LETTER OF TRANSMITTAL. 
To His Excellency, Hon. Albert W. Gilchrist, 
Governor of Florida. 
Sir:—In accordance with the Survey Law I submit herewith a 
report of the progress of investigations made by the Geological 
Survey for the year ending June 30, 1910. The work of the Survey 
has progressed actively during the past )^ear. This report contains 
papers on the phosphate deposits, the peat deposits, the lakes and 
the artesian water supply. 
In connection with the report on water supply I would respect¬ 
fully call attention to the evidence of the loss of flow in some of 
the artesian wells, and to the danger of a material reduction in the 
artesian supply in some localities, if the waste of water is not pro¬ 
hibited by. law. 
The generous interest you have taken in the work of the State 
Survey is appreciated. 
Very respect fully, 
E. H. Sell ards. 
State Geologist. 
Tallahassee, Florida, 
October 1, 1910.
