North America presents in its external form certain general features, which it is easy to discriminate at the first glance.

A sort of methodical order seems to have regulated the separation of land and water, mountains and valleys. A simple but grand arrangement is discoverable amid the confusion of objects and the prodigious variety of scenes.

 

This continent is divided, almost equally, into two vast regions, one of which is bounded, on the north by the arctic pole, and by the two great oceans on the east and west. It stretches toward the south, forming a triangle, whose irregular sides meet at length below the great lakes of Canada.

The second region begins where the other terminates, and includes all the remainder of the continent.

The one slopes gently toward the pole, the other toward the equator.

The territory comprehended in the first regions descends toward the north with so imperceptible a slope that it may almost be said to form a level plain. Within the bounds of this immense tract of country there are neither high mountains nor deep valleys. Streams meander through it irregularly; great rivers mix their currents, separate and meet again, disperse and form vast marshes, losing all trace of their channels in the labyrinth of waters they have themselves created; and thus, at length, after innumerable windings, fall into the polar seas. The great lakes which bound this first region are not walled in, like most of those in the Old World, between hills and rocks. Their banks are flat, and rise but a few feet above the level of their waters; each of them thus forming a vast bowl filled to the brim. The slightest change in the structure of the globe would cause their waters to rush either toward the pole or to the tropical sea.

The second region is more varied on its surface, and better suited for the habitation of man. Two long chains of mountains divide it from one extreme to the other; the Allegany ridge takes the form of the shores of the Atlantic ocean; the other is parallel with the Pacific.

The space which lies between these two chains of mountains contains 1,341,649 square miles.[3] Its surface is therefore about six times as great as that of France.

This vast territory, however, forms a single valley, one side of which descends gradually from the rounded summits of the Alleganies, while the other rises in an uninterrupted course toward the tops of the Rocky mountains.

At the bottom of the valley flows an immense river, into which the various streams issuing from the mountains fall from all parts. In memory of their native land, the French formerly called this the river St. Louis. The Indians, in their pompous language, have named it the Father of Waters, or the Mississippi.

The Mississippi takes its source above the limit of the two great regions of which I have spoken, not far from the highest point of the table-land where they unite. Near the same spot rises another river,[4] which empties itself into the polar seas. The course of the Mississippi is at first devious: it winds several times toward the 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.[5] 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 tons 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 1000 miles in length, viz., the Illinois, the St. Peter's, the St. Francis, and the Moingona; besides a countless number of rivulets which unite from all parts their tributary streams.
