Chapter VI: Part 6

The great bag, almost as large as the room in which we had been confined, bellied above us. It strained upon its guy ropes in its impatience to be aloft until I wondered that they held, and then I gave the word.

Simultaneously Nur An slipped his knot and I severed the rope upon the opposite side. Freed, the great bag leaped aloft, snapping us in its wake. It shot upward with a velocity that was astounding until the valley of Hohr was but a little hollow in the surface of the great world that lay below us.

Presently a wind caught us and you may be assured that we gave thanks to our ancestors as we realized that we were at last drifting from above the cruel city of Ghasta. The wind increased until it was blowing rapidly in a northeasterly direction, but little did we care where it wafted us as long as it took us away from the river Syl and the valley of Hohr.

After we had passed beyond the crater of the ancient volcano, which formed the bed of the valley in which lay somber Ghasta, we saw below us, in the moonlight, a rough volcanic country that presented a weird and impressive appearance of unreality; deep chasms and tumbled piles of basalt seemed to present an unsurmountable barrier to man, which may explain why in this remote and desolate corner of Barsoom the valley of Hohr had lain for countless ages undiscovered.

The wind increased. Floating at a great altitude we were being carried at considerable speed, yet I could see that we were very slowly falling as the hot air within our bag cooled. How much longer it would keep us up I could not guess, but I hoped it would bear us at least beyond the uninviting terrain beneath us.

With the coming of dawn we were floating but a few hundred feet above the ground; the volcanic country was far behind us and as far as we could see stretched lovely, rolling hills, sparsely timbered with the drought resisting skeel upon which it has been said the civilization of Barsoom has been erected.

As we topped a low hill, passing over it by a scant fifty sofads, we saw below us a building of gleaming white. Like all the cities and isolated buildings of Barsoom, it was surrounded by a lofty wall, but in other respects it differed materially from the usual Barsoomian type of architecture. The edifice, which was made up of a number of buildings, was not surmounted by the usual towers, domes and minarets that mark all Barsoomian cities and which only in recent ages have been giving away slowly to the flat landing stages of an aerial world. The structure below us was composed of a number of flat roofed buildings of various heights, none of which, however, appeared to rise over four levels. Between the buildings and the outer walls and in several open courts between the buildings, there was a profusion of trees and shrubbery with scarlet sward and well kept paths. It was, in fact, a striking and beautiful sight, yet having so recently been lured to near destruction by the beauties of Hohr and the engaging allurements of her beautiful women, we had no mind to be deceived again by external appearances. We would float over the palace of enchantment and take our chances in the open country beyond.

But fate willed otherwise. The wind had abated; we were dropping rapidly; beneath us we saw people in the garden of the building and simultaneously, as they discovered us, it was evident that they were filled with consternation. They hastened quickly to the nearest entrances and there was not a human being in sight when we finally came to rest upon the roof of one of the taller sections of the structure.

As we extricated ourselves from the loops in which we had been sitting, the great bag, relieved of our weight, rose quickly into the air for a short distance, turned completely over and dropped to the ground just beyond the outer wall. It had served us well and now it seemed like a living thing that had given up its life for our salvation.

We were to have little time, however, for sentimental regrets, for almost immediately a head appeared through a small opening in the roof upon which we stood. The head was followed by the body of a man, whose harness was so scant as to leave him almost nude. He was an old man with a finely shaped head, covered with scant, gray locks.

Apparent physical old age is so rare upon Barsoom as always to attract immediate attention. In the natural span of life we live often to a thousand years, but during that long period our appearance seldom changes but little. It is true that most of us meet violent death long before we reach old age, but there are some who pass the allotted span of life and others who do not care for themselves so well and these few constitute the physically old among us; evidently of such was the little old man who confronted us.

At sight of him Nur An voiced an exclamation of pleased surprise. "Phor Tak!" he cried.

"Heigh-oo!" cackled the old man in a high falsetto. "Who cometh from the high heavens who knows old Phor Tak?"

"It is I--Nur An!" exclaimed my friend.

"Heigh-oo!" cried Phor Tak. "Nur An--one of Tul Axtar's pets."

"As you once were, Phor Tak."

"But not now--not now," almost screamed the old man. "The tyrant squeezed me like some juicy fruit and then cast the empty rind aside. Heigh-oo! He thought it was empty, but I pray daily to all my ancestors that he may live to know that he was wrong. I can say this with safety to you, Nur An, for I have you in my power and I promise you that you shall never live to carry word of my whereabouts to Tul Axtar."

"Do not fear, Phor Tak," said Nur An. "I, too, have suffered from the villainy of the Jeddak of Jahar. You were permitted to leave the capital in peace, but all my property was confiscated and I was sentenced to death."

"Heigh-oo! Then you hate him, too," exclaimed the old man.

"Hate is a weak word to describe my feeling for Tul Axtar," replied my friend.

"It is well," said Phor Tak. "When I saw you descending from the skies I thought that my ancestors had sent you to help me, and now I know that it was indeed true. Be this another warrior from Jahar?" he added, nodding his old head toward me.

