The fog, clouds, vapor, and peculiar kind of snow met with at the poles ought to set one to thinking what produces them. There are too many peculiar conditions to come from no particular cause, and all just alike at the North and South poles. Take Africa and Norway, regions which are not at all alike in anything--the game, the vegetation, the people, the climates are as different as the pies a man's wife makes from those his mother used to make.
