The rent of the land which affords such singular and esteemed

productions, like the rent of some vineyards in France of a

peculiarly happy soil and situation, bears no regular proportion

to the rent of other equally fertile and equally well cultivated

land in its neighbourhood. The wages of the labour, and the

profits of the stock employed in bringing such commodities to

market, on the contrary, are seldom out of their natural

proportion to those of the other employments of labour and stock

in their neighbourhood.

Such enhancements of the market price are evidently the effect of

natural causes, which may hinder the effectual demand from ever

being fully supplied, and which may continue, therefore, to

operate for ever.
