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.”
