The ridge-dormers are placed in pairs, at the very apex of the roof. They are opened and closed only once a year—in the spring and fall respectively; and are so arranged that no rain can enter.... if the air in the room is warmer than the outer air, it must rise and escape through the ridge-dormers.... If, during a heated spell, the lower windows and and doors are carefully kept shut, the air inside may be maintained several degrees cooler than the outer air.... the coolest air of the twenty-four hours will find its way through them, taking the place of the warmer air which escapes.... cooler air can be trapped in the house and held there during the day.... hot air, being lighter, does not descend into cool air.
