QUOTE : Air and earth form an anthill traversed, level upon level, by roads live with traffic. Air trains, ground trains, underground trains, people mailed through tubes special-delivery, and chains of cars race along horizontally, while express elevators pump masses of people vertically from one traffic level to another; at the junctions, people leap from one vehicle to the next, instantly sucked in and snatched away by the rhythm of it, which makes a syncope, a pause, a little gap of twenty seconds during which a word might be hastily exchanged with someone else. Questions and answers synchronize like meshing gears; everyone has only certain fixed tasks.
