lation suffices to make up for—it does not follow that the aggregate production, as compared with the aggregate labor, has been lessened.
Let us suppose land of diminishing qualities. The best would naturally be settled first, and as population increased production would take in the next lower quality, and so on. But, as the increase of population, by permitting greater economies, adds to the effectiveness of labor, the cause which brought each quality of land successively into cultivation would at the same time increase the amount of wealth that the same quality of labor could produce from it. But it would also do more than this—it would increase the power of producing wealth on all the superior lands already in cultivation. If the relations of quantity and quality were such that increasing population added to the effectiveness of labor faster than it compelled a resort to less productive qualities of land, though the margin of cultivation would fall and rent would rise, the minimum return to labor would increase. That is to say, though wages as a proportion would fall, wages as a quantity would rise. The average production of wealth would increase. If the relations were such that the increasing effectiveness of labor just compensated for the diminishing productiveness of the land as it was called into use, the effect of increasing population would be to increase rent by lowering the margin of cultivation without reducing wages as a quantity, and to increase the average production. If we now suppose population still increasing, but, between the poorest quality of land in use and the next lower quality, to be a difference so great that the increased power of labor which comes with the increased population that brings it into cultivation cannot compensate for it—the minimum return to labor will be reduced, and with the rise of rents, wages will fall, not only as a proportion, but as a quantity. But unless the descent in
