Boats with such a cargo set out from the lake ports of Duluth,SuPEKTOR, Ashland, and Marquette for manufacturing centres CENTRAL STATES 135 all along the lakes. As the ore must reach a point where coal iseasily obtained, it is taken to Chicago, Detroit, ClevelandBuffalo etc Notice how close to these cities the coal bedsextend (Fig. 248). The Lake Superior iron district is in three states, - MichiganWisconsin and Minnesota, the most important being Michigan(J^ig. 250), and the least important Wisconsin. These three statestogether produce seventeen times as much ore as sudden development of mining in this region has brought sorimny people that numerous towns and cities have grown up: butthe lack of coal has prevented much iron manufacturing. ve
