This is a history of the development of the harbor at Duluth, Minn., and Superior, Wis., into the most important bulk traffic port in the world. There is outlined the growth in traffic from the days of the early French explorer and fur trader to the present, with weekly shipments of more than 1,000,000 tons of iron ore.Construction of the harbor by the Corps of Engineers, Department of the Army, began in the days when there were still many wooden sailing vessels, which were loaded and unloaded by wheelbarrow and plank. Today, the harbor is being maintained and improved to accommodate the fast, deep draft, 600-ft-long, steel vessels with · enormous cargoes, which are loaded and unloaded at docks designed to accomplish this work quickly and efficiently by the most modern mechanic ally operated equipment.
