122 FLORIDA GEOLOGICAL SURVEY—FOURTH ANNUAL REPORT. 
well is eight inches in diameter. The water is hard and slightly 
impregnated with sulphur. An analysis of this water by the State 
Chemist of Florida showed the total solids to be 165 parts per mil¬ 
lion parts water. 
A well drilled by Mr. White in 1910 for Mr. Monroe Kirkland 
reaches a depth of 225 feet and is cased 138 feet with six inch casing. 
The water comes to within twelve feet of the surface. The first 
rock encountered was reported to be at the depth of 138 feet the 
casing terminating on this rock. 
GREENWOOD. 
Several artesian wells have been drilled at and in the vicinity 
of Greenwood. These range in depth from about 150 to 175 or more 
feet. A well owned by Mr. H. B. Knapp was sunk in 1910. It is six 
inches in diameter and 160 feet deep, and is cased to a depth of 80 
feet. The water is hard and stands about 40 feet below the surface. 
All of these deeper wells terminate in limestone. 
Another well, drilled by Messrs. Jaxon and Knapp for Mr. W. 
Sorey in 1910, is 150 feet deep, four inches in diameter and is cased 
122 feet. The water stands in this well about 50 feet below the 
surface. The following is a log of this well as given by Mr. Knapp:

hard, flinty sometimes, then becomes soft 
and cavernous, cavities containing water. . .120,150 
MARIANNA 
Marianna is the county seat of Jackson county. The city is 
supplied with water from an artesian well 386 feet in depth. It 
is eight inches in diameter and is cased 232 feet. The water rises to 
within 90 feet of the surface. According to barometric readings 
the elevation at the well is 51 feet above the depot or about 140 feet 
above sea. 
The Marianna Manufacturing Company own a six inch well 
located one mile west of the depot at Marianna. It is 150 feet deep 
and is cased to a depth of 125 feet. The water which is hard is 
used for the manufacture of ice and for general purposes. 
At the State Reform School about 3 miles southwest of Marianna 
is a six inch well reported to be 276 feet deep. This well was drilled 
in 1906 bv F. J. White and Company. The water rises to within
