From the point where the 45th parallel intersected the St. Lawrence, the line was, under the Treaty of 1783, to be carried up the middle of the rivers and lakes to the water communication between Lake Huron and Lake Superior, with the necessary result that Lake Michigan was entirely excluded from Canada. By the Sixth Article of the Treaty of Ghent two Commissioners were to be appointed to settle doubts as to what was the middle of the waterway and to which of the two nations the various Islands belonged: and, as in other cases, if the Commissioners disagreed, they were to report to their respective governments with a view to arbitration by a neutral power. A joint award was given,[237] signed at Utica on the 18th of June, 1822, the boundary being elaborately specified and the report being accompanied by a series of maps. [Sidenote: The line between Lake Huron and Lake Superior, and to the most North-Western point of the Lake of the Woods.] [Sidenote: Nonexistence of the ‘Long Lake’.] [Sidenote: The ‘most North-Western point of the Lake of the Woods’ determined.] [Sidenote: The Ashburton Treaty and the Treaty of 1871.] [Sidenote: Navigation of the St. Lawrence.] The Treaty of 1783 laid down that the line was to be drawn, as already stated, through the middle of Lake Huron ‘to the water-communication between that lake and Lake Superior; thence through Lake Superior, Northward of the Isles Royal and Phelipeaux to the Long Lake; thence through the middle of said Long Lake and the water communication between it and the Lake of the Woods to the said Lake of the Woods, thence through the said lake to the most North-Western point thereof’. Under the Sixth Article of the Treaty of Ghent the Commissioners defined the frontier line well into the strait between Lakes Huron and Superior, but stopped short of the Sault St. Marie, at a point above St. Joseph’s Island and below St. George’s or Sugar Island. Here they considered that their labours under the Sixth Article terminated. But the next Article of the Treaty of Ghent provided that the same two Commissioners should go on to determine ‘that part of the boundary between the dominions of the two powers, which extends from the water communication between Lake Huron and Lake Superior to the most North-Western point of the Lake of the Woods’.
