In each of the buildings are one hundred and fifty suites of five rooms, each suite having a floor area of sixteen hundred square feet, and every room having an outlook upon the street. A broad hall runs through the center of the building on every floor, lighted by means of plate-glass windows at each end, and also by three shafts, one hundred feet apart, running from cellar to roof. Every room is provided with steam, dry, and gas heat, and with gas and incandescent lights. Each suite has a household pneumatic tube service connecting with the store rooms in the basement, and with the kitchen and dining rooms in the seventeenth story. Each suite has also a cooking closet, with gas range, hot water, and steam pipes, porcelain-lined sinks, and pneumatic tubes for carrying away garbage. Six hydraulic elevators furnish ample accommodations for reaching every floor at any hour of the day or night. A network of perforated steel pipes is concealed in the walls and floors, with separate connections for each room with the great tanks on the roof, which are in turn connected both with the Croton water system, and with the great steel water main bringing water from Rockland Lake. In case of fire the walls and floors of one room, or of any number of rooms, can instantly be saturated with water, and twice in each week, at an appointed hour, a warm, gentle rain is made to descend for a sufficient length of time upon the trees and shrubs in the roof garden. Each suite has separate sewer connections, and each room is provided with registers in the wall, from which either hot air or cold air can be turned on or off at will, the hot air ascending from the furnaces, and the cold air being forced by a pumping engine from the refrigerating room in the basement. Those whose fate it has been to swelter on Manhattan Island in the dog days can appreciate the latter luxury. The fortunate occupant of a room in one of the Morning Blocks commands his temperature. Whether the thermometer registers thirty degrees below or one hundred degrees above zero outside, he can arrange the climate in his own room to suit himself, and _pater familias_ can connect a wire with the register in the parlor, and, if “Cholly” protracts his visits to Gladys to an improper hour, he can shut off the hot air, turn on a current from the refrigerator, and in ten minutes make the young man choose between departure and congealment.
