2. When man first began to think about the world around him he must have noted (what he, in common with other animals, had unconsciously acted upon in the past) that day and night and the seasons arrived in regular succession, the same stars rose and set, an animal reproduced its own kind, in fact that there was a uniformity in nature. But side by side with these natural sequences there were irregularities. Some days were shorter than others, some were bright, others cloudy, the length and character of the seasons varied from year to year, some stars had a course in the heavens independent of the majority. Again, he might early have noticed that many of these fluctuations in sunshine and rain, in heat and cold, affected him directly or indirectly by influencing vegetation. We need not be surprised, therefore, if he came to the conclusion that it would be better for him if he exerted himself to regulate matters somewhat, but then the difficulty would arise, what was he to do?

The unenlightened mind does not discriminate between cause and effect, and imagines that as like produces like, so a result can be attained by imitating it. Hence arose Mimetic or Symbolic Magic, which, following Dr. Hirn, is better termed Homœopathic Magic, which is occult influence based upon a likeness between things ([32, 282]). On this was founded the mediæval medical theory known as the Doctrine of Signatures, which supposes that plants and minerals indicate by their external characters the diseases which nature intended them to remedy.

It would be easy to give a large number of examples to illustrate homœopathic magic, but a few will suffice. Thus the Euphrasia, or eye-bright, was, and is, supposed to be good for the eyes, on the strength of a black pupil-like spot in its corolla ([70, 123]). The yellow turmeric, or saffron, cured jaundice. The roots of roses or their slips, with their knots removed and set amongst broom, will bring forth yellow roses ([47, x. 70]).

The influence of homœopathic magic can be traced in beliefs and practices from the lowest savages to civilised nations. The magician who works by similarities makes representations of things or beings, in order to acquire an influence over them. By dramatic or pictorial imitation heavenly bodies are influenced, rain is made, plants and animals are increased, animals enticed to their destruction, human beings acted upon.

When it was wished to cause rain to fall in Murray Island, Torres Straits, the rain-maker scooped a hole in the ground, and lined it with leaves and placed in it a rude stone image of a man which had previously been anointed with oil and rubbed with scented grass; then he poured the decoction of minced leaves of various plants mixed with water over the image—the image being so laid in the hole as to point to the quarter from which the rain was expected. Earth was heaped over the image and leaves and shells placed on the mound, and all the while the rain-maker muttered an incantation in a low sepulchral tone. Four large screens composed of plaited coco-nut leaves were placed at the head, foot, and sides of the grave to represent clouds; on the upper part of each was fastened a blackened oblong of vegetable cloth to mimic a black thunder-cloud, and coco-nut leaves, with their leaflets pointing downwards, were suspended close by to represent rain. A torch was ignited and waved lengthwise over the grave; the smoke represented clouds and the flames mimicked lightning, and a bamboo clapper was sounded to imitate thunder.

The rain was supposed to come when the decoction round the image was rotten. The incantation consisted of enumerating various aspects of certain forms of clouds. Rain could be made in this manner only by one section of the community, and amongst these one or two men had a much greater reputation than the others ([29, vi.]).

This may be taken as an example of a typical rain-making ceremony, in which all the phenomena of a thunder shower are imitated.

If a native of Mabuiag, in Torres Straits, required rain he went to the rain-maker and asked him to make some. The latter might reply, ‘You go and put some more thatch on your house and on mine too’; this was to keep out the forthcoming rain. The rain-maker painted the front of his body white, and the back black. This was explained by my informant thus: ‘All along same as clouds, black behind, white he go first,’ or he painted his body with black spots to make the clouds come separately; when they congregated, the rain fell. The rain-maker put ‘medicine’ in his right hand and waved it towards his body and chanted an incantation. To stop the rain the rain-maker put red paint on the crown of his head, to represent the shining sun, and ruddled his body all over. He then lay doubled up and was closely surrounded with three mats, so that no wind could penetrate to him. Finally he burnt some leaves on the sea-shore close to the water, on a rising tide; the smoke represented the clouds, and as it was dissipated so they disappeared, and as the encroaching sea washed away the ashes, so the clouds were scattered ([29, v. 350]).

In the island of Muralug certain old men could raise a wind by very rapidly whirling a thin bull-roarer attached to a long string. More wind could be obtained by climbing to the top of a tree and performing there. In this case the noise made by the bull-roarer imitated that produced by a gale of wind ([29, v. 352]).

Examples of the magical increase of plants are found in the ‘yam stones’ placed in their gardens by various Papuans, which by their rounded shape suggest the actual tubers ([28, 202]; [29, vi.]).
