COCOA. 
The number of artesian wells in and around Cocoa renders it 
impossible to specifically mention more than a few representative 
ones. The artesian wells in this section terminate at a medium 
depth and are sunk without encountering great difficulty in drill¬ 
ing, thus making the cost comparatively slight. The wells ter¬ 
minate in the Vicksburg Limestone, as indicated by the mixed 
samples of drillings from the well of H. Bradford, one mile south¬ 
west of Cocoa. The water is reported in some instances to con¬ 
tain a trace of salt, but only in a very few cases was it found to 
be injurious to vegetation. 
The well of O. K. Key was sunk by the owner in 1908. It is 
a three-inch well and has a depth of 202 feet. The well is cased 
140 feet. The pressure of the well, as indicated by the gauge, 
March 10, 1910, was ten pounds, or a head of 23.1 feet above the 
surface. The elevation of the well above the level of the water 
in the Indian River, as shown by barometric readings, is 15 feet, 
thus giving the well a total head of 38.1 feet above the water 
level in the river. The water has a slight trace of salt and is 
impregnated with hydrogen sulphide gas. 
About one-fourth mile southwest of the city postoffice is the 
well of the Cocoa Ice Company. This well is reported to have 
been drilled in 1888. It is a four-inch well, 325 feet deep, and 
cased about 125 feet. The pressure of this well in 1908 was re¬ 
ported to be twelve and one-quarter pounds. This pressure would 
give the well a head of 28.2 feet above the surface. The esti¬ 
mated surface elevation is about 10 feet above the river, making 
a total head of 38.2 feet above the level of the water in Indian 
River. 
An artesian well one mile southeast of 'Cocoa was completed 
in February, 1910. This well was drilled by J. A. Coward and is 
owned by H. Bradford. It is three inches in diameter, 190 feet 
deep and is cased to a depth of 80 feet. A mixed sample of the 
drillings taken after the completion of the well indicates that the 
Vicksburg Limestone was encountered. The exact depth at which 
this limestone was reached could not be learned. ’The volume of
