214 FLORIDA GEOLOGICAL SURVEY I3TH ANNUAL REPORT 



In the western edge of the lake region, northeast of Silver 

 Spring, there is a type of vegetation nearer to low hammock than 

 anything else herein described, but resembling also the swamps of 

 some rivers farther north. This has been described in the 7th 

 Annual Report (pp. 178-179) as short-leaf pine and cabbage pal- 

 metto bottoms.

Sandy hammocks (fig. 39). This is an interesting type of 

 forest, wadely distributed through the sandier parts of the coastal 

 plain from North Carolina to central Florida and Alabama. 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 re- 

 sulted from a slight admixture of humus, but the vegetation is en- 

 tirely different, the main reason being that the hammocks are in 

 situations partly or wholly protected from fire by lakes, streams, 

 swamps or naturally denser forests. This point is discussed more 

 fully in the 7th Annual Report, pp. 170-172, where a list of char- 

 acteristic species can be found. 



The trees are mostly broad-leaved evergreens, so that the ground 

 is pretty w'ell shaded throughout the year. They seem to grow
