Of all these, however, the Mandrake (_Mandragora_) is connected with the most extraordinary and remarkable superstitions. The plant is distinctly poisonous, and has peculiar divided roots which sometimes have a very rough resemblance to the human body. It was supposed to be alive, and to utter the most piercing shrieks when it was pulled out of the ground. In those accounts, which are based on that given by Josephus, it is the _person_ who pulls out the root, and not the plant, that shrieks, subsequently rolls on the ground, and finally dies in torments. Therefore, if you wish to pull up a mandrake, the correct course to pursue is as follows: Tie a dog to the plant by its tail, and then whip the dog. It will pull up the mandrake, and then die in frightful agony!