"No, Phor Tak," replied Nur An. "This is Hadron of Hastor, a noble of Helium, but he, too, has been wronged by Jahar."

"Good!" exclaimed the old man. "Now there are three of us. Heretofore I have had only slaves and women to assist me, but now with two trained warriors, young and strong, the goal of my triumph appears almost in sight."

As the two men conversed I had recalled that part of the story that Nur An had told me in the pits of Tjanath which related to Phor Tak and his invention of the rifle that projected the disintegrating rays which had proved so deadly against the patrol boat above Helium the night of Sanoma Tora's abduction. Strange, indeed, was fate that it should have brought me into the palace of the man who held the secret that might mean so much to Helium and to all Barsoom. Strange, too, and devious had been the path along which fate had led me, yet I knew that my ancestors were guiding me and that all must have been arranged to some good end.

When Phor Tak had heard only a portion of our story he insisted that we must be both fatigued and hungry and, like the good host that he proved to be, he conducted us down to the interior of his palace and, summoning slaves, ordered that we be bathed and fed and then permitted to retire until we were rested. We thanked him for his kindness and consideration, of which we were glad to avail ourselves.

The days that followed were both interesting and profitable. Phor Tak, surrounded only by a few faithful slaves who had followed him into his exile, was delighted with our company and with the assistance which we could give him in his experiment, which, once assured of our loyalty, he explained to us in detail.

He told us the story of his wanderings after he had left Jahar and of how he had stumbled upon this long deserted castle, whose builder and occupants had left no record other than their bones. He told us that when he discovered it skeletons had strewn the courtyard and in the main entrance were piled the bones of a score of warriors, attesting the fierce defense that the occupants had waged against some unknown enemy, while in many of the upper rooms he had found other skeletons--the skeletons of women and children.

"I believe," he said, "that the place was beset by members of some savage horde of green warriors that left not a single survivor. The courts and gardens were overgrown with weeds and the interior of the building was filled with dust, but otherwise little damage had been done. I call it Jhama, and here I am carrying on my life's work."

"And that?" I asked.

"Revenge upon Tul Axtar," said the old man. "I gave him the disintegrating ray; I gave him the insulating paint that protects his own ships and weapons from it, and now some day I shall give him something else--something that will be as revolutionary in the art of war as the disintegrating ray itself; something that will cast the fleet of Jahar broken wrecks upon the ground; something that will search out the palace of Tul Axtar and bury the tyrant beneath its ruins."

We had not been long at Jhama before both Nur An and I became convinced that Phor Tak's mind was at least slightly deranged from long brooding over the wrongs inflicted upon him by Tul Axtar; though naturally possessed of a kindly disposition he was obsessed by a maniacal desire to wreak vengeance upon the tyrant with utter disregard of the consequences to himself and to others. Upon this single subject he was beyond the influence of reason and having established to his own satisfaction that Nur An and I were potential factors in the successful accomplishment of his design, he would fly into a perfect frenzy of rage whenever I broached the subject of our departure.

Fretting as I was beneath the urge to push on to Jahar and the rescue of Sanoma Tora, I could but illy brook this enforced delay, but Phor Tak was adamant--he would not permit me to depart--and the absolute loyalty of his slaves made it possible for him to enforce his will. In our hearing he explained to them that we were guests, honored guests as long as we made no effort to depart without his permission, but should they discover us in an attempt to leave Jhama surreptitiously they were to destroy us.

Nur An and I discussed the matter at length. We had discovered that four thousand haads of difficult and unfriendly country lay between us and Jahar. Being without a ship and without thoats there was little likelihood that we should be able to reach Jahar in time to be of service to Sanoma Tora, if we ever reached it at all, and so we agreed to bide our time, impressing Phor Tak with our willingness to aid him in the hope that eventually we should be able to enlist his aid and support, and so successful were we that within a short time we had so won the confidence of the old scientist that we began to entertain hope that he would take us into his innermost confidence and reveal the nature of the instrument of destruction which he was preparing for Tul Axtar.

I must admit that I was principally interested in his invention because I was confident that in order to utilize it against Tul Axtar he must find some means of transporting it to Jahar and in this I saw an opportunity for reaching the capital of the tyrant myself.

We had been in Jhama about ten days during which time Phor Tak exhibited signs of extreme nervousness and irritability. He kept us with him practically all of the time that he was not closeted in the innermost recesses of his secret laboratory.

During the evening meal upon the tenth day Phor Tak seemed more distraught than ever. Talking, as usual, interminably about his hatred of Tul Axtar, his countenance assumed an expression of maniacal fury.

"But I am helpless," he almost screamed at last. "I am helpless because there is no one to whom I may entrust my secret, who also has the courage and intelligence to carry out my plan. I am too old, too weak to undergo the hardships that would mean nothing to young men like you, but which must be undergone if I am to fulfill my destiny as the savior of Jahar. If I could but trust you! If I could but trust you!"

"Perhaps you can, Phor Tak," I suggested.

