I observed, as the crews of the several canoes threw down their day's game before the cook, there was a species of duck, the anas canadensis, I think, which had a small unio attached to one of its mandibles, having been engaged in opening the shell at the moment it was shot. With every aid, however, from the tent and the tea-kettle, and our cook's art in spitting ducks, the night here, in a gloomy and damp thicket, just elevated above the line of the river flags, and quite in the range of the frogs and lizards, proved to be one of the most dreary and forlorn. It was felt that we were no longer on the open Mississippi, but were winding up a close and very serpentine tributary, nowhere over thirty feet wide, which unfolded itself in a savanna, or bog, bordered closely with lagoons and rice ponds. Indian sagacity, it was clear, had led Ozawindib up this tributary as the best, shortest, and easiest possible way of reaching to, and surmounting the Itasca plateau, but it required a perpetual use of hand, foot, paddle, and pole; nor was there a gleam of satisfaction to be found in anything but the most intense onward exertion. Besides, I had agreed to meet the Indians at the mouth of the Crow-Wing River on the 24th of July, and that engagement must be fulfilled. At five o'clock the next morning (12th) we were on our feet, and resumed the ascent. The day was rainy and disagreeable. There was little strength of current, but quite a sufficient depth of water; the stream was excessively tortuous. Owing to the sudden bends, we often frightened up the same flocks of brant, ducks, and teals again and again, who did not appear to have been in times past much subjected to these intrusions. The flora of this valley appeared unfavorable. Dr. Houghton has reported a new species of malva and some five or six other species or varieties from the general region, but these have not, I think, been elaborately described. The localities of the known species of fauna might be marked by the occurrence, on this fork, of the cervus virginianus, which had not been seen after leaving the Sandy Lake summit till after getting above the primary forks, which flow from the south and west.
