Dorset Folklorist, John Symonds Udal wrote in his book ‘Dorsetshire Folklore’ published in 1922 about the Abbotsbury Garland Day custom:
“Flower Custom (Garland Day). — They refer to a pleasing custom which still obtains on Old May Day (13th May). The children belonging to the crew of each boat build up a large garland of handsome flowers upon a frame, and carry it from house to house, usually getting a few pence apiece from those who can afford it. The people throng the beach, weather permitting, in the afternoon, when the garlands are taken out in boats and thrown into the sea. The late Lord Ilchester, the lord of the manor, had of late years provided an entertainment for the children, often close upon 200 in number, and was accustomed to attend them to the beach, where the vicar read a suitable portion of scripture, a psalm was sung, and prayer offered for the general welfare.
This custom is alluded to at somewhat greater length by Canon Mayo in a communication to Somerset and Dorset Notes and Queries, vol. iii, p. 231 (1893), entitled “Garland Day”, in which he states that it is also observed in the neighbouring villages of Swyre and Puncknoll, but that in them only one garland is provided, not one for each boat.”
