If however Poland should be the first to improve her manufactures, if she should succeed in making a commodity which was generally desirable, including great value in little bulk, or if she should be exclusively blessed with some natural production, generally desirable, and not possessed by other countries, she would obtain an additional quantity of gold in exchange for this commodity, which would operate on the price of her corn, cattle, and coarse clothing. The disadvantage of distance would probably be more than compensated by the advantage of having an exportable commodity of great value, and money would be permanently of lower value in Poland than in England. If on the contrary, the advantage of skill and machinery were possessed by England, another reason would be added to that which before existed, why gold should be less valuable in England than in Poland, and why corn, cattle, and clothing, should be at a higher price in the former country.
These I believe to be the only two causes which regulate the comparative value of money in the different countries of the world; for although taxation occasions a disturbance of the equilibrium of money, it does so by depriving the country in which it is imposed of some of the advantages attending skill, industry, and climate.
It has been my endeavour carefully to distinguish between a low value of money, and a high value of corn, or any other commodity with which money may be compared. These have been generally considered as meaning the same thing; but it is evident, that when corn rises from five to ten shillings a bushel, it may be owing either to a fall in the value of money, or to a rise in the value of corn. Thus we have seen, that from the necessity of having recourse successively to land of a worse and worse quality, in order to feed an increasing population, corn must rise in relative value to other things. If therefore money continue permanently
