MINERAL INDUSTRIES. 
BRICK-MAKING CLAYS. 
A good quality of common building brick is made from the 
clay in this area. Two brick-making plants, the Ocklocknee Brick 
Company and the Tallahassee Pressed Brick Company, are located 
in the eastern part of Gadsden county, the former on the Georgia, 
Florida and Alabama railway, the latter on the Seaboard Air Line, 
railway. Both plants are near the Ocklocknee river and use a 
clay taken from the river valley. 
FULLERS EARTH. 
Fullers earth was first discovered in Florida near Quincy, 
Gadsden county, in 1893.* The industry has steadily grown until 
at the present time the largest and best equipped plants in the coun- 
try are located in this county, which is the leading county of Flor- 
ida in the production of this clay. According to statistics, Florida 
produces approximately three-fourths of the fullers earth of the 
United States, and of this amount Gadsden county produces more 
than half. 
The Floridin Company, with mines at Quincy and at Jamieson, 
operates two of the largest and best equipped mines and plants in
