The support given lo slavery by the the legislation of the free states; the corruption and perversiÃ³n of our general government by the slaveholding power ; the disturbante ihis hasproduced and sliil pro duees in the policy of the country; its injurious influence over the politics of the free states - are all subjects of great political itnportance. They are polilical evÃ¼s, and can be remedied in no other way than by political aclion. Dr. Channing insista upon the duty of freeing ourselvos from all obligation to sustain slavery under any form. Wc must suppress slavery in the District of Columbia, and the domestic slave trade; we musÃ seek an amendmentofthe constitution so as to relieve ourselves from the engagement to surrenderup fngitive slaves; we must not suffer the power of the federal government to be abused for the support of slavery. Thnse in his view, are duties of the cilizens of the free states. But, they are polilical duties, and can only be fulÃ±lled through political instrumentalities. This being granted, it is in vain to talk to us of the danger of losing our reputation for philanthropy, and incurring the od iumL of place andjpower seekers. I have yet to learn that it is a disgrace to seek power, solong as no correct principie is viol.ited. I cannotfunderstand why YVm. H. [Harrison or Martin Van Buren may aspire to office, and that too at the expense of their integrity, with out being censured for their conduct; while James G. Birney must be denouneed as dishonest for accepting a nomination, and at the same time rnaintaining his integrity and boldly avowing the genuine principies of republicanism. The man,who bows his neck, and receiyes the mark of the beast in his ibrehead as a passport to office, shall go unquestioned - he is an honorable man. The aboli - tionist, who stands stifF in his principies, and while asking the tuffrages of his fel- low citizensjpoinls to hishalred of slavery is the ground of his claims, is insincere, hypocritical, a mere self seckini man!But, allow that it is disgraceful to be an aspirunt fJr office, even on right principies and that political abolitionists wilt reuder themselves liable to this grave imputation, it is nothing to us. We vvere not sent into the world to nurse our reputaiions, but to act out right principies. A good name is a good thing, but it may be bought at too dear a rate. He who is forever shrinking from decisive measure?, lest his motives should be disparaged, is not tho man to make the crooked things straight in a perverse world. There is times when it bccomesa high duty to sacrifice reputaiion, to place one's self in even suspicious circumstances, forthe sake of accomplishing a greatgood - and the only consolation is, that He, to whom the night is as day, wili not misunderstand us. All apprehensious then, of a blot on our good names, we give to the winds.
