I have said that we celebrate a birth, as well as a funeral. The birth is the new life of our country, born to-day into assured freedom, with all its attendant glory. The voice of the people at the ballot-box has echoed back that great letter of the President, “To whom it may concern” [_laughter and loud cheers_], declaring the integrity of the Union and the abandonment of Slavery the two essential conditions of peace. [_Loud applause._] Let the glad tidings go forth, “to whom it may concern,”--to all the people of the United States, at length now made wholly free,--to foreign countries,--to the whole family of man,--to posterity,--to the martyred band who have fallen in battle for their country,--to the angels above,--ay, and to the devils below,--that this Republic shall live, for Slavery is dead. This is the great joy we now announce to the world. [_Here there was a perfect torrent of approving cheers._] From this time forward, the Rebellion is subdued. Patriot Unionists in the Rebel States, take courage! Freedmen, slaves no longer, be of good cheer! The hour of deliverance has arrived. [_Renewed cheering._] JUBILEE OF LIBERTY. LETTER TO THE YOUNG MEN’S REPUBLICAN UNION OF NEW YORK, NOVEMBER 10, 1864. A public meeting, called a Jubilee, was held at the Cooper Institute, New York, to celebrate the recent victory at the polls. Among the letters read was the following. BOSTON, November 10, 1864. DEAR SIR,--It will not be in my power to meet with the Union citizens of New York at the “Jubilee” of Friday evening, according to the invitation with which you honor me. But my joy will mingle with theirs. The occasion you celebrate is worthy of jubilee, which in the Hebrew language is simply “the blast of a trumpet,” and now, in all languages, signifies “rejoicing.” The occasion is kindred to that famous jubilee in sacred history, when the mandate went forth, “_Proclaim Liberty throughout all the land_, unto all the inhabitants thereof: it shall be a jubilee unto you; and ye shall return every man unto his possession, and ye shall return every man unto his family.” And now this same mandate has gone forth, assuring the return of patriot Unionists to their possessions, and the return of patriot soldiers to their families, and crowning all with Universal Emancipation, sign and seal of union and peace. Such is the mandate of the American people in the reëlection of Abraham Lincoln. I pray that it may all be executed promptly and triumphantly. Thank God, the pettifoggers of compromise are answered by the people, who demand peace on the everlasting foundations of Union and Liberty. The political barbers, who undertake to prescribe, when they can only shave, are warned that their quackery is at an end. Accept my thanks and best wishes, and believe me, dear Sir, very faithfully yours, CHARLES SUMNER.
