QUANTITY PRODUCED.-This factory produces 4000 pounds of "mineral wool" per day. It is made out of iron ore unfit for any other purpose. This is the only establishment of the
kind in the State; there being only one other in the United States. The wool, after manufacture, has the appearance of cotton, for which, without a close inspection, it would be taken.
Fire will not burn it; and it meets with a ready sale, being used in upholstery, the rubber business, &c.
