Those different restraints consisted sometimes in high duties, and sometimes in absolute prohibitions.
Exportation was encouraged sometimes by drawbacks, sometimes by bounties, sometimes by advantageous treaties of commerce with foreign states, and sometimes by the establishment of colonies in distant countries.
Drawbacks were given upon two different occasions. When the home manufactures were subject to any duty or excise, either the whole or a part of it was frequently drawn back upon their exportation; and when foreign goods liable to a duty were imported, in order to be exported again, either the whole or a part of this duty was sometimes given back upon such exportation.
Bounties were given for the encouragement, either of some beginning manufactures, or of such sorts of industry of other kinds as were supposed to deserve particular favour.
By advantageous treaties of commerce, particular privileges were procured in some foreign state for the goods and merchants of the country, beyond what were granted to those of other countries.
By the establishment of colonies in distant countries, not only particular privileges, but a monopoly was frequently procured for the goods and merchants of the country which established them.
The two sorts of restraints upon importation above mentioned, together with these four encouragements to exportation, constitute the six principal means by which the commercial system proposes to increase the quantity of gold and silver in any country, by turning the balance of trade in its favour. I shall consider each of them in a particular chapter, and, without taking much farther notice of their supposed tendency to bring money into the country, I shall examine chiefly what are likely to be the effects of each of them upon the annual produce of its industry. According as they tend either to increase or diminish the value of this annual produce, they must evidently tend either to increase or diminish the real wealth and revenue of the country.
CHAPTER II.
OF RESTRAINTS UPON IMPORTATION FROM FOREIGN COUNTRIES OF SUCH GOODS AS CAN BE PRODUCED AT HOME.
By restraining, either by high duties, or by absolute prohibitions, the importation of such goods from foreign countries as can be produced at home, the monopoly of the home market is more or less secured to the domestic industry employed in producing them. Thus the prohibition of importing either live cattle or salt provisions from foreign countries, secures to the graziers of Great Britain the monopoly of the home market for butcher’s meat. The high duties upon the importation of corn, which, in times of moderate plenty, amount to a prohibition, give a like advantage to the growers of that commodity. The prohibition of the importation of foreign woollen is equally favourable to the woollen manufacturers. The silk manufacture, though altogether employed upon foreign materials, has lately obtained the same advantage. The linen manufacture has not yet obtained it, but is making great strides towards it. Many other sorts of manufactures have, in the same manner obtained in Great Britain, either altogether, or very nearly, a monopoly against their countrymen. The variety of goods, of which the importation into Great Britain is prohibited, either absolutely, or under certain circumstances, greatly exceeds what can easily be suspected by those who are not well acquainted with the laws of the customs.
That this monopoly of the home market frequently gives great encouragement to that particular species of industry which enjoys it, and frequently turns towards that employment a greater share of both the labour and stock of the society than would otherwise have gone to it, cannot be doubted. But whether it tends either to increase the general industry of the society, or to give it the most advantageous direction, is not, perhaps, altogether so evident.
