“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 this 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 confidant, 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.
