“He knows her shifts and haunts, And all her wiles and turns. The venom’d plants Wherewith she kills! where the sad Mandrake grows, Whose groans are dreadful! the dead-numming Nightshade! The stupefying Hemlock! Adder’s-tongue! And Martagan!” The association of plants with magic, sorcery, and the black art dates from remote times. The blind Norse god Hödr slew Baldr with a twig of Mistletoe. In the battles recorded in the Vedas as being fought by the gods and the demons, the latter employ poisonous and magical herbs which the gods counteract with counter-poisons and health-giving plants. Hermes presented to Ulysses the magical Moly wherewith to nullify the effects of the potions and spells of the enchantress Circe, who was well acquainted with all sorts of magical herbs. The Druids professed to know the secrets of many magical plants which they gathered with mysterious and occult rites. The Vervain, Selago, Mistletoe, Oak, and Rowan were all said by these ancient priests and lawgivers to be possessed of supernatural properties; and remnants of the old belief in their magical powers are still extant. In works on the subject of plant lore hitherto published in England, scarcely any reference has been made to the labours in the field of comparative mythology of Max Müller, Grimm, Kuhn, Mannhardt, De Gubernatis, and other eminent scholars, whose erudite and patient investigations have resulted in the accumulation of a vast amount of valuable information respecting the traditions and superstitions connected with the plant kingdom. Mr. Kelly’s interesting work on Indo-European Tradition, published some years ago, dealt, among other subjects, with that of plant lore, and drew attention to the analogy existing between the myths and folk-lore of India and Europe relating more especially to plants which were reputed to possess magical properties. Among such plants, peculiar interest attaches to a group which, according to Aryan tradition, sprang from lightning--the embodiment of fire, the great quickening agent: this group embraces the Hazel, the Thorn, the Hindu _Sami_, the Hindu _Palasa_, with its European congener the Rowan, and the Mistletoe: the two last-named plants were, as we have seen, employed in Druidic rites. These trees are considered of good omen and as protectives against sorcery and witchcraft: from all of them wishing-rods (called in German _Wünschelruthen_) and divining-rods have been wont to be fashioned--magical wands with which, in some countries, cattle are still struck to render them prolific, hidden springs are indicated, and mineral wealth is discovered. Such a rod was thought to be the caduceus of the god Hermes, or Mercury, described by Homer as being a rod of prosperity and wealth. All these rods are cut with a forked end, a shape held to be symbolic of lightning and a rude effigy of the human form. It is interesting to note that in the _Rigveda_ the human
