As settlement went on and Canada developed westwards along this unrivalled waterway man tried to complete for his civilized wants what nature had so well provided for his savage needs. There is a rise of six hundred feet between Lake St Peter and Lake Superior. So canals were begun early in the nineteenth century and gradually built farther and farther west, at a total cost of $125,000,000, till, by the end of the century, with the opening of the Canadian 'Soo,' the last artificial link was finished and direct navigation was established between the western end of Lake { 4} Superior at Duluth and the eastern end of the St Lawrence system at Belle Isle, a distance of no less than 2340 miles.
But even the mighty St Lawrence, with the far-reaching network of its connecting systems, is not the whole of Canada's waters. The eastern coast of Nova Scotia is washed by the Atlantic, and the whole length of British Columbia by the Pacific. Then, there are harbours, fiords, lakes, and navigable rivers not directly connected with either of these coasts or with the wonderfully ramified St Lawrence. So, taking every factor of size and significance into consideration, it seems almost impossible to exaggerate the magnitude of the influence which waterways have always exerted, and are still exerting, on the destinies of Canada.
Canada touches only one country by land. She is separated from every other foreign country and joined to every other part of the British Empire by the sea alone. Her land frontier is long and has given cause for much dispute in times of crisis. But her water frontiers--her river, lake, and ocean frontiers--have exercised diplomacy and threatened complications with almost constant persistence from the first. There were conflicting rights, claims, and jurisdictions about the waters long { 5} before the Dominion was ever thought of. Discovery, exploration, pioneering, trade, and fisheries, all originated questions which, involving mercantile sea-power, ultimately turned on naval sea-power and were settled by the sword. Each rival was forced to hold his own at sea or give up the contest. Even in time of peace there was incessant friction along the many troublous frontiers of the sea. From the Treaty of Utrecht in 1713 down to the final award at The Hague, nearly two centuries later, the diplomatic war went steadily on. It is true that the fishing grounds of Newfoundland were the chief object of contention. But Canada and Newfoundland are so closely connected by geographical, imperial, and maritime bonds that no just account of craft and waterways can be given if any attempt is made to separate such complementary parts of British North America. They will therefore be treated as one throughout the present book.
