As Thuria, swift racer of the night, shot again into the sky the scene changed. As by magic a new aspect fell athwart the face of Nature. It was as though in the instant one had been transported from one planet to another. It was the age-old miracle of the Martian nights that is always new, even to Martians-two moons resplendent in the heavens, where one had been but now; conflicting, fast-changing shadows that altered the very hills themselves; far Cluros, stately, majestic, almost stationary, shedding his steady light upon the world below; Thuria, a great and glorious orb, swinging swift across the vaulted dome of the blue-black night, so low that she seemed to graze the hills, a gorgeous spectacle that held the girl now beneath the spell of its enchantment as it always had and always would.

«Ah, Thuria, mad queen of heaven!» murmured Tara of Helium. «The hills pass in stately procession, their bosoms rising and falling; the trees move in restless circles; the little grasses describe their little arcs; and all is movement, restless, mysterious movement without sound, while Thuria passes.» The girl sighed and let her gaze fall again to the stern realities beneath. There was no mystery in the huge banths. He who had discovered her squatted there looking hungrily up at her. Most of the others had wandered away in search of other prey, but a few remained hoping yet to bury their fangs in that soft body.

The night wore on. Again Thuria left the heavens to her lord and master, hurrying on to keep her tryst with the Sun in other skies. But a single banth waited impatiently beneath the tree which harbored Tara of Helium. The others had left, but their roars, and growls, and moans thundered or rumbled, or floated back to her from near and far. What prey found they in this little valley? There must be something that they were accustomed to find here that they should be drawn in so great numbers. The girl wondered what it could be.

How long the night! Numb, cold, and exhausted, Tara of Helium clung to the tree in growing desperation, for once she had dozed and almost fallen. Hope was low in her brave little heart. How much more could she endure? She asked herself the question and then, with a brave shake of her head, she squared her shoulders. «I still live!» she said aloud.

The banth looked up and growled.

Came Thuria again and after awhile the great Sun-a flaming lover, pursuing his heart's desire. And Cluros, the cold husband, continued his serene way, as placid as before his house had been violated by this hot Lothario. And now the Sun and both Moons rode together in the sky, lending their far mysteries to make weird the Martian dawn. Tara of Helium looked out across the fair valley that spread upon all sides of her. It was rich and beautiful, but even as she looked upon it she shuddered, for to her mind came a picture of the headless things that the towers and the walls hid. Those by day and the banths by night! Ah, was it any wonder that she shuddered?

With the coming of the Sun the great Barsoomian lion rose to his feet. He turned angry eyes upon the girl above him, voiced a single ominous growl, and slunk away toward the hills. The girl watched him, and she saw that he gave the towers as wide a berth as possible and that he never took his eyes from one of them while he was passing it. Evidently the inmates had taught these savage creatures to respect them. Presently he passed from sight in a narrow defile, nor in any direction that she could see was there another. Momentarily at least the landscape was deserted. The girl wondered if she dared to attempt to regain the hills and her flier. She dreaded the coming of the workmen to the fields as she was sure they would come. She shrank from again seeing the headless bodies, and found herself wondering if these things would come out into the fields and work. She looked toward the nearest tower. There was no sign of life there. The valley lay quiet now and deserted. She lowered herself stiffly to the ground. Her muscles were cramped and every move brought a twinge of pain. Pausing a moment to drink again at the stream she felt refreshed and then turned without more delay toward the hills. To cover the distance as quickly as possible seemed the only plan to pursue. The trees no longer offered concealment and so she did not go out of her way to be near them. The hills seemed very far away. She had not thought, the night before, that she had traveled so far. Really it had not been far, but now, with the three towers to pass in broad daylight, the distance seemed great indeed.

The second tower lay almost directly in her path. To make a detour would not lessen the chance of detection, it would only lengthen the period of her danger, and so she laid her course straight for the hill where her flier was, regardless of the tower. As she passed the first enclosure she thought that she heard the sound of movement within, but the gate did not open and she breathed more easily when it lay behind her. She came then to the second enclosure, the outer wall of which she must circle, as it lay across her route. As she passed close along it she distinctly heard not only movement within, but voices. In the world-language of Barsoom she heard a man issuing instructions-so many were to pick usa, so many were to irrigate this field, so many to cultivate that, and so on, as a foreman lay out the day's work for his crew.

Tara of Helium had just reached the gate in the outer wall. Without warning it swung open toward her. She saw that for a moment it would hide her from those within and in that moment she turned and ran, keeping close to the wall, until, passing out of sight beyond the curve of the structure, she came to the opposite side of the enclosure. Here, panting from her exertion and from the excitement of her narrow escape, she threw herself among some tall weeds that grew close to the foot of the wall. There she lay trembling for some time, not even daring to raise her head and look about. Never before had Tara of Helium felt the paralyzing effects of terror. She was shocked and angry at herself, that she, daughter of John Carter, Warlord of Barsoom, should exhibit fear. Not even the fact that there had been none there to witness it lessened her shame and anger, and the worst of it was she knew that under similar circumstances she would again be equally as craven. It was not the fear of death-she knew that. No, it was the thought of those headless bodies and that she might see them and that they might even touch her-lay hands upon her-seize her. She shuddered and trembled at the thought.

After a while she gained sufficient command of herself to raise her head and look about. To her horror she discovered that everywhere she looked she saw people working in the fields or preparing to do so. Workmen were coming from other towers. Little bands were passing to this field and that. They were even some already at work within thirty ads of her-about a hundred yards. There were ten, perhaps, in the party nearest her, both men and women, and all were beautiful of form and grotesque of face. So meager were their trappings that they were practically naked; a fact that was in no way remarkable among the tillers of the fields of Mars. Each wore the peculiar, high leather collar that completely hid the neck, and each wore sufficient other leather to support a single sword and a pocket-pouch. The leather was very old and worn, showing long, hard service, and was absolutely plain with the exception of a single device upon the left shoulder. The heads, however, were covered with ornaments of precious metals and jewels, so that little more than eyes, nose, and mouth were discernible. These were hideously inhuman and yet grotesquely human at the same time. The eyes were far apart and protruding, the nose scarce more than two small, parallel slits set vertically above a round hole that was the mouth. The heads were peculiarly repulsive-so much so that it seemed unbelievable to the girl that they formed an integral part of the beautiful bodies below them.
