If he acts consistently with that spirit of liberty, which we have supposed to animate his subjects, he has no method left, but to contrive different employments for the hands of the necessitous, that, by their labour, they may produce an equivalent which may be acceptable to the farmers, in lieu of this superfluity; for these last will certainly not raise it, if they cannot dispose of it; nor will they dispose of it, but for a proper equivalent. This is the only method (in a free state) of procuring additional food, and of distributing it through the society, as the price of those hours which before were spent in idleness: and, as this will prove a more certain and more extensive fund of subsistence, than the precarious productions of spontaneous fruits, which cannot be increased at discretion, and in proportion to demand, it will greatly increase numbers; but, on the other hand, it must evidently destroy that simplicity of manners which naturally reigns among nations who do not labour. A people, therefore, who have an industrious turn, will multiply in proportion to the superfluity of their farmers; because the labour of the necessitous will prove an equivalent for it. Now this additional number of inhabitants being raised and fed with the superfluity _actually_ produced by the farmers, can never be supposed necessary for providing that quantity, which (though relatively to the farmers it be called a superfluity) is only a sufficiency relatively to the whole society; and, therefore, if it be found necessary to employ the new inhabitants also in farming, it must only be with a view to a still greater multiplication. Farther, we may lay it down as a principle, that a farmer will not labour to produce a superfluity of grain relatively to his own consumption, unless he finds some want which may be supplied by means of that superfluity; neither will other industrious persons work to supply the wants of the farmer for any other reason than to procure subsistence, which they cannot otherwise so easily obtain. These are the reciprocal wants which the statesman must create, in order to bind the society together. Here then is one principle: _Agriculture among a free people will augment population, only in proportion as the necessitous are put in a situation to purchase subsistence with their labour_. I proceed.
