Over to his left the bluely glowing wall reached up to invisible immensity. But as he would have pa.s.sed along the wall, the rent opened again, effectually barring his way.

Beyond the rent he could see a vast continuation of the cavern, and he felt that, could they only pa.s.s the rent, they might reach a place where the heat was not so unbearable, and they could stay and talk in comfort.

Releasing Jaska, he stepped back and prepared to leap the spot where the rent had been. High he jumped, and far, surprised at the length of his own leap. He landed lightly, far beyond the area where the rent had been, and even as he landed, a rent opened again at his feet, thus effectually barring further progress!

"It could just as easily," he told himself, "have opened under my feet, and dropped me into the abyss!"

From behind him came the sudden sound of screaming. He whirled to look back, to see Jaska standing there, arms outstretched toward him, her eyes wide with fear and horror, and as he stood watching, she raced to him, unmindful of abysses that might open under her feet, and flung herself into his arms.

"Come back!" she moaned. "Come back! Don't you see? _They_ don't wish you to explore further! We are in their power, and must simply await their pleasure, whoever or whatever they are! They see all we do!"

So they turned back, and stood against the door which held them prisoners; and the heat of the place seemed to enter into them, to gnaw at their very vitals. After a time Sarka found himself almost tearing at his throat, fighting for breath.

Gasping, the tears bathing their cheeks until even their tears and their perspiration would flow no more, they huddled now just inside the ma.s.sive stone door, arms about each other, and almost prayed for death. Sarka at least prayed for death for both of them; but Jaska prayed for a way of deliverance, prayed that herself and Sarka might somehow win free, and be together again.

Sarka, who knew little of women, marveled at the grandeur of her courage, and wondered that he really knew this radiant woman so little. He compared her in his mind with the unclothed woman who had ordered them here as prisoners, and it came to him that Jaska was all perfection, all tender womanhood, while the Radiant Woman was a monster, without soul or compa.s.sion--a creature of horror who mocked G.o.d with her outward seeming of perfection.

Jaska read his thoughts, and smiled wanly to herself, and Sarka wondered how, suffering as he knew she must be suffering, she could find the courage to smile.

Then, for a time, the two became comatose, mastered by the blue heat, and in dreamlike imaginings wandered in strange fields which could only, to these two, have been racial memories, since neither had ever seen such fields. There were cool streams, all a-murmur, and breezes which cooled their sun-tanned cheeks. Water touched their tongues, and cooled their whole bodies as they gratefully imbibed it.

In their wanderings, in which Sarka was a faun and Jaska a nymph, they talked together in a language which only these two comprehended--a language which dealt in figures of speech, a language which depended upon handclasps for periods, glances of the eyes for commas, and the singing of their hearts for complete understanding.

Then a cool breeze, cool by comparison, caressed their pain-distorted cheeks, and the Gnomes came in, found them lying there, and clucked endlessly as though wondering what to do with them.

From hand to tiny hand, their feet serving as hands, the Gnomes pa.s.sed garments--garments of the Gens of Dalis, and clothed again the two whom the Place of the Blue Light had all but slain. Of that ghastly experiment Sarka retained but one real memory....

That bluish light, in the midst of the abyss, shifting and swaying like blue serpents swimming in Hades ... that bluish light of the Cone, which he had broken up for a brief moment by the use of his ray director. Was this bluish light in the abyss the source of the light in the Cone? If one were to destroy it at its source....

The two regained consciousness completely as the triangular door closed behind Sarka and Jaska and the Gnomes, and they were taken into the refreshing coolness of the tunnel, led back again in the direction of the room where they had seen the Radiant Woman. Both Jaska and Sarka noticed that they were clothed in new clothing, and a shy blush tinged the cheeks of Jaska as her eyes met those of Sarka.

This time they entered the vast chamber of radiance behind the first triangular door, and were forced to their knees to do obeisance to the Radiant Woman, who sat on a gleaming yellow stone for dais! The guards who forced Sarka and Jaska to their knees, were clothed in the green of the Gens of Dalis, and Dalis himself, his face stern, but bearing no sign of recognition of these two, stood at the right hand of the Radiant Woman!

