Warm in winter and warm in summer

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.

The North is therefore superior to the South both in commerce *m and manufacture; the natural consequence of which is the more rapid increase of population and of wealth within its borders. The States situate upon the shores of the Atlantic Ocean are already half-peopled. Most of the land is held by an owner; and these districts cannot therefore receive so many emigrants as the Western States, where a boundless field is still open to their exertions. The valley of the Mississippi is far more fertile than the coast of the Atlantic Ocean. This reason, added to all the others, contributes to drive the Europeans westward - a fact which may be rigorously demonstrated by figures. It is found that the sum total of the population of all the United States has about tripled in the course of forty years. But in the recent States adjacent to the Mississippi, the population has increased thirty-one-fold, within the same space of time. *n
