From 1790 to 1800 38.67 per cent. " 1800 " 1810 34.49 " " 1810 " 1820 29.55 " " 1820 " 1830 28.47 " " 1830 " 1840 27.87 " " 1840 " 1850 34.09 " " 1850 " 1860 25.71 " In 1790 the population of Virginia was 748,318; in 1820, 1,065,129, and in 1860, 1,596,318. In 1790 the population of Pennsylvania was 434,373; in 1820, 1,348,233, and in 1860, 2,906,115. Thus, from 1790 to 1820, before the inauguration of the protective policy, the relative increase of the population of Pennsylvania, as compared with Virginia, was very far greater than from 1820 to 1860. It is quite clear, then, that the tariff had no influence in depressing the progress of Virginia as compared with Pennsylvania. Having shown how much the material progress of Virginia has been retarded by slavery, let us now consider its effect upon her moral and intellectual development. NEWSPAPERS AND PERIODICALS.--The number of newspapers and periodicals in Pennsylvania in 1860 was 367, of which 277 were political, 43 religious, 25 literary, 22 miscellaneous; and the total number of copies circulated in 1860 was 116,094,480. (Census Tables, Nos. 15, 37.) The number in Virginia was 139, of which 117 were political, 13 religious, 3 literary, 6 miscellaneous; and the number of copies circulated in 1860 was 26,772,568, being much less than one fourth that of Pennsylvania. The number of copies of monthly periodicals circulated in Pennsylvania in 1860 was 464,684; and in Virginia, 43,900; or much more than ten to one in favor of Pennsylvania. As regards schools, colleges, academies, libraries, and churches, I must take the Census of 1850, those tables for 1860 not being yet arranged or printed. The number of public schools in Pennsylvania in 1850 was 9,061; teachers, 10,024; pupils, 413,706; colleges, academies, &c., pupils, 26,142; attending school during the year, as returned by families, 504,610; native adults of the State who cannot read or write, 51,283; public libraries, 393; volumes, 363,400; value of churches, $11,853,291; percentage of native free, population (adults) who cannot read or write, 4.56.
