Now it had no floor of blue, as it had had before, but only a corridor perhaps wide enough to allow the passage 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.
he 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.
