9. PENINSULAR FLATWOODS, EASTERN DIVISION 



(Figs. 26-28. Soil analysis Y.) 



The flatwoods east of the lake region cover about 3,600 square 

 miles in the counties under consideration (since Flagler and Okee- 

 chobee were cut off from Volusia and Osceola), At the north, 

 somewhere about the boundary between Flagler and Volusia Coun- 

 ties, there is a gradual transition from the peninsular flatwoods to 

 the East Florida flatwoods (described in the 6th Annual Report). 

 The most conspicuous difference between the flatwoods of East 

 Florida and those of the peninsula is that the cypress ponds of the 

 former nearly always have some slash pine in them, while in the 

 latter the pine usually stops several yards outside of the cypress, 

 leaving the ponds bordered by treeless strips. The cause oi this 

 difference is not yet known, but is probably connected with the 

 soil. 



Geology. The strata near the surface are so featureless that the 

 whole area is usually mapped as Pleistocene. Considerably older for- 

 mations occur at no great depth, however, the Ocala (Eocene) being 

 encountered in wells along the east coast within 200 feet of the sur- 

 face. The surface is generally covered with deep sand, but there 

 is marl, presumably Pleistocene, in some hammocks and low spots, 

 and peat in some of the prairies and around lakes. Flowing ar- 

 tesian water can be obtained near the coast and along the St. John's 

 and Kissimmee Rivers and their lakes, but in about the latitude 

 of Titusville the water in some of the wells is salty. 



Topography. The surface is for the most part monotonously 

 level, and seems to be nowhere more than 100 feet above the sea. 

 Near the east coast south of Titusville, however, the general level
