Nails
Formerly all nails were made by hand or forged on the anvil, and large quantities are still produced in this manner in England and other parts of Europe. Nail-making by machinery was originated in Massachusetts in 1810. At present we have machine wrought-nails, cut-nails, and cast-nails. The machine cut-nails are simply wedge-like in breadth, equal in thickness--head and body--to the sheet iron from which they are cut, and these are always to be preferred for strengthening and securing the sand surfaces of moulds, rather than those which have had heads forged on them. The length of iron machine cut-nails and the number contained in a pound will be found in the following table:
