We have thus given the statistics of the sailing vessels of the navy. We now give a table of the steam vessels of all descriptions in our navy, which are the most valuable auxiliaries we have. It is probably the most effective steam navy in the world, and in its department of huge iron-clads cannot be excelled even by the navies of the old world. The steam vessels of our navy may thus be enumerated:

STEAM FRIGATES—9.
