The morning being fair I sent out all the hunters, and directed two of them to procede down the river as far as it's junction with the Eastern fork which heads near the missouri, and return this evening. this fork of the river we determined to name the Valley plain river. I think it most probable that this river continues it's course along the rocky Mts. Northwardly as far or perhaps beyond the scources of Medecine river and then turning to the West falls into the Tacootchetessee. The Minetares informed us that there was a large river west of, and at no great distance from the sources of Medecine river, which passed along the Rocky Mountains from S. to N.this evening one of our hunters returned accompanyed by three men of the Flathead nation whom he had met in his excurtion up travellers rest Creek. on first meeting him the Indians were allarmed and prepared for battle with their bows and arrows, but he soon relieved their fears by laying down his gun and advancing towards them. the Indians were mounted on very fine horses of which the Flatheads have a great abundance; that is, each man in the nation possesses from 20 to a hundred head. our guide could not speake the language of these people but soon engaged them in conversation by signs or jesticulation, the common language of all the Aborigines of North America, it is one understood by all of them and appears to be sufficiently copious to convey with a degree of certainty the outlines of what they wish to communicate. in this manner we learnt from these people that two men which they supposed to be of the Snake nation had stolen 23 horses from them and that they were in pursuit of the theaves. they told us they were in great hast, we gave them some boiled venison, of which the eat sparingly. the sun was now set, two of them departed after receiving a few small articles which we gave them, and the third remained, having agreed to continue with us as a guide, and to introduce us to his relations whom he informed us were numerous and resided in the plain below the mountains on the columbia river, from whence he said the water was good and capable of being navigated to the sea; that some of his relation were at the sea last fall and saw an old whiteman who resided there by himself and who had given them some handkerchiefs such as he saw in our possession.— he said it would require five sleeps wich is six days travel, to reach his relations. the Flatheads are a very light coloured people of large stature and comely form.
