Before leaving this picture, where the dismal colors all come from official sources, there are two other aspects in which Slavery may be regarded. 1. The first is its influence on emigration. The official compendium of the census (page 115) tells us that inhabitants of Slave States who are natives of Free States are more numerous than inhabitants  of Free States who are natives of Slave States. This is an egregious error. Just the contrary is true. The census of 1850 found 606,139 in the Free States who were born in the Slave States, while only 206,624 born in the Free States were in the Slave States. And since the white population of the Free States is double that of the Slave States, it appears that the proportion of whites moving from Slavery is six times greater than that of whites moving into Slavery. This simple fact discloses something of the aversion to Slavery which is aroused even in the Slave States. 2. The second is furnished by the character of the region on the border-line between Freedom and Slavery. In general, the value of land in Slave States adjoining Freedom is advanced, while the value of corresponding lands in Free States is diminished. The effects of Freedom and Slavery are reciprocal. Slavery is a bad neighbor; Freedom is a good neighbor. In Virginia, lands naturally poor are, by nearness to Freedom, worth $12.98 an acre, while richer lands in other parts of the State are worth only $8.42. In Illinois, lands bordering on Slavery are worth only $4.54 an acre, while other lands in Illinois are worth $8.05. As in the value of lands, so in all other influences is Slavery felt for evil, and Freedom felt for good; and thus is it clearly shown to be for the interest of the Slave States to be surrounded by a circle of Free States. At every point is the character of Slavery more and more manifest, rising and dilating into an overshadowing Barbarism, darkening the whole land. Through its influence, population, values of all kinds, manufactures, commerce, railroads, canals, charities, the post-office, colleges, professional schools, academies, public schools, newspapers, periodicals, books, authorship, inventions, are all stunted, and, under a Government which professes to be founded on the intelligence of the people, one in five of native white adults in the region of Slavery is officially reported as unable to read and write. Never was the saying of Montesquieu more triumphantly verified, that countries are not cultivated by reason of their fertility, but by reason of their liberty. To this truth the Slave States testify perpetually by every possible voice. Liberty is the powerful agent which drives the plough, the spindle, and the keel,—opens avenues of all kinds,—inspires charity,—awakens love of knowledge, and supplies the means of gratifying it. Liberty is the first of schoolmasters: nay, more; it is the Baconian philosophy of Civilization, through which the powers and activities of man are enlarged beyond measure or imagination.
