In either case it is held by the lower part in the palm of the hand, clasped firmly by the three lower fingers, with its upper part resting between the fore-finger and the next; the head of the spear, in which is a small hole, is fitted to the kangaroo tooth, and then coming down between the fore-finger and thumb, is firmly grasped for throwing; the arm is then drawn back, the weapon levelled to the eye, a quivering motion given to it to steady it, and it is hurled with a rapidity, force, and precision quite incredible.
The Wangn or wangno (the boomerang of Eastern and kiley of Western Australia) is another simple but destructive weapon, in the hands of the native.

It consists of a thin, flat, curved piece of hard wood, about two feet long, made out of the acacia pendula or gum-scrub, the raspberry-jam wood, or any other of a similar character, a branch or limb is selected which has naturally the requisite curve (an angle from one hundred to one hundred and thirty degrees) and is dressed down to a proper shape and thickness, and rounded somewhat at the bend, those whose angles are slightly obtuse, are usually thrown with the sharp edge against the wind, and go circling through the air with amazing velocity, and to a great height and distance, describing nearly a parabola and descending again at the foot of the person who throws them; those which have the largest obtuse angle are thrown generally against the ground from which they bound up to a great height, and with much force.

With both, the natives are able to hit distant objects with accuracy, either in hunting or in war; in the latter case this weapon is particularly dangerous, as it is almost impossible, even when it is seen in the air, to tell which way it will go, or where descend.

I once nearly had my arm broken by a wangno, whilst standing within a yard of the native who threw it, and looking out purposely for it.
The (katta twirris) or two-edged sword is a formidable weapon, used among the tribes to the north of Adelaide, exclusively for war; another weapon, common among the same tribes, is the katta, a round chisel-pointed stick, about three feet long, and used principally in pitched battles between two individuals.
Another weapon is an angular piece of hard wood, pointed and shaped very much like a miner's pick, the longer or handle-end being rounded and carved, to give a firmer grasp; another dreadful weapon, intended for close combat, is made out of hard wood, from two to three feet long, straight and with the handle rounded and carved for the grasp, which has an immense pointed knob at the end; the bwirri, is also a weapon of hard wood about two feet long, rather slight and merely smoothed in the handle, with a round knob at the extremity, it is principally thrown, and with very great precision; but is more generally used after game than in warfare.
The shield (tar-ram) is made out of the bark or wood of the gum-tree, and varies in shape and device, the ordinary shield is about two or two and a half feet long, from eight to eighteen inches across, and tapering from the middle towards the extremities, two holes are made near the centre, through which a piece of wood is bent for a handle; shields are always carved and painted in time of war.
The implements made use of by the natives are not very numerous, and their general characteristics are nearly the same all over the continent.
The native hatchet is made of a very hard greenish-looking stone, rubbed to an edge on either side; it is fixed in the cleft of a stick, or a branch is doubled round it, and either tied or gummed to prevent its slipping.

The throwing sticks have generally a sharp piece of quartz or flint gummed on at the lower end, which is used as a knife or chisel; flints or muscle shells are used for skinning animals, dissecting food, cutting hair, etc.
The ngak-ko, a strong chisel-pointed stick, from three to four feet long, is used for dissecting the larger animals and fish, for digging grubs out of the trees, for making holes to get out opossums, etc., for stripping bark, ascending trees, for cutting bark canoes, and a variety of other useful purposes.
