This does not give a strictly correct result, as the sun’s declination, on which the length of the day depends, does not change uniformly, the daily change in June, when the sun has attained its greatest declination, being small as compared with that of September, when the sun is near the equator. Were the light of each day separately computed, the difference would be even more decidedly in favor of the north. In computing the above table, refraction has not been taken into account except in the case of Fort McPherson. Allowance for refraction would increase the duration of sunlight at all the other places, but much more in the north than in the south. As the table now stands it assigns to Fort McPherson eight hundred and thirty-two hours, or thirty-four and two-third days more sunlight than Ottawa, during a total period of two thousand five hundred and fifty-two hours. A better mode of comparison is to reduce the number of hours of sunlight at each place to days. It stands thus:—Ottawa, seventy-five days, five hours; Chipewyan, eighty-five days, twenty hours; Fort Simpson, eighty-nine days, eleven hours; Fort Good Hope, ninety-nine days, twenty-two hours; Fort McPherson, one hundred and nine days, twenty-one hours, and this out of a total of one hundred and twenty-three days.
