After the Civil War, the people of Thompson's Station rebuilt their community, reformed agricultural practice, and entered a new era of economic prosperity. A symbol of social and community rebuilding is the historic African American congregation of Connection Hill Primitive Baptist Church, rooted in 1878, when Samuel A. Pointer sold a lot for $5 for a "Colored Primitive Baptist Church" and for the future welfare and prosperity of the colored race in this section and the education of their children. The present church building on Thompson's Station Road dates to 1956. Rock terracing on the hillside recalls how farmers adopted new agricultural practices after the Great Depression of 1929 to 1938. The terracing dates to the mid-1930s, when President Franklin D. Roosevelt's New Deal called for land conservation and agricultural renewal. The Agricultural Adjustment Act of 1933 addressed low farm prices and overproduction, and the Soil Conservation Act of 1935 established local committees of farmers to decide what was best for their communities. On the land of Preservation Park, the Soil Conservation Service worked with farmers to reduce soil erosion and preserve topsoil by terracing sloped land and discouraging the farming of steep hillsides. By March 1935, farmers in Williamson County had pledged 2,500 acres of farmland to terracing, and experts held terracing demonstrations throughout the county, including at the Lee Ridley farm near Thompson's Station. In the mid-twentieth century, farmers also largely ended their dependence on cotton and turned to more mixed agriculture, with livestock production gaining importance. Williamson County became one of the state's major livestock markets in those decades, a pattern still reflected in the open pastures of Preservation Park. Business leaders such as the Williamson County Banking and Trust Company supported improved agriculture, and in 1935 the University of Tennessee Agricultural Experiment Station recommended Lespedeza sericea for erosion control on poor soils. The Home Demonstration Club at Thompson's Station, founded in 1926 with eighteen members under president Elise Gary, met in the basement of the Thompson's Station school and was committed to better family and rural community life.
