178 FLORIDA GEOLOGICAL SURVEY—THIRD ANNUAL REPORT. 
water is reported to rise to within three feet of the surface of the 
ground. An analysis of the water from this well made in the 
office of the State Chemist showed it to contain 140 parts total 
solids to 1,000,000 parts water. The total solids are reported to be 
cpmposed of calcium carbonate (lime), sodium chloride (common 
salt), and magnesium sulphate (Epsom salts). 
The following is an analysis of the water of the Benson Min¬ 
eral Spring, located about one-fourth mile west of town and 
owned by the Misses Emma and Tina Tucker. Analysis made at 
Vanderbilt University, Nashville, Tennessee, by W. H. Hollenshead.
