Shortly after noon of the second day the storm commenced to abate, and before the sun went down, the little craft upon which Tara of Helium had hovered between life and death these many hours drifted slowly before a gentle breeze above a landscape of rolling hills that once had been lofty mountains upon a Martian continent. The girl was exhausted from loss of sleep, from lack of food and drink, and from the nervous reaction consequent to the terrifying experiences through which she had passed. In the near distance, just topping an intervening hill, she caught a momentary glimpse of what appeared to be a dome-capped tower. Quickly she dropped the flier until the hill shut it off from the view of the possible occupants of the structure she had seen. The tower meant to her the habitation of man, suggesting the presence of water and, perhaps, of food. If the tower was the deserted relic of a bygone age she would scarcely find food there, but there was still a chance that there might be water. If it was inhabited, then must her approach be cautious, for only enemies might be expected to abide in so far distant a land. Tara of Helium knew that she must be far from the twin cities of her grandfather's empire, but had she guessed within even a thousand haads of the reality, she had been stunned by realization of the utter hopelessness of her state.

Keeping the craft low, for the buoyancy tanks were still intact, the girl skimmed the ground until the gently-moving wind had carried her to the side of the last hill that intervened between her and the structure she had thought a man-built tower. Here she brought the flier to the ground among some stunted trees, and dragging it beneath one where it might be somewhat hidden from craft passing above, she made it fast and set forth to reconnoiter. Like most women of her class she was armed only with a single slender blade, so that in such an emergency as now confronted her she must depend almost solely upon her cleverness in remaining undiscovered by enemies. With utmost caution she crept warily toward the crest of the hill, taking advantage of every natural screen that the landscape afforded to conceal her approach from possible observers ahead, while momentarily she cast quick glances rearward lest she be taken by surprise from that quarter.

She came at last to the summit, where, from the concealment of a low bush, she could see what lay beyond. Beneath her spread a beautiful valley surrounded by low hills. Dotting it were numerous circular towers, dome-capped, and surrounding each tower was a stone wall enclosing several acres of ground. The valley appeared to be in a high state of cultivation. Upon the opposite side of the hill and just beneath her was a tower and enclosure. It was the roof of the former that had first attracted her attention. In all respects it seemed identical in construction with those further out in the valley—a high, plastered wall of massive construction surrounding a similarly constructed tower, upon whose gray surface was painted in vivid colors a strange device. The towers were about forty sofads in diameter, approximately forty earth-feet, and sixty in height to the base of the dome. To an Earth man they would have immediately suggested the silos in which dairy farmers store ensilage for their herds; but closer scrutiny, revealing an occasional embrasured opening together with the strange construction of the domes, would have altered such a conclusion. Tara of Helium saw that the domes seemed to be faced with innumerable prisms of glass, those that were exposed to the declining sun scintillating so gorgeously as to remind her suddenly of the magnificent trappings of Gahan of Gathol. As she thought of the man she shook her head angrily, and moved cautiously forward a foot or two that she might get a less obstructed view of the nearer tower and its enclosure.

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.

Then her eyes wandered again out across the valley until presently they picked out what appeared to be a tiny stream winding its way through the center of the farm lands—a strange sight upon Barsoom. Ah, if it were but water! Then might she hope with a real hope, for the fields would give her sustenance which she could gain by night, while by day she hid among the surrounding hills, and sometime, yes, sometime she knew, the searchers would come, for John Carter, Warlord of Barsoom, would never cease to search for his daughter until every square haad of the planet had been combed again and again. She knew him and she knew the warriors of Helium and so she knew that could she but manage to escape harm until they came, they would indeed come at last.

She would have to wait until dark before she dare venture into the valley, and in the meantime she thought it well to search out a place of safety nearby where she might be reasonably safe from savage beasts. It was possible that the district was free from carnivora, but one might never be sure in a strange land. As she was about to withdraw behind the brow of the hill her attention was again attracted to the enclosure below. Two figures had emerged from the tower. Their beautiful bodies seemed identical with those of the headless creatures among which they moved, but the newcomers were not headless. Upon their shoulders were heads that seemed human, yet which the girl intuitively sensed were not human. They were just a trifle too far away for her to see them distinctly in the waning light of the dying day, but she knew that they were too large, they were out of proportion to the perfectly proportioned bodies, and they were oblate in form. She could see that the men wore some manner of harness to which were slung the customary long-sword and short-sword of the Barsoomian warrior, and that about their short necks were massive leather collars cut to fit closely over the shoulders and snugly to the lower part of the head. Their features were scarce discernible, but there was a suggestion of grotesqueness about them that carried to her a feeling of revulsion.

The two carried a long rope to which were fastened, at intervals of about two sofads, what she later guessed were light manacles, for she saw the warriors passing among the poor creatures in the enclosure and about the right wrist of each they fastened one of the manacles. When all had been thus fastened to the rope one of the warriors commenced to pull and tug at the loose end as though attempting to drag the headless company toward the tower, while the other went among them with a long, light whip with which he flicked them upon the naked skin. Slowly, dully, the creatures rose to their feet and between the tugging of the warrior in front and the lashing of him behind the hopeless band was finally herded within the tower. Tara of Helium shuddered as she turned away. What manner of creatures were these?

Suddenly it was night. The Barsoomian day had ended, and then the brief period of twilight that renders the transition from daylight to darkness almost as abrupt as the switching off of an electric light, and Tara of Helium had found no sanctuary. But perhaps there were no beasts to fear, or rather to avoid—Tara of Helium liked not the word fear. She would have been glad, however, had there been a cabin, even a very tiny cabin, upon her small flier; but there was no cabin. The interior of the hull was completely taken up by the buoyancy tanks. Ah, she had it! How stupid of her not to have thought of it before! She could moor the craft to the tree beneath which it rested and let it rise the length of the rope. Lashed to the deck rings she would then be safe from any roaming beast of prey that chanced along. In the morning she could drop to the ground again before the craft was discovered.

As Tara of Helium crept over the brow of the hill down toward the valley, her presence was hidden by the darkness of the night from the sight of any chance observer who might be loitering by a window in the nearby tower. Cluros, the farther moon, was just rising above the horizon to commence his leisurely journey through the heavens. Eight zodes later he would set—a trifle over nineteen and a half Earth hours—and during that time Thuria, his vivacious mate, would have circled the planet twice and be more than half way around on her third trip. She had but just set. It would be more than three and a half hours before she shot above the opposite horizon to hurtle, swift and low, across the face of the dying planet. During this temporary absence of the mad moon Tara of Helium hoped to find both food and water, and gain again the safety of her flier's deck.
