This plant was producing 15,000 feet daily in 1906. The Southern Industrial and Lumber Review reported in 1908 that the Magnolia Lumber Company, located at the intersection of Harrisburg-Houston road and Green's Bayou at Harrisburg, was owned by W. J. Athens and T. D Warley of Houston. The mill operated on the banks of Green's Bayou with logs being drawn from the water by a bull chain. The sawmill and planing mill were under the same roof. Equipment included a circular saw, trimmer, edger, and two planers. Two Stevens dry kilns of brick and steel, heated by furnace underneath rather than steam, and dried lumber in eighteen hours. Logging was by bayou and by rail. The mill was built four years earlier.
