HILLIARD.
Hilliard is located in northwestern Nassau County on the Atlantic Coast Line Railroad and about eight miles distant from the St. Marys River. No flowing wells have been reported in this
part of the county, the elevation being too great. The elevation of the depot at Hilliard as recorded by the Atlantic Coast Line Railroad is 66 feet. Mr. D. W. Griffing has kindly furnished several points of elevation covering the property of the Cornwall Farm Land Company.
The only deep well reported at Hilliard is owned by The Cornwall Farm Land Company and was drilled by J. W. Wiggins in 1909. It is an eight inch well, 648k4 feet in depth and cased about 400 feet. The elevation at the well is somewhat above the depot and the water is reported to rise to within 12 feet of the surface.
