174 FLORIDA GEOLOGICAL 5URVEY—THIRD ANNUAL REPORT. 
lying formations is very meager. In the city well at DeLand the 
first water was obtained at a depth of 113 feet after passing through 
eight feet of clay and entering a twelve-foot shell stratum. The 
stratum of shell overlies a bed of rock reported to be 24 feet thick. 
The next rock encountered is at a depth of 237 to 247 feet. At 
Daytona the Vicksburg Limestone as shown by the comparatively 
shallow depths of the wells lies close to the surface and is presum¬ 
ably reached at from 123 to T50 feet. 
AREA OF ARTESIAN FLOW IN VOLUSIA COUNTY. 
The area of artesian flow in Volusia County is confined to a 
strip bordering the Atlantic Ocean on the east and a strip on the 
west bordering the St. Johns River. This area is indicated on the 
accompanying map. There are no doubt areas not mapped where 
flowing wells can be obtained. The area mapped, however, is based 
on definite information and on well records. In the northern por¬ 
tion of the county flowing wells are obtained as far west as Cres¬ 
cent Lake. This part of the county is flat and of low altitude. 
LOCAL DETAILS 
DAYTONA. 
Daytona lies in the flowing artesian section in eastern Volusia 
County along the western bank of Halifax River. The city is sup¬ 
plied with water from four artesian wells, all of which are six inch¬ 
es in diameter. These wells were drilled in 1909 but in order to 
obtain an increased flow were deepened in 1910 and now range in 
depth from 165 to 260 feet. The 260 foot well on April 7, 1910, 
had a head of 9.3 feet above the surface or approximately 13.3 feet 
above sea. The wells now furnish an abundant supply of hard 
sulphuretted water. 
In addition to the city wells above mentioned numerous private 
wells occur in and near Daytona. Of these it is possible to list only 
a few. Mr. Paul Petion owns a two-inch well about two and one- 
half miles south of the city. The well was drilled by Mr. H. Van- 
Dorn in 1910. It is 145 feet deep and is cased 85 feet. The first 
flowing water is reported to have been encountered at a depth of 
85 feet after drilling through about one foot of hard rock. 
Messrs. Bellough and Melton completed a two-inch well for Mr. 
Chas. Lee about two miles southwest of Daytona in April, 1910. 
This well is 130 feet deep and has a head of five feet above the 
surface. The first flow is reported from a depth of 88 feet just
