The so-called “snake-stones,” many specimens of which have been found in British barrows, bear in the Scottish Lowlands the designation “Adder Stanes.” They are also sometimes called adder-beads or serpent-stones. For the Welsh they were _gleini na droedh_ and for the Irish _glaine nan druidhe_, the meaning being the same, “Druid’s glass.” Many interesting examples were added to the collection of the Museum of Scotch Antiquaries, one of these being of red glass, spotted with white; another of blue glass, streaked with yellow; other types were of pale green and blue glass, some of these being ribbed while others again were of smooth and plain surface. That the glass “snake-stones” were objects of considerable care and attention is indicated by the mending of a broken specimen shown by Lord Landesborough at a meeting of the Society of Antiquaries in 1850. This broken bead had been repaired and strengthened by the application of a bronze hoop.[456] The supposed snake-stones are also to be found among the Cornishmen, who sometimes call these objects _milprey_ or “thousand worms,” and they even lay claim to the power of forcing a snake to fabricate the “stone” by thrusting a hazel-wand into the spirals of a sleeping reptile. In another version it is not a bead that is formed but a ring which grows around a hazel-wand when a snake breathes on it. If water in which this ring has been dipped be given to a human being or an animal that has been bitten by a venomous creature, all ill effects of the bite will be warded off, the water acting as a powerful antidote to the poison.[457] The belief that the snake-stone of Welsh legend—in reality either a fossil or a bead—was evolved from the venom or saliva ejected by a concourse of hissing snakes, gave rise to a peculiar popular saying among the Welsh to the effect that people who are whispering together mysteriously, and apparently gossiping, or perhaps hatching some mischief, are “blowing the gem.”[458] Many of the glass beads known as “snake-stones” or “Druid’s glass” are perforated, and this is fancifully explained as being the work of one of the group of snakes which forms the bead. This particular snake thrusts its tail through the viscous mass before it has become hardened into a glass sphere. In various parts of Scotland such beads are treasured up by the peasants; according to the testimony of an English visitor of 1699, who reports that they were hung on children’s necks as protection from whooping-cough and other children’s diseases, and were also valued as talismans productive of good fortune and protective against the onslaught of malevolent spirits. To guard one of these precious beads from the depredations of the dreaded fairies the peasant would keep it enclosed in an iron box, this metal being much feared by the fairies.[459]
