SECOND ANNUAL REPORT—STRATIGRAPHIC GEOLOGY. 99 
by . Mr. Rosendale. The overburden is about 6 feet, and there are about 8 feet 
of fullers earth. The writer was not able to get fresh specimens, hence pieces 
from the dump were selected. The land lies rather flat, along a small creek 
running into the Ocklocknee River. 
A section on the Seaboard Air Line Railway, about 1 mile east of Talla¬ 
hassee, at milepost 163, shows the following exposures: 
Section on Seaboard Air Line Railzmy. 
3. The upper 25 or 30 feet at the ends of the cut are reddish, 
yellowish sands. 
2. Sands with clay partings .. 5 to 10 feet. 
1. Whitish or bluish clay resembling fullers earth in thin laminae 
with sand partings ..... 4 to 5 feet. 
In a curve in the railroad track between mileposts 163 and 164 is another 
cut between 15 and 20 feet deep, and the same section as above described was 
again seen. The clay at the base resembles more closely fullers earth than in 
the first described section. It contains less sand. 
A fullers earth horizon is also mentioned in the Jackson’s Bluff 
section, which is included under the discussion of the Miocene. 
On the bank of the Ocklocknee River, one mile north of Holland 
postoffice, there is an exposure of hard light-gray limestone which 
was formerly quarried. The surface is now almost obscured by debris, 
but it is still possible to find small exposures which indicate that the 
beds are at least twelve feet thick. The upper four feet contains many 
specimens of Carolia floridana Dali, but the remainder of the outcrop 
is conglomeratic and appears to be almost destitute of fossils. 
The following record of a well sunk by Mr. J. A. Henderson near 
the western limits of Tallahassee, was furnished by Vaughan : 1 
2. Sands and clays . 25 feet. 
1. Limestone containing clay layers . 75 feet. 
The limestone furnished Ostrea rugifera Dali, Pecten chipolanus 
Dali, Anomia sp. 
On Rouse’s Mill Creek, near West Sopchoppy, there is an ex¬ 
posure of about ten feet of soft light-gray sandstone. This rock is 
friable and resembles the Alum Bluff formation in texture. A few 
fossils occur in the sandstone, but they are too friable to obtain good 
specimens, only one identifiable specimen of Pecten madisonius var. 
sayanus Dali having been obtained. 
At West Sopchoppy there is a bed of very fossiliferous marl which 
probably lies stratigraphically above the soft sandstone at the mill. 
The marl contains some material like that at the mill, but is much 
more calcareous and contains many shells. The thickness of the out¬ 
crop is about ten feet, but the base of the marl is not exposed, and
