BONTOC IGOROT, the name of a powerful, head-hunting tribe of the island of Luzon. The divisions of the tribe are po litical and exogamic; intensive agriculture is the means whereby subsistence is obtained as, owing to the hilly nature of the Bontoc territory, game is scarce. The language is somewhat complicated in structure and has a good vocabulary.
