In one of these tenements, consisting of a small cabin of poles, sheathed with bark, we found an object of human misery which excited our sympathies. It was in the person of one of the Canadians, to whom reference has been made, of the name of Montruille. He had, in the often severe peregrinations of the fur trade in this quarter, been caught in a snow-storm during the last winter, and frozen both his feet in so severe a manner that they eventually sloughed off, and he could no longer stand upright or walk. He lay on the ground in a most pitiable state of dejection, with the stumps of his legs bound up with deer skins, with a gray, long-neglected beard, and an aspect of extreme despair. English he could not speak; and the French he uttered was but an abuse of the noble gift of language to call down denunciations on those who had deserted him, or left him thus to his fate. A rush mat lay under him. He had no covering. He was emaciated to the last degree, every bone in his body seemed visible through the skin. His cheeks were fallen in, and his eyes sunk in their sockets, but darting a look of despair. His Indian wife had deserted him. Food, of an inadequate quality, was occasionally thrown in to him. Such were the accounts we received. Governor Cass directed groceries, ammunition, and presents of clothing to be made to him, to the latter of which, every member of the party added. He also engaged a person to convey him to Sandy Lake.

We examined the environs of the place with interest; the village occupies the north banks of Turtle River Valley. Turtle River, which cuts its way through this slope and plain, constitutes the direct line of intercourse for the Indian trade, through Turtle and Red Lakes, to the Red River Valley of Hudson's Bay. On inquiry, we learned that this river had constituted the ancient Indian line of communication by canoes and portages, from time immemorial, with that valley, the distance to the extreme plateau, or summit, being about sixty miles. On this summit, within a couple of miles of each other, lie Turtle and Red Lakes, the one having its discharge into the Gulf of Mexico and the other into Hudson's Bay. When Canada was settled by the French, this aboriginal route was adopted. The fur companies of Great Britain, on coming into possession of the country, after the fall of Quebec, 1759, followed the same route. The factors of these companies told Lieutenant Pike, in 1806, at Sandy Lake and Leech Lake, that the Turtle portage was the only practicable route of communication to the Red River, and that it was the true source of the Mississippi; and they furnished him manuscript maps of the country conformable to these views. The region has actually been in possession of the Americans only since 1806, adopting the era of Pike's visit.

By inquiry from the Chippewa Indians at this village, sanctioned by the Canadian authorities, we are informed that the Mississippi falls into the south end of Cass Lake, at the distance of eight or ten miles; that it reaches that point from the west, by a series of sharp rapids stretching over an extent of about forty miles from a large lake; [73] and that this celebrated stream originates in Lac la Biche, about six days' journey from our present position, and has many small lakes, rapids, and falls. It is further asserted by the Indians, that the water in these remote streams, and upon these rapids, is at all times shallow, but it is particularly so this season; and that it is not practicable to reach these remote sources of the river with boats, or large canoes of the size we have.

On submitting these facts to the gentlemen composing his party, Governor Cass asked each one to give his views, beginning with the youngest, and to express his opinion on the feasibility of further explorations. They concurred in opinion that, in the present low state of the water on these summits, considering the impossibility of ascending them with our present craft, and in the actual state of our provisions, such an attempt was impracticable. Thereon, he announced his decision to rejoin our party at Sandy Lake, and to pursue the exploration of the river down its channel to the Falls of St. Anthony, to the inlet of the Wisconsin and Fox Rivers, and to return into the great lake basins, and complete their circumnavigation.

Having reached the ultimate geographical point visited by the expedition, I thought it due to the energy and enlightened zeal of the gentleman who had led us, to mark the event by naming this body of water in my journal Cassina, or Cass Lake. There was the more reason for this in the nomenclature of the geography of the upper Mississippi, by observing that it embraces another Red Cedar Lake. The latitude of upper Red Cedar, or Cass Lake, is placed by Pike at 47° 42´40´´. [74] Its distance above Sandy Lake, by the involutions of the river, is two hundred and seventy miles, and from Fond du Lac, at the head of Lake Superior, by the travelled route, four hundred and thirty miles. It is situated seventeen degrees north of the Gulf of Mexico, from which it is computed to be distant two thousand nine hundred and seventy-eight geographical miles. Estimating the distance to the actual origin of the river, as determined at a subsequent period, at one hundred and eighty-two miles above Cass Lake, the length of the Mississippi River is shown to be three thousand one hundred and sixty miles, [75] making a direct line over the earth's surface of more than half the distance from the arctic circle to the equator. It may also be observed of the Mississippi, that its sources lie in a region of snows and long-continued winter, while it enters the ocean under the latitude of perpetual verdure; and at last, as if disdaining to terminate its career at the ordinary point of embouchure of other large rivers, has protruded its banks into the Gulf of Mexico, more than a hundred miles beyond any other part of the main. To have visited both the source and the mouth of the stream has fallen to the lot of but few, and I believe there is no person living beside myself of whom the remark can be made. On the tenth of July, 1819, I passed out of the mouth of the Mississippi in a brig bound for New York, after descending it in a steamboat from St. Louis, but little thinking I should soon visit its waters, yet, on the twenty-first of July of the following year, I reached its sources in this lake.

