Please note that this is an archival film that makes use of the word “Eskimo,” an outdated and offensive term. While the origin of the word is a matter of some contention, it is no longer used in Canada. The term was formally rejected by the Inuit Circumpolar Council in 1980 and has subsequently not been in use at the NFB for decades. This film is therefore a time-capsule of a bygone era, presented in its original version. The NFB apologizes for the offence caused.
