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.

"John Carter, John Carter," she sobbed, with her dear head upon my shoulder; "even now I can scarce believe the witness of my own eyes. When the girl, Thuvia, told me that you had returned to Barsoom, I listened, but I could not understand, for it seemed that such happiness would be impossible for one who had suffered so in silent loneliness for all these long years. At last, when I realized that it was truth, and then came to know the awful place in which I was held prisoner, I learned to doubt that even you could reach me here.

"As the days passed, and moon after moon went by without bringing even the faintest rumour of you, I resigned myself to my fate. And now that you have come, scarce can I believe it. For an hour I have heard the sounds of conflict within the palace. I knew not what they meant, but I have hoped against hope that it might be the men of Helium headed by my Prince.

"And tell me, what of Carthoris, our son?"

"He was with me less than an hour since, Dejah Thoris," I replied. "It must have been he whose men you have heard battling within the precincts of the temple.

"Where is Issus?" I asked suddenly.

Dejah Thoris shrugged her shoulders.

"She sent me under guard to this room just before the fighting began within the temple halls. She said that she would send for me later. She seemed very angry and somewhat fearful. Never have I seen her act in so uncertain and almost terrified a manner. Now I know that it must have been because she had learned that John Carter, Prince of Helium, was approaching to demand an accounting of her for the imprisonment of his Princess."

The sounds of conflict, the clash of arms, the shouting and the hurrying of many feet came to us from various parts of the temple. I knew that I was needed there, but I dared not leave Dejah Thoris, nor dared I take her with me into the turmoil and danger of battle.

At last I bethought me of the pits from which I had just emerged. Why not secrete her there until I could return and fetch her away in safety and for ever from this awful place. I explained my plan to her.

For a moment she clung more closely to me.

"I cannot bear to be parted from you now, even for a moment, John Carter," she said. "I shudder at the thought of being alone again where that terrible creature might discover me. You do not know her. None can imagine her ferocious cruelty who has not witnessed her daily acts for over half a year. It has taken me nearly all this time to realize even the things that I have seen with my own eyes."

"I shall not leave you, then, my Princess," I replied.

She was silent for a moment, then she drew my face to hers and kissed me.

"Go, John Carter," she said. "Our son is there, and the soldiers of Helium, fighting for the Princess of Helium. Where they are you should be. I must not think of myself now, but of them and of my husband's duty. I may not stand in the way of that. Hide me in the pits, and go."

I led her to the door through which I had entered the chamber from below. There I pressed her dear form to me, and then, though it tore my heart to do it, and filled me only with the blackest shadows of terrible foreboding, I guided her across the threshold, kissed her once again, and closed the door upon her.

Without hesitating longer, I hurried from the chamber in the direction of the greatest tumult. Scarce half a dozen chambers had I traversed before I came upon the theatre of a fierce struggle. The blacks were massed at the entrance to a great chamber where they were attempting to block the further progress of a body of red men toward the inner sacred precincts of the temple.

Coming from within as I did, I found myself behind the blacks, and, without waiting to even calculate their numbers or the foolhardiness of my venture, I charged swiftly across the chamber and fell upon them from the rear with my keen long-sword.

As I struck the first blow I cried aloud, "For Helium!" And then I rained cut after cut upon the surprised warriors, while the reds without took heart at the sound of my voice, and with shouts of "John Carter! John Carter!" redoubled their efforts so effectually that before the blacks could recover from their temporary demoralization their ranks were broken and the red men had burst into the chamber.

The fight within that room, had it had but a competent chronicler, would go down in the annals of Barsoom as a historic memorial to the grim ferocity of her warlike people. Five hundred men fought there that day, the black men against the red. No man asked quarter or gave it. As though by common assent they fought, as though to determine once and for all their right to live, in accordance with the law of the survival of the fittest.

I think we all knew that upon the outcome of this battle would hinge for ever the relative positions of these two races upon Barsoom. It was a battle between the old and the new, but not for once did I question the outcome of it. With Carthoris at my side I fought for the red men of Barsoom and for their total emancipation from the throttling bondage of a hideous superstition.

Back and forth across the room we surged, until the floor was ankle deep in blood, and dead men lay so thickly there that half the time we stood upon their bodies as we fought. As we swung toward the great windows which overlooked the gardens of Issus a sight met my gaze which sent a wave of exultation over me.

"Look!" I cried. "Men of the First Born, look!"

For an instant the fighting ceased, and with one accord every eye turned in the direction I had indicated, and the sight they saw was one no man of the First Born had ever imagined could be.

Across the gardens, from side to side, stood a wavering line of black warriors, while beyond them and forcing them ever back was a great horde of green warriors astride their mighty thoats. And as we watched, one, fiercer and more grimly terrible than his fellows, rode forward from the rear, and as he came he shouted some fierce command to his terrible legion.

It was Tars Tarkas, Jeddak of Thark, and as he couched his great forty-foot metal-shod lance we saw his warriors do likewise. Then it was that we interpreted his command. Twenty yards now separated the green men from the black line. Another word from the great Thark, and with a wild and terrifying battle-cry the green warriors charged. For a moment the black line held, but only for a moment-then the fearsome beasts that bore equally terrible riders passed completely through it.

After them came utan upon utan of red men. The green horde broke to surround the temple. The red men charged for the interior, and then we turned to continue our interrupted battle; but our foes had vanished.
