Butternut is really a branch of the family of walnuts, and differs from them only slightly. The wood is used to some extent for inside finish, and is cheaper than most of the other hard woods. It is light, but not strong, and is fairly soft. In color it is light brown. The trees, of medium size, are found in the eastern states from Maine to Georgia.
