Emerson Etheridge, of Tennessee, addressed the citizens of Louisville, Ky., on the great questions which are dividing the South at the present time. He commenced his address with an allusion to the distracted condition of the country, congratulating himself and his audience that he stood upon Kentucky soil, a State that was yet loyal to the Union. He clearly proclaimed himself for his country, first, last, and forever. Having but recently come from a State in which anarchy reigned supreme, he could the better appreciate the blessings of political liberty which were yet vouchsafed to Kentuckians, and which he felt Kentuckians had the patriotism, the gallantry, and the power to perpetuate. He drew a picture of Kentucky in her proud position as a sister in the Union of the States, of her wealth, of her usefulness as an asylum for the oppressed of both sections of our unhappy and divided country, and of her grandeur in after days when she has safely outridden the storm which wrecked the frailer sisterhood around her. While he dealt deadly blows to the apologists of dissolution, he spoke cheering words of comfort and assurance to the friends of the Union. He was withering in his denunciation of rebellion, powerful in argument, ready and illustrative in anecdote, and fervid and glowing in eloquence.--Louisville Journal, May 28.

George W. Thompson, one of the judges of the Circuit Court of the State of Virginia, issued a proclamation ordering the rebels in the western part of that State to disperse. Peculiar interest attaches to the document from the fact that one of Judge Thompson's sons, W. P. Thompson, a young lawyer, resident at Fairmont, is aide-de-camp to Gen. Thomas S. Iaymond, commander of the confederate forces in Western Virginia, and the leader of the first company which marched on Grafton. Another of his sons is also a secessionist, and a private in the same company.--(Doc. 201.)
