FL,ORIDA STATE GEOLOGICAL SURVEY. 
E. H. SELLARDS, STATE GEOLOGIST. 
ADMINISTRATIVE REPORT. 
The members of the State Survey force during the past year have 
been, in addition to the State Geologist, Mr. Herman Gunter, Dr. 
R. M. Harper, and during a part of the year Professor N. H. Cox. 
The chemical analyses necessary to the work of the State Survey are 
made by the State Chemist. 
Mr. Gunter has assisted in the preparation of the paper on fullers 
earth deposits which accompanies this report. In addition he has had 
charge of cataloguing and recording the Survey collections. 
Dr. Harper’s connection with the Survey began in December, 1908, 
since which time he has been engaged in an investigation of the peat 
resources of the State. The peat deposits form a natural resource the 
value of which can not fail to be appreciated as other fuels become 
exhausted, and Dr. Harper’s report will do much, to further the de? 
velopment of this industry. The fuel tests of peat samples for this 
purpose are being made in the fuel testing laboratory of the United 
States Geological Survey. 
Professor N. H. Cox, of the department of civil engineering of 
the State University, was engaged during the summer of 1908 in an 
investigation of the roads and road making materials of the State. 
In addition to the necessary correspondence and administrative 
work of the office, the State Geologist has completed the field investi¬ 
gations for a preliminary report on the fullers earth deposits, and 
has carried on field work with a view to the publication of a report 
on the phosphate deposits. 
PUBLICATIONS ISSUED. 
Two publications have been issued during the year as follows: 
The First Annual Report covering the operations of the State Geo¬ 
logical Survey for the year 1908-09, and Bulletin No. 1 of the Sur¬ 
vey, on the underground water supply of central Florida. 
The annual report contains: (1) A sketch of the geology of 
Florida; (2) a chapter on mineral industries, including phosphate, 
kaolin or ball clay, brick-making clays, fullers earth, peat, lime and 
cement, and road making materials; (3) a bibliography of publica¬ 
tions on Florida geology with a review of the more important papers
