FULLERS EARTH. 
Florida is the chief producer of fullers earth in the United 
States, more than 7g% of the total production during 1917 being 
credited to that State. The production in Florida, although not 
separately listed, is included in making up the total mineral pro- 
duction of the State. The fullers earth of Florida is used chiefly 
in clarifying mineral oils, although some is being prepared also 
for vegetable oils. 
The following companies are engaged in mining fullers earth 
in Florida: The Atlantic Refining Company, Ellenton; The 
Floridin Company, Quincy and Jamieson; The Fullers Earth 
Company, Midway, and the Manatee Fullers Earth Corporation, 
Ellenton. 
ILMENITE. 
The production of ilmenite from the beach sands at Pablo 
Beach which was begun in 1916 was continued during 1917. Dur- 
ing the year the plant was somewhat enlarged and was connected 
with the Florida East Coast railway by a side track. With the 
ilmenite is associated, aside from quartz sand, a considerable num- 
ber of other minerals.* The company operating at this place is 
Buckman & Pritchard/Pablo Beach. 
PEAT. 
Peat is being produced in Beswick, Florida, by the Robert 
Ranson Company. This being the only plant in operation in the 
State, the production is not separately listed. The peat produced 
by this company is placed on the market in the form of prepared 
humus and peat litter.
