A gentleman from Charleston says that everything there (Jan. 7, 1861,) betokens active preparations for fight. Last Sunday, he says, not a lady was at the church he attended. They were all at home making cartridges and cylinders, and scraping lint. The thousand negroes busy in building batteries, so far from inclining to insurrection, were grinning from ear to ear at the prospect of shooting the Yankees. Extravagant reports were current as to the hostile designs of the Federal Government, such as that the Macedonian was on her way with five hundred troops.
