AGE OF THE UNDERLYING ROCKS OF FLORIDA 
PROBABLE STRATIGRAPHY. 
The occurrence of Lepidocyclina somewhere between 95 and 
100 feet indicates Oligocene strata in this section. 
The occurrence of typical Ocala species at 113 feet and below 
very clearly indicates this formation at that depth. 
From the record at Apopka and at other points it is probable 
that the Ocala rests upon the Lower Cretaceous here. 
WELL OF H. BRADFORD, AT COCOA, BREVARD 
COUNTY, FLORIDA. 
A single sample from 190 feet shows typical Ocala species. 
WELL NO. 3 OF THE PALMETTO PHOSPHATE COM¬ 
PANY, NEAR PIT NO. 1 ABOUT 2^ MILES 
NORTHWEST OF TIGER BAY, FLORIDA. 
A description of samples from this well has already been pub¬ 
lished (Florida Geological Survey, Seventh Annual Report, 1915, 
pp. 49,50). 
The. well was cased to a depth of 620 feet. Certain discrep¬ 
ancies between actual log records and apparent stratigraphic re¬ 
sults are given below. The examination of samples gives the fol¬ 
lowing results: 
30-300 feet. 
310 feet. 
330 feet. 
337 feet. 
350 feet. 
360-400 feet. 
410 feet. 
420 feet. 
450-530 feet. 
535 feet. 
540 feet. 
550 feet. 
560 feet. 
No foraminifera. 
Few poorly preserved foraminifera. 
Small fragments of Lepidocyclina. 
Small fragments of Lepido.cyclina. 
No Lepidocyclina noted. 
Abundant Lepidocyclina. 
Abundant Lepidocyclina and abundant Nummulites. 
Abundant Lepidocyclina and few Nummulites. 
Abundant Lepidocyclina and abundant Nummulites. 
Abundant Lepidocyclina and numerous Nummulites. 
Very few Lepidocyclina and numerous Nummulites. 
Brown crystalline calcite and whitish material with numerous 
Orbitolina. 
Mixed material evidently from above.
