The Master Mind of Mars

Edgar Rice Burroughs

Chapter 1 A LETTER

HELIUM, June 8th, 1925

MY DEAR MR. BURROUGHS:

It was in the Fall of nineteen seventeen at an officers' training camp that I first became acquainted with John Carter, War Lord of Barsoom, through the pages of your novel "A Princess of Mars." The story made a profound impression upon me and while my better judgment assured me that it was but a highly imaginative piece of fiction, a suggestion of the verity of it pervaded my inner consciousness to such an extent that I found myself dreaming of Mars and John Carter, of Dejah Thoris, of Tars Tarkas and of Woola as if they had been entities of my own experience rather than the figments of your imagination.

It is true that in those days of strenuous preparation there was little time for dreaming, yet there were brief moments before sleep claimed me at night and these were my dreams. Such dreams! Always of Mars, and during my waking hours at night my eyes always sought out the Red Planet when he was above the horizon and clung there seeking a solution of the seemingly unfathomable riddle he has presented to the Earthman for ages.

Perhaps the thing became an obsession. I know it clung to me all during my training camp days, and at night, on the deck of the transport, I would he on my back gazing up into the red eye of the god of battle— my god—and wishing that, like John Carter, I might be drawn across the great void to the haven of my desire.

And then came the hideous days and nights in the trenches—the rats, the vermin, the mud—with an occasional glorious break in the monotony when we were ordered over the top. I loved it then and I loved the bursting shells, the mad, wild chaos of the thundering guns, but the rats and the vermin and the mud—God! how I hated them. It sounds like boasting, I know, and I am sorry; but I wanted to write you just the truth about myself. I think you will understand.

And it may account for much that happened afterwards.

There came at last to me what had come to so many others upon those bloody fields. It came within the week that I had received my first promotion and my captaincy, of which I was greatly proud, though humbly so; realizing as I did my youth, the great responsibility that it placed upon me as well as the opportunities it offered, not only in service to my country but, in a personal way, to the men of my command. We had advanced a matter of two kilometers and with a small detachment I was holding a very advanced position when I received orders to fall back to the new line. That is the last that I remember until I regained consciousness after dark. A shell must have burst among us. What became of my men I never knew. It was cold and very dark when I awoke and at first, for an instant, I was quite comfortable—before I was fully conscious, I imagine—and then I commenced to feel pain. It grew until it seemed unbearable. It was in my legs. I reached down to feel them, but my hand recoiled from what it found, and when I tried to move my legs I discovered that I was dead from the waist down. Then the moon came out from behind a cloud and I saw that I lay within a shell hole and that I was not alone—the dead were all about me.

It was a long time before I found the moral courage and the physical strength to draw myself up upon one elbow that I might view the havoc that had been done me.

One look was enough, I sank back in an agony of mental and physical anguish—my legs had been blown away from midway between the hips and knees. For some reason I was not bleeding excessively, yet I know that I had lost a great deal of blood and that I was gradually losing enough to put me out of my misery in a short time if I were not soon found; and as I lay there on my back, tortured with pain, I prayed that they would not come in time, for I shrank more from the thought of going maimed through life than I shrank from the thought of death.

Then my eyes suddenly focussed upon the bright red eye of Mars and there surged through me a sudden wave of hope. I stretched out my arms towards Mars, I did not seem to question or to doubt for an instant as I prayed to the god of my vocation to reach forth and succour me. I knew that he would do it, my faith was complete, and yet so great was the mental effort that I made to throw off the hideous bonds of my mutilated flesh that I felt a momentary qualm of nausea and then a sharp click as of the snapping of a steel wire, and suddenly I stood naked upon two good legs looking down upon the bloody, distorted thing that had been I. Just for an instant did I stand thus before I turned my eyes aloft again to my star of destiny and with outstretched arms stand there in the cold of that French night—waiting.

Suddenly I felt myself drawn with the speed of thought through the trackless wastes of interplanetary space. There was an instant of extreme cold and utter darkness, then—But the rest is in the manuscript that, with the aid of one greater than either of us, I have found the means to transmit to you with this letter. You and a few others of the chosen will believe in it—for the rest it matters not as yet.

The time will come—but why tell you what you already know?

My salutations and my congratulations—the latter on your good fortune in having been chosen as the medium through which Earthmen shall become better acquainted with the manners and customs of Barsoom, against the time that they shall pass through space as easily as John Carter, and visit the scenes that he has described to them through you, as have I.

Your sincere friend, ULYSSES PAXTON, Late Captain,—th Inf., U.S. Army.

Chapter 2 THE HOUSE OF THE DEAD

I must have closed my eyes involuntarily during the transition for when I opened them I was lying flat on my back gazing up into a brilliant, sun-lit sky, while standing a few feet from me and looking down upon me with the most mystified expression was as strange a looking individual as my eyes ever had rested upon.

He appeared to be quite an old man, for he was wrinkled and withered beyond description. His limbs were emaciated; his ribs showed distinctly beneath his shrunken hide; his cranium was large and well developed, which, in conjunction with his wasted limbs and torso, lent him the appearance of top heaviness, as though he had a head beyond all proportion to his body, which was, I am sure, really not the case.

As he stared down upon me through enormous, many lensed spectacles I found the opportunity to examine him as minutely in return. He was, perhaps, five feet five in height, though doubtless he had been taller in youth, since he was somewhat bent; he was naked except for some rather plain and well-worn leather harness which supported his weapons and pocket pouches, and one great ornament a collar, jewel studded, that he wore around his scraggy neck—such a collar as a dowager empress of pork or real estate might barter her soul for, if she had one. His skin was red, his scant locks grey. As he looked at me his puzzled expression increased in intensity, he grasped his chin between the thumb and fingers of his left hand and slowly raising his right hand he scratched his head most deliberately. Then he spoke to me, but in a language I did not understand.

At his first words I sat up and shook my head. Then I looked about me. I was seated upon a crimson sward within a high walled enclosure, at least two, and possibly three, sides of which were formed by the outer walls of a structure that in some respects resembled more closely a feudal castle of Europe than any familiar form of architecture that comes to my mind. The facade presented to my view was ornately carved and of most irregular design, the roof line being so broken as to almost suggest a ruin, and yet the whole seemed harmonious and not without beauty. Within the enclosure grew a number of trees and shrubs, all weirdly strange and all, or almost all, profusely flowering. About them wound walks of coloured pebbles among which scintillated what appeared to be rare and beautiful gems, so lovely were the strange, unearthly rays that leaped and played in the sunshine.

The old man spoke again, peremptorily this time, as though repeating a command that had been ignored, but again I shook my head. Then he laid a hand upon one of his two swords, but as he drew the weapon I leaped to my feet, with such remarkable results that I cannot even now say which of us was the more surprised. I must have sailed ten feet into the air and back about twenty feet from where I had been sitting; then I was sure that I was upon Mars (not that I had for one instant doubted it), for the effects of the lesser gravity, the colour of the sward and the skin-hue of the red Martians I had seen described in the manuscripts of John Carter, those marvellous and as yet unappreciated contributions to the scientific literature of a world. There could be no doubt of it, I stood upon the soil of the Red Planet, I had come to the world of my dreams—to Barsoom.

So startled was the old man by my agility that he jumped a bit himself, though doubtless involuntarily, but, however, with certain results. His spectacles tumbled from his nose to the sward, and then it was that I discovered that the pitiful old wretch was practically blind when deprived of these artificial aids to vision, for he got to his knees and commenced to grope frantically for the lost glasses, as though his very life depended upon finding them in the instant.

Possibly he thought that I might take advantage of his helplessness and slay him. Though the spectacles were enormous and lay within a couple of feet of him he could not find them, his hands, seemingly afflicted by that strange perversity that sometimes confounds our simplest acts, passing all about the lost object of their search, yet never once coming in contact with it.

As I stood watching his futile efforts and considering the advisability of restoring to him the means that would enable him more readily to find my heart with his sword point, I became aware that another had entered the enclosure.

Looking towards the building I saw a large red-man running rapidly towards the little old man of the spectacles. The newcomer was quite naked, he carried a club in one hand, and there was upon his face such an expression as unquestionably boded ill for the helpless husk of humanity grovelling, mole-like, for its lost spectacles.

My first impulse was to remain neutral in an affair that it seemed could not possibly concern me and of which I had no slightest knowledge upon which to base a predilection towards either of the parties involved; but a second glance at the face of the club-bearer aroused a question as to whether it might not concern me after all.

There was that in the expression upon the man's face that betokened either an inherent savageness of disposition or a maniacal cast of mind which might turn his evidently murderous attentions upon me after he had dispatched his elderly victim, while, in outward appearance at least, the latter was a sane and relatively harmless individual. It is true that his move to draw his sword against me was not indicative of a friendly disposition towards me, but at least, if there were any choice, he seemed the lesser of two evils.

He was still groping for his spectacles and the naked man was almost upon him as I reached the decision to cast my lot upon the side of the old man. I was twenty feet away, naked and unarmed, but to cover the distance with my Earthly muscles required but an instant, and a naked sword lay by the old man's side where he had discarded it the better to search for his spectacles. So it was that I faced the attacker at the instant that he came within striking distance of his victim, and the blow which had been intended for another was aimed at me. I side-stepped it and then I learned that the greater agility of my Earthly muscles had its disadvantages as well as its advantages, for, indeed, I had to learn to walk at the very instant that I had to learn to fight with a new weapon against a maniac armed with a bludgeon, or at least, so I assumed him to be and I think that it is not strange that I should have done so, what with his frightful show of rage and the terrible expression upon his face.

As I stumbled about endeavouring to accustom myself to the new conditions, I found that instead of offering any serious opposition to my antagonist I was hard put to it to escape death at his hands, so often did I stumble and fall sprawling upon the scarlet sward; so that the duel from its inception became but a series of efforts, upon his part to reach and crush me with his great club, and upon mine to dodge and elude him. It was mortifying but it is the truth.

However, this did not last indefinitely, for soon I learned, and quickly too under the exigencies of the situation, to command my muscles, and then I stood my ground and when he aimed a blow at me, and I had dodged it, I touched him with my point and brought blood along with a savage roar of pain. He went more cautiously then, and taking advantage of the change I pressed him so that he fell back. The effect upon me was magical, giving me new confidence, so that I set upon him in good earnest, thrusting and cutting until I had him bleeding in a half-dozen places, yet taking good care to avoid his mighty swings, any one of which would have felled an ox.

In my attempts to elude him in the beginning of the duel we had crossed the enclosure and were now fighting at a considerable distance from the point of our first meeting. It now happened that I stood facing towards that point at the moment that the old man regained his spectacles, which he quickly adjusted to his eyes. Immediately he looked about until he discovered us, whereupon he commenced to yell excitedly at us at the same time running in our direction and drawing his short-sword as he ran. The red-man was pressing me hard, but I had gained almost complete control of myself, and fearing that I was soon to have two antagonists instead of one I set upon him with redoubled intensity. He missed me by the fraction of an inch, the wind in the wake of his bludgeon fanning my scalp, but he left an opening into which I stepped, running my word fairly through his heart. At least I thought that I had pierced his heart but I had forgotten what I had once read in one of John Carter's manuscripts to the effect that all the Martian internal organs are not disposed identically with those of Earthmen. However, the immediate results were quite as satisfactory as though I had found his heart for the wound was sufficiently grievous to place him hors de combat, and at that instant the old gentleman arrived. He found me ready, but I had mistaken his intentions. He made no unfriendly gestures with his weapon, but seemed to be trying to convince me that he had no intention of harming me. He was very excited and apparently tremendously annoyed that I could not understand him, and perplexed, too. He hopped about screaming strange sentences at me that bore the tones of peremptory commands, rabid invective and impotent rage. But the fact that he had returned his sword to its scabbard had greater significance than all his jabbering, and when he ceased to yell at me and commenced to talk in a sort of pantomime I realized that he was making overtures of peace if not of friendship, so I lowered my point and bowed. It was all that I could think of to assure him that I had no immediate intention of spitting him.

He seemed satisfied and at once turned his attention to the fallen man. He examined his pulse and listened to his heart, then, nodding his head, he arose and taking a whistle from one of his pocket pouches sounded a single loud blast.

There emerged immediately from one of the surrounding buildings a score of naked red-men who came running towards us. None was armed. To these he issued a few curt orders, whereupon they gathered the fallen one in their arms and bore him off. Then the old man started towards the building, motioning me to accompany him. There seemed nothing else for me to do but obey. Wherever I might be upon Mars, the chances were a million to one that I would be among enemies; and so I was as well off here as elsewhere and must depend upon my own resourcefulness, skill and agility to make my way upon the Red Planet.

The old man led me into a small chamber from which opened numerous doors, through one of which they were just bearing my late antagonist. We followed into a large, brilliantly lighted chamber wherein there burst upon my astounded vision the most gruesome scene that I ever had beheld. Rows upon rows of tables arranged in parallel lines filled the room and with few exceptions each table bore a similar grisly burden, a partially dismembered or otherwise mutilated human corpse. Above each table was a shelf bearing containers of various sizes and shapes, while from the bottom of the shelf depended numerous surgical instruments, suggesting that my entrance upon Barsoom was to be through a gigantic medical college.

At a word from the old man, those who bore the Barsoomian I had wounded laid him upon an empty table and left the apartment. Whereupon my host if so I may call him, for certainly he was not as yet my captor, motioned me forward. While he conversed in ordinary tones, he made two incisions in the body of my late antagonist; one, I imagine, in a large vein and one in an artery, to which he deftly attached the ends of two tubes, one of which was connected with an empty glass receptacle and the other with a similar receptacle filled with a colourless, transparent liquid resembling clear water. The connections made, the old gentleman pressed a button controlling a small motor, whereupon the victim's blood was pumped into the empty jar while the contents of the other was forced into the emptying veins and arteries.

The tones and gestures of the old man as he addressed me during this operation convinced me that he was explaining in detail the method and purpose of what was transpiring, but as I understood no word of all he said I was as much in the dark when he had completed his discourse as I was before he started it, though what I had seen made it appear reasonable to believe that I was witnessing an ordinary Barsoomian embalming. Having removed the tubes the old man closed the openings he had made by covering them with bits of what appeared to be heavy adhesive tape and then motioned me to follow him. We went from room to room, in each of which were the same gruesome exhibits. At many of the bodies the old man paused to make a brief examination or to refer to what appeared to be a record of the case, that hung upon a hook at the head of each of the tables.

