--The enemy have been unusually active during the past sixteen hours. About four o'clock yesterday afternoon a heavy assault was made upon the works held by our skirmishers upon the extreme left.
After some stubborn fighting they succeeded in gaining possession of the position there, but subsequently were driven from it, and our lines were re-established.
About 10 o'clock last night an assault was also made on our skirmish lines, extending from the centre to the extreme left; but the movement having been anticipated, resulted in a complete failure.
Brisk skirmishing continued throughout the night up to the present time.
Our loss in both affairs is insignificant.
There was comparative quiet in the city last night and but few shells were thrown, resulting in no damage.
