Anything that is extraordinary or unusual, is a subject of great dread to the natives: of this I had a singular instance at Moorunde. In March, 1843, I had a little boy living with me by his father's permission, whilst the old man went up the river with the other natives to hunt and fish. On the evening of the 2nd of March a large comet was visible to the westward, and became brighter and more distinct every succeeding night. On the 5th I had a visit from the father of the little boy who was living with me, to demand his son; he had come down the river post haste for that purpose, as soon as he saw the comet, which he assured me was the harbinger of all kinds of calamities, and more especially to the white people. It was to overthrow Adelaide, destroy all Europeans and their houses, and then taking a course up the Murray, and past the Rufus, do irreparable damage to whatever or whoever came in its way. It was sent, he said, by the northern natives, who were powerful sorcerers, and to revenge the confinement of one of the principal men of their tribe, who was then in Adelaide gaol, charged with assaulting a shepherd; and he urged me by all means to hurry off to town as quickly as I could, to procure the man's release, so that if possible the evil might be averted. No explanation gave him the least satisfaction, he was in such a state of apprehension and excitement, and he finally marched off with the little boy, saying, that although by no means safe even with him, yet he would be in less danger than if left with me. All natives of Australia believe in sorcery and witchcraft on the part of certain of their own tribe, or of others. To enable them to become sorcerers, certain rites must be undergone, which vary among the different tribes. Around Adelaide they have at one period to eat the flesh of young children, and at another that of an old man, but it does not appear that they partake more than once in their life of each kind. When initiated, these men possess extensive powers, they can cure or cause diseases, can produce or dissipate rain [Note 88 at end of para.], wind, hail, thunder, etc. They have many sacred implements or relics, which are for the most part carefully kept concealed from the eyes of all, but especially from the women, such as, pieces of rock crystal, said to have been extracted by them from individuals who were suffering under the withering influence of some hostile sorcerers; the pringurru, a sacred piece of bone (used sometimes for bleeding), etc. The latter, if burned to ashes in the fire, possesses mortiferous influence over enemies. If two tribes are at war, and one of either happens to fall sick, it is believed that the sickness has been produced by a sorcerer of the opposite tribe, and should the pringurru have been burnt, death must necessarily follow.
