INTRODUCTION. 
The following is the third of a series of papers on the water 
supply of the State. The first of these was published in 1908 as 
Bulletin No. 1 and relates to the water supply of eleven counties in 
central Florida as follows: Alachua, Columbia, Citrus, Hamilton, 
Hernando, Lake, Levy, Marion, Pasco, Sumter, and Suwannee. The 
second paper on water supply was published in the Third Annual 
Report, pages 77 to 195, 1910, and included nine counties in eastern 
Florida as follows: Brevard, Clay, Duval, Nassau, Orange, Putnam, 
St. Johns, St. Lucie, and Volusia. This paper, the third of the series, 
includes a report on the water supply of sixteen counties lying west 
of the Suwannee River as follows: Calhoun, Escambia, Franklin, 
Gadsden, Holmes, Jackson, Jefferson, Lafayette, Leon, Liberty, 
Madison, Santa Rosa, Taylor, Wakulla, Walton, and Washington. 
Acknowledgement is due in this as in former papers to the many 
well drillers, well owners and others who have contributed notes 
and records and otherwise assisted in collecting data.
