WATER SUPPLY OF EASTERN AND SOUTHERN FLORIDA. 221 
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 estimated to be about 12 feet above Lake Jessup, which estima¬ 
tion 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 re¬ 
sulted from the increased depth, although no exact measurements 
regarding this were made. 
VOLUSIA COUNTY. " ! i ■; 1 
LOCATION AND SURFACE FEATURES. 
Volusia County lies between the St. Johns River and the At¬ 
lantic Ocean. It joins St. Johns County on the north and Bre¬ 
vard County on the south. The area of the land surface of this 
county is approximately 1,281 square miles. Much of the eastern 
part of the county is level and consists largely of palmetto flat- 
woods. 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 including much sandy pine land. Numerous lakes 
occur in this upland section which forms a part of the lake region 
of Florida. Elevations above sea level recorded by the Atlantic
