Indians in the Fur Trade: Their Roles as Trappers, Hunters, and Middlemen in the Lands Southwest of Hudson Bay, 1660-1870, first published in 1974, remains the classic study of the Assiniboine and western Cree of southern Manitoba and Saskatchewan and their role in the fur trade. The economic aspects of the fur trade are paramount in this cultural geography of Western Canada. Ray has painstakingly examined the Hudson's Bay Company records to uncover the nature of the interdependence between fur traders and First Nations. He concludes that generally these were peaceful relationships based on cooperation. This edition contains a new introduction and an update on sources.
