Two hours after leaving my palace at Helium, or about midnight, Kantos Kan, Xodar, and I arrived at Hastor. Carthoris, Tars Tarkas, and Hor Vastus had gone directly to Thark upon another cruiser.

The transports were to get under way immediately and move slowly south. The fleet of battleships would overtake them on the morning of the second day.

At Hastor we found all in readiness, and so perfectly had Kantos Kan planned every detail of the campaign that within ten minutes of our arrival the first of the fleet had soared aloft from its dock, and thereafter, at the rate of one a second, the great ships floated gracefully out into the night to form a long, thin line which stretched for miles toward the south.

It was not until after we had entered the cabin of Kantos Kan that I thought to ask the date, for up to now I was not positive how long I had lain in the pits of Zat Arras. When Kantos Kan told me, I realized with a pang of dismay that I had misreckoned the time while I lay in the utter darkness of my cell. Three hundred and sixty-five days had passed--it was too late to save Dejah Thoris.

The expedition was no longer one of rescue but of revenge. I did not remind Kantos Kan of the terrible fact that ere we could hope to enter the Temple of Issus, the Princess of Helium would be no more. In so far as I knew she might be already dead, for I did not know the exact date on which she first viewed Issus.

What now the value of burdening my friends with my added personal sorrows--they had shared quite enough of them with me in the past. Hereafter I would keep my grief to myself, and so I said nothing to any other of the fact that we were too late. The expedition could yet do much if it could but teach the people of Barsoom the facts of the cruel deception that had been worked upon them for countless ages, and thus save thousands each year from the horrid fate that awaited them at the conclusion of the voluntary pilgrimage.

If it could open to the red men the fair Valley Dor it would have accomplished much, and in the Land of Lost Souls between the Mountains of Otz and the ice barrier were many broad acres that needed no irrigation to bear rich harvests.

Here at the bottom of a dying world was the only naturally productive area upon its surface. Here alone were dews and rains, here alone was an open sea, here was water in plenty; and all this was but the stamping ground of fierce brutes and from its beauteous and fertile expanse the wicked remnants of two once mighty races barred all the other millions of Barsoom. Could I but succeed in once breaking down the barrier of religious superstition which had kept the red races from this El Dorado it would be a fitting memorial to the immortal virtues of my Princess--I should have again served Barsoom and Dejah Thoris' martyrdom would not have been in vain.

On the morning of the second day we raised the great fleet of transports and their consorts at the first flood of dawn, and soon were near enough to exchange signals. I may mention here that radio-aerograms are seldom if ever used in war time, or for the transmission of secret dispatches at any time, for as often as one nation discovers a new cipher, or invents a new instrument for wireless purposes its neighbours bend every effort until they are able to intercept and translate the messages. For so long a time has this gone on that practically every possibility of wireless communication has been exhausted and no nation dares transmit dispatches of importance in this way.

Tars Tarkas reported all well with the transports. The battleships passed through to take an advanced position, and the combined fleets moved slowly over the ice cap, hugging the surface closely to prevent detection by the therns whose land we were approaching.

Far in advance of all a thin line of one-man air scouts protected us from surprise, and on either side they flanked us, while a smaller number brought up the rear some twenty miles behind the transports. In this formation we had progressed toward the entrance to Omean for several hours when one of our scouts returned from the front to report that the cone-like summit of the entrance was in sight. At almost the same instant another scout from the left flank came racing toward the flagship.

His very speed bespoke the importance of his information. Kantos Kan and I awaited him upon the little forward deck which corresponds with the bridge of earthly battleships. Scarcely had his tiny flier come to rest upon the broad landing-deck of the flagship ere he was bounding up the stairway to the deck where we stood.

"A great fleet of battleships south-south-east, my Prince," he cried. "There must be several thousands and they are bearing down directly upon us."

"The thern spies were not in the palace of John Carter for nothing," said Kantos Kan to me. "Your orders, Prince."

