This paper provides detailed information about the land-owning customs of the Chipewyan caribou-eaters. Father Penard, who lived many years among the Chipewyan, describes a system of family land ownership, identical in its main outlines with the family hunting territories made familiar by the studies of Speck, Low, Davidson, and others among the Algonkian-speaking peoples. Prior to this study Simpson's account suggested family ownership of land among the Chipewyan. Penard's detailed account concurs with this theory. Moreover, the author suggests that further investigation will show the family hunting territory of the Chipewyan to be more or less prevalent over most of the northern Canadian area. The writer believes that this system is continuously prevalent from western Quebec, to the James Bay region, up the Albany to Lake St. Joseph, and around the Rainy River and Lake of the Woods districts as well.
