Scarcely had they entered the grotto when it became apparent to Tanar that these creatures could see, a thing that he had commenced to suspect shortly after his capture, for now, at sight of him, they commenced to scream and make strange, whistling sounds, and from the openings of many of the high flung caves within the walls heads protruded and the hideous, eyeless faces seemed to be bending eyes upon him. One cry seemed to rise above all others as he was borne across the grotto towards the creature sitting in the niche. It was “Flesh! Flesh!” and it sounded grewsome and horrible in its suggestiveness. Flesh! Yes, he knew that they ate human flesh and it seemed now that they were but awaiting a signal to leap upon him and devour him alive, tearing pieces from him with their heavy claws. But when one did rush upon him there came a scream from the creature in the niche and the fellow desisted, even as one of his captors had turned to defend him. The cavern crossed at last, Tanar was deposited upon his feet in front of the creature squatting in the niche. Tanar could see the great eyeballs revolving beneath the pulsing skin of the protuberances and though he could see no eyes, he knew that he was being examined coldly and calculatingly. “Where did you get it?” finally demanded the creature, addressing Tanar’s captors. “He tumbled into the Well of Sounding Water,” replied one. “How do you know?” “He told us so.” “Do you believe him?” “There was no other way in which he could enter the land of the Coripies,” replied one of the captors. “Perhaps he was leading a party in to slay us,” said the creature in the niche. “Go, many of you, and search the corridors and the tunnels about the Well of Sounding Water.” Then the creature turned to Tanar’s captors. “Take this and put it with the others; we have not yet enough.” Tanar was now again placed upon the back of a Coripi, who carried him across the grotto and up one of the pathways cut into the face of the limestone wall. Ascending this pathway a short distance the creature turned into one of the cave openings, and Tanar found himself again in a narrow, dark, winding tunnel. The tunnels and corridors through which he had already been conducted had impressed upon Tanar the great antiquity of this underground labyrinthine world, since there was every evidence that the majority of these tunnels had been hewn from the limestone rock or natural passageways enlarged to accommodate the Coripies, and as these creatures appeared to have no implements other than their heavy, three-toed claws the construction of the tunnels must have represented the labor of countless thousands of individuals over a period of many ages. Tanar, of course, had only a hazy conception of what we describe as the measurable aspect of duration. His consideration of the subject concerned itself with the countless millions of times that these creatures must have slept and eaten during the course of their stupendous labors.