"Dispatch ten battleships to guard the entrance to Omean, with orders to let no hostile enter or leave the shaft. That will bottle up the great fleet of the First Born.

"Form the balance of the battleships into a great V with the apex pointing directly south-south-east. Order the transports, surrounded by their convoys, to follow closely in the wake of the battleships until the point of the V has entered the enemies' line, then the V must open outward at the apex, the battleships of each leg engage the enemy fiercely and drive him back to form a lane through his line into which the transports with their convoys must race at top speed that they may gain a position above the temples and gardens of the therns.

"Here let them land and teach the Holy Therns such a lesson in ferocious warfare as they will not forget for countless ages. It had not been my intention to be distracted from the main issue of the campaign, but we must settle this attack with the therns once and for all, or there will be no peace for us while our fleet remains near Dor, and our chances of ever returning to the outer world will be greatly minimized."

Kantos Kan saluted and turned to deliver my instructions to his waiting aides. In an incredibly short space of time the formation of the battleships changed in accordance with my commands, the ten that were to guard the way to Omean were speeding toward their destination, and the troopships and convoys were closing up in preparation for the spurt through the lane.

The order of full speed ahead was given, the fleet sprang through the air like coursing greyhounds, and in another moment the ships of the enemy were in full view. They formed a ragged line as far as the eye could reach in either direction and about three ships deep. So sudden was our onslaught that they had no time to prepare for it. It was as unexpected as lightning from a clear sky.

Every phase of my plan worked splendidly. Our huge ships mowed their way entirely through the line of thern battlecraft; then the V opened up and a broad lane appeared through which the transports leaped toward the temples of the therns which could now be plainly seen glistening in the sunlight. By the time the therns had rallied from the attack a hundred thousand green warriors were already pouring through their courts and gardens, while a hundred and fifty thousand others leaned from low swinging transports to direct their almost uncanny marksmanship upon the thern soldiery that manned the ramparts, or attempted to defend the temples.

Now the two great fleets closed in a titanic struggle far above the fiendish din of battle in the gorgeous gardens of the therns. Slowly the two lines of Helium's battleships joined their ends, and then commenced the circling within the line of the enemy which is so marked a characteristic of Barsoomian naval warfare.

Around and around in each other's tracks moved the ships under Kantos Kan, until at length they formed nearly a perfect circle. By this time they were moving at high speed so that they presented a difficult target for the enemy. Broadside after broadside they delivered as each vessel came in line with the ships of the therns. The latter attempted to rush in and break up the formation, but it was like stopping a buzz saw with the bare hand.

From my position on the deck beside Kantos Kan I saw ship after ship of the enemy take the awful, sickening dive which proclaims its total destruction. Slowly we manoeuvered our circle of death until we hung above the gardens where our green warriors were engaged. The order was passed down for them to embark. Then they rose slowly to a position within the centre of the circle.

In the meantime the therns' fire had practically ceased. They had had enough of us and were only too glad to let us go on our way in peace. But our escape was not to be encompassed with such ease, for scarcely had we gotten under way once more in the direction of the entrance to Omean than we saw far to the north a great black line topping the horizon. It could be nothing other than a fleet of war.

Whose or whither bound, we could not even conjecture. When they had come close enough to make us out at all, Kantos Kan's operator received a radio-aerogram, which he immediately handed to my companion. He read the thing and handed it to me.

"Kantos Kan:" it read. "Surrender, in the name of the Jeddak of Helium, for you cannot escape," and it was signed, "Zat Arras."

The therns must have caught and translated the message almost as soon as did we, for they immediately renewed hostilities when they realized that we were soon to be set upon by other enemies.

Before Zat Arras had approached near enough to fire a shot we were again hotly engaged with the thern fleet, and as soon as he drew near he too commenced to pour a terrific fusillade of heavy shot into us. Ship after ship reeled and staggered into uselessness beneath the pitiless fire that we were undergoing.

The thing could not last much longer. I ordered the transports to descend again into the gardens of the therns.

