July 18 (to Brigadier-General Jordan).-I have the honor to forward the following extract from journal kept at this post, in compliance with Special Orders, Numbers 141, department headquarters:

July 17, at 2 p. m., the long roll was beaten. After remaining at battery for thirty minutes, and seeing no signs of an attack, the recall was sounded. This morning the shifting of a 32-pounder rifled gun from northwest cesemate battery to gorge battery was completed. At 6 a. m. one 10-inch sea-coast mortar and bed, with 296 shells, was shipped to Sullivan's Island.

At 6.30 p. m. the steamboats arriving at this wharf were fired into from a land battery on Morris Island.

This is the first shot fired from land in the direction of this fort. We replied by bursting 4 percussion shells on the island. The engineer work is progressing. Preparations are being made to re-enforce southern wall by filling officers' quarters with cotton bales and sand.
