Thus, Sir, standing at the very grave of Freedom in Nebraska and Kansas, I lift myself to the vision of that happy resurrection by which Freedom will be assured, not only in these Territories, but everywhere under the National Government. More clearly than ever before, I now penetrate that great Future when Slavery must disappear. Proudly I discern the flag of my country, as it ripples in every breeze, at last in reality, as in name, the Flag of Freedom,--undoubted, pure, and irresistible. Am I not right, then, in calling this bill the best on which Congress ever acted? Sorrowfully I bend before the wrong you commit. Joyfully I welcome the promises of the Future. When Mr. Sumner took his seat, he was succeeded by Mr. MASON, of Virginia, who spoke as follows. I understand that the petitions which the Senator [Mr. SUMNER] who has just taken his seat offers were to be admitted, as they were offered, by the unanimous consent of the Senate. Two of them, when offered, were sent to the President's table. The last he has reserved, and made the vehicle for communicating the sentiments of the pulpits of New England to the Senate, on the subject of this bill. I object to its reception; and I object to it because I understand that Senator to say that it is _verbatim_ the petition that was presented by his honorable colleague, who is not now with us, in which the clergy presented themselves in this Senate and to the country as a third estate, speaking not as American citizens, but as clergymen, and in that character only. I object to its reception. I object to it, that I may not in any manner minister to the unchristian purposes of the clergy of New England, as the Senator has just announced them. I object to it, that I may be in no manner responsible for the prostitution of their office (once called holy and sacred, with them no longer so) in the face of the Senate and of the American people. I object to it, that the clergymen of my own honored State, and of the South, may, as holding a common office in the ministry of the Gospel, be in no manner confounded with or contaminated by these clergymen of New England, if the Senator represents them correctly.
