To the Senate of the United States:

In the message to both Houses of Congress at the commencement of their present session it was intimated that the commission for liquidating the claims of our fellow-citizens to indemnity for slaves and other property carried away after the close of the late war with Great Britain in contravention to the first article of the treaty of Ghent had been sitting in this city with doubtful prospects of success, but that propositions had recently passed between the two Governments which it was hoped would lead to a satisfactory adjustment of that controversy.

I now transmit to the Senate, for their constitutional consideration and advice, a convention signed at London by the plenipotentiaries of the two Governments on the 13th of the last month, relating to this object. A copy of the convention is at the same time sent, together with a copy of the instructions under which it was negotiated and the correspondence relating to it. To avoid all delay these documents are now transmitted, consisting chiefly of original papers, the return of which is requested.

JOHN QUINCY ADAMS.
