and the small quantity of organic matter present tend to make the 
drainage excessive, and even under ordinary conditions crops suffer 
for lack of moisture. With irrigation and liberal applications of 
commercial fertilizers a great variety of vegetables common to the 
region can be grown, though only by very intensive 'methods can 
success be attained in the cultivation of the type. . 
Coxville Series. 
The Coxville series comprises dark-gray to 1 nearly black soils. The 
subsoils range from a moderately mellow, friable clay in the upper 
portion to yellowish, rather plastic, compact clay mottled with drab 
and light red in the lower portion. The topography is prevailingly 
flat, with frequent sparsely forested areas. The treeless lands are 
found in the savannas of the seaward portion of the Atlantic Coastal 
Plain. The flat surface induces poor drainage. The soils are used 
for the production of cotton, corn, and oats. In the Carolinas straw¬ 
berries are grown with profit. When well drained the types are some¬ 
what more productive than the Norfolk soils. The series has been 
mapped mainly in North Carolina, South Carolina, and Georgia. 
Only one type in the series is found in Bradford County, and the area 
of this type is but little more than 3 square miles. 
COXVILLE FINE SANDY LOAM. 
The surface soil of the Coxville fine sandy loam consists of gray 
to dark-gray or nearly black fine sand containing a high percentage 
of organic matter. At an average depth of about 8 inches the mate¬ 
rial passes abruptly into a very pale yellow fine sand, which in the less 
thoroughly drained areas is almost white or light gray. At about 18 
inches a more distinctly yellow loamy fine sand, which is unevenly 
mottled with drab and gray, is encountered. With increasing depth 
the mottlings become more pronounced and the texture heavier, un¬ 
til at about 28 inches a friable fine sandy clay or heavy fine sandy 
loam, having a complexly mottled yellow, drab, red, and brown color, 
is encountered. In the lower part of the 3-foot section the subsoil is 
decidedly heavy and in places is a plastic clay. 
The Coxville fine sandy loam in Bradford County is not typically 
developed. It was only separated from the Portsmouth fine sandy 
loam because of its slightly better drainage and its mottled subsoil. 
The color of the surface soil departs from the typical gray in places, 
becoming brown or grayish brown. The type also varies consider-
