To the Senate of the United States:
I lay before you the convention signed on the 12th day of May last between the United States and Great Britain for settling their boundaries in the northeastern and northwestern parts of the United States, which was mentioned in my general message of the 17th instant, together with such papers relating thereto as may enable you to determine whether you will advise and consent to its ratification.
TH: JEFFERSON.
