For this reason, I am adding to my preceding chapters a brief history of the Lakes. It is not what might be called a history in detail, for such a story of the Inland Seas would fill volumes in itself. No other portion of the globe has been fraught with more incident of historical and romantic interest than these fresh-water heritages of our nation. The dramas that have been played upon them or along their shores would fill libraries. Their unrevealed pages of romance and tragedy would furnish rich material for the writers of a century. About them lie the dust of three quarters of the aboriginal inhabitants of North America. Along their shores were fought some of the world’s most relentless wars of absolute extermination. Upon their waters occurred the most romantic adventures of the early exploration of the continent. Every mile of these waters, now clouded with the smoke of a gigantic commerce, is fraught with the deepest historical interest. And yet, as I write this, there comes to my mind a thought of those countless thousands of Americans who, travelling afar for their pleasures, seek in every quarter of the globe that their feet may tread in awesome respect upon spots hallowed because of their historical associations, whether those associations be of fact, of legend, or of song. The romance of the Lakes does not begin with their early discoverers; neither does it begin with the primitive inhabitants along their shores. It dawns with their making. Unnumbered thousands of years ago, before the glaciers of the Ice Age crept over the continent; when prehistoric monsters, still living in a tropical world, roamed throughout what is now the Lake region; and when man, if he existed at all, was in his crudest form, the Great Lakes were still unborn. Where their ninety-five thousand square miles of surface now afford the world’s greatest highways of water commerce there were then vast areas of plain, of highland and plateau, rising at times to the eminence of mountains. Those were the days when the North American continent was completing itself, when the last handiwork in the creation of a world was in progress. In place of the Lakes there were then a number of great rivers in these regions--rivers, which despite the passing of ages, have left their channels and their marks to this day. These rivers were all of one system and were all tributary to one great stream, the Laurentian River, whose channel to the sea was that of the St. Lawrence of to-day. Were it possible for one to conceive himself back in those primitive times a journey over this first great river system of the continent would have carried him, first of all, from the still unfinished ocean along the south shore of what is now Lake Ontario. He would have travelled within ten miles of where scores of towns and cities now flourish, and almost directly opposite what is now the Niagara River he would have encountered another great stream pouring into the Laurentian from the south and