The words or my tone seemed to soothe him. "Heigh-oo!" he exclaimed. "Sometimes I almost think that I can."

"We have a common aim," I said; "or at least different aims which converge at the same point--Jahar. Let us work together then. We wish to reach Jahar. If you can help us, we will help you."

He sat in silent thought for a long moment. "I'll do it," he said. "Heigh-oo! I'll do it. Come," and rising from his chair he led us toward the locked doorway that barred the entrance to his secret laboratory.

THE FLYING DEATH

Phor Tak's laboratory occupied an entire wing of the building and consisted of a single, immense room fully fifty feet in height. His benches, tables, instruments and cabinets, located in one corner, were lost in the great interior. Near the ceiling and encircling the room was a single track from which was suspended a miniature cruiser, painted the ghastly blue of Jahar. Upon one of the benches was a cylindrical object about as long as one's hand. These were the only noticeable features of the laboratory other than its immense emptiness.

As Phor Tak ushered us within he closed the door behind him and I heard the ominous click of the ponderous lock. There was something depressing in the suggestiveness of the situation induced, perhaps, by our knowledge that Phor Tak was mad and accentuated by the eerie mystery of the vasty chamber.

Leading us to the bench upon which lay the cylindrical object which had attracted my attention, he lifted it carefully, almost caressingly, from its resting place. "This," he said, "is a model of the device that will destroy Jahar. In it you behold the concentrated essence of scientific achievement. In appearance it is but a small metal cylinder, but within it is a mechanism as delicate and as sensitive as the human brain and you will perceive that it functions almost as though animated by a mind within itself, but it is purely mechanical and may be produced in quantities quickly and at low cost. Before I explain it further I shall demonstrate one phase of its possibilities. Watch!"

Still holding the cylinder in his hand, Phor Tak stepped to a shallow cabinet against the wall and opening it revealed an elaborate equipment of switches, levers and push buttons. "Now watch the miniature flier suspended from the track near the ceiling," he directed, at the same time closing a switch. Immediately the flier commenced to travel along the track at considerable speed. Now Phor Tak pressed a button upon the top of the cylinder, which immediately sped from his extended palm, turned quickly in the air and rushed straight for the speeding flier. Slowly the distance between the two closed; the cylinder, curving gradually into the line of flight of the flier, was now trailing directly behind it, its pointed nose but a few feet from the stern of the miniature ship. Then Phor Tak pulled a tiny lever upon his switchboard and the flier leaped forward at accelerated speed. Instantly the speed of the cylinder increased and I could see that it was gaining in velocity much more rapidly than the flier. Half way around the room again its nose struck the stern of the fleeing craft with sufficient severity to cause the ship to tremble from stem to stern; then the cylinder fell away and floated gently toward the floor. Phor Tak opened a switch that stopped the flier in its flight and then, running forward, caught the descending cylinder in his hand.

"This model," he explained, as he returned to where we stood, "is so constructed that when it makes contact with the flier it will float gently downward to the floor, but as you have doubtless fully realized ere this, the finished product in practical use will explode upon contact with the ship. Note these tiny buttons with which it is covered. When any one of these comes in contact with an object the model stops and descends, whereas the full sized device, properly equipped, will explode, absolutely demolishing whatever it may have come in contact with. As you are aware every substance in the universe has its own fixed vibratory rate. This mechanism can be so attuned as to be attracted by the vibratory rate of any substance. The model, for example, is attracted by the blue protective paint with which the flier is covered. Imagine a fleet of Jaharian warships moving majestically through the air in battle formation. From an enemy ship or from the ground and at a distance so far as to be unobservable by the ships of Jahar, I release as many of these devices as there are ships in the fleet, allowing a few moments to elapse between launchings. The first torpedo rushes toward the fleet and destroys the nearest ship. All the torpedoes in the rear, strung out in line, are attracted by the combined masses of all the blue protecting coverings of the entire fleet. The first ship is falling to the ground and though all of its paint may not have been destroyed, it has not the power to deflect any of the succeeding torpedoes, which one by one destroy the nearest of the remaining ships until the fleet has been absolutely erased. I have destroyed a great fleet without risking the life of a single man of my own following."

"But they will see the torpedoes coming," suggested Nur An, "and they will devise some defense. Even gunfire might stop many of them."

"Heigh-oo! But I have thought of that," cackled Phor Tak. He laid the torpedo upon a bench and opened another cabinet.

In this cabinet were a number of receptacles, some tightly sealed and others opened, revealing their contents which appeared to be different colored paints. From a number of these receptacles protruded the handles of paint brushes. One such handle, however, appeared to hang in mid-air, a few inches above one of the shelves, while just beneath it was a section of the rim of a receptacle that also appeared to be resting upon nothing. Phor Tak placed his open hand directly beneath this floating rim and when he removed his hand from the cabinet, the rim of the receptacle and the portion of the handle of the paint brush, floating just above it, followed, hovering just over his extended fingers, which were cupped in the position that they might assume were they holding a glass jar, such as would ordinarily have belonged to a rim like that which I could see floating about an inch above his fingers.

