The troops intended to occupy a station at the mouth of the St. Peters, on the Mississippi, have established themselves there, and those who were ordered to the mouth of the Yellow Stone, on the Missouri, have ascended that river to the Council Bluff, where they will remain until the next spring, when they will proceed to the place of their destination. I have the satisfaction to state that this measure has been executed in amity with the Indian tribes, and that it promises to produce, in regard to them, all the advantages which were contemplated by it. Much progress has likewise been made in the construction of ships of war and in the collection of timber and other materials for shipbuilding. It is not doubted that our Navy will soon be augmented to the number and placed in all respects on the footing provided for by law. The Board, consisting of engineers and naval officers, have not yet made their final report of sites for two naval depots, as instructed according to the resolutions of March 18 and April 20, 1818, but they have examined the coast therein designated, and their report is expected in the next month. For the protection of our commerce in the Mediterranean, along the southern Atlantic coast, in the Pacific and Indian oceans, it has been found necessary to maintain a strong naval force, which it seems proper for the present to continue. There is much reason to believe that if any portion of the squadron heretofore stationed in the Mediterranean should be withdrawn our intercourse with the powers bordering on that sea would be much interrupted, if not altogether destroyed. Such, too, has been the growth of a spirit of piracy in the other quarters mentioned, by adventurers from every country, in abuse of the friendly flags which they have assumed, that not to protect our commerce there would be to abandon it as a prey to their rapacity. Due attention has likewise been paid to the suppression of the slave trade, in compliance with a law of the last session. Orders have been given to the commanders of all our public ships to seize all vessels navigated under our flag engaged in that trade, and to bring them in to be proceeded against in the manner prescribed by that law. It is hoped that these vigorous measures, supported by like acts by other nations, will soon terminate a commerce so disgraceful to the civilized world. In the execution of the duty imposed by these acts, and of a high trust connected with it, it is with deep regret I have to state the loss which has been sustained by the death of Commodore Perry. His gallantry in a brilliant exploit in the late war added to the renown of his country. His death is deplored as a national misfortune. JAMES MONROE. SPECIAL MESSAGES.
