Grateful for the kindness of friends who have thought me worthy of political confidence, and regretting much that it is not bestowed upon some one else, who would fitly represent the idea of opposition to the longer continuance of the unjust war with Mexico, I beg leave respectfully, but explicitly, to withdraw my name from the canvass. CHARLES SUMNER. SATURDAY, OCTOBER 31. SLAVERY AND THE MEXICAN WAR. SPEECH AT A PUBLIC MEETING IN THE TREMONT TEMPLE, BOSTON, NOVEMBER 5, 1846. The sentiment against Slavery and the Mexican War found expression in the independent nomination of Dr. S.G. Howe as Representative to Congress. At a meeting of citizens to support this nomination, John A. Andrew, Esq., was called to the chair. The following resolution was reported from the District Committee by John S. Eldridge, Esq. * * * * * "_Resolved_, That in the determination of our candidate, Dr. SAMUEL G. HOWE, 'to stand and be shot at,' we recognize the spirit of a man distinguished by a life of service in various fields of humanity; and, confidently trusting in the triumph of sound principles, we heartily pledge ourselves to make, with untiring zeal, every honorable effort to secure the election of a candidate who has boldly identified himself with the cause of Truth, Peace, Justice, the Liberties of the North, and the Rights of Man." * * * * * On this resolution Mr. Sumner made the speech given below. He was followed by Hon. C.F. Adams, who reviewed the Anti-Slavery policy pursued for several years by the Massachusetts Legislature, and the obstacles they encountered. At the election, which took place on Monday, November 9th, the vote was as follows: Winthrop (Whig), 5,980; Howe (Anti-Slavery), 1,334; Homer (Democrat), 1,688; Whiton (Independent), 331.
