that the carrying trade has been supposed peculiarly advantageous to such a country as Great Britain, of which the defence and security depend upon the number of its sailors and shipping. But the same capital may employ as many sailors and shipping, either in the foreign trade of consumption, or even in the home trade, when carried on by coasting vessels, as it could in the carrying trade. The number of sailors and shipping which any particular capital can employ does not depend upon the nature of the trade, but partly upon the bulk of the goods in proportion to their value, and partly upon the distance of the ports between which they are to be carried; chiefly upon the former of those two circumstances. The coal trade from Newcastle to London, for example, employs more shipping than all the carrying trade of England, though the ports are at no great distance. To force, therefore, by extraordinary encouragements, a larger share of the capital of any country into the carrying trade than what would naturally go to it will not always necessarily increase the shipping of that country.

The capital, therefore, employed in the home trade of any country will generally give encouragement and support to a greater quantity of productive labour in that country, and increase the value of its annual produce more than an equal capital employed in the foreign trade of consumption: and the capital employed in this latter trade has in both these respects a still greater advantage over an equal capital employed in the carrying trade. The riches, and so far as power depends upon riches, the power of every country must always be in proportion to the value of its annual produce, the fund from which all taxes must ultimately be paid. But the great object of the political economy of every country is to increase the riches and power of that country. It ought, therefore, to give no preference nor superior encouragement to the foreign trade of consumption above the home trade, nor to the carrying trade above either of the other two. It ought neither to force nor to allure into either of those two channels a greater share of the capital of the country than what would naturally flow into them of its own accord.

When the produce of any particular branch of industry exceeds what the demand of the country requires, the surplus must be sent abroad and exchanged for something for which there is a demand at home. Without such exportation a part of the productive labour of the country must cease, and the value of its annual produce diminish. The land and labour of Great Britain produce generally more corn, woollens, and hardware than the demand of the home market requires. The surplus part of them, therefore, must be sent abroad, and exchanged for something for which there is a demand at home. It is only by means of such exportation that this surplus can acquire a value sufficient to compensate the labour and expense of producing it. The neighbourhood of the sea-coast, and the banks of all navigable rivers, are advantageous situations for industry, only because they facilitate the exportation and exchange of such surplus produce for something else which is more in demand there.

When the foreign goods which are thus purchased with the surplus produce of domestic industry exceed the demand of the home market, the surplus part of them must be sent abroad again and exchanged for something more in demand at home. About ninety-six thousand hogsheads of tobacco are annually purchased in Virginia and Maryland with a part of the surplus produce of British industry. But the demand of Great Britain does not require, perhaps, more than fourteen thousand. If the remaining eighty-two thousand, therefore, could not be sent abroad and exchanged for something more in demand at home, the importation of them must cease immediately, and with it the productive labour of all those inhabitants of Great Britain, who are at present employed in preparing the goods with which these eighty-two thousand hogsheads are annually purchased. Those goods, which are part of the produce of the land and labour of Great Britain, having no market at home, and being deprived of that which they had abroad, must cease to be produced. The most round-about foreign trade of consumption, therefore may, upon some occasions, be as necessary for supporting the productive labour of the country, and the value of its annual produce, as the most direct.

When the capital stock of any country is increased to such a degree that it cannot be all employed in supplying the consumption and supporting the productive labour of that particular country, the surplus part of it naturally disgorges itself into the carrying trade, and is employed in performing the same offices to other countries. The carrying trade is the natural effect and symptom of great national wealth; but it does not seem to be the natural cause of it. Those statesmen who have been disposed to favour it
