Stories to Tell
1 There are about 16 or 17 tales in 'English Fairy and Folk Tales', Ed by Edwin Sidney Hartland.NY: Dover Publications,2000. (Originally published earlier)
2 'Peter and the Piskies' by Ruth Manning-Sanders. London: Oxford UP, 1958.
3 'The Magic Ointment' by Eric Qualye. London: Anderson press, 1986.
Many ideas in Hunt, 'Drolls, traditions and superstitions of Old Cornwall'. Llanerch Publishers, 1993. Facsimile reprint. Just tell them but if you need a written story to 'tell from', you have to rewrite them yourself to be interesting for little kids. I have rewritten a few and can be found on this website.
There are some small publications that make Hunt's work more accessible:
1 Hunt. 'Cornish Folklore'. Truro: Tor Mark Press, pre 1980.
2 Hunt. 'Cornish Legends'. Truro: Tor Mark press, no date.
3 Hunt. 'Customs and Superstitions from Cornish Folklore'. Penryn: Tor Mark Press, 1991.
