Arkansas territory exhibits every variety and quality of soil. The cultivated belt below the Post of Arkansas bears some outward resemblance to the _coast_ in Louisiana; though its soil is not so fertile, and needs manuring to produce large crops. Large prairies interspersed with forest bottoms, and large tracts of excellent soil, are found five or six hundred miles from the mouth of Arkansas river. Mount Prairie, which lies on the Washita, has a black soil of extreme richness. On the White river are some of the healthiest and most fertile situations in this country. The other parts of this territory are vast tracts of sterile and precipitous ridges, sandy prairies, and barrens. The soil of Tennessee, in the valleys of its creeks and streams, is rich beyond any of the same description elsewhere in the western country. In East Tennessee it derives its fertility from the quantities of dissolved lime, and nitrate of lime that are mixed with it. In West Tennessee the strata are arranged in the following order: first, a loamy soil, or mixtures of clay and sand; next, yellow clay; then comes a mixture of red sand and red clay; and lastly, a white sand. In the southern parts of this state immense banks are found of uncommonly large oyster shells, situated on high table-grounds remote from any water-course. Missouri contains a large proportion of friable, loamy, and sandy soil. The uplands are rich, and of a darkish gray color: excepting the region of the lead mines, where the soil is bright and reddish. The prairies are generally level, and of an intermediate character between the rich and the poorer uplands, the latter of which have a light, yellow soil, stiff and clayey. The bottoms of the great rivers and smaller streams of this state have uncommon fertility. On the upper Mississippi are rich uplands, interspersed with flinty knobs two or three hundred feet high. In the south-west part of the state are sterile tracts, covered with yellow pine, and scattered with hilly and rocky country. Kentucky abounds in large bodies of fertile land, but even here are tracts too sterile for cultivation. Nothing can exceed in richness the great valley of which Lexington is the centre. A tract one hundred miles by fifty in extent is found in the centre of the state, with a substratum of limestone, which dissolves and so mingles with the soil as to impart to it great richness and vigor. Much of the soil is of that character known as mulatto land. An extensive tract of barrens occurs between the Rolling Fork and Green river, and between the latter and Cumberland river, in the northern and eastern parts of the state. Here the soil is generally good, and affords fine pasturage.
