From the red color of the Cecil soils it would seem that the rocks from which they are derived contain a higher percentage of the iron-bearing minerals than those giving the Durham, and the oxidation of this iron gives it the intense red color. The diorites are dark green heavy rocks, locally called "nigger head" rocks, and occur throughout the granite and gneiss formations. The Iredell soils have been derived from the weathering of this diorite. They consist of gray to brown soils and have yellowish or bro-wnish- yellow, waxy, putty-like, clay subsoils. Like the Mecklenburg soils, the yelloAvish-green, soft diorite rock is generally found at 18 to 36 inches below the surface. Along most of the streams throughout the county are developed nar- row strips of bottom-land or alluvial soils. These soils represent ma- terials washed from the uplandsâthat is, the cream of the uplandsâ and deposited by overflow water upon the flood plains. The heavy ma- terial is a brown to reddish-brown color, and where having a uniform texture has been classed as Congaree silty clay loam. The material in the bottom-lands is mixed up in texture and the soils have a lower agri- cultural value due to lack of drainage.
