A servant girl who attended to the cattle on the Trwyn farm, near Abergwyddon, used to take food to 'Master Pwca,' as she called the elf. A bowl of fresh milk and a slice of white bread were the component parts of the goblin's repast, and were placed on a certain spot where he got them. One night the girl, moved by the spirit of mischief, drank the milk and ate most of the bread, leaving for Master Pwca only water and crusts. Next morning she found that the fastidious fairy had left the food untouched. Not long after, as the girl was passing the lonely spot, where she had hitherto left Pwca his food, she was seized under the arm pits by fleshly hands (which, however, she could not see), and subjected to a castigation of a most mortifying character. Simultaneously there fell upon her ear in good set Welsh a warning not to repeat her offence on peril of still worse treatment. This story 'is thoroughly believed in there to this day.'[18]
