scratch and tear them like cats and dogs; and often in the night frighten, in the shape of owls, thieves and lovers, or, like Will-'o-the-wisps, lead them astray into bogs and marshes, and perhaps up to those who are in pursuit of them. The Black Dwarfs wear black jackets and caps, are not handsome like the others, but on the contrary are horridly ugly, with weeping eyes, like blacksmiths and colliers. They are most expert workmen, especially in steel, to which they can give a degree at once of hardness and flexibility which no human smith can imitate; for the swords they make will bend like rushes, and are as hard as diamonds. In old times arms and armour made by them were in great request: shirts of mail manufactured by them were as fine as cobwebs, and yet no bullet would penetrate them, and no helm or corslet could resist the swords they fashioned; but all these things are now gone out of use. These Dwarfs are of a malicious, ill disposition, and delight in doing mischief to mankind; they are unsocial, and there are seldom more than two or three of them seen together; they keep mostly in their hills, and seldom come out in the daytime, nor do they ever go far from home. People say that in the summer they are fond of sitting under the elder trees, the smell of which is very grateful to them, and that any one that wants anything of them must go there and call them. Some say they have no music and dancing, only howling and whimpering; and that when a screaming is heard in the woods and marshes, like that of crying children, and a mewing and screeching like that of a multitude of cats or owls, the sounds proceed from their midnight assemblies, and are made by the vociferous Dwarfs. The principal residence of the two first classes of the underground-people in Rügen is what are called the Nine-hills, near Rambin. These hills lie on the west point of the island, about a quarter of a mile from the village of Rambin in the open country. They are small mounds, or Giants' graves (_Hünengräber_), as such are called, and are the subject of many a tale and legend among the people. The account of their origin is as follows:--
