Note 53 — Chapter XXIX

Inquiry, &c. "In all progressive countries, the average price of corn is never higher than what is necessary to continue the average increase of produce." Observations, p. 21.

"In the employment of fresh capital upon the land, to provide for the wants of an increasing population, whether this fresh capital is employed in bringing more land under the plough, or improving land already in cultivation, the main question always depends upon the expected returns of this capital; and no part of the gross profits can be diminished, without diminishing the motive to this mode of employing it. Every diminution of price, not fully and immediately balanced by a proportioned fall in all the necessary expenses of a farm, every tax on the land, every tax on farming stock, every tax on the necessaries of farmers, will tell in the computation; and if, after all these outgoings are allowed for, the price of the produce will not leave a fair remuneration for the capital employed, according to the general rate of profits, and a rent at least equal to the rent of the land in its former state, no sufficient motive can exist to undertake the projected improvement." Observations, p. 22.
