There are the war boomerang, hunting boomerang, and amusement boomerang. This last is used for light hunting, such as killing ducks, cockatoos, and parrots, and is the one that is referred to when speaking of the boomerang. These sticks measure from a foot and a half to three feet and a half in length, the fighting and hunting ones being the largest and heaviest. The hardest and toughest wood is selected, and the form of the weapon follows the grain of the wood; thus, if the crook of the root or limb is little or much, so is the form of the boomerang. You will find that nearly every one is of a different shape. In my collection I have them varying from almost straight to a shape like that of the letter V, nearly straight, curved, plain, ornamented, some with strange carvings, and all varying according to different sections of the country and individual tribes, each having its own make or style, showing respectively rough crudeness or considerable finish, and being especially characteristic in the ends or points--all of which a boomerang connoisseur will distinguish at once, and locate as to tribe and section.
