124 FLORIDA GEOLOGICAL SURVEY— FOURTH ANNUAL REPORT. 
the valley of the Apalachicola River. The area in which flowing 
wells may be expected in this county is shown on the map on page 
335. 
LOCAL DETAILS. 
BLOUNTSTOWN. 
Blountstown, the county seat of Calhoun county is located on 
the Apalachicola River. One deep well has been drilled at this 
place from which desirable flowing artesian water was obtained. 
The well is four inches in diameter, 234 feet deep, and is cased 60 
feet. It was drilled in 1910. 
buckhorn. 
One deep well is reported from Buckhorn. This well was drilled 
in 1910 for Gaskin and Kentz. It is four inches in diameter, 270 
feet deep and is cased 160 feet. The water rises to within 15 feet 
of the surface. 
PORT ST. JOE. 
The Apalachicola Northern Railroad have a well at Port St. 
Joe 115 feet deep drilled in 1911. This well is four inches in diame 
ter and is cased the entire depth. The water stands about five or 
six feet below the surface. In all probability a flowing well could 
have been obtained if the boring had been continued deeper, but 
such was not desired as the water from this well is used principally 
to furnish supplies for the machine shops and boilers. r he water 
from the deeper wells is hard and is not so desirable for boiler use. 
The following is an approximate log of this well kindly given by 
Mr. George E. Dunan, Engineer of Roadway:
