The only section of the world that ap-proaches it is in Eussia near the Caspian Sea. The oil business, which isone of the great industries of the country, is in the hands of the StandardOil Company, which has absorbed a large number of the small the wells the oil is led to the refineries in pipes many miles long, and.

Iron Ore. — Pennsylvania and West Virginia enjoy a great advan-tage in having within their own borders an abundance, not only ofcoal, but also of oil and gas for fuel. Iron ore is also found in Penn-sylvania, Virginia, and other states. Thus both the raw material andthe fuel necessary for manufacturing it into useful articles are foundalmost side by side. Of course the cities of the neighboring states, suchas New York and New Jersey, are also able to obtain these materials. This is very important, since iron is the most valuable metal for manu-facturing that exists. Like coal, this iron ore was prepared long ago,though in a very different manner, as follows. Small quantities of ironexist in many minerals and rocks
