"Ah," said Zat Arras, "to what kindly circumstance am I indebted for the pleasure of this unexpected visit from the Prince of Helium?"

While he was speaking, one of my guards had removed the gag from my mouth, but I made no reply to Zat Arras: simply standing there in silence with level gaze fixed upon the Jed of Zodanga. And I doubt not that my expression was coloured by the contempt I felt for the man.

The eyes of those within the chamber were fixed first upon me and then upon Zat Arras, until finally a flush of anger crept slowly over his face.

"You may go," he said to those who had brought me, and when only his two companions and ourselves were left in the chamber, he spoke to me again in a voice of ice-very slowly and deliberately, with many pauses, as though he would choose his words cautiously.

"John Carter," he said, "by the edict of custom, by the law of our religion, and by the verdict of an impartial court, you are condemned to die. The people cannot save you-I alone may accomplish that. You are absolutely in my power to do with as I wish-I may kill you, or I may free you, and should I elect to kill you, none would be the wiser.

"Should you go free in Helium for a year, in accordance with the conditions of your reprieve, there is little fear that the people would ever insist upon the execution of the sentence imposed upon you.

"You may go free within two minutes, upon one condition. Tardos Mors will never return to Helium. Neither will Mors Kajak, nor Dejah Thoris. Helium must select a new Jeddak within the year. Zat Arras would be Jeddak of Helium. Say that you will espouse my cause. This is the price of your freedom. I am done."

I knew it was within the scope of Zat Arras' cruel heart to destroy me, and if I were dead I could see little reason to doubt that he might easily become Jeddak of Helium. Free, I could prosecute the search for Dejah Thoris. Were I dead, my brave comrades might not be able to carry out our plans. So, by refusing to accede to his request, it was quite probable that not only would I not prevent him from becoming Jeddak of Helium, but that I would be the means of sealing Dejah Thoris' fate-of consigning her, through my refusal, to the horrors of the arena of Issus.

For a moment I was perplexed, but for a moment only. The proud daughter of a thousand Jeddaks would choose death to a dishonorable alliance such as this, nor could John Carter do less for Helium than his Princess would do.

Then I turned to Zat Arras.

"There can be no alliance," I said, "between a traitor to Helium and a prince of the House of Tardos Mors. I do not believe, Zat Arras, that the great Jeddak is dead."

Zat Arras shrugged his shoulders.

"It will not be long, John Carter," he said, "that your opinions will be of interest even to yourself, so make the best of them while you can. Zat Arras will permit you in due time to reflect further upon the magnanimous offer he has made you. Into the silence and darkness of the pits you will enter upon your reflection this night with the knowledge that should you fail within a reasonable time to agree to the alternative which has been offered you, never shall you emerge from the darkness and the silence again. Nor shall you know at what minute the hand will reach out through the darkness and the silence with the keen dagger that shall rob you of your last chance to win again the warmth and the freedom and joyousness of the outer world."

Zat Arras clapped his hands as he ceased speaking. The guards returned.

Zat Arras waved his hand in my direction.

"To the pits," he said. That was all. Four men accompanied me from the chamber, and with a radium hand-light to illumine the way, escorted me through seemingly interminable tunnels, down, ever down beneath the city of Helium.

At length they halted within a fair-sized chamber. There were rings set in the rocky walls. To them chains were fastened, and at the ends of many of the chains were human skeletons. One of these they kicked aside, and, unlocking the huge padlock that had held a chain about what had once been a human ankle, they snapped the iron band about my own leg. Then they left me, taking the light with them.

Utter darkness prevailed. For a few minutes I could hear the clanking of accoutrements, but even this grew fainter and fainter, until at last the silence was as complete as the darkness. I was alone with my gruesome companions-with the bones of dead men whose fate was likely but the index of my own.

How long I stood listening in the darkness I do not know, but the silence was unbroken, and at last I sunk to the hard floor of my prison, where, leaning my head against the stony wall, I slept.

It must have been several hours later that I awakened to find a young man standing before me. In one hand he bore a light, in the other a receptacle containing a gruel-like mixture-the common prison fare of Barsoom.

"Zat Arras sends you greetings," said the young man, "and commands me to inform you that though he is fully advised of the plot to make you Jeddak of Helium, he is, however, not inclined to withdraw the offer which he has made you. To gain your freedom you have but to request me to advise Zat Arras that you accept the terms of his proposition."

I but shook my head. The youth said no more, and, after placing the food upon the floor at my side, returned up the corridor, taking the light with him.

Twice a day for many days this youth came to my cell with food, and ever the same greetings from Zat Arras. For a long time I tried to engage him in conversation upon other matters, but he would not talk, and so, at length, I desisted.

For months I sought to devise methods to inform Carthoris of my whereabouts. For months I scraped and scraped upon a single link of the massive chain which held me, hoping eventually to wear it through, that I might follow the youth back through the winding tunnels to a point where I could make a break for liberty.

I was beside myself with anxiety for knowledge of the progress of the expedition which was to rescue Dejah Thoris. I felt that Carthoris would not let the matter drop, were he free to act, but in so far as I knew, he also might be a prisoner in Zat Arras' pits.

That Zat Arras' spy had overheard our conversation relative to the selection of a new Jeddak, I knew, and scarcely a half-dozen minutes prior we had discussed the details of the plan to rescue Dejah Thoris. The chances were that that matter, too, was well known to him. Carthoris, Kantos Kan, Tars Tarkas, Hor Vastus, and Xodar might even now be the victims of Zat Arras' assassins, or else his prisoners.

I determined to make at least one more effort to learn something, and to this end I adopted strategy when next the youth came to my cell. I had noticed that he was a handsome fellow, about the size and age of Carthoris. And I had also noticed that his shabby trappings but illy comported with his dignified and noble bearing.

It was with these observations as a basis that I opened my negotiations with him upon his next subsequent visit.

"You have been very kind to me during my imprisonment here," I said to him, "and as I feel that I have at best but a very short time to live, I wish, ere it is too late, to furnish substantial testimony of my appreciation of all that you have done to render my imprisonment bearable.

"Promptly you have brought my food each day, seeing that it was pure and of sufficient quantity. Never by word or deed have you attempted to take advantage of my defenceless condition to insult or torture me. You have been uniformly courteous and considerate-it is this more than any other thing which prompts my feeling of gratitude and my desire to give you some slight token of it.

"In the guard-room of my palace are many fine trappings. Go thou there and select the harness which most pleases you-it shall be yours. All I ask is that you wear it, that I may know that my wish has been realized. Tell me that you will do it."
