Refugees.
--The Chattanooga (Tenn.) Rebel has information that Hon. A. O. P. Nicholson, Judge Wm. L. Martin, and Jos. Branch, brother of Gen. Branch, of North Carolina, all citizens of Maury county, Tenn., have arrived safely South of the line, having been expelled from their homes by order of Gen. Negley. They represent the people of Middle Tennessee as more united and determined in their hostility to Federal tyranny than at any time since the war commenced; that all feel the Rubicon is passed, and that we have no alternative but in liberty or death.
