IRON SAND.
A valuable iron ore, in the form of black sand, exists in large deposits on the east beach of Block Island, R.I. D. C. M'Cotter uses it in making steel. New processes and a machine for separating the iron from the sand have been invented, which clear 100 tons of sand in ten hours. The separation is done by magnets. As the mineral ore pours out of the chutes it is placed in bags, each holding 1121b, and shipped to Hoboken, and thence to Rockaway, N.J. There it is loaded on waggons and afterward taken to the furnace. It is mixed with charcoal, taken by elevator into the hopper, and distributed into sixteen large cylinders holding about ten tons, and heated to a red heat ; then it is tapped at the bottom and let down into a large oven still kept at a red heat, and there burns out all the charcoal. The iron doors are opened, the sand is hauled out into a large charcoal fire, and forms a mass which is hammered by large steam* hammers into blooms, weighing from 200 to 3001 bs.