From the last of the chambers we visited upon the first floor my host led me up an inclined runway to the second floor where there were rooms similar to those below, but here the tables bore whole rather than mutilated bodies, all of which were patched in various places with adhesive tape. As we were passing among the bodies in one of these rooms a Barsoomian girl, whom I took to be a servant or slave, entered and addressed the old man, whereupon he signed me to follow him and together we descended another runway to the first floor of another building.

Here, in a large, gorgeously decorated and sumptuously furnished apartment an elderly red-woman awaited us. She appeared to be quite old and her face was terribly disfigured as by some injury. Her trappings were magnificent and she was attended by a score of women and armed warriors, suggesting that she was a person of some consequence, but the little old man treated her quite brusquely, as I could see, quite to the horror of her attendants.

Their conversation was lengthy and at the conclusion of it, at the direction of the woman, one of her male escort advanced and opening a pocket pouch at his side withdrew a handful of what appeared to me to be Martian coins. A quantity of these he counted out and handed to the little old man, who then beckoned the woman to follow him, a gesture which included me. Several of her women and guard started to accompany us, but these the old man waved back peremptorily; whereupon there ensued a heated discussion between the woman and one of her warriors on one side and the old man on the other, which terminated in his proffering the return of the woman's money with a disgusted air. This seemed to settle the argument, for she refused the coins, spoke briefly to her people and accompanied the old man and myself alone.

He led the way to the second floor and to a chamber which I had not previously visited. It closely resembled the others except that all the bodies therein were of young women, many of them of great beauty. Following closely at the heels of the old man the woman inspected the gruesome exhibit with painstaking care.

Thrice she passed slowly among the tables examining their ghastly burdens. Each time she paused longest before a certain one which bore the figure of the most beautiful creature I had ever looked upon; then she returned the fourth time to it and stood looking long and earnestly into the dead face. For awhile she stood there talking with the old man, apparently asking innumerable questions, to which he returned quick, brusque replies, then she indicated the body with a gesture and nodded assent to the withered keeper of this ghastly exhibit.

Immediately the old fellow sounded a blast upon his whistle, summoning a number of servants to whom he issued brief instructions, after which he led us to another chamber, a smaller one in which were several empty tables similar to those upon which the corpses lay in adjoining rooms. Two female slaves or attendants were in this room and at a word from their master they removed the trappings from the old woman, unloosed her hair and helped her to one of the tables. Here she was thoroughly sprayed with what I presume was an antiseptic solution of some nature, carefully dried and removed to another table, at a distance of about twenty inches from which stood a second parallel table.

Now the door of the chamber swung open and two attendants appeared bearing the body of the beautiful girl we had seen in the adjoining room. This they deposited upon the table the old woman had just quitted and as she had been sprayed so was the corpse, after which it was transferred to the table beside that on which she lay. The little old man now made two incisions in the body of the old woman, just as he had in the body of the red-man who had fallen to my sword; her blood was drawn from her veins and the clear liquid pumped into them, life left her and she lay upon the polished ersite slab that formed the table top, as much a corpse as the poor, beautiful, dead creature at her side.

The little old man, who had removed the harness down to his waist and been thoroughly sprayed, now selected a sharp knife from among the instruments above the table and removed the old woman's scalp, following the hair line entirely around her head. In a similar manner he then removed the scalp from the corpse of the young woman, after which, by means of a tiny circular saw attached to the end of a flexible, revolving shaft he sawed through the skull of each, following the line exposed by the removal of the scalps. This and the balance of the marvellous operation was so skilfully performed as to baffle description.

Suffice it to say that at the end of four hours he had transferred the brain of each woman to the brain pan of the other, deftly connected the severed nerves and ganglia, replaced the skulls and scalps and bound both heads securely with his peculiar adhesive tape, which was not only antiseptic and healing but anaesthetic, locally, as well.

He now reheated the blood that he had withdrawn from the body of the old woman, adding a few drops of some clear chemical solution, withdrew the liquid from the veins of the beautiful corpse, replacing it with the blood of the old woman and simultaneously administering a hypodermic injection.

During the entire operation he had not spoken a word. Now he issued a few instructions in his curt manner to his assistants, motioned me to follow him, and left the room. He led me to a distant part of the building or series of buildings that composed the whole, ushered me into a luxurious apartment, opened the door to a Barsoomian bath and left me in the hands of trained servants.

Refreshed and rested I left the bath after an hour of relaxation to find harness and trappings awaiting me in the adjoining chamber. Though plain, they were of good material, but there were no weapons with them.

Naturally I had been thinking much upon the strange things I had witnessed since my advent upon Mars, but what puzzled me most lay in the seemingly inexplicable act of the old woman in paying my host what was evidently a considerable sum to murder her and transfer to the inside of her skull the brain of a corpse. Was it the outcome of some horrible religious fanaticism, or was there an explanation that my Earthly mind could not grasp?

I had reached no decision in the matter when I was summoned to follow a slave to another and near-by apartment where I found my host awaiting me before a table loaded with delicious foods, to which, it is needless to say, I did ample justice after my long fast and longer weeks of rough army fare.

During the meal my host attempted to converse with me, but, naturally, the effort was fruitless of results. He waxed quite excited at times and upon three distinct occasions laid his hand upon one of his swords when I failed to comprehend what he was saying to me, an action which resulted in a growing conviction upon my part that he was partially demented; but he evinced sufficient self-control in each instance to avert a catastrophe for one of us.

The meal over he sat for a long time in deep meditation, then a sudden resolution seemed to possess him. 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. While partially explained by some of his remarks I still wondered why the red-man from whom I had rescued him had seemed so venomously bent upon slaying him the day of my advent upon Barsoom, and so, as we sat chatting after our evening meal, I asked him.

"A sentimentalist," he said. "A sentimentalist of the most pronounced type. Why that fellow hated me with a venom absolutely unbelievable by any of the reactions of a trained, analytical mind such as mine; but having witnessed his reactions I become cognizant of a state of mind that I cannot of myself even imagine. Consider the facts. He was the victim of assassination—a young warrior in the prime of life, possessing a handsome face and a splendid physique. One of my agents paid his relatives a satisfactory sum for the corpse and brought it to me. It is thus that I obtain practically all of my material. I treated it in the manner with which you are familiar. For a year the body lay in the laboratory, there being no occasion during that time that I had use for it; but eventually a rich client came, a not overly prepossessing man of considerable years. He had fallen desperately in love with a young woman who was attended by many handsome suitors. My client had more money than any of them, more brains, more experience, but he lacked the one thing that each of the others had that always weighs heavily with the undeveloped, unreasoning, sentiment-ridden minds of young females—good looks."

"Now 378-J-493811-P had what my client lacked and could afford to purchase."

Quickly we reached an agreement as to price and I transferred the brain of my rich client to the head of 378-J-493811-P and my client went away and for all I know won the hand of the beautiful moron; and 378-J-493811-P might have rested on indefinitely upon his ersite slab until I needed him or a part of him in my work, had I not, merely by chance, selected him for resurgence because of an existing need for another male slave.

"Mind you now, the man had been murdered. He was dead. I bought and paid for the corpse and all there was in it. He might have lain dead forever upon one of my ersite slabs had I not breathed new life into his dead veins. Did he have the brains to view the transaction in a wise and dispassionate manner? He did not."

His sentimental reactions caused him to reproach me because I had given him another body, though it seemed to me that, looking at the matter from a standpoint of sentiment, if one must, he should have considered me as a benefactor for having given him life again In a perfectly healthy, if somewhat used, body.

"He had spoken to me upon the subject several times, begging me to restore his body to him, a thing of which, of course, as I explained to him, was utterly out of the question unless chance happened to bring to my laboratory the corpse of the client who had purchased his carcass— a contingency quite beyond the pale of possibility for one as wealthy as my client. The fellow even suggested that I permit him to go forth and assassinate my client bringing the body back that I might reverse the operation and restore his body to his brain. When I refused to divulge the name of the present possessor of his body he grew sulky, but until the very hour of your arrival, when he attacked me, I did not suspect the depth of his hate complex.

"Sentiment is indeed a bar to all progress. We of Toonol are probably less subject to its vagaries than most other nations upon Barsoom, but yet most of my fellow countrymen are victims of it in varying degrees. It has its rewards and compensations, however. Without it we could preserve no stable form of government and the Phundahlians, or some other people, would overrun and conquer us; but enough of our lower classes have sentiment to a sufficient degree to give them loyalty to the Jeddak of Toonol and the upper classes are brainy enough to know that it is to their own best interests to keep him upon his throne.

"The Phundahlians, upon the other hand, are egregious sentimentalists, filled with crass stupidities and superstitions, slaves to every variety of brain withering conceit. Why the very fact that they keep the old termagant, Xaxa, on the throne brands them with their stupid idiocy. She is an ignorant, arrogant, selfish, stupid, cruel virago, yet the Phundahlians would fight and die for her because her father was Jeddak of Phundahl. She taxes them until they can scarce stagger beneath their burden, she misrules them, exploits them, betrays them, and they fall down and worship at her feet. Why? Because her father was Jeddak of Phundahl and his father before him and so on back into antiquity; because they are ruled by sentiment rather than reason; because their wicked rulers play upon this sentiment.

"She had nothing to recommend her to a sane person—not even beauty. You know, you saw her."

"I saw her?" I demanded.

"You assisted me the day that we gave her old brain a new casket—the day you arrived from what you call your Earth."

"She! That old woman was Jeddara of Phundahl?"

"That was Xaxa," he assured me.

"Why, you did not accord her the treatment that one of the Earth would suppose would be accorded a ruler, and so I had no idea that she was more than a rich old woman."

"I am Ras Thavas," said the old man. "Why should I incline the head to any other? In my world nothing counts but brain and in that respect and without egotism, I may say that I acknowledge no superior."

"Then you are not without sentiment," I said, smiling. "You acknowledge pride in your intellect!" "It is not pride," he said, patiently, for him, "it is merely a fact that I state. A fact that I should have no difficulty in proving. In all probability I have the most highly developed and perfectly functioning mind among all the learned men of my acquaintance, and reason indicates that this fact also suggests that I possess the most highly developed and perfectly functioning mind upon Barsoom. From what I know of Earth and from what I have seen of you, I am convinced that there is no mind upon your planet that may even faintly approximate in power that which I have developed during a thousand years of active study and research. Rasoom (Mercury) or Cosoom (Venus) may possibly support intelligences equal to or even greater than mine. While we have made some study of their thought waves, our instruments are not yet sufficiently developed to more than suggest that they are of extreme refinement, power and flexibility."

"And what of the girl whose body you gave to the Jeddara?" I asked, irrelevantly, for my mind could not efface the memory of that sweet body that must, indeed, have possessed an equally sweet and fine brain.

"Merely a subject! Merely a subject!" he replied with a wave of his hand.

"What will become of her?' I insisted.

"What difference does it make?" he demanded. "I bought her with a batch of prisoners of war. I do not even recall from what country my agent obtained them, or from whence they originated. Such matters are of no import."

"She was alive when you bought her?" I demanded.

"Yes. Why?"

"You-er-ah-killed her, then?"

"Killed her! No; I preserved her. That was some ten years ago. Why should I permit her to grow old and wrinkled? She would no longer have the same value then, would she? No, I preserved her. When Xaxa bought her she was just as fresh and young as the day she arrived. I kept her a long time. Many women looked at her and wanted her face and figure, but it took a Jeddara to afford her. She brought the highest price that I have ever been paid."

"Yes, I kept her a long time, but I knew that some day she would bring my price."

She was indeed beautiful and so sentiment has its uses—were it not for sentiment there would be no fools to support this work that I am doing, thus permitting me to carry on investigations of far greater merit. You would be surprised, I know, were I to tell you that I feel that I am almost upon the point of being able to produce rational human beings through the action upon certain chemical combinations of a group of rays probably entirely undiscovered by your scientists, if I am to judge by the paucity of your knowledge concerning such things."

"I would not be surprised," I assured him. "I would not be surprised by anything that you might accomplish."

Chapter 4 VALLA DIA

I lay awake a long time that night thinking of 4296-E-2631-H, the beautiful girl whose perfect body had been stolen to furnish a gorgeous setting for the cruel brain of a tyrant. It seemed such a horrid crime that I could not rid my mind of it and I think that contemplation of it sowed the first seed of my hatred and loathing for Ras Thavas. I could not conjure a creature so utterly devoid of bowels of compassion as to even consider for a moment the frightful ravishing of that sweet and lovely body for even the holiest of purposes, much less one that could have been induced to do so for filthy pelf.

So much did I think upon the girl that night that her image was the first to impinge upon my returning consciousness at dawn, and after I had eaten, Ras Thavas not having appeared, I went directly to the storage room where the poor thing was. Here she lay, identified only by a small panel, bearing a number: 4296-E-2631-H. The body of an old woman with a disfigured face lay before me in the rigid immobility of death; yet that was not the figure that I saw, but instead, a vision of radiant loveliness whose imprisoned soul lay dormant beneath those greying locks.

The creature here with the face and form of Xaxa was not Xaxa at all, for all that made the other what she was had been transferred to this cold corpse. How frightful would be the awakening, should awakening ever come! I shuddered to think of the horror that must overwhelm the girl when first she realized the horrid crime that had been perpetrated upon her. Who was she? What story lay locked in that dead and silent brain? What loves must have been hers whose beauty was so great and upon whose fair face had lain the indelible imprint of graciousness! Would Ras Thavas ever arouse her from this happy semblance of death? -far happier than any quickening ever could be for her. I shrank from the thought of her awakening and yet I longed to hear her speak, to know that that brain lived again, to learn her name, to listen to the story of this gentle life that had been so rudely snatched from its proper environment and so cruelly handled by the hand of Fate. And suppose she were awakened! Suppose she were awakened and that I—A hand was laid upon my shoulder and I turned to look into the face of Ras Thavas.

You seem interested in this subject," he said.

"I was wondering," I replied, "what the reaction this girl's brain would be were she to awaken to the discovery that she had become an old, disfigured woman."

He stroked his chin and eyed me narrowly. "An interesting experiment," he mused.

