21 FLORIDA STATE GEOLOGICAL SURVEY. 
The well of Mr. A. J. McCulley is To feet deep, two inches in 
diameter and is cased TO feet. This well was sunk by the owner 
in 190T. The water is reported to rise to within 14 feet of the 
surface. Mr. McCulley owns another two-inch well which is T3 
feet deep, and is' cased 68 feet. The water in this well is said to 
rise to within three feet of the surface. This apparent difference 
in head is due largely to a difference in elevation of the wells. 
A two-inch well, 11T feet deep, one and one-quarter miles 
west of Oviedo, was completed for Mr. D. W. Curry in 1910 
by Mr. A. J. McCulley. This well gives a good flow of sulphur 
water and had, when measured in April, 1910, a pressure of four 
and one-quarter pounds, the measurement being made about five 
feet above the ground. The first flow in this well was encoun¬ 
tered at a depth of T9 feet. 
A well fourteen miles east of Oviedo, on the Econlockhatchee 
Creek, furnishes a flow of salt water. This well was drilled in 
190T by A. J. McCulley and is 114 feet deep, two inches in diam¬ 
eter, and is cased T5 feet. The first flowing water, which was 
salty, was found at a depth of TO feet. 
SANFORD. 
Probably not less than 1,000 wells 'occur in and around San¬ 
ford. These wells are used for irrigating purposes and obtain 
flowing artesian water at a comparatively shallow depth, the 
average being from 125 to 200 feet. Bordering Lakes Monroe 
and Jessup and the St. Johns River, the wells are more shallow 
and terminate at a depth of from 66 to 85 feet. 
The first flow in the wells at Sanford is encountered at a 
depth of from 100 to 125 feet, after drilling through a rock more 
or less hard and penetrating the characteristic “water rock” or 
the Vicksburg Limestone. In some instances a light flow is 
obtained above this harder rock immediately overlying the Vicks¬ 
burg. When such is the case it seems the water comes from a 
quicksand or sometimes from a stratum of sand and shell. In 
order to get a sufficient and permanent flow, however, the boring 
is continued until the Vicksburg Limestone is reached.