Going to the bench where he had laid the cylinder, Phor Tak went through the motions of setting a jar upon it, and, though there was no jar visible other than the floating rim, I distinctly heard a noise that was identical with the sound which the bottom of a glass jar would have made in coming in contact with the bench.

I can assure you that I was greatly mystified, but still more so by the events immediately following. Phor Tak seized the handle of the paint brush and made a pass a few inches above the metal torpedo. Instantly a portion of the torpedo, about an inch wide and three or four inches long, disappeared. Pass after pass he made until finally the whole surface of the torpedo had disappeared. Where it had rested the bench was empty. Phor Tak returned the handle of the paint brush to its floating position just above the floating jar rim and then he turned to us with an expression of child-like pride upon his face, as much to say, "Well, what do you think of that? Am I not wonderful?" And I was certainly forced to concede that it was wonderful and that I was entirely baffled and mystified by what I had seen.

"There, Nur An," exclaimed Phor Tak, "is the answer to your criticism of The Flying Death."

"I do not understand," said Nur An with a puzzled expression upon his face.

"Heigh-oo!" cried Phor Tak. "Have you not seen me render the device invisible?"

"But it is gone," said Nur An.

Phor Tak laughed his high cackling laugh. "It is still there," he said, "but you cannot see it. Here," and he took Nur An's hand and guided it toward the spot where the device had been.

I could see Nur An's fingers apparently feeling over the surface of something several inches above the top of the table. "By my first ancestor, it is still there!" he exclaimed.

"It is wonderful," I exclaimed. "You did not even touch it; you merely made passes above it with the handle of a paint brush and it disappeared."

"But I did touch it," insisted Phor Tak. "The brush was there, but you did not see it because it was covered by the substance which renders The Flying Death invisible. Notice this transparent glass receptacle in which I keep the compound of invisibility and all that you can see of it is that part of the rim which, by chance, has not been coated with the compound."

"Marvellous!" I exclaimed. "Even now, although I have witnessed it with my own eyes I can scarce conceive of the possibility of such a miracle."

"It is no miracle," said Phor Tak. "It is merely the application of scientific principles well known to me for hundreds of years. Nothing moves in straight lines; light, vision, electro-magnetic forces follow lines that curve. The compound of invisibility merely bows outward the reflected light, which, entering our eyes and impinging upon our optic nerves, results in the phenomenon which we call vision, so that they pass around any object which is coated with the compound. When I first started to apply the compound to The Flying Death, your line of vision was deflected around the small portions so coated, but when I coated the entire surface of the torpedo, the curve of your vision passed completely around it on both sides so that you could plainly see the bench upon which it was resting precisely as though the device had not been there."

I was astounded at the apparent simplicity of the explanation, and, naturally, being a soldier, I saw the tremendous advantage that the possession of these two scientific secrets would impart to the nation which controlled them. For the safety; yes, for the very existence of Helium, I must possess them and if that were impossible, then Phor Tak must be destroyed before the secret of this infernal power could be passed on to any other nation. Perhaps I could so ingratiate myself with old Phor Tak as to be able to persuade him to turn these secrets over to Helium in return for Helium's assistance in the work of wreaking his vengeance upon Tul Axtar.

"Phor Tak," I said, "you hold here within your grasp two secrets which in the hands of a kindly and beneficient power would bring eternal peace to Barsoom."

"Heigh-oo!" he cried. "I do not want peace. I want war. War! War!"

"Very well," I agreed, realizing that my suggestion had not been in line with the mad processes of his crazed brain. "Let us have war then, and what country upon Barsoom is better equipped to wage war than Helium? If you want war, form an alliance with Helium."

"I do not need Helium," he cried. "I do not need to form alliances. I shall make war--I shall make war alone. With the invisible Flying Death I can destroy whole navies, whole cities, entire nations. I shall start with Jahar. Tul Axtar shall be the first to feel the weight of my devastating powers. When the fleet of Jahar has tumbled upon the roofs of Jahar and the walls of Jahar have fallen about the ears of Tul Axtar, then shall I destroy Tjanath. Helium shall know me next. Proud and mighty Helium shall tremble and bow at the feet of Phor Tak. I shall be Jeddak of Jeddaks, ruler of a world." As he spoke his voice rose to a piercing shriek and he trembled in the grip of the frenzy that held him.

He must be destroyed, not alone for the sake of Helium, but for the sake of all Barsoom; this mad mind must be removed if I found that it was impossible to direct or cajole it to my own ends. I determined, however, to omit no sacrifice that might tend to bring about a satisfactory conclusion to this strange adventure. I knew that mad minds were sometimes fickle minds and I hoped that in a moment of insane caprice Phor Tak might reveal to me the secret of the Flying Death and the compound of invisibility. This hope was his temporary reprieve from death; its fulfillment would be his pardon, but I knew that I must work warily--that at the slightest suggestion of duplicity, Phor Tak's suspicions would be aroused and that I should then be the one to be destroyed.

