The advantages of such colonies to their respective mother countries, consist altogether in those peculiar advantages which are supposed to result from provinces of so very peculiar a nature as the European colonies of America; and the exclusive trade, it is acknowledged, is the sole source of all those peculiar advantages.
In consequence of this exclusive trade, all that part of the surplus produce of the English colonies, for example, which consists in what are called enumerated commodities, can be sent to no other country but England. Other countries must afterwards buy it of her. It must be cheaper, therefore, in England than it can be in any other country, and must contribute more to increase the enjoyments of England than those of any other country. It must likewise contribute more to encourage her industry. For all those parts of her own surplus produce which England exchanges for those enumerated commodities, she must get a better price than any other countries can get for the like parts of theirs, when they exchange them for the same commodities. The manufactures of England, for example, will purchase a greater quantity of the sugar and tobacco of her own colonies than the like manufactures of other countries can purchase of that sugar and tobacco. So far, therefore, as the manufactures of England and those of other countries are both to be exchanged for the sugar and tobacco of the English colonies, this superiority of price gives an encouragement to the former beyond what the latter can, in these circumstances, enjoy. The exclusive trade of the colonies, therefore, as it diminishes, or at least keeps down below what they would otherwise rise to, both the enjoyments and the industry of the countries which do not possess it, so it gives an evident advantage to the countries which do possess it over those other countries.
