as 175 or 180 feet. At a depth of 315 feet light-colored calcare¬ 
ous sands were penetrated. It is probable, as these wells seem 
to indicate, that the Vicksburg Limestone here, as at some other 
localities, has a very irregular top surface. 
AREA OF ARTESIAN FLOW IN PUTNAM COUNTY. 
The flowing area of Putnam County includes a relatively 
narrow strip bordering the St. Johns River and its tributaries. 
Upon leaving the river the elevation rises and flowing wells are 
not obtained. The flowing area in this county is indicated by 
shading on the map. 
LOCAL DETAILS. 
BOSTWICK. 
Flowing wells are obtained at Bostwick. A three-inch well, 
drilled in 1904 for J. W. Glisson by H. Mervin, reached a total 
depth of 248 feet. This well is reported cased 60 feet and the 
water is reported to rise 18 feet above the surface. 
Another well three and one-half miles northeast of Bostwick 
was drilled in 1906. This well is now owned by the R. W. Mat¬ 
tox Company and is used for the general supply around the tur¬ 
pentine 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 west¬ 
ern border flowing wells are obtained. 
The first flow of water at this locality is obtained from a 
shell stratum lying from 30 to 60 feet below the surface. Most 
of the wells at Crescent City terminate at this depth. In some 
instances this shell stratum is reported 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 impreg-
