when removed will re-forest itself naturally, but on the very sandy 
soils the pine when cut off is quickly replaced by a dense growth of 
scrub oaks. 
The rolling pine lands are too extensive to call for specific refer¬ 
ence to areas. The interior of the State is chiefly of this type. A 
large number of soil types are included which can be properly sep¬ 
arated and mapped only by detailed soil surveys. The pine lands in 
the limestone sections of the State present many differences in 
topography, in drainage, and in the grade of soils, from the pine 
lands in the non-limestone sections. 
The following is an analysis of a sample of the well drained 
pine land of Osceola County. The principal vegetation is pine and 
scattered oak, and wire-grass. The sample was collected by R. E. 
Rose. The analysis is taken from Bulletin 43 of the State Experi¬ 
ment Station.

The following analysis is also taken from Bulletin 43 of the State 
Experiment Station. This sample was collected by C. W. Wilson, 
and was taken from near Lake Elbert in Polk County. The principal 
growth upon the land is small pine, with more or less oak. The 
sample represents the sandy rolling lands of the lake region:
