Photograph of Guiglardi examining some alfalfa on his irrigated farm where new borders have been established according to plans made with the assistance of the Soil Conservation Service technician assigned to the district. The back of the photograph proclaims, "Photograph of Mr. Guiglardi examines some of the alfalfa on his irrigated farm where new borders have been established according to plans made with the assistance of the Soil Conservation Service technician assigned to the district. Note the contrast between the irrigated valley land in the foreground and the sand hills in the far background. Flood waters from these sand hills frequently do serious damage to the fertile productive valley lands. In 1941, a flood from the sand hills severely damaged an 8-acre field on this farm. Four acres were deeply sanded and four additional acres were damaged severely. With the assistance of the Soil Conservation Service, owner leveled the land, changed the rows, and in 1942 produced an average of two bales of cotton to the acre. It was the best production he had ever made on the 8 acres. Without this work, the land would have produced nothing in 1942."
