He was succeeded by the Vice-President Uriburu, who had also been chosen on account of his neutrality; but he was more successful, and he had the powerful support of Roca and Pellegrini. During his first year of office it seemed probable that a foreign war would be added to all the other troubles of the Republic, for the boundary dispute with Chile was assuming a threatening attitude and continued to disturb public tranquillity for seven years. This subject can be treated more conveniently in the history of the next administration, when it was settled. In this year a boundary dispute with Brazil about the Misiones was settled by the arbitration of President Cleveland in favour of the latter country.[54] Little progress in settling the nation's difficulties was made under Uriburu, but internal and external peace was maintained. In 1898 General Roca succeeded him as President, and it was generally felt that a man had appeared who was competent to steer the ship of State into smoother waters. He had been of great service during the troubles which had attended the resignation of Celman, and had kept the disorderly elements in check. He had, all through the troubles of ten years, been on the side of law and order, and he was practically the leader of a national party. In May, 1898, the President in his message to Congress denounced judicial corruption, and the publicity which he gave to these abuses resulted in several improvements; but there is still much matter for adverse criticism in the administration of justice in Argentina. The improvements in Government methods led to gradual general improvement, which, however, was also the result of natural causes, and Argentina became undoubtedly the most prosperous country in South America. The fear of political disintegration has become a thing of the past, owing to the preponderance of the capital in wealth and influence, but neither Roca himself nor any other successor has been able to banish a serious evil from which Argentina suffers, and which, though not causing civil war on a large scale, brings about disquieting strikes and riots. This is due to defective methods of government. The President may be said to have been the "saviour of his country" in the sense that a weaker or dishonest man would probably have plunged the country into both domestic and foreign war, and neutralised all the progress of a generation. But he could not bequeath political capacity to his colleagues, nor could he eradicate many bad traditions of long standing.
