As we approached the city, the base of which we must skirt in order to reach the crater beyond, I was able to obtain a better idea of the dimensions and methods of construction of this great interior lunar city, the base of which was roughly circular and about six miles in diameter, ranging from a few hundred to a thousand feet above the level of the plateau. The base of the city appeared to be the outer wall of an ancient extinct volcano, the entire summit of which had been blown off during some terrific eruption of a bygone age. Upon this base the ancient Laytheans had commenced the construction of their city, the houses of which rose one upon another as did those of the Kalkar city from which we had just escaped. The great age of Laythe was attested by the tremendous height to which these superimposed buildings had arisen, the loftiest wall of Laythe now rising fully a mile above the floor of the plateau. Narrow terraces encircled the periphery of the towering city, and as we approached more closely I saw doors and windows opening upon the terraces and figures moving to and fro, the whole resembling closely an enormous hive of bees. When we had reached a point near the base of the city, I saw that we had been discovered, for directly above us there were people at various points who were unquestionably looking down at us and commenting upon us. “They have seen us from above,” I said to Moh-goh, “why don’t you hail them?” “They take us for Kalkars,” he replied. “It is easier for us to enter the city by way of the tunnel, where I shall have no difficulty in establishing my identity.” “If they think we are Kalkars,” I said, “will they not attack us?” “No,” he replied, “Kalkars often pass Laythe. If they do not try to enter the city, we do not molest them.” “Your people fear them, then?” I asked. “It practically amounts to that,” he replied. “They greatly outnumber us, perhaps a thousand to one, and as they are without justice, mercy or honor we try not to antagonize them unnecessarily.” We came at length to the mouth of the crater, and here Moh-goh looped his rope about the base of a small tree growing close to the rim and slipped down to the opening of the tunnel directly beneath. I followed his example, and when I was beside him Moh-goh pulled the rope in, coiled it about his waist, and we set off along the passageway leading toward Laythe.
