9S FLORIDA GEOLOGICAL SURVEY—FOURTH ANNUAL REPORT. 
McDAVID. 
A well for the town of McDavid was sunk in 1910 by Mr. R. B. 
Bell. This is the northernmost flowing well in the county being 
only about 10 miles from the northern boundary. The total depth 
is 74 feet and a good flow of soft water rising about 10 feet above 
the surface is obtained. The depot at McDavid according to ele¬ 
vations by the Louisville and Nashville Railroad is 74 feet above 
sea. This town well is only a short distance from the depot and has 
about the same elevation, thus giving it a head of approximately 
84 feet above sea. Another flowing well at this place is the one 
owned by the Mayo Lumber Company which was sunk by Mr. Bell 
in 1909. This well reaches a depth of 143 feet and furnishes a good 
flow of soft water, which is reported to come from a formation of 
gravel as was also the case in the well listed above. A third well 
sunk by Mr. Bell in this neighborhood is that of Mr. W. E. Tomp¬ 
kins which is 130 feet deep and is non-flowing. The water is report¬ 
ed to stand 30 feet below the surface. The elevation here is consid¬ 
erably more than at the depot which probably accounts for the 
water not rising above the surface. The general water supply for 
McDavid and vicinity is from wells 40 to 60 or more feet in depth 
terminating in the underlying sands and sandy clays. 
PENSACOLA. 
The range of the depth of the artesian wells in and around 
Pensacola is from 130 to 200 feet. Wells of this depth near the 
bay shore obtain a flow while the water in those located on higher 
ground rises to within a few feet of the surface. A great number 
of wells are found here, but as all have similar records only a few 
will be mentioned. The city of Pensacola is supplied with water 
from 16 wells averaging 130 feet in depth and ranging from 4 to 6 
inches in diameter. The first of these was sunk in 1886. The water 
in these wells stands 16 feet below the surface. It is said that no 
decrease in the supply has been noticed, although on account of 
increased consumption of water, which is now (March, 1911) 
1,200,000 gallons daily, additional wells have had to be added 
from time to time. The water from these wells is an excellent soft 
water with a slight taste of iron. The following four analyses of 
water representing the city water supply were made by Dr. George 
A. Roper, of New York City, and were reported September 26, 1902. 
At the time these analyses were made the water system was owned
