During the period between the Ten Years' War and the final War of Independence there was a succession of Governors-General, varying chiefly in the degree of their unacceptability to the Cuban people and of the ineptitude with which they maladministered the affairs of the island and thus contributed to the ultimate and inevitable catastrophe. Martinez Campos served, with the best of intentions, until the late summer of 1883. Then on September 28 he was succeeded by Ignacio Maria del Castillo. His administration endured for three years, and was replaced in 1886 by that of General Emilio Calleja y Isasi, who gave place the next year to Saba Marin. Another change occurred on March 13, 1889, when Manuel de Salamanca y Negrete took office. He served for less than a year, being succeeded on February 7, 1890, by General J. Chinchilla. To the latter must be accorded the distinction of having the shortest term of all, for on June 10 following his place was taken by General Polavieja. He served for two years and was succeeded on May 31, 1892, by General A. R. Arias, who in turn, on August 10, 1894, was replaced by General Emilio Calleja, who thus entered upon his second term, in which he was to suffer the penalty of the misdeeds of a long line of predecessors, and was to begin reaping the whirlwind harvest of the evil wind which for four centuries Spain had been sowing with a perverse and ruthless hand. CHAPTER XVIII "New occasions," sang a great American poet of freedom and of progress, "new occasions teach new duties"; and splendidly was the truth exemplified in Cuba in the era of which we have been writing in this volume. There befell the island at the beginning of the Nineteenth Century a new occasion, the greatest thus far in all its history since the landfall of Columbus. It was perhaps only partially realized at first, and it took many years for the complete realization to dawn upon the universal popular mind. But even before the realization came, the Cuban people, not yet cognizant of the tremendous force which was working within them, began to rise to meet the new occasion, the new opportunity which was opening before them, with a triumphant spiritual puissance which has not often been rivalled in the annals of the nations. [Illustration: FELIPE POEY] FELIPE POEY One of Cuba's greatest natural scientists, Felipe Poey, was born in Havana on May 26, 1799, and was educated at the San Carlos Seminary and in France. He became a lawyer in Madrid, but in 1822 left that city because of political conditions and returned to Cuba to devote himself to ichthyology and entomology. He published a monumental work on "Cuban Ichthyology," and others on "Cuban Lepidopteres," "Cuban Mineralogy," the "Geography of Cuba," and the "Natural History of Cuba." He was for many years professor of zoology at the University of Havana and Dean of the Faculty of Sciences. He died in 1891.