"I am gratified to discover that you are taking a scientific interest in the labours that I am carrying on. The psychological phases of my work I have, I must confess, rather neglected during the past hundred years or so, though I formerly gave them a great deal of attention. It would be interesting to observe and study several of these cases. This one, especially, might prove of value to you as an initial study, it being simple and regular. Later we will let you examine into a case where a man's brain has been transferred to a woman's skull, and a woman's brain to a man's. There are also the interesting cases where a portion of diseased or injured brain has been replaced by a portion of the brain from another subject, and, for experimental purposes alone, those human brains that have been transplanted to the craniums of beasts, and vice versa, offer tremendous opportunities for observation. I have in mind one case in which I transferred half the brain of an ape to the skull of a man, after having removed half of his brain, which I grafted upon the remaining part of the brain in the ape's skull. That was a matter of several years ago and I have often thought that I should like to recall these two subjects and note the results. I shall have to have a look at them—as I recall it they are in vault L-42-X, beneath building 4-J-21. We shall have to have a look at them someday soon—it has been years since I have been below. There must be some very interesting specimens there that have escaped my mind. But come! let us recall 4296-E-2631-H.

"No!" I exclaimed, laying a hand upon his arm. "It would be horrible."

He turned a surprised look upon me and then a nasty, sneering smile curled his lips. "Maudlin, sentimental fool!" he cried. "Who dare say no to me?"

I laid a hand upon the hilt of my long-sword and looked him steadily in the eye.

"Ras Thavas," I said, "you are master in your own house; but while I am your guest treat me with courtesy."

He returned my look for a moment but his eyes wavered. "I was hasty," he said.

"Let it pass." That, I let answer for an apology—really it was more than I had expected—but the event was not unfortunate. I think he treated me with far greater respect thereafter; but now he turned immediately to the slab bearing the mortal remains of 4296-E-2631-H.

"Prepare the subject for revivification," he said, "and make what study you can of all its reactions." With that he left the room.

I was now fairly adept at this work which I set about with some misgivings but with the assurance that I was doing right in obeying Ras Thavas while I remained a member of his entourage. The blood that had once flowed through the veins of the beautiful body that Ras Thavas had sold to Xaxa reposed in an hermetically sealed vessel upon the shelf above the corpse. As I had before done in other cases beneath the watchful eyes of the old surgeon I now did for the first time alone. The blood heated, the incisions made, the tubes attached and the few drops of life-giving solution added to the blood, I was now ready to restore life to that delicate brain that had lain dead for ten years. As my finger rested upon the little button that actuated the motor that was to send the revivifying liquid into those dormant veins, I experienced such a sensation as I imagined no mortal man has ever felt.

I had become master of life and death, and yet at this moment that I stood there upon the point of resurrecting the dead I felt more like a murderer than a saviour. I tried to view the procedure dispassionately through the cold eye of science, but I failed miserably. I could only see a stricken girl grieving for her lost beauties. With a muffled oath I turned away. I could not do it! And then, as though an outside force had seized upon me, my finger moved unerringly to the button and pressed it. I cannot explain it, unless upon the theory of dual mentality, which may explain many things. Perhaps my subjective mind directed the act. I do not know. Only I know that I did it, the motor started, the level of the blood in the container commenced gradually to lower.

Spell-bound, I stood watching. Presently the vessel was empty. I shut off the motor, removed the tubes, sealed the openings with tape. The red glow of life tinged the body, replacing the sallow, purplish hue of death. The breasts rose and fell regularly, the head turned slightly and the eyelids moved. A faint sigh issued from between the parting lips. For a long time there was no other sign of life, then, suddenly, the eyes opened. They were dull at first, but presently they commenced to fill with questioning wonderment. They rested on me and then passed on about that portion of the room that was visible from the position of the body. Then they came back to me and remained steadily fixed upon my countenance after having once surveyed me up and down. There was still the questioning in them, but there was no fear.

"Where am I?" she asked. The voice was that of an old woman—high and harsh. A startled expression filled her eyes. "What is the matter with me? What is wrong with my voice? What has happened?"

I laid a hand upon her forehead. "Don't bother about it now," I said, soothingly. "Wait until sometime when you are stronger. Then I will tell you."

She sat up. "I am strong," she said, and then her eyes swept her lower body and limbs and a look of utter horror crossed her face. "What has happened to me? In the name of my first ancestor, what has happened to me?"

The shrill, harsh voice grated upon me. It was the voice of Xaxa and Xaxa now must possess the sweet musical tones that alone would have harmonized with the beautiful face she had stolen. I tried to forget those strident notes and think only of the pulchritude of the envelope that had once graced the soul within this old and withered carcass.

She extended a hand and laid it gently upon mine. The act was beautiful, the movements graceful. The brain of the girl directed the muscles, but the old, rough vocal cords of Xaxa could give forth no sweeter notes. "Tell me, please!" she begged. There were tears in the old eyes, I'll venture for the first time in many years. "Tell me! You do not seem unkind."

And so I told her. She listened intently and when I was through she sighed.

"After all," she said, "it is not so dreadful, now that I really know. It is better than being dead." That made me glad that I had pressed the button. She was glad to be alive, even draped in the hideous carcass of Xaxa. I told her as much.

"You were so beautiful," I told her.

"And now I am so ugly?" I made no answer.

"After all, what difference does it make?" she inquired presently. "This old body cannot change me, or make me different from what I have always been. The good in me remains and whatever of sweetness and kindness, and I can be happy to be alive and perhaps to do some good. I was terrified at first, because I did not know what had happened to me. I thought that maybe I had contracted some terrible disease that had so altered me—that horrified me; but now that I know—pouf! what of it?"

"You are wonderful," I said. "Most women would have gone mad with the horror and grief of it—to lose such wondrous beauty as was yours— and you do not care."

"Oh, yes, I care, my friend," she corrected me, "but I do not care enough to ruin my life in all other respects because of it, or to cast a shadow upon the lives of those around me. I have had my beauty and enjoyed it. It is not an unalloyed happiness I can assure you. Men killed one another because of it; two great nations went to war because of it; and perhaps my father lost his throne or his life—I do not know, for I was captured by the enemy while the war still raged. It may be raging yet and men dying because I was too beautiful. No one will fight for me now, though," she added, with a rueful smile.

"Do you know how long you have been here?" I asked.

"Yes," she replied. "It was the day before yesterday that they brought me hither."

"It was ten years ago," I told her.

"Ten years! Impossible."

I pointed to the corpses around us. "You have lain like this for ten years," I explained. "There are subjects here who have lain thus for fifty, Ras Thavas tells me."

"Ten years! Ten years! What may not have happened in ten years! It is better thus. I should fear to go back now. I should not want to know that my father, my mother too, perhaps, were gone. It is better thus. Perhaps you will let me sleep again? May I not?"

"That remains with Ras Thavas," I replied; "but for a while I am to observe you."

"Observe me?"

"Study you—your reactions."

"Ah! and what good will that do?"

"It may do some good in the world."

"It may give this horrid Ras Thavas some new ideas for his torture chamber—some new scheme for coining money from the suffering of his victims," she said, her harsh voice saddened.

"Some of his works are good," I told her. "The money he makes permits him to maintain this wonderful establishment where he constantly carries on countless experiments. Many of his operations are beneficent. Yesterday a warrior was brought in whose arm was crushed beyond repair. Ras Thavas gave him a new arm. A demented child was brought. Ras Thavas gave her a new brain. The arm and the brain were taken from two who had met violent deaths. Through Ras Thavas they were permitted, after death, to give life and happiness to others."

She thought for a moment. "I am content," she said. "I only hope that you will always be the observer."

Presently Ras Thavas came and examined her. "A good subject," he said. He looked at the chart where I had made a very brief record following the other entries relative to the history of Case No. 4296-E-2631-H. Of course this is, naturally, a rather free translation of this particular identification number. The Barsoomians have no alphabet such as ours and their numbering system is quite different. The thirteen characters above were represented by four Toonolian characters, yet the meaning was quite the same—they represented, in contracted form, the case number, the room, the table and the building.

"The subject will be quartered near you where you may regularly observe it," continued Ras Thavas. "There is a chamber adjoining yours. I will see that it is unlocked. Take the subject there. When not under your observation, lock it in."

It was only another case to him.

I took the girl, if I may so call her, to her quarters. On the way I asked her her name, for it seemed to me an unnecessary discourtesy always to address her and refer to her as 4296-E-2631-H, and this I explained to her.

"It is considerate of you to think of that," she said, "but really that is all that I am here—just another subject for vivisection."

"You are more than that to me," I told her. "You are friendless and helpless. I want to be of service to you—to make your lot easier if I can."

"Thank you again," she said. "My name is Valla Dia, and yours?"

"Ras Thavas calls me Vad Varo," I told her.

But that is not your name?"

"My name is Ulysses Paxton."

"It is a strange name, unlike any that I have ever heard, but you are unlike any man I have ever seen—you do not seem Barsoomian. Your colour is unlike that of any race."

"I am not of Barsoom, but from Earth, the planet you sometimes call Jasoom. That is why I differ in appearance from any you have known before."

"Jasoom! There is another Jasoomian here whose fame has reached to the remotest comers of Barsoom, but I never have seen him."

"John Carter?" I asked.

"Yes, The War Lord. He was of Helium and my people were not friendly with those of Helium. I never could understand how he came here. And now there is another from Jasoom—how can it be? How did you cross the great void?"

I shook my head. "I cannot even guess," I told her.

"Jasoom must be peopled with wonderful men," she said. It was a pretty compliment.

"As Barsoom is with beautiful women," I replied.

She glanced down ruefully at her old and wrinkled body.

"I have seen the real you," I said gently.

"I hate to think of my face," she said. "I know it is a frightful thing."

"It is not you, remember that when you see it and do not feel too badly."

"Is it as bad as that?" she asked.

I did not reply. "Never mind," she said presently. "If I had not beauty of the soul, I was not beautiful, no matter how perfect my features may have been; but if I possessed beauty of soul then I have it now. So I can think beautiful thoughts and perform beautiful deeds and that, I think, is the real test of beauty, after all."

"And there is hope," I added, almost in a whisper.

"Hope? No, there is no hope, if what you mean to suggest is that I may some time regain my lost self. You have told me enough to convince me that that can never be."

"We will not speak of it," I said, "but we may think of it and sometimes thinking a great deal of a thing helps us to find a way to get it, if we want it badly enough."

"I do not want to hope," she said, "for it will but mean disappointment for me. I shall be happy as I am. Hoping, I should always be unhappy."

I had ordered food for her and after it was brought Ras Thavas sent for me and I left her, locking the door of her chamber as the old surgeon had instructed. I found Ras Thavas in his office, a small room which adjoined a very large one in which were a score of clerks arranging and classifying reports from various departments of the great laboratory. He arose as I entered.

"Come with me, Vad Varo," he directed. "We will have a look at the two cases in L-42-X, the two of which I spoke."

"The man with half a simian brain and the ape with a half human brain?" I asked.

He nodded and preceded me towards the runway that led to the vaults beneath the building. As we descended, the corridors and passageways indicated long disuse.

The floors were covered with an impalpable dust, long undisturbed; the tiny radium bulbs that faintly illuminated the sub-barsoomian depths were likewise coated. As we proceeded, we passed many doorways on either side, each marked with its descriptive hieroglyphic. Several of the openings had been tightly sealed with masonry. What gruesome secrets were hid within? At last we came to L-42-X. Here the bodies were arranged on shelves, several rows of which almost completely filled the room from floor to ceiling, except for a rectangular space in the centre of the chamber, which accommodated an ersite topped operating table with its array of surgical instruments, its motor and other laboratory equipment.

Ras Thavas searched out the subjects of his strange experiment and together we carried the human body to the table. While Ras Thavas attached the tubes I returned for the vessel of blood which reposed upon the same shelf with the corpse. The now familiar method of revivification was soon accomplished and presently we were watching the return of consciousness to the subject.

The man sat up and looked at us, then he cast a quick glance about the chamber; there was a savage light in his eyes as they returned to us. Slowly he backed from the table to the floor, keeping the former between us.

"We will not harm you," said Ras Thavas.

The man attempted to reply, but his words were unintelligible gibberish, then he shook his head and growled. Ras Thavas took a step towards him and the man dropped to all fours, his knuckles resting on the floor, and backed away, growling.

"Come!" cried Ras Thavas. "We will not harm you." Again he attempted to approach the subject, but the man only backed quickly away, growling more fiercely; and then suddenly he wheeled and climbed quickly to the top of the highest shelf, where he squatted upon a corpse and gibbered at us.

"We shall have to have help," said Ras Thavas and, going to the doorway, he blew a signal upon his whistle.

"What are you blowing that for?" demanded the man suddenly. "Who are you? What am I doing here? What has happened to me?"

"Come down," said Ras Thavas. "We are friends."

Slowly the man descended to the floor and came towards us, but he still moved with his knuckles to the pavement He looked about at the corpses and a new light entered his eyes.

"I am hungry!" he cried. "I will eat!" and with that he seized the nearest corpse and dragged it to the floor.

"Stop! Stop!" cried Ras Thavas, leaping forward. "You will ruin the subject," but the man only backed away, dragging the corpse along the floor after him. It was then that the attendants came and with their help we subdued and bound the poor creature. Then Ras Thavas had the attendants bring the body of the ape and he told them to remain, as we might need them.

The subject was a large specimen of the Barsoomian white ape, one of the most savage and fearsome denizens of the Red Planet, and because of the creature's great strength and ferocity Ras Thavas took the precaution to see that it was securely bound before resurgence.

It was a colossal creature about ten or fifteen feet tall, standing erect, and had an intermediary set of arms or legs midway between its upper and lower limbs. The eyes were close together and nonprotruding; the ears were high set, while its snout and teeth were strikingly like those of our African gorilla.

With returning consciousness the creature eyed us questioningly. Several times it seemed to essay to speak but only inarticulate sounds issued from its throat.

Then it lay still for a period.

Ras Thavas spoke to it. "If you understand my words, nod your head." The creature nodded.

"Would you like to be freed of your bonds?" asked the surgeon.

Again the creature nodded an affirmative.

"I fear that you will attempt to injure us, or escape," said Ras Thavas.

The ape was apparently trying very hard to articulate and at last there issued from its lips a sound that could not be misunderstood. It was the single word no.

"You will not harm us or try to escape?" Ras Thavas repeated his question.

"No," said the ape, and this time the word was clearly enunciated.

"We shall see," said Ras Thavas. "But remember that with our weapons we may dispatch you quickly if you attack us."

The ape nodded, and then, very laboriously: "I will not harm you."

At a sign from Ras Thavas the attendants removed the bonds and the creature sat up. It stretched its limbs and slid easily to the floor, where it stood erect upon two feet, which was not surprising, since the white ape goes more often upon two feet than six; a fact of which I was not cognizant at the time, but which Ras Thavas explained to we later in commenting upon the fact that the human subject had gone upon all fours, which, to Ras Thavas, indicated a reversion to type in the fractional ape-brain transplanted to the human skull.

