"The coming of iron manufacturers into the Indiana field should be encouraged. The reopening of ore deposits, the development of the coal fields, the building of furnaces within the state to smelt northern ores, the building of new railroads, and the extension of others, and the aggressive policy of existing roads to encourage industries along their lines, will undoubtedly make Indiana a great producer of iron and other products of commerce that will later be developed." So wrote C. W. Shannon in 1907, when In~iana was entering its third phase in the reduction of iron ore and in the manufacture of iron and steel. The U.S. Steel Corp. had recently purchased land at Indiana Harbor on Lake Michigan, and the new city of Gary was being laid out. Indiana was destined to become an iron- and steelproducing state again, and on a scale unheard of when the industry had its first start in the state. In the early part of the 19th century, farm implements and heavier household articles, such as kettles and stoves, were carried into the newly settled parts of Indiana by flatboat as far as the streams were navigable and then by wagon over trails that were difficult to travel even in good weather; therefore replacements for broken tools and utensils cost dearly. Early prospectors brought back to the East reports of abundant supplies of iron ore and plenty of timber to make charcoal. With these reports as a basis, several enterprising ironworkers set out for Indiana. Between 1835 and 1850 they built four blast furnaces and at least five Catalan forges (hearths for direct reduction of ore) to produce iron from the Indiana ores (fig. 1). After the Civil War several blast furnaces were designed to use Indiana Block coals. They reduced some local ore, but most of their ore was imported from Missouri.
