252 SELECTION OF FURNITURE Oak. There are two general groups of oak woods, the red and the white. This wood is rather heavy, hard, and tough, but it is easily worked with tools; the grain is interesting though rather coarse. Quarter-sawed oaks are popular because of their grain. Quarter-sawing is cutting a log into quarters and then into boards by cutting alternately from each face of the quarter—a more costly process producing more beautiful grain than ordinary cutting. There was also an ugly period in oak, the recent golden oak era, that made oak disliked by people of taste. At the present time, oak is returning to favor as it is used in the modern and also in early English, Spanish, and French provincial styles. Mbst oak pieces are rather large, solid, and masculine in effect. Maple. There are two principal varieties, hard and soft maple, with the Oregon maple about halfway between the two. Hard maple is best for furniture because of its great strength, its hard, smooth surface, and fine, light reddish brown color. The grain is usually straight, although veneers of curly and bird's-eye maple are prized. Maple is one of our choicest furniture woods, suitable for dining rooms, bedrooms, and living rooms. It is commonly used for reproduction of early colonial furniture. In addition Maple is sometimes utilized for commonplace furniture and also for frames, drawers, and stretchers of other furniture where strength is very important. Gum. Red gum is the name of the tree and also of the heart- wood of the tree, which varies from rich reddish brown to dark chocolate-brown in color. Sap gum is the name of the sapwood of the same tree; it is light pinkish. Boards showing both heart- wood and sapwood are striking in color and value variations. Gum is a recent addition to the furniture woods, as its use has been made possible by modern methods of seasoning wood. For- merly it became twisted while drying. Now it is one of our most important hardwoods although it splits and becomes dented rather easily. It has a pleasing grain and color and takes finish so well that it is often stained to imitate other woods. It is used for the less important parts of mahogany pieces, posts and rails being made of red gum and the veneered panels of mahogany. Furniture manufacturers consider that this substitution is perfectly legiti- mate provided the piece is not sold as all mahogany.
