the Naiwa, which came in on the left, was a stream of considerable length, and originated in a lake which was infested by copper-head snakes, to which its name has reference. I observed that the soil at this place was of a diluvian character, and embraced pebbles, and small boulders of syenite, trap rock, and quartz, and other debris of primitive and secondary rocks. One of the party picked up a well characterised piece of zoned agate.
While the mending of the canoes was in progress, the baggage was put in portable order, and as soon as all was ready, the men moved on with the canoes and effects, which were so arranged that all could be carried at one load, and it did not require them to go back. This was a point originally kept in view, in the curtailment of the baggage at the island, and it was an object of the highest importance to the speed and success of the trip. Each canoe and its apparatus, with some of the lighter pieces was carried by one man. The guide led off the men, with no slight burden on his own shoulders, first scrambling up the sandy acclivity, and then striking through a growth of scrub oak and pines. The showers of the morning had so thoroughly wet the grass and shrubbery, that a few moments walking through it, was sufficient completely to saturate both pantaloons and stockings. I walked out a few hundred yards from the trail, towards the left which brought me into the curve of the river, in view of the rapids. There appeared to be a series of small rapids, with intervening shallows. The noise of falling water and the white wreaths of foam, induced me to think there might be distinct falls, but I could discern nothing entitled to the name. The average descent of the river, at this series of rapids, appeared to be, however, considerable, and might perhaps be estimated at forty-eight feet. I rejoined the party at the spot they had selected for their first pause, somewhat to their relief, probably, as guns had been fired by them, under the belief of my having missed the way. We first came in sight of the river again, on the brow of an elevated sand-hill, precipitous towards the water. The guide halted to inquire whether it would not be preferable to encamp at this spot, as we should suffer less from insects than if we encamped in the valley of the river, at the termination of the portage. As the day light was not gone, and some distance still remained, I deemed it better to go on, that we might have nothing to do in the morning, but to put our canoes in the water. On reaching the bank of the stream, we found its current placid, and our guide informed us that we had now surmounted the last rapids.
A fog prevented our embarking until five o’clock in the morning, (13th) and it was then impossible to discern objects at a distance. We found the channel above the Naiwa, diminished to a clever brook, more decidedly marshy in the character of its shores, but not presenting in its plants or trees, any thing particularly to distinguish it from the contiguous lower parts of the stream. The water is still and pond-like. It presents some small areas of wild rice. It appears to be a favorite resort for the duck and teal, who frequently rose up before us, and were aroused again and again by our progress. An hour and a half diligently employed, brought us to the foot of Ossowa Lake. We halted a moment to survey it. It exhibits a broad border of aquatic plants, with somewhat blackish waters. Perch abound in it. It is the recipient of two brooks, and may be regarded as the source of this fork of the Mississippi. We were precisely twenty minutes in passing through it. We entered one of the brooks, the most southerly in position. It possessed no current and was filled with broad leaved plants, and a kind of yellow pond-lily. We appeared to be involved in a morass, where it seemed equally impracticable to make the land, or proceed far by water. In this we were not mistaken; Oza Windib soon pushed his canoe into the weeds and exclaimed, Oma, mikunna, (here is the portage.) A man who is called on for the first time, to debark, in such a place, will look about him to discover some dry spot to put his feet upon. No such spot however existed here. We stepped into rather warm pond water, with a miry bottom. After wading a hundred yards, or more, the soil became firm, and we soon began to ascend a slight elevation, where the growth partakes more of the character of a forest. Traces of a path appeared here, and we suddenly entered an opening affording an eligible spot for landing. Here our baggage was prepared for the portage. The carbonaceous remains of former fires, the bones of birds, and scattered camp poles, proved it to be a spot which had previously been occupied by the Indians. The prevailing growth at this place, is spruce, white cedar, tamarack and grey pine. We here breakfasted.
Having followed out this branch of the Mississippi to its source, it may be observed, that its existence, as a separate river, has hitherto been unknown in our geography. None of the maps indicate the ultimate separation of the Mississippi, above Cass Lake, into two forks. Little surprise should therefore be manifested that the latitude of the head of this stream, is found to be incorrect. It was not however to be expected that the inaccuracy should be so great as to place the actual source, an entire degree south of the supposed point. Such however is the conclusion established by present observations.
The portage from the east to the west branch of the river, is estimated to be six miles. Beginning in a marsh, it soon rises into a little elevation of white cedar wood, then plunges into the intricacies of a swamp matted with fallen trees, obscured with moss. From this, the path emerges upon dry ground. It soon ascends an elevation of oceanic sand, having boulders, and bearing pines. There is then another descent, and another elevation. In short, the traveller now finds himself crossing a series of deluvial sand ridges, which form the height of land between the Mississippi Valley and Red River. This ridge, is locally denominated Hauteur des Terres where it is crossed in passing from Lac Plaie to Ottertail Lake, from which point it proceeds northward, separating the tributaries of the River des Corbeau from those of Red River. It finally subtends both branches of the Mississippi, putting out a spur between the east and west fork, which intersects the portage, crosses the west or Itascan fork about the point of the Kakábikonce, or Little Rock Falls, and joining the main ridge, passes northeastwardly of Lac Travers and Turtle Lake, and is again encountered in the noted portage path from Turtle Lake to Red Lake. It is, in fine, the table land between the waters of Hudson’s Bay and the Mexican Gulf. It also gives rise to the remotest tributaries of the river St. Louis, which, through Lake Superior and its connecting chain, may be considered as furnishing the head waters of the St. Lawrence. This table land, is probably, the highest in North-western America, in this longitude.
In crossing this highland, our Indian guide, Oza Windib, led the way, carrying one of the canoes, as his portion of the burden. The others followed, some bearing canoes, and others baggage. The whole party were arranged in Indian file, and marched rapidly a distance—then put down their burthens a few moments, and again pressed forward. Each of these stops is called a posè by the voyageurs, and is denominated Opugid-jiwunon, or a place of putting down the burthen, by the Indians. Thirteen of these rests, are deemed the length of the portage. The path is rather blind, and requires the precision of an Indian eye to detect it. Even the guide was sometimes at a loss, and went forward to explore. We passed a small lake occupying a vale, about midway of the portage, in canoes. The route beyond it, was more obstructed with underbrush. To avoid this, we waded through the margins of a couple of ponds, near which we observed old camp poles, indicating former journies by the Indians.
The weather was warm and not favorable to much activity in bird or beast. We saw one or two species of the falco, and the common pigeon, which extends its migrations over the continent. Tracks of deer were numerous, but travelling without the precaution required in hunting, we had no opportunity of seeing this animal on the high grounds. It was observed in the valleys of the river, on both branches. Ripe straw berries were brought to me, by the men, at one of the resting places. I observed a very diminutive species of the raspberry, with fruit, on the moist grounds. Botanists would probably deem the plants few, and destitute of much interest. Parasitic moss is very common to the forest trees, and it communicates a peculiar aspect to the grey pine, which is the prevailing growth on all the elevations.
To the geologist, the scene is one of interest. The boulders of granite, and other primitive strata, occurring on the surface, remind him of the original position of these masses, in the system of nature and indicate revolutions affecting the earth’s surface, which have widely changed both the position and form of these solid materials. When the soil itself is examined, it adds further evidences of such changes. We may refer its sand to consolidated strata of this mineral which have been broken down by oceanic action, and distributed in the remarkable ridges and elevations, which now characterise the face of the country. In whatever light the subject is viewed, it seems difficult to resist the conclusion, that water has been the cause, under providence,
