The Jesuit Relations document discusses the interactions between Jesuit missionaries and native tribes in New France such as the Montagnais and Huron. It describes how the Montagnais engaged in trading with the Jesuits and were viewed as more clever than European peasants. It also outlines some of the Huron's peculiar language practices and conjugation, their creation beliefs involving figures like Aataentsic and Tsouhendaia, and their tradition of large communal feasts.
