Every increase in the real wealth of the society, every increase

in the quantity of useful labour employed within it, tends

indirectly to raise the real rent of land. A certain proportion

of this labour naturally goes to the land. A greater number of

men and cattle are employed in its cultivation, the produce

increases with the increase of the stock which is thus employed

in raising it, and the rent increases with the produce.

The contrary circumstances, the neglect of cultivation and

improvement, the fall in the real price of any part of the rude

produce of land, the rise in the real price of manufactures from

the decay of manufacturing art and industry, the declension of

the real wealth of the society, all tend, on the other hand, to

lower the real rent of land, to reduce the real wealth of the

landlord, to diminish his power of purchasing either the labour,

or the produce of the labour, of other people.
