From the Fall of St. Anthony, my delightful companion (Mr. Wood, whom I have before mentioned) and myself, with our Indian guide, whose name was O-kup-pee, tracing the beautiful shores of the St. Peters river, about eighty miles; crossing it at a place called “_Traverse des Sioux_,” and recrossing it at another point about thirty miles above the mouth of “_Terre Bleue_,” from whence we steered in a direction a little North of West for the “Côteau des Prairies,” leaving the St. Peters river, and crossing one of the most beautiful prairie countries in the world, for the distance of one hundred and twenty or thirty miles, which brought us to the base of the Côteau, where we were joined by our kind and esteemed companion Monsieur La Fromboise, as I have before related. This tract of country as well as that along the St. Peters river, is mostly covered with the richest soil, and furnishes an abundance of good water, which flows from a thousand living springs. For many miles we had the Côteau in view in the distance before us, which looked like a blue cloud settling down in the horizon; and we were scarcely sensible of the fact, when we had arrived at its base, from the graceful and almost imperceptible swells with which it commences its elevation above the country around it. Over these swells or terraces, gently rising one above the other, we travelled for the distance of forty or fifty miles, when we at length reached the summit; and from the base of this mound, to its top, a distance of forty or fifty miles, there was not a tree or bush to be seen in any direction, and the ground everywhere was covered with a green turf of grass, about five or six inches high; and we were assured by our Indian guide, that it descended to the West, towards the Missouri, with a similar inclination, and for an equal distance, divested of every thing save the grass that grows, and the animals that walk upon it.
