He led me to a closet with a continuous moving escalator dumb-waiter. "After our meal we place our dishes, silverware, and glassware, all of which have our name and number, on trays going down. When they reach the bottom, they automatically land on a conveyor belt which takes them directly to the central dishwashing and sterilizing machine; they come back, clean and sanitary, the same way." "What do you do with your garbage and rubbish?" He took hold of the knob of a small door in the wall beside the dumb waiter. "Oh," I said, "that's your incinerator." "No," he replied, "we do not burn such valuable materials. We put our garbage into paper bags, seal it, and throw it into this opening. It reaches a garbage car which takes it to a large factory where it is turned into fertilizer. Our rubbish is wrapped up and sent down the dumb-waiter. The belt conveyor takes it to the assorting room, and again by belt conveyors for long distances to our factories. Very little is wasted. "The kitchen in our home is seldom used. Underneath the court there is a large central kitchen, where any housewife can have her dinner cooked. She either just brings her raw food to the chef, or gives him directions over the phone, telling him for how many people and the time to be served. If the chef needs raw foods, he sends to the commissary department. "The commissary department supplies foods and beverages to all the residents of a community of five or more courts. It is also an ordering and receiving station from our main depots, which you have seen from the air. Daily supplies are shipped from the depot by our underground freight cars. Emergency shipments are made by messenger planes." "Does the commissary department ever run short of supplies because of an unusual demand?" I asked. "If it does, it can then requisition from another nearby department," he answered. "If people are inclined to be gluttonous, and it happens at times, even here, we ration them. That situation doesn't arise frequently, however, and when it does, we study the individual to find out what causes this unhealthy habit and help him to eliminate it. Individuals are very quickly cured from such an unhealthy inclination. "In the court along the kitchen, there is a public dining room where each family has a permanently reserved table. Menus are made up daily, by competent dietitians, who offer nourishing dishes adapted to the special needs of age, activity, and physical condition of the individual. When we wish a specially cooked dinner, we must notify our chef about the change of our menu. Sometimes my wife cooks a special dinner herself, in one of the small kitchenettes adjoining this large kitchen. It is only when we have special company that we dine in our homes."
