FLORIDA STATE GEOLOGICAL SURVEY. 
3. White argillaceous sandstone containing fossils... .. 5 feet. 
2. Fullers earth.,. 9 feet. 
1. Soft sandstone, sand, and fullers earth.... 15 feet. 
It is estimated that there are about 10,000 tons to the acre. The mine was 
visited in company with Mr. Ward. About 2 acres have been mined, and 20,000 
tons were taken out. Mr. Ward states that operations were begun in 1895, and 
closed down in December, 1899, because the Standard Oil Company had sufficient 
earth on hand for the present. Bed No. 3 contains numerous poor fossils. 
Several species were collected, of which the following is a list. 
List of fossils collected from fullers earth mine of Chesebrough Manufac¬ 
turing Company, near Quincy, Florida : 
Cypraea, agreeing in form and size 
with C. pinguis Conrad from the 
Chipola horizon. 
Murex mississippiensis Conrad? var. 
Fnigur spiniger Conrad? 
Modulus sp. 
These fossils indicate an upper Oligocene horizon, corresponding strati- 
graphically with No. 3 of Dali and Stanley-Brown’s Rock Bluff section, which 
was given on a preceding page. 
A specimen of Carolia floridana Dali, from the fullers earth horizon at 
Quincy, is in the United States National Museum. This is considered an index 
fossil of our upper Oligocene. 
An examination of the section at the Owl Commercial Company’s mine dis¬ 
closed the following exposures :

1. Fullers earth ...... 
The mining is done by stripping. 
Fullers earth occurs along Quincy Creek above the Owl Commercial Com¬ 
pany’s works, about l l / 2 miles west of Quincy, on land belonging to Mr. William 
Bruce in Sec. 12, T. 2 N., R. 4 W. A specimen taken from an auger bore was 
donated by Mr. Bruce. The overburden along the creek flat is 4 or 5 feet thick. 
Mr. Bruce also donated some pieces of the material which came from a pit 
that is at present filled with water. A pit has also been dug in Sec. 2, T. 2 N., 
R. 4 W., on land belonging to Messrs. Taussig and Wedeles. Some pieces were 
picked up out of the dump around this hole. The overburden is from 4 to 5 
feet thick, the same as on Mr. Bruce’s land. 
The fullers earth in these localities has not been thoroughly explored. It 
seems to be of good quality, the overburden is not great, and the land is flat. 
Transportation by railroad is within one-half to three-fourths of a mile. From 
what Mr. Bruce says, the deposit is thick enough for profitable working—about 
8 feet. 
LEON COUNTY. 
Twelve miles west of Tallahassee, on property belonging to Messrs. W. H. 
Allen and Sons, are occurrences of fullers earth. Several pits have been sunk 
5 to 20 feet. 
6 to 10 feet. 
3 to 4 feet. 
5 to 6 feet.
