The Wealth of Nations_ Books 4-5 - Adam Smith [295]
That system has come gradually more and more into fashion. The old subsidy was imposed indifferently upon exportation as well as importation. The four subsequent subsidies, as well as the other duties which have since been occasionally imposed upon particular sorts of goods have, with a few exceptions, been laid altogether upon importation. The greater part of the ancient duties which had been imposed upon the exportation of the goods of home produce and manufacture have either been lightened or taken away altogether. In most cases they have been taken away. Bounties have even been given upon the exportation of some of them. Drawbacks too, sometimes of the whole, and, in most cases, of a part of the duties which are paid upon the importation of foreign goods, have been granted upon their exportation. Only half the duties imposed by the old subsidy upon importation are drawn back upon exportation: but the whole of those imposed by the latter subsidies and other imposts are, upon the greater part of goods, drawn back in the same manner. This growing favour of exportation, and discouragement of importation, have suffered only a few exceptions, which chiefly concern the materials of some manufactures. These our merchants and manufacturers are willing should come as cheap as possible to themselves, and as dear as possible to their rivals and competitors in other countries. Foreign materials are, upon this account, sometimes allowed to be imported duty free; Spanish wool, for example, flax, and raw linen yarn. The exportation of the materials of home produce, and of those which are the particular produce of our colonies, has sometimes been prohibited, and sometimes subjected to higher duties. The exportation of English wool has been prohibited. That of beaver skins, of beaver wool, and of gum Senega has been subjected to higher duties; Great Britain, by the conquest of Canada and Senegal, having got almost the monopoly of those commodities.
That the mercantile system has not been very favourable to the revenue of the great body of the people, to the annual produce of the land and labour of the country, I have endeavoured to show in the fourth book of this Inquiry. It seems not to have been more favourable to the revenue of the sovereign, so far at least as that revenue depends upon the duties of customs.
In consequence of that system, the importation of several sorts of goods has been prohibited altogether. This prohibition has in some cases entirely prevented, and in others has very much diminished the importation of those commodities by reducing the importers to the necessity of smuggling. It has entirely prevented the importation of foreign woollens, and it has very much diminished that of foreign silks and velvets. In both cases it has entirely annihilated the revenue of customs which might have been levied upon such importation.
The high duties which have been imposed upon the importation of many different sorts of foreign goods, in order to discourage their consumption in Great Britain, have in many cases served only to encourage smuggling, and in all cases have reduced the revenue of the customs below what more moderate
