The African slave trade to America commenced three centuries and a half since. By the time of the American Revolution, the supply of slaves had exceeded the demand for slave labor, and the slaveholders, to get rid of a burden, and to prevent the increase of a nuisance, became violent opponents of the slave trade, and many of them abolitionists. New England, Bristol, and Liverpool, who reaped the profits of the trade, without suffering from the nuisance, stood out for a long time against its abolition. Finally, laws and treaties were made, and fleets fitted out to abolish it; and after a while, the slaves of most of South America, of the West Indies, and of Mexico were liberated. In the meantime, cotton, rice, sugar, coffee, tobacco, and other products of slave labor, came into universal use as necessaries of life. The population of Western Europe, sustained and stimulated by those products, was trebled, and that of the North increased tenfold. The products of slave labor became scarce and dear, and famines frequent. Now, it is obvious, that to emancipate all the negroes would be to starve Western Europe and our North. Not to extend and increase negro slavery, _pari passu_, with the extension and multiplication of free society, will produce much suffering. If all South America, Mexico, the West Indies, and our Union south of Mason and Dixon's line, of the Ohio and Missouri, were slaveholding, slave products would be abundant and cheap in free society; and their market for their merchandise, manufactures, commerce, &c., illimitable. Free white laborers might live in comfort and luxury on light work, but for the exacting and greedy landlords, bosses and other capitalists. We must confess, that overstock the world as you will with comforts and with luxuries, we do not see how to make capital relax its monopoly--how to do aught but tantalize the hireling. Capital, irresponsible capital, begets, and ever will beget, the "immedicabile vulnus" of so-called Free Society. It invades every recess of domestic life, infects its food, its clothing, its drink, its very atmosphere, and pursues the hireling, from the hovel to the poor-house, the prison and the grave. Do what he will, go where he will, capital pursues and persecutes him. "Hæret lateri lethalis arundo!" Capital supports and protects the domestic slave; taxes, oppresses and persecutes the free laborer. CHAPTER XXII. THE STRENGTH OF WEAKNESS. An unexplored moral world stretches out before us, and invites our investigation; but neither our time, our abilities, nor the character of our work, will permit us to do more than glance at its loveliness.
