THE SOILS OF FLORIDA.

The palmetto flatwoods are extensive and it is to be expected 
that several soil types are included and that these will be found 
to vary in both their chemical and mechanical constituents. Fol¬ 
lowing is the analysis of a typical sample of the soil and sub-soil of 
the flatwoods taken by R. E. Rose in Osceola County. The chief 
vegetation growing upon the soil is pine, saw palmetto and wire 
grass. The analysis is from Bulletin 43 of the State Experiment Sta¬ 
tion, p. 666.