Ras Thavas examined the subject at considerable length and then resumed his examination of the human subject which continued to evince more simian characteristics than human, though it spoke more easily than the ape, because, undoubtedly, of its more perfect vocal organs. It was only by exerting the closest attention that the diction of the ape became understandable at all.

"There is nothing remarkable about these subjects," said Ras Thavas, after devoting half a day to them. "They bear out what I had already determined years ago in the transplanting of entire brains; that the act of transplanting stimulates growth and activity of brain cells. You will note that in each subject the transplanted portions of the brains are more active—they, in a considerable measure, control. That is why we have the human subject displaying distinctly simian characteristics, while the ape behaves in a more human manner; though if longer and closer observation were desirable you would doubtless find that each reverted at times to his own nature—that is the ape would be more wholly an ape and the human more manlike—but it is not worth the time, of which I have already given too much to a rather unprofitable forenoon. I shall leave you now to restore the subjects to anaesthesia while I return to the laboratories above. The attendants will remain here to assist you, if required."

The ape, who had been an interested listener, now stepped forward. "Oh, please, I pray you," it mumbled, "do not again condemn me to these horrid shelves. I recall the day that I was brought here securely bound, and though I have no recollection of what has transpired since I can but guess from the appearance of my own skin and that of these dusty corpses that I have lain here long. I beg that you will permit me to live and either restore me to my fellows or allow me to serve in some capacity in this establishment, of which I saw something between the time of my capture and the day that I was carried into this laboratory, bound and helpless, to one of your cold, ersite slabs."

Ras Thavas made a gesture of impatience. "Nonsense!" he cried. "You are better off here, where you can be preserved in the interests of science."

"Accede to his request," I begged, "and I will myself take over all responsibility for him while I profit by the study that he will afford me."

"Do as you are directed," snapped Ras Thavas as he quit the room.

I shrugged my shoulders. "There is nothing for it, then," I said.

"I might dispatch you all and escape," mused the ape, aloud, "but you would have helped me. I could not kill one who would have befriended me —yet I shrink from the thought of another death. How long have I lain here?"

I referred to the history of his case that had been brought and suspended at the head of the table. "Twelve years," I told him.

"And yet, why not?" he demanded of himself. "This man would slay me— why should I not slay him first."

"It would do you no good," I assured him, "for you could never escape. Instead you would be really killed, dying a death from which Ras Thavas would probably think it not worth while ever to recall you, while I, who might find the opportunity at some later date and who have the inclination, would be dead at your hands and thus incapable of saving you."

I had been speaking in a low voice, close to his ear, that the attendants might not overhear me. The ape listened intently.

"You will do as you suggest?" he asked.

"At the first opportunity that presents itself," I assured him.

"Very well," he said, "I will submit, trusting to you."

A half hour later both subjects had been returned to their shelves.

Chapter 5 THE COMPACT

Days ran into weeks, weeks into months, as day by day I labored at the side of Ras Thavas, and more and more the old surgeon took me into his confidence, more and more he imparted to me the secrets of his skill and his profession.

Gradually he permitted me to perform more and more important functions in the actual practice of his vast laboratory. I started transferring limbs from one subject to another, then internal organs of the digestive tract. Then he entrusted to me a complete operation upon a paying client I removed the kidneys from a rich old man, replacing them with healthy ones from a young subject The following day I gave a stunted child new thyroid glands. A week later I transferred two hearts and then, at last, came the great day for me—unassisted, with Ras Thavas standing silently beside me, I took the brain of an old man and transplanted it within the cranium of a youth.

When I had done Ras Thavas laid a hand upon my shoulder. "I could not have done better myself," he said. He seemed much elated and I could not but wonder at this unusual demonstration of emotion upon his part, he who so prided himself upon his lack of emotionalism. I had often pondered the purpose which influenced Ras Thavas to devote so much time to my training, but never had I hit upon any more satisfactory explanation than that he had need of assistance in his growing practice. Yet when I consulted the records, that were now open to me, I discovered that his practice was no greater than it had been for many years; and even had it been there was really no reason why he should have trained me in preference to one of his red-Martian assistants, his belief in my loyalty not being sufficient warrant, in my mind, for this preferment when he could, as well as not have kept me for a bodyguard and trained one of his own kind to aid him in his surgical work.

But I was presently to learn that he had an excellent reason for what he was doing—Ras Thavas always had an excellent reason for whatever he did. One night after we had finished our evening meal he sat looking at me intently as he so often did, as though he would read my mind, which, by the way, he was totally unable to do, much to his surprise and chagrin; for unless a Martian is constantly upon the alert any other Martian can read clearly his every thought; but Ras Thavas was unable to read mine. He said that it was due to the fact that I was not a Barsoomian. Yet I could often read the minds of his assistants, when they were off their guard, though never had I read aught of Ras Thavas' thoughts, nor, I am sure, had any other read them. He kept his brain sealed like one of his own blood jars, nor was he ever for a moment found with his barriers down.

He sat looking at me this evening for a long time, nor did it in the least embarrass me, so accustomed was I to his peculiarities. "Perhaps," he said presently, "one of the reasons that I trust you is due to the fact that I cannot ever, at any time, fathom your mind; so, if you harbor traitorous thoughts concerning me I do not know it, while the others, every one of them, reveal their inmost souls to my searching mind and in each one there is envy, jealousy or hatred of me. Them, I know, I cannot trust. Therefore I must accept the risk and place all my dependence upon you, and my reason tells me that my choice is a wise one—I have told you upon what grounds it based my selection of you as my bodyguard. The same holds true in my selection of you for the thing I have in mind. You cannot harm me without harming yourself and no man will intentionally do that; nor is there any reason why you should feel any deep antagonism towards me.

"You are, of course, a sentimentalist and doubtless you look with horror upon many of the acts of a sane, rational, scientific mind; but you are also highly intelligent and can, therefore, appreciate better than another, even though you may not approve them, the motives that prompt me to do many of those things of which your sentimentality disapproves. I may have offended you, but I have never wronged you, nor have I wronged any creature for which you might have felt some of your so-called friendship or love. Are my premises incorrect, or my reasoning faulty?"

I assured him to the contrary.

"Very well! Now let me explain why I have gone to such pains to train you as no other human being, aside from myself, has ever been trained. I am not ready to use you yet, or rather you are not ready; but if you know my purpose you will realize the necessity for bending your energy to the consummation of my purpose, and to that end you will strive even more diligently than you have to perfect yourself in the high, scientific art I am imparting to you.

"I am a very old man," he continued after a brief pause, "even as age goes upon Barsoom. I have lived more than a thousand years. I have passed the allotted natural span of life, but I am not through with my life's work—I have but barely started it. I must not die. Barsoom must not be robbed of this wondrous brain and skill of mine. I have long had in mind a plan to thwart death, but it required another with skill equal to mine—two such might live for ever. I have selected you to be that other, for reasons that I already have explained—they are undefiled by sentimentalism. I did not choose you because I love you, or because I feel friendship for you, or because I think that you love me, or feel friendship towards me. I chose you because I knew that of all the inhabitants of a world you were the one least likely to fail me. For a time you will have my life in your hands. You will understand now why I have not been able to choose carelessly.

"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."

"And what became of the princess?" I asked.

"Perhaps she died—her party was separated in Phundahl—but death could not more definitely prevent her return to Duhor. The Princess of Duhor will never again see her native country."

"But you may!" I cried, for I had suddenly hit upon a plan. "Where is Duhor?"

"You are going there?" she asked, laughingly.

"Yes!" "You are mad, my friend," she said. "Duhor lies a full seven thousand, eight hundred haads from Toonol, upon the opposite side of the snow-clad Artolian Hills. You, a stranger and alone, could never reach it; for between lie the Toonolian Marshes, wild hordes, savage beasts and warlike cities. You would but die uselessly within the first dozen haads, even could you escape from the island upon which stands the laboratory of Ras Thavas; and what motive is there to prompt you to such a useless sacrifice?"

I could not tell her. I could not look upon that withered figure and into that hideous and disfigured face and say: "it is because I love you, Valla Dia." But that, alas, was my only reason. Gradually, as I had come to know her through the slow revealment of the wondrous beauty of her mind and soul, there had crept into my heart a knowledge of my love; and yet, explain it I cannot, I could not speak the words to that frightful old hag. I had seen the gorgeous mundane tabernacle that had housed the equally gorgeous spirit of the real Valla Dia—that I could love; her heart and soul and mind I could love; but I could not love the body of Xaxa. I was torn, too, by other emotions, induced by a great doubt—could Valla Dia return my love. Habilitated in the corpse of Xaxa, with no other suitor, nay, with no other friend she might, out of gratitude or through sheer loneliness, be attracted to me; but once again were she Valla Dia the beautiful and returned to the palace of her king, surrounded by the great nobles of Duhor, would she have either eyes or heart for a lone and friendless exile from another world? I doubted it—and yet that doubt did not deter me from my determination to carry out, as far as Fate would permit, the mad scheme that was revolving in my brain.

"You have not answered my question, Vad Varo," she interrupted my surging thoughts. "Why would you do this thing?"

"To right the wrong that has been done you, Valla Dia," I said.

She sighed. "Do not attempt it, please," she begged. "You would but rob me of my one friend, whose association is the only source of happiness remaining to me. I appreciate your generosity and your loyalty, even though I may not understand them; your unselfish desire to serve me at such suicidal risk touches me more deeply than I can reveal, adding still further to the debt I owe you; but you must not attempt it—you must not."

"If it troubles you, Valla Dia," I replied, "we will not speak of it again; but know always that it is never from my thoughts. Some day I shall find a way, even though the plan I now have fails me."

The days moved on and on, the gorgeous Martian nights, filled with her hurtling moons, followed one upon another. Ras Thavas spent more and more time in directing my work of brain transference. I had long since become an adept; and I realized that the time was rapidly approaching when Ras Thavas would feel that he could safely entrust to my hands and skill his life and future. He would be wholly within my power and he knew that I knew it. I could slay him; I could permit him to remain for ever in the preserving grip of his own anaesthetic; or I could play any trick upon him that I chose, even to giving him the body of a calot or a part of the brain of an ape; but he must take the chance and that I knew, for he was failing rapidly. Already almost stone blind, it was only the wonderful spectacles that he had himself invented that permitted him to see at all; long deaf, he used artificial means for hearing; and now his heart was showing symptoms of fatigue that he could not longer ignore.

One morning I was summoned to his sleeping apartment by a slave. I found the old surgeon lying, a shrunken, pitiful heap of withered skin and bones.

"We must hasten, Vad Varo," he said in a weak whisper. "My heart was like to have stopped a few tals ago. It was then that I sent for you." He pointed to a door leading from his chamber. "There," he said, "you will find the body I have chosen. There, in the private laboratory I long ago built for this very purpose, you will perform the greatest surgical operation that the universe has ever known, transferring its most perfect brain to the most beautiful and perfect body that ever has passed beneath these ancient eyes. You will find the head already prepared to receive my brain; the brain of the subject having been removed and destroyed—totally destroyed by fire. I could not possibly chance the existence of a brain desiring and scheming to regain its wondrous body. No, I destroyed it. Call slaves and have them bear my body to the ersite slab."

"That will not be necessary," I told him; and lifting his shrunken form in my arms as he had been an earthly babe, I carried him into the adjoining room where I found a perfectly lighted and appointed laboratory containing two operating tables, one of which was occupied by the body of a red-man. Upon the surface of the other, which was vacant, I laid Ras Thavas, then I turned to look at the new envelope he had chosen. Never, I believe, had I beheld so perfect a form, so handsome a face—Ras Thavas had indeed chosen well for himself. Then I turned back to the old surgeon. Deftly, as he had taught me, I made the two incisions and attached the tubes. My finger rested upon the button that would start the motor pumping his blood from his veins and his marvellous preservative-anaesthetic into them. Then I spoke.

"Ras Thavas," I said, "You have long been training me to this end. I have labored assiduously to prepare myself that there might be no slightest cause for apprehension as to the outcome. You have, coincidentally, taught me that one's every act should be prompted by self-interest only. You are satisfied, therefore, that I am not doing this for you because I love you, or because I feel any friendship for you; but you think that you have offered me enough in placing before me a similar opportunity for immortality.

"Regardless of your teaching I am afraid that I am still somewhat of a sentimentalist I crave the redressing of wrongs. I crave friendship and love. The price you offer is not enough. Are you willing to pay more that this operation may be successfully concluded?"

He looked at me steadily for a long minute. "What do you want?" he asked. I could see that he was trembling with anger, but he did not raise his voice.

"Do you recall 4296-E-2631-H?" I inquired.

"The subject with the body of Xaxa? Yes, I recall the case. What of it?"

"I wish her body returned to her. That is the price you must pay for this operation."

He glared at me. "It is impossible. Xaxa has the body. Even if I cared to do so, I could never recover it. Proceed with the operation!" "When you have promised me," I insisted.

"I cannot promise the impossible—I cannot obtain Xaxa. Ask me something else. I am not unwilling to grant any reasonable request."

"That is all I wish—just that; but I do not insist that you obtain the body. If I bring Xaxa here will you make the transfer?"

"It would mean war between Toonol and Phundahl," he fumed.

"That does not interest me," I said. "Quick! Reach a decision. In five tals I shall press this button. If you promise what I ask, you shall be restored with a new and beautiful body; if you refuse you shall lie here in the semblance of death for ever."

"I promise," he said slowly, "that when you bring the body of Xaxa to me I will transfer to that body any brain that you select from among my subjects."

"Good!" I exclaimed, and pressed the button.

Chapter 6 DANGER

Ras Thavas awakened from the anaesthetic a new and gorgeous creature— a youth of such wondrous beauty that he seemed of heavenly rather than worldly origin; but in that beautiful head was the hard, cold, thousand-year-old brain of the master surgeon. As he opened his eyes he looked upon me coldly.

"You have done well," he said.

"What I have done, I have done for friendship—perhaps for love," I said, "so you can thank the sentimentalism you decry for the success of the transfer."

He made no reply.

"And now," I continued, "I shall look to you for the fulfilment of the promise you have made me."

"When you bring Xaxa's body I shall transfer to it the brain of any of my subjects you may select," he said, "but were I you, I would not risk my life in such an impossible venture—you cannot succeed. Select another body—there are many beautiful ones—and I will give it the brain of 4296-E-2631-H.

"None other than the body now owned by the Jeddara Xaxa will fulfill your promise to me," I said.

