The change that has taken place in naval vessels and naval warfare
since the introduction of steam as a motive power for ships of war
demands either a corresponding change in some of our existing navy
yards or the establishment of new ones for the construction and
necessary repair of modern naval vessels. No inconsiderable
embarrassment, delay, and public injury have been experienced from
the want of such governmental establishments. The necessity of such
a navy-yard, so furnished, at some suitable place upon the Atlantic
seaboard has on repeated occasions been brought to the attention of
Congress by the Navy Department, and is again presented in the report
of the Secretary which accompanies this communication. I think it my
duty to invite your special attention to this subject, and also to
that of establishing a yard and depot for naval purposes upon one of
the Western rivers. A naval force has been created on those interior
waters, and under many disadvantages, within little more than two
years, exceeding in numbers the whole naval force of the country at
the commencement of the present Administration. Satisfactory and
important as have been the performances of the heroic men of the Navy
at this interesting period, they are scarcely more wonderful than the
success of our mechanics and artisans in the production of war
vessels, which has created a new form of naval power.

Our country has advantages superior to any other nation in our
resources of iron and timber, with inexhaustible quantities of fuel
in the immediate vicinity of both, and all available and in close
proximity to navigable waters. Without the advantage of public
works, the resources of the nation have been developed and its power
displayed in the construction of a Navy of such magnitude, which has
at the very period of its creation rendered signal service to the
