WATER SUPPL,Y OP EASTERN AND SOUTHERN EEORIDA. 243 
feet above the surface. The first flow was encountered at 70 feet 
and it is reported by the driller, Capt. W. H. Sharpes, that neither 
the head nor the volume increased with the depth. As indicated 
from the well records and from all obtainable information, only a 
small amount of casing was used in the wells in this vicinity, and 
a knowledge as to whether or not fresh water was encountered 
below the stratum of salt water is, therefore, lacking. 
The following is an analysis of the water from the well of J. 
J. Ollif, Sharpes, Fla. This well is near the Spafford well and 
approximately one mile north of the Hendry well, at City Point, 
analysis of which is given on page 234. Analysis made for the 
State Survey in the office of the State Chemist, A. M. Henry,

TILLMAN. 
The only deep well at Tillman, of which record has been 
obtained, was drilled by John McAllister, in 1890, and is owned 
by R. A. Conkling. It is 350 feet deep and furnishes an excellent 
flow of water, which is used for general domestic purposes. 
TITUSVILLE. 
Titusville, the county seat of Brevard County, is located on the 
Indian River. Several artesian wells have been sunk at this 
locality, but up to the present time principally salt water has been
