In the evidence about to be presented there has been no selecting in favour of any one theory; it is presented as discovered. The only liberty taken with some of the evidence has been to put it into better grammatical form, and sometimes to recast an ambiguous statement when I, as collector, had in my own mind no doubt as to its meaning. Translations have been made as literal as possible; though sometimes it has been found better to offer the meaning rather than what in English would be an obscure colloquialism or idiomatic expression. The method pursued in seeking the evidence has been to penetrate as deeply and in as natural a way as possible the thoughts of the people who believe in fairies and like beings, by living among them and observing their customs and ways of thought, and recording what seemed relevant to the subject under investigation--chance expressions, and legends told under various ordinary conditions--rather than to collect long legends or literary fairy-stories. For these last the reader is referred to the many excellent works on Celtic folk-lore. We have sought to bring together, as perhaps has not been done before, the philosophy of the belief in fairies, rather than the mere fairy-lore itself, though the two cannot be separated. In giving the evidence concerning fairies, we sometimes give evidence which, though akin to it and thus worthy of record, is not strictly fairy-lore. All that we have omitted from the materials in the form first taken down are stories and accounts of things not sufficiently related to the world of Faerie to be of value here.
