the end of the rainy season the new and unripe yams have come in, and dysentery rages, decimating the villages; or, when in hot and damp years an infectious disease passes over the district, taking heavy toll, this means that the tauva’u have come from the South, and that, invisible, they march through the villages, rattling their lime gourds, and with their sword-clubs or sticks hitting their victims, who immediately sicken and die. The tauva’u can, at will, assume the shape of man or reptile. He appears then as a snake, or crab, or lizard, and you recognise him at once, for he will not run away from you, and he has as a rule a patch of some gaudy colour on his skin. It would be a fatal thing to kill such a reptile. On the contrary, it has to be taken up cautiously and treated as a chief; that is to say, it is placed on a high platform, and some of the valuable tokens of wealth—a polished green stone blade, or a pair of arm-shells, or a necklace of spondylus shell beads must be put before it as an offering.
It is very interesting to note that the tauva’u are believed to come from the Northern coast of Normanby Island, from the district of Du’a’u, and more especially from a place called Sewatupa. This is the very place where, according to Dobuan belief and myth, their sorcery originated. Thus, what to the local tribes of the originating place is ordinary sorcery, practised by men, becomes, when looked at from a great distance, and from an alien tribe, a non-human agency, endowed with such super-normal powers as changing of shape, invisibility, and a direct, infallible method of inflicting death.

A much less dangerous being is the tokway, a wood-sprite, living in trees and rocks, stealing crops from the field and from the yam-houses, and inflicting slight ailments. Some men in the past have acquired the knowledge
