Scarce had they covered a hundred yards when the sound of many men shouting arose behind them. As they turned they saw a company of bowmen debouching upon the plain from the gate through which they had but just passed.

Upon the wall above the gate were a number of Lotharians, among whom Jav recognized Tario. The jeddak stood glaring at them, evidently concentrating all the forces of his trained mind upon them. That he was making a supreme effort to render his imaginary creatures deadly was apparent.

Jav turned white, and commenced to tremble. At the crucial moment he appeared to lose the courage of his conviction. The great banth turned back toward the advancing bowmen and growled. Carthoris placed himself between Thuvia and the enemy and, facing them, awaited the outcome of their charge.

Suddenly an inspiration came to Carthoris.

«Hurl your own bowmen against Tario's!» he cried to Jav. «Let us see a materialized battle between two mentalities.»

The suggestion seemed to hearten the Lotharian, and in another moment the three stood behind solid ranks of huge bowmen who hurled taunts and menaces at the advancing company emerging from the walled city.

Jav was a new man the moment his battalions stood between him and Tario. One could almost have sworn the man believed these creatures of his strange hypnotic power to be real flesh and blood.

With hoarse battle cries they charged the bowmen of Tario. Barbed shafts flew thick and fast. Men fell, and the ground was red with gore.

Carthoris and Thuvia had difficulty in reconciling the reality of it all with their knowledge of the truth. They saw utan after utan march from the gate in perfect step to reinforce the outnumbered company which Tario had first sent forth to arrest them.

They saw Jav's forces grow correspondingly until all about them rolled a sea of fighting, cursing warriors, and the dead lay in heaps about the field.

Jav and Tario seemed to have forgotten all else beside the struggling bowmen that surged to and fro, filling the broad field between the forest and the city.

The wood loomed close behind Thuvia and Carthoris. The latter cast a glance toward Jav.

«Come!» he whispered to the girl. «Let them fight out their empty battle-neither, evidently, has power to harm the other. They are like two controversialists hurling words at one another. While they are engaged we may as well be devoting our energies to an attempt to find the passage through the cliffs to the plain beyond.»

As he spoke, Jav, turning from the battle for an instant, caught his words. He saw the girl move to accompany the Heliumite. A cunning look leaped to the Lotharian's eyes.

The thing that lay beyond that look had been deep in his heart since first he had laid eyes upon Thuvia of Ptarth. He had not recognized it, however, until now that she seemed about to pass out of his existence.

He centred his mind upon the Heliumite and the girl for an instant.

Carthoris saw Thuvia of Ptarth step forward with outstretched hand. He was surprised at this sudden softening toward him, and it was with a full heart that he let his fingers close upon hers, as together they turned away from forgotten Lothar, into the woods, and bent their steps toward the distant mountains.

As the Lotharian had turned toward them, Thuvia had been surprised to hear Carthoris suddenly voice a new plan.

«Remain here with Jav,» she had heard him say, «while I go to search for the passage through the cliffs.»

She had dropped back in surprise and disappointment, for she knew that there was no reason why she should not have accompanied him. Certainly she should have been safer with him than left here alone with the Lotharian.

And Jav watched the two and smiled his cunning smile.

When Carthoris had disappeared within the wood, Thuvia seated herself apathetically upon the scarlet sward to watch the seemingly interminable struggles of the bowmen.

The long afternoon dragged its weary way toward darkness, and still the imaginary legions charged and retreated. The sun was about to set when Tario commenced to withdraw his troops slowly toward the city.

His plan for cessation of hostilities through the night evidently met with Jav's entire approval, for he caused his forces to form themselves in orderly utans and march just within the edge of the wood, where they were soon busily engaged in preparing their evening meal, and spreading down their sleeping silks and furs for the night.

Thuvia could scarce repress a smile as she noted the scrupulous care with which Jav's imaginary men attended to each tiny detail of deportment as truly as if they had been real flesh and blood.

Sentries were posted between the camp and the city. Officers clanked hither and thither issuing commands and seeing to it that they were properly carried out.

Thuvia turned toward Jav.

«Why is it,» she asked, «that you observe such careful nicety in the regulation of your creatures when Tario knows quite as well as you that they are but figments of your brain? Why not permit them simply to dissolve into thin air until you again require their futile service?»

«You do not understand them,» replied Jav. «While they exist they are real. I do but call them into being now, and in a way direct their general actions. But thereafter, until I dissolve them, they are as actual as you or I. Their officers command them, under my guidance. I am the general-that is all. And the psychological effect upon the enemy is far greater than were I to treat them merely as substanceless vagaries.

«Then, too,» continued the Lotharian, «there is always the hope, which with us is little short of belief, that some day these materializations will merge into the real-that they will remain, some of them, after we have dissolved their fellows, and that thus we shall have discovered a means for perpetuating our dying race.

«Some there are who claim already to have accomplished the thing. It is generally supposed that the etherealists have quite a few among their number who are permanent materializations. It is even said that such is Tario, but that cannot be, for he existed before we had discovered the full possibilities of suggestion.

«There are others among us who insist that none of us is real. That we could not have existed all these ages without material food and water had we ourselves been material. Although I am a realist, I rather incline toward this belief myself.

«It seems well and sensibly based upon the belief that our ancient forbears developed before their extinction such wondrous mentalities that some of the stronger minds among them lived after the death of their bodies-that we are but the deathless minds of individuals long dead.

«It would appear possible, and yet in so far as I am concerned I have all the attributes of corporeal existence. I eat, I sleep»-he paused, casting a meaning look upon the girl-«I love!»

Thuvia could not mistake the palpable meaning of his words and expression. She turned away with a little shrug of disgust that was not lost upon the Lotharian.

He came close to her and seized her arm.

«Why not Jav?» he cried. «Who more honourable than the second of the world's most ancient race? Your Heliumite? He has gone. He has deserted you to your fate to save himself. Come, be Jav's!»

Thuvia of Ptarth rose to her full height, her lifted shoulder turned toward the man, her haughty chin upraised, a scornful twist to her lips.

«You lie!» she said quietly, «the Heliumite knows less of disloyalty than he knows of fear, and of fear he is as ignorant as the unhatched young.»

«Then where is he?» taunted the Lotharian. «I tell you he has fled the valley. He has left you to your fate. But Jav will see that it is a pleasant one. To-morrow we shall return into Lothar at the head of my victorious army, and I shall be jeddak and you shall be my consort. Come!» And he attempted to crush her to his breast.
