The North American colonies could not have devised a measure so alarming to Great Britain, and so well calculated to force Parliament into the repeal of her obnoxious laws, as this policy of non-intercourse. It would deprive the West Indies of their ordinary supplies of provisions, and force them to suspend their usual cultivation, to produce their own food. It would cause not only the cessation of imports from Great Britain into the West Indies, on account of the inability of its people to pay, but would, at once, check all demand for slaves, both in the sugar Islands and in North America--thus creating a loss, in the African trade alone, of three and a half millions of dollars, and putting in peril one-half of the commerce of England. We are now prepared to introduce the resolutions, passed by the North American colonies, on the subject of the slave trade and slavery. It is not considered necessary to burden our pages with a repetition of the whole of the accompanying resolutions. They embraced every item of foreign commodities, excepting in a few instances where medicines, saltpetre, and other necessaries, were exempted from the prohibition. In a few counties, though they condemned the slave trade, they excepted negroes, and desired to retain the privilege of procuring them. This was in the early part of the movement. When the Continental Congress came to act upon it, no such exemption was made. On May 17, 1774, the citizens of Providence, Rhode Island, met and acquiesced in the Boston resolutions. Their proceedings closed with this declaration: "Whereas, the inhabitants of America are engaged in the preservation of their rights and liberties; and as personal liberty is an essential part of the natural rights of mankind, the deputies of the town are directed to use their endeavors to obtain an act of the General Assembly, prohibiting the importation of negro slaves in this colony; and that all negroes born in the colony should be free at a certain age." Prince George county, Virginia, June 1774, responded to Boston, and added this resolution: "_Resolved_, That the African trade is injurious to this colony, obstructs the population of it by freemen, prevents manufacturers and other useful emigrants from Europe from settling among us, and occasions an annual balance of trade against the colony."[115] Culpepper County, Virginia, July 7, 1774 acquiesced in the non-intercourse policy, and added this resolution: "_Resolved_, That the importing slaves and convict servants, is injurious to this colony, as it obstructs the population of it with freemen and useful manufacturers, and that we will not buy such slave or convict hereafter to be imported."[116] The Provincial Convention, at Charleston, South Carolina, July 6, 7, 8, 1774, resolved to acquiesce in the Boston non-intercourse measures, and the merchants agreed not to import goods or slaves, until the grievances were redressed.[117]
