Fuller's earth from the Hymeson mine, 3 miles south of River Junction, the 
sample having been taken from the crusher at River Junction, Fla. This exerted 
only a moderate bleaching action on the cotton-seed oil, and would not bleach 
mineral oils very well. 
Mr. William Bruce states that there is fuller's earth halfway 
between River Junction and the Hymeson mine, near the top of the 
hill, and also near Rockbluff, back from the bluff, in the ravines 
among the hills. 
Mosquito Creek. — There is an exposure of fuller's earth on the south 
bank of Mosquito Creek, near the foot of a bluff, on land belonging 
to Mr. John D. McPhaul. The overburden is here too great for 
working. The deposit is along a small stream running north into 
Mosquito Creek in the NW. £ sec. 16, T. 3 N., R. 4 W. 
A section in the pit shows overburden (sand), 4 feet; fuller's earth, 
6 feet. The bed was not completely penetrated. 
The following is an analysis by Dr. Ileinrich Ries of fuller's earth 
from the NE. £ sec. 16, T. 3 N., R. 4 W., Gadsden County, Fla., from 
land of Mr. J. D. McPhaul:

Dr. Ries remarks: "As the moisture content of this sample was so 
large I have in the second column given the analysis with the moist- 
ure deducted and the percentages recalculated on the basis of the 
remainder being 100 per cent." 
The material was also exposed nearby in the bed of a crook. The 
slope down to the creek valley is gradual. A strip several hundred
