A dispute between Nicaragua and Costa Rica, as to the eastern extremity of their boundary line, was decided by General Alexander, a referee accepted by the two republics. The boundary had not been well defined in a treaty negotiated for its settlement in 1858. According to the terms of the treaty, the line was to start from the Atlantic at the mouth of the San Juan river; but changes of current and accumulation of river drift, etc., gave ground for dispute as to where the river actually made its exit. President Cleveland in 1888, acting as arbitrator at the request of the two countries, decided that the treaty of 1858 was valid, but was not clear as to which outlet of the delta was the boundary. Finally, in 1896, an agreement was reached for a final survey and marking of the boundary line, and President Cleveland, on request, appointed General Alexander as arbitrator in any case of disagreement between the surveying commissions. The decision gives to Nicaragua the territory upon which Greytown is situated, and practical control of the mouth of the canal. CENTRAL AMERICA, Guatemala: A. D. 1897-1898. Dictatorship of President Barrios. His assassination. In June, 1897, President José M. Reyna Barrios, whose six years term in the presidency would expire the next March, fearing defeat in the approaching election, forcibly dissolved the National Assembly and proclaimed a dictatorship. Three months later a revolt was organized by General Prospero Morales; but Barrios crushed it with merciless energy, and a veritable reign of terror ensued. In February, 1898, the career of the Dictator was cut short by an assassin, who shot him to avenge the death of a wealthy citizen, Don Juan Aparicio, whom Barrios had executed for expressing sympathy with the objects of the rebellion of the previous year. Control of the government was then taken by Dr. Cabrera, who had been at the head of the party which supported Barrios. A rising under Morales was again attempted, but failed. Morales, in a dying condition at the time, was betrayed and captured. Cabrera, with no more opposition, was elected President for six years. CENTRAL AMERICA, Nicaragua—Costa Rica: A. D. 1900.