"Wreak your vengeance to the utmost," was my message to the green allies, "for by night there will be none left to avenge your wrongs."

Presently I saw the ten battleships that had been ordered to hold the shaft of Omean. They were returning at full speed, firing their stern batteries almost continuously. There could be but one explanation. They were being pursued by another hostile fleet. Well, the situation could be no worse. The expedition already was doomed. No man that had embarked upon it would return across that dreary ice cap. How I wished that I might face Zat Arras with my longsword for just an instant before I died! It was he who had caused our failure.

As I watched the oncoming ten I saw their pursuers race swiftly into sight. It was another great fleet; for a moment I could not believe my eyes, but finally I was forced to admit that the most fatal calamity had overtaken the expedition, for the fleet I saw was none other than the fleet of the First Born, that should have been safely bottled up in Omean. What a series of misfortunes and disasters! What awful fate hovered over me, that I should have been so terribly thwarted at every angle of my search for my lost love! Could it be possible that the curse of Issus was upon me! That there was, indeed, some malign divinity in that hideous carcass! I would not believe it, and, throwing back my shoulders, I ran to the deck below to join my men in repelling boarders from one of the thern craft that had grappled us broadside. In the wild lust of hand-to-hand combat my old dauntless hopefulness returned. And as thern after thern went down beneath my blade, I could almost feel that we should win success in the end, even from apparent failure.

My presence among the men so greatly inspirited them that they fell upon the luckless whites with such terrible ferocity that within a few moments we had turned the tables upon them and a second later as we swarmed their own decks I had the satisfaction of seeing their commander take the long leap from the bows of his vessel in token of surrender and defeat.

Then I joined Kantos Kan. He had been watching what had taken place on the deck below, and it seemed to have given him a new thought. Immediately he passed an order to one of his officers, and presently the colours of the Prince of Helium broke from every point of the flagship. A great cheer arose from the men of our own ship, a cheer that was taken up by every other vessel of our expedition as they in turn broke my colours from their upper works.

Then Kantos Kan sprang his coup. A signal legible to every sailor of all the fleets engaged in that fierce struggle was strung aloft upon the flagship.

"Men of Helium for the Prince of Helium against all his enemies," it read. Presently my colours broke from one of Zat Arras' ships. Then from another and another. On some we could see fierce battles waging between the Zodangan soldiery and the Heliumetic crews, but eventually the colours of the Prince of Helium floated above every ship that had followed Zat Arras upon our trail--only his flagship flew them not.

Zat Arras had brought five thousand ships. The sky was black with the three enormous fleets. It was Helium against the field now, and the fight had settled to countless individual duels. There could be little or no manoeuvering of fleets in that crowded, fire-split sky.

Zat Arras' flagship was close to my own. I could see the thin features of the man from where I stood. His Zodangan crew was pouring broadside after broadside into us and we were returning their fire with equal ferocity. Closer and closer came the two vessels until but a few yards intervened. Grapplers and boarders lined the contiguous rails of each. We were preparing for the death struggle with our hated enemy.

There was but a yard between the two mighty ships as the first grappling irons were hurled. I rushed to the deck to be with my men as they boarded. Just as the vessels came together with a slight shock, I forced my way through the lines and was the first to spring to the deck of Zat Arras' ship. After me poured a yelling, cheering, cursing throng of Helium's best fighting-men. Nothing could withstand them in the fever of battle lust which enthralled them.

Down went the Zodangans before that surging tide of war, and as my men cleared the lower decks I sprang to the forward deck where stood Zat Arras.

"You are my prisoner, Zat Arras," I cried. "Yield and you shall have quarter."

For a moment I could not tell whether he contemplated acceding to my demand or facing me with drawn sword. For an instant he stood hesitating, and then throwing down his arms he turned and rushed to the opposite side of the deck. Before I could overtake him he had sprung to the rail and hurled himself headforemost into the awful depths below.

