Wagner was essentially the exponent of folk-lore music, wherein must be expressed the fundamentals of human passion unrefined.
The most celebrated weapon is probably the boomerang the most celebrated kind to whites, though not most useful to blacks, is the Bubberab, or returning boomerang.

These are made chiefly of Gidya and Myall.

Here these 'Come backs' are never carved, are more curved than the ordinary boomerang, and were greased, rubbed with charred grass, and warmed before being used, so that the slightest warp would be straightened.

It is marvellous the accuracy with which an adept can throw one of these weapons, locating it on the exact place to which he wishes it to return.
Gidya is the favourite wood for boomerangs.

They are first roughly shaped, then thrown into water and soaked for two or three days; taken out and made into the proper shape, rubbed with charred grass, greased well, and carved in various designs with an opossum's tooth.
Boomerangs have many uses--in peace two clicked together as a musical instrument, as a war weapon, and as a weapon in the chase.
