average for northern Florida, presumably indicating more potas- 

 sium and more humus in the soil than in most of the other regions. 

 Economic Feakires — This region contains a large amount of 

 hardwood timber, which has not been utilized much yet, but will 

 doubtless be more appreciated in the future. The area is so narrow 

 and irregularly shaped that it is impracticable to work out any 

 statistics of its population and agricultural features. Although the 

 soil is rich enough, the broken topography interferes with culti- 

 vation to a considerable extent.
