Several are wrapped around a pile of newly harvested rice to protect it from chickens and other animals before it is stored inside the granary; 2) Atag an olo'an `sleeping mat'. Mats are rolled and stored in the house during the day and brought out at night for sleeping; 3) Atag di palan `ceiling mat'. This mat is spread out on the ceiling rafters, dālag.
