The Jesuit Juan de Barrios, who accompanied Corcuera in his expedition against Jolo, relates (March-April, 1638) the events of that campaign in letters to Manila. The Spaniards are repulsed several times in attacking the Moro stronghold, and one of their divisions is surprised by the enemy with considerable loss to the Spaniards. Corcuera then surrounds the hill with troops and fortifications, and begins a regular siege of the Moro fort; various incidents of this siege are narrated. On the day after Easter the Moros, starved and sick, send Corcuera proposals for surrender; and finally they abandon their stronghold, and take flight, leaving the Spaniards in possession of all their property as well as the fort. A letter from Zamboanga (perhaps by Barrios) adds further particulars of the surrender and flight of the Joloans, the mortality among the Spaniards, the garrison left there by Corcuera, etc. Taking up the general religious status of the islands, we select from the _Recopilacion de las leyes de Indias_, lib. i, tit. xiv, the laws that especially concern the religious in the Philippines, dated from 1585 to 1640. These persons may not go to China or other countries, or return to Spain or Mexico, without special permission from the civil and ecclesiastical authorities. Carmelites may go to the islands from Mexico. The missions must be so assigned that each order has its own territory, separate from the others. The usual supplies shall be given to such religious as obtain permission to enter China and Japan; and all royal officials are directed to aid the fathers in their journeys, and not to hinder them. Religious who lead scandalous lives, or have been expelled from their orders, may not remain in Filipinas. The papal decrees _de alternativa_ are to be enforced in the Indias. The restrictions imposed on religious going to the Japan missions are removed; all orders may go, but are charged to set an example of harmony and fraternal behavior. The missionaries are forbidden to engage in commerce or other business; the field shall be suitably divided among the various orders; and any bishops who may be appointed in Japan shall be suffragan to the see of Manila. Clerics from Eastern India are not to be allowed to perform priestly functions in Filipinas, or even to enter the islands. The proceeds resulting from the sale of the bulls of the Crusade must be placed in the royal treasury, and not used in trade by the treasurers of the Crusade. The Jesuit Colin places at the end of his _Labor evangelica_ (Madrid, 1663) a statement--prepared, he says, in accordance with a command from the king--of the number of missions, houses, and laborers supported by that order in the Philippines, a survey of its field and labors in the year 1656. He describes the scope, functions, and resources of the colleges in Manila; the missions near that city; and, in their order, the residences and missions maintained by the Society in the respective islands.
