Soil Erosion in the Mississippi Valley

Although this article discusses erosion mainly from the angle of farming, it gives the fundamentals of its process so clearly that the article is reproduced here in full. It is accepted that erosion in the aggregate is far more serious on farm lands than on forest lands, and that the loss of our surface soils is one of cataclysmic proportions. The national character of the problem, and the close connection between farm-soil conservation and river control are particularly stressed, calling for an attack by engineers, foresters and farmers under united leadership.
