in 1860, 672,035, being an increase of 264 per cent. (264.96) for New Jersey, of 225 per cent. (225.06) for Massachusetts, and for Maryland 114 percent. (114.88). The ratio of increase per square mile from 1790 to 1860 was: Massachusetts, 48.55 in 1790, and 157.82 in 1860; Maryland, 28.74 in 1790, and 61.76 in 1860; and New Jersey, 22.01 in 1790, and 80.70 in 1860. Thus, while Maryland from 1790 to 1860, little more than doubled her ratio of increase per square mile (28.74 to 61.76), and Massachusetts little more than tripled her ratio (48.55 to 157.82), New Jersey very nearly quadrupled hers (22.01 to 80.70). It must be conceded, however, that the natural advantages of New Jersey are far greater than those of Massachusetts, whose material and intellectual progress, in defiance of such serious obstacles, now is, and most probably forever will be, without a parallel. Now the area of New Jersey is but 8,320 square miles; the soil of Maryland is far more fertile, the hydraulic power much greater, the shoreline much more than double, viz.: 531 for New Jersey, to 1,336 for Maryland; while New Jersey, with rich iron mines, has no coal, and one third of her area is south of the celebrated Mason and Dixon's line, the northern boundary of Maryland. While the Free States have accomplished these miracles of progress, they have peopled eleven vast Territories (soon by subdivision to become many more States), immigration to which has been almost exclusively from the North as compared with the South.
The Slave State which has increased most rapidly to the square mile of all of them from 1790 to 1860, has had a smaller augmentation per square mile than that Free State which has increased most slowly per square mile during the same time of all the Free States, and the result is the same as to wealth and education also. Under the best circumstances for the Slave States, and the worst for the Free States, this result proves the uniformity of the rule (like the great law of gravitation), knowing no exception to the effect of slavery in depressing the progress of States in population, wealth, and education.
The isothermals of the great Humboldt (differing so widely from parallels), which trace the lines of temperature on the earth's surface, prove, as to heat, the climate of the South (running a line from Charleston to Vicksburg) to be substantially the same as that of Greece and Italy-each, in its turn, the mistress of the world.
The Census of 1860 exhibits our increase of population from 1790 to 1860 at 35.59 per cent., and of our wealth 126.45. Now, if we would increase the wealth of the country only one tenth in the next ten years, by the gradual disappearance of slavery (far below the results of the Census), then our wealth being now $16,159,616,068, the effect of such increase would be to make our wealth in 1870, instead of $36,593,450,585, more than sixteen hundred millions greater, and in 1880, instead of $82,865,868,849, over three billions six hundred millions, or more than three times our present debt.
Before the close of this letter, it will be shown that the difference, per capita, of the annual products of Massachusetts and Maryland exceeds $150. As to the other Southern States, the excess is much greater. Now, if the annual products of the South were increased $150 each per capita (still far below Massachusetts) by the exclusion of slavery, then multiplying the total population of the South, 12,229,727, by 150, the result would be an addition to the annual value of the products of the South of $1,834,456,050, and in the decade, $18,344,580,500. This change would not be immediate, but there can be no doubt that with the vastly greater natural advantages of the South, the superiority of free to slave labor, the immense immigration, especially from Europe to the South, aided by the Homestead Bill, and the conversion of large plantations into small farms, an addition of at least one billion of dollars would be made in a decade, by the exclusion of slavery, to the value of the products of the South.
Having considered the relative progress in population of Massachusetts and Maryland, I will now examine their advance in wealth.
By Tables 33 and 36, Census of 1860, the value of the products of Massachusetts that year was $287,000,000; and of Maryland, $66,000,000. Table 33 included domestic manufactories, mines, and fisheries (p. 59); and Table 36, agricultural products. Dividing these several aggregates by the total population of each State, the value of that year's product of Massachusetts was $235 per capita, and of Maryland, $96, making the average annual value of the labor of each person in the former greatly more than double that of the latter, and the gross product more
