"Yes, I shall be happy to," she replied. "In the meantime, I want you to know that my father has made an application for a license for you. You will soon be called to our traffic bureau and instructed how to operate our planes, and about our traffic rules. When you have mastered both, you may select your plane and travel about by yourself. For short distances, we either walk or use underground conveyances. Now we will ride back to my home by underground. "Our subway transits cover most of our city, going north and south and east and west; every community has its stop-offs, both for freight and for passenger trains." We were by now on the same street as the community court. We went down the escalator at the corner to the passenger train platform. In place of a ticket window, a trestle, or a coin deposit slot, I saw a very pleasingly decorated space with comfortable seats, an attendant who was very anxious to make us comfortable, and clean comfort stations, which we could safely use without the fear of being bludgeoned and robbed. The train soon arrived; the conductor with courtesy led us to two individual seats similar to those in our Pullman cars. Each seat had a little stand or table upon which were the latest magazines and newspapers. But we were interested in our conversation, and paid no attention to the news of the day. Xora showed me a daily bulletin printed by her community. She told me that every zone in every city has its own daily newspaper and radio station. I examined it with interest. The east side of this city was divided into three zones, and so was the west side. There were also general dailies for every race on the planet covering all of the globe news or intercontinental happenings without any display, classified or other advertisements. "We have full liberty of the press, radio, pictures and television," Xora said. "Our government has no right to censor them unless for unmoral causes. Otherwise their freedom is inviolable. We are at liberty to think, talk, broadcast, write about, and criticize our government executives, or our political, and economic defects, from the highest to the lowest, and state our opinions without reservation. "We give and accept criticism in a friendly spirit, but we are very careful not to make libelous statements." We had now reached our community, and the conductor signaled for a stop. He led us out to a platform near their commissary department, a very large store with food and beverage of every kind displayed on white monel shelves. Inside the spic and span interiors were attendants busy taking care of their customers. I again said, "During my short visit here I cannot help but observe everywhere the unusual cleanliness in your homes, on your walks, in your station, and on your subway cars, and in the neat appearance of all your people, both young and old. It seems to be an inborn habit of you people of Mars. How did it begin?"
