one to five days or more. Dancing, singing, eating, and drinking mark the feast, and Isnegs wear their finest clothes. The shaman, Anituwan, prays to the spirit Gatan, before the first dog is sacrificed, if a human head had not been taken, and offered at the sacred tree, ammadingan. On the last day, a coconut is split in honor of the headhunter guardian, Anglabbang.The Pildap is an equivalent say-am but hosted by the poor. Conversion to Christianity grew after 1920, and today, the Isnegs are divided in their religious beliefs, with some still being animistic. Itneg/Tingguian The Itneg people, also known as Tingguian people, live in the mountainous area of Abra in northwestern Luzon who descended from immigrants from Kalinga, Apayao, and the Northern Kankana-ey. They are large in stature, have mongoloid eyes, aquiline nose, and are effective farmers. They refer to themselves as Itneg, though the Spaniards called them Tingguian when they came to the Philippines because they are mountain dwellers. The Tingguians are further divided into 11 distinct subgroups which are the Adasen, Balatok, Banao, Belwang, Binongan, Gobang, Inlaud, Mabaka, Maeng, Masadiit and Moyadan. Wealth and material possessions (such as Chinese jars, copper gongs called gangsa, beads, rice fields, and livestock) determine the social standing of a family or person, as well as the hosting of feasts and ceremonies. Despite the divide of social status, there is no sharp distinction between rich (baknang) and poor. Wealth is inherited but the society is open for social mobility of the citizens by virtue of hard work. Medium are the only distinct group in their society, but even then it is only during ceremonial periods. Kalinga The Kalingas are mainly found in Kalinga province which has an area of 3,282.58 sq. km. Some of them, however, already migrated to Mountain Province, Apayao, Cagayan, and Abra. As of 1995, they were counted to be 105,083, not including those who have migrated outside the Cordillera region. Kalinga territory includes floodplains of Tabuk, and Rizal, plus the Chico River. Gold and copper deposits are common in Pasil and Balbalan. Tabuk was settled in the 12th century, and from there other Kalinga settlements spread, practicing wet rice (papayaw) and swidden (uwa) cultivation. Kalinga houses (furoy, buloy, fuloy, phoyoy, biloy)are either octagonal for the wealthy, or square, and are elevated on posts (a few as high as 20–30 feet), with a single room. Other building include