I tossed long upon my sleeping silks and furs that night in troubled thought and planning. I felt that I must possess these secrets; yet how? That they existed within his brain alone, I knew, for he had told me that there were no written formulas, or plans or specifications for either of them. Somehow I must wheedle them out of him and the best way to start was to ingratiate myself with him. To this end I must further his plans insofar as I possibly could.

Just before I fell asleep my thoughts reverted to Sanoma Tora and to the urgent mission that had led me to enter upon what had developed into the strangest adventure of my career. I felt a twinge of self reproach as I suddenly realized that Sanoma Tora had not been uppermost in my mind while I had lain there making plans for the future, but now with recollection of her a plan was suggested whereby I might not only succor her but also advance myself in the good graces of Phor Tak at the same time, and, thus relieved, I fell asleep.

It was late the following morning before I had an opportunity to speak with the old inventor when I immediately broached the subject that was uppermost in my mind. "Phor Tak," I said, "you are handicapped by lack of knowledge of conditions existing in Jahar and the size and location of the fleet. Nur An and I will go to Jahar for you and obtain the information that you must have if your plans are to be successful. In this way, Nur An and I will also be striking a blow at Tul Axtar while we will be in a position to attend to those matters which require our presence in Jahar."

"But how will you get to Jahar?" demanded Phor Tak.

"Could not you let us take a flier?" I asked.

"I have none," replied Phor Tak. "I know nothing about them. I am not interested in them, I could not even build one."

To say that I was both surprised and shocked would be putting it mildly, but if I had previously entertained any doubts that Phor Tak's brain was abnormally developed, it would have vanished with his admission that he knew nothing about fliers, for it seemed to me that there was scarcely a man, woman or child in any of the flying nations of Barsoom but could have constructed some sort of a flier.

"But how without fliers did you expect to transport The Flying Death to the vicinity of the Jaharian fleet? How did you expect to demolish the palace of Tul Axtar, or reduce the city of Jahar to ruins?"

"Now that you and Nur An are here to help me, I can set my slaves to work under you and easily turn out a dozen torpedoes a day. As these are completed they will immediately be launched and eventually they will find their way to Jahar and the fleet. Of that there is no doubt, even if it takes a year they will eventually find their prey."

"If nothing chances to get in their way," I suggested; "but even so what pleasure will you derive from your revenge if you are unable to witness any part of it?"

"Heigh-oo! I have thought of that," replied Phor Tak, "but one may not have everything."

"You may have that," I told him.

"And how?" he demanded.

"By taking your torpedoes aboard a ship and flying to Jahar," I replied.

"No," he exclaimed stubbornly, "I shall do it my own way. What right have you to interfere with my plans?"

"I merely want to help you," I said, attempting to mollify him by a conciliatory tone and attitude.

"And there is another thought," said Nur An, "that suggests that it might be expedient to follow Hadron's plans."

"You are both against me," said Phor Tak.

"By no means," Nur An assured him. "It is our keen desire to aid you that prompts the suggestion."

"Well, what is yours then?" asked the old man.

"Your plan contemplates the destruction of the navies of Tjanath and Helium following the fall of Jahar," exclaimed Nur An. "This, at least in respect to the navy of Helium, you cannot possibly hope to accomplish at so great a distance and without any knowledge of the number of ships to be destroyed, nor will your torpedoes be similarly attracted to them as they are to the ships of Jahar because the ships of these other nations are not protected by the blue paint of Jahar. It will, therefore, be necessary for you to proceed to the vicinity of Tjanath and later to Helium and for your own protection you will use the blue paint of Jahar upon your ship, for you may never be certain unless you are on the ground at the time that you have destroyed all of the navy of Jahar, or all of their disintegrating ray rifles."

"That is true," said Phor Tak thoughtfully.

"And furthermore," continued Nur An, "if you dispatch more than the necessary number of torpedoes, those that remain at large will certainly be attracted by the blue paint of your own ship and you will be destroyed by your own devices."

"You ruin all my plans," screamed Phor Tak. "Why did you think of this?"

"If I had not thought of it you would have been destroyed," Nur An reminded him.

"Well, what am I to do about it? I have no ship. I cannot build a ship."

"We can get you one," I said.

"How?"

The conversation between Nur An and Phor Tak had suggested a plan to me and this I now explained roughly to them. Nur An was enthusiastic over the idea, but Phor Tak was not particularly keen for it. I could not understand the grounds for his objection, nor, as a matter of fact, did they interest me greatly since he finally admitted that he would be compelled to act in accordance with my suggestion.

