A tax which should have the effect of raising the price of all home productions, would not discourage exportation, except during a very limited time. If they were raised in price at home, they could not indeed immediately be profitably exported, because they would be subject to a burthen here from which abroad they were free. The tax would produce the same effect as an alteration in the value of money, which was not general and common to all countries, but confined to a single one. If England were that country, she might not be able to sell, but she would be able to buy, because importable commodities would not be raised in price. Under these circumstances nothing but money could be exported in return for foreign commodities, but this is a trade which could not long continue; a nation cannot be exhausted of its money, for after a certain quantity has left it, the value of the remainder will rise, and such a price of commodities will be the consequence, that they will again be capable of being profitably exported. When money had risen, therefore, we should no longer export it in return for goods imported, but we should export those manufactures which had first been raised in price, by the rise in the price of the raw produce from which they were made, and then again lowered by the exportation of money. But it may be objected, that when money so rose in value, it would rise with respect to foreign as well as home commodities, and therefore that all encouragement to import foreign goods would cease. Thus, suppose we imported goods which cost 100_l._ abroad, and which sold for 120_l._ here, we should cease to import them, when the value of money had so risen in England, that they would only sell for 100_l._ here: this however could never happen. The motive which determines us to import a commodity, is the discovery of its relative cheapness abroad: it is the comparison of its natural price abroad, with its natural price at home. If a country exports hats, and imports cloth, it does so because it can obtain more cloth by making hats, and exchanging them for cloth, than if it made the cloth itself. If the rise of raw produce occasions any increased cost of production in making hats, it would occasion also an increased cost in making cloth. If therefore both commodities were made at home, they would both rise. One, however, being a commodity which we import, would not rise, neither would it fall, when the value of money rose; for by not falling, it would regain its natural relation to the exported commodity. The rise of raw produce makes a hat rise from 30 to 33 shillings, or 10 per cent.: the same cause if we manufactured cloth, would make it rise from 20_s._ to 22_s._ per yard. This rise does not destroy the relation between cloth and hats; a hat was, and continues to be, worth one yard and a half of cloth. But if we import cloth, its price will continue uniformly at 20_s._ per yard, unaffected first by
