It was late in the morning. The women must have returned from the pool; yet as I drew near, I saw no sign of life whatever. “They have remained longer,” I thought; but when I was quite close to the base of the cliffs, I saw that which dashed my hopes and my happiness to earth. Strewn along the ground were a score of mute and horrible suggestions of what had taken place during my absence—bones picked clean of flesh, the bones of manlike creatures, the bones of many of the tribe of Sto-lu; nor in any cave was there sign of life. Closely I examined the ghastly remains fearful each instant that I should find the dainty skull that would shatter my happiness for life; but though I searched diligently, picking up every one of the twenty-odd skulls, I found none that was the skull of a creature but slightly removed from the ape. Hope, then, still lived. For another three days I searched north and south, east and west for the hatchetmen of Caspak; but never a trace of them did I find. It was raining most of the time now, and the weather was as near cold as it ever seems to get on Caprona. At last I gave up the search and set off toward Fort Dinosaur. For a week—a week filled with the terrors and dangers of a primeval world—I pushed on in the direction I thought was south. The sun never shone; the rain scarcely ever ceased falling. The beasts I met with were fewer in number but infinitely more terrible in temper; yet I lived on until there came to me the realization that I was hopelessly lost, that a year of sunshine would not again give me my bearings; and while I was cast down by this terrifying knowledge, the knowledge that I never again could find Lys, I stumbled upon another grave—the grave of William James, with its little crude headstone and its scrawled characters recording that he had died upon the 13th of September—killed by a saber-tooth tiger. I think that I almost gave up then. Never in my life have I felt more hopeless or helpless or alone. I was lost. I could not find my friends. I did not even know that they still lived; in fact, I could not bring myself to believe that they did. I was sure that Lys was dead. I wanted myself to die, and yet I clung to life—useless and hopeless and harrowing a thing as it had become. I clung to life because some ancient, reptilian forbear had clung to life and transmitted to me through the ages the most powerful motive that guided his minute brain—the motive of self-preservation.
