Present condition of Slavery--Not an isolated system--Its relations to other industrial interests--To manufactures, commerce, trade, human comfort--Its benevolent aspect--The reverse picture--Immense value of tropical possessions to Great Britain--England's attempted monopoly of Manufactures--Her dependence on American Planters--Cotton Planters attempt to monopolize Cotton markets--_Fusion_ of these parties--Free Trade essential to their success--Influence on agriculture, mechanics--Exports of Cotton, Tobacco, etc.--Increased production of Provisions--Their extent--New markets needed. THE institution of slavery, at this moment, gives indications of a vitality that was never anticipated by its friends or foes. Its enemies often supposed it about ready to expire, from the wounds they had inflicted, when in truth it had taken two steps in advance, while they had taken twice the number in an opposite direction. In each successive conflict, its assailants have been weakened, while its dominion has been extended. This has arisen from causes too generally overlooked. Slavery is not an isolated system, but is so mingled with the business of the world, that it derives facilities from the most innocent transactions. Capital and labor, in Europe and America, are largely employed in the manufacture of cotton. These goods, to a great extent, may be seen freighting every vessel, from Christian nations, that traverses the seas of the globe; and filling the warehouses and shelves of the merchants over two-thirds of the world. By the industry, skill, and enterprise employed in the manufacture of cotton, mankind are better clothed; their comfort better promoted; general industry more highly stimulated; commerce more widely extended; and civilization more rapidly advanced than in any preceding age. To the superficial observer, all the agencies, based upon the sale and manufacture of cotton, seem to be legitimately engaged in promoting human happiness; and he, doubtless, feels like invoking Heaven's choicest blessings upon them. When he sees the stockholders in the cotton corporations receiving their dividends, the operatives their wages, the merchants their profits, and civilized people everywhere clothed comfortably in cottons, he can not refrain from exclaiming: The lines have fallen unto them in pleasant places; yea, they have a goodly heritage!