He shrugged and there was a cold smile upon his handsome lips. "Very well," he said, "fetch Xaxa. When do you start?"

"I am not yet ready. I will let you know when I am."

"Good and now begone—but wait! First go to the office and see what cases await us and if there be any that do not require my personal attention, and they fall within your skill and knowledge, attend to them yourself."

As I left him I noticed a crafty smile of satisfaction upon his lips. What had aroused that? I did not like it and as I walked away I tried to conjure what could possibly have passed through that wondrous brain to call forth at that particular instant so unpleasant a smile. As I passed through the doorway and into the corridor beyond I heard him summon his personal slave and body servant, Yamdor, a huge fellow whose loyalty he kept through the bestowal of lavish gifts and countless favors. So great was the fellow's power that all feared him, as a word to the master from the lips of Yamdor might easily send any of the numerous slaves or attendants to an ersite slab for eternity. It was rumored that he was the result of an unnatural experiment which had combined the brain of a woman with the body of a man, and there was much in his actions and mannerisms to justify this general belief. His touch, when he worked about his master, was soft and light, his movements graceful, his ways gentle, but his mind was jealous, vindictive and unforgiving.

I believe that he did not like me, through jealousy of the authority I had attained in the establishment of Ras Thavas; for there was no questioning the fact that I was a lieutenant, while he was but a slave; yet he always accorded me the utmost respect. He was, however, merely a minor cog in the machinery of the great institution presided over by the sovereign mind of Ras Thavas, and as such I had given him little consideration; nor did I now as I bent my steps towards the office.

I had gone but a short distance when I recalled a matter of importance upon which it was necessary for me to obtain instructions from Ras Thavas immediately; and so I wheeled about and retraced my way towards his apartments, through the open doorway of which, as I approached, I heard the new voice of the master surgeon. Ras Thavas had always spoken in rather loud tones, whether as a vocal reflection of his naturally domineering and authoritative character, or because of his deafness, I do not know; and now, with the fresh young vocal cords of his new body, his words rang out clearly and distinctly in the corridor leading to his room.

"You will, therefore, Yamdor," he was saying, "go at once and, selecting two slaves in whose silence and discretion you may trust, take the subject from the apartments of Vad Varo and destroy it—let no vestige of body or brain remain. Immediately after, you will bring the two slaves to the laboratory F-30-L, permitting them to speak to no one, and I will consign them to silence and forgetfulness for eternity. Vad Varo will discover the absence of the subject and report the matter to me."

"During my investigation you will confess that you aided 4296-E-2631-H to escape, but that you have no idea where it intended going. I will sentence you to death as punishment, but at last explaining how urgently I need your services and upon your solemn promise never to transgress again, I will defer punishment for the term of your continued good behaviour. Do you thoroughly understand the entire plan?"

"Yes, master," replied Yamdor.

"Then depart at once and select the slaves who are to assist you."

Quickly and silently I sped along the corridor until the first intersection permitted me to place myself out of sight of anyone coming from Ras Thavas' apartment; then I went directly to the chamber occupied by Valla Dia. Unlocking the door I threw it open and beckoned her to come out. "Quick! Valla Dia!" I cried. "No time is to be lost. In attempting to save you I have but brought destruction upon you. First we must find a hiding place for you, and that at once— afterwards we can plan for the future."

The place that first occurred to me as affording adequate concealment was the half forgotten vaults in the pits beneath the laboratories, and towards these I hastened Valla Dia. As we proceeded I narrated all that had transpired, nor did she once reproach me; but, instead, expressed naught but gratitude for what she was pleased to designate as my unselfish friendship. That it had miscarried, she assured me, was no reflection upon me and she insisted that she would rather die in the knowledge that she possessed one such friend than to live on indefinitely, friendless.

We came at last to the chamber I sought—vault L-42-X, in building 4-J-21, where reposed the bodies of the ape and the man, each of which possessed half the brain of the other. Here I was forced to leave Valla Dia for the time, that I might hasten to the office and perform the duties imposed upon me by Ras Thavas, lest his suspicions be aroused when Yamdor reported that he had found her apartment vacant.

I reached the office without it being discovered by anyone who might report the fact to Ras Thavas that I had been a long time coming from his apartment. To my relief, I found there were no cases. Without appearing in any undue haste, I nevertheless soon found an excuse to depart and at once made my way towards my own quarters, moving in a leisurely and unconcerned manner and humming, as was my wont (a habit which greatly irritated Ras Thavas), snatches from some song that had been popular at the time that I quit Earth. In this instance it was "Oh, Frenchy."

I was thus engaged when I met Yamdor moving hurriedly along the corridor leading from my apartment, in company with two male slaves. I greeted him pleasantly, as was my custom, and he returned my greeting; but there was an expression of fear and suspicion in his eyes. I went at once to my quarters, opened the door leading to the chamber formerly occupied by Valla Dia and then hastened immediately to the apartment of Ras Thavas, where I found him conversing with Yamdor. I rushed in apparently breathless and simulating great excitement.

"Ras Thavas," I demanded, "what have you done with 4296-E-2631-H? She has disappeared; her apartment is empty; and as I was approaching it I met Yamdor and two other slaves coming from that direction." I turned then upon Yamdor and pointed an accusing finger at him. "Yamdor!" I cried. "What have you done with this woman?"

Both Ras Thavas and Yamdor seemed genuinely puzzled and I congratulated myself that I had thus readily thrown them off the track. The master surgeon declared that he would make an immediate investigation; and he at once ordered a thorough search of the ground and of the island outside the enclosure. Yamdor denied any knowledge of the woman and I, at least, was aware of the sincerity of his protestations, but not so Ras Thavas. I could see a hint of suspicion in his eyes as he questioned his body servant; but evidently he could conjure no motive for any such treasonable action on the part of Yamdor as would have been represented by the abduction of the woman and the consequent gross disobedience of orders.

Ras Thavas' investigation revealed nothing. I think as it progressed that he became gradually more and more imbued with a growing suspicion that I might know more about the disappearance of Valla Dia than my attitude indicated, for I presently became aware of a delicately concealed espionage. Up to this time I had been able to smuggle food to Valla Dia every night, after Ras Thavas had retired to his quarters. Then, on one occasion, I suddenly became subconsciously aware that I was being followed, and instead of going to the vaults I went to the office, where I added some observations to my report upon a case I had handled that day. Returning to my room I hummed a few bars from "Over There," that the suggestion of my unconcern might be accentuated. From the moment that I quit my quarters until I returned to them I was sure that eyes had been watching my every move. What was I to do? Valla Dia must have food, without it she would die; and were I to be followed to her hiding place while taking it to her, she would die; Ras Thavas would see to that.

Half the night I lay awake, racking my brains for some solution to the problem.

There seemed only one way—I must elude the spies. If I could do this but one single time I could carry out the balance of a plan that had occurred to me, and which was, I thought, the only one feasible that might eventually lead to the resurrection of Valla Dia in her own body. The way was long, the risks great; but I was young, in love and utterly reckless of consequences in so far as they concerned me; it was Valla Dia's happiness alone that I could not risk too greatly, other than under dire stress. Well, the stress existed and I must risk that even as I risked my life.

My plan was formulated and I lay awake upon my sleeping silks and furs in the darkness of my room, awaiting the time when I might put it into execution. My window, which was upon the third floor, overlooked the walled enclosure, upon the scarlet sward of which I had made my first bow to Barsoom. Across the open casement I had watched Cluros, the farther moon, take his slow deliberate way.

He had already set. Behind him, Thuria, his elusive mistress, fled through the heavens. In five xats (about 15 minutes) she would set; and then for about three and three quarters Earth hours the heavens would be dark, except for the stars.

In the corridor, perhaps, lurked those watchful eyes. I prayed God that they might not be elsewhere as Thuria sank at last beneath the horizon and I swung to my window ledge, in my hand a long rope fabricated from braided strips tom from my sleeping silks while I had awaited the setting of the moons. One end I had fastened to a heavy sorapus bench which I had drawn close to the window. I dropped the free end of the rope and started my descent. My Earthly muscles, untried in such endeavours, I had not trusted to the task of carrying me to my window ledge in a single leap, when I should be returning. I felt that they would, but I did not know; and too much depended upon the success of my venture to risk any unnecessary chance of failure. And so I had prepared the rope.

Whether I was being observed I did not know. I must go on as though none were spying upon me. In less then four hours Thuria would return (just before the sudden Barsoomian dawn) and in the interval I must reach Valla Dia, persuade her of the necessity of my plan and carry out its details, returning to my chamber before Thuria could disclose me to any accidental observer. I carried my weapons with me and in my heart was unbending determination to slay whoever might cross my path and recognize me during the course of my errand, however innocent of evil intent against me he might be.

The night was quiet except for the usual distant sounds that I had heard ever since I had been here—sounds that I had interpreted as the cries of savage beasts. Once I had asked Ras Thavas about them, but he had been in ill humor and had ignored my question. I reached the ground quickly and without hesitation moved directly to the nearest entrance of the building, having previously searched out and determined upon the route I would follow to the vault. No one was visible and I was confident, when at last I reached the doorway, that I had come through undetected. Valla Dia was so happy to see me again that it almost brought the tears to my eyes.

"I thought that something had happened to you," she cried, "for I knew that you would not remain away so long of your own volition."

I told her of my conviction that I was being watched and that it would not be possible for me longer to bring food to her without incurring almost certain detection, which would spell immediate death for her.

"There is a single alternative," I said, "and that I dread even to suggest and would not were there any other way. You must be securely hidden for a long time, until Ras Thavas' suspicions have been allayed; for as long as he has me watched I cannot possibly carry out the plans I have formulated for your eventual release, the restoration of your own body and your return to Duhor."

"Your will shall be my law, Vad Varo."

I shook my head. "It will be harder for you than you imagine."

"What is the way?" she asked.

I pointed, to the ersite topped table. "You must pass again though that ordeal that I may hide you away in this vault until the time is ripe for the carrying out of my plans. Can you endure it?"

She smiled. "Why not?" she asked. "It is only sleep—if it lasts for ever I shall be no wiser."

I was surprised that she did not shrink from the idea, but I was very glad since I knew that it was the only way that we had a chance for success. Without my help she disposed herself upon the ersite slab.

"I am ready, Vad Varo," she said, bravely; "but first promise me that you will take no risks in this mad venture. You cannot succeed. When I close my eyes I know that it will be for the last time if my resurrection depends upon the successful outcome of the maddest venture that ever man conceived; yet I am happy, because I know that it is inspired by the greatest friendship with which any mortal woman has ever been blessed."

As she talked I had been adjusting the tubes and now I stood beside her with my finger upon the starting button of the motor.

"Good-bye, Vad Varo," she whispered.

"Not good-bye, Valla Dia, but only a sweet sleep for what to you will be the briefest instant. You will seem but to close your eyes and open them again. As you see me now, I shall be standing here beside you as though I never had departed from you. As I am the last that you look upon to-night before you close your eyes, so shall I be the first that you shall look upon as you open them on that new and beautiful morning; but you shall not again look forth through the eyes of Xaxa, but from the limpid depths of your own beautiful orbs."

She smiled and shook her head. Two tears formed beneath her lids. I pressed her hand in mine and touched the button.

Chapter 7 SUSPICIONS

In so far as I could know I reached my apartment without detection. Hiding my rope where I was sure it would not be discovered, I sought my sleeping silks and furs and was soon asleep.

The following morning as I emerged from my quarters I caught a fleeting glimpse of a figure in a nearby corridor and from then on for a long time I had further evidence that Ras Thavas suspicioned me. I went at once to his quarters, as had been my habit. He seemed restless, but he gave me no hint that he held any assurance that I had been responsible for the disappearance of Valla Dia, and I think that he was far from positive of it. It was simply that his judgment pointed to the fact that I was the only person who might have any reason for interfering in any way with this particular subject, and he was having me watched to either prove or disprove the truth of his reasonable suspicions. His restlessness he explained to me himself.

"I have often studied the reaction of others who have undergone brain transference," he said, "and so I am not wholly surprised at my own. Not only has my brain energy been stimulated, resulting in an increased production of nervous energy, but I also feel the effects of the young tissue and youthful blood of my new body. They are affecting my consciousness in a way that my experiment had vaguely indicated, but which I now see must be actually experienced to be fully understood. My thoughts, my inclinations, even my ambitions have been changed, or at least coloured, by the transfer. It will take some time for me to find myself."

Though uninterested, I listened politely until he was through and then I changed the subject "Have you located the missing woman?" I asked.

He shook his head, negatively.

"You must appreciate, Ras Thavas," I said, "that I fully realize that you must have known that the removal or destruction of that woman would entirely frustrate my entire plan. You are master here. Nothing that passes is without your knowledge."

"You mean that I am responsible for the disappearance of the woman?" he demanded.

"Certainly. It is obvious. I demand that she be restored."

He lost his temper. "Who are you to demand?" he shouted. "You are naught but a slave. Cease your impudence or I shall erase you—erase you. It will be as though you never had existed."

I laughed in his face. "Anger is the most futile attribute of the sentimentalist," I reminded him. "You will not erase me, for I alone stand between you and mortality."

"I can train another," he parried.

"But you could not trust him," I pointed out.

"But you bargained with me for my life when you had me in your power," he cried.

"For nothing that it would have harmed you to have granted willingly. I did not ask anything for myself. Be that as it may, you will trust me again. You will trust, for no other reason than that you will be forced to trust me. So why not win my gratitude and my loyalty by returning the woman to me and carrying out in spirit as well as in fact the terms of our agreement?"

He turned and looked steadily at me. "Vad Varo," he said, "I give you the word of honor of a Barsoomian noble that I know absolutely nothing concerning the whereabouts of 4296-E-2631-H."

"Perhaps Yamdor does," I persisted.

"Nor Yamdor. Of my knowledge no person in any way connected with me knows what became of it. I have spoken the truth."

Well, the conversation was not as profitless as it might appear, for I was sure that it had almost convinced Ras Thavas that I was equally as ignorant of the fate of Valla Dia as was he. That it had not wholly convinced him was evidenced by the fact that the espionage continued for a long time, a fact which determined me to use Ras Thavas' own methods in my own defence. I had had allotted to me a number of slaves, and these I had won over by kindness and understanding until I knew that I had the full measure of their loyalty. They had no reason to love Ras Thavas and every reason to hate him; on the other hand they had no reason to hate me, and I saw to it that they had every reason to love me.

