The Texas Forest Service reported that Williams was installing a Newton County Lumber Company sawmill in Newton County in 1945 that would cut 75,000 feet daily. He would be using lands purchased from Wier Long Leaf Lumber Company. The newspaper must have been in error because a Newton County Lumber Company was already cutting lumber at Newton by 1944. A reasonable assumption is that both mills, the one at Newton and the one above at Mauriceville, were owned by Buck Williams and the different company names were used interchangeably.
This mill burned at least two times. The Texla Lumber Company sawmill at Mauriceville cut 9,093,000 board feet during 1960. It produced 9.6 million board feet in 1973. The Williams family owned the Williams and Sons Lumber Company in Garrison in the 1930s and 1940s.
