Mr. Cushing affects to see in the history of the Slavery Agitation nothing but a series of injuries inflicted by the North on the South. He charges "some of the Northern States" with acts of aggression upon the South "which would have been just cause of war as between foreign governments." He prudently forbears to name any. Does he mean, that persons have been found in some of those States unnational enough, un-Original-Democratic enough, to give a cup of water to a hunted Christian woman, or to harbor an outcast Christian man, without first submitting their hair to a microscopic examination? Does he mean, that we have said hard things of our Southern brethren? Grose's "Classical Dictionary of the Vulgar Tongue" is open to them as well as to us, and the Richmond "South" is surely not in the habit of sprinkling the Northern subjects of its animadversion with rose-water. No,--what Mr. Cushing means is this,--that there are men at the North who will not surrender the principles they have inherited from three revolutions because they are threatened with a fourth that will never come,--who do not consider it an adequate success in our experiment of self-government that we can produce such types of nationality as reckon the value of their country by the amount of salary she pays,--who will not believe that there is no higher kind of patriotism than complicity in every violent measure of an administration which redeems only its pledges to a faction of Southern disunionists,--who will not admit that slave-holding is the only important branch of national industry, because the profession of that dogma enables unscrupulous men to enter the public service poor and to leave it rich. Has any citizen of a Southern State ever failed to obtain justice (that is to say, in the language of Original Democracy, his _nigger_) in a Northern court? Has Massachusetts ever mobbed an envoy or brutally assaulted a Senator of South Carolina? Has any Northern State ever nullified an article of the Federal Constitution, as every seaboard Slave-State has always done in respect to the colored citizens of the North? When a man's allowing himself to be kicked comes to be reckoned an outrage on the kicker, then Mr. Cushing's notion of what constitutes a "just cause of war" will deserve as much consideration as Mr. G.T. Curtis's theory that hustling a deputy-marshal is "levying" it. We can remember when the confirmation of an ambassador to England (where the eminent fitness of the nomination was universally conceded) was opposed by several Southern Senators on the ground that he had expressed an interest in the success of West India emancipation. If Original Democrats have their way, it will not be long before it is made constructive treason to have read that chapter of the Acts of the Apostles which relates the misguided philanthropy of Philip in endeavoring to convert an Ethiopian into anything but a chattel.
