The floating battery, finished, mounted, and manned at Charleston, was taken out of the dock last evening, and anchored in the cove, near Sullivan's Island. The people are not excited, but there is a fixed determination to meet the issue. The Convention has just adjourned, subject to the call of the president. Before adjourning, it passed resolutions approving the conduct of General Twiggs in resigning his commission and turning over the public property under his control to the authorities. Governor Pickens was in secret session with the Convention. About 1,000 troops were sent to the fortifications to-day; 1,800 more go down to-morrow. Messrs. Wigfall, Chesnut, Means, Manning, McGowan, and Boyleston, have received appointments in General Beauregard's staff. A large number of the members of the Convention, after adjournment, volunteered as privates. About 7,000 troops are now at the fortifications. The beginning of the end is coming to a final closing. Fort Sumter will be attacked without waiting for the fleet. Every thing is prepared against a land attack. The enthusiasm is intense, and the eagerness for the conflict, if it must come, unbounded.--N. Y. Day Book.
The officers of the District of Columbia militia were ordered to meet at 10 o'clock A. M., in consequence of information relative to a contemplated movement for the seizure of the city of Washington by the secessionists under Ben McCullough. Orders were issued for the militia to assemble at their armories. Seven militia companies reported to General Scott, and between six and eight hundred of then volunteered for any service in which the President might desire them to act.--Times, April 11.
