Spanish authorities in giving titles as captains and lieutenants to Christians makes such persons the real datos of the island and weakens the hereditary allegiance. The remnants of the Moros about Dávao ask for villages, but it is only pretense, in order that they may continue to live under their old customs, and so that the datos may not lose the few followers left to them. It is advised that the people be encouraged to desert their datos and panditas, and that all the Moros be assembled into one village. The many small villages of the Moros, each with its dato and pandita, are an obstacle to the reduction and conversion of the heathens. The letter written by Father Pablo Cavalleria to Father Francisco Sanchez from Isabela de Basílan in the island of Basílan, December 31, 1886, gives a great deal of most important information regarding the Moros of that island. The native race is evidently fewer in number than the Moros (who number ten or twelve thousand), and is partially christianized. The Moros inhabit the coast and the interior, the former being known as Sámal Laút, who are fishermen, and the latter as Yacans, who are agriculturists. They are hostile to each other. With the Sámal Laút are mingled also Joloans and Malays. Personal descriptions of the Moros, their mental characteristics, their religion, marriage and mortuary customs, etc., are given. Their chief feast is the celebration of the birth of Mahomet, though that date is not fixed but depends rather on when there is sufficient food for a good feast. They are superstitious, and perform various superstitious rites. They have seven heavens and seven hells, each with its distinctive signification. Their method of fighting is described. Their hatred toward the Christians is well shown in a native song quoted by Father Cavalleria.
