Oak panelling, like everything else, passed through various periods and styles. In Queen Elizabeth's time the panels were carried to within about two feet of the cornice; then, after some years, there came a division into lower and upper panelling, the upper beginning at about the height of the back of a chair from the floor. Pictures became more common, and they were frequently let into the upper panelling, and then it was discarded altogether, only the lower half or dado being retained. This, too, after some years, became old-fashioned, and the board known as skirting, or base-board, was all that was left of the handsome sheathing which extended from the floor almost to the ceiling. This old oak panelling was entirely without polish or varnish of any kind, and grew with years and dust almost black in colour. Sometimes it was inlaid with other woods, and often it was made for the rooms where it was placed. Where the panels are carved, they are generally bought in that state and set in plain framework by the household joiner. If, however, the frame is carved and the panels plain, they were made to suit the taste and purse of the owner of the mansion. Oak panelling took the place of the arras, tapestry hangings, and crude woodwork of earlier times. Of course it was adopted by the rich and luxurious, for it rendered more air-tight the draughty buildings. [Illustration: Figure 1. OLD OAK BEDSTEAD.] The oldest furniture was made of oak, more or less carved, whether of Spanish, Italian, Dutch, or English make. The multiplication of objects which we consider necessary as "furnishings" were pleasingly absent, and chests used as receptacles for clothes or linens, for seats by day and beds by night, with a few beds also of carved oak, and tables, made up the chief articles of domestic use. Even the very word "furniture" itself is of obscure origin and was used formerly, as now, to describe the fittings of houses, churches, and other buildings. There are a few terms applied to furniture referring either to its decoration or process of manufacture with which it is well to become acquainted. They are given here in the order of their importance.
