In "The Jesuit Missions," Marquis likely explores the history and activities of the Jesuit missions in Canada, focusing on the efforts of the Jesuit missionaries in the context of North American colonization and interactions with Indigenous peoples. For readers interested in the history of Jesuit missions in Canada, Indigenous-European relations, and the broader history of Western Canada, Thomas Guthrie Marquis' work provides valuable insights into the religious and cultural dynamics of this historical period.
