_For what use is the Navy of the United States?_ The annual expense of our Navy, during recent years, has been upwards of six millions of dollars. For what purpose? Not for the apprehension of pirates, since frigates and ships of the line are of too great bulk for this service. Not for the suppression of the Slave Trade; for, under the stipulations with Great Britain, we employ only eighty guns in this holy alliance. Not to protect our coasts; for all agree that our few ships would form an unavailing defence against any serious attack. Not for these purposes, you admit; _but for the protection of our Navigation_. This is not the occasion for minute estimates. Suffice it to say, that an intelligent merchant, extensively engaged in commerce for the last twenty years, and who speaks, therefore, with the authority of knowledge, has demonstrated, in a tract of perfect clearness,[88] that the annual profits of the whole mercantile marine of the country do not equal the annual expenditure of our Navy. Admitting the profit of a merchant ship to be four thousand dollars a year, which is a large allowance, it will take the earnings of one hundred ships to build and employ for one year a single sloop of war, of one hundred and fifty ships to build and employ a frigate, and of nearly three hundred ships to build and employ a ship of the line. Thus more than five hundred ships must do a profitable business to earn a sufficient sum for the support of this little fleet. Still further, taking a received estimate putting the mercantile marine of the United States at forty millions of dollars, we find that it is only a little more than six times the annual cost of the Navy; so that this interest is protected at a charge of more than _fifteen per cent_ of its whole value! Protection at such price is not less ruinous than one of Pyrrhus's victories. [88] I refer to the pamphlet of S.E. Coues, "United States Navy: What is its Use?" It is to the Navy as an unnecessary arm of national defence, and part of the War establishment, that I confine my objection. So far as it is required for science, or for the _police_ of the seas,--to scour them of pirates, and, above all, to defeat the hateful traffic in human flesh,--it is a fit engine of Government, and cannot be obnoxious as a portion of the machinery of War. But, surely, a most costly navy to protect navigation in time of Peace against assaults from civilized nations is absurdly superfluous. The free cities of Hamburg and Bremen, survivors of the powerful Hanseatic League, with a commerce whitening the most distant seas, are without a single ship of war. Following this prudent example, the United States might be willing to abandon an institution already become a vain and expensive toy.
