"Possibly," said their host, "and yet it is a fact that these natives are undoubtedly more adept at casting various forms of wooden implements than any other people in the world.  Their very indolence leads them to adopt all sorts of easy-made weapons, and wood is surely one of the most common materials for the purpose one could find.  Clubs of all kinds are hurled at prey or human enemies.  Among these the boomerang is a favorite.  They have several forms.  One type is very light, round on one side and flat on the other, and slightly twisted on its axis.  It is used almost entirely for play, though sometimes to hurl at flocks of birds in the sky.  The war and hunting boomerangs are much heavier; they are bent differently, and do not return to the thrower, but are a deadly weapon in the hands of these bushmen at ranges up to four hundred feet.  But stone-pointed spears are their chief weapons."
