Noiselessly I gained the deck. The girl nodded to me to approach her. As I bent low she whispered to me to release her.

"I can aid you," she said, "and you will need all the aid available when they awaken."

"Some of them will awake in Korus," I replied smiling.

She caught the meaning of my words, and the cruelty of her answering smile horrified me. One is not astonished by cruelty in a hideous face, but when it touches the features of a goddess whose fine-chiselled lineaments might more fittingly portray love and beauty, the contrast is appalling.

Quickly I released her.

"Give me a revolver," she whispered. "I can use that upon those your sword does not silence in time."

I did as she bid. Then I turned toward the distasteful work that lay before me. This was no time for fine compunctions, nor for a chivalry that these cruel demons would neither appreciate nor reciprocate.

Stealthily I approached the nearest sleeper. When he awoke he was well on his journey to the bosom of Korus. His piercing shriek as consciousness returned to him came faintly up to us from the black depths beneath.

The second awoke as I touched him, and, though I succeeded in hurling him from the cruiser's deck, his wild cry of alarm brought the remaining pirates to their feet. There were five of them.

As they arose the girl's revolver spoke in sharp staccato and one sank back to the deck again to rise no more.

The others rushed madly upon me with drawn swords. The girl evidently dared not fire for fear of wounding me, but I saw her sneak stealthily and cat-like toward the flank of the attackers. Then they were on me.

For a few minutes I experienced some of the hottest fighting I had ever passed through. The quarters were too small for foot work. It was stand your ground and give and take. At first I took considerably more than I gave, but presently I got beneath one fellow's guard and had the satisfaction of seeing him collapse upon the deck.

The others redoubled their efforts. The crashing of their blades upon mine raised a terrific din that might have been heard for miles through the silent night. Sparks flew as steel smote steel, and then there was the dull and sickening sound of a shoulder bone parting beneath the keen edge of my Martian sword.

Three now faced me, but the girl was working her way to a point that would soon permit her to reduce the number by one at least. Then things happened with such amazing rapidity that I can scarce comprehend even now all that took place in that brief instant.

The three rushed me with the evident purpose of forcing me back the few steps that would carry my body over the rail into the void below. At the same instant the girl fired and my sword arm made two moves. One man dropped with a bullet in his brain; a sword flew clattering across the deck and dropped over the edge beyond as I disarmed one of my opponents and the third went down with my blade buried to the hilt in his breast and three feet of it protruding from his back, and falling wrenched the sword from my grasp.

Disarmed myself, I now faced my remaining foeman, whose own sword lay somewhere thousands of feet below us, lost in the Lost Sea.

The new conditions seemed to please my adversary, for a smile of satisfaction bared his gleaming teeth as he rushed at me bare-handed. The great muscles which rolled beneath his glossy black hide evidently assured him that here was easy prey, not worth the trouble of drawing the dagger from his harness.

I let him come almost upon me. Then I ducked beneath his outstretched arms, at the same time sidestepping to the right. Pivoting on my left toe, I swung a terrific right to his jaw, and, like a felled ox, he dropped in his tracks.

A low, silvery laugh rang out behind me.

"You are no thern," said the sweet voice of my companion, "for all your golden locks or the harness of Sator Throg. Never lived there upon all Barsoom before one who could fight as you have fought this night. Who are you?"

"I am John Carter, Prince of the House of Tardos Mors, Jeddak of Helium," I replied. "And whom," I added, "has the honour of serving been accorded me?"

She hesitated a moment before speaking. Then she asked:

"You are no thern. Are you an enemy of the therns?"

"I have been in the territory of the therns for a day and a half. During that entire time my life has been in constant danger. I have been harassed and persecuted. Armed men and fierce beasts have been set upon me. I had no quarrel with the therns before, but can you wonder that I feel no great love for them now? I have spoken."

She looked at me intently for several minutes before she replied. It was as though she were attempting to read my inmost soul, to judge my character and my standards of chivalry in that long-drawn, searching gaze.

Apparently the inventory satisfied her.

"I am Phaidor, daughter of Matai Shang, Holy Hekkador of the Holy Therns, Father of Therns, Master of Life and Death upon Barsoom, Brother of Issus, Prince of Life Eternal."

At that moment I noticed that the black I had dropped with my fist was commencing to show signs of returning consciousness. I sprang to his side. Stripping his harness from him I securely bound his hands behind his back, and after similarly fastening his feet tied him to a heavy gun carriage.

"Why not the simpler way?" asked Phaidor.

"I do not understand. What 'simpler way'?" I replied.

With a slight shrug of her lovely shoulders she made a gesture with her hands personating the casting of something over the craft's side.

"I am no murderer," I said. "I kill in self-defence only."

She looked at me narrowly. Then she puckered those divine brows of hers, and shook her head. She could not comprehend.

Well, neither had my own Dejah Thoris been able to understand what to her had seemed a foolish and dangerous policy toward enemies. Upon Barsoom, quarter is neither asked nor given, and each dead man means so much more of the waning resources of this dying planet to be divided amongst those who survive.

But there seemed a subtle difference here between the manner in which this girl contemplated the dispatching of an enemy and the tender-hearted regret of my own princess for the stern necessity which demanded it.

I think that Phaidor regretted the thrill that the spectacle would have afforded her rather than the fact that my decision left another enemy alive to threaten us.

The man had now regained full possession of his faculties, and was regarding us intently from where he lay bound upon the deck. He was a handsome fellow, clean limbed and powerful, with an intelligent face and features of such exquisite chiselling that Adonis himself might have envied him.

The vessel, unguided, had been moving slowly across the valley; but now I thought it time to take the helm and direct her course. Only in a very general way could I guess the location of the Valley Dor. That it was far south of the equator was evident from the constellations, but I was not sufficiently a Martian astronomer to come much closer than a rough guess without the splendid charts and delicate instruments with which, as an officer in the Heliumite Navy, I had formerly reckoned the positions of the vessels on which I sailed.

That a northerly course would quickest lead me toward the more settled portions of the planet immediately decided the direction that I should steer. Beneath my hand the cruiser swung gracefully about. Then the button which controlled the repulsive rays sent us soaring far out into space. With speed lever pulled to the last notch, we raced toward the north as we rose ever farther and farther above that terrible valley of death.

As we passed at a dizzy height over the narrow domains of the therns the flash of powder far below bore mute witness to the ferocity of the battle that still raged along that cruel frontier. No sound of conflict reached our ears, for in the rarefied atmosphere of our great altitude no sound wave could penetrate; they were dissipated in thin air far below us.
