The Brooklyn is at present hourly expected at Charleston, and may take an active part in any future contest at that point. She was launched at New York on the 27th of July, 1858, and took her place in the navy on the 1st of January, 1859. She is by far the largest sloop of war in our navy, or in the world, and carries the heaviest battery ever placed on the deck of any vessel of her class; yet she only draws 16 feet water. Her length on deck is 247 feet, breadth of beam 43 feet, depth of hold 21 ½ feet, being 2000 tons, government measurement; and is rated at 14 guns on the navy register, although pierced for 24 9-inch shell guns and two 10-inch pivot guns, the weight of each being nearly six tons. All the hatch and mast combings on this deck are of mahogany--a wood never before used for such a purpose in our navy. All the spare spars required, together with three boats, are carried upon a bridge amidships, elevated above the deck sufficiently high to walk under, which is an entirely new arrangement. By this improvement the space upon deck is kept clear and unobstructed for working the guns. Her entire complement is about 300 men. The captain's cabin occupies the space of 25 feet in length at the after end of this deck. The boilers are Martin's patent, now generally adopted in the naval service. Her propeller is of composition, 14 feet 6 inches in diameter, and weighing 13,500 pounds. It is arranged for hoisting on deck when not needed; and can be taken out of water by means of a capstan, arranged for the purpose, in less than two minutes. She is sparred precisely like sailing vessels of similar tonnage in the merchant service, her screw being merely an auxiliary affair. Her speed is estimated at ten knots under steam.