In deciding upon the physical character of the Mississippi River, it may be advantageously considered under four natural divisions, as indicated by permanent differences in its geological and physical character—its vegetable productions, and its velocity and general hydrographical character. Originating in a region of lakes upon the table-lands which throw their waters north into Hudson's Bay, south into the Gulf of Mexico, and east into the Gulf of St. Lawrence, it pursues its course south to the Falls of Pakagama, a distance of two hundred and thirty miles, through natural meadows or savannas covered with wild rice, rushes, reeds and coarse grasses, and aquatic plants. During the distance, it is extremely devious in its course and width, often expanding into lakes which connect themselves through a vast system of reticulated channels. Leech Lake, Cass Lake, and Lake Andrúsia would themselves be regarded as small interior seas, were they on any other part of the continent but that which develops Superior, Michigan, Huron, Erie, and Ontario. Its velocity through the upper plateau is but little, and it affords every facility for the breeding of water fowl and the small furred quadrupeds, the favorite reliance of a nomadic population.

At the Falls of Pakagama, the first rock stratum and the first wooded island is seen. Here the river has an aggregate fall of twenty feet, and from this point to St. Anthony's Falls, a distance of six hundred miles, it exhibits its second characteristic division. The granitical and metamorphic rocks, which support the vast plateaux and beds of draft of its sources, are only apparent above this point, in boulders. The permanent strata are but barely concealed at several rapids below the Pakagama, but appear plainly below the influx of the De Corbeau, at Elk River, Little Falls, and near Sac River. And this system of rock is succeeded, before reaching the Falls of St. Anthony, by the horizonal white sand rock and its superior limestone series of the carboniferous formation.

Vegetation is developed as the river descends towards the south. A forest of maples, elm, oak, ash, and birch, is interspersed with spruce, birch, poplar, and pine above the Pakagama, and continues, in favorable positions, throughout this division. The black walnut is first seen below Sandy Lake, and the sycamore below the River De Corbeau. The river in this division has numerous well-wooded islands; its velocity is a striking feature; it abounds with rapids, none of which, however, oppose serious obstacles to its navigation. Agreeably to memoranda kept, [76] it has fifty-six distinct rapids, including the Little and Big Falls, in all of which the river has an aggregate estimated descent of two hundred and twenty-four feet, within a distance of fourteen thousand six hundred and forty yards, or about eight miles. The mean fall of the current, exclusive of these rapids, may be computed at nearly six inches per mile.

The course of the river, below the Falls of Pakagama, is still serpentine, but strikingly less so than above, and its bends are not so short and abrupt. The general course of this river, till it reaches the rock formation of Pakagama, is from the west. Thence, to Sandy Lake inlet, it flows generally southeast; from this point to the inlet of the De Corbeau or Crow Wing, it is deflected to the southwest; thence almost due south, to the mouth of the Watab River; and thence again southeast to the Falls of St. Anthony. A geographical line dropped from the inlet of Sandy Lake, where the channel is first deflected to the southwest, to St. Anthony's Falls, or the mouth of the St. Peter's, [77] forms a vast bow-shaped area of prairie and forest lands of high agricultural capabilities, whose future products must be carried to a market through the Fond du Lac of Lake Superior. These prairies and grove lands, which cannot square less than two by four hundred miles, constitute the ancient area of the Issati, [78] and are now the resort of great herds of the buffalo, elk, and deer; and it is a region known as the predatory border, or battle-ground of the Chippewas and Dacotas.
