"Why you had gone none could guess, for your princess still lived-"

"Thank God," I interrupted him. "I did not dare to ask you, for I feared I might have been too late to save her-she was very low when I left her in the royal gardens of Tardos Mors that long-gone night; so very low that I scarcely hoped even then to reach the atmosphere plant ere her dear spirit had fled from me for ever. And she lives yet?"

"She lives, John Carter."

"You have not told me where we are," I reminded him.

"We are where I expected to find you, John Carter-and another. Many years ago you heard the story of the woman who taught me the thing that green Martians are reared to hate, the woman who taught me to love. You know the cruel tortures and the awful death her love won for her at the hands of the beast, Tal Hajus.

"She, I thought, awaited me by the Lost Sea of Korus.

"You know that it was left for a man from another world, for yourself, John Carter, to teach this cruel Thark what friendship is; and you, I thought, also roamed the care-free Valley Dor.

"Thus were the two I most longed for at the end of the long pilgrimage I must take some day, and so as the time had elapsed which Dejah Thoris had hoped might bring you once more to her side, for she has always tried to believe that you had but temporarily returned to your own planet, I at last gave way to my great yearning and a month since I started upon the journey, the end of which you have this day witnessed. Do you understand now where you be, John Carter?"

"And that was the River Iss, emptying into the Lost Sea of Korus in the Valley Dor?" I asked.

"This is the valley of love and peace and rest to which every Barsoomian since time immemorial has longed to pilgrimage at the end of a life of hate and strife and bloodshed," he replied. "This, John Carter, is Heaven."

His tone was cold and ironical; its bitterness but reflecting the terrible disappointment he had suffered. Such a fearful disillusionment, such a blasting of life-long hopes and aspirations, such an uprooting of age-old tradition might have excused a vastly greater demonstration on the part of the Thark.

I laid my hand upon his shoulder.

"I am sorry," I said, nor did there seem aught else to say.

"Think, John Carter, of the countless billions of Barsoomians who have taken the voluntary pilgrimage down this cruel river since the beginning of time, only to fall into the ferocious clutches of the terrible creatures that to-day assailed us.

"There is an ancient legend that once a red man returned from the banks of the Lost Sea of Korus, returned from the Valley Dor, back through the mysterious River Iss, and the legend has it that he narrated a fearful blasphemy of horrid brutes that inhabited a valley of wondrous loveliness, brutes that pounced upon each Barsoomian as he terminated his pilgrimage and devoured him upon the banks of the Lost Sea where he had looked to find love and peace and happiness; but the ancients killed the blasphemer, as tradition has ordained that any shall be killed who return from the bosom of the River of Mystery.

"But now we know that it was no blasphemy, that the legend is a true one, and that the man told only of what he saw; but what does it profit us, John Carter, since even should we escape, we also would be treated as blasphemers? We are between the wild thoat of certainty and the mad zitidar of fact-we can escape neither."

"As Earth men say, we are between the devil and the deep sea, Tars Tarkas," I replied, nor could I help but smile at our dilemma.

"There is naught that we can do but take things as they come, and at least have the satisfaction of knowing that whoever slays us eventually will have far greater numbers of their own dead to count than they will get in return. White ape or plant man, green Barsoomian or red man, whosoever it shall be that takes the last toll from us will know that it is costly in lives to wipe out John Carter, Prince of the House of Tardos Mors, and Tars Tarkas, Jeddak of Thark, at the same time."

I could not help but laugh at him grim humour, and he joined in with me in one of those rare laughs of real enjoyment which was one of the attributes of this fierce Tharkian chief which marked him from the others of his kind.

"But about yourself, John Carter," he cried at last. "If you have not been here all these years where indeed have you been, and how is it that I find you here to-day?"

"I have been back to Earth," I replied. "For ten long Earth years I have been praying and hoping for the day that would carry me once more to this grim old planet of yours, for which, with all its cruel and terrible customs, I feel a bond of sympathy and love even greater than for the world that gave me birth.

"For ten years have I been enduring a living death of uncertainty and doubt as to whether Dejah Thoris lived, and now that for the first time in all these years my prayers have been answered and my doubt relieved I find myself, through a cruel whim of fate, hurled into the one tiny spot of all Barsoom from which there is apparently no escape, and if there were, at a price which would put out for ever the last flickering hope which I may cling to of seeing my princess again in this life-and you have seen to-day with what pitiful futility man yearns toward a material hereafter.

"Only a bare half-hour before I saw you battling with the plant men I was standing in the moonlight upon the banks of a broad river that taps the eastern shore of Earth's most blessed land. I have answered you, my friend. Do you believe?"

"I believe," replied Tars Tarkas, "though I cannot understand."

As we talked I had been searching the interior of the chamber with my eyes. It was, perhaps, two hundred feet in length and half as broad, with what appeared to be a doorway in the centre of the wall directly opposite that through which we had entered.

The apartment was hewn from the material of the cliff, showing mostly dull gold in the dim light which a single minute radium illuminator in the centre of the roof diffused throughout its great dimensions. Here and there polished surfaces of ruby, emerald, and diamond patched the golden walls and ceiling. The floor was of another material, very hard, and worn by much use to the smoothness of glass. Aside from the two doors I could discern no sign of other aperture, and as one we knew to be locked against us I approached the other.

As I extended my hand to search for the controlling button, that cruel and mocking laugh rang out once more, so close to me this time that I involuntarily shrank back, tightening my grip upon the hilt of my great sword.

And then from the far corner of the great chamber a hollow voice chanted: "There is no hope, there is no hope; the dead return not, the dead return not; nor is there any resurrection. Hope not, for there is no hope."

Though our eyes instantly turned toward the spot from which the voice seemed to emanate, there was no one in sight, and I must admit that cold shivers played along my spine and the short hairs at the base of my head stiffened and rose up, as do those upon a hound's neck when in the night his eyes see those uncanny things which are hidden from the sight of man.

Quickly I walked toward the mournful voice, but it had ceased ere I reached the further wall, and then from the other end of the chamber came another voice, shrill and piercing:

"Fools! Fools!" it shrieked. "Thinkest thou to defeat the eternal laws of life and death? Wouldst cheat the mysterious Issus, Goddess of Death, of her just dues? Did not her mighty messenger, the ancient Iss, bear you upon her leaden bosom at your own behest to the Valley Dor?

"Thinkest thou, O fools, that Issus wilt give up her own? Thinkest thou to escape from whence in all the countless ages but a single soul has fled?
