gered was he by the fact that Quetzalcoatl, of Aztecan myth, might exist as a sentient creature here in this cavern world, that he had little heart left for exploring other wonders.
NEVERTHELESS, he presently pushed open the new door before which they had paused, and behind it found, as he had expected, the Duca's living quarters.
These were as severe as the jewel chamber had been gorgeous. A thin pallet spread upon a frame of wood formed the bed, and beside it stood a single stiff chair. That was all. The walls of glistening obsidion were bare.
There was, however, a door in one circular wall, and as Kirby flung this open, his previous disappointment changed to delight. For shelves along the walls of the small chamber held roll after roll of parchment covered with script. And in one corner lay six undamaged, almost new Mannlichers and several hundred rounds of ammunition!
"Naida," he exclaimed, "do you know what those are?"
"I suppose that they are weapons of the sort you used against the ape-men this morning?"
Kirby grinned.
"They are the same kind I used, and then some. With these weapons we can do what we never could with the smaller one. How did they get here?"
"They came when I was much younger," Naida answered with a shade of sadness in her voice. "The men who had them penetrated the Valley of the Geyser, coming by a different route from the one you followed. When the Duca learned they were there, he sent such men of the race as were still able to fight to kill them. That order of the Duca's was one of the first things to turn me against him. The men were not harming us, and they should have been permitted to go away. But the Duca insisted that they be killed, and in the fight were lost eight of our youngest and strongest men."
KIRBY stooped to inspect the rifles.
"Has no one learned to use these weapons?"
"No," Naida answered. "The Duca kept them for himself."
"We think," put in Ivana, "that he hoped to learn to use them, and was afraid for us to have the knowledge."
Kirby filled one of the magazines, and felt the heft of the gun with pleasure.
"Very well," he said. "It looks to me as though your time to learn the art of shooting has come at last. Come, I think we had better be getting back downstairs."
Kirby took three guns himself, and with the others lugging the rest, they started back. The parchment rolls, he decided, must be left for examination later on.
They were all elated when they rejoined the girls in the prayer chamber, and high spirits were still further increased by the report, promptly given, that all had remained quiet in the amphitheatre. Save only for the presence of Elana, radiant and calm in death, the give and take of questions would have been accompanied by actual gaiety.
But the time of peace did not last much longer. While Naida was in the midst of answering incessant questions about the wonders of the jewel chamber, Kirby heard a sound from below, and suddenly went over to the downward-winding steps.
"Listen," he called sharply back to the others.
He had not been mistaken. Many footsteps echoed from the amphitheatre, and he made out that the caciques were coming toward the bolted gate at the foot of the steps. While he listened, and Naida came eagerly to his side, silence fell.
But then clear words came up to them.
"Let the upper-world man come to the foot of the steps," called the Duca. "I have an offer to make him!"