And thus came Zat Arras, Jed of Zodanga, to his end.

On and on went that strange battle. The therns and blacks had not combined against us. Wherever thern ship met ship of the First Born was a battle royal, and in this I thought I saw our salvation. Wherever messages could be passed between us that could not be intercepted by our enemies I passed the word that all our vessels were to withdraw from the fight as rapidly as possible, taking a position to the west and south of the combatants. I also sent an air scout to the fighting green men in the gardens below to re-embark, and to the transports to join us.

My commanders were further instructed than when engaged with an enemy to draw him as rapidly as possible toward a ship of his hereditary foeman, and by careful manoeuvring to force the two to engage, thus leaving him-self free to withdraw. This stratagem worked to perfection, and just before the sun went down I had the satisfaction of seeing all that was left of my once mighty fleet gathered nearly twenty miles southwest of the still terrific battle between the blacks and whites.

I now transferred Xodar to another battleship and sent him with all the transports and five thousand battleships directly overhead to the Temple of Issus. Carthoris and I, with Kantos Kan, took the remaining ships and headed for the entrance to Omean.

Our plan now was to attempt to make a combined assault upon Issus at dawn of the following day. Tars Tarkas with his green warriors and Hor Vastus with the red men, guided by Xodar, were to land within the garden of Issus or the surrounding plains; while Carthoris, Kantos Kan, and I were to lead our smaller force from the sea of Omean through the pits beneath the temple, which Carthoris knew so well.

I now learned for the first time the cause of my ten ships' retreat from the mouth of the shaft. It seemed that when they had come upon the shaft the navy of the First Born were already issuing from its mouth. Fully twenty vessels had emerged, and though they gave battle immediately in an effort to stem the tide that rolled from the black pit, the odds against them were too great and they were forced to flee.

With great caution we approached the shaft, under cover of darkness. At a distance of several miles I caused the fleet to be halted, and from there Carthoris went ahead alone upon a one-man flier to reconnoitre. In perhaps half an hour he returned to report that there was no sign of a patrol boat or of the enemy in any form, and so we moved swiftly and noiselessly forward once more toward Omean.

At the mouth of the shaft we stopped again for a moment for all the vessels to reach their previously appointed stations, then with the flagship I dropped quickly into the black depths, while one by one the other vessels followed me in quick succession.

We had decided to stake all on the chance that we would be able to reach the temple by the subterranean way and so we left no guard of vessels at the shaft's mouth. Nor would it have profited us any to have done so, for we did not have sufficient force all told to have withstood the vast navy of the First Born had they returned to engage us.

For the safety of our entrance upon Omean we depended largely upon the very boldness of it, believing that it would be some little time before the First Born on guard there would realize that it was an enemy and not their own returning fleet that was entering the vault of the buried sea.

And such proved to be the case. In fact, four hundred of my fleet of five hundred rested safely upon the bosom of Omean before the first shot was fired. The battle was short and hot, but there could have been but one outcome, for the First Born in the carelessness of fancied security had left but a handful of ancient and obsolete hulks to guard their mighty harbour.

It was at Carthoris' suggestion that we landed our prisoners under guard upon a couple of the larger islands, and then towed the ships of the First Born to the shaft, where we managed to wedge a number of them securely in the interior of the great well. Then we turned on the buoyance rays in the balance of them and let them rise by themselves to further block the passage to Omean as they came into contact with the vessels already lodged there.

We now felt that it would be some time at least before the returning First Born could reach the surface of Omean, and that we would have ample opportunity to make for the subterranean passages which lead to Issus. One of the first steps I took was to hasten personally with a good-sized force to the island of the submarine, which I took without resistance on the part of the small guard there.

I found the submarine in its pool, and at once placed a strong guard upon it and the island, where I remained to wait the coming of Carthoris and the others.

Among the prisoners was Yersted, commander of the submarine. He recognized me from the three trips that I had taken with him during my captivity among the First Born.

