The breadth of terraces

1560. The breadth of terraces, and their height relatively to the level of the floor of the living-rooms, must depend jointly on the height of the floor of the living-rooms and the surface of the grounds or country to be seen over them. Too broad or too high a terrace will both have the effect of foreshortening a lawn with a declining surface,or of concealing a near valley. The safest mode in doubtful cases is, not to form this appendage till after the principal floor is laid, and then to determine the details of the terrace by trial and correction.
