"The first view, six hundred miles from the lake, filled me with astonishment and admiration,--nearly half a mile broad, flowing with a swift current, and still I was three hundred and fifty miles from the mountains." The small steamer now plying on the Red River might, during the season of high water, make its way from Fort Abercrombie down this river, then through Lake Winnipeg, and up the Saskatchawan westward to the base of the Rocky Mountains,--a distance altogether of sixteen hundred miles. We are in the latitude of the continental water-system. If we travel along the parallel eastward, one hundred miles will bring us to the Mississippi at Crow Wing, another hundred will take us to Lake Superior, where we may embark on a propeller of five hundred tons and make our way down through the lakes and the St. Lawrence to Liverpool, or any other foreign port; or travelling west three hundred miles will bring us to the Missouri, where we may take one of the steamers plying on that stream and go up to Fort Benton under the shadow of the Rocky Mountains. Two hundred and fifty miles farther by land, through the mining region of Montana, will bring us to the navigable waters of the Columbia, down which we may glide to the Pacific. Nowhere in the Eastern hemisphere is there such a succession of lakes and navigable rivers, and no other country exhibits such an area of arable land so intersected by fresh-water streams. It would be an easy matter by canals to connect the Red River, the Saskatchawan, and Lake Winnipeg with the Mississippi. We can take a canoe from this point and paddle up to Otter-Tail Lake, and there, by carrying it a mile or so over a sand-ridge, launch it on Leaf River, an affluent of the Crow-Wing, and so reach the Father of Waters. We may do even better than that. Instead of paddling up stream we may float down with the current a few miles to the outlet of Lake Traverse, row across the lake, and from that into Big Stone Lake, which is the source of the Minnesota River, and by this route reach the Mississippi below Minneapolis. Boats carrying two tons have frequently passed from one river to the other during the season of high water. It would not be difficult to construct a canal by which steamers might pass from the Mississippi to the base of the Rocky Mountains in British Columbia. Railroads are superseding canals, and it is not likely that any such improvement of the water-way will be attempted during the present generation. But a glance at the river and lake systems enables us to obtain a view of the physical features of the country. We see that the northwestern portion of the continent is an extended plain. The Red River here by our encampment is about nine hundred and sixty feet above the sea. If we were to float down to Lake Winnipeg, we should find that sheet of water three hundred feet lower.