"How does it seem," I asked him, "to have the tables turned? To be prisoner of your erstwhile captive?"

He smiled, a very grim smile pregnant with hidden meaning.

"It will not be for long, John Carter," he replied. "We have been expecting you and we are prepared."

"So it would appear," I answered, "for you were all ready to become my prisoners with scarce a blow struck on either side."

"The fleet must have missed you," he said, "but it will return to Omean, and then that will be a very different matter--for John Carter."

"I do not know that the fleet has missed me as yet," I said, but of course he did not grasp my meaning, and only looked puzzled.

"Many prisoners travel to Issus in your grim craft, Yersted?" I asked.

"Very many," he assented.

"Might you remember one whom men called Dejah Thoris?"

"Well, indeed, for her great beauty, and then, too, for the fact that she was wife to the first mortal that ever escaped from Issus through all the countless ages of her godhood. And the way that Issus remembers her best as the wife of one and the mother of another who raised their hands against the Goddess of Life Eternal."

I shuddered for fear of the cowardly revenge that I knew Issus might have taken upon the innocent Dejah Thoris for the sacrilege of her son and her husband.

"And where is Dejah Thoris now?" I asked, knowing that he would say the words I most dreaded, but yet I loved her so that I could not refrain from hearing even the worst about her fate so that it fell from the lips of one who had seen her but recently. It was to me as though it brought her closer to me.

"Yesterday the monthly rites of Issus were held," replied Yersted, "and I saw her then sitting in her accustomed place at the foot of Issus."

"What," I cried, "she is not dead, then?"

"Why, no," replied the black, "it has been no year since she gazed upon the divine glory of the radiant face of--"

"No year?" I interrupted.

"Why, no," insisted Yersted. "It cannot have been upward of three hundred and seventy or eighty days."

A great light burst upon me. How stupid I had been! I could scarcely retain an outward exhibition of my great joy. Why had I forgotten the great difference in the length of Martian and Earthly years! The ten Earth years I had spent upon Barsoom had encompassed but five years and ninety-six days of Martian time, whose days are forty-one minutes longer than ours, and whose years number six hundred and eighty-seven days.

I am in time! I am in time! The words surged through my brain again and again, until at last I must have voiced them audibly, for Yersted shook his head.

"In time to save your Princess?" he asked, and then without waiting for my reply, "No, John Carter, Issus will not give up her own. She knows that you are coming, and ere ever a vandal foot is set within the precincts of the Temple of Issus, if such a calamity should befall, Dejah Thoris will be put away for ever from the last faint hope of rescue."

"You mean that she will be killed merely to thwart me?" I asked.

"Not that, other than as a last resort," he replied. "Hast ever heard of the Temple of the Sun? It is there that they will put her. It lies far within the inner court of the Temple of Issus, a little temple that raises a thin spire far above the spires and minarets of the great temple that surrounds it. Beneath it, in the ground, there lies the main body of the temple consisting in six hundred and eighty-seven circular chambers, one below another. To each chamber a single corridor leads through solid rock from the pits of Issus.

"As the entire Temple of the Sun revolves once with each revolution of Barsoom about the sun, but once each year does the entrance to each separate chamber come opposite the mouth of the corridor which forms its only link to the world without.

"Here Issus puts those who displease her, but whom she does not care to execute forthwith. Or to punish a noble of the First Born she may cause him to be placed within a chamber of the Temple of the Sun for a year. Ofttimes she imprisons an executioner with the condemned, that death may come in a certain horrible form upon a given day, or again but enough food is deposited in the chamber to sustain life but the number of days that Issus has allotted for mental anguish.

"Thus will Dejah Thoris die, and her fate will be sealed by the first alien foot that crosses the threshold of Issus."

So I was to be thwarted in the end, although I had performed the miraculous and come within a few short moments of my divine Princess, yet was I as far from her as when I stood upon the banks of the Hudson forty-eight million miles away.

