Vast as is the accumulation of fresh water in Lake Superior, the area of the country which it drains is limited enough. Fifty miles from its northern shores the rugged hills which form the backbone or “divide” of the continent raise their barren heads, and the streams carry from thence the vast rainfall of this region into the Bay of Hudson. Thus, when the voyageur has paddled, tracked, poled, and carried his canoe up any of the many rivers which rush like mountain torrents into Lake Superior from the north, he reaches the height of land between the Atlantic Ocean and Hudson Bay. Here, at an elevation of 1500 feet above the sea level, and of 900 above Lake Superior, he launches his canoe upon water flowing north and west; then he has before him hundreds of miles of quiet-lying lake, of wildly rushing river, of rock-broken rapid, of foaming cataract, but through it all runs ever towards the north the ocean-seeking current. As later on we shall see many and many a mile of this wilderness—living in it, eating in it, sleeping in it-although reaching it from a different direction altogether from the one spoken of now, I anticipate, by alluding to it here, only as illustrating the track of the Expedition between Lake Superior and Red River. For myself, my route was to be altogether a different one. I was to follow the lines of railroad which ran-out into the frontier territories of the United States, then, leaving the iron horse, I was to make my way to the settlements on the west shore of Lake Superior, and from thence to work Round to the American boundary-line at Pembina on the Red River; so far through American territory, and with distinct and definite instructions; after
