MERRITTS ISLAND. 
From the well records obtained in this locality, it is probable 
that flowing artesian wells can be obtained at any point on Merritt 
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 Cana¬ 
veral 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, one 
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, according to barometric readings, is 10 feet. This, together 
with a pressure 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,
