young men. Club in hand, we tumbled down the pathway and swung up the long ravine.
