INTRODUCTION AND PLAN OF THE WORK.
The annual labour of every nation is the fund which originally
supplies it with all the necessaries and conveniencies of life which
it annually consumes, and which consist always either in the immediate
produce of that labour, or in what is purchased with that produce from
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 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 of those who are not so employed. Whatever be the soil, climate,
or extent of territory of any particular nation, the abundance or
scantiness of its annual supply must, in that particular situation,
depend upon those two circumstances.
