In the month of December last 121 African negroes were landed at Key West from a Spanish slave-trading vessel stranded within the jurisdiction of the United States while pursued by an armed schooner in His Britannic Majesty's service. The collector of the customs at Key West took possession of these persons, who were afterwards delivered over to the marshal of the Territory of East Florida, by whom they were conveyed to St. Augustine, where they still remain. Believing that the circumstances under which they have been cast upon the compassion of the country are not embraced by the provisions of the act of Congress of 3d March, 1819, or of the other acts prohibiting the slave trade, I submit to the consideration of Congress the expediency of a supplementary act directing and authorizing such measures as may be necessary for removing them from the territory of the United States and for fulfilling toward them the obligations of humanity. John Quincy Adams. Washington, _May 1, 1828_. _To the Senate of the United States_: In compliance with a resolution of the Senate of the 17th ultimo, relating to the removal of the Indian agency from Fort Wayne, in the State of Indiana, I transmit a report from the Secretary of War, with the documents and information requested by the resolution. John Quincy Adams. Washington, _May 5, 1828_. _To the Senate of the United States_: In compliance with a resolution of the Senate of the 30th ultimo, requesting information concerning any regulation of the Government of Brazil relative to the reduction of certain duties, I transmit herewith a report from the Secretary of State, exhibiting the information received at that Department on the subject. John Quincy Adams. Washington, _May 5,1828_. _To the Senate of the United States_: I communicate to the Senate, for their consideration and advice, a treaty of commerce and navigation between the United States and His Majesty the King of Prussia, signed on the 1st instant at this place by the Secretary of State and the chargé d'affaires of Prussia residing here. A copy of the treaty is also transmitted. John Quincy Adams.
