from 150 to 300 miles. Its banks, near its outlet, are subject to inundation to a considerable extent. Grand River, which enters the Missouri about 250 miles from its mouth, runs nearly parallel with, and not far distant from it, across an immense tract of country, and is said to be navigable 600 miles. Near its mouth, which is ninety yards in width, sand bars were discovered, and the banks on the north side were seen to fall in. Below its junction, the navigation of the Missouri, owing to the same circumstance, is also difficult. Formerly, when the traders of the Missouri were prevented by the Kansas Indians from ascending this river to the country of the Mahas, 800 miles distant, they continued their commerce by the channel of the Grand River. White River issues from several small lakes, of which the most westerly is in the 105th meridian of longitude, and runs in an eastern direction to its confluence with the Missouri, below the Grand Detour, or Great Bend, of this river. At its junction, it is 300 yards in width, and it is navigable to the distance of 600 miles. Qui Court River rises in the Black Mountains, near the sources of Tongue River, and follows a course south-east by east, nearly parallel with the Platte, through a hilly country. Its confluence, which is about 1000 miles from the Mis *On Melish's Map called Quicoarre. sissippi, is 150 yards in breadth, but its current is too rapid for navigation. The Little Missouri River rises to the west of the Black Mountains, and passes near the north-west side of the Turtle Hills in its course to the Missouri, with which it unites on the south-west side, 1690 miles from the confluence of this river with the Mississippi. It is 134 yards in width near its mouth, and though in many parts there are from six to seven feet water, it is not navigable. Great Sioux River rises in an elevated and well wooded country, called " Moun“tain of the Prairie," near the head waters of the St Peter's River of the Mississippi, and runs in a southern direction, till it arrives near, and almost opposite to, the Grand Detour of the Missouri, where it takes an easterly direction; after which, it receives three streams from the north-east-the Prickly Pear River, the River of the Rock, and the Red Pipe Stone River; and taking a southeasterly course, joins the Missouri, where its waters are 110 yards in breadth. According to the report of Indian traders, and of Durion, interpreter to Lewis and Clarke, it is navigable more than 200 miles, to certain rocks or falls. James or Yankton River rises in an elevated country, above the head waters of the St Peter's of the Mississippi, nearly in the same latitude * with the * On Melish's Map below the 47th degree of latitude. old Mandan villages, and runs a southerly course, nearly parallel with the Missouri, which it enters almost at right angles, the latter assuming an eastern direction above the place of junction. The Yankton is ninety yards in width at its confluence with the Missouri, and is navigable to the distance of 300 miles. Having thus described the great tributary streams of the Missouri, we come now to those which are less considerable; some of which, however, in point of magnitude, are equal to the most celebrated rivers of Europe. Bonhomme, or Goodman's River, is a considerable stream, which enters on the southern side. Osage Woman River enters on the northern side, and is thirty yards wide at its junction. On its banks there is a settlement of thirty or forty farmers, emigrants from different parts of the United States; and, a little beyond this place, there is a creek, called Charette, which, in 1804, marked the limits of the American white settlements on the Missouri. Gasconade River traverses a hilly country, of 150 miles extent, and runs into the Missouri on the south-west side, 100 miles from the Mississippi. Its mouth is 157 yards in breadth, the depth of the channel nineteen feet, and it is navigable to the distance of * * According to Pike it is 200 yards. 100 miles. Big Muddy River and Bear Creek, which enter near the Osage River, are considerable streams; the former being fifty, the latter twenty-five yards in width. Their banks are fertile and well wooded. Saline or Salt River, so called on account of its brackish waters, is a rapid stream, with an outlet of thirty yards in width. Good Woman's River, which enters on the northeast side, 191 miles from the Mississippi, is thirtyfive yards wide at its mouth, and is navigable thence to the distance of several leagues. Mine River enters on the south-west side, at the distance of nine miles from the former, traverses a rich country, and is boatable eighty or ninety miles from its mouth, which is seventy yards in breadth. At the distance of five or six leagues from the Missouri, it divides itself into two branches; and between these are rich salt springs, which render the waters of the western branch unfit for domestic use. Charaton Rivers. The two rivers which bear this name enter the Missouri on the north-east side, near each other, at the distance of 220 miles from the Mississippi, and are navigable for boats, the one to the distance of fifty, the other of 100 miles. The largest is thirty, the other seventy, yards wide at the point of junction; and they pass through a rich, broken, and well wooded country, from their source near some of the branches of the River de Moins. The Little Shallow River, or Petite Rivière Platte, which enters on the north-east side, 349 miles from the Mississippi, is sixty yards wide near its mouth, and is navigable to the distance of forty miles. The surface extending between this country and the Missouri is sometimes overflowed by their waters, which never takes place towards the south. Blue Water River enters on the south-western side, 331 miles from the Mississippi. Its mouth is thirty yards in width. Nodawah River enters on the north-east side, where its channel is contracted by the mud of the Missouri, above which the width is seventy yards, and it is said to be navigable to the distance of as many miles. Wolf River is sixty yards wide at its entrance on the southwest side, 464 miles from the Mississippi, and is navigable for boats towards its source, which is near that of the Kansas. The Great Nemahah enters on the south-west side, under the parallel of 39° 55′ north latitude, 480 miles from the Mississippi. It is eighty yards in width at its confluence; and its banks, to a considerable distance, consist of freestone. Neshnabatonah River runs a considerable distance nearly parallel with the Missouri, through a country abounding with forest-wood, oak, walnut, and mulberry, and joins this river on the north-east side, 508 miles from the Mississippi. At its confluence it is fifty yards in width. Little Nemahah River has its junction on the south-west |
