nated with 'hydrogen sulphide gas. These wells are reported to 
have a head of about 15 or 16 feet above the surface. 
The second flow in and near Orescent City is obtained at a 
depth of about 300 to 316 feet. From the immediate vicinity of 
Crescent Lake westward to the St. Johns River flowing wells 
are not obtained. The intervening country includes rolling, sandy 
hills. Surface wells, terminating in the sands and sandy clays 
furnish an abundant supply of soft water. 
Aside from the use of private wells, Crescent City is supplied 
with water from four artesian wells. The water supply system 
is under private ownership. Two of the wells are two inches in 
diameter, while one is six inches in diameter. They are all re¬ 
ported as reaching a depth of approximately 316 feet, and cased 
about 100 feet. The wells are located on Crescent Lake and have 
approximately the same elevation. The head is reported 26 feet 
above the surface or about 27 feet above the level of the water 
in Crescent Lake. In addition to supplying the town the flow 
from one two-inch well is used for condensing purposes and for 
the manufacture of ice. Part of the flow from the other three 
wells is used for power to run an overshot wheel, which in turn 
runs a pump, pumping the surplus flow of water to a reservoir 
or tank where the water is distributed to different parts of the 
city by gravity. 
ORANGE MILLS. 
Orange Mills is located on the Florida East Coast Railway, 
midway between Hastings and East Palatka. The wells in this 
vicinity are used for the purpose of irrigation. The depth of 
the wells range from 143 to 200 feet. All of the wells of which 
record 'has been obtained are four inches in diameter. The length 
of casing used in the wells averages 60 feet. 
Four wells drilled for J. H. Bahrenberg & Brother by N. H. 
Monck in December, 1909, gave the following pressure: Well 
No. 1 is 143 feet deep and is cased 65 feet. The pressure of this 
well as shown by the pressure gauge December 4, 1909, was 5$4 
pounds. Well No. 2 is 160 feet deep and is cased ?’4 feet. The
