Between 1585 and 1672 inclusive, six monopolistic companies were organized in England to control the African trade. Because of the monopolistic work of the last one, the people of Barbados declared, at first, that it was "killing the provision trade from New England." That is to say, that for a time New England ships were driven from the island trade; but the smugglers soon circumvented the monopoly. "Interlopers" attempting to leave England for the slave trade were easily detained at the request of the company, but American ships were not to be so detained. Then the company appointed agents to intercept the cargoes brought to the Barbados ports, but all in vain. "Armed multitudes on foot and on horseback" attacked the unfortunate agents who tried to do their duty. Cargoes of slaves were landed on the beach between ports while agents slept. The work of the company simply increased the profits of the "interlopers." When, in 1698, Parliament opened the trade to all merchantmen, the increase of the trade was considered "so Highly Beneficial and Advantageous to this Kingdom" that efforts were made to secure the slave traffic of the Spanish islands also, and with success. The most valued feature of the Peace of Utrecht (March 13, 1713) was the Assiento by which Spain agreed to permit England to send not less than 4800 slaves every year thereafter to the Spanish colonies. With Spanish as well as all English West India islands open to the trade of the New England slavers, it is interesting to note that one port soon forged ahead of all others in the number of ships engaged in the traffic. Rhode Island merchants secured a much greater share of it than those of other parts of the coast. Their success appears to have been due in part to geographical conditions. Thus the people of Massachusetts led those of Rhode Island in the fisheries because they lived nearer the Banks, but they had no advantage in carrying forest and farm products to the West Indies. In fact, Newport was measurably nearer to Barbados than Boston was; her ships did not have to risk the dangers of Cape Cod. This was a small advantage, but all the more interesting on that account. Boston gave her attention chiefly to fish; Newport perforce made a specialty of something else, and of all the products of the soil used in trade, within her reach, there was nothing that gave so large a profit as molasses, when it was the raw material for the manufacture of rum. Newport thought to fish, at one time; a bounty was paid on whale-oil taken by ships of the colony. But the production of rum needed no artificial stimulation. Molasses cost thirteen or fourteen pennies a gallon, and Rhode Island distillers became so expert that some of them made a gallon of rum from one of molasses, though the ordinary product was 96 gallons in 100. Rum was not only cheap, it was satisfying. Even the French Canadians bought rum, instead of brandy from their native land.
