90 FLORIDA GEOLOGICAL SURVEY-TWELFTH ANNUAL REPORT 
at the level at which drilling was proceeding at that time. Other 
forms of foraminifera occur with the Orbitolina, but none which 
stratigraphically could not have occurred with it. At 230, 240 and 
250 feet Miliolidae are frequent but are of types which may be of 
the same age as the Orbitolina. At 390 fee.t Tritaxia occurs with 
Orbitolina but as this genus is very characteristic of the Creta¬ 
ceous and found in the Lower Cretaceous it affirms the age of the 
Orbitolina. 
PROBABLE STRATIGRAPHY. 
The most striking fact of the upper part of the. well is the ap¬ 
parent absence of Lcpidocyclina limestone referable to either the 
Ocala or Vicksburg. In fact the genus Lepidocyclina is absent 
from the samples. 
All the. data from the samples at 115 feet and below indicate 
Comanchean Lower Cretaceous of the Fredericksburg group. 
The whole data would seem to indicate that the Lower Cre¬ 
taceous strata here come to within 115 feet of the. surface and 
that they are directly overlain by strata probably of Miocene age. 
This may indicate that the Ocala was eroded from this particular 
area or that the area was above water at that time and was an area 
of erosion rather than deposition. 
WELL OF L. E. MORROW, SANFORD, SEMINOLE 
COUNTY, FLORIDA. 
A description of samples from this well has already been pub¬ 
lished (Florida Geological Survey, Fifth Annual Report, 1913, 
p. 219). There is record of the casing of the. well to 100 feet. 
The samples I have had are four in number, as follows: 
95-100 feet. Water-worn fragments with black phosphatic pebbles and very- 
few worn fragments of Lepidocyclina. 
101-113 feet. Mostly calcite crystals. 
113 feet. Typical Ocala. Lepidocyclina , Operculina and Hetcrostcgina. 
113 plus feet. Similar to the preceding.
