The signal services which have been rendered by our Navy and the
capacities it has developed for successful cooperation in the national
defense will give to that portion of the public force its full value in
the eyes of Congress, at an epoch which calls for the constant vigilance
of all governments. To preserve the ships now in a sound state, to
complete those already contemplated, to provide amply the imperishable
materials for prompt augmentations, and to improve the existing
arrangements into more advantageous establishments for the construction,
the repairs, and the security of vessels of war is dictated by the
soundest policy.

In adjusting the duties on imports to the object of revenue the
influence of the tariff on manufactures will necessarily present itself
for consideration. However wise the theory may be which leaves to the
sagacity and interest of individuals the application of their industry
and resources, there are in this as in other cases exceptions to the
general rule. Besides the condition which the theory itself implies of
a reciprocal adoption by other nations, experience teaches that so many
circumstances must concur in introducing and maturing manufacturing
establishments, especially of the more complicated kinds, that a country
may remain long without them, although sufficiently advanced and in some
respects even peculiarly fitted for carrying them on with success. Under
circumstances giving a powerful impulse to manufacturing industry it has
made among us a progress and exhibited an efficiency which justify the
belief that with a protection not more than is due to the enterprising
citizens whose interests are now at stake it will become at an early day
not only safe against occasional competitions from abroad, but a source
of domestic wealth and even of external commerce. In selecting the
branches more especially entitled to the public patronage a preference
is obviously claimed by such as will relieve the United States from a
dependence on foreign supplies, ever subject to casual failures, for
articles necessary for the public defense or connected with the primary
wants of individuals. It will be an additional recommendation of
particular manufactures where the materials for them are extensively
drawn from our agriculture, and consequently impart and insure to that
great fund of national prosperity and independence an encour
