"This plan that I have chosen is simplicity itself provided that I can count upon just two essential factors-skill and self-interested loyalty in an assistant. My body is about worn out. I must have a new one. My laboratory is filled with wonderful bodies, young and complete with potential strength and health. I have but to select one of these and have my skilled assistant transfer my brain from this old carcass to the new one." He paused.

"I understand now, why you have trained me," I said. "It has puzzled me greatly."

"Thus and thus only may I continue my labors," he went on, "and thus may Barsoom be assured a continuance practically indefinitely, of the benefits that my brain may bestow upon her children. I may live for ever, provided I always have a skilled assistant, and I may assure myself of such by seeing to it that he never dies; when he wears out one organ, or his whole body, I can replace either from my great storehouse of perfect parts, and for me he can perform the same service. Thus may we continue to live indefinitely; for the brain, I believe, is almost deathless, unless injured or attacked by disease.

"You are not ready as yet to be entrusted with this important task. You must transfer many more brains and meet with and overcome the various irregularities and idiosyncrasies that constitute the never failing differences that render no two operations identical. When you gain sufficient proficiency I shall be the first to know it and then we shall lose no time in making Barsoom safe for posterity."

The old man was far from achieving hatred of himself. However, his plan was an excellent one, both for himself and for me. It assured us immortality-we might live for ever and always with strong, healthy, young bodies. The outlook was alluring-and what a wonderful position it placed me in. If the old man could be assured of my loyalty because of self-interest, similarly might I depend upon his loyalty; for he could not afford to antagonize the one creature in the world who could assure him immortality, or withhold it from him. For the first time since I had entered his establishment I felt safe.

As soon as I had left him I went directly to Valla Dia's apartment, for I wanted to tell her his wonderful news. In the weeks that had passed since her resurrection I had seen much of her and in our daily intercourse there had been revealed to me little by little the wondrous beauties of her soul, until at last I no longer saw the hideous, disfigured face of Xaxa when I looked upon her, but the eyes of my heart penetrated deeper to the loveliness that lay within that sweet mind. She had become my confidante, as I was hers, and this association constituted the one great pleasure of my existence upon Barsoom.

Her congratulations, when I told her of what had come to me, were very sincere and lovely. She said that she hoped I would use this great power of mine to do good in the world. I assured her that I would and that among the first things that I should demand of Ras Thavas was that he should give Valla Dia a beautiful body; but she shook her head.

"No, my friend," she said, "if I may not have my own body this old one of Xaxa's is quite as good for me as another. Without my own body I should not care to return to my native country; while were Ras Thavas to give me the beautiful body of another, I should always be in danger of the covetousness of his clients, any one of whom might see and desire to purchase it, leaving to me her old husk, conceivably one quite terribly diseased or maimed. No, my friend, I am satisfied with the body of Xaxa, unless I may again possess my own, for Xaxa at least bequeathed me a tough and healthy envelope, however ugly it may be; and for what do looks count here? You, alone, are my friend-that I have your friendship is enough. You admire me for what I am, not for what I look like, so let us leave well enough alone."

"If you could regain your own body and return to your native country, you would like that?" I demanded.

"Oh, do not say it!" she cried. "The simple thought of it drives me mad with longing. I must not harbour so hopeless a dream that at best may only tantalize me into greater abhorrence of my lot."

"Do not say that it is hopeless," I urged. "Death, only, renders hope futile."

"You mean to be kind," she said, "but you are only hurting me. There can be no hope."

"May I hope for you, then?" I asked. "For I surely see a way; however slight a possibility for success it may have, still, it is a way."

She shook her head. "There is no way," she said, with finality. "No more will Duhor know me."

"Duhor?" I repeated. "Your-someone you care for very much?"

"I care for Duhor very much," she answered with a smile, "but Duhor is not someone-Duhor is my home, the country of my ancestors."

"How came you to leave Duhor?" I asked. "You have never told me, Valla Dia."

"It was because of the ruthlessness of Jal Had, Prince of Amhor," she replied.

"Hereditary enemies were Duhor and Amhor; but Jal Had came disguised into the city of Duhor, having heard, they say, of the great beauty attributed to the only daughter of Kor San, Jeddak of Duhor, and when he had seen her he determined to possess her. Returning to Amhor he sent ambassadors to the court of Kor San to sue for the hand of the Princess of Duhor; but Kor San, who had no son, had determined to wed his daughter to one of his own Jeds, that the son of this union, with the blood of Kor San in his veins, might rule over the people of Duhor; and so the offer of Jal Had was declined.

"This so incensed the Amhorian that he equipped a great fleet and set forth to conquer Duhor and take by force that which he could not win by honorable methods. Duhor was, at that time, at war with Helium and all her forces were far afield in the south, with the exception of a small army that had been left behind to guard the city. Jal Had, therefore, could not have selected a more propitious time for an attack. Duhor fell, and while his troops were looting the fair city Jal Had, with a picked force, sacked the palace of the Jeddak and searched for the princess; but the princess had no mind to go back with him as Princess of Amhor. From the moment that the vanguard of the Amhorian fleet was seen in the sky she had known, with the others of the city, the purpose for which they came, and so she used her head to defeat that purpose.

"There was in her retinue a cosmetologist whose duty it was to preserve the lustrous beauty of the princess' hair and skin and prepare her for public audiences, for fetes and for the daily intercourse of the court. He was a master of his art; he could render the ugly pleasant to look upon, he could make the plain lovely, and he could make the lovely radiant. She called him quickly to her and commanded him to make the radiant ugly, and when he had done with her none might guess that she was the Princess of Duhor, so deftly had he wrought with his pigments and his tiny brushes.

"When Jal Had could not find the princess within the palace, and no amount of threat or torture could force a statement of her whereabouts from the loyal lips of her people, the Amhorian ordered that every woman within the palace be seized and taken to Amhor; there to be held as hostages until the Princess of Duhor should be delivered to him in marriage. We were, therefore, all seized and placed upon an Amhorian war ship which was sent back to Amhor ahead of the balance of the fleet, which remained to complete the sacking of Duhor.

"When the ship, with its small convoy, had covered some four thousand of the five thousand haads that separate Duhor from Amhor, it was sighted by a fleet from Phundahl which immediately attacked. The convoying ships were destroyed or driven off and that which carried us was captured. We were taken to Phundahl where we were put upon the auction block and I fell to the bid of one of Ras Thavas' agents. The rest you know."
