The men visit a city, watching airplanes depart and arrive at an airport. They board a ship to cross a river and eventually reach their destination, a building. A man guides them to the "world map room." It seems they have an appointment there, although no details about it are provided. They observe books on the shelves and engage in some desultory conversation. Afterwards, they move to the courtyard to continue talking. They come across a pond containing a sunken ship, and the guide begins to explain its history. The book ends.
