FLORIDA STATE GEOLOGICAL SURVEY. 
Another well owned by N. B. Ivey is located about two miles 
southwest of Green Cove Springs. This well is used for irriga¬ 
tion and was sunk by the owner in 1907. It is a four-inch well 
and is reported to be 500 feet deep. At this depth the water is 
reported to rise five feet above the surface. 
HIBERNIA. 
One well is reported from Hibernia. This well was com¬ 
menced July 20, 1885, and was finished in October of the same 
year. It was drilled by O. H. Wade for F. A. Fleming. The 
well is 468 feet deep, four inches in diameter and is cased 377 
feet. This well when first drilled, in 1885, had a pressure of 23 
pounds. Unfortunately, when visited in January, 1910, the 
pressure could not be obtained. The elevation of the well is 
about 25 feet above the St. Johns River. A pressure of 23 
pounds will cause the water to rise 53.1 feet above the surface, 
or about 68.1 feet above the St. Johns River. The first water¬ 
bearing stratum in this well was, reported at a depth of 400 feet, 
and the first rock noted was at a depth of 120 feet. 
The following is an analysis of the water from this well drawn 
December 17, 1909. Analysis made for the State Survey in the 
office of the State Chemist, A. M. Henry, analyst:
