94. ~The Political Movement.~ The political efforts to limit the slave-trade were the outcome partly of moral reprobation of the trade, partly of motives of expediency. This legislation was never such as wise and powerful rulers may make for a nation, with the ulterior purpose of calling in the respect which the nation has for law to aid in raising its standard of right. The colonial and national laws on the slave-trade merely registered, from time to time, the average public opinion concerning this traffic, and are therefore to be regarded as negative signs rather than as positive efforts. These signs were, from one point of view, evidences of moral awakening; they indicated slow, steady development of the idea that to steal even Negroes was wrong. From another point of view, these laws showed the fear of servile insurrection and the desire to ward off danger from the State; again, they often indicated a desire to appear well before the civilized world, and to rid the "land of the free" of the paradox of slavery. Representing such motives, the laws varied all the way from mere regulating acts to absolute prohibitions. On the whole, these acts were poorly conceived, loosely drawn, and wretchedly enforced. The systematic violation of the provisions of many of them led to a widespread belief that enforcement was, in the nature of the case, impossible; and thus, instead of marking ground already won, they were too often sources of distinct moral deterioration. Certainly the carnival of lawlessness that succeeded the Act of 1807, and that which preceded final suppression in 1861, were glaring examples of the failure of the efforts to suppress the slave-trade by mere law. 95. ~The Economic Movement.~ Economic measures against the trade were those which from the beginning had the best chance of success, but which were least tried. They included tariff measures; efforts to encourage the immigration of free laborers and the emigration of the slaves; measures for changing the character of Southern industry; and, finally, plans to restore the economic balance which slavery destroyed, by raising the condition of the slave to that of complete freedom and responsibility. Like the political efforts, these rested in part on a moral basis; and, as legal enactments, they were also themselves often political measures. They differed, however, from purely moral and political efforts, in having as a main motive the economic gain which a substitution of free for slave labor promised.
