Of the things which the public magician sets himself to do for the good of the tribe, one of the chief is to control the weather and especially to ensure an adequate fall of rain. Water is the first essential of life, and in most countries the supply of it depends upon showers. Without rain vegetation withers, animals and men languish and die. Hence in savage communities the rain-maker is a very important personage; and often a special class of magicians exists for the purpose of regulating the heavenly water-supply. The methods by which they attempt to discharge the duties of their office are commonly, though not always, based on the principle of homoeopathic or imitative magic. If they wish to make rain they simulate it by sprinkling water or mimicking clouds: if their object is to stop rain and cause drought, they avoid water and resort to warmth and fire for the sake of drying up the too abundant moisture. Such attempts are by no means confined, as the cultivated reader might {p248} imagine, to the naked inhabitants of those sultry lands like Central Australia and some parts of Eastern and Southern Africa, where often for months together the pitiless sun beats down out of a blue and cloudless sky on the parched and gaping earth. They are, or used to be, common enough among outwardly civilised folk in the moister climate of Europe. I will now illustrate them by instances drawn from the practice both of public and private magic. [Sidenote: Examples of making rain by homoeopathic or imitative magic.