CHAPTER XXI

THROUGH FLOOD AND FLAME

Yersted's information convinced me that there was no time to be lost. I must reach the Temple of Issus secretly before the forces under Tars Tarkas assaulted at dawn. Once within its hated walls I was positive that I could overcome the guards of Issus and bear away my Princess, for at my back I would have a force ample for the occasion.

No sooner had Carthoris and the others joined me than we commenced the transportation of our men through the submerged passage to the mouth of the gangways which lead from the submarine pool at the temple end of the watery tunnel to the pits of Issus.

Many trips were required, but at last all stood safely together again at the beginning of the end of our quest. Five thousand strong we were, all seasoned fighting-men of the most warlike race of the red men of Barsoom.

As Carthoris alone knew the hidden ways of the tunnels we could not divide the party and attack the temple at several points at once as would have been most desirable, and so it was decided that he lead us all as quickly as possible to a point near the temple's centre.

As we were about to leave the pool and enter the corridor, an officer called my attention to the waters upon which the submarine floated. At first they seemed to be merely agitated as from the movement of some great body beneath the surface, and I at once conjectured that another submarine was rising to the surface in pursuit of us; but presently it became apparent that the level of the waters was rising, not with extreme rapidity, but very surely, and that soon they would overflow the sides of the pool and submerge the floor of the chamber.

For a moment I did not fully grasp the terrible import of the slowly rising water. It was Carthoris who realized the full meaning of the thing--its cause and the reason for it.

"Haste!" he cried. "If we delay, we all are lost. The pumps of Omean have been stopped. They would drown us like rats in a trap. We must reach the upper levels of the pits in advance of the flood or we shall never reach them. Come."

"Lead the way, Carthoris," I cried. "We will follow."

At my command, the youth leaped into one of the corridors, and in column of twos the soldiers followed him in good order, each company entering the corridor only at the command of its dwar, or captain.

Before the last company filed from the chamber the water was ankle deep, and that the men were nervous was quite evident. Entirely unaccustomed to water except in quantities sufficient for drinking and bathing purposes the red Martians instinctively shrank from it in such formidable depths and menacing activity. That they were undaunted while it swirled and eddied about their ankles, spoke well for their bravery and their discipline.

I was the last to leave the chamber of the submarine, and as I followed the rear of the column toward the corridor, I moved through water to my knees. The corridor, too, was flooded to the same depth, for its floor was on a level with the floor of the chamber from which it led, nor was there any perceptible rise for many yards.

The march of the troops through the corridor was as rapid as was consistent with the number of men that moved through so narrow a passage, but it was not ample to permit us to gain appreciably on the pursuing tide. As the level of the passage rose, so, too, did the waters rise until it soon became apparent to me, who brought up the rear, that they were gaining rapidly upon us. I could understand the reason for this, as with the narrowing expanse of Omean as the waters rose toward the apex of its dome, the rapidity of its rise would increase in inverse ratio to the ever-lessening space to be filled.

Long ere the last of the column could hope to reach the upper pits which lay above the danger point I was convinced that the waters would surge after us in overwhelming volume, and that fully half the expedition would be snuffed out.

As I cast about for some means of saving as many as possible of the doomed men, I saw a diverging corridor which seemed to rise at a steep angle at my right. The waters were now swirling about my waist. The men directly before me were quickly becoming panic-stricken. Something must be done at once or they would rush forward upon their fellows in a mad stampede that would result in trampling down hundreds beneath the flood and eventually clogging the passage beyond any hope of retreat for those in advance.

Raising my voice to its utmost, I shouted my command to the dwars ahead of me.

"Call back the last twenty-five utans," I shouted. "Here seems a way of escape. Turn back and follow me."

My orders were obeyed by nearer thirty utans, so that some three thousand men came about and hastened into the teeth of the flood to reach the corridor up which I directed them.

As the first dwar passed in with his utan I cautioned him to listen closely for my commands, and under no circumstances to venture into the open, or leave the pits for the temple proper until I should have come up with him, "or you know that I died before I could reach you."

