But it is not the departments of medicine and surgery alone, important as these are to human welfare, which in Melanesia are directed and controlled by spiritual forces. The weather in those regions is also regulated by ghosts and spirits. It is they who cause the wind to blow or to be still, the sun to shine forth or to be overcast with clouds, the rain to descend or the earth to be parched with drought; hence fertility and abundance or dearth and famine prevail alternately at the will of these spiritual directors. From this it follows that men who stand on a footing of intimacy with ghosts and spirits can by judicious management induce them to adapt the weather to the varying needs of mankind. But it is to be observed that the supernatural beings, who are the real sources of atmospheric phenomena, have delegated or deputed a portion of their powers not merely to certain material objects, such as stones or leaves, but to certain set forms of words, which men call incantations or spells; and accordingly all such objects and formulas do, by virtue of this delegation, possess in themselves a real and we may almost say natural influence over the weather, which is often manifested in a striking congruity or harmony between the things themselves and the effects which they are calculated to produce. This adaptation of means to end in nature may perhaps be regarded as a beautiful proof of the existence of spirits and ghosts working their purposes unseen behind the gaily coloured screen or curtain of the physical universe. At all events men who are acquainted with the ghostly properties of material objects and words can turn them to account for the benefit of their friends and the confusion of their foes, and they do so very readily if only it is made worth their while. Hence it comes about that in these islands there are everywhere weather-doctors or weather-mongers, who through their familiarity with ghosts and spirits and their acquaintance with the ghostly or spiritual properties of things, are able to control the weather and to supply their customers with wind or calm, rain or sunshine, famine or abundance, at a reasonable rate and a moderate figure.617 The advantages of such a system over our own blundering method of managing the weather, or rather of leaving it to its own devices, are too obvious to be insisted on. To take a few examples. In the island of Florida, when a calm is wanted, the weather-doctor takes a bunch of leaves, of the sort which the ghost loves, and hides the bunch in the hollow of a tree where there is water, at the same time invoking the ghost with the proper charm. This naturally produces rain and with the rain a calm. In the seafaring life of the Solomon Islanders the maker of calms is a really valuable citizen.618 The Santa Cruz people are also great voyagers, and their wizards control the weather on their expeditions, taking with them the stock or log which represents their private or tame ghost and setting it up on a stage in the cabin. The presence of the familiar ghost being thus secured, the weather-doctor will undertake to provide wind or calm according to circumstances.619 We have already seen how in these islands the wizard makes rain by pouring water on the wooden posts which represent the rain-ghosts.620
