Anotations

Scope note:

Wood in the form of large, squared or dressed pieces used for forming part of a built work or used to create a curving frame branching outward from the keel of a ship and bending upward in a vertical direction. Timber that is curved or bent may be a composite formed of several pieces rather than being a single piece of wood.
