GEOGRAPHY OF CENTRAL FLORIDA 175

 It is characterized by hammock vegetation with evergreen and deciduous trees approximately equal in numbers, as described farther on. A considerable portion of it is under cultivation. Salamanders seem to invade this soil only where it has been cleared and abandoned a short time, perhaps indicating that they do not like shady places.
 Calcareous uplands. Where the soft Ocala limestone crop: out, as near Ocala and in southeastern Citrus County, it grades into a black sticky soil rich in humus. One. such area a little south of Ocala has been mapped as "Fellowship clay loam," and a somewhat similar soil occurs farther north near McIntosh, where no rock outcrops are in evidence, and in and around lime-sinks in the Hernando hammock belt. It is represented by mechanical analyses 15, 16 (perhaps also 17 and IS), 25 and 26, and chemical analyses T and U.
 The vegetation is of the hammock type, with the great majority of the trees deciduous. The hackberry and 'a few other plants of the same or allied families are very characteristic. Although this is a very rich soil, it. is usually too hilly or rocky to be, cultivated much. Lettuce and other vegetables are raised on or near it on the west side of Orange Lake, where there is very little rock.
 Clay soils. Upland soils distinctly clayey at the surface, and containing as much as one-fourth clay, are rare in peninsular Florida. The mechanical analyses farther on which show high percentages of clay are nearly all calcareous hammock soils, and the "clay" in them is probably mostly humus and marl. In the Middle Florida hammock belt, north of the "Ocala area" (e.g., around Fairfield), and in the central part of the Hernando hammock belt, there are some soils clayey enough to form clods when plowed. No me-, chanical analyses of these, are available, but chemical analyses of two of the Hernando County soils are given under V and W. On such soils short-leaf pine, sweet gum and hickory are characteristic trees, and a good deal of corn and other staple crops are. raised, with little or no fertilizer. The whole aspect of the country strongly suggests some places in Georgia and Alabama.

 DAMP SOILS
 Sandy. Under the.head of damp sandy soils are classed most of the soils of the Gulf hammock region and the three flatwoods re-
