Spruce is one of the most important woods in the Eastern United States. It grows on large areas in pure or nearly pure stands, is distributed over many of the Northern States, and extends into the southern Appalachians at the higher altitudes. It is used more than any other wood in the manufacture of paper, and supplies a large amount of lumber and other material. Various methods of forest management for spruce have been adopted by large lumber and pulp companies, of which spruce often forms the principal cut. The chief purpose of this bulletin is to formulate definite systems of forest management for various conditions.
