MINOR SPECIES OF NATIVE WOODS A few of the numerous other native woods used to a small extent include the following : Ailanthus, mountain ash, and silver bell, for boxes and crates; blue beech, catalpa, and china tree, for vehicle parts; catalpa, china tree, kalmia, haw, mesquite, mulberry, and sumac, for furniture ; manzanita, mountain lilac, mountain mahogany, and orange, for novelties; mulberry, silver bell, and witch-hazel, for millwork.
Since there are more than 500 tree species in the United States, it is obvious that, so far as numbers are concerned, only a few of them are mentioned in the foregoing pages. No species, however, has been omitted which is a considerable source of lumber supply or of much importance in general commerce. Many of the unmentioned woods are used in a small or local way for a large number of purposes, among which are novelties, turnery, etc.
