Note 1 — The Ilongot or Ibilao of Luzon

The grewsome practise of taking human heads is particularly associated with the Igorot peoples of the Cordillera of Luzon. These all engage in it or have done so until recently. But to-day the most persistent and dreaded headhunters are neither Igorot nor inhabitants of the Cordillera; they are a wild, forest-dwelling people in the broken and almost impenetrable mountain region formed by the junction of the Sierra Madre range with the Caraballo Sur. They have been called by different names by the peoples contiguous to them on the north, west and south, “Italon,” “Ibilao,” “Ilongot” or “Ilūngūt.” The last designation would for some reasons be the preferred, but “Ibilao,” or as it is quite commonly pronounced locally through northern Nueva Ecija, “Abilao,” has perhaps the widest use.1
