SECOND ANNUAL REPORT-STRATIGRAPHIC GEOLOGY.

After summarizing the results of previous investigations, Dali 1 
mentions the following new localities where the Ocala limestone is 
exposed: 
Since then Mr. Willcox has obtained the rock in place 15 miles northeast 
of the original locality, from the shore of Wacassassa Bay, near Cedar Key, 
and also from the banks of the Wacassassa River, Levy County; from a “sink¬ 
hole” at Pemberton’s Ferry 2 on the Withlacoochee River; about 10 miles east¬ 
ward from Brooksville and also at Bayport, Hernando County, and at various 
places about Ocala. Prof. Wetherby has also sent specimens from a well 5 
miles southwest of Gainesville, Alachua County, and Mr. L. C. Johnson reports 
it from an old Confederate iron furnace, 3 miles north of Levyville, Levy 
County, where it is only 20 feet thick and is covered with a bed of bog-iron ore 
formerly worked. Pemberton’s Ferry is the most southern point at which it 
has been recognized at the surface, but at Bartow, Polk County, it occurs 
covered by about 6 feet of later strata. 
From the character of its included organic remains the exposure 
at Martin Station 3 is regarded as equivalent to the Ocala limestone. 
At this locality, the rock is more or less silicified and hence has been 
found useful for railroad ballast, road metal and other purposes where 
durable material is needed. 
To the rock at the old Confederate iron works in Levy County, 
Mr. Johnson 4 gave the name “Levyville formation/' and states that it 
consists of about twenty feet of soft, porous building stone. He be¬ 
lieved that it has been partially removed by erosion in the western part 
of the peninsula where it is much thinner than farther east. He also 
expressed doubt as to its ever having been deposited over the entire 
surface of the underlying- Vicksburg. 
Several other localities were mentioned where this formation was 
recognized, among them being Payne’s Prairie. At a quarry on the 
Newnanville road near the Santa Fe River, Johnson reports that the 
Neocene formations rest directly upon the limestone of Vicksburg age 
the nummulitic rock (Ocala) being absent. Johnson’s Levyville form¬ 
ation has usually been regarded as the substantial equivalent of the 
Ocala limestone; but it is not possible at the present time to verify 
the determination of the nummulites, and the rocks at Levyville may 
really belong to some other formation. 
In 1902 Miss Maury 5 summarized the known distribution of the 
Ocala limestone, but did not give any new information relating to it.
