Captain Harleston, with detachment of Company D, who have gone to Morris Island for the past three nights to month two 10-inch columbiads, had to be brought over this morning in small boats at 3 o'clock August 1, the steamer being unable to go from them. The provisions for Charleston Battalion were carried in same manner.

August 2.-At 1 p. m. the enemy commenced a rapid bombardment of Battery Wagner from his mortars; we replied vigorously, and the enemy slackened their fire in about one hour.

The following ammunition was expended, viz: 32-pounder rifle shells, 2; 7-inch rifle shells, 10; 10-inch columbiad shells 30; 10-inch mortar shells, 13; 9-inch Dahlgren shells, 12; 8-inch columbiad shells, 40.

The engineer work is still progressing, and five rooms on upper floor are filled; two are in progress. The wharf sunk so much yesterday, that it broke in, and it is now dangerous to carry heavy guns on it to be shipped. It is now being repaired. Captain Harleston, with a detachment of Company D, again went to Morris Island last night and succeeded in mounting the second 10-inch columbiad.

Two mechanics have been sent from this post to repair guns at Battery Wagner. The ammunition for Battery Wagner had to be carried from this post last night by a crew detailed from this garrison with our post.

The steamer Sumter was driven away from Morris Island last night. She was forced to return here without landing provisions. A crew was detailed from this garrison, and the rations and ordnance stores were carried over in barges. The signals on arrival and departure of Sumter at Morris were signaled by the enemy with a single rocket from apparently the position where the steamboat Manigault was burned.

The engineer work is still progressing,but no more rooms have been completed. One mortar and bed were taken down from the terre-plain and is now ready for shipment.
