REVIEW OF THE GEOLOGY OF FLORIDA

lying apparently at less than 100 feet from the surface. The 
depth to the Eocene has been determined approximately at a few 
inland towns in this area. At Sanford fossils of the Ocala forma¬ 
tion have been identified by Cushman at the depth of 113 feet. 
The surface level at the old railway depot at Sanford is given as 
20 feet above sea. The surface level at the well is not known but 
probably does not differ greatly from the level at the depot. The 
top surface of the Eocene, therefore, is probably somewhat less 
than 100 feet below sea level. At Orange Mills the limestones, 
probably Eocene have been reported at a depth of 130 feet, the 
surface elevation at this place being about 15 feet above sea level. 
A slightly increased depth to these limestones is suggested by well 
records at Hastings. 
In the well of the Palmetto Phosphate Company in Polk County 
the top of the Ocala is placed by Cushman at 360 feet. The sur¬ 
face elevation at Ft. Meade is about 130 feet above sea. The ele¬ 
vation at the well being not greatly different from that at Ft. 
Meade, the actual level of the top surface of the Ocala formation 
in this well is probably between 200 and 235 feet below sea level. 
The following is a description of a few samples received from 
a deep well drilled in 1915 for the city of New Smyrna. Samples 
submitted by F. A. Newell, City Clerk. 
Record of Samples from City Well of New Smyrna. 
Depth from, 1 the surface: 
93 to 105 feet. Greenish, sandy, calcareous and phosphatic rock, some sharks 
teeth and fragments of shell. 
105 feet. Sample containing a greenish rock and some fragments of white 
limestone. 
105 feet. Pure white granular, porous limestone. 
181 feet. Light colored granular limestone. 
265 feet. Limestone, slightly brownish cast. 
285 to 296 feet. Limestone, mostly light brown in color. 
290 feet. Limestone^ mostly light brown in color, 
1022 feet. Brown limestone. 
Interpretation: The sample representing material from 95 to 
105 feet shows that the phosphatic and calcareous materials lying 
above the limestones extend to a depth of 105 feet, these samples 
appear to represent the Miocene, chiefly or entirely. From 105 
feet to the bottom of the drill hole is limestone which varies in
