the north; and the African race has causes of increase in the south very analogous to those which so powerfully accelerate the growth of the European race in the north.
In the state of Maine there is one negro in three hundred inhabitants; in Massachusetts, one in one hundred; in New York, two in one hundred; in Pennsylvania, three in the same number; in Maryland, thirty-four; in Virginia, forty-two; and lastly, in South Carolina, fifty-five per cent.[251] Such was the proportion of the black population to the whites in the year 1830. But this proportion is perpetually changing, as it constantly decreases in the north and augments in the south.
It is evident that the most southern states of the Union cannot abolish slavery without incurring very great dangers, which the north had no reason to apprehend when it emancipated its black population. We have already shown the system by which the northern states secure the transition from slavery to freedom, by keeping the present generation in chains, and setting their descendants free; by this means the negroes are gradually introduced into society; and while the men who might abuse their freedom are kept in a state of servitude, those who are emancipated may learn the art of being free before they become their own masters. But it would be difficult to apply this method in the south. To declare that all the negroes born after a certain period shall be free, is to introduce the principle and the notion of liberty into the heart of slavery; the blacks, whom the law thus maintains in a state of slavery from which their children are delivered, are astonished at so unequal a fate, and their astonishment is only the prelude to their impatience and irritation. Thenceforward slavery loses in their eyes that kind of moral power which it derived from time and habit; it is reduced to a mere palpable abuse of force. The northern states had nothing to fear from the contrast, because in them the blacks were few in number, and the white population was very considerable. But if this faint dawn of freedom were to show two millions of men their true position, the oppressors would have reason to tremble. After having enfranchised the children of their slaves, the Europeans of the southern states would very shortly be obliged to extend the same benefit to the whole black population.
In the north, as I have already remarked, a two-fold migration ensues upon the abolition of slavery, or even precedes that event when circumstances have rendered it probable; the slaves quit the country to be transported southward; and the whites of the northern states as well as the emigrants from Europe hasten to fill up their place. But these two causes cannot operate in the same manner in the southern states. On the one hand, the mass of slaves is too great for any expectation of their ever being removed from the country to be entertained; and on the other hand, the Europeans and the Anglo-Americans of the north are afraid to come to inhabit a country, in which labor has not yet been reinstated in its rightful honors. Besides, they very justly look upon the states in which the proportion of the negroes equals or exceeds that of the whites, as exposed to very great dangers; and they refrain from turning their activity in that direction.
Thus the inhabitants if the south would not be able, like their northern countrymen, to initiate the slaves gradually into a state of freedom, by abolishing slavery; they have no means of perceptibly diminishing the black population, and they would remain unsupported to repress its excesses. So that in the course of a few years, a great people of free negroes would exist in the heart of a white nation of equal size.
