Folk-lore associations are multiplying and the students of literature and anthropology are joining forces in the effort to discover and classify the variant superstitions and legends of the past and of the races and tribes still in their childhood. Such activities are bringing to light a fascinating wealth of material from which the writers of ghostly tales may find countless plots. Such studies show how close akin the world is after all. A large number of books relating stories of brownies, bogles, fairies, banshees, wraiths, hobgoblins, witches, vampires, ghouls, and other superhuman personages have appeared. I am not including in this list the fairy stories that are written for juvenile consumption, but merely the folk-loristic or literary versions for adults. The most marked instance of the influence of folk-lore in supplying subject matter for literature is shown in the recent Celtic revival. The supernatural elements in the folk-tales of Ireland, Scotland, and Wales have been widely used in fiction, poetry, and the drama. In this connection one is reminded of Collins's _Ode on the Popular Superstitions of the Highlands Considered as the Subject for Poetry_. The Irish National School, with W. B. Yeats, John Synge, and Lady Gregory as leaders, have made the folk-tales of Ireland live in literature and the ghostly thrill of the old legends comes down to us undiminished. Lord Dunsany's work is particularly brilliant, going back to ancient times and re-creating the mythologic beings for us, making us friendly with the gods, the centaurs, the giants, and divers other long-forgotten characters. Kipling has made the lore of the Indian towns and jungles live for us, as Joel Chandler Harris has immortalized the legends of the southern negro. Thomas A. Janvier in his tales of old Mexico calls back the ghosts of Spanish conquerors and Aztec men and women, repeopling the ancient streets with courtly specters. The fondness for folk-loristic fiction is one of the marked aspects of Romanticism at the present time.
