NORFOLK FINE SAND. 
The Norfolk fine sand consists of a gray or pale yellowish gray 
to dark-gray, rather loose, incoherent fine sand, underlain at about 
5 to 8 inches by a yellow, pale-yellow, or grayish-yellow fine sand, 
extending to a depth of more than 3 feet. Like the surface soil, the 
subsoil is decidedly incoherent and the texture is often modified by 
the presence of larger particles, which occasionally attain the size of 
buckshot or small peas. 
Variations from the typical soil are encountered where the type 
grades into other soils. Where the Norfolk fine sand passes into the 
Portsmouth fine sand the surface soil becomes darker in color be¬ 
cause of the larger humus content, and the subsoil in its upper part 
is a dingy or dull yellowish-gray, appearing as though the hardpan 
layer found in the Leon soils at one time might have been present. 
The lower subsoil in such situations is grayish yellow or pale yellow. 
Where the Norfolk fine sand grades into'the Leon fine sand the 
surface soil of the former is grayish white, the subsoil having the 
dingy yellowish-gray color shown where it approaches the Ports¬ 
mouth fine sand. In other areas the subsoil may incline more toward 
a whitish gray than is typical. 
The surface soil of the Norfolk fine sand differs from that of 
the Portsmouth fine sand in that its organic-matter content is de¬ 
cidedly smaller, which causes the color to be lighter. The subsoil of 
the Norfolk fine sand is yellow, while that of the Portsmouth fine 
sand is white and usually includes a hardpan layer. The Norfolk 
fine sand occupies higher situations and is well drained. The chief 
difference between the Norfolk fine sand and the Leon fine sand is 
the white or very light color and the occurrence of a hardpan layer 
in the subsoil of the latter. 
In extent the Norfolk fine sand is exceeded in Bradford County 
only by the Portsmouth fine sand and fine sandy loam. It occurs in 
almost all parts of the county, though its most general development 
is along the Clay County line southeast of Hampton, in the lime¬ 
stone sink region in the southwest corner of the county, and along 
the valley of Olustee Creek in the western part. 
The topography of the Norfolk fine sand usually varies from 
almost level to undulating*. The more nearly level areas are usually 
darker at the surface, owing to the accumulation of organic matter. 
In all cases the drainage is adequate and in the more rolling areas 
it is even excessive. In the southwestern part of the county the to-
