1. There may enter into any animal's body (generally a leopard's) some spirit, or, temporarily, even the soul of a living human being. The animal then, guided by human intelligence and will, exercises its strength for the purposes of the temporary human possessor. Many murders are said to be committed in this way, after the manner of the mythical German wehr-wolf or the French loup-garou. This belief in demoniacal possession of a lower animal must not be confounded with the equally believed transmigration of souls. The former is widespread over at least a third of the African continent. In Mashona-land "they believe that at times both living and dead persons can change themselves into animals, either to execute some vengeance, or to procure something they wish for; thus, a man will change himself into a hyena or a lion to steal a sheep and make a good meal off it; into a serpent to avenge himself on some enemy. At other times, if they see a serpent, it is one of the Matotela tribe or slave tribe, which has thus transformed himself to take some vengeance on the Barotse."[27] 2. Another manifestation is that of the uvengwa. It is claimed to be not simply spiritual, but tangible. It is the self-resurrected spirit and body of a dead human being. It is an object of dread, and is never worshipped in any manner whatever. Why it appears is not known. Perhaps it shows itself only in a restless, unquiet, or dissatisfied feeling. It is white in color, but the body is variously changed from the likeness of the original human body. Some say that it has only one eye, placed in the centre of the forehead. Some say that its feet are webbed like an aquatic bird. It does not speak; it only wanders, looking as if with curiosity. My little cottage at Batanga is a mile and a half from the three chief dwellings of the station. One afternoon in 1902 I went to the station, leaving my cook and his wife in charge of the cottage. When I returned late at night, he asserted that an uvengwa had come there. A few yards in front of the door of the house is a mango tree with its very dense dark foliage. The trunk is divided a few feet from the ground. The light from the open door streamed into a part of the front yard, leaving the tree trunk in dark shadow. The woman going out of the door had started back, screaming to her husband that she saw an uvengwa standing in the crotch of the tree and peering around one of the branches. The husband went to the door. He asserted to me that he also had seen the form. In their terror, neither of them made any investigation. Possibly a chalk-whitened thief had taken advantage of my absence to prowl about. But the two witnesses rejected such a suggestion; they were sure it was a visitor from some grave.
