Irregular beds or lenses of loam, sand, or locally developed throughout the formation. Usually the Brandywineis capped by a deposit of loam varying from a few inches to 10 feet ormore, and with an average thickness of about 5 feet. Along the Piedmontborder this loam contains considerable iron and has a decided orangecolor, but in southern Maryland changes to a buff or yellow. 1 Amer. Jour. Sci. (iv), vol. xl, 1915, p. 499.
