These metal signs were distributed to farmers who participated in the Soil Erosion Service (SES) projects. The SES was founded mainly through Hugh Hammond Bennett's efforts and was the precursor to the Soil Conservation Service (SCS). The SCS supervised 500 Civilian Conservation Corps (CCC) camps between 1933 and 1942. The CCC provided labor and instruction to cooperators. Cooperators were taught the most effective methods to help prevent soil erosion on their farms. | Source: "Kansas Conservation History: 1930-33," United States Department of Agriculture: National Resources Conservation Service Kansas, accessed March 4, 2015, http://www.nrcs.usda.gov/wps/portal/nrcs/detail/ks/about/?cid=nrcs142p2_033461.Download Original File
