A Metal-working Age.
Nearly every industry depends to some extent, and most industries depend to a very great extent, upon metal working, either by employing metal workers directly in some processes, or by using metal products as raw materials in the manufacture of other products, or at least by using tools, implements, machines, and engines, which are products of metal-working trades and industries. And, in addition, these trades and industries produce a great variety of finished utensils and furniture ready for consumption in households. More than any other ours is a metal-working age.
