“ochres. 
“There are quite aibundant deposits in the S'tate of a kind of iron ores 
that are usually called ochres. They are characterized by being easily 
pulverized, soft to the touch, and freedom from grit, and by their con- 
taining considerable quantities of alumina. They find considerable use 
in the preparation of the so-called mineral paints, and are quite valuable 
for such and lOther purposes.” 
Analyses are given of ochres from Northwest Texas and Central Texas.
