They are the precursors in the great army of destruction; and often finish the dreadful work themselves.

But should they fail in this war of extermination, sickly seasons, epidemics, pestilence, and plague, advance in terrific array, and sweep off their thousands and ten thousands.

Should success be still incomplete, gigantic inevitable famine stalks in the rear, and with one mighty blow levels the population with the food of the world.
Must it not then be acknowledged by an attentive examiner of the histories of mankind, that in every age and in every state in which man has existed, or does now exist.
That the increase of population is necessarily limited by the means of subsistence.
That population does invariably increase when the means of subsistence increase.

And that the superior power of population it repressed, and the actual population kept equal to the means of subsistence, by misery and vice?
