subsequent years decreased in flow, and in order to get a sufficient 
amount of water for general use it became necessary to deepen 
the well. In 1905 'Captain Alex. Near continued the drilling to 
297 feet. The well now gives an abundance of water strongly 
impregnated with hydrogen sulphide and tasting slightly brackish, 
although not so much so as to condemn it for general purposes. 
CITY POINT. 
Flowing wells are obtained along the shore of Indian River 
at City Point. Between the village on the river and the City 
Point depot, on the Florida East Coast Railway, there is quite 
an elevation, evidently an old sand dune. The elevation of this 
ridge, according to barometric readings, is about fifty feet above 
the level of the water in the river. A well sunk here some years 
ago failed to flow, although the water rose to within a few feet 
of the surface. A well owned by S. Plendry is reported to have 
a depth of about 160 feet. The elevation of the well is approxi¬ 
mately twenty feet above the water in Indian River. The pressure 
of this well, as indicated by the pressure gauge March 5, 1910. 
was five pounds, or sufficient pressure to cause the water to rise 
11.5 feet above the surface, or approximately 31.5 feet above the 
river level. 
The following is an analysis of the water from this well. An¬
