By the 6 article of the Convention between Great Britain
and and
Russia dated
St. Peter[s]burgh 16/28 February 1825, it is
provided—
That the subjects of His Britanic Majesty, from whatever
quarter they may arrive, whether from the Ocean or from the
interior of the Continent, shall for ever enjoy the right of
navigating freely and without any hindrance whatever, all the
rivers and streams which in their course towards the Pacific
Ocean may cross the line of demarcation upon the line of Coast
described in Article III of the present Convention,
and the Company presume that there can be no doubt that this
Article is binding on the
United United States as the present possessor
of the Territory.
