Representative image. A pair of bamboo snorrebot bull-roarers from island Southeast Asia, one painted blue, joined by a long cord; the Iban (Sea Dayak) bull-roarer of Sarawak's rivers, sometimes hung as a boys' toy from a cross-piece left standing when jungle was cleared for padi, has not been photographed.

When a patch of Borneo jungle was cleared for padi, a few trees were left standing on high ground so as not to offend the Toh, the spirits of the locality, who were vaguely supposed to use the trees as resting-places. Such a tree might be stripped of its branches, a pole lashed across the stem and hung with bunches of palm leaves, and onto this cross-piece a boys' bull-roarer was sometimes hung to dangle and flicker in the breeze. Hose and McDougall, who recorded the custom, place it among the Kayan and note in a footnote that they knew of no other use of the bull-roarer by any of the tribes; the Sea Dayak label here is the catalogue's inference, not the source's.

a "bull-roarer," which is used by boys as a toy, is sometimes hung upon such a cross-piece to dangle and flicker in the breeze.
