To return from European peasant-magic to that of savages, we find that when the Bushmen want wet weather they light fires, believing that the black smoke clouds will attract black rain clouds; while the Zulus sacrifice black cattle to attract black clouds of rain.(1) Though this magic has its origin in savage ignorance, it survives into civilisation. Thus the sacrifices of the Vedic age were imitations of the natural phenomena which the priests desired to produce.(2) "C'etait un moyen de faire tombre la pluie en realisant, par les representations terrestres des eaux du nuage et de l'eclair, les conditions dans lesquelles celui-ci determine dans le ciel l'epanchement de celles-la." A good example of magical science is afforded by the medical practice of the Dacotahs of North America.(3) When any one is ill, an image of his disease, a boil or what not, is carved in wood. This little image is then placed in a bowl of water and shot at with a gun. The image of the disease being destroyed, the disease itself is expected to disappear. Compare the magic of the Philistines, who made golden images of the sores which plagued them and stowed them away in the ark.(4) The custom of making a wax statuette of an enemy, and piercing it with pins or melting it before the fire, so that the detested person might waste as his semblance melted, was common in mediaeval Europe, was known to Plato, and is practised by Negroes. Some Australians take some of the hair of an enemy, mix it with grease and the feathers of the eagle, and burn it in the fire. This is "bar" or black magic. The boarding under the chair of a magistrate in Barbadoes was lifted not long ago, and the ground beneath was found covered with wax images of litigants stuck full of pins. (1) Callaway, i. 92. (2) Bergaigne, Religion Vedique, i. 126-138, i., vii., viii. (3) Schoolcraft, iv. 491. (4) 1 Samuel vi. 4, 5. The war-magic of the Dacotahs works in a similar manner. Before a party starts on the war-trail, the chief, with various ceremonies, takes his club and stands before his tent. An old witch bowls hoops at him; each hoop represents an enemy, and for each he strikes a foeman is expected to fall. A bowl of sweetened water is also set out to entice the spirits of the enemy.(1) The war-magic of the Aryans in India does not differ much in character from that of the Dacotahs. "If any one wishes his army to be victorious, he should go beyond the battle-line, cut a stalk of grass at the top and end, and throw it against the hostile army with the words, Prasahe kas trapasyati?--O Prasaha, who sees thee? If one who has such knowledge cuts a stalk of grass and throws the parts at the hostile army, it becomes split and dissolved, just as a daughter-in-law becomes abashed and faints when seeing her father-in-law,"--an allusion, apparently, to the widespread tabu which makes fathers-in-law, daughters-in-law, sons-in-law, and mothers-in-law avoid each other.(2) (1) Schoolcraft, iv. 496.
