All the provisions of the third article of the convention concluded between the United States of America and his majesty the king of the United Kingdom of Great Britain and Ireland, on the 20th of October, 1818, shall be, and they are hereby, further indefinitely extended and continued in force, in the same manner as if all the provisions of the said article were herein specifically recited.

DOCUMENT C _Statement concerning merger of Hudson's Bay Company and North-West Company; and grant to Hudson's Bay Company of 1821 and 1838 to trade in the Oregon Country._ A great enmity arose between the Hudson's Bay Company and the North-West Company. In 1815 a regular war broke out between the two companies, which was, for some time after, openly carried on. In 1821 a compromise was effected, by which the North-West Company became united with, or rather merged, in the Hudson's Bay Company. In connection with this merger the British Parliament July 2, 1821, passed an act entitled, "An act for regulating the fur trade and establishing a criminal and civil jurisdiction in certain parts of North America," containing every provision required to give stability to the Hudson's Bay Company, and efficiency to its operation. Under this act of Parliament, the King was authorized to make grants or give licenses for the exclusive privilege of trading with the Indians in all such parts of North America, not being parts of the territories previously granted to the Hudson's Bay Company, or of any of His Majesty's provinces in North America, or of any territories belonging to the United States of America; "provided, however, that no such grant or license shall be given for a longer period than twenty-one years; that no grant or license for exclusive trade, in the part of America west of the Rocky mountains, which, by the convention of 1818 with the United States, remained free and open to the subjects or citizens of both nations, shall be used to the prejudice or exclusion of citizens of the United States engaged in such trade; and that no British subject shall trade in those territories west of the Rocky mountains without such license or grant."
