Many members rose, all addressing the Chair at the same time, and many members leaving the hall, and a general scene of noise and confusion prevailing. Mr. Rhett succeeded in raising his voice above the roar of the tempest which raged in the House, and invited the entire delegations from all the slave States to retire from the hall forthwith, and meet in the committee room of the District of Columbia. The Speaker again essayed to calm the House, and again standing up in his place, he recapitulated his attempts to preserve order, and vindicated the correctness of his own conduct--seemingly impugned by many. What his personal feelings were on the subject (he was from a slave State), might easily be conjectured. He had endeavored to enforce the rules. Had it been in his power to restrain the discussion, he should promptly have exercised the power; but it was not. Mr. Slade, continuing, said the paper which he wished to read was of the continental Congress of 1774. The Speaker was about to put the question on leave, when Mr. Cost Johnson, of Maryland, inquired whether it would be in order to force the House to vote that the member from Vermont be not permitted to proceed? The Speaker replied it would not. Then Mr. James J. McKay, of North Carolina--a clear, coolheaded, sagacious man--interposed the objection which headed Mr. Slade. There was a rule of the House, that when a member was called to order, he should take his seat; and if decided to be out of order, he should not be allowed to speak again, except on the leave of the House. Mr. McKay judged this to be a proper occasion for the enforcement of that rule; and stood up and said: "That the gentleman had been pronounced out of order in discussing slavery in the States; and the rule declared that when a member was so pronounced by the Chair, he should take his seat, and if any one objected to his proceeding again, he should not do so, unless by leave of the House. Mr. McKay did now object to the gentleman from Vermont proceeding any farther."
