The mill of the Bonwier Lumber Company at Bonwier appeared in the January 1907 published records of the Lumbermen's Credit Association (LCA). No mill at Bonwier appeared in the published records of the LCA for January 1905. It is possible that the mill was also known as the Long Leaf Lumber Company and may have been a contract mill of the Texas and Louisiana Lumber Company. The mill was built about 1905 as a circular saw sawmill capable of cutting 45,000 board feet per day. It was announced in the Southern Industrial and Lumber Review in December 1908 that plans were being made to tear down this mill in order to erect a larger 80,000 feet mill on the site. Its speciality of sawn timbers required a larger circular saw, rather than a band, and the company had ordered the equipment and additional machinery. The new cutting capacity was expected to be used within a month.
Southern Lumberman reported in July 1908 that the West Lumber Company had gained control of the mill.
