The line from Duluth to Brainerd follows, for many miles, the winding valley of the St. Louis river, through scenery for the most part stern and wild, yet not without an occasional suggestion of the gentler beauty of the far-off Youghiogheny. Between Fond du Lac and Thompson the river has a descent of 500 feet in a distance of twelve miles, tearing its way with terrific force through a tortuous, rock-bound channel. The best point for observing the fine effect of these impetuous rapids and cascades, known locally as the Dalles of the St. Louis, is near the twentieth mile post westward from Duluth. Pursuing its way in the direction of Brainerd, the train traverses a country comparatively little known. Its scanty population is engaged almost entirely in logging, lumber manufacturing, and hunting, the immense forest covering the face of the country abounding with deer, bear, wolves, foxes and other game. Emerging from the deep recesses of the forest, and passing swiftly through the lake region already referred to, we find ourselves in a level prairie country, and can dimly descry, in the far distance, the thin, dark line which another hour's ride will show to be the narrow fringe of timber that marks the course of the famous Red River of the North, that true Arimaspes, with whose golden sands thousands and tens of thousands have been made rich. This, then, is the renowned Red River valley, the story of whose amazing fertility has attracted, from older States and still older countries, one hundred and fifty thousand people. The greatest influx has taken place since 1880, the increase in population between the census of that year and that in the spring of 1885 being 38,719 on the Minnesota side of the river, and 54,918 on the Dakota side. Although there are vast tracts of land still uncultivated, the general appearance of the valley is that of a well-settled agricultural country. But this will occasion no surprise to those who remember that its annual wheat crop has now reached 25,000,000 bushels, and its crop of other cereals 15,000,000 bushels. Not a little surprise, however, is occasioned by the discovery that the "valley" of which the traveler has heard so much is not a valley at all, but a great plain, whose slope toward the river is so slight as to be wholly imperceptible. Where the railroad crosses the river, have sprung up the cities of Moorhead and Fargo, the former in Minnesota, the latter in Dakota. With such advantages of situation as they possess, and with the days of booms, with all their unhealthy excitement and fictitious values, gone, never, it is to be hoped, to return, these cities must continue to increase in commercial importance, with the development of the rich country surrounding them. Fargo is, indeed, the largest city in the entire Territory of Dakota, and will probably retain its position as such for many years to come.
