FLORIDA GEOLOGICAL SURVEY—THIRD ANNUAL REPORT. 
inch well drilled in 1907 by Capt. Alexander Near. It reached 
a total depth of 318 feet and is cased 100 feet. The pressure of 
the well as indicated by the pressure gauge March 15, 1910 was 
T 7 /^ pounds. This gives the well a head of 40.4 feet above the 
surface, or estimating the surface elevation of the well to be 12 feet 
above the river level, a total head of 52.4 feet above the level of the 
water in Indian River. From an examination of a mixed sample 
from the drillings of this well it is seen that the Vicksburg Lime¬ 
stone is reached. From Mr. Gibbs’ record made at the time the well 
was drilled it would appear that this formation was encountered at 
a depth of 221 feet. The log as made out by Mr. Gibbs is as fol¬

MERRITTS ISLAND. 
From the well records obtained in this locality it is probable 
that flowing artesian wells can be obtained at any point on Mer- 
ritts Island. Record of wells are on file from every postoffice on 
the island bordering the Indian River. Also, records have been 
obtained from Artesia, Cape Canaveral Light House, and Canaveral 
Club House on the peninsula east of the island, good flows being 
reported from all of these localities. The pressure of two of the 
wells on the southern end of the island was obtained, one at Lotus 
and one at Tropic. The well of L. D. Hancock, 1 mile south of 
Lotus has a depth of about 300 feet. The pressure of this well 
March 12, 1910, was 16 pounds. The elevation of the well accord¬ 
ing to barometric readings is 10 feet. This together with a pres¬ 
sure of 16 pounds gives the well a total head of 46.9 feet above the 
level of the water in Indian River. The following is an analysis 
of the water from this well. Analysis made for the State Survey 
in the office of the State Chemist, A. M. Henry, analyst.
