Puzzle jugs were designed to make it difficult for the drinker to drink from them, unless he/she knew their secret. When the jug was tilted all the holes but one had to be stopped up, or liquid flowing up the hollow handle would spill out in all directions. This puzzle jug features the following inscription on the body:
'Within this jug there is good liquor Fit for Parson or for Vicar But how to Drink and not to spill Will try the utmost of your skill'. 'Cymru am Byth' (Wales Forever) is inscribed on the bottom of the jug.
