Industry, economy, temperance, self-culture, education for their children,--these things, indispensable to their elevation and progress, are in a great measure in their own hands. You will, therefore, my friends and fellow-citizens, pardon me if I decline to undertake to decide for you the question of your political duty as respects the candidates for the presidency,--a question which you have probably already settled in your own minds. If it had been apparent to me that your rights and liberties were really in danger from the success of either candidate, your letter would not have been needed to call forth my opinion. In the long struggle of well-nigh forty years, I can honestly say that no consideration of private interest, nor my natural love of peace and retirement and the good-will of others, have kept me silent when a word could be fitly spoken for human rights. I have not so long acted with the class to which you belong without acquiring respect for your intelligence and capacity for judging wisely for yourselves. I shall abide your decision with confidence, and cheerfully acquiesce in it. If, on the whole, you prefer to vote for the reelection of General Grant, let me hope you will do so without joining with eleventh-hour friends in denouncing and reviling such an old and tried friend as Charles Sumner, who has done and suffered so much in your behalf. If, on the other hand, some of you decide to vote for Horace Greeley, you need not in so doing forget your great obligations to such friends as William Lloyd Garrison, Wendell Phillips, and Lydia Maria Child. Agree or disagree with them, take their advice or reject it, but stand by them still, and teach the parties with which you are connected to respect your feelings towards your benefactors. THE CENSURE OF SUMNER. A letter to the Boston Daily Advertiser in reference to the petition for the rescinding of the resolutions censuring Senator Sumner for his motion to erase from the United States flags the record of the battles of the civil war. I BEG leave to occupy a small space in the columns of the Advertiser for the purpose of noticing a charge which has been brought against the petitioners for rescinding the resolutions of the late extra session virtually censuring the Hon. Charles Sumner. It is intimated that the action of these petitioners evinces a lack of appreciation of the services of the soldiers of the Union, and that not to censure Charles Sumner is to censure the volunteers of Massachusetts.
