It seems desirable, at the outset, to set forth certain general conclusions regarding the Tinguian and their neighbors. Probably no pagan tribe of the Philippines has received more frequent notice in literature, or has been the subject of more theories regarding its origin, despite the fact that information concerning it has been exceedingly scanty, and careful observations on the language and physical types have been totally lacking. According to various writers, these people are descended from Chinese, Japanese, or Arabs; are typical Malay; are identical with the Igorot; are pacific, hospitable, and industrious; are inveterate head-hunters, inhospitable, lazy, and dirty. The detailed discussion of these assertions will follow later in the volume, but at this point I wish to state briefly the racial and cultural situation, as I believe it to exist in northwestern Luzon.
