ing cottonseed oil, while that of Massachusetts is reported as being 

 used in fulling woolen goods. The fullers earth of California is 

 used according to the State Mineralogist principally as a clarifying 

 agent in the refining of crude oils, 



PRODUCTION OF FULLERS EARTH IN THE UNITED STATES. 



Florida is the chief producer of fullers earth in the United 

 States. The deposits being worked are those of Gadsden County 

 in northern Florida, and of Manatee County in southern Florida, 

 the earth being found at both localities in the Alum Bluff forma- 

 tion of Upper Oligocene age. The following companies reported 

 production of fullers earth in Florida during 191 3: The Atlantic 

 Refining Company, Ellenton; the Floridin Company, Quincy; the 

 Fullers Earth Company, Midway. In addition to these the Mana- 

 tee Fullers Earth Company, Ellenton, is reported as expecting to 

 operate during 1914. 



The total production of fullers earth in the United States 

 during 19 13 was 38,594 short tons, valued at $369,750, being an 

 increase both in quantity and value over that of the preceding 

 year*. In addition to that produced, there was imported into 

 the United States during the year ending June 30,1913,16,866.16 

 tons, of which 1,597 tons valued at $10,359 were unmanufactured 

 or unground, while 15,269.16 tons valued at $135,229 were manu- 

 factured or ground. These importations were under the old rate 

 of duty, which was $1.50 per ton for the unmanufactured earth, 

 and $3.00 per ton for the manufactured product. During the 

 last half of 1913, July i to December 31, under the new tariff 

 rates, which are for unmanufactured earth 75 cents per ton, and 

 for manufactured $1.50 per ton, there was imported 974 tons un- 

 manufactured valued at $7,660 and 7,613 tons manufactured earth 

 valued at $68,558. These valuations are based on the wholesale 

 price of the product at the port of origin. The actual cost to the 

 consumer includes freight and commission in addition. The ex- 

 ports of fullers earth from the United States cannot be determined 

 owing to the fact that this product is not listed separate from 

 other clays.
