then, setting it upon the ground, fills it with water and washes the cat in it till the animal is nearly drowned, heavy rain will certainly follow. In this performance the inverted pan is intended, as Mr. Skeat was told, to symbolise the vault of heaven.​[893] [Sidenote: Belief that twins can control the weather. Superstitions as to twins among the Indians of British Columbia. Superstitions as to twins in West Africa.] There is a widespread belief that twin children possess magical powers over nature, especially over rain and the weather. This curious superstition prevails among some of the Indian tribes of British Columbia, and has led them often to impose certain singular restrictions or taboos on the parents of twins, though the exact meaning of these restrictions is generally obscure. Thus the Tsimshian Indians of British Columbia believe that twins control the weather; therefore they pray to wind and rain, “Calm down, breath of the twins.” Further, they think that the wishes of twins are always fulfilled; hence twins are feared, because they can harm the man they hate. They can also call the salmon and the olachen or candle-fish, and so they are {p263} known by a name which means “making plentiful.”​[894] In the opinion of the Kwakiutl Indians of British Columbia twins are transformed salmon; hence they may not go near water, lest they should be changed back again into the fish. In their childhood they can summon any wind by motions of their hands, and they can make fair or foul weather, and also cure diseases by swinging a large wooden rattle. Their parents must live secluded in the woods for sixteen months after the birth, doing no work, borrowing nobody’s canoes, paddles, or dishes, and keeping their faces painted red all the time. If the father were to catch salmon, or the mother were to dig clams, the salmon and the clams would disappear. Moreover the parents separate from each other, and must pretend to be married to a log, with which they lie down every night. They are forbidden to touch each other, and even their own hair. A year after the birth they drive wedges into a tree in the woods, asking it to let them work again when four more months have passed.​[895] The Nootka Indians of British Columbia also believe that twins are somehow related to salmon. Hence among them twins may not catch salmon, and they may not eat or even handle the fresh fish. They can make fair or foul weather, and can cause rain to fall by painting their faces black and then washing them, which may represent the rain dripping from the dark clouds.​[896] Conversely, among the Angoni of Central Africa there is a woman who stops rain by tying a strip of white calico round her black head,​[897] probably in imitation of the sky clearing after a heavy storm. The parents of twins among the Nootkas must build a small hut in the woods on the bank of a river, far from the village, and there they must live for two years, avoiding
