The State of Louisiana is bounded on the north by the states of Arkansas, and Mississippi; on the east by the latter and the Gulf of Mexico; on the south by the Gulf of Mexico, and on the west by Mexico and Texas. It is a well watered garden, the soil being rich, and intersected by the Mississippi, Red, and Wachita Rivers, and many inferior streams, and washed, on its western limit, by the Sabine. The face of the country is exceedingly level, so much so, that in a portion equal to three fourths of the State, there is scarcely a hill to be found. Those parts that are covered with pine woods are usually uneven, sometimes rising into fine swells, with broad table summits, intersected with valleys from thirty to forty feet deep. They do not lie in any particular range, but, like the ocean in a high and regular swell, present a uniform undulated surface. The alluvial soil is, of course level, and the swamps, which are only inundated alluvions, are dead flats. A range of gentle elevations commences in Opelousas, and gradually increasing in height as it advances, diverges toward the Sabine. In the vicinity of Natchitoches, this range holds its way northwestwardly; about half way between the Red and the Sabine Rivers, and continues to increase in altitude, till it reaches the western border of the State. Seen from the pine hills above Natchitoches, it has the blue outline and general aspect of a range of mountains. Another line of hills, commencing not far from Alexandria, on the northern side of the Red River, and separating the waters of that stream from those of the Dudgemony, extends northwardly, till it approaches, and runs into, the mammillæ, or bluffs, that bound the alluvions of the Wachita, diverging gradually from the line of that stream, as it passes beyond the western limits of the State. That remote part of Natchitoches called Allen's settlement, is a high rolling country. There are also hills of considerable magnitude on the east side of the Mississippi, beyond the alluvions. But generally speaking, Louisiana may be considered as one immense plain, divided into pine woods, prairies, alluvions, swamps, and hickory and oak lands. The pine-wood lands, as I have already said, are usually rolling. There are some exceptions, but they are very few. They have almost invariably a poor soil. Some of those west of Opelousas, and those between the Wachita and Red Rivers, are even sterile, answering well to the name by which they are called in some other parts of the country, Pine Barrens.
