And in like manner they will not disturb, trouble, or molest any persons, whomsoever, who, under any title or in any way or manner whatsoever, shall trade or traffic in or acquire the said merchandise or trade of Guinea, or the said lands, shores or coasts, discovered or to be discovered, in the name or under the authority of the said
