The chieftain of the white race isn't a bit surprised, so he must have known there were other people living in the valley. But all the passengers alike, including the two chieftains, are almost speechless with the thrill and wonder of thus flying over their homeland. We have been observing them very closely for their reactions. So we continue flying farther yet up the valley. In the distance we see a very large settlement, almost like a city. It might be one. When this came into view, the chieftain of the white ones was very much surprised as were all the others. It seems none of them knew it was there. We figure this city is about four hundred to five hundred miles up the valley from the village of our white native companions. We have crossed a few low ranges of mountains in finding this place. Dr. Johnston has suggested that we fly over this place and see what it is. So we do. It appears to be a city of about twenty thousand population. We are directly over it and are lowering for a better view. We have lowered to within seven hundred feet of the city but we seem to be frightening everybody down there with our noise for we see the people clearing the open spaces for cover. We have circled the vicinity several times trying to find a place in which to land, for we would like to see more of this city and the people living here. But there is no possible landing place here in this narrow valley, so we are going back up. We are turning towards our original landing field on the plateau instead of going any farther at this time, since we don't know how long we will stay on the Moon and we have a hunch to preserve the fuel. Rather than return over the same territory we have come, George suggests that we take the light side to see what is there. To our surprise we find ourselves flying over quite a number of large settlements which are discernible from the air. Coming this way, Bob has had to rise to an altitude of forty thousand feet for we are encountering mountain peaks which are around thirty thousand to thirty-two thousand feet elevation. In each case the villages of the people living on the light side are of cliff dweller type, half way up the mountains from the floor of the valley. Through this entire area there is very little vegetation, while the mountains themselves seem to be of volcanic origin and bare of trees or brush. We have reached our starting place and are landing again. As our passengers leave the ship they try to thank us by much chattering and many gestures with their hands, indicating a great deal of excitement and joyousness, as it appears to us. Both groups of people who had been left behind when we went for our trip were still there awaiting our return and they all gathered around the ship when it landed, looking upon it with amazement.
