population; nevertheless wages in the great seats of the manufacture are still so high that the collective earnings of a family amount, on an average of years, to a very satisfactory sum; and there is as yet no sign of decrease, while the effect has also been felt in raising the general standard of agricultural wages in the counties adjoining.
But those circumstances of a country, or of an occupation, in which population can with impunity increase at its utmost rate, are rare and transitory. Very few are the countries presenting the needful union of conditions. Either the industrial arts are backward and stationary, and capital therefore increases slowly, or, the effective desire of accumulation being low, the increase soon reaches its limit; or, even though both these elements are at their highest known degree, the increase of capital is checked, because there is not fresh land to be resorted to of as good quality as that already occupied. Though capital should for a time double itself simultaneously with population, if all this capital and population are to find employment on the same land, they can not, without an unexampled succession of agricultural inventions, continue doubling the produce; therefore, if wages do not fall, profits must; and, when profits fall, increase of capital is slackened.
Except, therefore, in the very peculiar cases which I have [pg 190] just noticed, of which the only one of any practical importance is that of a new colony, or a country in circumstances equivalent to it, it is impossible that population should increase at its utmost rate without lowering wages. In no old country does population increase at anything like its utmost rate; in most, at a very moderate rate: in some countries, not at all. These facts are only to be accounted for in two ways. Either the whole number of births which nature admits of, and which happen in some circumstances, do not take place; or, if they
