were placed immediately after dark in position, being removed from Battery Numbers 3. I made a reconnaissance from opposite Fort Clifton to Battery Numbers 1; found the right bank for the most part swamp, except from Rowlett's to the battery.

June 30, no regular approaches have been made, as, until we invest the town, it would be almost useless, for the enemy can fortify to the rear as fast as we can approach. No details of batteries are sent in drawing, because for the most part they are irregular, having been made out of the infantry parapets strengthened. In the sketch our lines are marked in double red lines, the enemy's in back. On the map are the dates that each line was taken up.

The following officers of the Engineer Corps are on duty in this department; Captain Francis U. Farquhar, chief engineer, Eighteenth Army Corps; First Lieutenant Peter S. Michie, assistant engineer, Department of Virginia and North Carolina; First Lieutenant William R. King, chief engineer, District of North Carolina.

I have the honor to be, general, very respectfully, your obedient servant,

G. WEITZEL,

Brigadier-General and Chief Engineer.

Bvt. Major General J. G. BARNARD,

Chief Engineer, Armies in the Field.
