In all great countries the greater part of the cultivated lands are employed in producing either food for men or food for cattle. The rent and profit of these regulate the rent and profit of all other cultivated land. If any particular produce afforded less, the land would soon be turned into corn or pasture; and if any afforded more, some part of the lands in corn or pasture would soon be turned to that produce.
Those productions, indeed, which require either a greater original expense of improvement, or a greater annual expense of cultivation, in order to fit the land for them, appear commonly to afford, the one a greater rent, the other a greater profit than corn or pasture. This superiority, however, will seldom be found to amount to more than a reasonable interest or compensation for this superior expense.
In a hop garden, a fruit garden, a kitchen garden, both the rent of the landlord, and the profit of the farmer, are generally greater than in a corn or grass field. But to bring the ground into this condition requires more expense. Hence a greater rent becomes due to the landlord. It requires too a more attentive and skilful management. Hence a greater profit becomes due to the farmer. The crop too, at least in the hop and fruit garden, is more precarious. Its price, therefore, besides compensating all occasional losses, must afford something like the profit of insurance. The circumstances of gardeners, generally mean, and always moderate, may satisfy us that their great ingenuity is not commonly over-recompenced. Their delightful art is practised by so many rich people for amusement, that little advantage is to be made by those who practise it for profit; because the persons who should naturally be their best customers, supply themselves with all their most precious productions.
