 the quality of land is far more precipitous than we can well imagine, or than, I think, ever exists, the average production will still be increased, for the increased effectiveness which comes by reason of the increased population that compels resort to the inferior quality of land attaches to all labor, and the gain on the superior qualities of land will more than compensate for the diminished production on the quality last brought in. The aggregate wealth production, as compared with the aggregate expenditure of labor, will be greater, though its distribution will be more unequal.

Thus, increase of population, as it operates to extend production to lower natural levels, operates to increase rent and reduce wages as a proportion, and may or may not reduce wages as a quantity; while it seldom can, and probably never does, reduce the aggregate production of wealth as compared with the aggregate expenditure of labor, but on the contrary increases, and frequently largely increases it.

But while the increase of population thus increases rent by lowering the margin of cultivation, it is a mistake to look upon this as the only mode by which rent advances as population grows. Increasing population increases rent, without reducing the margin of cultivation; and notwithstanding the dicta of such writers as McCulloch, who assert that rent would not arise were there an unbounded extent of equally good land, increases it without reference to the natural qualities of land, for the increased powers of co-operation and exchange which come with increased population are equivalent to—nay, I think we can say without metaphor, that they give—an increased capacity to land.

I do not mean to say merely that, like an improvement in the methods or tools of production, the increased power which comes with increased population gives to the same labor an increased result, which is equivalent
