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, i9io. The work of the Survey has progressed actively during the past year. 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 respectfully 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 prohibited by law.
The generous interest you have taken in the work of the State Survey is appreciated.
Very respectfully,
E. H. SELLARDS,
State Geologist.
Tallahassee, Florida,
October i, 19IO.
