closely those of the more nearly level areas of the Norfolk fine sand. 
The topography is nearly level to undulating. This type is much 
more retentive of moisture than the Norfolk fine sand. 
The natural vegetation consists mainly of a heavy growth of long- 
leaf pine, with scattered water oak, blackjack oak, and live oak on 
the more sandy phases. Wire grass grows luxuriantly. 
The soil is naturally well supplied with humus, which accounts 
for the dark color of the immediate surface of forested areas. By 
continuous cultivation the content of vegetable matter is diminished, 
and the. soil loses its dark color and loamy feel unless additional 
vegetable matter is supplied. There is a general need over this type 
for the practice of systematic crop rotation and for the application of 
large quantities of stable manure or the plowing under of occasional 
green crops, such as cowpeas, velvet beans, or beggarweed, in order 
to maintain the supply of humus in the soil. 
Most of the type is under cultivation. It is considered one of the 
strongest soils in the county for general farm crops. Corn and cot¬ 
ton do well without heavy applications of commercial fertilizer. 
Corn averages about 18 bushels per acre, though some farmers secure 
much larger yields. Cotton ordinarily produces from, one-fifth to 
one-third bale per acre. Cowpeas and velvet beans do well. Pea¬ 
nuts are frequently planted in the corn rows and fed to stock after 
the corn has been harvested. Oats and rye are grown for forage 
and are cut just before the grain ripens. The soil is well adapted to 
millet, which has lately been introduced. Sweet potatoes and Irish 
potatoes both produce good yields. Sugar cane, strawberries, pecans, 
Scuppernong grapes, and bramble fruits also succeed on the type. 
Though the Norfolk fine sandy loam is not quite so early in ma¬ 
turing vegetables as the Norfolk fine sand, it is used extensively in 
other localities for trucking with good results. Cigar-wrapper to¬ 
bacco has been grown successfully under shade on this type in other 
sections of Florida. 
The Norfolk fine sandy loam is held at about the same prices as 
the Norfolk fine sand. 
Leon Series. 
The Leon series comprises the loose, light-gray to white sandy 
soils of the south Atlantic and east Gulf coast flatwoods region, 
which in their typical development have a hardpan stratum usually 
at a depth of 12 to 24 inches. This stratum ranges from 8 to 10 
inches in thickness and consists of a compact layer of fine sand or
