162 FLORIDA GEOLOGICAL SURVEY-THIRD ANNUAL REPORT.
Another well three and one-half miles northeast of Bostwick was drilled in 19o6. This well is now owned by the R. W. Mattox Company and is used for the general supply around the turpentine camp. It is a three-inch well and reached a total depth of 215 feet.
CRESCENT CITY.
Crescent City lies in southeastern Putnam County on the western shore of Crescent Lake. Immediately along this western border flowing wells are obtained.
The first flow of water at this locality is obtained f rr a shell stratum lying from 30 to 6o feet below the surface. Most of the wells at Crescent City terminate at this depth. In some instances this shell stratum isreported absent and in such cases the water is reported as coming from a very fine sand. The water from this depth is usually more or less hard and is impregnated 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 Crescent City is obtained at a depth of about 300 or 316 feet. From the immediate vicinity of Crescent Lake westward to the St. Johns River flowing wells are not ob. tained. 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 diamater, while one is six inches in diameter. They are all reported as reaching a depth of approximately 316 feet, and cased about IOO feet. The wells are located on Crescent Lake and have approximately the same elevation. The head is reported 20 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
