(No. 7.)
Convention between the United States and Great Britain, signed at London, October 20th, 1818.
Article 2.—It is agreed that a line drawn from the most northwestern point of the Lake of the Woods, along the 49th parallel of north latitude, or, if the said point shall not be in the 49th parallel of north latitude, then that a line drawn from the said point due north or south, as the case may be, until the said line shall intersect the said parallel of north latitude, and from the point of such intersection due west along and, with the said parallel, shall be the line of demarkation between the territories of the United States and those of his Britannic majesty; and that the said line shall form the northern boundary of the said territories of the United States, and the southern boundary of the territories of his Britannic Majesty, from the Lake of the Woods to the Stony Mountains.
Art. 3.—It is agreed that any country that may be claimed by either party on the northwest coast of America, westward of the Stony Mountains, shall, together with its harbors, bays, and creeks, and the navigation of all rivers within the same, be free and open for the term of ten years from the date of the signature of the present convention, to the vessels, citizens, and subjects, of the two powers; it being well understood that this agreement is not to be construed to the prejudice of any claim which either of the two high contracting parties may have to any part of the said country, nor shall it be taken to affect the claims of any other power or state to any part of the said country; the only object of the high contracting parties, in that respect, being to prevent disputes and differences among themselves.
