It Is Many Years Since The First Glimmer Of The Theory Which Is Now Almost, If Not Quite, Reduced To Fact Dawned On My Mind. A Somewhat Extensive Course Of Miscellaneous And Obsolete Reading Had Done A Great Deal To Prepare The Way, And, Later, When I Became Somewhat Of A Specialist, And Immersed Myself In The Studies Known As Ethnological, I Was Now And Then Startled By Facts That Would Not Square With Orthodox Scientific Opinion, And By Discoveries That Seemed To Hint At Something Still Hidden For All Our Research. More Particularly I Became Convinced That Much Of The Folk-lore Of The World Is But An Exaggerated Account Of Events That Really Happened, And I Was Especially Drawn To Consider The Stories Of The Fairies, The Good Folk Of The Celtic Races. Here, I Thought I Could Detect The Fringe Of Embroidery And Exaggeration, The Fantastic Guise, The Little People Dressed In Green And Gold Sporting In The Flowers, And I Thought I Saw A Distinct Analogy Between The Name Given To This Race (supposed To Be Imaginary) And The Description Of Their Appearance And Manners.
