 water power development. A part of 

 the Blue Ridge Mountain section of 

 northeastern Georgia. Extent of area 

 suitable for preservation not known. 

 Not examined in person. Readily

8. FLORIDA 



BY J. R. WATSON 1 



I. GENERAL CONDITIONS 



1. Topography and soil 



Florida is geologically, physiographi- 

 cally, and ecologically young; progres- 

 sively so from north to south. Its 

 physiographic youth is shown by its 

 generally poor drainage, numerous 

 swamps and shallow lakes, sluggish, 

 ill-defined, crooked streams with low, 

 generally swampy banks. 



Much of the northwestern portion is 

 hilly and rolling; a broken north and 

 south ridge divides the drainage of the 

 east and west coasts. The highest 

 elevation above sea level is about 300 

 ft. Along a considerable part of the 

 west coast and nearly the whole eastern 

 coast extends a line of sandy reefs and 

 narrow islands enclosing narrow shallow 

 bodies of salt water, often called "riv- 

 ers/ 1 viz., "Indian River," "Halifax 

 River," etc. 



The underlying rock is largely lime- 

 stone. The central region is remarkable 

 for its large number of lakes (Lake 

 County alone has 1400) largely sink- 

 holes due to solution of limestone. The 

 numerous subterranean streams are of 

 similar origin. 



2. Climate 



Owing to its long stretch from north 

 to south and the fact that the southern 

 part is a narrow peninsula with warm 

 seas on both sides, Florida presents a 

 great diversification of plant and animal 

 life. In fact there is much difference 

 beween the vegetation of the northern 

 and the extreme southern portions of

 versity of Florida, on reptiles by Prof. Rogers and

 tera of south Florida by D.Marston Bates, a student 

 in the University of Florida. Mr. A. H. Howell 

 suggested a number of important changes in the 

 original draft.
