The principal topics treated in this volume (1636 37) are the commerce of the Philippine Islands (especially with Nueva España) and the punishment inflicted by Corcuera on the Moro pirates of Mindanao. The former is fully discussed by Juan Grau y Monfalcón, procurator of Filipinas at the Spanish court; the latter is related in various documents, written mainly by participants in the Mindanao campaign. Certain minor documents relate to the administration of the islands and to the religious orders there.
