The hideous face, incapable of registering emotion, gave no clue to what was passing in the enormous brain. Was he nursing thoughts of anger, of hate, of revenge? Tara of Helium could not guess, nor did she care. The worst had happened. She had tried to escape and she had failed. There would never be another opportunity.

«Come!» said Ghek. «We will return to the tower.» The deadly monotone of his voice was unbroken. It was worse than anger, for it revealed nothing of his intentions. It but increased her horror of these great brains that were beyond the possibility of human emotions.

And so she was dragged back to her prison in the tower and Ghek took up his vigil again, squatting by the doorway, but now he carried a naked sword in his hand and did not quit his rykor, only to change to another that he had brought to him when the first gave indications of weariness. The girl sat looking at him. He had not been unkind to her, but she felt no sense of gratitude, nor, on the other hand, any sense of hatred. The brains, incapable themselves of any of the finer sentiments, awoke none in her. She could not feel gratitude, or affection, or hatred of them. There was only the same unceasing sense of horror in their presence. She had heard great scientists discuss the future of the red race and she recalled that some had maintained that eventually the brain would entirely dominate the man. There would be no more instinctive acts or emotions, nothing would be done on impulse; but on the contrary reason would direct our every act. The propounder of the theory regretted that he might never enjoy the blessings of such a state, which, he argued, would result in the ideal life for mankind.

Tara of Helium wished with all her heart that this learned scientist might be here to experience to the full the practical results of the fulfillment of his prophecy. Between the purely physical rykor and the purely mental kaldane there was little choice; but in the happy medium of normal, and imperfect man, as she knew him, lay the most desirable state of existence. It would have been a splendid object lesson, she thought, to all those idealists who seek mass perfection in any phase of human endeavor, since here they might discover the truth that absolute perfection is as little to be desired as is its antithesis.

Gloomy were the thoughts that filled the mind of Tara of Helium as she awaited the summons from Luud-the summons that could mean for her but one thing; death. She guessed why he had sent for her and she knew that she must find the means for self-destruction before the night was over; but still she clung to hope and to life. She would not give up until there was no other way. She startled Ghek once by exclaiming aloud, almost fiercely: «I still live!»

«What do you mean?» asked the kaldane.

«I mean just what I say,» she replied. «I still live and while I live I may still find a way. Dead, there is no hope.»

«Find a way to what?» he asked.

«To life and liberty and mine own people,» she responded.

«None who enters Bantoom ever leaves,» he droned.

She did not reply and after a time he spoke again. «Sing to me,» he said.

It was while she was singing that four warriors came to take her to Luud. They told Ghek that he was to remain where he was.

«Why?» asked Ghek.

«You have displeased Luud,» replied one of the warriors.

«How?» demanded Ghek.

«You have demonstrated a lack of uncontaminated reasoning power. You have permitted sentiment to influence you, thus demonstrating that you are a defective. You know the fate of defectives.»

«I know the fate of defectives, but I am no defective,» insisted Ghek.

«You permitted the strange noises which issue from her throat to please and soothe you, knowing well that their origin and purpose had nothing whatever to do with logic or the powers of reason. This in itself constitutes an unimpeachable indictment of weakness. Then, influenced doubtless by an illogical feeling of sentiment, you permitted her to walk abroad in the fields to a place where she was able to make an almost successful attempt to escape. Your own reasoning power, were it not defective, would convince you that you are unfit. The natural, and reasonable, consequence is destruction. Therefore you will be destroyed in such a way that the example will be beneficial to all other kaldanes of the swarm of Luud. In the meantime you will remain where you are.»

«You are right,» said Ghek. «I will remain here until Luud sees fit to destroy me in the most reasonable manner.»

Tara of Helium shot a look of amazement at him as they led her from the chamber. Over her shoulder she called back to him: «Remember, Ghek, you still live!» Then they led her along the interminable tunnels to where Luud awaited her.

When she was conducted into his presence he was squatting in a corner of the chamber upon his six spidery legs. Near the opposite wall lay his rykor, its beautiful form trapped in gorgeous harness-a dead thing without a guiding kaldane. Luud dismissed the warriors who had accompanied the prisoner. Then he sat with his terrible eyes fixed upon her and without speaking for some time. Tara of Helium could but wait. What was to come she could only guess. When it came would be sufficiently the time to meet it. There was no necessity for anticipating the end. Presently Luud spoke.

«You think to escape,» he said, in the deadly, expressionless monotone of his kind-the only possible result of orally expressing reason uninfluenced by sentiment. «You will not escape. You are merely the embodiment of two imperfect things-an imperfect brain and an imperfect body. The two cannot exist together in perfection. There you see a perfect body.» He pointed toward the rykor. «It has no brain. Here,» and he raised one of his chelae to his head, «is the perfect brain. It needs no body to function perfectly and properly as a brain. You would pit your feeble intellect against mine! Even now you are planning to slay me. If you are thwarted in that you expect to slay yourself. You will learn the power of mind over matter. I am the mind. You are the matter. What brain you have is too weak and ill-developed to deserve the name of brain. You have permitted it to be weakened by impulsive acts dictated by sentiment. It has no value. It has practically no control over your existence. You will not kill me. You will not kill yourself. When I am through with you you shall be killed if it seems the logical thing to do. You have no conception of the possibilities for power which lie in a perfectly developed brain. Look at that rykor. He has no brain. He can move but slightly of his own volition. An inherent mechanical instinct that we have permitted to remain in him allows him to carry food to his mouth; but he could not find food for himself. We have to place it within his reach and always in the same place. Should we put food at his feet and leave him alone he would starve to death. But now watch what a real brain may accomplish.»

He turned his eyes upon the rykor and squatted there glaring at the insensate thing. Presently, to the girl's horror, the headless body moved. It rose slowly to its feet and crossed the room to Luud; it stooped and took the hideous head in its hands; it raised the head and set it on its shoulders.

«What chance have you against such power?» asked Luud. «As I did with the rykor so can I do with you.»

Tara of Helium made no reply. Evidently no vocal reply was necessary.

«You doubt my ability!» stated Luud, which was precisely the fact, though the girl had only thought it-she had not said it.

Luud crossed the room and lay down. Then he detached himself from the body and crawled across the floor until he stood directly in front of the circular opening through which she had seen him emerge the day that she had first been brought to his presence. He stopped there and fastened his terrible eyes upon her. He did not speak, but his eyes seemed to be boring straight to the center of her brain. She felt an almost irresistible force urging her toward the kaldane. She fought to resist it; she tried to turn away her eyes, but she could not. They were held as in horrid fascination upon the glittering, lidless orbs of the great brain that faced her. Slowly, every step a painful struggle of resistance, she moved toward the horrific monster. She tried to cry aloud in an effort to awaken her numbing faculties, but no sound passed her lips. If those eyes would but turn away, just for an instant, she felt that she might regain the power to control her steps; but the eyes never left hers. They seemed but to burn deeper and deeper, gathering up every vestige of control of her entire nervous system.
