CONGRATULATIONS go to readers Tony Racket and Geoff Hanson.

They both correctly identified that last week's Craven Curiosities were the small balls used in the game, Knurr and Spell.

Experts from Craven Museum and Gallery tell us: "The balls are about the same size as a large grape and made from shaped and polished stones.

"The balls are called knurrs and would be hit with a spell (a metre-long stick). The object of the game would be to see how far the player could hit the knurr – which propelled a metre in the air with a wooden trap – using a big swing of the spell, not unlike a golf swing.

"The game derives from Yorkshire and has been played here for well over half a millennium.

"It was particularly popular in the 1700 and 1800s. In the 1900s large crowds would go and watch matches although fewer people were playing the sport. In the 1970s the game's popularity grew again as many people became interested in reviving it but, today, the game has all but disappeared."
