19 perforation. In Britain and many parts of Europe, tombs and blocks of rock are often pitted with holes. These are known as Fig. 19. Holed Dolmen. " cup-marks " and are in some parts, at certain times, filled with butter or lard, presumably as offerings to the souls of the dead. This superstition has been incorporated, like many others, with Christianity, and in many churches in Germany and Sweden holes were made in the stones of the walls. Strange customs and practices have become connected with these holes, such as blowing into them as a remedy for maladies and epidemics. Other holed stones exist, through which it has been the custom to pass the hand in making a contract as a sign of fidelity, and from this is to be traced the use of our wedding-ring. The broken-ring was also recognised by the early builders of the tumuli, and around their barrows is usually found a trench or a circle of stones which is incomplete. The same feature exists on many of the incised stones. This idea has come down to us in the supersti- tion attaching to the Horseshoe which is so commonly found nailed to the door of the house as a protection against witches or for bringing good luck. Another kind of lucky stone is the fossil Echinus. In Essex these objects are called Fairy-loaves, and many people keep them in their cottages in the belief that their presence ensures a plentiful supply of bread. In the Romano-British villages they were collected, but for what purpose is not clear. That they were regarded with some superstitious respect by early man is shown by the interesting discovery made by Mr. Worthington Smith of a barrow containing the bones of a young woman and child, which was surrounded by a ring formed of about 500 of these fossil echini.