The result was that I had no difficulty in enlisting the services of a couple of them to spy upon Ras Thavas' spies, with the result that I was soon apprised that my suspicions were well founded—I was being constantly watched every minute that I was out of my apartments, but the spying did not come beyond my outer chamber walls. That was why I had been successful in reaching the vault in the manner that I had, the spies having assumed that I would leave my chamber only by its natural exit, had been content to guard that and permit my windows to go unwatched.

I think it was about two of our months that the spying continued and then my men reported that it seemed to have ceased entirely. All that time I was fretting at the delay, for I wanted to be about my plans which would have been absolutely impossible for me to carry out if I were being watched. I had spent the interval in studying the geography of the north-eastern Barsoomian hemisphere where my activities were to be carried on, and also in scanning a great number of case histories and inspecting the subjects to which they referred; but at last, with the removal of the spies, it began to look as though I might soon commence to put my plans in active operation.

Ras Thavas had for some time permitted me considerable freedom in independent investigation and experiment, and this I determined to take advantage of in every possible way that might forward my plans for the resurrection of Valla Dia. My study of the histories of many of the cases had been with the possibility in mind of discovering subjects that might be of assistance to me in my venture. Among those that had occupied my careful attention were, quite naturally, the cases with which I had been most familiar, namely: 378-J-493811-P, the red-man from whose vicious attack I had saved Ras Thavas upon the day of my advent upon Mars; and he whose brain had been divided with an ape.

The former, 378-J-493811-P, had been a native of Phundahl—a young warrior attached to the court of Xaxa, Jeddara of Phundahl—and a victim of assassination. His body had been purchased by a Phundahlian noble for the purpose, as Ras Thavas had narrated, of winning the favor of a young beauty. I felt that I might possibly enlist his services, but that would depend upon the extent of his loyalty towards Xaxa, which I could only determine by reviving and questioning him.

He whose brain had been divided with an ape had originated in Ptarth, which lay at a considerable distance to the west of Phundahl and a little south and about an equal distance from Duhor, which lay north and a little west of it. An inhabitant of Ptarth, I reasoned, would know much of the entire country included in the triangle formed by Phundahl, Ptarth and Duhor; the strength and ferocity of the great ape would prove of value in crossing beast infested wastes; and I felt that I could hold forth sufficient promise to the human half of the great beast's brain, which really now dominated the creature, to win its support and loyalty. The third subject that I had tentatively selected had been a notorious Toonolian assassin, whose audacity, fearlessness and swordsmanship had won for him a reputation that had spread far beyond the boundaries of his country.

Ras Thavas, himself a Toonolian, had given me something of the history of this man whose grim calling is not without honor upon Barsoom, and which Gor Hajus had raised still higher in the esteem of his countrymen through the fact that he never struck down a woman or a good man and that he never struck from behind.

His killings were always the results of fair fights in which the victim had every opportunity to defend himself and slay his attacker; and he was famous for his loyalty to his friends. In fact this very loyalty had been a contributing factor in his downfall which had brought him to one of Ras Thavas' ersite slabs some years since, for he had earned the enmity of Vobis Kan, Jeddak of Toonol, through his refusal to assassinate a man who once had befriended Gor Hajus in some slight degree; following which Vobis Kan conceived the suspicion that Gor Hajus had him marked for slaying. The result was inevitable: Gor Hajus was arrested and condemned to death; immediately following the execution of the sentence an agent of Ras Thavas had purchased the body.

These three, then, I had chosen to be my partners in my great adventure. It is true that I had not discussed the matter with any one of them, but my judgment assured me that I would have no difficulty in enlisting their services and loyalty in return for their total resurrection.

My first task lay in renewing the organs of 378-J-493811-P and of Gor Hajus which had been injured by the wounds that had laid them low; the former requiring a new lung and the latter a new heart, his executioner having run him through with a short-sword. I hesitated to ask Ras Thavas' permission to experiment on these subjects for fear of the possibility of arousing his suspicions, in which event he would probably have them destroyed, and so I was forced to accomplish my designs by subterfuge and stealth. To this end I made it a practice for weeks to carry my regular laboratory work far into the night, often requiring the services of various assistants that all might become accustomed to the sight of me at work at unusual hours. In my selection of these assistants I made it a point to choose two of the very spies that Ras Thavas had set to watching me. While it was true that they were no longer employed in this particular service, I had hopes that they would carry word of my activities to their master; and I was careful to see that they received from me the proper suggestions that would mould their report in language far from harmful to me. By the merest suggestion I carried to them the idea that I worked thus late purely for the love of the work itself and the tremendous interest in it that Ras Thavas had awakened within my mind. Some nights I worked with assistants and as often I did not, but always I was careful to assure myself that the following morning those in the office were made aware that I had labored far into the preceding night.

This groundwork carefully prepared, I had comparatively little fear of the results of actual discovery when I set to work upon the warrior of Phundahl and the assassin of Toonol. I chose the former first. His lung was badly injured where my blade had passed through it, but from the laboratory where were kept fractional bodies I brought a perfect lung, with which I replaced the one that I had ruined. The work occupied but half the night. So anxious was I to complete my task that I immediately opened up the breast of Gor Hajus, for whom I had selected an unusually strong and powerful heart and by working rapidly I succeeded in completing the transference before dawn. Having known the nature of the wounds that had dispatched these two men, I had spent weeks in performing similar operations that I might perfect myself especially in this work; and having encountered no unusual pathological conditions in either subject, the work had progressed smoothly and with great rapidity. I had completed what I had feared would be the most difficult part of my task and now, having removed as far as possible all signs of the operation except the therapeutic tape which closed the incisions, I returned to my quarters for a few minutes of much needed rest, praying that Ras Thavas would not by any chance examine either of the subjects upon which I had been working, although I had fortified myself against such a contingency by entering full details of the operation upon the history card of each subject that, in the event of discovery, any suspicion of ulterior motives upon my part might be allayed by my play of open frankness.

I arose at the usual time and went at once to Ras Thavas' apartment, where I was met with a bombshell that nearly wrecked my composure. He eyed me closely for a long minute before he spoke.

"You worked late last night, Vad Varo," he said.

"I often do," I replied, lightly; but my heart was heavy as a stone.

"And what might it have been that so occupied your interest?" he inquired.

I felt as a mouse with which the cat is playing. "I have been doing quite a little lung and heart transference of late," I replied, "and I became so engrossed with my work that I did not note the passage of time."

"I have known that you worked late at night. Do you think it wise?"

At that moment I felt that it had been very unwise, yet I assured him to the contrary.

"I was restless," he said. "I could not sleep and so I went to your quarters after midnight, but you were not there. I wanted someone with whom to talk, but your slaves knew only that you were not there—where you were they did not know—so I set out to search for you." My heart went into my sandals. "I guessed that you were in one of the laboratories, but though I visited several I did not find you." My heart arose with the lightness of a feather. "Since my own transference I have been cursed with restlessness and sleeplessness, so that I could almost wish for the return of my old corpse—the youth of my body harmonizes not with the antiquity of my brain. It is filled with latent urges and desires that comport illy with the serious subject matter of my mind."

"What your body needs," I said, "is exercise. It is young, strong, virile. Work it hard and it will let your brain rest at night."

"I know that you are right," he replied. "I have reached that same conclusion myself. In fact, not finding you, I walked in the gardens for an hour or more before returning to my quarters, and then I slept soundly. I shall walk every night when I cannot sleep, or I shall go into the laboratories and work as do you."

This news was most disquieting. Now I could never be sure but that Ras Thavas was wandering about at night and I had one more very important night's work to do, perhaps two. The only way that I could be sure of him was to be with him.

"Send for me when you are restless," I said, "and I will walk and work with you. You should not go about thus at night alone."

"Very well," he said, "I may do that occasionally."

I hoped that he would do it always, for then I would know that when he failed to send for me he was safe in his own quarters. Yet I saw that I must henceforth face the menace of detection; and knowing this I determined to hasten the completion of my plans and to risk everything on a single bold stroke.

That night I had no opportunity to put it into action as Ras Thavas sent for me early and informed me that we would walk in the gardens until he was tired. Now, as I needed a full night for what I had in mind and as Ras Thavas walked until midnight, I was compelled to forego everything for that evening, but the following morning I persuaded him to walk early on the pretext that I should like to go beyond the enclosure and see something of Barsoom beside the inside of his laboratories and his gardens. I had little confidence that he would grant my request, yet he did so. I am sure he never would have done it had he possessed his old body; but thus greatly had young blood changed Ras Thavas.

I had never been beyond the buildings, nor had I seen beyond, since there were no windows in the outside walls of any of the structures and upon the garden side the trees had grown to such a height that they obstructed all view beyond them. For a time we walked in another garden just inside the outer wall, and then I asked Ras Thavas if I might go even beyond this.

"No," he said. "It would not be safe."

"And why not?" I asked.

"I will show you and at the same time give you a much broader view of the outside world than you could obtain by merely passing through the gate. Come, follow me!" He led me immediately to a lofty tower that rose at the comer of the largest building of the group that comprised his vast establishment. Within was a circular runway which led not only upward, but down as well. This we ascended, passing openings at each floor, until we came at last out upon its lofty summit.

About me spread the first Barsoomian landscape of any extent upon which my eyes had yet rested during the long months that I had spent upon the Red Planet. For almost an Earthly year I had been immured within the grim walls of Ras Thavas' bloody laboratory, until, such creatures of habit are we, the weird life there had grown to seem quite natural and ordinary; but with this first glimpse of open country there surged up within me an urge for freedom, for space, for room to move about, such as I knew would not be long denied.

Directly beneath lay an irregular patch of rocky land elevated perhaps a dozen feet or more above the general level of the immediately surrounding country. Its extent was, at a rough guess, a hundred acres. Upon this stood the buildings and grounds, which were enclosed in a high wall. The tower upon which we stood was situated at about the centre of the total area enclosed. Beyond the outer wall was a strip of rocky ground on which grew a sparse forest of fair sized trees interspersed with patches of a jungle growth, and beyond all, what appeared to be an oozy marsh through which were narrow water courses connecting occasional open water—little lakes, the largest of which could have comprised scarce two acres. This landscape extended as far as the eye could reach, broken by occasional islands similar to that upon which we were and at a short distance by the skyline of a large city, whose towers and domes and minarets glistened and sparkled in the sun as though plated with shining metals and picked out with precious gems.

This, I knew, must be Toonol and all about us the Great Toonolian Marshes which extend nearly eighteen hundred Earth miles east and west and in some places have a width of three hundred miles. Little is known about them in other portions of Barsoom as they are frequented by fierce beasts, afford no landing places for fliers and are commanded by Phundahl at their western end and Toonol at the east, inhospitable kingdoms that invite no intercourse with the outside world and maintain their independence alone by their inaccessibility and savage aloofness.

As my eyes returned to the island at our feet I saw a huge form emerge from one of the nearby patches of jungle a short distance beyond the outer wall. It was followed by a second and a third. Ras Thavas saw that the creatures had attracted my notice.

"There," he said, pointing to them, "are three of a number of similar reasons why it would not have been safe for us to venture outside the enclosure."

They were great white apes of Barsoom, creatures so savage that even that fierce Barsoomian lion, the banth, hesitates to cross their path.

"They serve two purposes," explained Ras Thavas. "They discourage those who might otherwise creep upon me by night from the city of Toonol, where I am not without many good enemies, and they prevent desertion upon the part of my slaves and assistants."

"But how do your clients reach you?" I asked. "How are your supplies brought in?"

He tuned and pointed down toward the highest portion of the irregular roof of the building below us. Built upon it was a large, shed-like structure. "There," he said, "I keep three small ships. One of them goes every day to Toonol."

I was overcome with eagerness to know more about these ships, in which I thought I saw a much needed means of escape from the island; but I dared not question him for fear of arousing his suspicions.

As we turned to descend the tower runway I expressed interest in the structure which gave evidence of being far older than any of the surrounding buildings.

"This tower," said Ras Thavas, "was built some twenty-three thousand years ago by an ancestor of mine who was driven from Toonol by the reigning Jeddak of the time. Here, and upon other islands, he gathered a considerable following, dominated the surrounding marshes and defended himself successfully for hundreds of years. While my family has been permitted to return to Toonol since, this has been their home; to which, one by one, have been added the various buildings which you see about the tower, each floor of which connects with the adjacent building from the roof to the lowest pits beneath the ground."

This information also interested me greatly since I thought that I saw where it too might have considerable bearing upon my plan of escape, and so, as we descended the runway, I encouraged Ras Thavas to discourse upon the construction of the tower, its relation to the other buildings and especially its accessibility from the pits. We walked again in the outer garden and by the time we returned to Ras Thavas' quarters it was almost dark and the master surgeon was considerably fatigued.

"I feel that I shall sleep well to-night," he said as I left him.

"I hope so, Ras Thavas," I replied.

Chapter 8 ESCAPE

It was usually about three hours after the evening meal, which was served immediately after dark, that the establishment quieted down definitely for the night. While I should have preferred waiting longer before undertaking that which I had in mind, I could not safely do so, since there was much to be accomplished before dawn. So it was that with the first indications that the occupants of the building in which my work was to be performed had retired for the night, I left my quarters and went directly to the laboratory, where, fortunately for my plans, the bodies of Gor Hajus, the assassin of Toonol, and 378-J-493811-P both reposed. It was the work of a few minutes to carry them to adjoining tables, where I quickly strapped them securely against the possibility that one or both of them might not be willing to agree to the proposition I was about to make them, and thus force me to anaesthetize them again. At last the incisions were made, the tubes attached and the motors started. 378-J-493811-P, whom I shall hereafter call by his own name, Dar Tarus, was the first to open his eyes; but he had not regained full consciousness when Gor Hajus showed signs of life.

I waited until both appeared quite restored. Dar Tarus was eyeing me with growing recognition that brought a most venomous expression of hatred to his countenance. Gor Hajus was frankly puzzled. The last he remembered was the scene in the death chamber at the instant that his executioner had run a sword through his heart. It was I who broke the silence.

"In the first place" I said, "let me tell you where you are, if you do not already know."

"I know well enough where I am," growled Dar Tarus.

"Ah!" exclaimed Gor Hajus, whose eyes had been roaming about the chamber. "I can guess where I am. What Toonolian has not heard of Ras Thavas? So they sold my corpse to the old butcher did they? And what now? Did I just arrive?"

"You have been here six years," I told him, "and you may stay here for ever unless we three can reach an agreement within the next few minutes, and that goes for you too, Dar Tarus."

