Note 1 — Chapter I · The Igorot Culture Group Igorot land

The second type of surface is the coastal hill area. It extends from the coastal plain irregularly back to the mountains, and is thought to be much narrower on the eastern coast than on the western—in fact, it may be quite absent on the eastern. It is the remains of a tilted plain sloping seaward from an altitude of about 1,000 feet to one of, say, 100 feet, and its hilly nature is due to erosion. These hills are generally covered only with grasses; the sheltered moister places often produce rank growths of tall, coarse cogon grass.1 The soil varies from dark clay loam through the sandy loams to quite extensive deposits of coarse gravel. The level stretches in the hills on the west coast are generally in the possession of the Christian peoples, though here and there are small pueblos of the large Igorot group. The Igorot in these pueblos are undergoing transformation, and quite generally wear clothing similar to that of the Ilokano.
