THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA.

The well of Mr. E. Fly. Palmer, seven miles south ,,)f Sainford, near the western shore of Lake Jessup, is 75 feet deep and was drilled in 1907. This is a four-inch well and is cased 40 feet. Th4 pressure of this well as indicated by the pressure gauge April 26, I9IO, was nine and one-half pounds, or a pressure sufficient to cause the water to rise 21.9 feet above the point of connection of the gauge which was three feet above the surface. The well is estimated to be about 12 feet above Lake Jessup, which estimation will give the well a total head of 36 feet and 9 inches above the surface of the lake.
The deepest well at Sanford is the well owned by Mr. J. E. Pace. This well is located just outside of the known flowing area and was sunk in the hopes of obtaining a flow. The well is six inches in diameter to a depth of five hundred feet below which depth the size of the drill hole was reduced to'four inches. It has a total depth of 670 feet and the water rises to within one and one-half feet of the surface. The well is reported cased only 94 feet. A detailed record' of the well could not be obtained but it was stated by Mr. Pace that no apparent increase in head resulted from the increased depth, although no exact measurements regarding this were made.
VOLUSIA COUNTY
LOCATION AND SURFACE FEATURES.
Volusia County lies between the St. Johns River and the Atlantic Ocean. It joins St. Johns County on the north and Brevard County on the south. The area of the land surface of this county is approximately 1281 square miles. Much of the eastern part of the county is level and consists largely of palmetto flatwoods. Bordering the Atlantic Ocean, however, is an extensive strip of hammock known as Turnbull Hammock. Back of the hammock is found the line of sand dunes. Bordering the St. Johns River is found some open flatwoods. Running in a general north and south direction through the western part of the county is a ridge includiing much sandy pine land. Numerous lakes occur in this uplaid section which forms a part of the lake region of Florida. Elevations above sea level recorded by the Atlantic Coast Line Railroad which traverses this ridge are as follows: Seville, 52 feet; Pierson, 78 feet.
