Seeing therefore that I must be armed for defence against an uncanny and unseen attack in the dark, I grouped about me the largest of the fragments of rock which were strown upon all parts of the floor of the cavern in the vicinity, and, grasping one in each hand for immediate use, awaited with resignation the inevitable result. Meanwhile the hideous pattering of the paws drew near. Certainly, the conduct of the creature was exceedingly strange. Most of the time, the tread seemed to be that of a quadruped, walking with a singular lack of unison betwixt hind and fore feet, yet at brief and infrequent intervals I fancied that but two feet were engaged in the process of locomotion. I wondered what species of animal was to confront me; it must, I thought, be some unfortunate beast who had paid for its curiosity to investigate one of the entrances of the fearful grotto with a lifelong confinement in its interminable recesses. It doubtless obtained as food the eyeless fish, bats, and rats of the cave, as well as some of the ordinary fish that are wafted in at every freshet of Green River, which communicates in some occult manner with the waters of the cave. I occupied my terrible vigil with grotesque conjectures of what alterations cave life might have wrought in the physical structure of the beast, remembering the awful appearances ascribed by local tradition to the consumptives who had died after long residence in the cavern. Then I remembered with a start that, even should I succeed in killing my antagonist, I should never behold its form, as my torch had long since been extinct, and I was entirely unprovided with matches. The tension on my brain now became frightful. My disordered fancy conjured up hideous and fearsome shapes from the sinister darkness that surrounded me, and that actually seemed to press upon my body. Nearer, nearer, the dreadful footfalls approached. It seemed that I must give vent to a piercing scream, yet had I been sufficiently irresolute to attempt such a thing, my voice could scarce have responded. I was petrified, rooted to the spot. I doubted if my right arm would allow me to hurl its missile at the oncoming thing when the crucial moment should arrive. Now the steady pat, pat, of the steps was close at hand; now, very close. I could hear the laboured breathing of the animal, and terror-struck as I was, I realised that it must have come from a considerable distance, and was correspondingly fatigued. Suddenly the spell broke. My right hand, guided by my ever trustworthy sense of hearing, threw with full force the sharp-angled bit of limestone which it contained, toward that point in the darkness from which emanated the breathing and pattering, and, wonderful to relate, it nearly reached its goal, for I heard the thing jump, landing at a distance away, where it seemed to pause.
Having readjusted my aim, I discharged my second missile, this time most effectively, for with a flood of joy I listened as the creature fell in what sounded like a complete collapse, and evidently remained prone and unmoving. Almost overpowered by the great relief which rushed over me, I reeled back against the wall. The breathing continued, in heavy, gasping inhalations and expirations, whence I realised that I had no more than wounded the creature. And now all desire to examine the thing ceased. At last something allied to groundless, superstitious, fear had entered my brain, and I did not approach the body, nor did I continue to cast stones at it in order to complete the extinction of its life. Instead, I ran at full speed in what was, as nearly as I could estimate in my frenzied condition, the direction from which I had come. Suddenly I heard a sound, or rather, a regular succession of sounds. In another instant they had resolved themselves into a series of sharp, metallic clicks. This time there was no doubt. It was the guide. And then I shouted, yelled, screamed, even shrieked with joy as I beheld in the vaulted arches above the faint and glimmering effulgence which I knew to be the reflected light of an approaching torch. I ran to meet the flare, and before I could completely understand what had occurred, was lying upon the ground at the feet of the guide, embracing his boots, and gibbering, despite my boasted reserve, in a most meaningless and idiotic manner, pouring out my terrible story, and at the same time overwhelming my auditor with protestations of gratitude. At length I awoke to something like my normal consciousness. The guide had noted my absence upon the arrival of the party at the entrance of the cave, and had, from his own intuitive sense of direction, proceeded to make a thorough canvass of the by-passages just ahead of where he had last spoken to me, locating my whereabouts after a quest of about four hours.
By the time he had related this to me, I, emboldened by his torch and his company, began to reflect upon the strange beast which I had wounded but a short distance back in the darkness, and suggested that we ascertain, by the rushlight’s aid, what manner of creature was my victim. Accordingly I retraced my steps, this time with a courage born of companionship, to the scene of my terrible experience. Soon we descried a white object upon the floor, an object whiter even than the gleaming limestone itself. Cautiously advancing, we gave vent to a simultaneous ejaculation of wonderment, for of all the unnatural monsters either of us had in our lifetimes beheld, this was in surpassing degree the strangest. It appeared to be an anthropoid ape of large proportions, escaped, perhaps, from some itinerant menagerie. Its hair was snow-white, a thing due no doubt to the bleaching action of a long existence within the inky confines of the cave, but it was also surprisingly thin, being indeed largely absent save on the head, where it was of such length and abundance that it fell over the shoulders in considerable profusion. The face was turned away from us, as the creature lay almost directly upon it. The inclination of the limbs was very singular, explaining, however, the alternation in their use which I had before noted, whereby the beast used sometimes all four, and on other occasions but two for its progress. From the tips of the fingers or toes long nail-like claws extended. The hands or feet were not prehensile, a fact that I ascribed to that long residence in the cave which, as I before mentioned, seemed evident from the all-pervading and almost unearthly whiteness so characteristic of the whole anatomy. No tail seemed to be present.
