The times are bravely altered. The partnership between Slavery and Unionism is absolutely dissolved. Like most divorces, this involves a deadly quarrel. Not even the soaring platitudes of George Francis Train can longer evoke cheers for the Union blent with curses on Abolition. In a strictly, sternly real sense, "Liberty and Union" are henceforth "one and inseparable!" For thirty years, our great seaboard merchants, our shippers, our factors, have given their patronage to pro-slavery journals and their votes to pro-slavery politicians, with intent to preserve the Union and lay the red spectre of civil war. Their recompense is found in the repudiation of the immense debts for merchandise due them from the South, and a gigantic war waged by the Slave Power for the overthrow of the Union. The profits of a lifetime of obsequious pandering to the master crime of our era are swept away at a blow, and the arm that strikes it is that of the monster they have made such sacrifices of conscience and manhood to conciliate. Was ever retribution more signal? To-day, the American Union, through the official action of its President and Congress, stands distinctly on the side of Liberty for All. Its success in the fearful struggle forced upon it involves the overthrow and extinction of American slavery. The sentiment of nationality, the instinct which impels every people to deprecate and resist the dismemberment and degradation of their country, the impulse of loyalty, are all arrayed against the traitorous "institution" which, after having so long bent the Union to its ends, now seeks its destruction. It once seemed to the majority patriotic to champion slavery; it is now a sacred duty to resist the bloody Moloch unto death. The very hesitation of the President to take the decisive step gives weight to his ultimate decision. The compromisers have never tired of eulogizing his firmness, his candor, his patience, his clearness of vision, his independence, and his unsectional patriotism. His associations were largely with the Border State school of conservatives. His favorite counsellor was the most eminent and sturdy Republican opponent of an emancipation policy. His decision in favor of that policy, like the Proclamation which announces it, is entirely his own. The "pressure" to which he deferred was that of an urgent public necessity and the emphatic conviction of the great mass of our loyal citizens. And, though few days have elapsed since the Proclamation was uttered, the evils predicted by its opponents are already banished to the limbo of chimera. Those officers who threatened to resign in case an emancipation policy were adopted make no haste to justify their menaces. As yet, not one of them has done so; in time, a few may screw their courage to the sticking-point. There are enough who can be spared; and they are generally those who deprecate and denounce an "Abolition war." May they yet prove men of their word!
