For several minutes the Lotharian eyed his prisoner, for such Carthoris now realized himself to be.

«I am half convinced that you are real,» he said at last.

Carthoris laughed.

«Of course I am real,» he said. «What caused you to doubt it? Can you not see me, feel me?»

«So may I see and feel the bowmen,» replied Jav, «and yet we all know that they, at least, are not real.»

Carthoris showed by the expression of his face his puzzlement at each new reference to the mysterious bowmen-the vanishing soldiery of Lothar.

«What, then, may they be?» he asked.

«You really do not know?» asked Jav.

Carthoris shook his head negatively.

«I can almost believe that you have told us the truth and that you are really from another part of Barsoom, or from another world. But tell me, in your own country have you no bowmen to strike terror to the hearts of the green hordesmen as they slay in company with the fierce banths of war?»

«We have soldiers,» replied Carthoris. «We of the red race are all soldiers, but we have no bowmen to defend us, such as yours. We defend ourselves.»

«You go out and get killed by your enemies!» cried Jav incredulously.

«Certainly,» replied Carthoris. «How do the Lotharians?»

«You have seen,» replied the other. «We send out our deathless archers-deathless because they are lifeless, existing only in the imaginations of our enemies. It is really our giant minds that defend us, sending out legions of imaginary warriors to materialize before the mind's eye of the foe.

«They see them-they see their bows drawn back-they see their slender arrows speed with unerring precision toward their hearts. And they die-killed by the power of suggestion.»

«But the archers that are slain?» exclaimed Carthoris. «You call them deathless, and yet I saw their dead bodies piled high upon the battlefield. How may that be?»

«It is but to lend reality to the scene,» replied Jav. «We picture many of our own defenders killed that the Torquasians may not guess that there are really no flesh and blood creatures opposing them.

«Once that truth became implanted in their minds, it is the theory of many of us, no longer would they fall prey to the suggestion of the deadly arrows, for greater would be the suggestion of the truth, and the more powerful suggestion would prevail-it is law.»

«And the banths?» questioned Carthoris. «They, too, were but creatures of suggestion?»

«Some of them were real,» replied Jav. «Those that accompanied the archers in pursuit of the Torquasians were unreal. Like the archers, they never returned, but, having served their purpose, vanished with the bowmen when the rout of the enemy was assured.

«Those that remained about the field were real. Those we loosed as scavengers to devour the bodies of the dead of Torquas. This thing is demanded by the realists among us. I am a realist. Tario is an etherealist.

«The etherealists maintain that there is no such thing as matter-that all is mind. They say that none of us exists, except in the imagination of his fellows, other than as an intangible, invisible mentality.

«According to Tario, it is but necessary that we all unite in imagining that there are no dead Torquasians beneath our walls, and there will be none, nor any need of scavenging banths.»

«You, then, do not hold Tario's beliefs?» asked Carthoris.

«In part only,» replied the Lotharian. «I believe, in fact I know, that there are some truly ethereal creatures. Tario is one, I am convinced. He has no existence except in the imaginations of his people.

«Of course, it is the contention of all us realists that all etherealists are but figments of the imagination. They contend that no food is necessary, nor do they eat; but any one of the most rudimentary intelligence must realize that food is a necessity to creatures having actual existence.»

«Yes,» agreed Carthoris, «not having eaten to-day I can readily agree with you.»

«Ah, pardon me,» exclaimed Jav. «Pray be seated and satisfy your hunger,» and with a wave of his hand he indicated a bountifully laden table that had not been there an instant before he spoke. Of that Carthoris was positive, for he had searched the room diligently with his eyes several times.

«It is well,» continued Jav, «that you did not fall into the hands of an etherealist. Then, indeed, would you have gone hungry.»

«But,» exclaimed Carthoris, «this is not real food-it was not here an instant since, and real food does not materialize out of thin air.»

Jav looked hurt.

«There is no real food or water in Lothar,» he said; «nor has there been for countless ages. Upon such as you now see before you have we existed since the dawn of history. Upon such, then, may you exist.»

«But I thought you were a realist,» exclaimed Carthoris.

«Indeed,» cried Jav, «what more realistic than this bounteous feast? It is just here that we differ most from the etherealists. They claim that it is unnecessary to imagine food; but we have found that for the maintenance of life we must thrice daily sit down to hearty meals.

«The food that one eats is supposed to undergo certain chemical changes during the process of digestion and assimilation, the result, of course, being the rebuilding of wasted tissue.

«Now we all know that mind is all, though we may differ in the interpretation of its various manifestations. Tario maintains that there is no such thing as substance, all being created from the substanceless matter of the brain.

«We realists, however, know better. We know that mind has the power to maintain substance even though it may not be able to create substance-the latter is still an open question. And so we know that in order to maintain our physical bodies we must cause all our organs properly to function.

«This we accomplish by materializing food-thoughts, and by partaking of the food thus created. We chew, we swallow, we digest. All our organs function precisely as if we had partaken of material food. And what is the result? What must be the result? The chemical changes take place through both direct and indirect suggestion, and we live and thrive.»

Carthoris eyed the food before him. It seemed real enough. He lifted a morsel to his lips. There was substance indeed. And flavour as well. Yes, even his palate was deceived.

Jav watched him, smiling, as he ate.

«Is it not entirely satisfying?» he asked.

«I must admit that it is,» replied Carthoris. «But tell me, how does Tario live, and the other etherealists who maintain that food is unnecessary?»

Jav scratched his head.

«That is a question we often discuss,» he replied. «It is the strongest evidence we have of the non-existence of the etherealists; but who may know other than Komal?»

«Who is Komal?» asked Carthoris. «I heard your jeddak speak of him.»

Jav bent low toward the ear of the Heliumite, looking fearfully about before he spoke.

«Komal is the essence,» he whispered. «Even the etherealists admit that mind itself must have substance in order to transmit to imaginings the appearance of substance. For if there really was no such thing as substance it could not be suggested-what never has been cannot be imagined. Do you follow me?»

«I am groping,» replied Carthoris dryly.

«So the essence must be substance,» continued Jav. «Komal is the essence of the All, as it were. He is maintained by substance. He eats. He eats the real. To be explicit, he eats the realists. That is Tario's work.

«He says that inasmuch as we maintain that we alone are real we should, to be consistent, admit that we alone are proper food for Komal. Sometimes, as to-day, we find other food for him. He is very fond of Torquasians.»

«And Komal is a man?» asked Carthoris.

«He is All, I told you,» replied Jav. «I know not how to explain him in words that you will understand. He is the beginning and the end. All life emanates from Komal, since the substance which feeds the brain with imaginings radiates from the body of Komal.
