Norfolk Series. 
The Norfolk soils are characterized by the light-gray to grayish- 
yellow color of the surface soils, and by the yellow color and friable 
structure of the subsoils. They occupy nearly level to rolling up¬ 
lands throughout the Atlantic and Gulf Coastal Plain, and have been 
derived from unconsolidated Coastal Plain deposits. 
NORFOLK FINE SAND. 
The Norfolk fine sand consists of gray or brownish-gray fine 
sand, 6 to< 8 inches deep, underlain by a yellow or pale-yellow fine 
sand of rather loose texture. The grayish color of the surface soil 
is due to the presence of organic matter, which is present in suffi¬ 
cient quantity to make it more loamy in texture than the subsoil. 
The Norfolk fine sand is found principally in the western half 
of the county. It is also well developed in the vicinity of Green 
Springs and St. Petersburg. 
The surface ranges from nearly level or gently undulating to 
rolling. The land is thoroughly drained, but the texture of the soil 
is fine enough to make it retentive of moisture and crops are affected 
but little by ordinary periods of drought. 
This is the most important and highest priced soil in Pinellas 
County. It is especially well adapted and extensively used for grow¬ 
ing oranges and grapefruit. It is also well adapted to the production 
of truck crops, such as Irish potatoes, sweet potatoes, English peas, 
radishes, onions, lettuce, snap beans, peppers, eggplant, tomatoes,
