But more eloquent than the ape-man's halting words was the trembling of his muscle-knotted shoulders in a fear that struck him limp at Chet's feet. And the pilot realized that the fear was inspired in part by the thought in the savage mind that his master might ask him to go closer to the place of dread. He had followed them once and had struck down a messenger, but this was when he was avid with curiosity and half-worshipful of the white men as gods. Now, to go that dreadful way in full daylight!--it was more than Towahg could face. * * * * * Chet patted the cringing shoulder with a kindly hand. "Get up, Towahg," he ordered and pointed back toward the jungle. "Towahg wait outside; wait today and to-night!" He gave the ape-man's sign of the open and closed hand to signify one day and one night, and Towahg's grunt was half in relief and half in understanding as he slipped back into hiding where the jungle pressed close. Chet turned again to the pyramid. "They're down there," he told himself, "facing God knows what. And now it's sink or swim, and I'm almighty afraid I know which it's to be. But we'll take it together: 'When Krargh sends for you, you never come back.'" No jungle sounds were here in this silent arena, no flashing of leather-winged birds nor scuttling of little, odd creatures of the ground. It was as if some terror had spread its dark wings above the place, a terror unseen of men. But the little, wild things of earth and air had seen, and they had fled long since from a place unclean and unfit for life. Chet felt the silence pressing heavily upon him as he took his hand from the rock at his side and stepped out into the arena. And the vast amphitheater seemed peopled with phantom shapes that sat in serried rows and watched him with dead and terrible eyes, while he went the long way to the pyramid's base, and his feet found the rough stone ascent.... CHAPTER XXI _The Monstrous Something_ The way to the top of the pyramid was long. One look Chet allowed himself out over this world--one slow, sweeping gaze that took in the bare floor at the pyramid's base, a level platform of rock some distance in front of the pyramid, the hard black and white of the walled oval, the sea of waving green that was the jungle beyond, and, beyond that, hills, misty and shimmering in the noonday heat. And nestled there, beyond that last bare ridge, must be the valley of happiness, Diane Delacouer's "Happy Valley." Chet Bullard turned abruptly where the projecting capstone hung heavy above a shadowed entrance. He entered the blackness within, stopped once in choking nausea as the first wave of vile air struck him, then fought his way on till his searching feet found the stairway, and he knew he was descending into a pit that held something inhumanly horrible--an abomination unto all gods of decency and right.
