The defeat of Mr. Burlingame, as a Representative of Boston, which was keenly felt by Republicans, and especially by Mr. Sumner, opened the way to his wider career as Minister of the United States to China, and then as Minister of the Chinese Empire to the Western Powers. The vote stood 8,014 for Hon. William Appleton, and 7,757 for Mr. Burlingame.

Boston, November 9, 1860.

DEAR SIR,—An engagement out of the State will prevent me from uniting with the gallant Wide-Awakes this evening in their festival at Music Hall. But my heart will be with them in their joy and in their sorrow.

They will naturally rejoice in that great victory by which the American people have solemnly declared that Slavery is sectional and Freedom is national, so that, wherever Slavery exists, if it exist at all, it must be by virtue of local law, and not by virtue of the National Constitution.

But even this victory, opening a new epoch in our national history, cannot make us forget the backsliders of Boston, through whose desertion of principles the delegation in Congress, pledged to Freedom, has been weakened, and a blow struck at an eminent Representative which has fallen upon the hearts of Republicans everywhere throughout the country. To the honor of Mr. Burlingame, all good Republicans feel wounded through him; and it is also to his honor that he was made the mark of special assault.

All experience shows that the partisans of Slavery stick at nothing, where the imagined interests of Slavery are in question. The essential brutality of Slavery showed itself lately in New York, when Marshal Rynders personally assaulted a venerable citizen who appeared at his office on public business, cursing him with most blasphemous oaths; and it showed itself here in Boston, when the supporters of Mr. Appleton for weeks traduced the Republican candidate, uttering calumnies which were as basely false with regard to him as if they had been uttered in detraction of Mr. Appleton. Such conduct must make us hate Slavery more, and add to our mortification that it prevailed among us.

It belongs to the Republican party, at last triumphant in the nation, inflexibly to sustain its principles, and also to sustain the men who are true to these principles. In this duty I doubt not it will be guided by that temperate judgment which is in harmony with the consciousness of right.

God bless the Wide-Awakes! And believe me, dear Sir,

Faithfully yours,

Charles Sumner.
