Value of a bar of iron.
--A bar of iron, originally valued at five dollars, is worth, when worked into horseshoes, ten dollars and fifty cents; into needles, three hundred and fifty-five dollars; into pen-knife blades, three thousand two hundred and eighty-five dollars; into shirt-buttons, twenty-nine thousand four hundred and eighty dollars; into balance-springs of watches, two hundred and fifty thousand dollars! Thirty-one pounds of iron have been made into wire upwards of one hundred and eleven miles in length, and so fine was the fabric that part of it was converted, in lieu of horse-hair, into a barrister's wig.
