FULLER'S EARTH DEPOSITS OF FLORIDA AND GEORGIA. 
By T. Wayland Vaughan. 
INTRODUCTION. 
The first fuller's earth discovered in the United States was at 
Quincy, Fla., in 1893. Since 1896 details regarding new occurrences 
have annually appeared in the volume on Mineral Resources, pub- 
lished by the United States Geological Survey. A discussion of the 
Florida and Georgia deposits is given in the present paper. 
Extensive deposits of fuller's earth occur in Decatur County, Ga., 
and in Gadsden, Leon, and Alachua counties, Fla. With the excep- 
tion of the Alachua County deposits, they are all of Upper Oligocene 
age, and equivalent with the Alum Bluff beds. 
DECATUR COUNTY, GA. 
Lester property near Attapulgus. — The material occurs in the south- 
ern and eastern slopes of the hills 1± miles west of Attapulgus, where 
Mr. J. D. Lester has sunk ten pits, nine of them being on the south 
side of the road from Attapulgus to Faceville, and on the west side 
of Sanborn (or Little Attapulgus) Creek, and the remaining one on 
the east side of that creek. Martin Mill Creek runs east across the 
area in which the nine pits have been dug, and cuts below the level 
of the f uller's-earth stratum. Three of the prospects are on the north 
side of the creek, and six are on the south side. The first three extend 
from the road to the creek. The distance between the outer prospects 
is about 700 yards. The distance across the prospects on the south 
side of the creek is about 400 yards. Fuller's earth was encountered 
in all the prospects. The thickness on the north side of the creek 
at the foot of the hill was 2^ feet; on the south side it varies from 3 
to 9 feet.
