In the area under consideration it seems to be best developed in the lime-sink and lake regions. The soil appears to be essentially the same as in the high pine land, except for such changes as have resuilted from a slight admixture of humus, but the vegetation is entirely different, the main reason being that the hammocks are in situations partly or wholly protected from fire by lakes, streams, swamps or naturally denser fore.sts. 'This point is discussed more fully in the 7th Annual Report, pp. 170-172, where a list of characteristic species can be found.
 The trees are mostly broad-leaved evergreens, so that the ground is pretty well shaded throughout the year. They seem to grow
