James's Account of S. H. Long's Expedition, 1819-1820, part 4

by Edwin James; Stephen H. Long; Thomas Say

The most considerable rivers intersecting this section of country are the Muskingum, Sciota, Big Miami, and Wabash, all of which, in the spring season, are navigable two or three hundred miles from their mouths.

The valleys of these rivers give place to many extensive and fertile bottoms well adapted to cultivation, and producing the necessaries of life in great abundance and variety.

The plain, or rolling country, is separated from that last under consideration by the imaginary line above mentioned. It is not to be inferred, however, that the junction of these two regions is distinctly marked by any characters whatever by which the line can be traced with precision, but that a gradual change of aspect is observable in travelling from one variety of country to the other, and that the general direction of the line indicated by this change is that specified above. The other boundaries of this variety are the Mississippi on the west, and the Lakes Erie and Michigan, and the Fox and Wisconsan rivers on the north and east. This variety of country, although not entirely destitute of hills, is almost throughout its whole extent possessed of an undulating or rolling surface, rising into broad and gentle swells in some parts, and subsiding into extensive flats or plains in others. The valleys of numberless watercourses, bounded by abrupt bluffs or banks, afford some diversity to its aspect; and the bluffs in {203} particular of the principal streams, being cut by numerous ravines, contribute in many places to give the surface a hilly and broken appearance. Although no part of this region can with propriety be denominated hilly, especially when compared with the portions of country above considered, yet upon the Wisconsan, Fox, the head-waters of Rock and Melwakee rivers, the country is considerably diversified with hills, or rather swells, and valleys. The only hills worthy of particular notice, not only in this variety, but in the whole section under consideration, are the Ocooch and Smokey mountains, which are broad and elevated ridges rather than mountains. The former is situated about twelve miles north of the Wisconsan, one hundred miles above its mouth, and the latter about forty miles south of the portage between the river just mentioned and Fox river of Green Bay. The rivers of most note within this region are, the Wabash, above the hilly country before described, the Kaskaskias, Illinois, Rock and Wisconsan, tributary to the Mississippi; the Fox of Green Bay, the St. Joseph of Lake Michigan, and the Maumee and Sandusky, tributary to Lake Erie. These rivers are all navigable for boats of ten or fifteen tons burden when swollen by spring freshets; but, during the greater part of the summer and fall, they have not a sufficient depth of water for boats of burden, and in winter their navigation is entirely obstructed by ice. The spring freshets, consequent to the melting of the snow and ice, usually take place in the month of March, the southerly streams being open for navigation much earlier than those in the north.

The prairies, or champaigns, east of the Mississippi, are mostly situated in this particular region, occupying at least three fourths of it. These are waving or flat tracts of country, of greater or less extent, separated from each other by narrow skirts of woodland situated upon the margins of rivers and creeks. They are generally possessed of a rich soil, yielding {204} a spontaneous growth of grass and herbage of a luxuriant appearance. They are well adapted to the cultivation of corn, wheat, rye, barley, oats, &c. of which they yield plentiful crops.

The prevailing opinion in regard to this portion of the country, viz. that it is unhealthy, appears too well founded to admit of refutation. The causes that contribute to render it so are very obvious: a large proportion of the prairies are so flat that much of the water deposited upon them by showers remains stagnant upon the surface till it is carried off gradually by evaporation, which renders the atmosphere humid and unhealthy. The vegetable mould of which the immediate surface is composed, and the abundance of vegetables that spring and decay upon the ground, contribute largely to render these exhalations more deleterious. Although there are but few swamps or marshes, and very rarely pools of stagnant water, to be met with in this region, still the general water-table of the country is so little inclined, that the streams, having but a moderate descent, are uniformly sluggish, often exhibiting the appearance of a succession of stagnant pools. The consequence is, that the vegetable matter they contain, instead of being carried away by the strength of the current, is deposited upon the bottoms and sides of the channels, and, while in its putrescent state, serves to augment the quantity of noxious effluvia with which the atmosphere is charged.

The population of this region, compared with its extent, is very limited; and with the exception of a few villages the settlements are very scattering. Large portions of it, embracing the northerly parts of Indiana and Illinois, are almost entirely destitute of inhabitants. Many parts of the country must remain uninhabited for many years to come, on account of the scarcity of timber and other deficiencies, such as the want of mill-seats, springs of water, &c. which are serious blemishes in the character of a large {205} proportion of the country. There are, however, numerous and extensive tracts within this region possessed of a rich soil, and in other respects well adapted for settlements, and presenting the strongest inducements for emigrants to occupy them.

The country of the third order, agreeably to the subdivision above given, viz. the valley country, is situated upon the rivers, and is included within the hilly and plain country above described. The tracts belonging to this order, usually denominated bottoms, are altogether alluvial, being composed of alternate layers of sand and soil deposited from the water of the rivers upon which they are respectively situated. The alluvion thus deposited, having once constituted a part of the surface of the countries drained by the watercourses tributary to the rivers along which the deposit has been made, it will readily be inferred that the fecundity of the valleys will in some measure correspond with that of the countries whence their alluvion was derived. Accordingly we find the bottoms more or less productive in proportion to the fertility of the regions in which the rivers take their rise and through which they flow. In the valley of the Ohio the quality of the soil appears to improve from its source downwards. The alluvion, of which it is composed is supplied by the Alleghany and Monongahela rivers, which have their origin and courses in a hilly and mountainous country, possessed in general of a sandy surface. The alluvion, supplied by other tributaries entering the Ohio at various points between its source and its mouth, is of a better quality, being composed principally of argillaceous and calcareous earth, which are prevailing ingredients in the soil of the country drained by those tributaries.

It should be remarked, however, in relation to all the varieties of alluvia, that they are partially composed of the fine particles of decayed vegetable {206} matter with which the water drained from the surface of the ground is invariably charged. This property in alluvial deposits often prevails to such a degree as to render soils, apparently sandy and sterile, remarkably productive. The alluvial bottoms throughout the United States afford innumerable examples of this fact. The fertilizing matter often exhibits itself in the slimy deposits left upon the surface of the ground after an inundation.

The most extensive tract of valley country east of the Mississippi is that situated within the bluffs of this river, usually denominated the American Bottom, extending from the mouth of the Ocoa, or Kaskaskias river, northwardly to that of the Missouri. This spacious bottom, although at present elevated much above the range of the highest freshets, is nevertheless alluvial. Its length along the Mississippi is about eighty, and its average breadth about four miles. It is generally destitute of a timber growth, except along the margin of the river, upon which there is a skirt of woodland extending almost from one end of the tract to the other. The alluvion of the American Bottom is composed of the rich mud brought down by the turbid Missouri, united with an abundance of vegetable matter yielded by the waters of the upper Mississippi, which also characterizes the bottoms of this extensive river from the Missouri downward to its mouth. Upon this bottom are situated the town of Kaskaskias, the villages of Prairie de Rocher, Harrison, Prairie de Pont, Cahokia and Illinois, together with many other settlements.

On the same side of the river another large tract of valley land, called the Mississippi Bottom, commences a few miles below the mouth of the river Kaskaskias, and extends downwards along the Mississippi, between fifty and sixty miles, having an average width of about three miles. This tract, in regard {207} to soil and aspect, is of a character similar to that of the American Bottom, except that the former is more plentifully stocked with timber.
