The Assiniboins have so recently left the river that game is scarce and shy. One of the hunters shot at an otter last evening; a buffaloe too was killed, and an elk, both so poor as to be almost unfit for use; two white bear were also seen, and a muskrat swimming across the river. The river continues wide and of about the same rapidity as the ordinary current of the Ohio. The low grounds are wide, the moister parts containing timber, the upland extremely broken, without wood, and in some places seem as if they had slipped down in masses of several acres in surface. The mineral appearances of salts, coal, and sulphur, with the burnt hill and pumicestone continue, and a bituminous water about the colour of strong lye, with the taste of glauber salts and a slight tincture of allum. Many geese were feeding in the prairies, and a number of magpies who build their nest much like those of the blackbird in trees, and composed of small sticks, leaves and grass, open at top: the egg is of a bluish brown color, freckled with reddish brown spots. We also killed a large hooting owl resembling that of the United States, except that it was more booted and clad with feathers. On the hills are many aromatic herbs, resembling in taste, smell and appearance the sage, hysop, wormwood, southern wood, juniper and dwarf cedar; a plant also about two or three feet high, similar to the camphor in smell and taste, and another plant of the same size, with a long, narrow, smooth, soft leaf, of an agreeable smell and flavour, which is a favourite food of the antelope, whose necks are often perfumed by rubbing against it.
