62 FLORIDA GEOLOGICAL SURVEY—FOURTH ANNUAL REPORT. 
SOIL LITERATURE. 
The most accessible and reliable literature on the soils of the 
state is that which has been issued by the various State and Govern¬ 
ment bureaus. The Florida State Experiment Station has issued a 
number of reports bearing on various phases of soil conditions and 
soil utilization. Among these are the following: A Chemical Study 
of Some Typical Soils of the Florida Peninsula, by A. A. Persons, 
Bull. 43, 1897; Pineapple Culture, Soils, by H. K. Miller and H. EL 
Hume, Bull. 68, 1903; Soil Studies, 1, by A. W. Blair, Bull. 87, 1906 ; 
Soil Studies, 11, by A. W. Blair, Bull. 93, 1908. The reports of the 
State Department of Agriculture include many references to soils, 
and in the various reports of the State Chemist will be found many 
soil analyses. The reports of the United States Department of Agri¬ 
culture contain many general soil studies and a few reports relat¬ 
ing specifically to Florida. The special reports include: A Prelim¬ 
inary Report on the Soils of Florida, by Milton Whitney, Bull. 13, 
1898; and the detailed surveys and maps, a list of which has 
already been given. The areas mapped include Escambia, Gadsden, 
Jefferson, and Leon Counties, and parts of Alachua, Jackson and 
Duval Counties. 
The general literature on soils is extensive. Among the numer¬ 
ous text-book and treatises on soils the following recent publications 
will be found instructive:
