Lake shores, etc. About So% of the large trees and shrubs, but not so many of thi small trees and vines, are evergreen. This difference is probably due to the fact that the small trees and vines are chiefly confined to hammocks with richer soil, as in regions 2 and 5. Population. In attempting to estimate the densityy of population we encounter the same difficulty as in most of the regions previously described, for this belt does not cover as much as half of any one county. But there must be at least forty persons per square mile. As this is evidently the most populous part of Hernando and Pasco Counties, the figures for those counties may represent the composition of the population fairly well. In 1910 they had 56-57 of native whites, 1.6% of foreign whites, and 41.8% of negroes. The percentage of illiteracy (in the population over 10) was 3-1 among the native whites, 8.9 among the foreign whites, and 31.2 among the negroes. The last is the highest figure found in central Florida, and that for foreign whites is rather high, too, but both may be due to a large number of unskilled laborers in the phosphate mines of Hernando County, which are entirely outside of the hammock belt.
