The annual State Convention of the Free-Soil Party of Massachusetts met at Lowell September 15, 1852. It was organized with the following officers: Hon. Stephen C. Phillips, of Salem, President,--Rodney French, of New Bedford, George B. Atwood, of Taunton, William Jackson, of Newton, George F. Williams, of Boston, Charles Beck, of Cambridge, John B. Alley, of Lynn, Benjamin F. Thompson, of Winchester, John Nesmith, of Lowell, John Edgell, of Gardner, Francis Bates, of Springfield, Calvin Marden, of Pittsfield, Vice-Presidents,--George M. Brooks, of Concord, Edmund Anthony, of New Bedford, William S. Robinson, of Lowell, Andrew J. Aiken, of Adams, Benjamin F. White, of Weymouth, Secretaries. Eloquent speeches were made by the President, Hon. S. C. Phillips, Hon. Henry Wilson, Hon. John W. Graves, Hon. E. L. Keyes, Hon. Rodney French, Dr. Caleb Swan, Richard H. Dana, Jr., Esq., Hon. Horace Mann, Hon. Amasa Walker, Hon. Anson Burlingame, and Seth Webb, Jr., Esq. The resolutions adopted by the Convention were reported by Hon. C. F. Adams. Hon. Horace Mann was nominated as candidate for Governor, and Hon. Amasa Walker as candidate for Lieutenant-Governor. Early in the proceedings Mr. Sumner was introduced to the audience by the President. This incident is copied from the report in the papers, as is also the speech which he made, with the interruptions. "The President remarked, that there was one gentleman present whom the Convention would all delight to hear: he alluded to our distinguished Senator in Congress, Hon. Charles Sumner. "The name of Mr. Sumner was received with 'three times three' rousing cheers, and the waving of hats, canes, handkerchiefs, &c.; which demonstrations of regard were renewed as he made his appearance on the platform." Among those on the platform was Captain Drayton, called "The Hero of the Pearl," recently liberated from prison through the exertions of Mr. Sumner (_ante_, p. 49), who took his seat "amid the hearty cheers of the whole assembly." MR. PRESIDENT, AND FELLOW-CITIZENS OF MASSACHUSETTS:-- I should be dull indeed,--dull as a weed,--were I insensible to this generous, heart-speaking welcome. After an absence of many months, I have now come home to breathe anew this invigorating Northern air [_applause_], to tread again the free soil of our native Massachusetts [_cheers_], and to enjoy the sympathy of friends and fellow-citizens. [_Renewed applause._] But, while glad in your greetings, thus bounteously lavished, I cannot accept them for myself. I do not deserve them. They belong to the cause [_applause_] which we all have at heart, and which binds us together. [_Cheers._]
