No firing on-Sumter yesterday or to-day, and very little firing between the batteries.
Four shells were thrown into the city between two and three o'clock this afternoon, but no one was injured.
Thirteen Yankee prisoners, including three commissioned officers of the United States brig Perry, captured at Merrill Inlet by the 21st Georgia cavalry, have arrived here and been committed to jail.

Nothing new this morning.
[third Dispatch.]
Charleston, Dec. 14.
