Each chief has his own especial rain-maker, who is also the "Ngaka," or doctor. These men are held in great veneration by the people, who firmly believe they are possessed of supernatural power. Of course the "Ngaka" encourages this belief in every possible way, playing upon the credulity of his victims with the solemnity of a seer of old. He makes a paying business of it, too, exacting a goat or sheep, or even several head of cattle, as payment, according to the magnitude of the service performed by him. He knows the family history of each individual in his particular district, and, in a quiet, unnoticed way, finds out everything likely to be of use to him either in his profession as doctor or as prophet. He is a student of nature to no small degree, and certainly possesses a wide knowledge of the use of herbs. He has a wonderful magnetic influence over others, the result, I suppose, of superior brain development. When rain is needed, the chief calls the "Ngaka," who, armed with his divining rod, arrives at the khotla to hear what is required of him. He then proceeds to "doctor" the rod with a black pigment and human blood (I fancy in the remote past a human victim was always sacrificed, but times are changed, and a few drops of blood are all the rain-god now requires). The people assemble in the village and watch him as he ascends the nearest mountain. When on the summit, he raises his rod heavenward, and calls "Pula ha-e-na a bolokue" (Rain come down and save us). This he does several times, and goes through a considerable amount of pantomime; but, as no one is allowed to go near him, only his gestures can be followed after that one loud call. When he is satisfied that rain is coming, he runs back to the village singing. The people join him, and indulge in feasting and merry-making. If, after seven days, no rain comes, there is something wrong with the divining-rod, which has displeased the rain-god, so the rod is again "doctored," and "Ngaka" goes off once more to the mountain, where he remains in supplication until "he brings down rain." In reality, these men consult the heavens before consenting to make rain, and consequently are seldom unsuccessful. Certain children are selected, in infancy or early childhood, to be made doctors. Their poor little bodies are cut, and various "medicines" rubbed into the wounds, which bestow powers of divination, of healing, and of witchcraft upon the children. They become restless and unable to sleep in the hut at night, and, as their minds develop, they are trained by the old doctors to succeed them.
