built without the expectation of using them for many years, due to the shifting nature of agricultural work. Houses are built as close as possible to a new field. Occasionally, a site is found so favorable that the house is built to last, employing heavy and solid wooden supports. The strongest houses would have supporting beams made of hardwood 15 to 20 centimeters thick, but this is rather rare. Usually, the supporting timbers are 1 centimeter thick, the entire structure being so light a person could easily shake it at one of the supports. Tops of supporting beams are connected with rough logs which serve as stringers, to which the split bamboo, or palma brava, or other flooring materials are lashed with rattan strips. No nails are used in putting houses together, and even the use of wooden pegs is rare. Strips of rattan are the most favored fastening material. The interior of the house contains both the sleeping area and the hearth. The latter found near the door, ordinarily consists of a shallow, wooden squarish structure whose bottom is covered with a thick layer of earth or ash. Large stones are put atop the ashes to hold the earthenware pots. On the walls of the house, water containers of bamboo about 1–2 meters long are propped up. The small granaries, built near the Subanon house, are raised some meters above the ground, and at times are so high a notched log is required to enter the structure. Inside the granary, the rice is stored either in baskets or in bags. Aside from these granaries and their dwellings, there is a special structure added to the spirit house of a shaman—a miniature house called , which is made to hang from under the eaves. The is where the sacred dishes are kept. On the roof of the spirit house stand carved wooden images of the omen bird . Visual arts and crafts Unlike the glazed imported jars in some households, the indigenous earthenware of the Subanon are simpler in execution and design. Every household has at least one woman who is knowledgeable in the art of pottery, and who turns out jars as required by domestic needs. The process of making pots starts with the beating of clay on a wooden board with a wooden pestle. The clay is then shaped into a ball, on top of which a hole
