It has become a well-established fact that agricultural and mineral production underwent marked increase during the eighteenth century in Latin America. An expanding European market, regular and abundant maritime transportation, the lowering of taxes, the reduction of prices of crown monopolies, and the granting of government loans to industry were all factors which, in varying degree, stimulated increased production. Less well known, however, is the fact that in some areas production failed to rise above an unimpressive level despite these favorable conditions and official encouragement. The Central American mining industry, for example, experienced no noticeable change in productivity during the last half of the eighteenth century, although trade increased in volume, stimulative legislation was implemented, and penetrating suggestions—reflecting rays of the Enlightenment— were offered by miners and government officials.
