Note 109 — Chapter III · THE WEAPONS OF THE AGE OF WOOD: THE BOOMERANG AND THE SWORD OF WOOD; OF STONE, AND OF WOOD AND STONE COMBINED.
Reading edition
It derives from booroomooroong; and the latter denotes, among the Maoris, a part of the ceremonies practised when the boys are being made men. The symbol, we are told (Collins, New South Wales, p. 346), is knocking out a tooth with the aid of a throwing-stick. Mr. Howard Spenseley (loc. cit.) makes the average boomerang 60 centimètres long by 0·6 broad and 0·15 thick: he gives it a flight of 100 mètres.
