3. This gave a great impulse to the naval tendencies of the nation, and it soon became the settled determination of the people to supersede England as the strongest naval power. She had been _Mistress_ of the Seas; there were strong reasons for our ambition to become _Masters_, at least in American waters. We had an extensive line of coast, and our “Monroe Doctrine,” that Americans ought to rule America, and that European governments should never be permitted to acquire a preponderating influence in North America, rendered a strong navy important. Our people, however, are so largely commercial that skillful mariners are always at command; and the government has never maintained, in time of peace, a very large naval force. 4. What they can do in time of need was demonstrated during the Civil War, when the navy was increased in two years by more than 400 vessels—many of them very expensive and powerful; proving in actual conflict the inability of the strongest land fortresses to resist them. The thousands of miles of the Atlantic and Gulf coast blockade, that was rendered so effective as to _smother_ the Confederate government, so to speak, destroying its finances by rendering its cotton unavailable, is the best comment on the naval resources of the United States. The extreme boldness and vigor with which the Confederate cruisers that managed to escape the blockade fell on our merchant vessels, and laid waste our commerce, is another point in the argument; for they were Americans, and demonstrated the natural prowess of Americans on the sea, of which we could well be proud but that it did fatal harm to our mercantile marine. 5. Not half of the vessels belonging to the navy are, however, now (in time of peace) in commission—that is, in active service. The rest are either laid up, or in process of repair. Most of those in commission are employed in what is called squadron service. The Secretary of the Navy in a late report enumerates seven of these squadrons; viz.: the European, the Asiatic, the North Atlantic, the South Atlantic, the North Pacific, the South Pacific, and the Gulf squadrons. The names given to these squadrons indicate their whereabouts, and their cruising grounds. These squadrons consist of six, eight, ten, twelve or fifteen vessels, as the work to be done may require. It is their duty to visit the seaports of the various countries along the coasts of which they cruise, in order to protect our merchantmen against pirates or enemies of any description, which may molest them or interfere with their rights and privileges; and also to look after the interests and dignity of the United States.
