Education of children was in the form of myths and legends told in large group gatherings in the longhouse during the winter months. Expressions of politeness, etiquette, and proper behavior were usually emphasized. Horror stories indicated treatment by spirits, if caught. Monsters were obstacles to be conquered. Tribal history and biographical sketches were an important part of education. Apprentice training was the most popular method of teaching established skills, much of the teaching being done by older Indians and parents. A religious experience of a vision quest for the spirit weyekin was a part of growing up. The feast of the first fruits in the spring was another important religious ceremony. Religion was a central part of their culture and rules on religion, birth, adolescence, marriage, death and burial were taught. Magic, too. was important with the Shaman (witch doctor) as the leader. Some of these ceremonies were held as recently as 1940-1945.
