AGE OF THE UNDERLYING ROCKS OF FLORIDA 
8/ 
160 feet. Numerous Orbitolina, arenaceous Bulimina, etc. 
200 feet. Abundant Orbitolina and like 160 feet. 
260-500 feet. Hard brownish rock without identifiable foraminifera. 
PROBABLE STRATIGRAPHY. 
As this well is known to start in the Ocala limestone, that for¬ 
mation with any surface overburden must have a total thickness 
of less than fifty feet. The horizon represented by large Num- 
mulites at 50 feet is Eocene similar to that noted at other wells 
and coming in below the Ocala. The samples from 75 and 100 
feet have a few of these Nummulites which have probably been 
carried down from the 50-foot level. At 110 feet the Lower Cre¬ 
taceous is entered and apparently continues to at least 200 feet, 
below which from 260-500 feet is a hard, brownish limestone seen 
in other wells, and represents the Fredericksburg or older forma¬ 
tions of the Lower Cretaceous. 
The Upper Eocene from the records seems to rest upon the 
Lower Cretaceous as in other areas. 
This is an especially important link in the evidence as confirm¬ 
ing the suspicion noted in the discussion of the Tiger Bay well 
that the Ocala there is really only represented by the forty feet 
of strata above the abundantly occurring Nummulites and that 
the material apparently coming below of Ocala age really was de¬ 
rived from 1 above. It would indicate that the Ocala limestone rep^ 
resented typically by the Lepidocyclina limestone about Ocala is 
usually but about 40 feet in thickness over a wide area and has 
not the great thickness that has been assigned to it. 
WELL OF J. WIGGINS AT EUSTIS, LAKE COUNTY, 
FLORIDA. 
Depth 180 feet, depth of casing not recorded, samples from 
100 to 180 feet. 
The samples from 100, 109, 115 and 120 feet show no for¬ 
aminifera. 
138 feet. Foraminifera are numerous, mainly Miliolidae with some large 
Rotaliidae.
