East Tennessee.
--Our last Tennessee exchanges seem to be confident that an engagement cannot be long delayed between the forces of Long street and Schofield. The Yankees have advanced to Russellville to force, and are running the cars from Knoxville as far East as Morristown. A skirmish between the enemy's cavalry and our own, took place at Whitesburg, 22 miles below Greenville, on Tuesday, in which we are reported to have lost eight killed. The Yankee loss is not stated. Stirring times are hourly looked for.
