GEOGRAPHY OF CENTRAL FLORIDA 105

Surface streams are few and small, and probably none of them connect above ground with any river. Just north of our limits there are a few large shallow lakes which become dry or nearly so- at times. The highest elevations in the region seem to be about 190 feet above sea-level.
 Soils. By both chemical and physical tests the soils average the best in central Florida, running pretty high in clay and in lime, as can be seen from the analyses in another chapter. In the soil survey of the "Ocala area" they are referred to the "Gainesville," "Norfolk," "Fellowship" and "Leon" series, and the, texture classes, in order of area, are loamy sand, sandy loam, sand, and clay loam, the first constituting about 38% and the last about 1%. Scrub seems to be entirely absent.

 Vegetation. The vegetation types of the southern extremity of.the region were described in considerable detail and mapped in the 7th Annual Report. In order of area the principal types seem to be high pine land, red oak woods (fig. 41), high calcareodis (or semi-calcareous) hammocks (fig. 13), short-leaf pine and hickory woods (this mostly north of the "Ocala area"), sandy hammocks
