After unavailing attempts to reach an understanding through a Joint High Commission, followed by prolonged negotiations, conducted in an amicable spirit, a convention between the United States and Great Britain was signed, January 24, 1903, providing for an examination of the subject by a mixed tribunal of six members, three on a side, with a view to its final disposition. Ratifications were exchanged on March 3 last, whereupon the two governments appointed their respective members. Those on behalf of the United States were Elihu Root, Secretary of War; Henry Cabot Lodge, a Senator of the United States, and George Turner, an ex-Senator of the United States, while Great Britain named the Right Honorable Lord Alverstone, Lord Chief Justice of England; Sir Louis Amable Jetté, K.C.M.G., retired judge of the Supreme Court of Quebec, and A. B. Aylesworth, K.C., of Toronto. This Tribunal met in London on September 3, under the Presidency of Lord Alverstone. The proceedings were expeditious, and marked by a friendly and conscientious spirit. The respective cases, counter cases, and arguments presented the issues clearly and fully. On the 20th of October a majority of the Tribunal reached and signed an agreement on all the questions submitted by the terms of the Convention. By this award the right of the United States to the control of a continuous strip or border of the mainland shore, skirting all the tide-water inlets and sinuosities of the coast, is confirmed; the entrance to Portland Canal (concerning which legitimate doubt appeared) is defined as passing by Tongass Inlet and to the northwestward of Wales and Pearse Islands; a line is drawn from the head of Portland Canal to the fifty-sixth degree of north latitude; and the interior border line of the strip is fixed by lines connecting certain mountain summits lying between Portland Canal and Mount St. Elias, and running along the crest of the divide separating the coast slope from the inland watershed at the only part of the frontier where the drainage ridge approaches the coast within the distance of ten marine leagues stipulated by the treaty as the extreme width of the strip around the heads of Lynn Canal and its branches. While the line so traced follows the provisional demarcation of 1878 at the crossing of the Stikine River, and that of 1899 at the summits of the White and Chilkoot passes, it runs much further inland from the Klehini than the temporary line of the later _modus vivendi_, and leaves the entire mining district of the Porcupine River and Glacier Creek within the jurisdiction of the United States.
