contain quicksilver about four years since, during
perimenis made by some Mexcsns TO sme the ore for
the purpose OF obtaining 9oid which they supposed
10 contain. Several attempts since, to work the mine
have proved futile until recently Mr. Forbes Of the
firm Of Barron Forbes Co having the present charge
of the entire operations, wished to devise some way Of
extracting the metal without mixing hme with the ore

was burned and mingled with this, the ores yield
vastly larger per cenage OF metal In the last three
weeks Says Mr. about 10 900 pounds of metal have
been cted with the same appsraus being yield
OF over fifty per cent. Between 1900 and 10000
pounds have been extracted In about tHo months only
six miners having been employed in digging the ore,
and the hands of the establishment all tOd miners,
furnace wood choppers, &c. &c. numbering only
score. The mine is probably yielding net proht OF
100000 year with its present crude apparatus.
With suitable furnaces and iron cylinders or retors
the mine would easily yield 81 100000 and upward
