The provincial elected in 1629 is Fray Francisco de Herrera. Soon afterward dies Fray Bartolomé Martinez, of whom Aduarte writes a long biography; he ends his life in the Formosa mission, which he had established. The persecutions in Japan continue (1629-30), hundreds being martyred for the faith, and rigorous search being made everywhere for all Christians. It is with difficulty that any news of events there can be sent from that country. At the end of 1630, some Spaniards, accompanied by two Dominican friars, go on an embassy to the Chinese city of Ucheo; on the way, the Chinese crew mutiny, and kill most of the Spaniards. Four of these, including one of the friars, escape to the Chinese coast; the father remains there, and labors among the heathen. In December, 1633, the preaching of the gospel is introduced into Itui, in Luzón; two Dominican friars go thither, of whose mission, and of that region and its people, some account is given, followed by a long biography of Fray Tomás Gutierrez, head of the mission. The new provincial this year is Fray Domingo Gonçalez, Aduarte's editor; at this session of the chapter an important change is made, the abolition of the intermediate chapter. The missions are extended farther than ever before, but new workers are greatly needed. Many religious meet a martyr's death in Japan this year, and the persecution steadily increases in severity; biographical sketches of several martyrs are given, one of whom had achieved much in Formosa. In that island arises a rebellion among the natives, who murder (1633) one of the missionaries. Aduarte describes the mission to the Mandayas of northern Luzón, begun in 1631; it has been very successful, and many of those fierce and warlike people are now quite tamed and Christianized. The martyrdoms (in 1634) of several missionaries and Christian women in Japan, with sketches of their lives, are related. Two chapters are devoted to an account of the Dominican missions in China, which contain many devout Christians; at times, the missionaries are in danger of being slain by mobs. The Dominican mission in Formosa has not accomplished many conversions, and it has lost many devoted missionaries.
