“You thought that you could escape from Gapth, did you?” he cried, “but never; you might escape from the others, but not from me—no, not from Gapth.”
“I did the principal thing that I desired to do,” I replied, wishing to learn if Nah-ee-lah had escaped.
“What is that?” demanded Gapth.
“I succeeded in accomplishing the escape of my companion,” I replied.
He made a wry face at that. “If Gapth had been there a moment earlier she would not have escaped, either,” he said, and by that I knew that she had escaped, unless she had fallen back into the crater; and I was amply repaid for my own capture if it had won freedom for Nah-ee-lah.
“Although I did not escape this time,” I said, “I shall next time.”
He laughed a nasty laugh. “There will be no next time,” he said, “for we are taking you to the city, and once there, there is no escape, for this is the only avenue by which you can reach the outer world and once within the city you never can retrace your steps to the mouth of the tunnel.”
I was not so sure of that, myself, for my sense of direction and that of location are very well developed within me. The degree of perfection attained in orientation by many officers of the International Peace Fleet has been described as almost miraculous, and even among such as these my ability in this line was a matter of comment. I was glad, therefore, that the fellow had warned me, since now I should be particularly upon the watch for each slightest scrap of information that would fix in my memory whatever route I might be led over. From the cave in which I regained consciousness there was but a single route to the mouth of the tunnel, but from here on into the city I must watch every turn and fork and crossing and draw upon the tablets of my memory an accurate and detailed map of the entire route.
“We do not even have to confine our prisoners,” continued Gapth, “after we have so marked them that their ownership may always be determined.” “How do you mark them?” I asked. “With heated irons we make the mark of the owner here,” and he touched my forehead just above my eyes. “Pleasant,” I thought to myself, and then aloud: “Shall I belong to you?”
“I do not know,” he replied, “but you will belong to whomever The Twenty-four allot you.”
We moved on after we left the cave for a considerable period of time in silence. I was busy making mental notes of every salient feature that might be useful to me in retracing my steps, but I found nothing other than a winding and gently ascending corridor, without crossings or branches, until we reached the foot of a long flight of stone steps at the summit of which we emerged into a large chamber in the walls of which there must have been at least a dozen doorways, where, to my great disappointment, I was immediately blindfolded. They whirled me around then, but evidently it was done perfunctorily, since it was exactly one full turn and I was halted in my tracks facing precisely in the same direction that I had been before. This I was positive of, for our powers of orientation are often tested in this way in the air service. Then they marched me straight forward across the room through a doorway directly opposite that at which I had entered the chamber. I could tell when we left the larger chamber and entered the corridor from the different sound which our footsteps made. We advanced along this corridor ninety-seven paces, when we turned abruptly to the right and at the end of thirty-three paces emerged into another chamber, as I could easily tell again from the sound of our footsteps the instant we crossed the threshold. They led me about this chamber a couple of times with the evident intention of bewildering me, but in this they did not succeed, for when they turned again into a corridor I knew that it was the same corridor from which I had just emerged and that I was retracing my steps. This time they took me back thirty-three paces and then turned abruptly to the right. I could not but smile to myself when I realized that we were now continuing directly along the same corridor as that which we had entered immediately after they had first blindfolded me, their little excursion through the short corridor into the second chamber having been but a ruse to bewilder me. A moment later, at the foot of a flight of steps they removed the blind, evidently satisfied that there was now no chance of my being able to retrace my steps and find the main tunnel leading to the crater, while, as a matter of fact, I could easily have retraced every foot of it blindfolded.
From here on we climbed interminable stairways passed through numerous corridors and chambers, all of which were illuminated by the radium-bearing substance which coated their walls and ceilings, and then we emerged suddenly upon a terrace into the open air, and I obtained my first view of a lunar city. It was built around a crater, and the buildings were terraced back from the rim, the terraces being generally devoted to the raising of garden truck and the principal fruit-bearing trees and shrubs. The city extended upward several hundred feet, the houses, as I learned later, being built one upon another, the great majority of them, therefore, being without windows looking upon the outer world.
I was led along the terrace for a short distance, and during this brief opportunity for observation I deduced that the cultivated terraces lay upon the roofs of the tier of buildings next below. To my right I could see the terraced steps extending downward to the rim of the crater. Nearly all the terraces were covered with vegetation, and in numerous places I saw what appeared to be Va-gas feeding upon the plants, and this I later learned was the fact, and that the Kalkars, when they are able to capture members of the race of Va-gas, keep them in captivity and breed them as we breed cattle, for their flesh. It is necessary, to some extent, to change the diet of the Va-gas almost exclusively to vegetation, though this diet is supplemented by the flesh of the Kalkars, and their Laythean slaves who die, the Va-gas thus being compelled to serve the double purpose of producing flesh for the Kalkars and acting as their scavengers as well.
Upon my left were the faces of buildings, uniformly two stories in height, with an occasional slender tower rising fifteen, twenty or sometimes as high as thirty feet from the terraced roofs above. It was into one of these buildings that my captors led me after we had proceeded a short distance along the terrace, and I found myself in a large apartment in which were a number of male Kalkars, and at a desk facing the entrance a large, entirely bald man who appeared to be of considerable age. To this person I was led by Gapth, who narrated my capture and the escape of Nah-ee-lah.
The fellow before whom I had been brought questioned me briefly. He made no comment when I told him that I was from another world, but he examined my garments rather carefully and then after a moment turned to Gapth.
“We will hold him for questioning by The Twenty-four,” he said. “If he is not of Va-nah he is neither Kalkar nor Laythean, and consequently, he must be flesh of a lower order and therefore may be eaten.” He paused a moment and fell to examining a large book which seemed to be filled with plans upon which strange hieroglyphics appeared. He turned over several leaves, and finally coming evidently to the page he sought, he ran a forefinger slowly over it until it came to rest near the center of the plat. “You may confine him here,” he said to Gapth, “in chamber eight of the twenty-fourth section, at the seventh elevation and you will produce him upon orders from The Twenty-four when next they meet,” and then to me: “It is impossible for you to escape from the city, but if you attempt it, it may be difficult for us to find you again immediately and when we do you will be tortured to death as an example to other slaves. Go!” I went; following Gapth and the others who had conducted me to the presence of this creature. They led me back into the very corridor from which we had emerged upon the terrace and then straight into the heart of that amazing pile for fully half a mile, where they shoved me roughly into an apartment at the right of the corridor with the admonition that I stay there until I was wanted. I found myself in a dimly lighted, rectangular room, the air of which was very poor, and at the first glance I discovered that I was not alone, for upon a bench against the opposite wall sat a man. He looked up as I entered and I saw that his features were very fine and that he had black hair like Nah-ee-lah. He looked at me for a moment with a puzzled expression in his eyes and then he addressed me.