Immediately adjacent to Phor Tak's laboratory was a well equipped machine shop and here Nur An and I labored for weeks utilizing the services of a dozen slaves until we had succeeded in constructing what I am sure was the most remarkable looking airship that it had ever fallen to my lot to behold. Briefly, it was a cylinder pointed at each end and closely resembled the model of The Flying Death. Within the outer shell was another smaller cylinder; between the walls of these two we placed the buoyancy tanks. The tanks and the sides of the two envelopes were pierced by observation ports along each side of the ship and at the bow and stern. These ports could be completely covered by shutters hinged upon the outside, but operated from within. There were two hatchways in the keel and two above which led to a narrow walkway along the top of the cylinder. In turrets, forward, and aft were mounted two disintegrating ray rifles. Above the controls was a periscope that transmitted an image of all that came within its range to a ground glass plate in front of the pilot. The entire outside of the ship was first painted the ghastly blue that would protect it from the disintegrating ray rifles of Jahar, while over this was spread a coating of the compound of invisibility. The shutters that covered the ports, being similarly coated, the ship could attain practically total invisibility by closing them, the only point remaining visible being the tiny eye of the periscope.

Not possessing sufficient technical knowledge to enable me to build one of the new type motors, I had to content myself with one of the old types of much less efficiency.

At last the work was done. We had a ship that would accommodate four with ease and it was uncanny to realize this fact and yet, at the same time, be unable to see anything but the tiny eye of the periscope when the covers were lowered over the ports, and even the eye of the periscope was invisible unless it was turned in the direction of the observer.

As the work neared completion I had noticed that Phor Tak's manner became more marked by nervousness and irritability. He found fault with everything and on several occasions he almost stopped the work upon the ship.

Now, at last, we were ready to sail. The ship was stocked with ammunition, water and provisions, and at the last minute I installed a destination control compass for which I was afterward to be devoutly thankful.

When I suggested immediate departure, however, Phor Tak demurred, but would give me no reason for his objection. Presently, however, I lost patience and told the old man that we were going anyway whether he liked it or not.

He did not fly into a rage as I had expected, but laughed instead, and there was something in the laugh that seemed more terrible than anger.

"You think I am a fool," he said, "and that I will let you go and carry my secrets to Tul Axtar, but you are mistaken."

"So are you," I snapped. "You are mistaken in thinking that we would betray you and you are also mistaken in thinking that you can prevent our departure."

"Heigh-oo!" he cackled. "I do not need to prevent your departure, but I can prevent your arrival at Jahar or elsewhere. I have not been idle while you worked upon this ship. I have constructed a full size Flying Death. It is attuned to search out this ship. If you depart against my wishes, it will follow and destroy you. Heigh-oo! What do you think of that?"

"I think that you are an old fool," I cried in exasperation. "You have the opportunity to enlist the loyal aid of two honorable warriors and yet you choose to turn them into enemies."

"Enemies who cannot harm me," he reminded me. "I hold your lives in the hollow of my hand. Well have you concealed your thoughts from me, but not quite well enough. I have read enough of them to know that you think me mad and I have also received the impression that you would stop at nothing to prevent me from using my power against Helium. I have no doubt but that you will help me against Jahar, and against Tjanath, too, perhaps, but Helium, the mightiest and proudest empire of Barsoom, is my real goal. Helium shall proclaim me Jeddak of Jeddaks if I have to wreck a world to accomplish my design."

"Then all our work has been for nothing?" I demanded. "We are not going to use the ship we have constructed?"

"We may use it," he said, "but under my terms."

"And what are they?" I asked.

"You may go alone to Jahar, but I shall keep Nur An here as hostage. If you betray me, he dies."

There was no moving him; no amount of argument could alter his determination. I tried to convince him that one man could accomplish little, that, in fact, he might not be able to accomplish anything, but he was adamant--I should go alone or not at all.

XI

"LET THE FIRE BE HOT!"

As I arose that night into the starlit splendor of a Barsoomian night, the white castle of Phor Tak lay a lovely gem below me bathed in the soft light of Thuria. I was alone; Nur An remained behind the hostage of the mad scientist. Because of him I must return to Jhama. Nur An had exacted no promise from me, but he knew that I would return.

Twenty-five hundred haads to the east lay Jahar and Sanoma Tora. Fifteen hundred haads to the southwest were Tjanath and Tavia. I turned the nose of my flier toward the goal of duty, toward the woman I loved, and, with throttle wide, my invisible craft sped toward distant Jahar.

But my thoughts I could not control. Despite my every effort to keep them concentrated upon the purpose of my adventure, they persisted in wandering to a prison tower, to a tousled head of refractory hair, to a rounded shoulder that had once pressed mine. I shook myself to be rid of the vision as I sped through the night, but it constantly returned and in its wake came harrowing thoughts of the fate that might have overtaken Tavia during my absence.

I set my destination control compass upon Jahar, the exact position of which I had obtained from Phor Tak, and thus relieved of the necessity of constantly remaining at the controls, I busied myself about the interior of the ship. I looked to the ammunition of the disintegrating ray rifles and rearranged it to suit my own ideas.

Phor Tak had equipped me with three types of rays; one would disintegrate metal, another would disintegrate wood and the third would disintegrate human flesh. I had also brought along something which Phor Tak had refused me when I had asked him for it. I pressed the pocket pouch in which I had placed it to make sure that I still had the vial, the contents of which I imagined might prove of inestimable value to me.

