In a previous chapter it has been shown how climatic and industrial laws govern our mixed populations, and, without the slightest interference of government, the negro element goes just where its own welfare as well as that of the white citizenship and the general interests of civilization demand its presence. This law of industrial adaptation has carried it from northern ports into the Central States, from the latter to the Border States, and is now, with even increased activity, carrying it from Virginia, etc., into the Gulf States, and thus permitted to go on, with all obstacles removed from the path of its progress, a time will come when the negro population of the New World will be within the centre of existence where it was created, and where the Almighty Creator has provided for its well-being. A sectional party in the North, taking advantage of popular ignorance, and actually enacting a law prohibiting it to exist anywhere where white labor is best adapted, could not by that sole act do any practical injury to the social order of the South. Such an act would indeed be a violation of the spirit of the federal compact, and, as an adjunct of the hostile policy of the foreign enemies of republican institutions, its moral bearings would be full of mischief; but, disconnected or disunited with the British free negro policy, it would be harmless, for, as Mr. Webster once declared, it would only be a “reënactment of the will of God.” But, as already observed, the danger of this whole question lies beyond the boundaries of the American Union, and if it be true that we have a considerable number in our midst disaffected to democratic institutions—then every man opposed to the existing condition, or so-called slavery, is, however ignorant of it, to a certain extent an instrument of the enemies of these institutions; and the policy of any such party, as well as the action of any among us, whether in concert with, or independently of any such party, for the same common object or end, becomes treason, and treason the most wicked and revolting that the mind can conceive of, for it involves the natural supremacy of the white man over the negro, as well as the permanence, peace, and prosperity of our republican system. The Spanish, still less the Portuguese conquerors of America, have never exhibited that healthy natural instinct which preserves the integrity of races, so universally as the Anglo-Americans have done. They have intermixed and amalgamated with the Indians or Aboriginals with little hesitation; and though they have always manifested a certain repugnance to an equality with the still more subordinate negro, they have largely intermixed, and therefore, extensively deteriorated and ruined themselves.
