Africa was made dutiable at the rate of five ounces of “Sivil pillar or Mexican plate” or forty shillings in bills of credit current in the colony; and for every such slave imported from all other places by land or water, the sum of £4 in like money was exacted.[867] All slaves belonging to the crew of any vessel, and slaves coming into the colony from the neighboring colonies upon the service of their masters, and all slaves under fourteen years of age were to be admitted free of duty.[868] Any person coming into the colony alone, or with his or her family to reside or visit in the colony, was allowed to bring slaves for personal service, provided the owner gave sufficient security to the treasurer within four days after the importation thereof, that, whenever such slaves should be sold, the duty imposed by the act should be paid within two days after such sale. Upon failure to pay such duty, the owner or disposer of such slaves was to forfeit the sum of £10, the slave or slaves, nevertheless, to be subject to the duty in question. The duties provided for by the act were to remain in existence for the period of one year.[869] At the expiration of the act it was continued for another year, with certain amendments which did not relate to slaves.[870] At the expiration of the specified period it was again continued for another year or until the close of 1740,[871] when it was again continued until December, 1741.[872] Such acts were then passed by New York each year until the opening of the troubles of the Revolutionary period.[873] The number of Indians exported as slaves from South Carolina was larger than that from any other colony. As a means of obtaining revenue, as well as of attempting to check the business of the Indian traders, the colony passed an act in 1703 which placed a duty upon Indian slaves exported from the colony.[874] The traders were carefully instructed not to attempt any such exportations without first paying at Charleston the required duties, twenty shillings for each Indian exported[875].
