[special Dispatch to the Richmond Dispatch.]
Washington rumors.
Washington, Jan. 8.
--A dispatch, it is said, has been received from Charleston, stating that Major Anderson being notified that Federal troops were on their way to reinforce him, wrote a letter to the commander at Fort Moultrie, saying that if the steamer was interrupted he would fire on that fort.
The reply he received is said to have been a defiant one.
The President promised Hon. A. R. Boteler, of Virginia, that no troops should be sent to Harper's Ferry. Seventy-five, however, have been sent there, Zed.
