Now we come to an entirely new region, in which, however, we find, under other forms, the same creatures which have already been described. From the sunny East we pass to the cold and frozen North. Here the Scandinavian countries--Norway, Sweden, and Denmark--are wonderfully rich in dwarfs, and giants, and trolls, and necks, and nisses, and other inhabitants of Fairyland; and with these we must also class the Teutonic beings of the same kind; and likewise the fairy creatures who were once supposed to dwell in our islands. The Elves of Scandinavia, with whom our own Fairies are closely allied, were a very interesting people. They were of two kinds, the White and the Black. The white elves dwelt in the air, amongst the leaves of trees, and in the long grass, and at moonlight they came out from their lurking-places, and danced merrily on the greensward, and played all manner of fantastic tricks. The black elves lived underground, and, like the dwarfs, worked in metals, and heaped up great stores of riches. When they came out amongst men they were often of a malicious turn of mind; they caused sickness or death, stole things from the houses, bewitched the cattle, and did a great deal of mischief in all ways. The good elves were not only friendly to man, but they had a great desire to get to heaven; and in the summer nights they were heard singing sweetly but sadly about themselves, and their hopes of future happiness; and there are many stories of their having spoken to mortals, to ask what hope or chance they had of salvation. This feeling is believed to have come from the sympathy felt by the first converts to Christianity with their heathen forefathers, whose spirits were supposed by them to wander about, in the air or in the woods, or to sigh within their graves, waiting for the day of judgment. In one place there is a story that on a hill at Garun people used to hear very beautiful music. This was played by the elves, or hill folk, and any one who had a fiddle, and went there, and promised the elves that they should be saved, was taught in a moment how to play; but those who mocked them, and told them they could never be saved, used to hear the poor elves, inside the hill, breaking their fairy fiddles into pieces, and weeping very sadly. There is a particular tune they play, called the Elf-King's tune, which, the story-tellers say, some good fiddlers know very well, but never venture to play, because everybody who hears it is obliged to dance, and to go on dancing till somebody comes behind the musician and cuts the fiddle-strings; and out of this tradition we have the story of the Pied Piper of Hamelin. Some of the underground elves come up into the houses built above their dwellings, and are fond of playing tricks upon servants; but they like only those who are clean in their habits, and they do not like even these to laugh at them. There is a story of a servant-girl whom the elves liked very
