Moorer and Carter, according to Dr. William Woldert, who was raised in Tyler from the age of four in 1849, had a sawmill about three miles southwest of Mt. Sylvan. According to Dr. Woldert, the mill opened about 1870. Equipment included a planing mill. This may be the sawmill that Albert Woldert later wrote about being the center and focus of a small community named “Mechanicsville.”
Gregg County records note that Christopher B. Carter and W. J. Moore had a sawmill partnership. A bill of sale for $3,500 from Carter to Moore in 1875 recorded that the mill was located near Camp's Ferry on the Sabine River. Property included lands, steam mills for lumber and cornmeal, two log carts, two log wagons, three road wagons, and eleven oxen.
Dr. Woldert writes that first the sawmill, then a furniture factory, and finally a dozen houses were constructed about four miles east of the Neches River and two and a half miles southwest of Mt Sylvan. The community existed until about 1875, when it was destroyed by a forest fire.
