erfly myths?

the belief held by the Blackfeet that dreams are brought to us in sleep by a erfly. Their sign for a erfly was a design roughly in the shape of a maltese cross with one arm horizontal and the other verticle. This sign was painted on a lodge to indicate that the style and method of painting the lodge were taught to the lodge owner in a dream. It was also the custom for a Blackfoot woman to embroider the sign of a erfly on a small peice of buckskin and tie this in her baby's hair when she wishes it to go to sleep. At the same time, she sings to the child a lulaby in which the erfly is asked to come flying about and put the child to sleep. Grinnell did not learn why or how the erfly bring sleep and dreams. However, he did note that the Blackfeet stated that the butterfly is soft and pretty and moves gently and that if you look at it for a long time you will go to sleep.
