With an adroitness which does credit to the characteristic charlatanism of the North, an infinite variety of special questions and side issues have been interwoven with the narrative of the late war, for the obvious purpose of confounding the judgment of mankind regarding the great question which really constitutes the gravamen of the controversy. Conspicuous among these efforts, from both audacity and plausibility, are appeals to the sympathies of the world, in consideration of the abolition of slavery, which it is well known was merely an incident, and not the avowed design of the war. Persistent in its introduction of the _moral_ question of slavery, the North seeks to shield itself from the reproach justly visited upon its perpetration of an atrocious political crime, by an insolent intrusion of a false claim to the championship of humanity. Whatever may be the decision of Time upon the merits of slavery, it is in vain for the North to seek escape from its responsibility for an institution, protected and sustained by a government which was the joint creation of Southern and Northern hands. The attempted dissolution of the Union by the South was a movement involving moral and political considerations, not unlike those incidental to revolutions in general, yet presenting certain peculiar characteristics, traceable to the inherent and distinctive features of the American political system. These latter considerations constitute a vital part of its justification. The South did not appeal only to the inalienable right of revolution, which is the natural guarantee of resistance to wrong and oppression. Nor did the States, severally, as they assumed to sever their connection with the Union, announce a purpose of constitutional revolution, or adopt a course inviting or justifying violence. Mr. Davis and those who coöperated with him, neither by the acts of secession, nor the subsequent confederation of the States under a new government, could have committed _treason_ against Mr. Lincoln, since they were not his subjects. Nor yet were they traitors to the Government of the United States, since the States of which they were citizens had rescinded the grant of powers voluntarily made by them to that Government, and begun to exercise them in conjunction with other powers which they had withheld by express reservation.
