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 favor.
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 favor. I shall consider each of them in a particular chapter, and without taking much further 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.
