From Middle Tennessee.
The rumor that Rosecrans has evacuated Murfreesboro' is doubted by the Chattanooga Rebel. That paper says that of the movement of the Federal in the direction of Columbia, however, there seems to be no doubt. "It is possible the intention of Rosecrans is to occupy lower central Tennessee and either to force our troops upon the line of the river or to unite with Grant." The Winchester Bulletin of Wednesday, says that a small detachment from Gen. Morgan's command have just retraced from a tour in Kentucky, having in the short space of twenty-one days traveled over five hundred miles, being surrounded by the Yankees on two or three different occasions, and captured and destroyed Government property to the amount of over half million of dollars — and all without the loss of a man killed or wounded.
