PRINCIPAL RESULTS OF THE STATE GEOLOGICAL SURVEY 
INVESTIGATIONS. 
Aside from miscellaneous and routine work, the principal 
investigations that have been carried out by the State Geological 
Survey since its organization may be grouped under six heads 
as follows: 
I. Assemblage of the literature on the geology of Florida 
and a review of the important publications issued previous to the 
organization of the State Survey. This review of the literature 
together with the bibliography of publications relating to the 
geology of Florida was included in the First Annual Report. The 
publications obtained in this connection form a part of the Survey 
library. 
II. A Report on the Geology and Stratigraphy of Florida. 
This report included in the Second Annual Report was prepared 
in cooperation with the United States Geological Survey. It 
serves as a preliminary account of the geology of the State, and 
brings together all the information relating to the geology that 
was then available. 
III. A General Topographic and Geologic Map of Florida. 
With the general report on the geology of Florida referred to 
above there was included a topographic and geologic map of Flor¬ 
ida. The topography was shown on this map with as much detail 
as the information available regarding elevations would permit, 
the contour lines being placed at 50 foot intervals of elevation. 
A second edition of this map is included in the report now being 
issued. 
IV. A very important natural resource of Florida is the 
underground or artesian water supply. This subject was one of 
the first taken up by the Survey, and with the publication of the 
present report the preliminary investigation of the water supply 
is completed. The papers published on this subject are as follows:
