As Tara of Helium looked down into the enclosure surrounding the nearest tower, her brows contracted momentarily in frowning surprise, and then her eyes went wide in an expression of incredulity tinged with horror, for what she saw was a score or two of human bodies--naked and headless. For a long moment she watched, breathless; unable to believe the evidence of her own eyes--that these grewsome things moved and had life! She saw them crawling about on hands and knees over and across one another, searching about with their fingers. And she saw some of them at troughs, for which the others seemed to be searching, and those at the troughs were taking something from these receptacles and apparently putting it in a hole where their necks should have been. They were not far beneath her--she could see them distinctly and she saw that there were the bodies of both men and women, and that they were beautifully proportioned, and that their skin was similar to hers, but of a slightly lighter red. At first she had thought that she was looking upon a shambles and that the bodies, but recently decapitated, were moving under the impulse of muscular reaction; but presently she realized that this was their normal condition. The horror of them fascinated her, so that she could scarce take her eyes from them. It was evident from their groping hands that they were eyeless, and their sluggish movements suggested a rudimentary nervous system and a correspondingly minute brain. The girl wondered how they subsisted for she could not, even by the wildest stretch of imagination, picture these imperfect creatures as intelligent tillers of the soil. Yet that the soil of the valley was tilled was evident and that these things had food was equally so. But who tilled the soil? Who kept and fed these unhappy things, and for what purpose? It was an enigma beyond her powers of deduction. The sight of food aroused again a consciousness of her own gnawing hunger and the thirst that parched her throat. She could see both food and water within the enclosure; but would she dare enter even should she find means of ingress? She doubted it, since the very thought of possible contact with these grewsome creatures sent a shudder through her frame.
