PROGRESS OF WEALTH.--By Census Tables (1860) 33 and 36, it appears (omitting commerce) that the products of industry, as given, viz., of agriculture, manufactures, mines, and fisheries, were that year in Pennsylvania, of the value of $398,600,000, or $137 per capita; and in Virginia, $120,000,000 or $75 per capita. This shows a total value of product in Pennsylvania much more than three times that of Virginia, and, per capita, nearly two to one. That is, the average value of the product of the labor of each person in Pennsylvania, is nearly double that of each person, including slaves, in Virginia. Thus is proved the vast superiority of free over slave labor, and the immense national loss occasioned by the substitution of the latter for the former. As to the rate of increase; the value of the products of Virginia in 1850 was $84,480,428 (Table 9), and in Pennsylvania, $229,567,131, showing an increase in Virginia, from 1850 to 1860, of $35,519,572, being 41 per cent.; and in Pennsylvania, $169,032,869, being 50 per cent.; exhibiting a difference of 9 per cent. in favor of Pennsylvania. By the Census Table of 1860, No. 35, p. 195, the true value then of the real and personal property was, in Pennsylvania, $1,416,501,818, and of Virginia, $793,249,681. Now, we have seen, the value of the products in Pennsylvania in 1860 was $398,600,000, and in Virginia, $120,000,000. Thus, as a question of the annual yield of capital, that of Pennsylvania was 28.13 per cent., and of Virginia, 15.13 per cent. By Census Table 35, the total value of the real and personal property of Pennsylvania was $722,486,120 in 1850, and $1,416,501,818 in 1860, showing an increase, in that decade, of $694,015,698, being 96.05 per cent.; and in Virginia, $430,701,082 in 1850, and $793,249,681 in 1860, showing an increase of $362,548,599, or 84.17 per cent.
