The state's leading crops are cotton, soybeans, and tobacco; cattle, dairy products, and hogs are also principal farm commodities. Tennessee's leading mineral, in dollar value, is stone; zinc ranks second (Tennessee leads the nation in its production). Industry is being continually diversified; the state's leading manufactures are chemicals and related products, foods, electrical machinery, primary metals, automobiles, textiles and apparel, and stone, clay, and glass items. Aluminum production has been important since World War I.   *Columbia Encyclopedia, Sixth Edition, Copyright (c) 2003
