"The _Valley of the Ohio_ is better known than any of the others; has much fertile land, and much that is sterile, or unfit for cultivation, on account of its unevenness. It is divided into two unequal portions, by the Ohio river; leaving on the right or northwest side 80,000, and on the left or southeast side, 116,000 square miles. The eastern part of this valley is hilly, and rapidly acclivous towards the Appalachian mountains. Indeed its high hills, as you approach these mountains, are of a strongly marked mountainous character. Of course the rivers which flow into the Ohio--the Monongahela, Kenhawa, Licking, Sandy, Kentucky, Green, Cumberland, and Tennessee--are rapid, and abounding in cataracts and falls, which, towards their sources, greatly impede navigation. The western side of this Valley is, also, hilly for a considerable distance from the Ohio, but towards its western limit, it subsides to a remarkably level region. So that whilst the eastern line of this Valley lies along the high table land, on which the Appalachian mountains rest, and where the rivers of the eastern section of this Valley rise, which is at least 2,000 miles generally above the ocean level; the western line has not an elevation of much more than half of that amount on the north, and which greatly subsides towards the Kaskaskia. The rivers of the western section are Beaver, Muskingum, Hockhocking, Scioto, Miami, and Wabash. Along the Ohio, on each side, are high hills, often intersected with deep ravines, and sometimes openings of considerable extent, and well known by the appellation of "Ohio hills." Towards the mouth of the Ohio, these hills almost wholly disappear, and extensive level bottoms, covered with heavy forests of oak, sycamore, elm, poplar, and cotton wood, stretch along each side of the river. On the lower section of the river, the water, at the time of the spring floods, often overflows these bottoms to a great extent. This fine Valley embraces considerably more than one half of the whole population of the entire Valley of the West. The western parts of Pennsylvania and Virginia, the entire states of Ohio, Indiana, and Kentucky, the larger part of Tennessee, and a smaller part of Illinois, are in the Valley of the Ohio."
