I think if I were Welsh, this book might offend me -- because Charlotte Burne constantly refers to the Welsh as she writes about "lower races" and the cutesy little bits of folklore they follow.
But no matter. Though written in 1911 -- I have to remind myself of this; it's from a different era -- the book is a deeply satisfying guide to human folklore, and a must-read for people who want to create their own folklore as they write stories, novels and such. Every writer should have a copy of this book on his or her bookshelf, because in it Burne outlines the basics of folklore in an accessible, easy to fathom format that can work as a handy guide for writers.
Additionally, this is a wonderful book for amateur cultural anthropologists who might wonder why Burne isnt' bothering to study the folklore of the -- to use her phraseology -- "higher" races, because it's not only the primitives who have folklore.
