SIR: I had the honor to inform you some time since that I had reached this place by land from Chicago, and that the residue of the party were daily expected. They arrived soon after, without accident, and this long and arduous journey has been accomplished without the occurrence of any unfavorable incident. I shall submit to you, as soon as it can be prepared, a memoir respecting the Indians who occupy the country through which we passed; their numbers, disposition, wants, &c. It will be enough at present to say, that the whole frontier is in a state of profound peace, and that the remote Indians, more particularly, exhibit the most friendly feelings towards the United States. As we approach the points of contact between them and the British, the strength of this attachment evidently decreases, and about those points few traces of it remain. During our whole progress but two incidents occurred which evinced in the slightest degree, an unfriendly spirit. One of these was at St. Mary's, within forty-five miles of Drummond's Island, and the other within thirty miles of Malden. They passed off, however, without producing any serious result. It is due to Colonel Leavenworth to say, that his measures upon the subject of the outrage committed by the Winnebago Indians, in the spring, were prompt, wise, and decisive. As you have long since learned, the murderers were soon surrendered; and so impressive has been the lesson upon the minds of the Indians, that the transaction has left us nothing to regret, but the untimely fall of the soldiers. In my passage through the Winnebago country, I saw their principal chiefs, and stated to them the necessity of restraining their young men from the commission of acts similar in their character to those respecting which a report was made by Colonel Smith. I have reason to believe that similar complaints will not again be made, and I am certain that nothing but the intemperate passions of individuals will lead to the same conduct. Should it occur, the act will be disavowed by the chiefs, and the offenders surrendered with as much promptitude as the relapsed state of the government will permit. The general route which we pursued was from this place to Michilimackinac by the southern shore of Lake Huron. From thence to Drummond's Island and by the River St. Mary's to the Sault. We there entered Lake Superior, coasted its southern shore to Point Kewena, ascended the small stream, which forms the water communication across the base of the point, and, after a portage of a mile and a half, struck the lake on the opposite side. Fifty miles from this place is the mouth of the Ontonagan, upon which have been found large specimens of copper.
