"Who can tell?" he rejoined.

"Who can tell?" he rejoined.  "They may constitute the link between ape and man, all traces of which have been swallowed by the countless convulsions which have racked the outer crust, or they may be merely the result of evolution along slightly different lines—either is quite possible." Further speculation was interrupted by the appearance of several of our captors before the entrance of the hut.  Two of them entered and dragged us forth.  The perilous pathways and the surrounding trees were filled with the black ape-men, their females, and their young.  There was not an ornament, a weapon, or a garment among the lot. "Quite low in the scale of creation," commented Perry. "Quite high enough to play the deuce with us, though," I replied.  "Now what do you suppose they intend doing with us?" We were not long in learning.  As on the occasion of our trip to the village we were seized by a couple of the powerful creatures and whirled away through the tree tops, while about us and in our wake raced a chattering, jabbering, grinning horde of sleek, black ape-things. Twice my bearers missed their footing, and my heart ceased beating as we plunged toward instant death among the tangled deadwood beneath. But on both occasions those lithe, powerful tails reached out and found sustaining branches, nor did either of the creatures loosen their grasp upon me.  In fact, it seemed that the incidents were of no greater moment to them than would be the stubbing of one's toe at a street crossing in the outer world—they but laughed uproariously and sped on with me. For some time they continued through the forest—how long I could not guess for I was learning, what was later borne very forcefully to my mind, that time ceases to be a factor the moment means for measuring it cease to exist.  Our watches were gone, and we were living beneath a stationary sun.  Already I was puzzled to compute the period of time which had elapsed since we broke through the crust of the inner world. It might be hours, or it might be days—who in the world could tell where it was always noon!  By the sun, no time had elapsed—but my judgment told me that we must have been several hours in this strange world. Presently the forest terminated, and we came out upon a level plain.  A short distance before us rose a few low, rocky hills.  Toward these our captors urged us, and after a short time led us through a narrow pass into a tiny, circular valley.  Here they got down to work, and we were soon convinced that if we were not to die to make a Roman holiday, we were to die for some other purpose.  The attitude of our captors altered immediately as they entered the natural arena within the rocky hills.  Their laughter ceased.  Grim ferocity marked their bestial faces—bared fangs menaced us. We were placed in the center of the amphitheater—the thousand creatures forming a great ring about us.  Then a wolf-dog was brought—hyaenadon Perry called it—and turned loose with us inside the circle.  The thing's body was as large as that of a full-grown mastiff, its legs were short and powerful, and its jaws broad and strong.  Dark, shaggy hair covered its back and sides, while its breast and
