To the kingdom of elf-land few English nursery poems have any reference. Our continental neighbours have preserved a few, but the major number are found in versions of the folk-lore tales belonging to the people dwelling in the hilly districts of remote parts of Europe. Norway, Switzerland, Italy, and even Poland present weird romances, and our own country folk in the "merrie north country," and in the lowlands of "bonnie Scotland," add to the collection. The age to which most of them may be traced is uncertain; at all events, they bear evidences of belonging to a period when nature worship was universal, and the veneration of the mysterious in life common to our ancestors. The Second Stone Age men, it is said, cremated their dead who were worthy of reverence, and worshipped their shades, and the nursery tales of pixies and goblins and elves are but the mythical remains of their once prevailing religion--universal the world over. The inception of this ancestral worship probably took place during that period known as the Neolithic Age, when the moon, stars, and sun no longer remained the mysterious in life to be feared and worshipped. In the dreary process of evolution a gradual development took place, and nature worship and ancestral veneration evolved into the more comprehensive systems of Buddha, Confucius, and the later polytheism of Greece, Ancient Tuscany, and Rome, leaving high and dry, stranded, as it were, in Northern Europe, Ireland, and North Britain, an undisturbed residuum of ante-chronological man's superstitions. Evidences of primitive man's religion are seen in the customs and practices of our rural folk to-day. In vast forest districts, or in hilly regions far away from the refining influences of social contact, the old-time superstitions lingered, changing little in the theme, and inspiring the succeeding generations, as they unfolded in the long roll-call of life, with the same fears of the mystery of death and of a future life. One of the customs of recent practice is fitly described as follows:-- In Yorkshire and in north-west Irish homesteads, and even far away in the East amongst the Armenian peasantry, a custom was, until late years, in vogue, of providing a feast for the departed relatives on certain fixed dates. All Hallows' Eve being one of the occasions a meal was prepared, and the feast spread as though ordinary living visitants were going to sit round the "gay and festive board." The chain hanging down from the centre of the chimney to the fireplace was removed--a boundary line of the domestic home--but at these times especial care was taken to remove it so that the "pixies and goblins and elves" could have a licence to enter the house. In spite of Christian teaching and other widening influences the belief remained fixed in the minds of the rural classes that elves, goblins, sprites, pixies, and the manes were stern realities.
