Fort Sumter.
--The Washington correspondent of the Baltimore Sun says that Gen. Scott, in reply to a letter from a Southern citizen, stated that Sumter is to be evacuated.--A Washington dispatch says:‘ The facts are, that a messenger has been sent to Sumter to announce the decision of the President and the Cabinet to Major Anderson, who will communicate it to Gov. Pickens; but the mode of evacuation has not yet been decided upon. Gen. Scott favors the garrison coming overland to Washington, whilst the President prefers they should be brought to Fortress Monroe in a steamer direct from the fortress.
’ Three soldiers, who obtained their discharge from Fort Sumter, arrived in New York Wednesday. They say Maj. Anderson is short of both provisions and fuel. According to one of their statements, there are twenty-five more men whose term of service expires this day, Wednesday, 13th. He says that none of them will re enlist.
