be maintained. The sand has not been drained and reclaimed to any 
extent for agricultural purposes. 
Chesterfield series. — The soils are generally gray in color, with 
friable yellow subsoils. The series represents soils having a thin 
layer of Coastal Plains material (Norfolk) overlying residual Pied- 
mont material (mainly Durham). The members are developed near 
the junction of the Coastal Plain and Piedmont, or where there is an 
overlapping of sedimentary upon residual material. They are 
adapted to the general farm crops of the region, principally corn, 
oats, forage crops, and cotton. 
The sandy loam occupies a fairly large area along the borders of 
the Coastal and Piedmont boundary, and is used principally for the 
production of corn, wheat, oats, and tobacco. It is also adapted to 
truck crops, peaches, and small fruits for local markets. The grav- 
elly sandy loam is used to a very limited extent for farming pur- 
poses. It should be devoted to pasture and orchard fruits. 
Bradley series. — The surface soils are grayish and sandy. The 
subsoils are predominantly red, in places slightly mottled with yel- 
low or gray, of clay texture. The series represents soils having a 
thin surface mantle of Coastal Plains material (Norfolk) and residual 
Piedmont material (mainly Cecil). These soils are developed most 
extensively near the junction of the Coastal Plains and Piedmont, 
or in that region where there is an overlapping of sedimentary mate- 
rial made up of reworked Piedmont-Appalachian upon residual 
Piedmont material. They are adapted to the general farm crops of 
that region, principally corn, oats, forage crops, and, in the southern 
part of the State, cotton. Only the sandy loam has been encountered 
so far in the State, and this is not so productive as the Cecil sandy 
loam. 
Leonardtown series. — The soils of this series are gray to pale- 
yellow in color. The subsoils are mottled gray, yellow, and red and 
ordinarily carry clay lenses and pockets of sand. These soils occupy 
gently rolling to rolling country in the Chesapeake Bay region of 
the Coastal Plains, where the Glacial-Piedmont- Appalachian material 
has been deposited. They are best suited to the general farm crops. 
The loam, which is the only type so far encountered in the State, 
has only in a few instances been handled to show its capabilities. 
The poor natural drainage of this type has retarded its development. 
When properly prepared it is suited for pasturage, corn, grass, and 
late truck. 
Sassafras series. — These soils are distinguished by their yellowish- 
brown to brown color and mellow structure. The subsoils are red- 
dish-yellow and friable in structure, resting upon coarser material or 
beds of gravel and sand at depths varying from 2^ to 5 feet. The 
series is of sedimentary origin, the material from which it has been
