Until slavery and slaveholders cease to be the only favored objects of legislation in the South, the North will continue to maintain the ascendency in every important particular. With those loathsome objects out of the way, it would not take the non-slaveholders of the South more than a quarter of a century to bring her up, in all respects, to a glorious equality with the North; nor would it take them much longer to surpass the latter, which is the most vigorous and honorable rival that they have in the world. Three quarters of a century hence, if slavery is abolished within the next ten years, as it ought to be, the South will, we believe, be as much greater than the North, as the North is now greater than the South. Three quarters of a century hence, if the South retains slavery, which God forbid! she will be to the North much the same that Poland is to Russia, that Cuba is to Spain, or that Ireland is to England. What we want and must have, as the only sure means of attaining to a position worthy of Sovereign States in this eminently progressive and utilitarian age, is an energetic, intelligent, enterprising, virtuous, and unshackled population; an untrammeled press, and the Freedom of Speech. For ourselves, as white people, and for the negroes and other persons of whatever color or condition, we demand all the rights, interests and prerogatives, that are guarantied to corresponding classes of mankind in the North, in England, in France, in Germany, or in any other civilized and enlightened country. Any proposition that may be offered conceding less than this demand, will be promptly and disdainfully rejected. Speaking of the non-slaveholders of the South, George M. Weston, a zealous co-laborer in the cause of Freedom, says:--
