FULLER’S EARTH. 
The total production of fuller’s earth in the United States dur¬ 
ing 1916, as reported by the U. S. Geological Survey, was 67,822 
short tons, an increase over the preceding year of 19,921 tons. In 
addition to that produced there was imported into the United States 
during 1916, 15,001 short tons. Some fuller’s earth in former 
years has been exported from the United States, although the 
amount can not be determined owing to the fact that this product is 
not listed separately from other clays. 
The States producing fuller’s earth during 1915 were Arkansas, 
California, Florida, Georgia, Massachusetts and Texas. Of these 
Florida is the chief producer, the output from this State amounting 
to more than three-fourths of the whole output for the United 
States. The value of the fuller’s earth produced in the United 
States during 1916 was $706,951. 
The production in Florida, although not separately listed, is 
included in making up the total mineral production of the State. 
The following companies were engaged in mining fuller’s earth 
in Florida during 1916: The Floridin Company, Quincy and 
Jamieson; the Fuller’s Earth Company, Midway, and the Manatee 
Fuller’s Earth Corporation, Ellenton. 
ILMENITE AND MONAZITE. 
The minerals ilmenite and monazite have been produced to a 
limited extent for the first time in Florida during the past year. 
These minerals are obtained from the beach sand at Pablo Beach 
in Duval County. The firm operating there is Buckman and 
Pritchard. 
Ilmenite is a constituent of the sand on the Atlantic Beach as 
far south as Miami. It is found also very generally in the sands 
in the lake region of Florida, and is present to some extent through¬ 
out the State. The distribution of monazite is less well known, 
since it is present only in very small amounts, and is not detected 
in the sand except by a very careful examination.
