The thunder and lightning which prevail on this river are truly grand; and the sunken islands here are interesting. This effect was produced by the earthquakes, which were experienced in the west in 1811. The traveller too, on the bank of Mississippi, frequently sees huge masses of earth fall from them into the bed of the river. These masses sometimes constitute an acre, and are covered with a heavy growth of trees. The noise, occasioned by the falling of the banks, is as loud as distant thunder, {196} but far more impressive. It speaks of nature's final grave.
There are other dangers incident to the navigation of the Mississippi. The falling banks frequently crush the boats laying along side of them. Boats too, are sometimes dashed to pieces upon huge masses of wood, which, having lodged near the shore, continue to accumulate so as to produce near them a very rapid current. The fogs, which sometimes exist on this river, are so thick that one cannot see an object at the distance of fifty feet. The whirlpools in the Mississippi appear formidable; but they are not sufficiently large to endanger boats of a considerable size.
The general aspect of the country on both sides of the Mississippi, from its junction with the Ohio to the Gulf of Mexico, is perfectly level and exceedingly rich. A very few situations near the river are higher than the adjacent country, and the soil of these eminences is sandy and sterile. The timber in this part of the country, is in some places very large, but generally it is small, and apparently young. The soil here is subject to such frequent revolutions, that sufficient time is not allowed for trees to obtain their full growth. The banks of the river are not, generally, high enough to warrant settlements upon them; consequently almost the whole country, from the Ohio to Natches, is a pathless wilderness. This is
