Not long ago, I was on a Lake freighter pounding her way up Huron on the “thousand-mile highway” that leads to Duluth. Beside me was a man who had climbed from poverty to millions. He was riding in his own ship. His interests burned ten thousand tons of coal a year. He was one of the ore kings of the North--as rough as the iron he dug, filled to the brim with enthusiasm and animal energy of the Lake breed; a man who had helped to make the Lakes what they are, as scores of others like him have done. Before and behind us there trailed the smoke of a dozen of the steel leviathans of the Inland Seas. I had asked him a question, and there was the fire of a great pride in his eyes when he answered. “It would make a nation by itself--this Lake country!” he said. “And it would be America. It’s America from Buffalo to Duluth, every inch of it, and the people who are in it are Americans. That’s American smoke you see off there, and American ships are making it; they’re run by a thousand or more American captains, and they’re Americans fore ’n’ aft, too. We’ve got only eight States along the Lakes, but if we should secede to-morrow the world would find us the heart and power of the nation. That’s how American we are!” This is the patriotism one finds in the Lake country, from the roaring furnaces of the East to the vast ore beds of Minnesota. It is representative of the spirit that rules the Inland Seas; it is this spirit that has built an empire, and is building a vaster empire to-day, along the edges of the world’s greatest fresh-water highways. [Illustration: The First Step in the Making of a Ship--Laying the “Keel Blocks.”] With more than thirty-four millions of people living in the States bordering on them, possessing one third of the total tonnage of North America, and saving to the people of the United States five hundred million dollars each year, or six dollars for every man, woman, and child in the country, one of the most inexplainable mysteries of the century exists in the fact that the Great Lakes of to-day are as little known to the vast majority of Americans as they were a quarter of a century ago. While revolutions have been working in almost all lines of industry, while States have been made and cities born, America’s great Inland Seas have remained unwatched and unknown except by a comparative few. Upon them have grown the greatest industries of the nation, yet the national ignorance concerning them can hardly find a parallel in history. Were they to disappear to-morrow the industrial supremacy of the republic would receive a blow from which it could never recover. The steel industry, as a dominant commercial factor, would almost cease to exist. One half of the total population of the country would be seriously affected, and America would fall far behind in the commercial race of the nations.
