Photograph of severe gully erosion.

Photograph of erosion caused by unprotected farmer terrace outlets and road ditch run-off. Field on the left has been terraced for 8 to 10 years. Terraces had too much fall. Roadside ditch will be sloped and added with Bermuda grass. Road graded and field on left will be terraced to conform with standard grade and land slope as recommended by SCS. OK-8087

Photograph of an UNIDENTIFED man with horse drawn equipment mowing weeds in a native bluestem meadow to promote of grasses. The back of the photograph proclaims, "Mowing Weeds In Native Bluestem Meadow to promote growth of grasses. Area is protected from fire and grazing and is mowed regularly for weed control. Coop. has good demand for hay because meadow is kept free of weeds, and says "I have a steady demand for clipped hay at 35₵ but demand is light. My mowed meadows produces ¾ T. more per A. than my unmowed fields." San Saba soil 2 1/3% slope."

Photograph of African lovegrass sown in March 1940 and planted in rows on land retired to pasture. A house and windmill sit dead center in the background of the photograph. The back of the photograph proclaims, "African Love Grass in rows on land retired to pasture. Very sandy land. Sown in March 1940 at rate of 5# per acre Stevensville soil, 2% slope."

Photograph of a "Windbreak and post lot consisting of Chinese elm and catalpa trees. Trees were set out about 1937." A building and car sit just to the right of the windbreak and post lot.

Photograph of a constructed drop inlet constructed where an unsafe bridge used to stand to stabilize erosion from gully. The back of the photograph proclaims, "Highway Erosion Control. Unsafe bridge eliminated and drop inlet constructed, (Highway Commission, WPA, and SCS cooperation) to allow deep gully to silt in, thus stabilizing erosion. Stock will also be watered here as water gathers in basin."

Photograph of masonry drop structure for gully control, terrace outlet channel. Masonry structure was built in later 1937 in natural wash, badly gullied, to accelerate silting for erosion stabilization. Outlet channel on the right is now well-vegetated, providing a safe waterway and the former active erosion behind the structure is almost 100% stabilized. OK-5969-B.

Photograph of a retired field with severe washing causing a small gully to form. A dirt road is on the left of the photo and several buildings are in the background. The back of the photograph proclaims, "Gully control with small earthen dams. Small gullied area retired from cultivation because of severe washing. Small dams have Bermuda roots mixed in to promote vegetative cover. Vernon F. S. L."

Photograph of masonary arch drop, gully control terrace outlet channel. Masonry structure was built latter part of 1937 in natural wash, badly gullied to accelerate silting for erosion stabilization. Outlet channel on right is now well vegetated, providing safe watersay and former active erosion behind structure is almost 100%.

Photograph of a follow-up picture of Okla-5969 of the progression of a Masonry arch drop in stabilizing gully erosion. The back of the photograph proclaims, “Masonry Arch Drop, Gully Control Terrace Outlet Channel. Masonry structure was built latter part of 1937 in natural wash, badly gullied, to accelerate silting for erosion stabilization. Outlet channel on right is now well vegetated, providing safe waterway and former active erosion hehand [sic] structure is almost 100% stabilized.” Both men in this picture are UNIDENTIFED.

Photograph of strips of native grass consisting of Blue grama and little bluestem on contour. A house sits in both the immediate and distant background of this photograph. The back of this photograph proclaims, “Strips of Native Grass on Contour Blue gramma [sic] and Little bluestem. Area on left retired from cultivation and grass becoming established. Cultivation continues between strips to provide income from land while grass becomes established. Strips planted spring of ’37 at rate of 30# to A after preparation of seed bed. Vernon F. S. L. 3 to 4% slope.”
