cheapness of food. Suppose then that the population of Great Britain goes on increasing at its present rate, and demands every year a supply of imported food considerably beyond that of the year preceding. This annual increase in the food demanded from the exporting countries, can only be obtained either by great improvements in their agriculture, or by the application of a great additional capital to the growth of food. The former is likely to be a very slow process, from the rudeness and ignorance, of the agricultural classes in the food-exporting countries of Europe, while the British colonies and the United States are already in possession of most of the improvements yet made, so far as suitable to their circumstances. There remains as, a resource, the extension of cultivation. And on this it is to be remarked, that the capital by which any such extension can take place, is mostly still to be created. In Poland, Russia, Hungary, Spain, the increase of capital is extremely slow. In America it is rapid, but not more rapid than the population. The principal fund at present available for supplying this country with a yearly increasing importation of food, is that portion of the annual savings of America which has heretofore been applied to increasing the manufacturing establishments of the United States, and which free trade in corn may possibly divert from that purpose to growing food for our market. This limited source of supply, unless great improvements take place in agriculture, cannot be expected to keep pace with the growing demand of so rapidly increasing a population as that of Great Britain; and if our population and capital continue to increase with their present rapidity, the only mode in which food can continue to be supplied cheaply to the one, is by sending the other abroad to produce it.
§ 8.This brings us to the last of the counter-forces which check the downward tendency of profits, in a country whose capital increases faster than that of its neighbours, and whose profits are therefore nearer to the minimum. This
