How few people, even among the supposedly well educated, can give an intelligent explanation of the qualities of a design! ...the essential ones ...are necessary in order that the design may be worthy to be classed at all as a work of art. Among the essential qualities are reason, unity, harmony, clarity, and variety. Among the desirable qualities are imagination, interest, refinement, simplicity, dignity, and style.

They are simple, easy to acquire, and should be taught with the alphabet.
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.
Disadvantages... can be entirely removed by... the ridge-dormer. By its use space in the roof, otherwise of little value, becomes the most desirable. Instead of being gloomy, stuffy and hot, the dormers render it perfectly ventilated, light at all times, and cool in hot weather. In frame buildings, it is not so easy, because there must be tie beams... to withstand the thrust of the roof. ...Where low stone walls are used... the strength of the walls is sufficient to withstand the thrust...
