 9. PEN-INSULAR 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 Okeechobee were cut off from Volusia and Osceola). At the north, somewhere about the boundary between Flagler and Volusia Counties. 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 tlie 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 formations occur at no great depth, however, the Ocala (Eocene) being encountered in wells along the east coast within 200 feet of the stirface. 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 artesian 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
