Physical Features. The physical features of this Valley are peculiar.
1. It includes two great inclined planes, one on its eastern, and the other on its western border, terminating with the Mississippi.
2. This river receives all the waters produced on these slopes, which are discharged by its mouths into the gulf of Mexico.
3. Every part of this vast region can be penetrated by steamboats, or other water craft; nor is there a spot in all this wide region, excepting a small district in the vast plains of Upper Missouri, that is more than one hundred miles from some navigable water. A boat may take in its lading on the banks of the Chatauque lake, in the State of New York; another may receive its cargo in the interior of Virginia; a third may start from the rice lakes at the head of the Mississippi; and a fourth may come laden with furs from the Chippewan mountains, 2,800 miles up the Missouri, and all meet at the mouth of the Ohio, and proceed in company to the ocean.
4. With the exception of its eastern and western borders, there are no mountains. Some portions are level, a large part is gently undulating, or what in the west is called "rolling," and the remainder is made up of abrupt hills, flint and limestone ridges, bluffs, and ravines.
5. It is divided into two great portions, the Upper, and Lower Valley, according to its general features, climate, staple productions, and habits of its population. The parallel of latitude that cuts the mouth of the Ohio river, will designate these portions with sufficient accuracy.
North of this line the seasons are regularly divided into spring, summer, autumn, and winter. In the winter there is usually more or less snow, ice forms and frequently blocks up the rivers, navigation is obstructed, and cotton is not produced in sufficient quantity or quality to make it a staple for exportation. It is the region of furs, minerals, tobacco, hemp, live stock, and every description of grain and fruit that grows in New England. Its white population are mostly accustomed to labor.
South of this line, cotton, tobacco, indigo, and sugar are staples. It has little winter, snow seldom covers the earth, ice never obstructs the rivers, and most of the labor is done by slaves.
Rivers. The rivers are, the Mississippi and its tributaries, or more correctly, the Missouri and its tributaries. If we except the Amazon, no river can compare with this for length of its course, the number and extent of its tributaries, the vast country they drain, and their capabilities for navigation. Its tributaries generally issue either from the eastern or western mountains, and flow over this immense region, diffusing not only fertility to the soil, but affording facilities for commerce a great part of the year.
The Missouri is unquestionably the main stream, for it is not only longer and discharges a larger volume of water than the Mississippi above its mouth, but it has branches, which, for the extent of country they drain, their length, and the volume of water they discharge, far exceed the upper Mississippi.
The characteristics of these two rivers are each distinctly marked. The Missouri is turbid, violent in its motions, changing its currents; its navigation is interrupted or made difficult by snags, sawyers and planters, and it has many islands and sand-bars. Such is the character of the Mississippi below the mouth of the Missouri. But above its mouth, its waters are clear, its current gentle, while it is comparatively free from snags and sand-bars.
The Missouri, which we have shown to be the principal stream, rises in the Chippewan, or Rocky mountains in latitude 44° north, and longitude about 35° west from Washington city. It runs a northeast course till after it receives the Yellow Stone, when it reaches past the 48° of latitude, thence an east, then a south, and finally a southeastern course, until it meets the current of the Mississippi, 20 miles above St. Louis, and in latitude 38° 45' north. Besides numerous smaller streams, the Missouri receives the Yellow Stone and Platte, which of themselves, in any other part of the world, would be called large rivers, together with the Sioux, Kansau, Grand, Chariton, Osage, and Gasconade, all large and navigable rivers.
Its length, upon an entire comparative course, is 1870 miles, and upon a particular course, about 3000 miles. Lewis and Clark make the distance from the Mississippi to the great falls, 2580 miles.
There are several things in some respects peculiar to this river, which deserve notice.
1. Its current is very rapid, usually at the rate of four or five miles an hour, when at its height; and it requires a strong wind to propel a boat with a sail against it. Steam overcomes its force, for boats ply regularly from St. Louis to the towns and landings on its banks within the borders of the state, and return with the produce of the country. Small steamboats have gone to the Yellow Stone for furs.
Owing to the shifting of its current, and its snags and sand-bars, its navigation is less safe and pleasant than any other western river, but these difficulties are every year lessened by genius and enterprise.
2. Its water is always turbid, being of a muddy, ash color, though more so at its periodical rise than at other times. This is caused by extremely fine sand, received from the neighborhood of the Yellow Stone. During the summer flood, a tumbler of water taken from the Missouri, and precipitated, will produce about one fourth of its bulk in sediment.
This sediment does not prevent its habitual use by hundreds who live on its banks, or move in boats over its surface. Some filtrate it, but many more drink it, and use it for culinary purposes, in its natural state.
When entirely filtrated, it is the most limpid and agreeable river water I ever saw. Its specific gravity then, is about equal to rain water; but in its turbid state, it is much heavier than ordinary river water, for a boat will draw three or four inches less in it than in other rivers, with the same lading, and the human body will swim in it with but very little effort.
It possesses some medicinal properties. Placed in an open vessel and exposed to the summer's sun, it remains pure for weeks. Eruptions on the skin and ulcerous sores are cured by wading or frequent bathings, and commonly it produces slight cathartic effects upon strangers upon its first use.
The width of the Missouri river at St. Charles, is 550 yards. Its alluvial banks however are insecure, and are not unfrequently washed away for many yards at its annual floods. The bed of its channel is also precarious, and is elevated or depressed by the deposition or removal of its sandy foundation. Hence the elevation or depression of the surface of this river, affords no criterion of its depth, or of the volume of water it discharges at any one period.
Undulatory motions, like the boiling of a pot, are frequently seen on its surface, caused by the shifting of the sand that forms its bed.
The volume of water it ordinarily discharges into the Mississippi is vastly disproportionate to its length, or the number and size of its tributaries. I have seen less than six feet depth of water at St. Charles at a low stage, and it was once forded by a soldier, at Bellefontaine, four miles above its junction with the Mississippi.
Evaporation takes up large quantities, but absorption throughout the porous soil of its wide bottoms consumes much more. In all the wells dug in the bottom lands of the Missouri, water is always found at the depth of the surface of the river, and invariably rises or sinks with the floods and ebbings of the stream. Volumes of sand frequently enter these wells as the river rises.
Its periodical floods deserve notice. Ordinarily this river has three periods of rising and falling each year. The first rise is caused by the breaking up of winter on the Gasconade, Osage, Kansau, Chariton, Grand, and other branches of the lower Missouri, and occurs the latter part of February, or early in March. Its second rise is usually in April, when the Platte, Yellow Stone, and other streams pour into it their spring floods. But the flood that more usually attracts attention takes place from the 10th to the 25th of June, when the melting snows on the Chippewan mountains pour their contents into the Missouri. This flood is scarcely ever less than five, nor more than 20 feet at St. Louis,