I raised all the port shutters and adjusted the ventilators, for at best the interior of this strange ship seemed close and stuffy to one who was accustomed to the open deck of the fast scout fliers of Helium. Then I spread my sleeping silks and furs and settled myself down to rest, knowing that when I arrived at Jahar my destination control compass would stop the ship and an alarm would awaken me if I still slept, but sleep would not come. I thought of Sanoma Tora. I visualized her cold and stately beauty, but always her haughty eyes dissolved into the eyes of Tavia, sparkling with the joy of life, soft with the light of friendship.

I was far from Jhama when at last I sprang determinedly from my sleeping silks and furs, and going to the controls, I cut off the destination control compass and with a single, swift turn swung the nose of the flier toward Tjanath.

The die was cast. I felt that I should experience remorse and self loathing, but I experienced neither. I joyed in the thought that I was rushing to the service of a friend and I knew in the most innermost recesses of my heart that of the two, Tavia had more claim upon my friendship than had Sanoma Tora, from whom I had received at best only scant courtesy.

I did not again try to sleep. I did not feel like sleeping; instead I remained at the controls and watched the desolate landscape as it rushed forward to pass beneath me. With the coming of dawn I saw Tjanath directly ahead of me and as I approached the city it was difficult for me to realize that I could do so with utter impunity and that my ship with its closed ports was entirely invisible. Moving slowly now, I circled above the palace of Haj Osis. Those portions of the palace that were topped by flat roofs revealed sleepy guardsmen. At the main hangar a single guardsman watched.

I floated above the east tower; beneath me, cuddled in her sleeping silks and furs, I could picture Tavia. How surprised she would be could she know that I hovered thus close above her.

Dropping lower I circled the tower, coming to a stop finally opposite the windows of the room in which Tavia had been confined. I maneuvered the ship to bring one of the ports opposite the window and close enough to give me a view of the interior of the room. But though I remained there for some time, I could see no one and at last I became convinced that Tavia had been removed to other quarters. I was disappointed for this must necessarily greatly complicate my plans for rescue. I had foreseen but little difficulty in transferring Tavia by night through the tower window to the flier; now I must make my plans all anew. Everything hinged, of course, upon my ability to locate Tavia. To do that it was evident that I must enter the palace. The moment that I quitted the invisibility of my flier, I should be menaced by the greatest danger at every turn, and, clothed as I was in home-made harness fashioned by the hands of the slaves of Phor Tak, I should arouse the active suspicion of the first person who laid eyes upon me.

I must enter the palace and to do it in any degree of safety I must have a disguise.

All my ports were now closed, the periscope being my only eye. I turned it slowly about as I tried to plan some method of procedure that might have within it some tiny seed of success.

As the panorama slowly unfolded itself upon the ground glass before me there appeared the main palace hangar and the single warrior upon watch. Here my periscope came to rest, for here was an entrance to the palace and here a disguise.

Slowly maneuvering my ship in the direction of the hangar, I brought it down upon the roof of that structure. I should have been glad to moor it, but here there were no means at hand. I must depend upon its own weight and hope that no high wind would rise.

Realizing that the instant that I emerged from the interior of the flier I should be entirely visible, I waited, watching through my periscope until the warrior upon the roof just below me turned his back; then I emerged quickly from the ship through one of the upper hatches and dropped to the roof upon the side closest to the warrior. I was about four feet from the edge of the roof and he was standing almost below me, his back toward me. Should he turn he would discover me instantly and would give an alarm before I could be upon him. My only hope of success, therefore, was to silence him before he realized that he was menaced.

I have learned from the experiences of John Carter that first thoughts are often inspirations, while sober afterthought may lead to failure, or so delay action as to nullify all its effect.

Therefore, in this instance, I acted upon inspiration. I did not hesitate. I stepped quickly to the edge of the roof and hurled myself straight at the broad shoulders of the sentry. In my hand was a slim dagger.

The end came quickly. I think the poor fellow never knew what happened to him. Dragging his body to the interior of the hangar I stripped the harness from it, at the same time, though almost mechanically, I noted the ships within the hangar. With the exception of one, a patrol boat, they all bore the personal insignia of the Jed of Tjanath. They were the king's ships--an ornate cruiser heavily armed, two smaller pleasure crafts, a two-man scout flier and a one-man scout flier. They were not much, of course, by comparison with the ships of Helium, but I was quite sure that they were absolutely the best that Tjanath could afford. However, having my own ship, I was not particularly concerned with these other than that I am always interested in ships of all descriptions.

Not far from where I stood was the entrance to a ramp leading down into the palace. Realizing that only through boldness might I succeed, I walked directly to the ramp and entered it. As I rounded the first turn I was appalled to see that the ramp passed directly through a guard room. Upon the floor fully a score of warriors were stretched upon their sleeping silks and furs.

