The Dominion census of 1911 gives us the following figures of the population of these places, and of one or two other posts which will be referred to later:—Fort Good Hope, 434; Fort Liard, 136; Fort McPherson, 387; Fort Norman, 315; Fort Providence, 473; Fort Rea, 774; Fort Resolution, 766; Fort Simpson, 375; Fort Smith, 50; Fort Wrigley, 79; Hay river, 146. These figures do not represent only the local population at the posts, but in addition the inhabitants, white and red, of the surrounding districts. MACKENZIE NAVIGATION. For many years the Hudson’s Bay Company have maintained steam communication on the Mackenzie from Fort Smith to Fort McPherson by means of steamers. The pioneer steamer “Wrigley” is one of the historical associations of the country. According to Mr. William Ogilvie, the “Wrigley’s” log shows the following average between Fort Smith, the most southerly part of her run, and Fort McPherson, the most northerly, the distance between these points being about one thousand two hundred and seventy miles. From Fort Smith to Fort Resolution, nearly all on Great Slave river, average running time, about eighteen hours; between Resolution and Providence about seventeen hours, of which twelve and a half are in Great Slave lake; between Providence and Simpson about fourteen hours; Simpson to Wrigley about ten and a half; Wrigley to Norman, about fourteen hours; Norman to Good Hope, about thirteen hours; Good Hope to McPherson, about twenty-four and a half hours. The total running time is one hundred and twenty-three and one-half hours, somewhat over ten and a quarter miles an hour. [Illustration: A Typical “Husky” dog.] On “up” runs the following averages have been made:—McPherson to Good Hope, forty hours; Good Hope to Norman, thirty-four hours, Norman to Wrigley, thirty-nine hours; Wrigley to Simpson; nineteen hours; Simpson to Providence, about twenty-eight hours; Providence to Fort Rae, not certain, appears to be about thirteen hours; Providence to Resolution, about twenty hours; Resolution to Smith, about thirty-five hours; Resolution to Rae, about fifteen hours and a return about the same, as it is all lake water. The duration of these runs varied somewhat by the force and direction of the wind. The total running from McPherson to Smith as shown above is two hundred and fifteen and one-half hours, which give a rate of 5·9 miles per hour. The mean of the up and down times is a fraction over eight miles an hour, which is said to be her normal speed. A LONG NAVIGABLE STRETCH.
