A large and enthusiastic public meeting of unconditional Union men was this evening held in the city of Leavenworth, Kansas. Speeches were made by General Blunt, and others, and loyal resolutions were unanimously adopted, proclaiming “all who ask for peace with  rebels in arms against the Government, except on the terms of unconditional submission to the Constitution and the laws, or who propose a separation of the Union in any manner,” to be traitors, and indorsing the President's Emancipation Proclamation.
Yesterday, about one o'clock in the afternoon, a squad of Baylor's rebel cavalry attacked a small scouting-party of twelve men, of the Twelfth Pennsylvania cavalry from Kearneysville, near Smithfield, Va., killing one, wounding two, and capturing four men and several horses. About four o'clock P. M., General Kelly's scouts from Harper's Ferry, Md., fell in with the same party a few miles south of Charlestown, and after a running fight of several miles recaptured the men and horses, and captured Lieutenant Baylor, two of his men, and several horses.--General Kelly's Despatch.
A skirmish took place to-day in the vicinity of Bolivar, Tenn., between a detachment of National cavalry and a body of rebels, in which four of the latter were killed, five taken prisoners, and a number wounded.
