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. But, even apart from Newfoundland, the Canadian interests concerned rather with the water than the land make a most remarkable total. They include questions of international waterways and water-power, salt and fresh water fishing, sealing, whaling, inland {6} navigation, naval armaments on the Great Lakes, canals, drainage, and many more. The British ambassador who left Washington in 1913 declared officially that most of his attention had been devoted to Canadian affairs; and most of these Canadian affairs were connected with the water. Nor was there anything new in this, or in its implication that Canadian waters brought Canada into touch with international questions, whether she wished it or not. The French shore of Newfoundland; the _Alabama_ claims; the San Juan boundary; the whole purport of the Treaty of Washington in 1871; the _Trent_ affair of ten years earlier; the Panama Canal tolls of to-day; the War of 1812; the war which others called the Seven Years' War, but which contemporary England called the 'Maritime War'; all the invasions of Canada, all the trade with the Indians, all Spanish, French, Dutch, British, and American complications--everything, in fact, which helped to shape Canadian destinies--were inevitably connected with the sea; and, more often than not, were considered and settled mainly as a part of what those prescient pioneers of oversea dominion, the great Elizabethan statesmen, always used to call 'the sea affair.' {7}
