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.

So fascinated was Tara of Helium that she could scarce take her eyes from the strange creatures—­a fact that was to prove her undoing, for in order that she might see them she was forced to expose a part of her own head and presently, to her consternation, she saw that one of the creatures had stopped his work and was staring directly at her.  She did not dare move, for it was still possible that the thing had not seen her, or at least was only suspicious that some creature lay hid among the weeds.  If she could allay this suspicion by remaining motionless the creature might believe that he had been mistaken and return to his work; but, alas, such was not to be the case.  She saw the thing call the attention of others to her and almost immediately four or five of them started to move in her direction.
