FLORIDA STATE GEOLOGICAL SURVEY. 
Along the East Coast wells are in use as far as the southern line 
of the county. It is probable that flowing wells can be obtained 
for some miles inland from the coast. 
LOCAL DETAILS. 
EDEN. 
A four-inch well at Eden, owned by Mr. Chas. Edison, was 
sunk by Messrs. Fee & Nesbitt and is 870 feet deep. The water is 
used for general and irrigation purposes. It rises 25 feet above 
the surface. It is a hard water and is impregnated with hydrogen 
sulphide. 
FT. PIERCE. 
Two artesian wells occur at Ft. Pierce, the county seat of St. 
Lucie County. These are <?wned by the St. Lucie Ice Company. 
The wells are reported to have a depth of 812 feet. One is six 
inches in diameter, the other 2 inches, and both are reported cased 
200 feet. The first flow is said to have been obtained from lime¬ 
stone, at a depth of from 725 to 750 feet. The last 100 feet of 
the well is said to have been through this limestone. The follow¬ 
ing is an analysis of the water from one of these wells. Analysis 
by the Geo. W. Lord Company, 2238-2250 North Ninth Street, 
Philadelphia, Pa., Chester Alsmere, chemist, reported January 
18, 1907: 
Constituents. Parts per million. 
Organic and volatile matter . 51.311 
Calcium oxide. 70.650 
Magnesium oxide . 31.939 
Sodium oxide . 736.846 
Sulphur trioxide . 241.489 
Chlorine . 446.737 
Carbonic acid (combined) . 204.081 
Silica . 33.979 
As will be seen in the above analysis this water contains a high 
percentage of sodium and chlorine. The water tastes brackish, 
and is used for cooling purposes in the manufacture of ice. The
