During the summer, in the northern hemisphere, places near the North
Pole are in _continual sunlight_--the sun never sets to them; while
during that time places near the South Pole never see the sun. When it
is summer in the southern hemisphere, and the sun shines on the South
Pole without setting, the North Pole is entirely deprived of his light.
Indeed, at the Poles there is but _one day and one night_; for the sun
shines for six months together on one Pole, and the other six months on
the other Pole.
