flow, as measured March 10, 1910, was 60 gallons per minute 
and the pressure as indicated by the pressure gauge on the same 
date was five pounds or a pressure sufficient tO' cause the water 
to rise 11.5 feet above the surface. The elevation of the well 
above the level of the water in Indian River, as shown by baro¬ 
metric readings, is 20 feet. This elevation, together with a head 
of 11.5 feet above the surface, gives the well a total head of 31.5 
feet above the river level. The water is the characteristic sulphur 
water common to most of the artesian wells of the State. 
The following is an analysis of the water from this well.

EAU GALLIE. 
The first artesian well in Eau Gallie was drilled, in 1887, by 
John McAllister. This well is now owned by George F. Paddison, 
and is 337 feet deep. It is one and one-fourth inches in diameter 
and cased 136 feet. The depth to the water rock was reported 
by the driller, Mr. McAllister, to be 237 feet. The head of this 
well is given as 42 feet above the surface, or approximately 52 
feet above the level of the water in Indian River. Since the 
completion of the above test well, many wells have been sunk in 
and around Eau Gallie, varying in depth from 315 to 500 feet. 
The principal water supply is obtained at a depth of from 230 to 
315 feet.
