The regulars cannot be spared from here. E. D. TOWNSEND, Assistant Adjutant-General. HAGERSTOWN, Mp., June 30, 1861. Major-General McCALL, Harrisburg, Pa.: I subjoin copy of telegram received from General McClellan, and will rely on you to send aid to Colonel Wallace if he calls for it before we can support him from this point: The two Pennsylvania State regiments are at State Line, ten miles from Cumberland. I recommend that one of them be ordered to Cumberland to support Wallace; the other to Piedmont. The two posts can communicate by the coal road via Lonaconing, and can draw their supplies from this direction. I move to-morrow on the main force in my front.
