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 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 of corn that was
