Cock-haw.
This game is, I believe, known in other counties as “Cob-nut,” but in Cornwall the boys give the name of “Victor-nut” to the fruit of the common hazel, and play it to the words:
“Cock-haw! First blaw! Up hat! Down cap! Victor!”
The nut that cracks another is called a “cock battler.”
Children under the title of “Cock battler” often in country walks play a variation of Cock-haw with the “Hoary plantain,” which they hold by the tough stem about two inches from the head; each in turn tries to knock off the head of his opponent’s flower.
