Miller-Brooks Manufacturing Co built its mill in Jacksonville on Alabama Avenue, next to the tracks of the Southern Pacific and Missouri Pacific. B. J. Albritton served as President. It included a planing mill. Shavings and refuse from the saw and planing mills were blown to the Jacksonville Ice & Electric Company for boiler fuel, which in turn generated electricity for the sawmill and private consumers. The Jacksonville Light & Power Co was located on the corner of Neches and South Front Street, immediately south of the International & Great Northern railroad.
Sam A. Cobb, Sr., leased the mill in 1912 and bought it in 1916. In 1917, Wade W. Holman became Cobb's partner and the company operated as Cobb-Holman Lumber. The company had logging fronts at Fry's Switch, Hume's Switch, Price's Switch, Overton, and Tecula. It contracted the cut of several smaller sawmills over the years, shipping their rough lumber to Jacksonville for dressing on the Cobb-Holman planers. The plant also included trimmers, edgers, a planing mill, dry kilns, and ran a commissary. It was listed in the 1928 edition of the Southern Lumberman's Directory of American Saw Mills and Planing Mills with a daily capacity of 30,000 feet on its circular saw. The mill continued for some years to supply the electric light company with boiler fuel. The demand from the East Texas oil fields supported the mill during the 1930s. When Cobb died in 1943, ownership devolved on the Wade W. Holman family. The company produced one million board feet of lumber during 1960. By the 1970s, the company was manufacturing trailer homes. The company closed in 1987.
