I have only once seen witchcraft on its path. I had been sitting late in my hut writing notes. About midnight, before retiring, I took a spear and went for my usual nocturnal stroll. I was walking in the garden at the back of my hut, amongst banana trees, when I noticed a bright light passing at the back of my servants' huts towards the homestead of a man called Tupoi. As this seemed worth investigation I followed its passage until a grass screen obscured the view. I ran quickly through my hut to the other side in order to see where the light was going to, but did not regain sight of it. I knew that only one man, a member of my household, had a lamp that might have given off so bright a light, but next morning he told me that he had neither been out late at night nor had he used his lamp. There did not lack ready informants to tell me that what I had seen was witchcraft. Shortly afterwards, on the same morning, an old relative of Tupoi and an inmate of his homestead died. This event fully explained the light I had seen. I never discovered its real origin, which was possibly a handful of grass lit by some one on his way to defecate, but the coincidence of the direction along which the light moved and the subsequent death accorded well with Zande ideas (Evans-Pritchard 1937: 34).
