The analysis of developed motives in which the slaveholders' rebellion had its origin, must naturally excite the inquiry in the American mind, as to how far the slaveholding element can be trusted. As a political force, we find it sowing the seeds of political discontent. As an anti-democratic element, we find it plotting the overthrow of democratic government. In its efforts to denationalize republican government in America, it has not scrupled to seek aid from, and alliance with, the haters of republican institutions every where. Under such calamitous teachings as it has inflicted, can we longer conclude that it can, from its aptitudes and nature, be converted into an element of national strength? There is a South, and a great South, and would continue to be, were there not a negro or slaveholder sojourning there. The seven millions non-slaveholding population in the Southern States have rights, social and political, based on the motive to maintain republican government. The Constitution of the Union, as the highest principle of fundamental law, guarantees in express terms, to every State, the form of a republican government; and not less by implication, the essential qualities of an actual one. It matters not how much the non-slaveholding population of the South may have been deluded, nor how much it may have been incited, under that delusion, to act as the instrument of its own overthrow. This population is not less the object of just political solicitude than any equal number of people North. That its general education has not been advanced to the appreciative point, is its misfortune. That it has been surrounded by a pro-slavery influence, selfish, arrogant, and contemptuous of the interest of the masses, is equally so. That it has been less favored than its brother-hood of free labor in the North--that it has been placed under disabilities in the comparison, are only additional reasons for increased solicitude for the welfare and future advancement of this portion of Southern population. While it has been imposed upon, and much of it deluded in its motives to action, its actual condition is in reality coupled with every natural incentive to alliance and adhesion to the National Government. It has drunk the bitter cup of calamity in rebellion. It has tasted the dregs of treason that lie at the bottom of political vice, and been victimized by destitution, by the diseases of camp-life, by the casualties of the battle-field, and by the widowhood and orphanage that have followed the train of rebellion. This population is a natural element of national strength, having the same incentives as its brotherhood in the North. Arms will soon remove the blockade to its intercourse with the North, and civil liberty once established, will most likely secure it to the side of national patriotism.
