"I arrived at this place (Ft. Hall) on the 13th inst., with my part of the caravan all safe and in tolerable order. * * * (Unimportant part skipped). Lt. Fremont, whom I parted with on the South fork of the Platte, and expected to meet at this place, joined us yesterday after making a survey of the Salt Lake, which he has done much to his satisfaction. The exploration and new routes which we have taken have made our trip tedious and very laborious, but, I hope it will be satisfactory to the Department. We leave tomorrow for the lower country, and find it necessary to let some of our men off on account of the scarcity of provisions, which are not to be had at this place. The full objects of the expedition, will, I hope, be completed ere we return. I shall leave the party in a few days for Walla Walla, or perhaps lower down, to provide necessary supplies for the completion of the business in that quarter. I can not say what time we will return to St. Louis; it is to be hoped before the adjournment of Congress. The emigrants passed this place some short time since, pretty well worn down and scarce of food. The Indians on the Columbia are expected to become troublesome to these newcomers. It is supposed they are induced to acts of violence by some persons as yet unknown. They have already burned Dr. Whitman's mill, and I fear it is not the last spark which will be kindled in the settlement and occupation of this country. The Hudson's Bay Company are improving and pushing their business, perhaps with greater energy than usual, Dr. McLoughlin is laying off towns on the Willamette, selling lots, etc. This is the report, and you can see that the Dr. is in advance of Dr. Linn's bill." The foregoing is the latest news from Oregon, and may be relied upon as correct. Not the least interesting part of it is that which relates to the disposition of the Indians towards the emigrants. We have always believed that the Indians, backed and incited as they will be by agents and emissaries of the Hudson's Bay Co., and furnished as they doubtless will be, with arms and means of warfare from some source, would oppose the emigrants in making their settlements. That the country must be conquered before it is attained, we hardly entertain a doubt, and if we did, the supineness of our Government would only strengthen the belief. Why is it that our Government is so indifferent to the claims of the nation upon this territory, its wealth and possessions? * * * * * St. Louis _Reveille_, Oct. 21, 1844. The Platte _Argus_ contains a letter from "Multnomah City," Oregon, from which we make the following extracts. The killing of the Indian has been briefly mentioned heretofore.
