A huge black entered the arena with the young women. Carefully he inspected them, felt of their limbs and poked them in the ribs. Presently he selected one of their number whom he led before the throne of Issus. He addressed some words to the goddess which I could not hear. Issus nodded her head. The black raised his hands above his head in token of salute, grasped the girl by the wrist, and dragged her from the arena through a small doorway below the throne.

"Issus will dine well to-night," said a prisoner beside me.

"What do you mean?" I asked.

"That was her dinner that old Thabis is taking to the kitchens. Didst not note how carefully he selected the plumpest and tenderest of the lot?"

I growled out my curses on the monster sitting opposite us on the gorgeous throne.

"Fume not," admonished my companion; "you will see far worse than that if you live even a month among the First Born."

I turned again in time to see the gate of a nearby cage thrown open and three monstrous white apes spring into the arena. The girls shrank in a frightened group in the centre of the enclosure.

One was on her knees with imploring hands outstretched toward Issus; but the hideous deity only leaned further forward in keener anticipation of the entertainment to come. At length the apes spied the huddled knot of terror-stricken maidens and with demoniacal shrieks of bestial frenzy, charged upon them.

A wave of mad fury surged over me. The cruel cowardliness of the power-drunk creature whose malignant mind conceived such frightful forms of torture stirred to their uttermost depths my resentment and my manhood. The blood-red haze that presaged death to my foes swam before my eyes.

The guard lolled before the unbarred gate of the cage which confined me. What need of bars, indeed, to keep those poor victims from rushing into the arena which the edict of the gods had appointed as their death place!

A single blow sent the black unconscious to the ground. Snatching up his long-sword, I sprang into the arena. The apes were almost upon the maidens, but a couple of mighty bounds were all my earthly muscles required to carry me to the centre of the sand-strewn floor.

For an instant silence reigned in the great amphitheatre, then a wild shout arose from the cages of the doomed. My long-sword circled whirring through the air, and a great ape sprawled, headless, at the feet of the fainting girls.

The other apes turned now upon me, and as I stood facing them a sullen roar from the audience answered the wild cheers from the cages. From the tail of my eye I saw a score of guards rushing across the glistening sand toward me. Then a figure broke from one of the cages behind them. It was the youth whose personality so fascinated me.

He paused a moment before the cages, with upraised sword.

"Come, men of the outer world!" he shouted. "Let us make our deaths worth while, and at the back of this unknown warrior turn this day's Tribute to Issus into an orgy of revenge that will echo through the ages and cause black skins to blanch at each repetition of the rites of Issus. Come! The racks without your cages are filled with blades."

Without waiting to note the outcome of his plea, he turned and bounded toward me. From every cage that harboured red men a thunderous shout went up in answer to his exhortation. The inner guards went down beneath howling mobs, and the cages vomited forth their inmates hot with the lust to kill.

The racks that stood without were stripped of the swords with which the prisoners were to have been armed to enter their allotted combats, and a swarm of determined warriors sped to our support.

The great apes, towering in all their fifteen feet of height, had gone down before my sword while the charging guards were still some distance away. Close behind them pursued the youth. At my back were the young girls, and as it was in their service that I fought, I remained standing there to meet my inevitable death, but with the determination to give such an account of myself as would long be remembered in the land of the First Born.

I noted the marvellous speed of the young red man as he raced after the guards. Never had I seen such speed in any Martian. His leaps and bounds were little short of those which my earthly muscles had produced to create such awe and respect on the part of the green Martians into whose hands I had fallen on that long-gone day that had seen my first advent upon Mars.

The guards had not reached me when he fell upon them from the rear, and as they turned, thinking from the fierceness of his onslaught that a dozen were attacking them, I rushed them from my side.

In the rapid fighting that followed I had little chance to note aught else than the movements of my immediate adversaries, but now and again I caught a fleeting glimpse of a purring sword and a lightly springing figure of sinewy steel that filled my heart with a strange yearning and a mighty but unaccountable pride.

On the handsome face of the boy a grim smile played, and ever and anon he threw a taunting challenge to the foes that faced him. In this and other ways his manner of fighting was similar to that which had always marked me on the field of combat.

Perhaps it was this vague likeness which made me love the boy, while the awful havoc that his sword played amongst the blacks filled my soul with a tremendous respect for him.

For my part, I was fighting as I had fought a thousand times before-now sidestepping a wicked thrust, now stepping quickly in to let my sword's point drink deep in a foeman's heart, before it buried itself in the throat of his companion.

We were having a merry time of it, we two, when a great body of Issus' own guards were ordered into the arena. On they came with fierce cries, while from every side the armed prisoners swarmed upon them.

For half an hour it was as though all hell had broken loose. In the walled confines of the arena we fought in an inextricable mass-howling, cursing, blood-streaked demons; and ever the sword of the young red man flashed beside me.

Slowly and by repeated commands I had succeeded in drawing the prisoners into a rough formation about us, so that at last we fought formed into a rude circle in the centre of which were the doomed maids.

Many had gone down on both sides, but by far the greater havoc had been wrought in the ranks of the guards of Issus. I could see messengers running swiftly through the audience, and as they passed the nobles there unsheathed their swords and sprang into the arena. They were going to annihilate us by force of numbers-that was quite evidently their plan.

I caught a glimpse of Issus leaning far forward upon her throne, her hideous countenance distorted in a horrid grimace of hate and rage, in which I thought I could distinguish an expression of fear. It was that face that inspired me to the thing that followed.

Quickly I ordered fifty of the prisoners to drop back behind us and form a new circle about the maidens.

"Remain and protect them until I return," I commanded.

Then, turning to those who formed the outer line, I cried, "Down with Issus! Follow me to the throne; we will reap vengeance where vengeance is deserved."

The youth at my side was the first to take up the cry of "Down with Issus!" and then at my back and from all sides rose a hoarse shout, "To the throne! To the throne!"

As one man we moved, an irresistible fighting mass, over the bodies of dead and dying foes toward the gorgeous throne of the Martian deity. Hordes of the doughtiest fighting-men of the First Born poured from the audience to check our progress. We mowed them down before us as they had been paper men.

"To the seats, some of you!" I cried as we approached the arena's barrier wall. "Ten of us can take the throne," for I had seen that Issus' guards had for the most part entered the fray within the arena.
