According to Dr. Dieffenbach, the particular haunt of the witches is--or rather _was_, for Christianity has rapidly extended its blessed power over the population of New Zealand--a place called Urewera, in the North Island, between Hawkes Bay and Taupo. The natives of this wild and deserted district are reported to be the greatest witches in the country; are much feared and studiously avoided by the neighbouring tribes. When they come down to the coast, the natives there are almost afraid to oppose their most extravagant demands, lest they should incur their displeasure. It is said that they use the saliva of the people they design to bewitch, and, therefore, visitors carefully conceal it, so as to deprive them of the opportunity of working mischief. Yet, like the witches and sorcerers of mediæval England, they appear to be more sinned against than sinning, and by no means to deserve the ill reputation which attaches to them. It is a curious fact, says Dr. Dieffenbach, which has been noticed in Tahiti, Hawaii, and the Polynesian islands generally, that the first intercourse of their inhabitants with Europeans produces civil war and social degradation, but that a change of ideas is rapidly effected, and the most ancient and apparently inveterate prejudices soon become a subject of ridicule, and are swept away. The grey priest, or tohunga, skilled in all the mysteries of witchcraft and native medical treatment, readily yields in his attendance on the sick to every European who possesses, or affects to possess, a knowledge of the science of surgery or medicine, and laughs at the former credulity of his patient. It is evident that, while deceiving others, he never deceived himself, and was well aware of the futility of his pretended remedies. When a New Zealand chief or his wife fell sick, the most influential tohunga, or some woman enjoying a special odour of sanctity, was instantly called in, and waited night and day upon the patient, sometimes repeating incantations over him, and sometimes sitting in front of the house, and praying. The following is the incantation which the priests profess to be a cure for headache. The officiant pulls out two stalks of the _Pteris esculenta_, from which the fibres of the root must be removed, and beating them together over the patient’s head, says this chant. It is entitled, “A prayer for the sick man, when his head aches: to Atua this prayer is offered, that the sick man may become well.”
