whose wriggling thousands seethe the silent sea beneath the hurtling moons when the sun has gone and strange shapes walk through the Valley Dor.”
“We sent several Holy Therns to the silians to-day, then,” said Tars Tarkas, laughing.
“And so will your death be the more terrible when it comes,” said the maiden. “And come it will—you cannot escape.”
“One has escaped, centuries ago,” I reminded her, “and what has been done may be done again.”
“It is useless even to try,” she answered hopelessly.
“But try we shall,” I cried, “and you shall go with us, if you wish.”
“To be put to death by mine own people, and render my memory a disgrace to my family and my nation? A Prince of the House of Tardos Mors should know better than to suggest such a thing.”
Tars Tarkas listened in silence, but I could feel his eyes riveted upon me and I knew that he awaited my answer as one might listen to the reading of his sentence by the foreman of a jury.
What I advised the girl to do would seal our fate as well, since if I bowed to the inevitable decree of age-old superstition we must all remain and meet our fate in some horrible form within this awful abode of horror and cruelty.
“We have the right to escape if we can,” I answered. “Our own moral senses will not be offended if we succeed, for we know that the fabled life of love and peace in the blessed Valley of Dor is a rank and wicked deception. We know that the valley is not sacred; we know that the Holy Therns are not holy; that they are a race of cruel and heartless mortals, knowing no more of the real life to come than we do.
“Not only is it our right to bend every effort to escape—it is a solemn duty from which we should not shrink even though we know that we should be reviled and tortured by our own peoples when we returned to them.
“Only thus may we carry the truth to those without, and though the likelihood of our narrative being given credence is, I grant you, remote, so wedded are mortals to their stupid infatuation for impossible superstitions, we should be craven cowards indeed were we to shirk the plain duty which confronts us.
“Again there is a chance that with the weight of the testimony of several of us the truth of our statements may be accepted, and at least a compromise effected which will result in the dispatching of an expedition of investigation to this hideous mockery of heaven.”
Both the girl and the green warrior stood silent in thought for some moments. The former it was who eventually broke the silence.
“Never had I considered the matter in that light before,” she said. “Indeed would I give my life a thousand times if I could but save a single soul from the awful life that I have led in this cruel place. Yes, you are right, and I will go with you as far as we can go; but I doubt that we ever shall escape.”
I turned an inquiring glance toward the Thark.
“To the gates of Issus, or to the bottom of Korus,” spoke the green warrior; “to the snows to the north or to the snows to the south, Tars Tarkas follows where John Carter leads. I have spoken.”
“Come, then,” I cried, “we must make the start, for we could not be further from escape than we now are in the heart of this mountain and within the four walls of this chamber of death.”
“Come, then,” said the girl, “but do not flatter yourself that you can find no worse place than this within the territory of the therns.”
So saying she swung the secret panel that separated us from the apartment in which I had found her, and we stepped through once more into the presence of the other prisoners.
There were in all ten red Martians, men and women, and when we had briefly explained our plan they decided to join forces with us, though it was evident that it was with some considerable misgivings that they thus tempted fate by opposing an ancient superstition, even though each knew through cruel experience the fallacy of its entire fabric.
Thuvia, the girl whom I had first freed, soon had the others at liberty. Tars Tarkas and I stripped the bodies of the two therns of their weapons, which included swords, daggers, and two revolvers of the curious and deadly type manufactured by the red Martians.
We distributed the weapons as far as they would go among our followers, giving the firearms to two of the women; Thuvia being one so armed.
With the latter as our guide we set off rapidly but cautiously through a maze of passages, crossing great chambers hewn from the solid metal of the cliff, following winding corridors, ascending steep inclines, and now and again concealing ourselves in dark recesses at the sound of approaching footsteps.
Our destination, Thuvia said, was a distant storeroom where arms and ammunition in plenty might be found. From there she was to lead us to the summit of the cliffs, from where it would require both wondrous wit and mighty fighting to win our way through the very heart of the stronghold of the Holy Therns to the world without.
“And even then, O Prince,” she cried, “the arm of the Holy Thern is long. It reaches to every nation of Barsoom. His secret temples are hidden in the heart of every community. Wherever we go should we escape we shall find that word of our coming has preceded us, and death awaits us before we may pollute the air with our blasphemies.”
We had proceeded for possibly an hour without serious interruption, and Thuvia had just whispered to me that we were approaching our first destination, when on entering a great chamber we came upon a man, evidently a thern.
He wore in addition to his leathern trappings and jewelled ornaments a great circlet of gold about his brow in the exact centre of which was set an immense stone, the exact counterpart of that which I had seen upon the breast of the little old man at the atmosphere plant nearly twenty years before.
It is the one priceless jewel of Barsoom. Only two are known to exist, and these were worn as the insignia of their rank and position by the two old men in whose charge was placed the operation of the great engines which pump the artificial atmosphere to all parts of Mars from the huge atmosphere plant, the secret to whose mighty portals placed in my possession the ability to save from immediate extinction the life of a whole world.
The stone worn by the thern who confronted us was of about the same size as that which I had seen before; an inch in diameter I should say. It scintillated nine different and distinct rays; the seven primary colours of our earthly prism and the two rays which are unknown upon Earth, but whose wondrous beauty is indescribable.
As the thern saw us his eyes narrowed to two nasty slits.
“Stop!” he cried. “What means this, Thuvia?”
For answer the girl raised her revolver and fired point-blank at him. Without a sound he sank to the earth, dead.
“Beast!” she hissed. “After all these years I am at last revenged.”
Then as she turned toward me, evidently with a word of explanation on her lips, her eyes suddenly widened as they rested upon me, and with a little exclamation she started toward me.
“O Prince,” she cried, “Fate is indeed kind to us. The way is still difficult, but through this vile thing upon the floor we may yet win to the outer world. Notest thou not the remarkable resemblance between this Holy Thern and thyself?”
The man was indeed of my precise stature, nor were his eyes and features unlike mine; but his hair was a mass of flowing yellow locks, like those of the two I had killed, while mine is black and close cropped.
“What of the resemblance?” I asked the girl Thuvia. “Do you wish me with my black, short hair to pose as a yellow-haired priest of this infernal cult?”
She smiled, and for answer approached the body of the man she had slain, and kneeling beside it removed the circlet of gold from the forehead, and then to my utter amazement lifted the entire scalp bodily from the corpse’s head.
Rising, she advanced to my side and placing the
