According to records published about 1925, R. S. Tennir and J. T. Brackenridge built a sawmill at Carmona near the tracks of the Trinity & Sabine. On January 27, 1890, they sold it to William Cameron and Company. The sawmill's capacity was rated at between 40,000 and 60,000 board feet per day. The planing mill was rated at 40,000 feet per day. Cameron records also showed that the sawmill was destroyed by fire on May 16, 1910, but was “immediately rebuilt.” Another fire on July 28, 1914, again destroyed the sawmill, and this time, the mill was not rebuilt. The planer continued to operate until 1915, and logging operations at Carmona were transferred to the Saron facility. The logging operation did, however, continue to use its own logging trams. The American Lumberman, in 1906, noted that the Cameron tram road was eighteen miles long and operated three locomotives and thirty cars, the same numbers given in an article of 1900. Keeling reported that Cameron Lumber Mills operated five narrow gauge geared locomotives over the tram road, which was headquarted at Cameron (Carmona). The Gulf Coast Lumberman reported on 1 August 1914 that a fire had ravaged the mill on 14 July 1914. The plant was not rebuilt and logging trams were directed to the Cameron Lumber Company mill at Saron, Trinity County.
