This picture was taken in 1940, and shows a farmer turning up his pinto bean field. I love the scene because the farmer is plowing with two horses. I believe they are horses; they might be mules. I wonder what productivity boost farmers got when tractors came along. You would have to be able to plow much more land with a tractor that with horses, but I don't really know what the improvement factor was.
