Rice-hull coals.
Placed in a depression over which a cane mat, ātag, is placed to produce warmth in sleeping. Corn is sprinkled into glowing hulls for popping. Placed at the edge of an upland field where mung beans, balātung, or kidney beans, buddīlah, are planted to drive away weevils, dāngaw, attacking these crops, by allowing the dense smoke to blow over the plants. Made by piling hulls, covering the pile with ashes followed by rice straw. The pile is then burned. Within an hour the pile all ignites and glows.
