 north, whence it rose; and, at length, after having been delayed in lakes and marshes, it flows slowly onward to the south.

Sometimes quietly gliding along the argillaceous bed which nature has assigned to it; sometimes swollen by storms, the Mississippi waters 2,500 miles in its course. At the distance of 1,364 miles from its mouth this river attains an average depth of fifteen feet; and it is navigated by vessels of 300 tuns burden for a course of nearly 500 miles. Fifty-seven large navigable rivers contribute to swell the waters of the Mississippi; among others the Missouri, which traverses a space of 2,500 miles; the Arkansas of 1,300 miles; the Red river 1,000 miles; four whose course is from 800 to 1,000 miles in length, viz: the Illinois, the St. Peter's, the St. Francis, and the Moingona; beside a countless multitude of rivulets which unite from all parts their tributary streams.

The valley which is watered by the Mississippi seems formed to be the bed of this mighty river, which like a god of antiquity dispenses both good and evil in its course. On the shores of the stream nature displays an inexhaustible fertility; in proportion as you recede from its banks, the powers of vegetation languish, the soil becomes poor, and the plants that survive have a sickly growth. Nowhere have the great convulsions of the globe left more evident traces than in the valley of the Mississippi: the whole aspect of the country shows the powerful effects of water, both by its fertility and by its barrenness. The waters of the primeval ocean accumulated enormous beds of vegetable mould in the valley, which they levelled as they retired. Upon the right shore of the river are seen immense plains, as smooth as if the husbandman had passed over them with his roller. As you approach the mountains, the soil becomes more and more unequal and steril; the ground is, as it were, pierced in a thousand places by primitive rocks, which appear like the bones of a skeleton whose flesh is partly consumed. The surface of the earth is covered with a granitic sand, and huge irregular masses of stone, among which a few plants force their growth, and give the appearance of a green field covered with the ruins of a vast edifice. These stones and this sand discover, on examination, a perfect analogy with those which compose the arid and broken summits of the Rocky mountains. The flood of waters
