fall in relation to money, that is, there would he a fall of general prices throughout the world. But if money, like other things, and in the same degree as other things, were obtained in greater abundance and cheapness, prices would be no more affected than values would: and there would be no visible sign in the state of the markets, of any of the changes which had taken place; except that there would be (if people continued to labour as much as before) a greater quantity of all sorts of commodities, circulated at the same prices by a greater quantity of money.
Improvements in production are not the only circumstance accompanying the progress of industry, which tends to diminish the cost of producing, or at least of obtaining, commodities. Another circumstance is the increase of intercourse between different parts of the world. As commerce extends, and the ignorant attempts to restrain it by tariffs become obsolete, commodities tend more and more to be produced in the places in which their production can be carried on at the least expense of labour and capital to mankind. As civilization spreads, and security of person and property becomes established, in parts of the world which have not hitherto had that advantage, the productive capabilities of those places are called into fuller activity, for the benefit both of their own inhabitants and of foreigners. The ignorance and misgovernment in which many of the regions most favoured by nature are still grovelling, afford work, probably, for many generations before those countries will be raised even to the present level of the most civilized parts of Europe. Much will also depend on the increasing migration of labour and capital to unoccupied parts of the earth, of which the soil, climate, and situation are found, by the ample means of exploration now possessed, to promise not only a large return to industry, but great facilities of producing commodities suited to the markets of old countries. Much as the collective industry of the earth is likely to be increased in efficiency by the extension of science and of the industrial
