Foster's eyes widened in horror as he saw the object in which the trailing tendrils of the luminous slugs were sunk. It was the naked body of Carter. As those sucking tendrils drew out the substance of his skeleton, Carter's body was changing slowly, horribly, sinking into a flabby mass of puttylike flesh. The dormant bodies of the great slugs glowed perceptibly brighter as they fed, and the pulsations of opalescence quickened. The Shining Ones were beginning to awaken. Faint but unmistakable there came to Foster's ears a low singing drone from the group. He shuddered. He knew now why Jeff Peters' shadow had seemed so grotesquely _boneless_. That droning buzzing sound he had heard from the black tent had been the feeding cry of a Shining One--of Layroh. Then, his horrible feast ended, Layroh had blasted what remained of his victim into nothingness with the black ray. * * * * * Foster was abruptly startled into action as Layroh turned from watching the central case. Picking up the black ray projector, he started toward the pit-room door. Foster scrambled down. With Garrigan he joined the tensely waiting group beside the door. There was the sound of the mechanism unlocking. The door opened and Layroh came striding in. In a concerted rush the men were upon him. Foster's hurtling dive for the black ray projector knocked the apparatus out of Layroh's hands. It crashed to the floor with a violence that left it shattered and useless. Swept off his feet by the savage fury of the unexpected attack, Layroh went to the floor beneath the writhing group of men. The metal sinews of his magnificent body brought him to his knees in one mighty effort, but the numbers of his assailants were too great. Again he was beaten down while powerful hands tore at his limbs. The metal of the ingenious machine that was Layroh's body began twisting and giving way before the savagery of the assault. He staggered to his feet, flinging the men aside in one last mad surge of power, and lurched toward the cavern. His effort to slam the door closed behind him was blocked by the swift leap of two of the men. Layroh staggered on into the cavern. Then suddenly the torn framework of his legs collapsed completely, and he fell heavily on his back.
