"The annual labour of every nation is the fund which originally supplies it with all theThe the necessaries and conveniencies of life which it annually consumes and which consist alwaysnecessaries always either in the immediate produce of that labour or in what is purchased with that produce fromeither from other nations. According therefore as this produce or what is purchased with it bears a greater or smaller proportion to the number of those who are to consume it the nation will be better orsmaller or worse supplied with all the necessaries and conveniencies for which it has occasion. But this proportion must in every nation be regulated by two different circumstances: first by the skill dexterity and judgment with which its labour is generally applied; and secondly by the proportion between the number of those who are employed in useful labour and that ofby of those who are not so employed. Whatever be the soil climate or extent of territory of anythose any particular nation the abundance or scantiness of its annual supply must in that particularparticular particular situation depend upon those two circumstances."
