22 BULLETIN 1005, IT. S. DEPAETMEXT OF AGRICrLTURE. 
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 suhject to additions and removals of soil material due 
to erosion. It is chiefly forested, although small areas extend into 
tilled fields. 
Suffolli 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 smaU 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 sinnmer 
crop areas. Some areas of crops which had beeii 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.