"Six years!" mused Gor Hajus. "Well, out with it, man. What do you want? If it is to slay Ras Thavas, no! He has saved me from utter destruction; but name me some other, preferably Vobis Kan, Jeddak of Toonol. Find me a blade and I will slay a hundred to regain life."

"I seek the life of none unless he stands in the way of the fulfilment of my desire in this matter that I have in hand. Listen! Ras Thavas had here a beautiful Duhorian girl. He sold her body to Xaxa, Jeddara of Phundahl, transplanting the girl's brain to the wrinkled and hideous body of the Jeddara. It is my intention to regain the body, restore it to its own brain and return the girl to Duhor."

Gor Hajus grinned. "You have a large contract on your hands," he said, "but I can see that you are a man after my own heart and I am with you. It will give freedom and fighting, and all that I ask is a chance for one thrust at Vobis Kan."

"I promise you life," I replied; "but with the understanding that you serve me faithfully and none other, undertaking no business of your own, until mine has been carried to a successful conclusion."

"That means that I shall have to serve you for life," he replied, "for the thing you have undertaken you can never accomplish; but that is better than lying here on a cold ersite slab waiting for old Ras Thavas to come along and carve out my gizzard. I am yours! Let me up, that I may feel a good pair of legs under me again."

"And you?" I asked, turning to Dar Tarus as I released the bonds that held Gor Hajus. For the first time I now noticed that the ugly expression that I had first noted upon the face of Dar Tarus had given place to one of eagerness.

"Strike off my bonds!" he cried. "I will follow you to the ends of Barsoom and the way leads thus far to the fulfilment of your design; but it will not. It will lead to Phundahl and to the chamber of the wicked Xaxa, where, by the generosity of my ancestors, I may be given the opportunity to avenge the hideous wrong the creature did me. You could not have chosen one better fitted for your mission than Dar Tarus, one time soldier of the Jeddara's Guard, whom she had slain that in my former body one of her rotten nobles might woo the girl I loved."

A moment later the two men stood at my side, and without more delay I led them towards the runway that descended to the path beneath the building. As we went, I described to them the creature I had chosen to be the fourth member of our strange party. Gor Hajus questioned the wisdom of my choice, saying that the ape would attract too much attention to us. Dar Tarus, however, behaved that it might be helpful in many respects, since it was possible that we might be compelled to spend some time among the islands of the marshes which were often infested with these creatures; while, once in Phundahl, the ape might readily be used in the furtherance of our plans and would cause no considerable comment in a city where many of these beasts are held in captivity and often are seen performing for the edification of street crowds.

We went at once to the vault where the ape lay and where I had concealed the anaesthetized body of Valla Dia. Here I revived the great anthropoid and to my great relief found that the human half of its brain still was dominant. Briefly I explained my plan as I had to the other two and won the hearty promise of his support upon my engaging to restore his brain to its rightful place upon the completion of our venture.

First we must get off the island, and I outlined two plans I had in mind. One was to steal one of Ras Thavas' three fliers and set out directly for Phundahl, and the other, in the event that the first did not seem feasible, was to secrete ourselves aboard one of them on the chance that we might either overpower the crew and take over the ship after we had left the island, or escape undetected upon its arrival in Toonol. Dar Tarus liked the first plan; the ape, whom we now called by the name belonging to the human half of his brain, Hovan Du, preferred the first alternative of the second plan; and Gor Hajus the second alternative.

Dar Tarus explained that as our principal objective was Phundahl, the quicker we got there the better. Hovan Du argued that by seizing the ship after it had left the island we would have longer time in which to make our escape before the ship was missed and pursuit instituted, than by seizing it now in the full knowledge that its absence would be discovered within a few hours. Gor Hajus thought that it would be better if we could come into Toonol secretly and there, through one of his friends, secure arms and a flier of our own. It would never do, he insisted, to attempt to go far without arms for himself and Dar Tarus, nor could we hope to reach Phundahl without being overhauled by pursuers; for we must plan on the hypothesis that Ras Thavas would immediately discover my absence; that he would at once investigate; that he would find Dar Tarus and Gor Hajus missing and thereupon lose no time in advising Vobis Kan, Jeddak of Toonol, that Gor Hajus the assassin was at large, whereupon the Jeddak's best ships would be sent in pursuit.

Gor Hajus' reasoning was sound and coupled with my recollection that Ras Thavas had told me that his three ships were slow, I could readily foresee that our liberty would be of short duration were we to steal one of the old surgeon's fliers.

As we discussed the matter we had made our way through the Pits and I had found the exit to the tower. Silently we passed upward along the runway and out upon the roof. Both moons were winging low through the heavens and the scene was almost as light as day. If anyone was about discovery was certain. We hastened towards the hangar and were soon within it where, for a moment at least, I breathed far more easily than I had beneath those two brilliant moons upon the exposed roof.

The fliers were peculiar looking contrivances, low, squat, with rounded bows and stems and covered decks, their every line proclaiming them as cargo carriers built for anything but speed. One was much smaller than the other two and a second was evidently undergoing repairs. The third I entered and examined carefully. Gor Hajus was with me and pointed out several places where we might hide with little likelihood of discovery unless it were suspected that we might be aboard, and that of course constituted a very real danger; so much so that I had about decided to risk all aboard the small flier, which Gor Hajus assured me would be the fastest of the three, when Dar Tarus stuck his head into the ship and motioned me to come quickly.

"There is someone about," he said when I reached his side.

"Where?" I demanded.

"Come," he said, and led me to the rear of the hangar, which was flush with the wall of the building upon which it stood, and pointed through one of the windows into the inner garden where, to my consternation, I saw Ras Thavas walking slowly to and fro. For an instant I was sick with despair, for I knew that no ship could leave that roof unseen while anyone was abroad in the garden beneath, and Ras Thavas least of all people in the world; but suddenly a great light dawned upon me. I called the three close to me and explained my plan.

Instantly they grasped the possibilities in it and a moment later we had run the small flier out upon the roof and turned her nose toward the east, away from Toonol. Then Gor Hajus entered her, set the various controls as we had decided, opened the throttle, slipped back to the roof. The four of us hastened into the hangar and ran to the rear window where we saw the ship moving slowly and gracefully out over the garden and the head of Ras Thavas, whose ears must instantly have caught the faint purring of the motor, for he was looking up by the time we reached the window.

Instantly he hailed the ship and stepping back from the window that he might not see me I answered: "Good-bye, Ras Thavas! It is I, Vad Varo, going out into a strange world to see what it is like. I shall return. The spirits of your ancestors be with you until then."

That was a phrase I had picked up from reading in Ras Thavas' library and I was quite proud of it.

"Come back at once," he shouted up in reply, "or you will be with the spirits of your own ancestors before another day is done."

I made no reply. The ship was now at such a distance that I feared my voice might no longer seem to come from it and that we should be discovered. Without more delay we concealed ourselves aboard one of the remaining fliers, that upon which no work was being done, and there commenced as long and tiresome a period of waiting as I can recall ever having passed through.

I had at last given up any hope of the ship's being flown that day when I heard voices in the hangar, and presently the sound of footsteps aboard the flier. A moment later a few commands were given and almost immediately the ship moved slowly out into the open.

The four of us were crowded into a small compartment built into a tiny space between the forward and aft starboard buoyancy tanks. It was very dark and poorly ventilated, having evidently been designed as a storage closet to utilize otherwise waste space. We dared not converse for fear of attracting attention to our presence, and for the same reason we moved about as little as possible, since we had no means of knowing but that some member of the crew might be just beyond the thin door that separated us from the main cabin of the ship.

Altogether we were most uncomfortable; but the distance to Toonol is not so great but that we might hope that our situation would soon be changed—at least if Toonol was to be the destination of the ship. Of this we soon had cheering hope. We had been out but a short time when, faintly, we heard a hail and then the motors were immediately shut down and the ship stopped.

"What ship?" we heard a voice demand, and from aboard our own came the reply: "The Vosar, Tower of Thavas for Toonol." We heard a scraping as the other ship touched ours.

"We are coming aboard to search you in the name of Vobis Kan, Jeddak of Toonol. Make way!" shouted one from the other ship. Our cheer had been of short duration. We heard the shuffling of many feet and Gor Hajus whispered in my ear.

"What shall we do?" he asked.

I slipped my short-sword into his hand. "Fight!" I replied.

"Good, Vad Varo," he replied, and then I handed him my pistol and told him to pass it on to Dar Tarus. We heard the voices again, but nearer now.

"What ho!" cried one. "It is Bal Zak himself, my old friend Bal Zak!" "None other," replied a deep voice. "And whom did you expect to find in command of the Vosar other than Bal Zak?"

"Who could know but that it might have been this Vad Varo himself, or even Gor Hajus," said the other, "and our orders are to search all ships."

"I would that they were here," replied Bal Zak, "for the reward is high. But how could they, when Ras Thavas himself with his own eyes saw them fly off in the Pinsar before dawn this day and disappear in the east?"

"Right you are, Bal Zak," agreed the other, "and it were a waste of time to search your ship. Come men! to our own!" I could feel the muscles about my heart relax with the receding footfalls of Vobis Kan's warriors as they quitted the deck of the Vosar for their own ship, and my spirits rose with the renewed purring of our own motor as Ras Thavas' flier again got under way. Gor Hajus bent his lips close to my ear.

"The spirits of our ancestors smile upon us," he whispered. "It is night and the darkness will aid in covering our escape from the ship and the landing stage."

"What makes you think it is night?" I asked.

"Vobis Kan's ship was close by when it hailed and asked our name. By daylight it could have seen what ship we were."

He was right. We had been locked in that stuffy hole since before dawn, and while I had thought that it had been for a considerable time, I also had realized that the darkness and the inaction and the nervous strain would tend to make it seem much longer than it really had been; so that I would not have been greatly surprised had we made Toonol by daylight.

The distance from the Tower of Thavas to Toonol is inconsiderable, so that shortly after Vobis Kan's ship had spoken to us we came to rest upon the landing stage at our destination. For a long time we waited, listening to the sounds of movement aboard the ship and wondering, upon my part at least, as to what the intentions of the captain might be. It was quite possible that Bal Zak might return to Thavas this same night, especially if he had come to Toonol to fetch a rich or powerful patient to the laboratories; but if he had come only for supplies he might well lie here until the morrow. This much I had learned from Gor Hajus, my own knowledge of the movements of the fliers of Ras Thavas being considerably less than nothing; for, though I had been months a lieutenant of the master surgeon, I had learned only the day before of the existence of his small fleet, it being according to the policy of Ras Thavas to tell me nothing unless the telling of it coincided with and furthered his own plans.

Questions which I asked he always answered, if he reasoned that the effects would not be harmful to his own interests, but he volunteered nothing that he did not particularly wish me to know; and the fact that there were no windows in the outside walls of the building facing towards Toonol, that I had never before the previous day been upon the roof and that I never had seen a ship sail over the inner court towards the east all tended to explain my ignorance of the fleet and its customary operations.

We waited quietly until silence fell upon the ship, betokening either that the crew had retired for the night or that they had gone down into the city. Then, after a whispered consultation with Gor Hajus, we decided to make an attempt to leave the flier. It was our purpose to seek a hiding place within the tower of the landing stage from which we might investigate possible avenues of escape into the city, either at once or upon the morrow when we might more easily mix with the crowd that Gor Hajus said would certainly be in evidence from a few hours after sunrise.

Cautiously I opened the door of our closet and looked into the main cabin beyond. It lay in darkness. Silently we filed out. The silence of the tomb lay upon the flier, but from far below arose the subdued noises of the city. So far, so good! Then, without sound, without warning, a burst of brilliant fight illuminated the interior of the cabin. I felt my fingers tighten upon my sword-hilt as I glanced quickly about.

Directly opposite us, in the narrow doorway of a small cabin, stood a tall man whose handsome harness betokened the fact that he was no common warrior. In either hand he held a heavy Barsoomian pistol, into the muzzles of which we found ourselves staring.

Chapter 9 HANDS UP!

In quiet tones he spoke the words of the Barsoomian equivalent of our Earthly hands up! The shadow of a grim smile touched his lips, and as he saw us hesitate to obey his commands he spoke again.

"Do as I tell you and you will be well off. Keep perfect silence. A raised voice may spell your doom; a pistol shot most assuredly."

Gor Hajus raised his hands above his head and we others followed his example.

"I am Bal Zak," announced the stranger. My heart slumped.

"Then you had better commence firing," said Gor Hajus, "for you will not take us alive and we are four to one."

"Not so fast, Gor Hajus," admonished the captain of the Vosar, until you learn what is in my mind."

"That, we already know for we heard you speak of the large reward that awaited the captor of Vad Varo and Gor Hajus," snapped the assassin of Toonol.

"Had I craved that reward so much I could have turned you over to the dwar of Vobis Kan's ship when he boarded us," said Bal Zak.

"You did not know we were aboard the Vosar," I reminded him.

"Ah, but I did."

Gor Hajus snorted his disbelief.

"How then," Bal Zak reminded us, "was I able to be ready upon this very spot when you emerged from your hiding place? Yes, I knew that you were aboard."

"But how?" demanded Dar Tarus.

"It is immaterial," replied Bal Zak, "but to satisfy your natural curiosity I will tell you that I have quarters in a small room in the Tower of Thavas, my windows overlook the roof and the hangar. My long life spent aboard fliers has made me very sensitive to every sound of a ship-motors changing their speed will awaken me in the dead of night, as quickly as will their starting or their stopping. I was awakened by the starting of the motors of the Pinsar; I saw three of you upon the roof and the fourth drop from the deck of the flier as she started and my judgment told me that the ship was being sent out unmanned for some reason of which I had no knowledge. It was too late for me to prevent the act and so I waited in silence to learn what would follow. I saw you hasten into the hangar and I heard Ras Thavas' hail and your reply, and then I saw you board the Vosar. Immediately I descended to the roof and ran noiselessly to the hangar, apprehending that you intended making away with this ship; but there was no one about the controls; and from a tiny port in the control room, through which one has a view of the main cabin, I saw you enter the closet. I was at once convinced that your only purpose was to stow away for Toonol and consequently, aside from keeping an eye upon your hiding place, I went about my business as usual."

"And you did not advise Ras Thavas?" I asked.

"I advised no one," he replied. "Years ago I learned to mind my own business, to see all, to hear all and to tell nothing unless it profited me to do so."

"But you said that the reward is high for our apprehension," Gor Hajus reminded him. "Would it not be profitable to collect it?"

