--The enemy's operations during the last twenty-four hours have been mostly confined to a steady and continuous bombardment of Fort Sumter
from their Parrott guns on Morris Island
Their fire begins to tell upon Sumter
, which replies only at long intervals.
The defence of the throat this harbor does not depend mainly upon Sumter
, even if that fortress should eventually be battered down.
The harbor entrance is still effectually guarded by powerful sand batteries on Sullivan's Island
But few casualties yesterday.
