88 FLORIDA GEOLOGICAL SURVEY-TWELFTH ANNUAL REPORT 
160 feet. Similar foraminifera, but with occasional specimens of Orbitolina of 
the high conical form. 
170 feet. Similar with occasional large Nummulites. 
180 feet, Similar but without Nummulites. 
PROBABLE STRATIGRAPHY. 
As the upper 120 feet is not represented by samples, nothing 
definite can be. given except that the occurrence of the large Num¬ 
mulites at 170 feet is a clear indication that they came originally 
from somewhere above 138 feet. Above the nummulite horizon 
may be the Upper Ocala, but there are no traces of Lepidocyclina 
in any of the samples, so if the Ocala had been penetrated it must 
have been securely cased in and all the material removed before 
any of the samples below 100 feet were taken. The thickness of 
the Ocala, if it occurred, cannot have been very great. 
The occurrence of Orbitolina and the group of smaller fo¬ 
raminifera characteristic of the Apopka well at levels of 115 feet 
show the slightly lower level of the Lower Cretaceous than further 
south. 
WELL OF DUNDEE PETROLEUM COMPANY AT BUSH- 
NELL, SUMTER COUNTY, FLORIDA. 
Depth of well 3,080 feet. Depth of casing not recorded. Sam¬ 
ples begin at 380- foot level. 
Although the samples of this well represent every five or ten 
feet of the borings they are as a whole very disappointing in the 
information they give. From 380 to 500 feet the samples show a 
hard, granular limestone apparently equivalent to that from 260-500 
feet in the well at Anthony. If this is the case, the Ocala and 
Orbitolina horizons of the Lower Cretaceous had already been pen¬ 
etrated before, the 380-foot level where samples are available. 
500-664 feet. 
684-867 feet. 
890 feet. 
900-1008 feet. 
1027 feet. 
Mostly hard, brownish limestone with no foraminifera. 
Granular limestone with variable amounts of dark flint chips. 
No foraminifera. 
Same material with a fragment of Orbitolina. 
Same material. No foraminifera. 
Same material. Cast of foraminifera.
