At the nomination of General Taylor, Hon. Charles Allen and Hon. Henry Wilson, of Massachusetts, delegates to the National Convention, both refused to support the candidate. This was the signal for movement. A call was issued for a convention to found a new party. It was signed by Mr. Sumner and those with whom he was in the habit of acting. This was the beginning of the separate Free-Soil organization in Massachusetts, which afterwards grew into the Republican party. The call, which was extensively signed, concluded by inviting "fellow-citizens throughout the Commonwealth, who are opposed to the nomination of Cass and Taylor, to meet in convention at Worcester, on Wednesday, the 28th day of June current, to take such steps as the occasion shall demand in support of the PRINCIPLES to which they are pledged, and to coöperate with the other Free States in a convention for this purpose." It will be observed that the people were summoned to support _principles_ and also to coöperate with the Free States generally in this behalf. The response was prompt and enthusiastic. As many as five thousand persons appeared at Worcester, quickened by hostility to Slavery. The City Hall was not large enough, and the excited multitude adjourned to the Common, where they were called to order by Alexander DeWitt, of Oxford. Samuel F. Lyman, of Northampton, was chosen Chairman _pro tem._, and W.S. Robinson, of Lowell, Secretary _pro tem._ A committee, of which Hon. E.L. Keyes, of Dedham, was chairman, reported the following list of officers: Hon. Samuel Hoar, of Concord, President; David Heard, of Wayland, Alanson Hamilton, of North Brookfield, Joseph L. Richardson, of Medway, Dr. S.G. Howe, of Boston, John Wells, of Chicopee, Joseph Stevens, of Warwick, and R.P. Waters, of Salem, Vice-Presidents; William S. Robinson, of Lowell, William A. Wallace, of Worcester, Allen Shepard, of Ashland, William A. Arnold, of Northampton, Secretaries. On motion of Hon. S.C. Phillips, of Salem, a committee was appointed to draft an address and resolutions, consisting of Mr. Phillips, Erastus Hopkins, of Northampton, D.W. Alvord, of Greenfield, M.M. Fisher, of Medway, A.C. Spooner, of Boston, A. Bangs, of Springfield, and E. Rockwood Hoar, of Concord. The Convention was first addressed by Samuel Hoar, on taking the chair,--then by Charles Allen, Henry Wilson, Abraham Payne, of Rhode Island, Charles Hart, of Rhode Island, J.C. Woodman, of Maine, Amasa Walker, Lott Poole, Joshua Leavitt, Lewis D. Campbell, of Ohio, Joshua R. Giddings, of Ohio, J.C. Lovejoy, Charles Francis Adams, Charles Sumner, Edward L. Keyes, and E. Rockwood Hoar. The speeches were earnest and determined, and they were received in a corresponding spirit. No great movement ever showed at the beginning more character and power. It began true and strong.
