Grain. Duties. Duties Duties. Beans to 28s. per qr. 19s:10d. after till 40s. 16s:8d. then 12d. Barley to 28s. - 19s:10d. - 32s. 16s. - 12d. Malt is prohibited by the annual malt-tax bill. Oats to 16s. - 5s:10d. after - 9½d. Pease to 40s. - 16s: 0d. after - 9¾d. Rye to 36s. - 19s:10d. till 40s. 16s:8d - 12d. Wheat to 44s. - 21s: 9d. till 53s:4d. 17s. - 8s. till £4, and after that about 1s:4d. Buck-wheat to 32s. per qr. to pay 16s.

These different duties were imposed, partly by the 22d of Charles II. in place of the old subsidy, partly by the new subsidy, by the one-third and two-thirds subsidy, and by the subsidy 1747. Subsequent laws still further increased those duties.

The distress which, in years of scarcity, the strict execution of those laws might have brought upon the people, would probably have been very great; but, upon such occasions, its execution was generally suspended by temporary statutes, which permitted, for a limited time, the importation of foreign corn. The necessity of these temporary statutes sufficiently demonstrates the impropriety of this general one.

These restraints upon importation, though prior to the establishment of the bounty, were dictated by the same spirit, by the same principles, which afterwards enacted that regulation. How hurtful soever in themselves, these, or some other restraints upon importation, became necessary in consequence of that regulation. If, when wheat was either below 48s. the quarter, or not much above it, foreign corn could have been imported, either duty free, or upon paying only a small duty, it might have been exported again, with the benefit of the bounty, to the great loss of the public revenue, and to the entire perversion of the institution, of which the object was to extend the market for the home growth, not that for the growth of foreign countries.

III. The trade of the merchant-exporter of corn for foreign consumption, certainly does not contribute directly to the plentiful supply of the home market. It does so, however, indirectly. From whatever source this supply maybe usually drawn, whether from home growth, or from foreign importation, unless more corn is either usually grown, or usually imported into the country, than what is usually consumed in it, the supply of the home market can never be very plentiful. But unless the surplus can, in all ordinary cases, be exported, the growers will be careful never to grow more, and the importers never to import more, than what the bare consumption of the home market requires. That market will very seldom be overstocked; but it will generally be understocked; the people, whose business it is to supply it, being generally afraid lest their goods should be left upon their hands. The prohibition of exportation limits the improvement and cultivation of the country to what the supply of its own inhabitants require. The freedom of exportation enables it to extend cultivation for the supply of foreign nations.

By the 12th of Charles II. c.4, the exportation of corn was permitted whenever the price of wheat did not exceed 40s. 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 48s. the quarter; and by the 22d, 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 1s., upon oats to 4d., and upon all other grain to 6d. the quarter. By the 1st of William and Mary, the act which established this bounty, this small duty was virtually taken off whenever the price of wheat did not exceed 48s. 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 48s. 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 48s. 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 preventive 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 be relieved by the plenty of some other. But very few countries have entirely adopted this liberal system. The freedom of the corn trade is almost everywhere more or less restrained, and in many countries is confined by such absurd regulations, as frequently aggravate the unavoidable misfortune of a dearth into the dreadful calamity of a famine. The demand of such countries for corn may frequently become so great and so urgent, that a small state in their neighbourhood, which happened at the same time to be labouring under some degree of dearth, could not venture to supply them without exposing itself to the like dreadful calamity. The very bad policy of one country may thus render it, in some measure, dangerous and imprudent to establish what would otherwise be the best policy in another. The unlimited freedom of exportation, however, would be much less dangerous in great states, in which the growth being much greater, the supply could seldom be much affected by any quantity or corn that was likely to be exported. In a Swiss canton, or in some of the little states in Italy, it may, perhaps, sometimes be necessary to restrain the exportation of corn. In such great countries as France or England, it scarce ever can. To hinder, besides, the farmer from sending his goods at all times to the best market, is evidently to sacrifice the ordinary laws of justice to an idea of public utility, to a sort of reasons of state; an act or legislative authority which ought to be exercised only, which can be pardoned only, in cases of the most urgent necessity. The price at which exportation of corn is prohibited, if it is ever to be prohibited, ought always to be a very high price.

The laws concerning corn may everywhere be compared to the laws concerning religion. The people feel themselves so much interested in what relates either to their subsistence in this life, or to their happiness in a life to come, that government must yield to their prejudices, and, in order to preserve the public tranquillity, establish that system which they approve of. It is upon this account, perhaps, that we so seldom find a reasonable system established with regard to either of those two capital objects.

IV. The trade of the merchant-carrier, or of the importer of foreign corn, in order to export it again, contributes to the plentiful supply of the home market. It is not, indeed, the direct purpose of his trade to sell his corn there; but he will generally be willing to do so, and even for a good deal less money than he might expect in a foreign market; because he saves in this manner the expense of loading and unloading, of freight and insurance. The inhabitants of the country which, by means of the carrying trade, becomes the magazine and storehouse for the supply of other countries, can very seldom be in want themselves. Though the carrying trade must thus contribute to reduce the average money price of corn in the home market, it would not thereby lower its real value; it would only raise somewhat the real value of silver.
