A LATE number of Fraser's Magazine contains an article bearing the unmistakable impress of the Anglo-German peculiarities of Thomas Carlyle, entitled, 'An Occasional Discourse on the Negro Question', which would be interesting as a literary curiosity were it not in spirit and tendency so unspeakably wicked as to excite in every rightminded reader a feeling of amazement and disgust. With a hard, brutal audacity, a blasphemous irreverence, and a sneering mockery which would do honor to the devil of Faust, it takes issue with the moral sense of mankind and the precepts of Christianity. Having ascertained that the exports of sugar and spices from the West Indies have diminished since emancipation,--and that the negroes, having worked, as they believed, quite long enough without wages, now refuse to work for the planters without higher pay than the latter, with the thriftless and evil habits of slavery still clinging to them, can afford to give,--the author considers himself justified in denouncing negro emancipation as one of the "shams" which he was specially sent into this world to belabor. Had he confned himself to simple abuse and caricature of the self-denying and Christian abolitionists of England--"the broad-brimmed philanthropists of Exeter Hall"--there would have been small occasion for noticing his splenetic and discreditable production. Doubtless there is a cant of philanthropy --the alloy of human frailty and folly--in the most righteous reforms, which is a fair subject for the indignant sarcasm of a professed hater of shows and falsities. Whatever is hollow and hypocritical in politics, morals, or religion, comes very properly within the scope of his mockery, and we bid him Godspeed in plying his satirical lash upon it. Impostures and frauds of all kinds deserve nothing better than detection and exposure. Let him blow them up to his heart's content, as Daniel did the image of Bell and the Dragon. But our author, in this matter of negro slavery, has undertaken to apply his explosive pitch and rosin, not to the affectation of humanity, but to humanity itself. He mocks at pity, scoffs at all who seek to lessen the amount of pain and suffering, sneers at and denies the most sacred rights, and mercilessly consigns an entire class of the children of his Heavenly Father to the doom of compulsory servitude. He vituperates the poor black man with a coarse brutality which would do credit to a Mississippi slave-driver, or a renegade Yankee dealer in human cattle on the banks of the Potomac. His rhetoric has a flavor of the slave-pen and auction-block, vulgar, unmanly, indecent, a scandalous outrage upon good taste and refined feeling, which at once degrades the author and insults his readers.