"There are in the breasts of honourable men," replied Bal Zak, "forces that rise superior to the lust for gold, and while Toonolians are supposedly a people free from the withering influences of sentiment yet I for one am not totally unconscious of the demand of gratitude. Six years ago, Gor Hajus, you refused to assassinate my father, holding that he was a good man, worthy to live and one that had once befriended you slightly. To-day, through his son, you reap your reward and in some measure are repaid for the punishment that was meted out to you by Vobis Kan because of your refusal to slay the sire of Bal Zak. I have sent my crew away that none aboard the Vosar but myself might have knowledge of your presence. Tell me your plans and command me in what way I may be of further service to you."

"We wish to reach the streets, unobserved," replied Gor Hajus. "Can you but help us in that we shall not put upon your shoulders further responsibility for our escape. You have our gratitude and in Toonol, I need not remind you, the gratitude of Gor Hajus is a possession that even the Jeddak has craved."

"Your problem is complicated," said Bal Zak, after a moment of thought, "by the personnel of your party. The ape would immediately attract attention and arouse suspicion. Knowing much of Ras Thavas' experiments I realized at once this morning, after watching him with you, that he had the brain of a man; but this very fact would attract to him and to you the closer attention of the masses."

"I do not need acquaint them with the fact," growled Hovan Du. "To them I need be but a captive ape. Are such unknown in Toonol?"

"Not entirely, though they are rare," replied Bal Zak. "But there is also the white skin of Vad Varo! Ras Thavas appears to have known nothing of the presence of the ape with you; but he full well knew of Vad Varo, and your description has been spread by every means at his command. You would be recognized immediately by the first Toonolian that lays eyes upon you, and then there is Gor Hajus. He has been as dead for six years, yet I venture there is scarce a Toonolian that broke the shell prior to ten years ago who does not know the face of Gor Hajus as well as he knows that of his own mother. The Jeddak himself was not better known to the people of Toonol than Gor Hajus. That leaves but one who might possibly escape suspicion and detection in the streets of Toonol."

"If we could but obtain weapons for these others," I suggested, "we might even yet reach the house of Gor Hajus' friend."

"Fight your way through the city of Toonol?" demanded Bal Zak.

"If there is no other way we should have to," I replied.

"I admire the will," commented the commander of the Vosar, "but fear that the flesh is without sufficient strength. Wait! there is a way— perhaps. On the stage just below this there is a public depot where equilibrimotors are kept and rented. Could we find the means to obtain four of these there would be a chance, at least, for you to elude the air patrols and reach the house of Gor Hajus' friend; and I think I see a way to the accomplishment of that. The landing tower is closed for the night but there are several watchmen distributed through it at different levels. There is one at the equilibrimotor depot and, as I happen to know, he is a devotee of jetan. He would rather play jetan than attend to his duties as watchman. I often remain aboard the Vosar at night and occasionally he and I indulge in a game. I will ask him up to-night and while he is thus engaged you may go to the depot, help yourselves to equilibrimotors and pray to your ancestors that no air patrol suspects you as you cross the city towards your destination. What think you of this plan, Gor Hajus?"

"It is splendid," replied the assassin. "And you, Vad Varo?"

"If I knew what an equilibrimotor is I might be in a better position to judge the merits of the plan," I replied. "However, I am satisfied to abide by the judgment of Gor Hajus. I can assure you, Bal Zak, of our great appreciation, and as Gor Hajus has put the stamp of his approval upon your plan I can only urge you to arrange that we may put it into effect with as little delay as possible."

"Good!" exclaimed Bal Zak. "Come with me and I will conceal you until I have lured the watchman to the jetan game within my cabin. After that your fate will be in your own hands."

We followed him from the ship on to the deck of the landing stage and close under the side of the Vosar opposite that from which the watchman must approach the ship and enter it. Then, bidding us good luck, Bal Zak departed.

From the summit of the landing tower I had my first view of a Martian city.

Several hundred feet below me lay spread the broad, well-lighted avenues of Toonol, many of which were crowded with people. Here and there, in this central district, a building was raised high upon its supporting, cylindrical metal shaft; while further out, Where the residences predominated, the city took on the appearance of a colossal and grotesque forest. Among the larger palaces only an occasional suite of rooms was thus raised high above the level of the others, these being the sleeping apartments of the owners, their servants or their guests; but the smaller homes were raised in their entirety, a precaution necessitated by the constant activities of the followers of Gor Hajus' ancient profession that permitted no man to be free from the constant menace of assassination. Throughout the central district the sky was pierced by the lofty towers of several other landing stages; but, as I was later to learn, these were comparatively few in number. Toonol is in no sense a flying nation, supporting no such enormous fleets of merchant ships and vessels of war as, for example, the twin cities of Helium or the great capital of Ptarth.

A peculiar feature of the street lighting of Toonol, and in fact the same condition applies to the fighting of other Barsoomian cities I have visited, I noted for the first time that night as I waited upon the landing stage for the return of Bal Zak with the watchman. The luminosity below me seemed confined directly to the area to be lighted; there was no diffusion of light upward or beyond the limits the lamps were designed to light This was effected, I was told, by lamps designed upon principles resulting from ages of investigation of the properties of light waves and the laws governing them which permit Barsoomian scientists to confine and control light as we confine and control matter. The light waves leave the lamp, pass along a prescribed circuit and return to the lamp. There is no waste nor, strange this seemed to me, are there any dense shadows when lights are properly installed and adjusted, for the waves in passing around objects to return to the lamp, illuminate all sides of them.

The effect of this lighting from the great height of the tower was rather remarkable. The night was dark, there being no moons at that hour upon this night, and the effect was that obtained when sitting in a darkened auditorium and looking upon a brilliantly lighted stage. I was still intent upon watching the life and colour beneath when we heard Bal Zak returning. That he had been successful in his mission was apparent from the fact that he was conversing with another.

Five minutes later we crept quietly from our hiding place and descended to the stage below where lay the equilibrimotor depot. As theft is practically unknown upon Barsoom, except for purposes entirely disassociated from a desire to obtain pecuniary profit through the thing stolen, no precautions are taken against theft. We therefore found the doors of the depot open and Gor Hajus and Dar Tarus quickly selected four equilibrimotors and adjusted them upon us. They consist of a broad belt, not unlike the life belt used aboard trans-oceanic liners upon Earth; these belts are filled with the eighth Barsoomian ray, or ray of propulsion, to a sufficient degree to just about equalize the pull of gravity and thus to maintain a person in equilibrium between that force and the opposite force exerted by the eighth ray. Permanently attached to the back of the belt is a small radium motor, the controls for which are upon the front of the belt.

Rigidly attached to and projecting from each side of the upper rim of the belt is a strong, light wing with small hand levers for quickly altering its position.

Gor Hajus quickly explained the method of control, but I could apprehend that there might be embarrassment and trouble awaiting me before I mastered the art of flying in an equilibrimotor. He showed me how to tilt the wings downward in walking so that I would not leave the ground at every step, and thus he led me to the edge of the landing stage.

"We will rise here," he said, "and keeping in the darkness of the upper levels seek to reach the house of my friend without being detected. If we are pursued by air patrols we must separate; and later those who escape may gather just west of the city wall where you will find a small lake with a deserted tower upon its northern rim—this tower will be our rendezvous in event of trouble. Follow me!" He started his motor and rose gracefully into the air.

Hovan Du followed him and then it was my turn. I rose beautifully for about twenty feet, floating out over the city which lay hundreds of feet below, and then, quite suddenly, I turned upside down. I had done something wrong—I was quite positive of it. It was a most startling sensation, I can assure you, floating there with my head down, quite helpless; while below me lay the streets of a great city and no softer, I was sure, than the streets of Los Angeles or Paris. My motor was still going, and as I manipulated the controls which operated the wings I commenced to describe all sorts of strange loops and spirals and spins; and then Dar Tarus came to my rescue. First he told me to lie quietly and then directed the manipulation of each wing until I had gained an upright position. After that I did fairly well and was soon rising in the wake of Gor Hajus and Hovan Du.

I need not describe in detail the hour of flying, or rather floating, that ensued. Gor Hajus led us to a considerable altitude and there, through the darkness above the city, our slow motors drove us towards a district of magnificent homes surrounded by spacious grounds; and here, as we hovered over a large palace, we were suddenly startled by a sharp challenge coming from directly above us.

"Who flies by night?" a voice demanded.

"Friends of Mu Tel, Prince of the House of Kan," replied Gor Hajus: quickly.

"Let me see your night flying permit and your flier's licence," ordered the one above us, at the same time swooping suddenly to our level and giving me my first sight of a Martian policeman. He was equipped with a much swifter and handier equilibrimotor than ours. I think that was the first fact to impress us deeply, and it demonstrated the futility of flight; for he could have given us ten minutes start and overhauled each of us within another ten minutes, even though we had elected to fly in different directions. The fellow was a warrior rather than a policeman, though detailed to duty such as our Earthly police officers perform; the city being patrolled both day and night by the warriors of Vobis Kan's army.

He dropped now close to the assassin of Toonol, again demanding permit and licence and at the same time flashing a light in the face of my comrade.

"By the sword of the Jeddak!" he cried. "Fortune heaps her favors upon me. Who would have thought an hour since that it would be I who would collect the reward for the capture of Gor Hajus?"

"Any other fool might have thought it," returned Gor Hajus, "but he would have been as wrong as you," and as he spoke he struck with the short-sword I had loaned him.

The blow was broken by the wing of the warrior's equilibrimotor, which it demolished, yet it inflicted a severe wound in the fellow's shoulder. He tried to back off, but the damaged wing caused him only to wheel around erratically; and then he seized upon his whistle and attempted to blow a mighty blast that was cut short by another blow from Gor Hajus' sword that split the man's head open to the bridge of his nose.

"Quick!" cried the assassin. "We must drop into the gardens of Mu Tel, for that signal will bring a swarm of air patrols about our heads."

The others I saw falling rapidly towards the ground, but again I had trouble.

Depress my wings as I would I moved only slightly downward and upon a path that, if continued, would have landed me at a considerable distance from the gardens of Mu Tel. I was approaching one of the elevated portions of the palace, what appeared to be a small suite that was raised upon its shining metal shaft far above the ground. From all directions I could hear the screaming whistles of the air patrols answering the last call of their comrade whose corpse floated just above me, a guide even in death to point the way for his fellows to search us out. They were sure to discover him and then I would be in plain view, of them and my fate sealed.

Perhaps I could find ingress to the apartment looming darkly near! There I might hide until the danger had passed, provided I could enter, undetected. I directed my course towards the structure; an open window took form through the darkness and then I collided with a fine wire netting—I had run into a protecting curtain that fends off assassins of the air from these high-flung sleeping apartments. I felt that I was lost. If I could but reach the ground I might find concealment among the trees and shrubbery that I had seen vaguely outlined beneath me in the gardens of this Barsoomian prince; but I could not drop at a sufficient angle to bring me to ground within the garden, and when I tried to spiral down I turned over and started up again. I thought of ripping open my belt and letting the eighth ray escape; but in my unfamiliarity with this strange force I feared that such an act might precipitate me to the ground with too great violence, though I was determined to have recourse to it as a last alternative if nothing less drastic presented itself.

In my last attempt to spiral downward I rose rapidly feet foremost to a sudden and surprising collision with some object above me. As I frantically righted myself, fully expecting to be immediately seized by a member of the air patrol, I found myself face to face with the corpse of the warrior Gor Hajus had slain.

The whistling of the air patrols sounded ever nearer—it could be only a question of seconds now before I was discovered—and with the stern necessity that confronted me, with death looking me in the face, there burst upon me a possible avenue of escape from my dilemma.

Seizing tightly with my left hand the harness of the dead Toonolian, I whipped out my dagger and slashed his buoyancy belt a dozen times. Instantly, as the rays escaped, his body started to drag me downward, Our descent was rapid, but not precipitate, and it was but a matter of seconds before we landed gently upon the scarlet sward of the gardens of Mu Tel, Prince of the House of Kan, close beside a clump of heavy shrubbery. Above me sounded the whistles of the circling patrols as I dragged the corpse of the warrior into the concealing depth of the foliage. Nor was I an instant too soon for safety, as almost immediately the brilliant rays of a searchlight shot downward from the deck of a small patrol ship, illuminating the open spaces of the garden all about me. A hurried glance through the branches and the leaves of my sanctuary revealed nothing of my companions and I breathed a sigh of relief in the thought that they, too, had found concealment.

The light played for a short time about the gardens and then passed on, as did the sound of the patrol's whistles, as the search proceeded elsewhere; thus giving me the assurance that no suspicion was directed upon our hiding place.

Left in darkness I appropriated such of the weapons of the dead warrior as I coveted, after having removed my equilibrimotor, which I was first minded to destroy, but which I finally decided to moor to one of the larger shrubs against the possibility that I might again have need for it; and now, secure in the conviction that the danger of discovery by the air patrol had passed, I left my concealment and started in search of my companions.

Keeping well in the shadows of the trees and shrubs I moved in the direction of the main building, which loomed darkly near at hand; for in this direction I believed Gor Hajus would lead the others as I knew that the palace of Mu Tel was to have been our destination. As I crept along, moving with utmost stealth, Thuria, the nearer moon, shot suddenly above the horizon, illuminating the night with her brilliant rays. I was close to the building's ornately carved wall at the moment; beside me was a narrow niche, its interior cast in deepest shadow by Thuria's brilliant rays; to my left was an open bit of lawn upon which, revealed in every detail of its terrifying presence, stood as fearsome a creature as my Earthly eyes ever had rested upon. It was a beast about the size of a Shetland pony, with ten short legs and a terrifying head that bore some slight resemblance to that of a frog, except that the jaws were equipped with three rows of long, sharp tusks.

The thing had its nose in the air and was sniffing about, while its great pop eyes moved swiftly here and there, assuring me, beyond the shadow of a doubt, that it was searching for someone. I am not inclined to be egotistical, yet I could not avoid the conviction that it was searching for me. It was my first experience of a Martian watch dog; and as I sought concealment within the dark shadows of the niche behind me, at the very instant that the creature's eyes alighted upon me, and heard his growl and saw him charge straight towards me, I had a premonition that it might prove my last experience with one.

I drew my long-sword as I backed into the niche, but with a sense of the utter inadequacy of the unaccustomed weapon in the face of this three or four hundred pounds of ferocity incarnate. Slowly I backed away into the shadows as the creature bore down upon me and then, as it entered the niche, my back collided with a solid obstacle that put an end to further retreat.
