History by Gil Hoffman: (Mississippi Rails website)
The Leaf Lumber & Veneer Works was incorporated at Leaf, Greene County on April 14, 1924, by B. E. Green, of McLain; J. C. Daughdrill, of Leaf, and H. M. Hempstead, of Mobile, AL, with authorized capital stock of $100,000. In early 1924 the company purchased the plant of the Overstreet Veneer Company, at Beaumont, Perry County, and moved it to Avent, adding a bandsaw, edger and trimmer. The Avent mill, with a cutting capacity of 25,000 feet per day, cut hardwood and cypress.
In April 1929 the company bought the plant and timber holdings of the Southern Saw Mill Company, at Greenville, Florida, and moved its operations from Avent, MS, to Greenville, FL, with operations commencing there in July 1929.
