The dwelling places are all constructed of rock, some of which has a bluish cast and some of it has a pink cast. The rock trimming on some of the dwellings is light brown in color, while on others it has a greenish cast, having an appearance similar to an agate. The entrance of each home, but not the whole building, is made of the material that looked like pearls, the same as that used in the construction of the community social center building which so astounded us when we first saw it on our arrival here on Mars. Now Johnny asks what that material is? We are told it is a pearl-like rock formation which they have here and which is mined for building purposes. It comes in slab form from one inch to six inches in thickness and is broken up in various sizes according to the purpose for which it is to be used. It is not only beautiful but also very durable and nondeteriorating. On the whole of planet Mars there are no slums nor congested areas. Neither are there any run-down or neglected places. Beauty, cleanliness and order are expressed in everything everywhere. It could not be otherwise, considering their way of thinking and living. All the streets are very wide. We have not measured nor asked, but we judge that in the residential districts they are about two hundred feet wide as compared to the business district where they are five hundred feet in width. Here, however, there is no flowering lane down the center. It is not necessary. There is a considerable amount of timber growing in the mountain regions which they use in their building structures, we are told. Some of it is very hard and resembles mahogany. This is highly polished in every case. Then there is another kind of wood they have here which looks much like Earthly gum and is very hard. The grains within it are of various colors looking like marble. The trees from which this wood comes grow about one hundred fifty feet high, while the others grow to a height of seventy-five to one hundred feet. The light of the day is not the yellowish sort of white-yellow color that we have on Earth, but rather, it has a bluish cast to it. They have a big power plant here, too, that furnishes illumination and heat for the whole of the planet and the whole planet is well populated. The rural districts, they tell us, are just as well taken care of with all the conveniences as any city could be. All power is developed by the planetary government and is freely distributed to all places for all needs. It is generated from light, the same as that used by the airships. Here in the power plant, we notice, there is also a stand-by and Bob asked what it was for? The reason given was, that, should something happen to the apparatus generating their power from the light, they could resort to this sort of power, which was utilizing static electricity out of space.
