There is perhaps no part of the exercise of the constitutional powers of the Federal Government which has given more general satisfaction to the people of the Union than this. The system has not been thus vigorously introduced and hitherto sustained to be now departed from or abandoned. In continuing to provide for the gradual increase of the Navy it may not be necessary or expedient to add for the present any more to the number of our ships; but should you deem it advisable to continue the yearly appropriation of $0.5 millions to the same objects, it may be profitably expended in a providing a supply of timber to be seasoned and other materials for future use in the construction of docks or in laying the foundations of a school for naval education, as to the wisdom of Congress either of those measures may appear to claim the preference. Of the small portions of this Navy engaged in actual service during the peace, squadrons have continued to be maintained in the Pacific Ocean, in the West India seas, and in the Mediterranean, to which has been added a small armament to cruise on the eastern coast of South America. In all they have afforded protection to our commerce, have contributed to make our country advantageously known to foreign nations, have honorably employed multitudes of our sea men in the service of their country, and have inured numbers of youths of the rising generation to lives of manly hardihood and of nautical experience and skill. The piracies with which the West India seas were for several years infested have been totally suppressed, but in the Mediterranean they have increased in a manner afflictive to other nations, and but for the continued presence of our squadron would probably have been distressing to our own. The war which has unfortunately broken out between the Republic of Buenos Ayres and the Brazilian Government has given rise to very great irregularities among the naval officers of the latter, by whom principles in relation to blockades and to neutral navigation have been brought forward to which we can not subscribe and which our own commanders have found it necessary to resist. From the friendly disposition toward the United States constantly manifested by the Emperor of Brazil, and the very useful and friendly commercial intercourse between the United States and his dominions, we have reason to believe that the just reparation demanded for the injuries sustained by several of our citizens from some of his officers will not be withheld. Abstracts from the recent dispatches of the commanders of our several squadrons are communicated with the report of the Secretary of the Navy to Congress.
