Stand firm, Freemen of Massachusetts! Your fidelity now will be the cement of our new organization, and a token of that mutual confidence which shall assure speedy success. Ours is the cause of truth, of morals, of religion, of God. Let us be united in its support! "A stout heart, a clear conscience, and never despair." These were the last words addressed in writing by JOHN QUINCY ADAMS to a person deeply interested in our movement. Let us each consider them addressed directly to himself. CHARLES SUMNER, _Chairman_.

A LAST RALLY FOR FREEDOM. LETTER TO THE CHAIRMAN OF THE FREE-SOIL MEETING AT FANEUIL HALL, NOVEMBER 9, 1848. Besides speaking at all the principal centres in the State, Mr. Sumner made what was called a "campaign speech" at Faneuil Hall on the evening of October 31st, occupying the whole evening. John A. Andrew, Esq., was in the chair. Of this meeting, and of Mr. Sumner's speech, the _Boston Republican_ used strong language. "Mr. Sumner's reception was most gratifying. The cheering was long continued and unanimous, and burst forth at intervals during the speech, which was of surpassing ability and eloquence. During the peroration the audience attained the highest pitch of enthusiasm; deafening and tumultuous shouts resounded, cheer upon cheer, until it seemed as if they would never stop." Though this speech was never reported, Mr. Sumner was not inclined to speak again in Faneuil Hall before the election, when he found himself advertised for another meeting on the evening of November 9th. The notice was in these words, which were duly capitalized: "Rally to Faneuil Hall! Adams and Sumner, Richard H. Dana, Jr.! Once more to the rescue!" Mr. Adams and Mr. Dana spoke, but Mr. Sumner appeared by letter. In the absence of the last, Mr. Adams alluded to him as a candidate in language which belongs to this record.