The officer saluted and left me. The men filed rapidly past me and entered the diverging corridor which I hoped would lead to safety. The water rose breast high. Men stumbled, floundered, and went down. Many I grasped and set upon their feet again, but alone the work was greater than I could cope with. Soldiers were being swept beneath the boiling torrent, never to rise. At length the dwar of the 10th utan took a stand beside me. He was a valorous soldier, Gur Tus by name, and together we kept the now thoroughly frightened troops in the semblance of order and rescued many that would have drowned otherwise.

Djor Kantos, son of Kantos Kan, and a padwar of the fifth utan joined us when his utan reached the opening through which the men were fleeing. Thereafter not a man was lost of all the hundreds that remained to pass from the main corridor to the branch.

As the last utan was filing past us the waters had risen until they surged about our necks, but we clasped hands and stood our ground until the last man had passed to the comparative safety of the new passageway. Here we found an immediate and steep ascent, so that within a hundred yards we had reached a point above the waters.

For a few minutes we continued rapidly up the steep grade, which I hoped would soon bring us quickly to the upper pits that let into the Temple of Issus. But I was to meet with a cruel disappointment.

Suddenly I heard a cry of "fire" far ahead, followed almost at once by cries of terror and the loud commands of dwars and padwars who were evidently attempting to direct their men away from some grave danger. At last the report came back to us. "They have fired the pits ahead." "We are hemmed in by flames in front and flood behind." "Help, John Carter; we are suffocating," and then there swept back upon us at the rear a wave of dense smoke that sent us, stumbling and blinded, into a choking retreat.

There was naught to do other than seek a new avenue of escape. The fire and smoke were to be feared a thousand times over the water, and so I seized upon the first gallery which led out of and up from the suffocating smoke that was engulfing us.

Again I stood to one side while the soldiers hastened through on the new way. Some two thousand must have passed at a rapid run, when the stream ceased, but I was not sure that all had been rescued who had not passed the point of origin of the flames, and so to assure myself that no poor devil was left behind to die a horrible death, unsuccoured, I ran quickly up the gallery in the direction of the flames which I could now see burning with a dull glow far ahead.

It was hot and stifling work, but at last I reached a point where the fire lit up the corridor sufficiently for me to see that no soldier of Helium lay between me and the conflagration--what was in it or upon the far side I could not know, nor could any man have passed through that seething hell of chemicals and lived to learn.

Having satisfied my sense of duty, I turned and ran rapidly back to the corridor through which my men had passed. To my horror, however, I found that my retreat in this direction had been blocked--across the mouth of the corridor stood a massive steel grating that had evidently been lowered from its resting-place above for the purpose of effectually cutting off my escape.

That our principal movements were known to the First Born I could not have doubted, in view of the attack of the fleet upon us the day before, nor could the stopping of the pumps of Omean at the psychological moment have been due to chance, nor the starting of a chemical combustion within the one corridor through which we were advancing upon the Temple of Issus been due to aught than well-calculated design.

And now the dropping of the steel gate to pen me effectually between fire and flood seemed to indicate that invisible eyes were upon us at every moment. What chance had I, then, to rescue Dejah Thoris were I to be compelled to fight foes who never showed themselves. A thousand times I berated myself for being drawn into such a trap as I might have known these pits easily could be. Now I saw that it would have been much better to have kept our force intact and made a concerted attack upon the temple from the valley side, trusting to chance and our great fighting ability to have overwhelmed the First Born and compelled the safe delivery of Dejah Thoris to me.

The smoke from the fire was forcing me further and further back down the corridor toward the waters which I could hear surging through the darkness. With my men had gone the last torch, nor was this corridor lighted by the radiance of phosphorescent rock as were those of the lower levels. It was this fact that assured me that I was not far from the upper pits which lie directly beneath the temple.

