AN extensive inquiry among traders, policemen, missionaries and Eskimos concerning the audibility of the aurora was made by members of the Canadian Polar party stationed near Chesterfield Inlet on the west coast of Hudson Bay. The majority of the white people who were questioned had more than twenty year's experience in the eastern Canadian arctic. The Eskimos were questioned only after we found that they were calling us “foolish white men”, because we had said that the aurora was inaudible. Natives living in the region extending from Repulse Bay in the north to Eskimo Point in the south, and from Baker Lake in the west to Southampton Island in the east were included in the inquiry.
