The Folk-lore of Plants
T. F. Thiselton-Dyer40"Rowan-ash, and red thread, Keep the devils from their speed." In the same way the mothers in Esthonia put some red thread in their babies' cradles as a preservative against danger, and in China something red is tied round children's wrists as a safeguard against evil spirits. By the aid of comparative folk-lore it is interesting, as in this case, to trace the same notion in different countries, although it is by no means possible to account for such undesigned resemblance. The common ash (Fraxinus excelsior), too, is a lightning plant, and, according to an old couplet: "Avoid an ash, It counts the flash." Another tree held sacred to Thor was the hazel (Corylus avellana), which, like the mountain-ash, was considered an actual embodiment of the lightning. Indeed, "so deep was the faith of the people in the relation of this tree to the thunder god," says Mr. Conway,[5] "that the Catholics adopted and sanctioned it by a legend one may hear in Bavaria, that on their flight into Egypt the Holy Family took refuge under it from a storm."
