NATCHEZ--MIZEZIBBEE; OR, THE PARENT OF MANY WATERS--INDIAN MOUNDS--THE CHILD OF THE SUN--TREATMENT OF THE FEMALES--POETIC MARRIAGES--UNCHASTE MAIDS AND PURE WIVES--WALKING ARCHIVES--THE PROFANE FIRE--ALAHOPLECHIA --OYELAPE--THE CHIEF WITH A BEARD. The little city of Natchez is built upon a bluff some three hundred feet in elevation above the Mississippi River, and immediately upon its brink. It receives its name from a tribe of Indians once resident in the country; and who were much further advanced in civilization than their more warlike neighbors, the Choctaws and the Chickasaws. The country around is hilly and beautiful, fertile and salubrious. The population was intelligent and refined, and was remarkable for having more wealth than any community outside of a large city, in the United States, of the same amount of population. The town of Natchez (for, properly speaking, it is no more) consists of some three or four thousand inhabitants, and has not increased to any considerable extent, for many years. Beyond the river, in Louisiana, is an alluvial plain extending for fifty miles, through which meander many small streams, or bayous, as they are termed in the language of the country. Upon most of these the surface of the soil is slightly elevated above the plane of the swamp, and is remarkably fertile. Most of these were, at the commencement of the late war, in a high state of cultivation as cotton plantations. As in many other places, the river here has changed its bed by cutting off a large bend immediately opposite the town, creating what is known as Lake Concordia. This lake was formerly the bed of the river, and describes almost a complete circle of some twelve miles in diameter. On both sides of this lake beautiful plantations, with splendid improvements, presented a view from the bluff at Natchez extremely picturesque when covered with luxuriant crops of corn and cotton. The fertility of the soil is such that these crops are immensely heavy; and when the cotton-plant has matured its fruit, and the pent-up lint in the large conical balls has burst them open, exposing their white treasure swelling out to meet the sun's warm rays, and the parent stock to the first frost of autumn has thrown off her foliage, and all these broad fields are one sheet of lovely white, as far as the eye can view--the scene is lovely beyond description; and when the same rich scene was presented extending along the banks of the great river, with the magnificent steamers resting at the wharf below, and others cleaving the current in proud defiance of the mighty volume of hurrying waters--the splendor and magnificence of the whole sublimated the feelings as we viewed it in wonder.
