He turned suddenly upon me with a faint suggestion of a smile and dove headlong into what was to prove an intensive course of instruction in the Barsoomian language. It was long after dark before he permitted me to retire for the night, conducting me himself to a large apartment, the same in which I had found my new harness, where he pointed out a pile of rich sleeping silks and furs, bid me a Barsoomian good night and left me, locking the door after him upon the outside, and leaving me to guess whether I were more guest or prisoner.

Chapter 3 PREFERMENT

Three weeks passed rapidly. I had mastered enough of the Barsoomian tongue to enable me to converse with my host in a reasonably satisfactory manner, and I was also progressing slowly in the mastery of the written language of his nation, which is different, of course, from the written language of all other Barsoomian nations, though the spoken language of all is identical. In these three weeks I had learned much of the strange place in which I was half guest and half prisoner and of my remarkable host-jailer, Ras Thavas, the old surgeon of Toonol, whom I had accompanied almost constantly day after day until gradually there had unfolded before my astounded faculties an understanding of the purposes of the institution over which he ruled and in which he laboured practically alone; for the slaves and attendants that served him were but hewers of wood and carriers of water. It was his brain alone and his skill that directed the sometimes beneficent, the sometimes malevolent, but always marvellous activities of his life's work.

Ras Thavas himself was as remarkable as the things he accomplished. He was never intentionally cruel; he was not, I am sure, intentionally wicked. He was guilty of the most diabolical cruelties and the basest of crimes; yet in the next moment he might perform a deed that if duplicated upon Earth would have raised him to the highest pinnacle of man's esteem. Though I know that I am safe in saying that he was never prompted to a cruel or criminal act by base motives, neither was he ever urged to a humanitarian one by high motives. He had a purely scientific mind entirely devoid of the cloying influences of sentiment, of which he possessed none. His was a practical mind, as evidenced by the enormous fees he demanded for his professional services; yet I know that he would not operate for money alone and I have seen him devote days to the study of a scientific problem the solution of which could add nothing to his wealth, while the quarters that he furnished his waiting clients were overflowing with wealthy patrons waiting to pour money into his coffers.

His treatment of me was based entirely upon scientific requirements. I offered a problem. I was either, quite evidently, not a Barsoomian at all, or I was of a species of which he had no knowledge. It therefore best suited the purposes of science that I be preserved and studied. I knew much about my own planet. It pleased Ras Thavas' scientific mind to milk me of all I knew in the hope that he might derive some suggestion that would solve one of the Barsoomian scientific riddles that still baffle their savants; but he was compelled to admit that in this respect I was a total loss, not alone because I was densely ignorant upon practically all scientific subjects, but because the learned sciences on Earth have not advanced even to the swaddling-clothes stage as compared with the remarkable progress of corresponding activities on Mars. Yet he kept me by him, training me in many of the minor duties of his vast laboratory. I was entrusted with the formula of the "embalming fluid" and taught how to withdraw a subject's blood and replace it with this marvellous preservative that arrests decay without altering in the minutest detail the nerve or tissue structure of the body. I learned also the secret of the few drops of solution which, added to the rewarmed blood before it is returned to the veins of the subject revitalizes the latter and restores to normal and healthy activity each and every organ of the body.

He told me once why he had permitted me to learn these things that he had kept a secret from all others, and why he kept me with him at all times in preference to any of the numerous individuals of his own race that served him and me in lesser capacities both day and night.

"Vad Varo," he said, using the Barsoomian name that he had given me because he insisted that my own name was meaningless and impractical, "for many years I have needed an assistant, but heretofore I have never felt that I had discovered one who might work here for me wholeheartedly and disinterestedly without ever having reason to go elsewhere or to divulge my secrets to others. You, in all Barsoom, are unique—you have no other friend or acquaintance than myself. Were you to leave we you would find yourself in a world of enemies, for all are suspicious of a stranger. You would not survive a dozen dawns and you would be cold and hungry and miserable—a wretched outcast in a hostile world. Here you have every luxury that the mind of man can devise or the hand of man produce, and you are occupied with work of such engrossing interest that your every hour must be fruitful of unparalleled satisfaction. There is no selfish reason, therefore, why you should leave me and there is every reason why you should remain. I expect no loyalty other than that which may be prompted by egoism. You make an ideal assistant, not only for the reasons I have just given you, but because you are intelligent and quick-witted, and now I have decided, after observing you carefully for a sufficient time, that you can serve me in yet another capacity—that of personal bodyguard.

"You may have noticed that I alone of all those connected with my laboratory am armed. This is unusual upon Barsoom, where people of all classes, and all ages and both sexes habitually go unarmed. But many of these people I could not trust armed as they would slay me; and were I to give arms to those whom I might trust, who knows but that the others would obtain possession of them and slay me, or even those whom I had trusted turn against me, for there is not one who might not wish to go forth from this place back among his own people—only you, Vad Varo, for there is no other place for you to go. So I have decided to give you weapons.

"You saved my life once. A similar opportunity might again present itself. I know that being a reasoning and reasonable creature, you will not slay me, for you have nothing to gain and everything to lose by my death, which would leave you friendless and unprotected in a world of strangers where assassination is the order of society and natural death one of the rarest of phenomena. Here are your arms." He stepped to a cabinet which he unlocked, displaying an assortment of weapons, and selected for me a long-sword, a shortsword, a pistol and a dagger.

"You seem sure of my loyalty, Ras Thavas," I said.

He shrugged his shoulders. "I am only sure that I know perfectly where your interests lie—sentimentalists have words: love, loyalty, friendship, enmity, jealousy, hate, a thousand others; a waste of words —one word defines them all: self-interest. All men of intelligence realize this. They analyse an individual and by his predilections and his needs they classify him as friend or foe, leaving to the weak-minded idiots who like to be deceived the drooling drivel of sentiment."

I smiled as I buckled my weapons to my harness, but I held my peace. Nothing could be gained by arguing with the man and, too, I felt quite sure that in any purely academic controversy I should get the worst of it; but many of the matters of which he had spoken had aroused my curiosity and one had reawakened in my mind a matter to which I had given considerable thought.
