Morrison, Bare and Cass erected the paper and pulp mill in Tyrone in 1878. The West Virginia Pulp and Paper Co. consolidated with it in 1899. The major part of the mill ceased operations in 1970. Since 1970, the main product was the American Eagle line of paper, made of 50 percent recycled paper. The high-quality paper, noted for its excellent printability, runability, and reliability, was used by the National Geographic Society for its magazine covers. 
    Historic structures surviving from the 19th century are: two powerhouses used to generate electricity and steam for the mill, the carpenter’s shop and blacksmith’s shop, and a long, two-story building along Pennsylvania Ave. 
    WestVaco ceased operations and closed in October 2001. In July 2003, Team Ten LLC announced the purchase agreement with the Mead WestVaco Company and resumed operations in November 2003 as the American Eagle Paper Mill.
