After the heavy rain of a thunderstorm has washed the soil, it sometimes happens that a child, or a rustic, finds a wedge-shaped piece of metal or a few triangular flints in a field or near a road. There was no such piece of metal, there were no such flints, lying there yesterday, and the finder is puzzled about the origin of the objects on which he has lighted. He carries them home, and the village wisdom determines that the wedge-shaped piece of metal is a ‘thunder-bolt,’ or that the bits of flint are ‘elf-shots,’ the heads of fairy arrows. Such things are still treasured in remote nooks of England, and the ‘thunder-bolt’ is applied to cure certain maladies by its touch.

As for the fairy arrows, we know that even in ancient Etruria they were looked on as magical, for we sometimes see their points set, as amulets, in the gold of Etruscan necklaces. In Perugia the arrow-heads are still sold as charms. All educated people, of course, have long been aware that the metal wedge is a celt, or ancient bronze axe-head, and that it was not fairies, but the forgotten peoples of this island who used the arrows with the tips of flint. Thunder is only so far connected with them that the heavy rains loosen the surface soil, and lay bare its long hidden secrets.

There is a science, Archæology, which collects and compares the material relics of old races, the axes and arrow-heads. There is a form of study, Folklore, which collects and compares the similar but immaterial relics of old races, the surviving superstitions and stories, the ideas which are in our time but not of it. Properly speaking, folklore is only concerned with the legends, customs, beliefs, of the Folk, of the people, of the classes which have least been altered by education, which have shared least in progress. But the student of folklore soon finds that these unprogressive classes retain many of the beliefs and ways of savages, just as the Hebridean people use spindle- whorls of stone, and bake clay pots without the aid of the wheel, like modern South Sea Islanders, or like their own prehistoric ancestors. The student of folklore is thus led to examine the usages, myths, and ideas of savages, which are still retained, in rude enough shape, by the European peasantry.
