Bin-ga (bailer shell)
In a country where there is no fresh running water, finding and carrying water was essential. Most inland sources of water had to be dug out. The strong and curvaceous structure of the bin-ga (bailer shell) was perfect for carrying freshwater, and for digging out muddy soaks. Finding soaks and jila is a skilled art, but the tell-tale signs of bin-ga fragments are proof of the existence of water. Bin-ga were traded across the desert and their fragments are still found around old water holes.
