Of these, Hon. Amasa Walker, afterwards a Representative in Congress from Massachusetts, wrote:-- "Your reply to the slaveholders is capital, and receives universal admiration in this quarter. It was just such a flagellation as the slavocrats deserved, and such a one as they never received before in the Senate. I think, from what I can observe, that your course is universally popular, always excepting the mercenary minions of the Government." J. P. Blanchard, Esq., devoted to Peace, wrote:-- "I take this occasion to express my warm admiration of the spirit and power you have exhibited in your late contest with Messrs. Butler, Pettit, _et id genus omne_. I am rejoiced and grateful that your 'backbone' has proved strong enough to stand such a test without bending: that I have not given you this acknowledgment earlier is because, being very busy, I did not take time to write a letter for that purpose only, as I knew you were so well acquainted with my sympathies that the expression of them was unnecessary. I am glad to understand that you have received commendations on this score from sources where a short time ago you would not have expected them." Elihu Burritt, the Missionary of Peace, wrote:-- "And now I want to thank you with my whole heart for your grand and brave rejoinder to Butler and Mason. It was the best, bravest thing done in the Senate this many a year. I think more hearts in the Free States will glory in your courageous and overwhelming reply to these plantation Senators than in any public effort of your life. You must have made it, too, on short notice. I never read anything with more satisfaction." Other letters attest a change in sentiment among those who had been lukewarm on Slavery, and perhaps adverse to Mr. Sumner. Hon. Daniel Shattuck, of Concord, wrote:-- "Being one of the old-time Whigs, I was not pleased with your election to the high seat which you hold: for that opinion you will forgive me, I am sure, when I say that I go with you now heart and soul, and approve all you have said in defence of your native State, whose sons I know approve your course and wish you God-speed. George M. Browne, Esq., of Boston, wrote:-- "Differing with you as I do in political sentiments, and having no other connection with public affairs than what pertains to every citizen, I desire nevertheless to express to you, what I believe to be the general feeling among all classes of reflecting minds here, an admiration for the dignified and gentlemanly bearing with which you have gone through the contest and rebuked the ruffian onslaught,--and to say, moreover, that we should, I have no doubt, all unite, from all sides, as one man, in sending you back to the Senate, should the maniac threats of expulsion by any possibility be carried into effect."
