The Free-Soil party, having assumed the name of Republican party, held its Annual Convention at Worcester, September 7, 1854. It was organized by the following officers: Hon. Robert Rantoul, of Beverly, the venerable father of the late Mr. Rantoul, as President; George R. Russell, of West Roxbury, B.W. Gage, of Charlestown, Samuel Hopkins, of Northampton, Charles Shute, of Hingham, Albert Currier, of Newburyport, Warren Lovering, of Medway, Adam Harrington, of Shrewsbury, Francis Watkins, of Hinsdale, Robert Sturtevant, of Savoy, Asaph Churchill, of Dorchester, Richard P. Waters, of Beverly, William Washburn, of Boston, Charles Beck, of Cambridge, Benjamin B. Sisson, of Westport, Joel Shed, of Bridgewater, Augustus Morse, of Leominster, Foster Hooper, of Fall River, Levi Reed, of Abington, John A. Andrew, of Hingham, Vice-Presidents; Joseph Denny, of Worcester, William H. Harris, of Worcester, E.W. Stacy, of Milford, Charles R. Ladd, of Chicopee, William H. DeCosta, of Charlestown, Secretaries. At the same Convention Hon. Henry Wilson was nominated for Governor, and Hon. Increase Sumner for Lieutenant-Governor. John A. Andrew, Esq., was made Chairman of the State Committee.

Mr. Sumner's reception in the Convention was quickened by recent events in which he had borne part. It is thus described in a report of the Convention.

"At this point the Hon. Charles Sumner entered the hall. His reception was such as is rarely accorded to a public man. The whole vast audience rose as one man to welcome him, and the most deafening cheers of welcome resounded for several minutes. We have never seen a more hearty and enthusiastic demonstration in honor of any man. It was the spontaneous homage of true men to the man who had upheld the Freedom standard and carried it into the thickest of the fight,—to the man who had upheld the honor of Massachusetts in the Senate, vindicated her opinions, and thrown back upon her assailants the taunts and insults which they had never ceased to heap upon her. The cheering, as our Senator appeared upon the platform and took his seat, was loud and long continued."

Mr. Sumner was at once called to speak. His speech is given as reported by the Boston Traveller, which ran a special train in one hour from Worcester, a distance of forty miles, in order to lay it before the public without delay.

In this speech Mr. Sumner had two objects,—first, to vindicate the necessity of the Republican party, and, secondly, to destroy the operation of the Fugitive Slave Act in Massachusetts, showing especially that citizens are not constrained to its support. His position with regard to the oath to support the Constitution was much discussed at the time, and the National Intelligencer, in elaborate articles by Mr. Gales, undertook to call him to account. To the latter he replied by letter. The speech had an extensive circulation.

Mr. Sumner came to the Convention at the invitation of Mr. Andrew, Chairman of the Provisional State Committee, whose first letter, dated July 22, 1854, was as follows.

"You will have seen, before receiving this note, the report of the meeting at Worcester, at which a new party was begun, and the steps preliminary to a State nominating convention taken. I think, in spite of strong opposition from the Whig presses and fuglemen, who cannot bear to give up their factitious powers and influence, that there is a great popular movement commenced, which may, under proper cultivation, disclose a splendid result in the fall. But more depends upon the aid you can give than upon that of any one man. Your recent battles in the Senate have shut the mouth of personal opposition, wrung applause from the unwilling, excited a State's pride and gratitude, such as rarely it is the fortune of any one to win. Your presence at the nominating convention, to be held on the 10th of August,—probably at Springfield,—is a point which must be agreed to at once. It will secure a most triumphant meeting, certainly in point of numbers and enthusiasm. I want you to write to me at once, permitting me to say to any of our friends that you will attend the meeting. A speech of half an hour, or an hour, is all that you need make, though you could have three hours, if you would use them.... I am bold, speak urgently, since I am, as Chairman of the Provisional State Committee, officially responsible for the utmost exertions to serve the cause in this behalf."

This was followed by another letter from Mr. Andrew, dated August 28, 1854, as follows.

"I, however, wish to have the authority now to say definitely to all inquirers that you will be present on the 7th, and address the convention, and I wish this to be considered as a formal and official invitation. There are constant references made to the hope of seeing and hearing you there, on all hands. Everybody counts for that gratification. And we can do nothing which will so completely secure a triumphant gathering as to announce your name. The whole Free-Soil party, proud of your recent achievements, and grateful for the many exhibitions of your devotedness to our principles at all times of hazard and necessity, and the people of all parties, who feel you to have been the most conspicuously representative man to whom Massachusetts has intrusted her interest in Congress since the death of John Quincy Adams, are alike anxious to greet you.

"I do not wish you to feel under the necessity of preparing for one of your greatest speeches. No one will demand that of you. They only want you to come, and to say what seems to yourself proper to say at the time."
