Scouting.
--A writer says that the advance of the Federals in Tennessee has been greatly retarded by our scouts under Morgan and Scott. These intrepid fellows have performed many daring and wonderful feats. Morgan's command is an independent body of cavalry, at liberty to go and come as they please. Today they hover upon the front and flanks of the enemy; to-night they dash in upon a picket guard and capture all they do not kill; to-morrow they issue from the kills like the wind out of a cloud, and sweep before them reconnoitering parties who have ventured beyond their lines. We need more of these enterprising scouts.
