To illustrate this effect of labor-saving machinery and improvements, let us suppose a country where, as in all the countries of the civilized world, the land is in the possession of but a portion of the people. Let us suppose a permanent barrier fixed to further increase of population, either by the enactment and strict enforcement of an Herodian law, or from such a change in manners and morals as might result from an extensive circulation of Annie Besant's pamphlets.
