Photograph of a scene on the Marion Bryant farm.

Photograph of cotton rows growing on the contour on the side of the hill, while alfalfa grows at the bottom of the slope on the Marion Bryant Farm. The back of the photograph proclaims, “The cotton rows are on the contour on the side of the hill, while the alfalfa is at the bottom of the slope. In former years when the cotton was farmed in straight rows up the slope, there was a great deal of washing in the sandy soil of the cotton field and the silt was deposited in the alfalfa, threatening to destroy it. The cotton field was then contoured and since then there has been no damage to the alfalfa below.”
