its importation by the comparative facility of its production in those countries.
How then can it be true, that "if you except corn, and such other vegetables, as are raised altogether by human industry, all other sorts of rude produce—cattle, poultry, game of all kinds, the useful fossils and minerals of the earth, &c., naturally grow dearer as the society advances." Why should corn and vegetables alone be excepted? Dr. Smith's error throughout his whole work, lies in supposing that the value of corn is constant; that though the value of all other things may, the value of corn never can be raised. Corn, according to him, is always of the same value, because it will always feed the same number of people. In the same manner it might be said, that cloth is always of the same value, because it will always make the same number of coats. What can value have to do with the power of feeding and clothing?
Corn, like every other commodity, has in every country its natural price, viz. that price which is necessary to its production, and without which it could not be cultivated: it is this price which governs its market price, and which determines the expediency of exporting it to foreign countries. If the importation of corn were prohibited in England, its natural price might rise to 6l. per quarter in England, whilst it was only at half that price in France. If at this time, the prohibition of importation were removed, corn would fall in the English market, not to a price between 6l. and 3l., but ultimately and permanently to the natural price of France, the price at which it could be furnished to the English market, and afford the usual and ordinary profits of stock in France; and it would remain at this price, whether England consumed a hundred thousand, or a million of quarters. If the demand of England were for the latter quantity, it is probable that, owing to the necessity under which France would be, of having recourse to land of a worse quality, to furnish this large supply, the natural price would rise in France; and this would of course affect also the price of corn in England. All that I contend for is, that it is the
