164 FLORIDA GEOLOGICAL SURVEY—THIRD ANNUAL REPORT. 
detic Survey is thirteen feet above sea. Records from 35 weiU 
have been obtained from and in the vicinity of Palatka. 
The first flowing water encountered at Palatka is obtained from 
a shell stratum at a depth varying from 30 to 60 feet. A great 
many wells in the city terminate at this depth. The water from 
this formation is more or less hard but is not so strongly impregna¬ 
ted with hydrogen sulphide gas as is the water from the deeper 
water bearing formations. 
These more shallow wells at one time ceased to flow and pumps 
had to be resorted to. When the deeper wells were put in, the shal ¬ 
low wells in this vicinity commenced flowing again. As an 
instance of this the well now owned by Messrs. L. H. and W. A. 
Merryday and located in the yard of the Putnam House may be 
cited. This is a two-inch well and is 50 feet deep. It is reported 
as being cased the total depth. The well # flowed when first put in 
but in subsequent years had ceased to flow. During the year 1908 
Mr. H. Mervin drilled a four-inch well for Dr. G. E. Welch about 
two blocks to the north. This well reached a total depth of 220 
feet and is reported cased 120 feet. Immediately on the comple¬ 
tion of this well the Merryday well commenced to flow. This 
seems to indicate that these wells are supplied with water through 
leakage from the wells reaching the deeper water bearing strata. 
The principal flow in and near Palatka is obtained from a depth 
of 175 to 250 feet. At this depth an abundance of water is obtain¬ 
ed having a head varying from 18 to 26 feet above sea. A meas¬ 
urement was made of the pressure in the well of A. D. Curry about 
three-fourths of a mile southwest of Palatka in December, 1909. 
The well at this time was found to have a pressure of eleven and 
one-half pounds. The pressure was taken at the top of the pipe 
which stands about two feet above the surface of the ground. 
A number of wells have been put down across the river and in 
the vicinity of East Palatka. The elevation of the depot at East 
Palatka as given by the Coast and Geodetic Survey is seventeen 
feet above sea level. A four-inch well drilled for H. Hanna at 
this place by N. H. Monck in 1909 reached a depth of 225 feet. It 
is reported cased 135 feet and the water is reported as rising fifteen 
feet above the surface. A second well drilled for the Florida East 
Coast Railway by N. H. Monck in 1909 was drilled to a depth of 
256 feet. This is a four-inch well and is reported cased 135 feet. 
The water is said to rise fifteen feet above the surface. 
The following is an analysis of the water from the city well at 
Palatka. The water was sent in by Dr. E. S. Crill. Analysis made 
in the office of the State Chemist, B. H. Bridges, analyst.
