have justified Navigation Laws, require them no longer, and afforded no reason for maintaining this invidious exception to the general rule of free trade.
With regard to subsistence, the plea of the Protectionists has been so often and so triumphantly met, that it requires little notice here. That country is the most steadily as well as the most abundantly supplied with food, which draws its supplies from the largest surface. It is ridiculous to found a general system of policy on so improbable a danger as that of being at war with all the nations of the world at once; or to suppose that, even if inferior at sea, a whole country could be blockaded like a town, or that the growers of food in other countries would not be as anxious not to lose an advantageous market, as we should be not to be deprived of their corn. On the subject, however, of subsistence, there is one point which deserves more especial consideration. In cases of actual or apprehended scarcity, many countries of Europe are accustomed to stop the exportation of food. Is this, or not, sound policy? There can be no doubt that in the present state of international morality, a people cannot, any more than an individual, be blamed for not starving itself to feed others. But if the greatest amount of good to mankind on the whole, were the end aimed at in the maxims of international conduct, such collective churlishness would certainly be condemned by them. Suppose that in ordinary circumstances the trade in food were perfectly free, so that the price in one country could not habitually exceed that in any other by more than the cost of carriage, together with a moderate profit to the importer. A general scarcity ensues, affecting all countries, but in unequal degrees. If the price rose in one country more than in others, it would be a proof that in that country the scarcity was severest, and that by permitting food to go freely thither from any other country, it would be spared from a less urgent necessity to relieve a greater. When the interests, therefore, of all countries are considered, free exportation is desirable. To the exporting