I did not dare to pause; I must keep on. Perhaps I could pass them without arousing their curiosity. I had had but a brief glimpse of the room before I entered it, and in that glimpse I had seen only men apparently wrapped in sleep and an instant later, as I emerged into the room itself, I saw that it contained only those whom I had first seen. No one within it was awake, but I heard voices in an adjoining room. Hurrying quickly across the apartment I entered the ramp upon the opposite side.

I think my heart had stood still as I strode silently across that room among those sleeping men, for had a single one of them awakened he would have inevitably known that I was no fellow member of the guard.

Further down within the palace itself I should be in less danger, for so great is the number of retainers in the palace of a jed that no one may know them all by sight, so that strange and unfamiliar faces are almost as customary as they are upon the avenues of a city.

My plan was to try to reach the tower room in which Tavia had been confined, for I was positive that, from my position in the flier, I could not see the entire interior and it was just possible that Tavia was there.

Owing to the construction of my ship I had been unable to attract her attention without raising a hatch and taking the chance of revealing my presence, which would have, I felt, jeopardized Tavia's chances for escape far too greatly to warrant my doing so.

Perhaps I should have waited until night; perhaps I was over-anxious and in my zeal might be running far greater risks than were necessary. I thought of these things now and perhaps I upbraided myself, but I had gone too far now to retreat. I was properly in for it, whatever might follow.

As I followed the ramp down to different levels I tried to discover some familiar landmark that might lead me to the east tower, and as I emerged into a corridor at one of the levels I saw almost directly in front of me a door which I instantly recognized--it was the door to the office of Yo Seno, the keeper of the keys.

"Good!" I thought. "Fate certainly has led me here."

Crossing to the door I opened it and stepped quickly within the room, closing the door behind me. Yo Seno was sitting at his desk. He was alone. He did not look up. He was one of those arrogant men--a small man with a little authority--who liked to impress his importance upon all inferiors. Therefore, doubtless, it was his way to ignore his visitors for a moment or two. This time he made a mistake. After quietly locking the door behind me I crossed to the door at the opposite end of the room and bolted it, too.

It was then that, doubtless compelled by curiosity, Yo Seno looked up. At first he did not recognize me. "What do you want?" he demanded gruffly.

"You, Yo Seno," I said.

He looked at me steadily for a moment with growing astonishment, then with his eyes wide he leaped to his feet. "You?" he screamed. "By Issus, no! You are dead!"

"I have returned from the grave, Yo Seno. I have come back to haunt you," I said.

"What do you want?" he demanded. "Stand aside! You are under arrest."

"Where is Tavia?" I asked.

"How do I know?" he demanded.

"You are the keeper of the keys, Yo Seno. Who should know better than you where the prisoners are?"

"Well, what if I do know? I shall not tell," he said.

"You shall tell, Yo Seno, or you shall die," I warned him.

He had walked from behind his desk and was standing not far from me when, without warning and with far greater celerity than I gave him credit for possessing, he snatched his long sword from its scabbard and was upon me.

I was forced to jump backward quickly to avoid his first cut, but when he swung the second time my own sword was out and I was on my guard. Yo Seno proved himself no mean antagonist. He was clever with the sword and he knew that he was fighting for his life. I wondered at first why he did not call for help and then I came to the conclusion that it was because there were no warriors in the adjoining room, as there had been upon my previous visit to Yo Seno's quarters. We fought in silence, only the din of metal upon metal reflecting the deadliness of the combat.

I was in a hurry to be done with him and I was pressing him closely when he resorted to a trick which came near to proving my undoing. I had backed him up against his desk and thought that I had him where he could not escape. I could not see his left hand behind him; nor the heavy vase for which it was groping, but an instant later I saw the thing flying straight at my head and I also saw the opening which Yo Seno made in the instant that he cast the missile, for so occupied was he with his aim that he let his point drop. Stooping beneath the vase I sprang into close quarters, driving my sword through the heart of Yo Seno.

As I wiped the blood from my blade upon the hair of my victim I could not repress a feeling of elation that it had been my hand that had cut down the seducer of Phao and in some measure avenged the honor of my friend, Nur An.

Now, however, was no time for meditation. I heard footsteps approaching in the corridor without and hastily seizing the harness of the corpse, I dragged it toward the panel which hid the entrance to the secret corridor that led to the room in the east tower--that familiar corridor where I had passed happy moments alone with Tavia.

With more haste than reverence, I dumped the corpse of Yo Seno into the dark interior and then, closing the panel after me, I groped my way through the darkness toward the tower room, my heart high with the hope that I might find Tavia still there.

As I approached the panel at the tower end of the corridor I could feel my heart beating rapidly--a sensation to which I was unaccustomed and which I could not explain. I was positive that I was in excellent physical condition, and, while it is not at all unusual that surprise or imminent danger causes the heart of some men to palpitate, even though they may be endowed with exceptional courage, yet, for my part, I had never experienced such a sensation and I must admit that I was deeply mystified.

The anticipation of seeing Tavia again soon caused me to forget the unpleasant sensation and as I stopped behind the panel my whole mind was occupied with pleasurable consideration of what I hoped awaited me beyond--the longed for reunion with this best of friends.
