shows the steady expansion of the contributions of the government. In this census the government not only sought all that had been sought in the previous census, but made finer subdivisions as to ages and as to foreigners not naturalized.
The contributions to social science under the enumeration of 1830 were practically repetitions of those under previous censuses, the chief elaboration being a still finer subdivision of ages, specifying by sex, and whether slaves, free colored persons, or free white persons.

All the features of previous schedules were retained, not only as to ages—a better classification being incorporated—but as to the deaf and dumb. Beyond these features comprehended in the enumeration of 1830, that of 1840 ascertained the number of persons employed in mining, agriculture, commerce, manufactures and trade, navigation of the ocean, navigation of canals, lakes and rivers, and in learned professions and engineering. Here was a departure in exact conformity in this respect to the appeals of the memorialists of 1800, and in further compliance with the terms or principles of such appeals Congress called for the number of universities and colleges, the number of students therein, the number of academies and grammar schools and their pupils, the number of primary and common schools, and the whole number of scholars at public charge; but going still deeper into the character of the population. Congress asked the number of white persons over 20 years of age who could not
