of the Commission, to connect with the system of defenses already established forts and batteries for the defenses of the Potomac.
Such works, though of earth and timber, must necessarily be expensive; and, indeed, they should be so carefully planned that hereafter the may be convered into permanent works, if desirable.
I am, very respectfully, your most obedient,

Major N. H. MCLEAN,
Chief of Staff, Department of the Ohio:
MAJOR: I have the honor to hand you herewith copy of a dispatch of this date, just received from General Scammon,* which conveys information leading to the belief that the rebel forces in his front are being reduced in number, on learning (as they no doubt have done) of the reduction of our force in the Kanawha Valley. I also learn that the storms of the past week have so obstructed the mountains with snow, and injured roads, that there is no anticipation of activity for some time on either side in that region.
Very respectfully, your obedient, servant,
