2. Red oak woods about iy 2 miles E. S. E. of Ocala, 9 inches 
deep, taken at a place where the trees were all deciduous (figure 
65) . 
3. Sandy hammock about six miles south of Ocala (“Leon 
sand”), 8 inches deep. Vegetation nearly all evergreen (figure 
66 ) . 
4. Somewhat calcareous hammock about one mile southeast 
of Ocala, 8 inches deep. Vegetation about like that of No. 1 (figure 
67)* 
5. Very calcareous high hammock about 23/2 miles south of 
Ocala. A black loam with many fragments of soft white limestone, 
taken to a depth of 6 inches. Trees in the immediate vicinity nearly 
all deciduous, including Quercus Schneckii, Acer Floridanmn, etc.

MECHANICAL ANALYSES OF THE SOILS. 
The following mechanical analyses of soils from the Ocala area 
(all from the hammock belt) have been extracted from Bulletin 13 
of the Division of Soils of the U. S. Department of Agriculture. 
(A preliminary report on the soils of Florida, by Milton Whitney, 
1898). The localities and depth of the samples are as follows: 
1. Light hammock near Ocala. Depth 0-9 inches. 
2. Subsoil of same. 9-24 inches. 
3. Lower subsoil of same. 24-36 inches.
