Many white servants were thus encouraged to settle in the colony; but so much larger was the influx of black slaves that the colony, in 1760, totally prohibited the slave-trade. This act was promptly disallowed by the Privy Council and the governor reprimanded;[18] but the colony declared that "an importation of negroes, equal in number to what have been imported of late years, may prove of the most dangerous consequence in many respects to this Province, and the best way to obviate such danger will be by imposing such an additional duty upon them as may totally prevent the evils."[19] A prohibitive duty of L100 was accordingly imposed in 1764.[20] This duty probably continued until the Revolution. The war made a great change in the situation. It has been computed by good judges that, between the years 1775 and 1783, the State of South Carolina lost twenty-five thousand Negroes, by actual hostilities, plunder of the British, runaways, etc. After the war the trade quickly revived, and considerable revenue was raised from duty acts until 1787, when by act and ordinance the slave-trade was totally prohibited.[21] This prohibition, by renewals from time to time, lasted until 1803. 6. ~Restrictions in North Carolina.~ In early times there were few slaves in North Carolina;[22] this fact, together with the troubled and turbulent state of affairs during the early colonial period, did not necessitate the adoption of any settled policy toward slavery or the slave-trade. Later the slave-trade to the colony increased; but there is no evidence of any effort to restrict or in any way regulate it before 1786, when it was declared that "the importation of slaves into this State is productive of evil consequences and highly impolitic,"[23] and a prohibitive duty was laid on them. 7. ~Restrictions in Virginia.~[24] Next to South Carolina, Virginia had probably the largest slave-trade. Her situation, however, differed considerably from that of her Southern neighbor. The climate, the staple tobacco crop, and the society of Virginia were favorable to a system of domestic slavery, but one which tended to develop into a patriarchal serfdom rather than into a slave-consuming industrial hierarchy. The labor required by the tobacco crop was less unhealthy than that connected with the rice crop, and the Virginians were, perhaps, on a somewhat higher moral plane than the Carolinians. There was consequently no such insatiable demand for slaves in the larger colony. On the other hand, the power of the Virginia executive was peculiarly strong, and it was not possible here to thwart the slave-trade policy of the home government as easily as elsewhere.
