as he can, the pirates of that group to peaceful agriculturists, and secure from them the payment of tribute. Next, he is to go on a similar errand to Mindanao; and, as many of its inhabitants are Mahometans, he must strive to uproot "that accursed doctrine" there. Sande returns to Manila, whence in the following year (February 28, 1579) he despatches Juan Arce de Sadornil with a fleet to Borneo, giving him detailed instructions for his conduct on this expedition. He is to ascertain the condition of affairs there, and gently endeavor to gain the submission of the king as a vassal of Spain. Sadornil goes to Borneo, and conducts various negotiations with the king, but cannot induce the latter to confer with him in person. Finally, seeing that he can accomplish nothing, and that his men are suffering from confinement and illness, he decides to return to Manila; and he advises Sande that a settlement of Spaniards in Borneo must, to be successful, be made in the town where the Moro court resides. In June, 1578, the king of Sulu submits to the Spanish power. From the Moluccas comes the news that the people of Ternate have revolted against the Portuguese, who have been compelled to abandon their fortress there and retreat to Amboina. Their trade in spices is therefore greatly injured, for the time; and other Malayan peoples are also hostile to the Portuguese. Sande again sends (January, 1579) an expedition to Mindanao and Sulu, under Captain de Ribera, to secure their submission to Spanish authority. His instructions lay special stress on proper care for the health of the troops. The tribute desired from Sulu consists of "two or three tame elephants." Ribera goes to the Rio Grande of Mindanao, but can accomplish nothing; for the natives, in terror of the Spaniards, have abandoned their villages, fleeing to the mountains. Ribera erects a fort at the delta of the river, and receives the submission of a few neighboring chiefs; but, as his men are being prostrated by sickness, he obtains from a friendly _dato_ (chief) a list of the Indian villages and their population, with such information as he can gather, and departs--sending a small detachment of troops to pacify the district of Butuan. Going to Cavite, Ribera finds there a deputation from Sulu, who bring a little tribute saying that their people have been harassed by famine ever since Figueroa came, a year before, to demand tribute from them. Finding upon investigation that this story is true, he gives back their tributes, receiving instead a cannon which they had taken from a wrecked Portuguese galley. Ribera then returns to Cebu.
