Canada is the child of the sea. Her infancy was cradled by her waterways; and the life-blood of her youth was drawn from oceans, lakes, and rivers. No other land of equal area has ever been so intimately bound up with the changing fortunes of all its different waters, coast and inland, salt and fresh. The St Lawrence basin by itself is a thing to marvel at, for its mere stupendous size alone. Its mouth and estuary are both so vast that their salt waters far exceed those of all other river systems put together. Its tide runs farther in from the Atlantic than any.
