I pressed the button far in and locked it. Then I set the lever at high speed and as the blacks came yelling upon us I slipped from the craft's deck and with drawn long-sword met the attack.

At the same moment a girl's shriek rang out behind me and an instant later, as the blacks fell upon me. I heard far above my head, and faintly, in Thuvia's voice: "My Prince, O my Prince; I would rather remain and die with-" But the rest was lost in the noise of my assailants.

I knew though that my ruse had worked and that temporarily at least Thuvia and Tars Tarkas were safe, and the means of escape was theirs.

For a moment it seemed that I could not withstand the weight of numbers that confronted me, but again, as on so many other occasions when I had been called upon to face fearful odds upon this planet of warriors and fierce beasts, I found that my earthly strength so far transcended that of my opponents that the odds were not so greatly against me as they appeared.

My seething blade wove a net of death about me. For an instant the blacks pressed close to reach me with their shorter swords, but presently they gave back, and the esteem in which they suddenly had learned to hold my sword arm was writ large upon each countenance.

I knew though that it was but a question of minutes before their greater numbers would wear me down, or get around my guard. I must go down eventually to certain death before them. I shuddered at the thought of it, dying thus in this terrible place where no word of my end ever could reach my Dejah Thoris. Dying at the hands of nameless black men in the gardens of the cruel therns.

Then my old-time spirit reasserted itself. The fighting blood of my Virginian sires coursed hot through my veins. The fierce blood lust and the joy of battle surged over me. The fighting smile that has brought consternation to a thousand foemen touched my lips. I put the thought of death out of my mind, and fell upon my antagonists with fury that those who escaped will remember to their dying day.

That others would press to the support of those who faced me I knew, so even as I fought I kept my wits at work, searching for an avenue of escape.

It came from an unexpected quarter out of the black night behind me. I had just disarmed a huge fellow who had given me a desperate struggle, and for a moment the blacks stood back for a breathing spell.

They eyed me with malignant fury, yet withal there was a touch of respect in their demeanour.

"Thern," said one, "you fight like a Dator. But for your detestable yellow hair and your white skin you would be an honour to the First Born of Barsoom."

"I am no thern," I said, and was about to explain that I was from another world, thinking that by patching a truce with these fellows and fighting with them against the therns I might enlist their aid in regaining my liberty. But just at that moment a heavy object smote me a resounding whack between my shoulders that nearly felled me to the ground.

As I turned to meet this new enemy an object passed over my shoulder, striking one of my assailants squarely in the face and knocking him senseless to the sward. At the same instant I saw that the thing that had struck us was the trailing anchor of a rather fair-sized air vessel; possibly a ten man cruiser.

The ship was floating slowly above us, not more than fifty feet over our heads. Instantly the one chance for escape that it offered presented itself to me. The vessel was slowly rising and now the anchor was beyond the blacks who faced me and several feet above their heads.

With a bound that left them gaping in wide-eyed astonishment I sprang completely over them. A second leap carried me just high enough to grasp the now rapidly receding anchor.

But I was successful, and there I hung by one hand, dragging through the branches of the higher vegetation of the gardens, while my late foemen shrieked and howled beneath me.

Presently the vessel veered toward the west and then swung gracefully to the south. In another instant I was carried beyond the crest of the Golden Cliffs, out over the Valley Dor, where, six thousand feet below me, the Lost Sea of Korus lay shimmering in the moonlight.

Carefully I climbed to a sitting posture across the anchor's arms. I wondered if by chance the vessel might be deserted. I hoped so. Or possibly it might belong to a friendly people, and have wandered by accident almost within the clutches of the pirates and the therns. The fact that it was retreating from the scene of battle lent colour to this hypothesis.

But I decided to know positively, and at once, so, with the greatest caution, I commenced to climb slowly up the anchor chain toward the deck above me. One hand had just reached for the vessel's rail and found it when a fierce black face was thrust over the side and eyes filled with triumphant hate looked into mine.

For an instant the black pirate and I remained motionless, glaring into each other's eyes. Then a grim smile curled the handsome lips above me, as an ebony hand came slowly in sight from above the edge of the deck and the cold, hollow eye of a revolver sought the centre of my forehead.

Simultaneously my free hand shot out for the black throat, just within reach, and the ebony finger tightened on the trigger. The pirate's hissing, "Die, cursed thern," was half choked in his windpipe by my clutching fingers. The hammer fell with a futile click upon an empty chamber.

Before he could fire again I had pulled him so far over the edge of the deck that he was forced to drop his firearm and clutch the rail with both hands.

My grasp upon his throat effectually prevented any outcry, and so we struggled in grim silence; he to tear away from my hold, I to drag him over to his death.

His face was taking on a livid hue, his eyes were bulging from their sockets. It was evident to him that he soon must die unless he tore loose from the steel fingers that were choking the life from him. With a final effort he threw himself further back upon the deck, at the same instant releasing his hold upon the rail to tear frantically with both hands at my fingers in an effort to drag them from his throat.

That little second was all that I awaited. With one mighty downward surge I swept him clear of the deck. His falling body came near to tearing me from the frail hold that my single free hand had upon the anchor chain and plunging me with him to the waters of the sea below.

I did not relinquish my grasp upon him, however, for I knew that a single shriek from those lips as he hurtled to his death in the silent waters of the sea would bring his comrades from above to avenge him.

Instead I held grimly to him, choking, ever choking, while his frantic struggles dragged me lower and lower toward the end of the chain.

Gradually his contortions became spasmodic, lessening by degrees until they ceased entirely. Then I released my hold upon him and in an instant he was swallowed by the black shadows far below.

Again I climbed to the ship's rail. This time I succeeded in raising my eyes to the level of the deck, where I could take a careful survey of the conditions immediately confronting me.

The nearer moon had passed below the horizon, but the clear effulgence of the further satellite bathed the deck of the cruiser, bringing into sharp relief the bodies of six or eight black men sprawled about in sleep.

Huddled close to the base of a rapid fire gun was a young white girl, securely bound. Her eyes were widespread in an expression of horrified anticipation and fixed directly upon me as I came in sight above the edge of the deck.

Unutterable relief instantly filled them as they fell upon the mystic jewel which sparkled in the centre of my stolen headpiece. She did not speak. Instead her eyes warned me to beware the sleeping figures that surrounded her.