Finally I felt the lapping waters about my feet. The smoke was thick behind me. My suffering was intense. There seemed but one thing to do, and that to choose the easier death which confronted me, and so I moved on down the corridor until the cold waters of Omean closed about me, and I swam on through utter blackness toward--what?

The instinct of self-preservation is strong even when one, unafraid and in the possession of his highest reasoning faculties, knows that death--positive and unalterable--lies just ahead. And so I swam slowly on, waiting for my head to touch the top of the corridor, which would mean that I had reached the limit of my flight and the point where I must sink for ever to an unmarked grave.

But to my surprise I ran against a blank wall before I reached a point where the waters came to the roof of the corridor. Could I be mistaken? I felt around. No, I had come to the main corridor, and still there was a breathing space between the surface of the water and the rocky ceiling above. And then I turned up the main corridor in the direction that Carthoris and the head of the column had passed a half-hour before. On and on I swam, my heart growing lighter at every stroke, for I knew that I was approaching closer and closer to the point where there would be no chance that the waters ahead could be deeper than they were about me. I was positive that I must soon feel the solid floor beneath my feet again and that once more my chance would come to reach the Temple of Issus and the side of the fair prisoner who languished there.

But even as hope was at its highest I felt the sudden shock of contact as my head struck the rocks above. The worst, then, had come to me. I had reached one of those rare places where a Martian tunnel dips suddenly to a lower level. Somewhere beyond I knew that it rose again, but of what value was that to me, since I did not know how great the distance that it maintained a level entirely beneath the surface of the water!

There was but a single forlorn hope, and I took it. Filling my lungs with air, I dived beneath the surface and swam through the inky, icy blackness on and on along the submerged gallery. Time and time again I rose with upstretched hand, only to feel the disappointing rocks close above me.

Not for much longer would my lungs withstand the strain upon them. I felt that I must soon succumb, nor was there any retreating now that I had gone this far. I knew positively that I could never endure to retrace my path now to the point from which I had felt the waters close above my head. Death stared me in the face, nor ever can I recall a time that I so distinctly felt the icy breath from his dead lips upon my brow.

One more frantic effort I made with my fast ebbing strength. Weakly I rose for the last time--my tortured lungs gasped for the breath that would fill them with a strange and numbing element, but instead I felt the revivifying breath of life-giving air surge through my starving nostrils into my dying lungs. I was saved.

A few more strokes brought me to a point where my feet touched the floor, and soon thereafter I was above the water level entirely, and racing like mad along the corridor searching for the first doorway that would lead me to Issus. If I could not have Dejah Thoris again I was at least determined to avenge her death, nor would any life satisfy me other than that of the fiend incarnate who was the cause of such immeasurable suffering upon Barsoom.

Sooner than I had expected I came to what appeared to me to be a sudden exit into the temple above. It was at the right side of the corridor, which ran on, probably, to other entrances to the pile above.

To me one point was as good as another. What knew I where any of them led! And so without waiting to be again discovered and thwarted, I ran quickly up the short, steep incline and pushed open the doorway at its end.

The portal swung slowly in, and before it could be slammed against me I sprang into the chamber beyond. Although not yet dawn, the room was brilliantly lighted. Its sole occupant lay prone upon a low couch at the further side, apparently in sleep. From the hangings and sumptuous furniture of the room I judged it to be a living-room of some priestess, possibly of Issus herself.

At the thought the blood tingled through my veins. What, indeed, if fortune had been kind enough to place the hideous creature alone and unguarded in my hands. With her as hostage I could force acquiescence to my every demand. Cautiously I approached the recumbent figure, on noiseless feet. Closer and closer I came to it, but I had crossed but little more than half the chamber when the figure stirred, and, as I sprang, rose and faced me.

At first an expression of terror overspread the features of the woman who confronted me--then startled incredulity--hope--thanksgiving.

My heart pounded within my breast as I advanced toward her--tears came to my eyes--and the words that would have poured forth in a perfect torrent choked in my throat as I opened my arms and took into them once more the woman I loved--Dejah Thoris, Princess of Helium.
