Should they seem flying too high as if to pass, the blacks would throw the pieces of bark high in the air, imitating, as they did so, the cry of hawks.

Down the ducks would fly turning back; some of the men would whistle like ducks, others would throw bark again, giving the hawk's cry, which would frighten the birds, making them double back into the net, where they were quickly despatched by those waiting.
Murrahgul is another trap.

This is a yard made all round a waterhole with one opening; about this opening they will fasten, from stumps or logs, strong strings with a slipping knot.

The game, emu or kangaroo, would probably step into one of these string nooses, would try to pull its leg out; the harder it pulled the tighter the knot.

Or the blacks might have put a sort of cross-bar overhead at the entrance, with hanging strings having a slip knot; in would go an emu's head, the bird would rush on and be strangled.
Boobeen is a primitive cornet, a hollowed piece of Bibbil wood, one end partially filled up with pine gum, and ornamented outside with carvings.