"You come to us as spies," the thought of the Radiant Woman impinged upon the brains of Sarka and of Jaska, "and as spies you should be given to the Cone. But if you swear eternal allegiance to me, to obey me in all things, to forego your allegiance to Earth, your lives will be spared! What say you?"

Boldly Sarka stared into the almost opaque eyes of the woman. Then his glance went to the face of Dalis.

"What," he asked boldly, in the language of Earth, "does the traitor Dalis say?"

"I have sworn allegiance to Luar, who addresses you, and am her ally in all things! I have but one addition to make to what she says: Jaska belongs to me!"

The sudden leering grin of Dalis was hideous.

Sarka peered at Jaska, framing his answer. But Jaska spoke first.

"For myself, O Dalis," she said swiftly, "I can answer in but one way.

Return me to the Place of the Blue Light, and forget me there!"

Sarka smiled, while his heart leaped with joy.

"And I, O Luar," he said mentally to the Radiant Woman, "prefer death with Jaska, at the Place of the Blue Light, than life as a traitor to the world of my nativity!"

Instantly Luar began the clucking sound which was the language of the Gnomes, at the same time allowing her thoughts as she spoke to impress themselves upon the brains of the prisoners.

"Take them away! Take them to the Cavern of the Cone, and when they have suffered as much as such inferior beings are capable of suffering, thrust them into the base of the Cone!"

CHAPTER XVI

_Cavern of the Cone_

The Gnomes had been bidden to take the prisoners to the Cavern of the Cone, but to the surprise of Sarka and Jaska, they were taken back to the Place of the Blue Light! This time the Gnomes entered the place with them, closing and securing the door behind them.

But the Place of the Blue Light had changed!

Now it had no floor of blue, as it had had before, but only a corridor perhaps wide enough to allow the pa.s.sage of four grown men, walking side by side, while the abyss of which the two had got but the merest hint through the opening and closing rents filled all the center of the place!

The Gnomes seemed impervious to the unendurable heat, and these, moving together, one behind the other, one beside the other, one atop the other, formed a living wall between Sarka and Jaska and the rim of the flaming blue abyss, to protect them from the heat.

Yet through the bodies of this living wall of Gnomes, a wall which was higher than the heads of Sarka and Jaska, the heat forced its way to the prisoners, and burned them anew with its agony.

To what dread rendezvous were they going? Where, save for the few guards at the house of Luar, were the people of the Gens of Dalis?

Sarka felt, somehow, that the answers to all these questions would soon be made manifest, and a feeling of exaltation he could not explain was possessing him as he advanced. Around the corridor, whose one side was the wall reaching up to invisibility, whose other side dropped off into the abyss, the Gnomes herded the prisoners.

The leader of the Gnomes was again the Gnome who had first leaped upon Jaska to examine her curiously. Now, watching the lidless eyes of this being, Sarka fancied he could detect a hint of some expression. The Gnome was excited at some prospect, some climax which they were approaching. What? On and on they moved. The blue flames from the abyss, roaring in a way that neither of the prisoners had ever experienced, reached upward in searing tongues toward the invisible roof of this place.

Then, when they had progressed far from the door of entry, Sarka gasped at a new manifestation. Out of the abyss, some distance ahead, came a gleaming thing, something that had apparently evolved itself out of the flames of the abyss. Blue of color it was, because of the flames from the pit; but Sarka recognized it with a start which he could not suppress nor understand.

It was one of those cubes, such as he and Jaska had seen at the lip of the Moon-crater! As they approached, guided by the Gnomes, other cubes appeared out of the abyss, others in numbers swiftly augmented, until a veritable battalion of them had marshalled itself, there at the lip of the abyss.

Straight toward these cubes the Gnomes led Sarka and Jaska, and when they had reached the center of the group, they halted, forming a circle, still a wall to mask the prisoners from the heat of the abyss.

The leader of the Gnomes stopped with his face, his lidless eyes, close to one of the cubes.

For a moment he paused thus, and Sarka felt sure that somehow the Gnome was holding thought converse with the cube; but, try as he might, he could find no meaning in the weird conversation for himself.

It was oddly like listening to a conversation in a code beyond his knowledge.
