ARGENTINE REPUBLIC: A. D. 1898. Settlement of boundary dispute with Chile. Election of President. "A long unsettled dispute as to the extended boundary between the Argentine Republic and Chile, stretching along the Andean crests from the southern border of the Atacama Desert to Magellan Straits, nearly a third of the length of the South American continent, assumed an acute stage in the early part of the year, and afforded to this Government occasion to express the hope that the resort to arbitration, already contemplated by existing conventions between the parties, might prevail despite the grave difficulties arising in its application. I am happy to say that arrangements to this end have been perfected, the questions of fact upon which the respective commissioners were unable to agree being in course of reference to Her Britannic Majesty for determination. A residual difference touching the northern boundary line across the Atacama Desert, for which existing treaties provided no adequate adjustment, bids fair to be settled in like manner by a joint commission, upon which the United States Minister at Buenos Aires has been invited to serve as umpire in the last resort." _Message of the President of the United States of America, December, 1898._ The arbitration of the United States Minister, Honorable William I. Buchanan, proved successful in the matter last referred to, and the Atacama boundary was quickly determined. In June, 1898, General Julio Roca was elected President and assumed the office in October. In July a treaty of arbitration was concluded with the government of Italy, which provides that there shall be no appeal from the decision of the arbitrators. ----------ARGENTINE REPUBLIC: End-------- ARGON, The Discovery of.
