(M54) Midsummer Eve is also the favourite time for procuring the divining-rod in Sweden. Some say that it should then be cut from a mistletoe bough.(236) However, other people in Sweden are of opinion that the divining-rod (_Slag ruta_) which is obtained on Midsummer Eve ought to be compounded out of four different kinds of wood, to wit, mistletoe, mountain-ash, the aspen, and another; and they say that the mountain-ash which is employed for this purpose should, like the mistletoe, be a parasite growing from the hollow root of a fallen tree, whither the seed was carried by a bird or wafted by the wind. Armed with this fourfold implement of power the treasure-seeker proceeds at sundown to the spot where he expects to find hidden wealth; there he lays the rod on the ground in perfect silence, and when it lies directly over treasure, it will begin to hop about as if it were alive.(237) (M55) A mystical plant which to some extent serves the same purpose as the divining-rod is the springwort, which is sometimes supposed to be caper-spurge (_Euphorbia lathyris_). In the Harz Mountains they say that many years ago there was a wondrous flower called springwort or Johnswort, which was as rare as it was marvellous. It bloomed only on St. John’s Night (some say under a fern) between the hours of eleven and twelve; but when the last stroke of twelve was struck, the flower vanished away. Only in mountainous regions, where many noble metals reposed in the bosom of the earth, was the flower seen now and then in lonely meadows among the hills. The spirits of the hills wished by means of it to shew to men where their treasures were to be found. The flower itself was yellow and shone like a lamp in the darkness of night. It never stood still, but kept hopping constantly to and fro. It was also afraid of men and fled before them, and no man ever yet plucked it unless he had been set apart by Providence for the task. To him who was lucky enough to cull it the flower revealed all the treasures of the earth, and it made him rich, oh so rich and so happy!(238)
