Mr. Foote, of Miss., made a very long speech on the general subject of slavery, and especially slavery in the District of Columbia. The attempt to legislate indirectly--that is, to sustain freedom of discussion in the District--against slavery, was an outrage upon the rights of the South. If any man gives countenance to this bill, he said, I pronounce him to be no gentleman--he would, upon temptation, be guilty of highway robbery on any of the roads of the Union. He charged that the abduction of the Drayton-Soyer slaves was instigated or countenanced by a member of the United States Senate--meaning Mr. Hale. This bill is intended to cover negro-robbery. The New Hampshire senator is endeavoring to get up civil war and insurrection. Let him go South. Let him visit the good State of Mississippi. I invite him there, and will tell him beforehand, in all honesty, _that he could not go ten miles into the interior before he would grace one of the tallest trees of the forest, with a rope around his neck, and if necessary_, I should myself assist in the operation! MR. HALE.--I did not anticipate this discussion, yet I do not regret it. Before proceeding further, let me say that the statement that I have given the slightest countenance to the recent "kidnapping of slaves is false." MR. FOOTE.--It had been stated so to me and I believed it. I am glad to hear the senator say he had no connection with the movement--some of his brethren doubtless had. MR. HALE.--The sneer of the gentleman does not affect me. While I am up, let me call the attention of the Senate to a man, who I am proud to call my friend, the editor of the "National Era." Mr. Hale read a card of Dr. Bailey's in the "Intelligencer," declaring his entire ignorance of the abduction of the slaves till they were returned. MR. CALHOUN.--Does he make denunciation of the robbery? MR. HALE.--He had quite enough to do in defending himself, and it was no part of his duty to denounce others. MR. CALHOUN.--I understand that. Mr. Hale went on to refer to Mr. Foote's invitation of hanging in Mississippi, and would, in return for the hospitality, invite the senator to come to New Hampshire to discuss this whole subject, and he would there promise him protection and rights. He defended his bill as containing simply the plainest provisions of the common law; yet the South Carolina senator was shocked at his temerity. MR. BUTLER.--Will the senator vote for a bill, properly drawn, inflicting punishment on persons inveigling slaves from the District of Columbia? MR. HALE.--Certainly not; and why? Because I do not believe slavery should exist here. MR. CALHOUN.--He wishes to arm the robbers and disarm the people of the district.... I will take this occasion to say, that I would just as soon argue with a maniac from Bedlam as with the senator from New Hampshire.
