on even more rapidly than before, because I now knew that I was upon the right trail and that up to this point at least, Lys still had lived.
I made over twenty miles that day, for I was now hardened to fatigue and accustomed to long-distance walking, having spent considerable time hunting and exploring in the immediate vicinity of camp. A dozen times that day was my life threatened by fearsome creatures of the earth or sky, though I could not but note that the farther north I traveled, the fewer were the great dinosaurs, though they still persisted in lesser numbers. On the other. hand, the quantity of ruminants and the variety and frequency of carnivorous animals increased. Each square mile of Caspak harbored its terrors.
At intervals along the way I found bits of muslin, and often they reassured me when otherwise I should have been doubtful of the trail to take where two crossed or where there were forks, as occurred at several points. And so, as night was drawing on, I came to the southern end of a line of cliffs loftier than any I had seen before, and as I approached them, there was wafted to my nostrils the pungent aroma of wood-smoke. What could it mean? There could, to my mind, be but a single solution: man abided close by, a higher order of man than we had as yet seen, other than Ahm, the Neanderthal man. I wondered again as I had so many times that day if it had not been Ahm who stole Lys.
Cautiously I approached the flank of the cliffs, where they terminated in an abrupt escarpment as though some all powerful hand had broken off a great section of rock and set it upon the surface of the earth. It was now quite dark, and as I crept around the edge of the cliff, I saw at a little distance a great fire around which were many figures—apparently human figures. Cautioning Nobs to silence, and he had learned many lessons in the value of obedience since we had entered Caspak, I slunk forward, taking advantage of whatever cover I could find, until from behind a bush I could distinctly see the creatures assembled by the fire. They were human and yet not human. I should say that they were a little higher in the scale of evolution than Ahm, possibly occupying a plane of evolution between that of the Neanderthal man and what is known as the Grimaldi race. Their features were distinctly negroid, though their skins were white. A considerable portion of both torso and limbs was covered with short hair, and their physical proportions were in many respects apelike, though not so much so as were Ahm's. They carried themselves in a more erect position, although their arms were considerably longer than those of the Neanderthal man. As I watched them, I saw that they possessed a language, that they had knowledge of fire and that they carried besides the wooden club of Ahm a thing which resembled a crude stone hatchet. Evidently they were very low in the scale of humanity, but they were a step upward from those I had previously seen in Caspak.
Lys Is Found—An Attack and a Deadly Shot
BUT what interested me most was the slender figure of a dainty girl, clad only in a thin bit of muslin which scarce covered her knees—a bit of muslin torn and ragged about the lower hem. It was Lys, and she was alive and so far as I could see, unharmed. A huge brute with thick lips and prognathous jaw stood at her shoulder. He was talking loudly and gesticulating wildly. I was close enough to hear his words, which were similar to the language of Ahm, though much fuller, for there were many words I could not understand. However, I caught the gist of what he was saying—which in effect was that he had found and captured this Galu, that she was his and that he defied anyone to question his right of possession. It appeared to me, as I afterward learned was the fact, that I was witnessing the most primitive of marriage ceremonies. The assembled members of the tribe looked on and listened in a sort of dull and perfunctory apathy, for the speaker was by far the mightiest of the clan. There seemed no one to dispute his claims when he said, or rather shouted, in stentorian tones: "I am Tsa. This is my she. Who wishes her more than Tsa?"
"I do," I said in the language of Ahm, and I stepped out into the firelight before them. Lys gave a little cry of joy and started toward me, but Tsa grasped her arm and dragged her back.
"Who are you?" shrieked Tsa. "I kill! I kill! I kill!"
"The she is mine," I replied, "and I have come to claim her. I kill if you do not let her come to me." And I raised my pistol to a level with his heart. Of course, the creature had no conception of the purpose of the strange little implement which I was poking toward him. With a sound that was half human and half the growl of a wild beast, he sprang toward me. I aimed at his heart and fired, and as he sprawled headlong to the ground, the others of his tribe, overcome by fright at the report of the pistol, scattered toward the cliffs—while Lys, with outstretched arms, ran toward me.
As I crushed her to me, there rose from the black night behind us and then to our right and to our left a series of frightful screams and shrieks, bellowings, roars and growls. It was the night-life of this jungle world coming into its own—the huge, carnivorous nocturnal beasts which make the nights of Caspak hideous. A shuddering sob ran through Lys' figure. "O God," she cried, "give me the strength to endure, for his sake!" I saw that she was upon the verge of a breakdown, after all that she must have passed through of fear and horror that day, and I tried to quiet and reassure her as best I might; but even to me the future looked most unpromising, for what chance of life had we against the frightful hunters of the night who even now were prowling closer to us?
Now I turned to see what had become of the tribe, and in the fitful glare of the fire I perceived that the face of the cliff was pitted with large holes into which the man-things were clambering. "Come," I said to Lys, "we must follow them. We cannot last a half-hour out here. We must find a cave." Already we could see the blazing green eyes of the hungry carnivora. I seized a brand from the fire and hurled it out into the night, and there came back an answering chorus of savage and rageful protest; but the eyes vanished for a short time. Selecting a burning branch for each of us,
