214 FLORIDA GEOLOGICAL SURVEY-SEVENTH ANNUAL REPORT. 
according to the relative rate of growth of the trees, and this class of 
land conies in as third rate, although some of the better parts will 
grade as second rate. The more loamy areas support the growth 
spoken of as open pine woods, in which there is no undergrowth and 
blackjack does not come in to any important extent. The flatter 
or low-lying undulating areas, because of nearness to the water table, 
also support some post oak, water oak, and turkey oak. Where the 
turkey oak grows the land is considered of better quality. Such 
areas are found from Santos south along the Seaboard Air Line 
Railway. 
As previously mentioned, there are two other phases of this type, 
the hammock and the scrub areas. The former supports large trees 
of water oak and live oak, magnolia, hickory, cabbage palmetto, and 
some others. This growth is influenced by the better moisture condi¬ 
tions, the roots being able to reach the permanent water table. The 
scrub areas are characterized by a stunted growth of evergreen oaks 
and spruce pine. These areas are sharply separated from those of 
the rolling lands with pine and blackjack growth. There is appar¬ 
ently no difference in the soil to the depths examined, and no con¬ 
clusive explanation for one growth taking hold to the exclusion of 
another can be given here. It was noticed, however, that the subsoil 
in the scrub areas was generally more moist, and this may account 
for the difference in the vegetation. There was no topographic 
change, the growth covering- the higher as well as the lower situa¬ 
tions. These areas of scrub are regarded as very poor and no at¬ 
tempt is made to cultivate them. There is no wire-grass growth in 
the scrub areas, but on the rest of the type there is a good wire- 
grass sod that early in the season affords fair pasturage for cattle, 
contributing somewhat to the value of the land. 
The main value of the type has been its growth of longleaf pine, 
which usually is first worked for turpentine during a period of years 
and then cut and sawed into lumber. With the trees removed the 
greater part of this type has little value and is not usually desired 
for farming. The population,over this type is sparse and-many sec¬ 
tions are occupied solely by negroes. 
Some development is taking place on the better areas of the Nor¬ 
folk sand near railroads, but there is not a wide range of crops pro¬ 
duced. Naturally the type is one of low productive value. Fertiliza¬ 
tion is necessary to produce anything approaching good yields. The 
soil will make a small yield of corn—about io bushels to the acre.
