 feet above water-level; common and reaching its greatest development in the south Atlantic states. 



Wood very heavy, hard, strong, tough, very close-grained, compact, difficult to work, susceptible of a beautiful 



polish; layers of annual growth obscure, often hardly distinguishable, containing many small open ducts arranged 



in short broken rows parallel to the broad, conspicuous medullary rays; color, light brown or yellow, the sap-wood
