On Rock river, the Kaskaskia, Wabash, Fox, Du Page, Macoupin and Sangamon are large tracts of first rate land. And very similar to this, are Grand prairie, Mound prairie, the Marine Settlement prairie, and the one occupied by the New-England Christians.
In the region of Sangamon river, nature has delighted to bring together her happiest combinations of landscape; being beautifully variegated with woodland and lawn, like sunshine and shade. It is generally a level country; the prairies are not too extensive, and timber abounds in sufficient quantity to support a dense population. In this beautiful section of the new world, more than two hundred families, from New-England, New-York and North Carolina, fixed their habitations before it was surveyed. The land is exceedingly rich and easily cultivated. It now constitutes a number of counties and is probably as thickly settled as any part of the State. The Sangamon itself is a fine boatable river, and has throughout its whole course, pure, transparent water and a sandy bottom. It enters the Illinois river on the easterly side, about one hundred and forty miles above its mouth.
The Kaskaskia river has a long course in the central part of the State, and the lands upon its borders are happily diversified with hill, vale, prairie and forest. On its banks are Kaskaskia, the former seat of government, and Vandalia, the present metropolis.
The region of Rock and Fox rivers is a beautiful and healthy portion of the State. The land is rich; the prairies are high, dry and gently undulating and surrounded by excellent timber. The only faults are, the prairies are too large for the quantity of timber, and there are not a sufficient number of springs and small streams of water. But it is a very pleasant and desirable portion of the country, and I believe more emigrants are now directing their course thither, than to any other portion of the State. It has one advantage over all the western section of country, it is more healthy. I believe it is as healthy as any portion of the United States.
Although there are some bodies of sterile and broken land in the State, yet as a whole, it contains a greater proportion of first rate land than any other State in the Union; and probably as great according to its extent as any country on the face of the globe. One of the inconveniences attending this extensive rich country, is too great a proportion of prairies. They cover more than half of the whole State.—But the prevalence of coal and peat, and the ease with which forest trees may be raised, will render even these extensive prairies habitable.
The original cause of these extensive prairies in all the western and southern country is altogether a matter of conjecture. There is no natural impediment in the soil to the growth of forest trees over the whole extent of the country. It is certain that the fire is the cause of continuing them in existence; for where the fire is kept out, trees spring up in them, in a few years, and their growth is vigorous and rapid.
There are many reasons for the belief, that this western country was once inhabited by a more civilized race of beings, than the present hordes of wild Indians. Specimens of fine pottery and implements of husbandry have been found in various parts of the country; and brick foundations of a large city have lately been discovered in the territory of Arkansas. These, together with the stately mounds and remains of extensive fortifications, indicate that the country was once inhabited by a race of men, who cultivated the soil for a subsistence, and were well acquainted with the mechanic arts. From whence this race of beings came, or whither they went, is alike unknown to us. Since they left, the fire has made the cleared land much more extensive. The fire, in very dry weather, and accompanied by a high wind, after scouring over the prairies, takes to the woodland and destroys the timber. Last fall, I saw hundreds of acres of woodland, so severely burnt over, that I had no doubt the trees were generally killed. But in some places, the forest gradually gains upon the prairie; and could the fire be kept within proper bounds, the western country would soon have an abundant supply of timber. But this cannot well be done. The Indian sets the prairie afire, for the conveniency of hunting—the emigrant sets it afire, so that the fresh grass may spring up for his cattle; and so between them both, they all get burnt over. And when once kindled, the fire goes where the wind happens to drive.
This State has great advantages for inland navigation by means of its rivers. On the east, it is washed by the Michigan lake and Wabash river; on the south, by the Ohio, and on the west, by the Mississippi. The most important river within the State is the Illinois. It rises near the south end of lake Michigan, runs in a southerly direction about three hundred miles, and falls into the Mississippi, thirty miles above St. Louis. Its two chief head branches are the Kankakee and Oplane; this latter river runs within twelve miles of the lake, and the space between is a low, wet prairie, so that it might easily be connected with its waters. From the north, comes in the Du Page, a larger stream than the Oplane. At Ottawa, eighty miles south of Chicago, comes in Fox river. This is by far the largest tributary of the Illinois, and at their junction is nearly equal to it in size. In all descriptions of the State, mention is hardly made of Fox river; but it is the next in size to the Illinois and Rock rivers, and is one of the most beautiful streams in the whole State. It rises in the territory west of lake Michigan, runs with a lively current, in a very straight channel, from its source to its mouth. It heads in a lake, and this accounts for the fact, that it is not, like other streams, subject to freshets. It is generally fordable—the water is not more than about three feet deep, and the bottom is sand and pebbles. It is a clear stream, abounding in fish, and withal, passes through the most healthy part of the State.
On the west side, nearly opposite Hennipen, comes in the Bureau river. This is a good mill stream, and is composed of two branches, the one called Great and the other Little Bureau; and these branches join about five miles west of the Illinois. These branches, on the maps, bear the names of Robertson's and James' river, but for what reason I know not. On this river is a large settlement of northern people, and many families from the State of New-Hampshire. Below this, the most material tributaries are the Vermillion and Sangamon from the east, and Spoon river from the west. Whatever others may say, I cannot call the Illinois a pleasant stream. It has a marsh on one side or the other from its mouth to its source, and is full of shoals and sand bars. I passed down the river in a boat that drew less than two feet water, but it often run aground. The worst bar is just below Beardstown. We had to lighten the boat of its freight, water in the boiler, and passengers, before we could pass this bar; and then, the hands had to jump into the water and push the boat over. For about two hundred miles from its mouth, it has many long and narrow lakes, of about the width of the river itself; and probably they were formerly its channel. These lakes generally have an outlet into the river, and these so much resemble it, that a person not well acquainted with the stream, would be puzzled to know what channel to take. The river occupies too much ground for its quantity of water, and for about half of the year, it is a difficult stream to navigate.
Rock river rises beyond the northern limits of the State in the high lands which separate the waters of the Mississippi from those of lake Michigan. It is a large, beautiful stream, has a lively current, and enters the Mississippi fifty miles below Galena. In the Mississippi near its mouth, is a beautiful island, on which is situated fort Armstrong.
