Whatever faith I may have in the perfectibility of man, until human nature is altered, and men wholly transformed, I shall refuse to believe in the duration of a government which is called upon to hold together forty different peoples, disseminated over a territory equal to one-half of Europe in extent; to avoid all rivalry, ambition, and struggles between them, and to direct their independent activity to the accomplishment of the same designs.

But the greatest peril to which the Union is exposed by its increase arises from the continual changes which take place in the position of its internal strength. The distance from Lake Superior to the Gulf of Mexico extends from the 47th to the 30th degree of latitude, a distance of more than 1,200 miles as the bird flies. The frontier of the United States winds along the whole of this immense line, sometimes falling within its limits, but more frequently extending far beyond it, into the waste. It has been calculated that the whites advance every year a mean distance of seventeen miles along the whole of his vast boundary. *j Obstacles, such as an unproductive district, a lake or an Indian nation unexpectedly encountered, are sometimes met with. The advancing column then halts for a while; its two extremities fall back upon themselves, and as soon as they are reunited they proceed onwards. This gradual and continuous progress of the European race towards the Rocky Mountains has the solemnity of a providential event; it is like a deluge of men rising unabatedly, and daily driven onwards by the hand of God.

Within this first line of conquering settlers towns are built, and vast States founded. In 1790 there were only a few thousand pioneers sprinkled along the valleys of the Mississippi; and at the present day these valleys contain as many inhabitants as were to be found in the whole Union in 1790. Their population amounts to nearly 4,000,000. *k The city of Washington was founded in 1800, in the very centre of the Union; but such are the changes which have taken place, that it now stands at one of the extremities; and the delegates of the most remote Western States are already obliged to perform a journey as long as that from Vienna to Paris. *l

All the States are borne onwards at the same time in the path of fortune, but of course they do not all increase and prosper in the same proportion. To the North of the Union the detached branches of the Alleghany chain, which extend as far as the Atlantic Ocean, form spacious roads and ports, which are constantly accessible to vessels of the greatest burden. But from the Potomac to the mouth of the Mississippi the coast is sandy and flat. In this part of the Union the mouths of almost all the rivers are obstructed; and the few harbors which exist amongst these lagoons afford much shallower water to vessels, and much fewer commercial advantages than those of the North.

This first natural cause of inferiority is united to another cause proceeding from the laws. We have already seen that slavery, which is abolished in the North, still exists in the South; and I have pointed out its fatal consequences upon the prosperity of the planter himself.
