In 1957, the L & M Lumber Company employed thirty-five employees. The Gulf Coast Lumberman reported in 1958 that the mill was cutting 20,000 feet daily and was installing a pressure treating plant. The sawmill cut 13,545,013 board feet in 1960. In 1966, the mill worked with southern pine and did some wood preserving. The mill employed fifty-five persons in 1973, and cut mostly slash pine.
