The present condition of the defenses of our principal seaports and navy-yards, as represented by the accompanying report of the Secretary of War, calls for the early and serious attention of Congress; and, as connecting itself intimately with this subject, I can not recommend too strongly to your consideration the plan submitted by that officer for the organization of the militia of the United States. In conformity with the expressed wishes of Congress, an attempt was made in the spring to terminate the Florida war by negotiation. It is to be regretted that these humane intentions should have been frustrated and that the effort to bring these unhappy difficulties to a satisfactory conclusion should have failed; but after entering into solemn engagements with the commanding general, the Indians, without any provocation, recommenced their acts of treachery and murder. The renewal of hostilities in that Territory renders it necessary that I should recommend to your favorable consideration the plan which will be submitted to you by the Secretary of War, in order to enable that Department to conduct them to a successful issue. Having had an opportunity of personally inspecting a portion of the troops during the last summer, it gives me pleasure to bear testimony to the success of the effort to improve their discipline by keeping them together in as large bodies as the nature of our service will permit. I recommend, therefore, that commodious and permanent barracks be constructed at the several posts designated by the Secretary of War. Notwithstanding the high state of their discipline and excellent police, the evils resulting to the service from the deficiency of company officers were very apparent, and I recommend that the staff officers be permanently separated from the line. The Navy has been usefully and honorably employed in protecting the rights and property of our citizens wherever the condition of affairs seemed to require its presence. With the exception of one instance, where an outrage, accompanied by murder, was committed on a vessel of the United States while engaged in a lawful commerce, nothing is known to have occurred to impede or molest the enterprise of our citizens on that element, where it is so signally displayed. On learning this daring act of piracy, Commodore Reed proceeded immediately to the spot, and receiving no satisfaction, either in the surrender of the murderers or the restoration of the plundered property, inflicted severe and merited chastisement on the barbarians. It will be seen by the report of the Secretary of the Navy respecting the disposition of our ships of war that it has been deemed necessary to station a competent force on the coast of Africa to prevent a fraudulent use of our flag by foreigners.
