The firm of Morrison, McClendon and Tingle had built a mill about two miles north of Sacul after the coming of the Texas & New Orleans to the area. It initially sent its rough lumber to Caruthers Lumber for planing. It moved to the Caro area by 1908, where it had established a planing mill in 1906.
The firm had dropped Tingle by 1906. That year, it was selling planed lumber from its planing mill at Dalmont to Southern Mills Company. Morrison and McClendon sold the planing mill to Southern Mills Company in September, 1906. The company in 1908 gave a deed of trust to Cushing Land & Timber Co of T. J. Williams on a sawmill, lumber, yards on the Whiteman-Decker Lumber Railroad, a sawmill, an edger, boiler, engines, and timber located west and south of the mill tract near the lumber railroad.
When Southern Mills Company closed out its interests in Nacogdoches County in 1908 and 1909, the Dalmont operation closed as well.
