To these six ports of the Northland come the vikings of the Lakes and their immense fleets. Four of these ports are within a radius of seventy-five miles, and the two others, in Michigan, are about one hundred and fifty miles farther east and south. No other area of lake or ocean in the world is as much travelled by shipping as that along which these ore harbours are situated. The people of Duluth have witnessed blockades of vessels such as have never been seen in the greatest ocean ports. Over this part of Superior there is a constant trail of smoke from the funnels of ships. During one month there were 1221 arrivals and clearances from Duluth alone, an average of forty a day. [Illustration: Steamers at a Modern Ore Unloading Plant at Conneaut.] Behind these great ships, which rest never a day nor an hour for eight months of the year, are the kings of Lake commerce--such men as J. C. Gilchrist, James Davidson, Captain Mitchell, William Livingstone, Harry Coulby, W. C. Richardson, A. B. Wolvin, G. Ashley Tomlinson, and scores of others. To write of these would be to chronicle a history of men who have fought their way to the top through sheer force of the “breed that is in them.” Take G. Ashley Tomlinson, of Duluth, for instance, whose ships carry a couple of million tons of ore a year. “Not a great record,” as Mr. Tomlinson modestly says, but still enough to supply every man, woman, and child in the United States with a little matter of fifty pounds each twelvemonth! In a novel Tomlinson would make an ideal soldier of fortune; in plain, matter-of-fact life he represents those elements which make the great men of the Lakes. He is forty years old. He has sixteen ships. His income is over one hundred and fifty thousand dollars a year.
