A great draught dried up all the rivers. The old men suggested digging in a river bed to find the soul of the river. After three days of digging, a great spring gushed forth, but while the Ifugaos celebrated, a storm came, the river kept rising, and the elders advised people to run for the mountains. Only two people made it to safety, a brother and sister, on seperate mountains. After six months, the waters receded. The sister later found herself with child and ran away in shame, but the god Maknongan assured her that her shame had no foundation. [Demitrio, in Dundes]
