The native, from long practice, can do astonishing things with this weapon. He seems to determine with great certainty what its crooked and distant flight shall be, and how and where it is to end. Thus he frequently amuses himself in hurling the formidable weapon to astonishing heights and distances from one spot to which the missile returns to fall beside him. Sometimes the earth is made a fulcrum to which the boomerang descends only to resume a longer and more sustained flight, or to leap, perhaps, over a tree and strike an object behind it.
The contrivance probably originated in the utility of such a missile for the purpose of killing ducks where they are very numerous, as on the interior rivers and lagoons and where, accordingly, we find it much more in use than on the seacoast and better made, being often covered with good carving.* (See Cambo, Volume 1, also small figures in Plate 28 above.)
(*Footnote. That Dampier saw this weapon also on the western coast in latitude 16 degrees 50 minutes is evident from the following observation. "These swords were afterwards found to be made of wood and rudely shaped something like a cutlass.")
SHIELD OR HIELEMAN.
There is also much originality in the shield or hieleman of these people. It is merely a piece of wood of little thickness and 2 feet 8 inches long, tapering to each end, cut to an edge outwards and having a handle or hole in the middle behind the thickest part. This is made of light wood and affords protection from missiles, chiefly by the facility with which it is turned round the centre or handle.
NARROW SHIELD, OR HIELEMAN.
SKILL IN APPROACHING THE KANGAROO.
Great ingenuity is necessary and is as cleverly practised by the natives in approaching the kangaroo. This they display in creeping, stalking with bushes, advancing behind trees, etc. and to such a degree are their wits sharpened by their appetites that they can even distinguish when the kangaroo kills a fly; and they consider in their proceedings, from the habit of the kangaroo to kill flies and smell the blood, whether the animal may discover from the blood the fly contains that men are near.
