'Even in Edinburgh, little bands of the faithful may be seen making their way through the King's Park to Arthur's Seat, and, as in the eighteenth century,
ON May-Day, in a fairy ring,
We've seen them round St. Anton's spring,
Frae grass the caller dew-drops wring,
To weet their een,
And water clear as crystal spring,
To synd them clean.'
