It is satisfactory to find that, although the Devil has had certain plants allotted to him wherewith to work mischief and destruction through the agency of demons, sorcerers, and witches, there are yet a great number of plants whose special mission it is to thwart Satanic machinations, to protect their owners from the dire effects of witchcraft or the Evil Eye, and to guard them from the perils of thunder and lightning. In our own country, Houseleek and Stonecrop are thought to fulfil this latter function; in Westphalia, the _Donnerkraut_ (Orpine) is a thunder protective; in the Tyrol, the Alpine Rose guards the house-roof from lightning; and in the Netherlands, the St. John’s Wort, gathered before sunrise, is deemed a protection against thunderstorms. This last plant is especially hateful to evil spirits, and in days gone by was called _Fuga dæmonum_, dispeller of demons. In Russia, a plant, called the _Certagon_, or Devil-chaser, is used to exorcise Satan or his fiends if they torment an afflicted mourner; and in the same country the _Prikrit_ is a herb whose peculiar province it is to destroy calumnies with which mischief-makers may seek to interfere with the consummation of lovers’ bliss. Other plants induce concord, love, and sympathy, and others again enable the owner to forget sorrow. Plants connected with dreams and visions have not hitherto received much notice; but, nevertheless, popular belief has attributed to some few--and notably the Elm, the Four-leaved Clover, and the Russian _Son-trava_--the subtle power of procuring dreams of a prophetic nature. Numerous plants have been thought by the superstitious to portend certain results to the sleeper when forming the subject of his or her dreams. Many examples of this belief will be found scattered through these pages.
