That our own country is open to the same reproach, is patent to all
the world. The United States has not that shield of defensive power
behind which time can be gained to develop its reserve of strength. As
for a seafaring population adequate to her possible needs, where is
it? Such a resource, proportionate to her coast-line and population,
is to be found only in a national merchant shipping and its related
industries, which at present scarcely exist. It will matter little
whether the crews of such ships are native or foreign born, provided
they are attached to the flag, and her power at sea is sufficient to
enable the most of them to get back in case of war. When foreigners by
thousands are admitted to the ballot, it is of little moment that they
are given fighting-room on board ship.

Through the treatment of the subject has been somewhat discursive, it
may be admitted that a great population following callings related to
the sea is, now as formerly, a great element of sea power; that the
United States is deficient in that element; and that its foundations
can be laid only in a large commerce under her own flag.

V. National Character.--The effect of national character and
aptitudes upon the development of sea power will next be considered.

If sea power be really based upon a peaceful and extensive commerce,
aptitude for commercial pursuits must be a distinguishing feature of
the nations that have at one time or another been great upon the sea.
History almost without exception affirms that this is true. Save the
Romans, there is no marked instance to the contrary.

All men seek gain and, more or less, love money; but the way in which
gain is sought will have a marked effect upon the commercial fortunes
