This soil occurs chiefly on the steeper slopes from the upland to 

 water level and around the stream heads. It consists largely of 

 coarse sandy wash from upland types. Drainage is excessive and 

 the material is subject to additions and removals of soil material due 

 to erosion. It is chiefly forested, although small areas extend into 

 tilled fields. 



Suffolk gravelly loam. — The surface soil of the Suffolk gravelly 

 loam is a grayish-brown gravelly loam, with a depth of 8 inches. 

 This is underlain by a pale-gray gravelly loam to 36 inches or more. 

 The deeper subsoil is usually saturated. 



The type occurs in level or depressed areas where natural drainage 

 is poor. A large part is in forest and the remainder is farmed to 

 various crops, chiefly by colored farmers. 



Suffolk loam. — The Suffolk loam consists of 4 or 5 inches of dark 

 gray loam, underlain by a subsoil of gray silty loam, which extends 

 to a depth of 36 inches. A small amount of fine gravel is found in the 

 soil and subsoil. The deeper subsoil is usually saturated. The type 

 occupies depressed areas and is poorly drained. It is chiefly in forest. 



Swamp. — A few small areas of Swamp occur around the margin of 

 the Diamond Springs area. These lie at water level and are not 

 easily drained. 



It is apparent that a considerable diversity of soil texture and of 

 natural conditions of drainage exists within the Diamond Springs 

 area. The three soils of the Sassafras series and the Norfolk coarse 

 sandy loam are well drained. The Norfolk silt loam, loam, and 

 gravelly loam are but moderately drained. The Suffolk loam and 

 gravelly loam are poorly drained. These facts become evident in 

 the crop uses of the different soil types. 



USES OF SOILS. 



The completed soil and crop maps for November, 1915, and for 

 June, 1916, were measured in order to show the relative and absolute 

 uses of each soil for the production of the different crops and groups 

 of crops. The areas given for November represent the fall and winter 

 conditions; those for June represent the spring and early summer 

 crop areas. Some areas of crops which had been marketed in the early 

 spring are not shown. 



Tables IV and V give the statistics in detail, the former showing 

 conditions in June and the latter in November.
