The Scope of the Survey. The survey was confined to the Mackenzie River District. The places visited were Fort Smith, Fort Resolution, Hay River, Fort Providence, Fort Simpson, Norman Wells, Fort Good Hope, Arctic Red River, Fort McPherson, Aklavik, Yellowknife, and Port Radium. Fort Norman and Fort Rae were not visited, but information in regard to these was obtained from medical officers for these areas. All but one doctor in the area were interviewed. The hospitals and schools were visited and the authorities in charge were most co-operative in supplying information. Useful interviews were had with the clergy, R.C.M.P., R.C.C.S., Hudson Bay Company officials, independent traders, oil and mine operators, and many other residents of the Territories.
