Source term: bullroarer; humming board

irumbu: a spectre whose voice, like the lion's, the bullroarer made to quiet a crying child.

On Kilimanjaro, Chagga mothers kept their children in line with bogeys. A baby who would not eat its evening soup heard its elder brother outside, making the noise of a koko; the bananas in the attic, the mother said, were guarded by an animal with a prickly tail. When she wanted a child to stop crying, a bullroarer gave voice to a lion, or to the irumbu spectre. Children made humming boards of their own, scraped thin and swung on banana-bast string. The little ones feared the noise, like a great bird beating its wings, and it was heard most at the beginning of the greater rains.

If she wants her child to stop crying, the voice of a lion or the irumbu-spectre is produced with a bullroarer.
