Relying heavily upon oral tradition, the book embraces the diverse disciplines of folklore, history, language, geography, literature, sociology, agriculture, botany, and home economics. It covers emigration history, community and domestic lifestyles, religious and social structure (including songs, poems, legends, and folktales), customs and beliefs, and material culture. Discussions are supported throughout by testimonies of many Townshippers, quoted verbatim, enabling the "voice" of the Gael to continue to be heard. Oatmeal and the Catechism will be of great interest to scholars and students of Gaelic studies and folklore in addition to Quebecers and others whose Scottish ancestors settled in Quebec and eastern Canada and helped carve a country out of the wilderness.
