In making this calculation I have very much favoured your view of the question, because the price of corn would not, I think, rise in proportion to the greater number of men employed but to the greater amount of wages paid; it would not therefore rise to £4 16s., but to £4 4s., because as 5 : 5¼ : : £4 : £4 4s. But, if the price was only £4 4s., more corn would be required by the labourer than fourteen bushels, that calculation being founded on a greater exchangeable value of corn. It appears too that your statement if true does not account for the less proportion of the population now emp[loyed upon] the land, because you always suppose more men to [be employed] but at less corn wages. It can never happen, I think, that profits can fall and encourage the cultivation of poor [land in] the manner assumed in my table without a rise in the price of corn. It is by the rise of the price of corn that all other profits are regulated to agricultural profits. If the price of corn remained low, money wages would not rise, and general profits could not fall. If it be true that capital has become more and more productive on the land, it can, I think, only be accounted for on the supposition that great improvements have taken place in agriculture, and that wages have been kept moderate by the improvements in those manufactures which supply the poor with the necessaries on which a part of their wages are expended.
What a dreadful change in our political horizon has occurred within a few days[96]! Will it be possible to remain at peace if Bonaparte establishes himself as sovereign of France? The prospect is very gloomy.

My Dear Sir,
On no subject that we have been lately discussing have we so materially differed as on the one now occupying our attention. Your position, if established, would, I think, overturn both your theory of rent and population, for I understand you to maintain that the higher the price of corn rises, in consequence of more men being employed on the poorer land, the greater will be, not only the surplus produce after paying the labourers, but the ratio of that surplus produce to the whole capital employed on the land. If this be true there is no check to the increase of population, and food can be increased in a ratio exceeding that at which mankind increase. Your statement requires that with every additional labourer not only an equal increase but a greater increase of surplus produce should be obtained. More labourers may then be employed without limit, and rent and profit together must not only increase, but increase in a geometrical progression. I am sure I am correct in thus stating your proposition, because if as you say the whole corn expense of production per quarter will be diminished with every rise of price, the surplus must increase in a geometrical ratio with the capital employed. If you meant only that the surplus produce would increase with every accumulation of capital on the land, though in a diminishing ratio to the capital employed on the land, that is not only advanced, but strenuously maintained as the groundwork of my theory, and is the basis also on which my table is formed. You have misapprehended a passage in my last letter. I certainly never said, nor ever thought, that any good reason could be given for an increased number of men being required to produce precisely the same quantity of corn from precisely the same land. What I said was that, if at one period the number of labourers required to produce ten millions of quarters of corn was two-and-a-half millions of men, and at another, in consequence of increased demand, fifteen millions of quarters could not be produced with a portion of worse land at a less cost of labour than that of four-and-a-half millions, at this latter period a production of ten millions would require three millions of men, because fifteen is to four-and-a-half as ten to three, and if we supposed the price of corn under such circumstances to increase in the proportion of 2½ to 3, a supposition much more favourable to your view of the question than we should be obliged to concede, yet that it would not support the conclusions to which you arrive, but, on the contrary, would prove my theory to be the correct one. If the calculation had been made, as you think would have been more correct, on an increase from ten millions to ten-and-a-half millions, the result would have been the same, but we should be puzzled with the decimals or fractions which must be employed on such a supposition. I agree with you 'that the natural price of corn depends entirely upon the price of the last addition, and it does not matter whether with regard to the old land a capital yields 50 per cent. rent and profit or 20 per cent. In either case the price of corn on such land has nothing to do with the cost of production.' I do not see how the admission of this fact can assist your argument, which relates only to the ratio of the surplus produce to the whole capital employed.
I cannot conceive by what argument you could shew that it might be possible that the addition of another labourer on the land would not pay his expenses, although not more than a quarter of the population were employed upon the land. Allowing, as I most fully do, that no pressure can destroy rents, yet as the last portions of capital employed on the land pay no rent, it is to me inconceivable that there would be no inducement to employ more labourers whilst their average production should be three times more food than they could themselves consume. If the whole of this surplus, after maintaining in the most frugal manner the owners of stock, were absorbed by the landlords as rent, they would increase their revenue, and employ more labourers on the land, if any among them saved any part of his income and lent it at the common rate of interest. I am sorry you do not come to town for the next club.
Yours truly,
David Ricardo.
