Colonel and Assistant Adjutant-General.
Inquire why the signal officers with corps do not report through the chief signal officer at these headquarters.
GEO. G. MEADE.
HDQRS. ARMY OF THE POTOMAC, SIGNAL DEPARTMENT, August 3, 1864.
Chief of Staff:
GENERAL: I have the honor to report no movement of the enemy's force visible to-day from our stations. They were busily working upon the earth-work about three-quarters of a mile south of the lead-works, which seems to be a large one. One train of cars passed into the city on the Weldon railroad. Several wagons passed on the road near Weldon railroad during the day. They have been bringing considerable timber to the work near the Gregory Chimneys.
Very respectfully, your obedient servant,
B. F. FISHER,
Captain and Chief Signal Officer.

A. A. HUMPHREYS,
Major-General and Chief of Staff.
GENERAL: I received no reports from the officers at corps headquarters and know nothing of the reported movement of cavalry. My lookouts at the plank road station and on the extreme right reported no movement visible to-day.
