[From Mona Miscellany second series Manx Soc vol 21]
There was a servant girl at Bemahague, and the mistress wanted her
to go to Glen Crutchery Well to get a can of water before daylight,
and afterwards she was to be allowed to go to the fair. When going to
the well she met the old man of Glen Crutchery, who asked her where
she was going. "Going to your well for water," she said. He asked her
if there was no water in their own well? She said there was, but her
mistress had sent her. He gave her half-a-crown, and told her to take
water out of their own well. The girl received the money, which
confirmed the charm, and then went to the fair. When she returned
home the mistress asked her where she had procured the water, for she
had been churning all day and had got no butter?
It is said
"Vervain and dill
Hinders witches from their will."
