Mr. Diamond Jenness, Division of Anthropology, National Museum of 
Canada, not only suggested the field work among the Beaver Indians, but 
supplied the data collected by himself on the Sekani and Carrier Indians 
which form the basis of a large part of the report. To him the author 
gladly expresses his great indebtedness. Thanks are due to Mr. Harold 
Laird, Indian Agent for the Lesser Slave Lake Agency in whose territory 
these Indians have their reserves, for facilitating the work in very many 
ways. And, to Mr. Beaton, Hudson’s Bay Company, Old Fort St. John, 
to Mr. Harris, Hudson's Bay Company, Fort St. John, and to Mr. Russell,

Indians and for various kindnesses. And also, to Inspectors Hancock and
