the immediate surface, and brownish gray beneath. In many places 
the surface soil is quite mucky. Over much of the type the clay 
comes to 1 the surface, and even where present the sandy mantle is so 
shallow that when plowed enough clay would be 'brought up to make 
the land a clayey soil. The subsoil consists of a heavy clay, stiff, 
close-structured, more or less plastic, and of a “gumbo” or sticky 
character, even where sandy. It also has a somewhat greasy feel. 
The color is usually bluish drab, mottled with streaks of different 
shades of yellow and brown and to some extent with red. Usually 
the mottling increases with depth and the red becomes more conspic¬ 
uous, but the drab color predominates throughout. 
Only one area of this type was mapped. This is found northeast 
of Silver Springs on a low hammock extending out of the area on 
the northern boundary. It is low and flat and in large part semi- 
swampy, and during wet spells it is likely to be covered for some time 
with standing water. Owing to its heavy vegetation and the close 
structure and low-lying position of the subsoil it drains slowly. The 
tree growth is large, consisting of live oak, water oak, white oak, 
and possibly other varieties of oak, hickory, magnolia, cabbage pal¬ 
metto, and some other trees, including a scattering of longleaf and 
shortleaf pines. Depressed areas support some cypress. The large 
cabbage palmetto is particularly conspicuous in this forest growth. 
Bro'om sedge makes a heavy growth, as do some other grasses and 
sedges. 
The soil is residual, but the exact character of the parent rocks 
could not be ascertained. It is probable that the material is from 
rotten limestone and sandstone or arenaceous limestone. 
None of this soil type is cleared. In its present undrained condi¬ 
tion its value lies mainly in its forest growth, which at present is 
being removed and used by veneering mills in the manufacture of 
shipping crates. It also forms good range land for stock, especially 
hogs, because of the large quantity of mast from the oaks. 
In order that this land may be cultivated it will be necessary to 
drain it thoroughly, and whether this can be done economically is a 
question for decision by a competent engineer. If drained, it would 
no doubt be a strong, productive soil. Cabbage, oats, and grass crops 
should succeed. On a closely related soil with a somewhat deeper 
sandy mantle Johnson grass makes large yields. Owing to its heavy 
tree growth, the type is difficult and expensive to clear. In its pres-
