portion of land abandoned will be the least fertile portion, the price of produce will thenceforth be regulated by a better quality of land than before. In addition, therefore, to the original diminution of one-tenth in the cost of production, there will be a further diminution, corresponding with the recession of the " margin" of agriculture to land of greater fertility. There will thus be a twofold fall of price.
Let us now examine the effect of the improvements, thus suddenly made, on the division of the produce; and in the first place, on rent. By the former of the two kinds of improvement, rent would be diminished. By the second, it would be diminished still more.
Suppose that the demand for food requires the cultivation of three qualities of land, yielding, on an equal surface, and at an equal expense, 100, 80, and 60 bushels of wheat. The price of wheat will, on the average, be just sufficient to enable the third quality to be cultivated with the ordinary profit. The first quality therefore will yield forty and the second twenty bushels of extra profit, constituting the rent of the landlord. And first, let an improvement be made, which, without enabling more corn to be grown, enables the same corn to be grown with one-fourth less labour. The price of wheat will fall one-fourth, and 80 bushels will be sold for the price for which 60 were sold before. But the produce of the land which produces 60 bushels is still required, and the expenses being as much reduced as the price, that land can still be cultivated with the ordinary profit. The first and second qualities will therefore continue to yield a surplus of 40 and 20 bushels, and corn rent will remain the same as before. But corn having fallen in price one-fourth, the same corn rent is equivalent to a fourth less of money and of all other commodities. So far, therefore, as the landlord expends his income in manufactured or foreign products, he is one-fourth worse off than before. His income as landlord is reduced to three-quarters of its amount: it is only as a consumer of corn that he is as well off.
