In the North American provinces, now the United States, negro slavery existed from a very early period, but on a very limited scale, as the demand for slaves was mainly supplied from England. The exports of the colonies were bulky, and the whites could be imported as return cargo; whereas the blacks would have required a voyage to the coast of Africa, with which little trade was maintained. The export from England ceased after the revolution of 1688, and thenceforward negro slaves were somewhat more freely imported; yet the trade appears to have been so small as scarcely to have attracted notice. The only information on the subject furnished by Macpherson in his Annals of Commerce is that, in the eight months ending July 12, 1753, the negroes imported into Charleston, S. C., were 511 in number; and that in the year 1765-66, the value of negroes imported from Africa into Georgia was £14,820--and this, if they be valued at only £10 each, would give only 1482. From 1783 to 1787, the number exported from all the West India Islands to this country was 1392 [9] --being an average of less than 300 per annum; and there is little reason for believing that this number was increased by any import direct from Africa. The British West Indies were then the entrepôt of the trade,[10] and thence they were supplied to the other islands and the settlements on the Main; and had the demand for this country been considerable, it cannot be doubted that a larger portion of the thousands then annually exported would have been sent in this direction. Under these circumstances, the only mode of arriving at the history of slavery prior to the first census, in 1790, appears to be to commence at that date and go forward, and afterwards employ the information so obtained in endeavouring to elucidate the operations of the previous period. The number of negroes, free and enslaved, at that date, was.................................... 757,263 And at the second census, in 1801, it was......... 1,001,436 showing an increase of almost thirty-three per cent. How much of this, however, was due to importation, we have now to inquire. The only two States that then tolerated the import of slaves were South Carolina and Georgia, the joint black population of which, in 1790, was............................. 136,358 whereas, in 1800, it had risen to.................. 205,555 ------- Increase.......... 69,197 =======
