From Atlanta.
Atlanta, August 14.
--The enemy opened fire upon the city with six batteries at eight o'clock last night, their batteries being stationed on the Marietta, Peachtree and Williams's Mills roads, and in front of the Medical College and Rolling Mills.
The fire was very heavy, and continued till 4 o'clock A. M. About midnight a shell entered the frame storehouse of Briggins & Co., Marietta street, setting fire to some loose cotton.
The flames spread rapidly, and the building was soon in flames.
The fire-bell was rung, and engine No. 3 replied promptly.
The enemy immediately concentrated their fire on that point.
The firemen nobly stood their ground, and, despite the rain of shell, succeeded in saving the large warehouse of Kegle & Co.; other buildings on the square were consumed.
Noe a citizen was injured, the woman and children having sought safety in the bomb-proofs.
There is but little shelling along the entire line to-day, and no movement of the enemy is reported.
