The Ohio is, as far as I am a judge, the perfection of a ship of the line. But in every class you cannot but admire the superiority of the models and workmanship. The dock-yards in America are small, and not equal at present to what may eventually be required, but they have land to add to them if necessary. There certainly is no necessity for such establishments or such store-houses as we have, as their timber and hemp are at hand when required; but they ate very deficient both in dry and wet docks. Properly speaking, they have no great naval depot. This arises from the jealous feeling existing between the several states. A bill brought into Congress to expend so many thousand dollars upon the dock-yard at Boston, in Massachusetts, would be immediately opposed by the state of New York, and an amendment proposed to transfer the works intended to their dock-yard at Brooklyn. The other states which possess dock-yards would also assert their right, and thus they will all fight for their respective establishments until the bill is lost, and the bone of contention falls to the ground.
