Paneling is one of the most beautiful methods of wall decoration. There are many styles of paneling, stone, marble, stucco, plaster, and wood, and each period has its own distinctive way of using them, and should be the correct type for the style chosen. The paneling of a Tudor room is quite different from a Louis XVI room. In the course of a long period like that of Louis XV the paneling slowly changed its character and the rococo style was followed by the more dignified one that later became the style of Louis XVI. Tapestry and paintings of importance should have panels especially planned for them. If one does not wish to have the paneling cover the entire wall, a wainscot or dado with the wall above it covered with tapestry, silk, painting, or paper, will make a beautiful and appropriate room for many of the different styles of furniture. A wainscot should not be too high; about thirty-six inches is a good height, but should form a background for the chairs, sofas, and tables, placed around the room. A wainscot six or more feet high is not as architecturally correct as a lower one, because a wall is, in a way, like an order in its divisions, and if the base, or wainscot, is too high it does not allow the wall, which corresponds to the column, to have its fair proportion. This feeling is very strong in many apartment houses where small rooms are overburdened by this kind of wainscot, and to make matters worse, the top is used as a plate-rail. A high wainscot should be used only in a large room, and if there are pilasters arranged to connect it with the cornice, and the wall covering is put on in panel effect between, the result is much better than if the wall were left plain, as it seems to give more of a _raison d'être_.
