arts, a still more active source of increased cheapness of production will be found, probably, for some time to come, in the gradually unfolding consequences of Free Trade, and in the increasing scale on which Emigration and Colonization will be carried on.
From the causes now enumerated, unless counteracted by others, the progress of things enables a country to obtain at less and less of real cost, not only its own productions but those of foreign countries. Indeed, whatever diminishes the cost of its own productions, when of an exportable character, enables it, as we have already seen, to obtain its imports at less real cost.
§ 2.But is it the fact, that these tendencies are not counteracted? Has the progress of wealth and industry no effect in regard to cost of production, but to diminish it? Are no causes of an opposite character brought into operation by the same progress, sufficient in some cases not only to neutralize, but to overcome the former, and convert the descending movement of cost of production into an ascending movement? We are already aware that there are such causes, and that, in the case of the most important classes of commodities, food and materials, there is a tendency diametrically opposite to that of which we have been speaking. The cost of production of these commodities tends to increase.
This is not a property inherent in the commodities themselves. If population were stationary, and the produce of the earth never needed to be augmented in quantity, there would be no cause for greater cost of production. Mankind would, on the contrary, have the full benefit of all improvements in agriculture, or in the arts subsidiary to it, and there would be no difference, in this respect, between the products of agriculture and those of manufactures. The only products of industry, which, if population did not increase, would be liable to a real increase of cost of production, are those which, depending on a material which is not renewed, are either
