THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA. 
173 
The well of Mr. E. Hy. Palmer, seven miles south of Sanford, 
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. The 
pressure of this well as indicated by the pressure gauge April 26, 
1910, 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 esti¬ 
mated 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 in¬ 
ches 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 de¬ 
tailed record of the well could not be obtained but it was stated by 
Mr. Pace that no apparent increase-in head resulted from the in¬ 
creased 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 Atlan¬ 
tic 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. Bor¬ 
dering the Atlantic Ocean, however, is an extensive strip of ham¬ 
mock 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 includ¬ 
ing much sandy pine land. Numerous lakes occur in this upland 
section which forms a part of the lake region of Florida. Eleva¬ 
tions above sea level recorded by the Atlantic Coast Line Railroad 
which traverses this ridge are as follows: Seville, 52 feet; Pierson, 
78 feet.
