Note 56 — Chapter III · OF THE EFFECT UPON INDIVIDUALS AND CLASSES.

Besides the enormous increase in the productive power of labor which would result from the better distribution of population, there would be also a similar economy in the productive power of land. The concentration of population in cities fed by the exhaustive cultivation of large, sparsely populated areas, results in a literal draining into the sea of the elements of fertility. How enormous this waste is may be seen from the calculations that have been made as to the sewage of our cities, and its practical result is to be seen in the diminishing productiveness of agriculture in large sections. In a great part of the United States we are steadily exhausting our lands.
