The Wealth of Nations_ Books 4-5 - Adam Smith [93]
By the 12th of Charles II. c. 4, the exportation of corn was permitted whenever the price of wheat did not exceed forty shillings the quarter, and that of other grain in proportion. By the 15th of the same prince, this liberty was extended till the price of wheat exceeded forty-eight shillings the quarter; and by the 22nd, to all higher prices. A poundage, indeed, was to be paid to the king upon such exportation. But all grain was rated so low in the book of rates that this poundage amounted only upon wheat to a shilling, upon oats to fourpence, and upon all other grain to sixpence the quarter. By the 1st of William and Mary, the act which established the bounty, this small duty was virtually taken off whenever the price of wheat did not exceed forty-eight shillings the quarter; and by the 11th and 12th of William III. c. 20, it was expressly taken off at all higher prices.
The trade of the merchant exporter was, in this manner, not only encouraged by a bounty, but rendered much more free than that of the inland dealer. By the last of these statutes, corn could be engrossed at any price for exportation, but it could not be engrossed for inland sale except when the price did not exceed forty-eight shillings the quarter. The interest of the inland dealer, however, it has already been shown, can never be opposite to that of the great body of the people. That of the merchant exporter may, and in fact sometimes is. If, while his own country labours under a dearth, a neighbouring country should be afflicted with a famine, it might be his interest to carry corn to the latter country in such quantities as might very much aggravate the calamities of the dearth. The plentiful supply of the home market was not the direct object of those statutes; but, under the pretence of encouraging agriculture, to raise the money price of corn as high as possible, and thereby to occasion, as much as possible, a constant dearth in the home market. By the discouragement of importation, the supply of that market, even in times of great scarcity, was confined to the home growth; and by the encouragement of exportation, when the price was so high as forty-eight shillings the quarter, that market was not, even in times of considerable scarcity, allowed to enjoy the whole of that growth. The temporary laws, prohibiting for a limited time the exportation of corn, and taking off for a limited time the duties upon its importation, expedients to which Great Britain has been obliged so frequently to have recourse, sufficiently demonstrate the impropriety of her general system. Had that system been good, she would not so frequently have been reduced to the necessity of departing from it.
Were all nations to follow the liberal system of free exportation and free importation, the different states into which a great continent was divided would so far resemble the different provinces of a great empire. As among the different provinces of a great empire the freedom of the inland trade appears, both from reason and experience, not only the best palliative of a dearth, but the most effectual preventative of a famine; so would the freedom of the exportation and importation trade be among the different states into which a great continent was divided. The larger the continent, the easier the communication through all the different parts of it, both by land and by water, the less would any one particular part of it ever be exposed to either of these calamities, the scarcity of any one country being more likely to
