But again, why were the stones swallowed? What does all this swallowing mean? Zeus of course swallowed Metis in order to have her _mana_ inside him. That is sensible enough. Do medicine men or Theoi ever actually swallow smooth stones in order to get the fire-power or other magic inside them? In Mexico the devils which are sucked out of the body in curing diseases are usually in the form of stones. For instance, in the ceremony of the Huichol tribe, where the gods are healed of their weariness by the Dawn-Star, Kaiumari, sucking ‘stones and the like’ out of them.[62] The same practice is common among Australian blacks. Mr. Marett refers me to a still better case. Among the Yuin of New South Wales the word _joïa_, which is almost like _mana_ and is used to denote the immaterial force in sacred animals, is actually the name of certain stones like these. They are commonly quartz-crystals or bits of glass, but also we hear of Kunambrun, a black stone, apparently lydianite. A black stone probably means thunder. The medicine man often carries these stones in his mouth, and when he sends out a curse or a blessing he projects them out of himself into his victim ‘like the wind,’ that is, invisibly and impalpably.[63] The actual swallowing seems strange, unless it was a mere fraud. But I used to know an Australian blackfellow--I never thought of asking his tribe--who used to put stones in his mouth and give or sell them to the boys of the neighbourhood as bearing a charm in consequence. They were sure to hit what they were aimed at, unless the aim was very bad. I suppose he put a lot of his _mana_ into them. One of the ways in which a Papuan chief causes death, according to the report of Dr. Bellamy in the White Book for 1907, is to send to a man a present of a smooth stone. The man recognizes the meaning of the stone, and wastes away. Dr. Bellamy cured some by the application of strong smelling salts, which drove away the devils. Presumably the chief had put his _mana_ on the stone in some very strong way. Lastly, there is another element in this story which calls for explanation from better anthropologists than myself; I mean the constant reference to ‘hiding’ or ‘concealment’. Ouranos (157) _hid_ all his children in a secret place of the Earth; this gave pain to Earth, and she groaned, being squeezed by them. Earth again (482) took Zeus and _hid_ him in a cave. Kronos _put the stone inside_ him--surely a form of hiding. The Titans _were hidden away_--κεκρύφατο, by Kronos (729) till Zeus brought them again to light. Lastly and most important, Zeus _hid away fire_ from man, κρύψε δὲ πῦρ.
