This collection (1917-1949, undated) contains photographs and educational artwork relating to soil conservation work. The bulk of the collection consists of the 212 negatives and 309 prints, taken in the 1930s and 1940s. They are arranged by the subject numbers originally assigned to them, and by project and date within each subject. Case Farm Equipment is used throughout. There is also educational art work explaining conservation practices and how soil conservation works. Some of the educational materials are photographs and others are drawings or reproductions of a machine or natural process, such as erosion, showing how the machine or process works.



The collection was originally part of the Hugh H. Bennett Papers, a collection that had suffered water damage with subsequent mold development. Some of the photographs and negatives were unusable and were discarded. Some that remain are badly damaged, but still serve to illustrate the soil conservation practice depicted.
