izontal beds, and is easily and cheaply
mined and extracted. At an exper-
mental trial of the works lately made
several tons of regulus were procured
and shipped to New York, and the
quality is said to be superior to the
best imported metal. This is &C
counted for by the phenomenal pu-
rity OF the ore, containing as it does
