the land of Mr. J. D. McPhaul, NE. £ sec. 16, T. 3 N,R.4W, Gads- 
den Comity, Fla. These two samples, when tested with cotton-seed 
oil, were found to bleach it as well as the Sumter material which was 
prepared and sent to Charleston. When tested with crude petroleum 
it was found not to bleach it quite so well as the original Quincy 
material. 
Ries states that the Sumter (S. C.) material bleached cotton-seed 
oil as well as English earth, and bleached petroleum practically as 
well as that from Quincy. 
Colin property near Attapulgus. — On Messrs. Colin & Co.'s prop- 
erty fuller's earth occurs at a point 2 miles east of Mr. Getzlow's 
house. It is overlain by a few inches of soil and 2^ feet of cAay, and 
is at least 4 feet thick. 
Fuller's earth also occurs on land in the NE. i sec. 8, and E. | sec. 
0, T. 3 N., R. 3 W., in Florida. Mr. Mark W. Munroe is interested in 
this property and in lots in Georgia. 
GADSDEN COUNTY, FLA. 
Near River Junction. — Four miles southeast of River Junction is 
the mine formerly worked by Mr. Ilymeson.

3. Stiff blue clay, the top of the fuller's earth deposit 4 
2. Fuller's earth. A considerable amount of the overburden had been thrown 
off, but due to weathering and wash there is no really good exposure. 
Judging from what can now be seen, according to a roughly leveled sec- 
tion, ifc seems that the deposit is at least 8 feet thick, and it may be thicker. 
There is no means of determining its horizontal extent. A box of the 
earth was collected from the best exposure.

The rocks beneath the Chattahoochee formation are not exposed near River 
Junction. 
The inference from this section apparently would be that the Chat- 
tahoochee limestone is 88+ feet in thickness, separated by 17 feet of 
unexposed strata from the deposit of fuller's earth, which would come 
above. This would stratigraphieaHy correlate the deposit of fuller's 
earth with the Alum Bluff beds. 
Dr. H. Ries analyzed and tested fuller's earth from this property, 
with the following results:
