summer, although the resistance of the ether is encountered more
evenly by the two hemispheres, yet it is still felt principally in the
northern hemisphere, and the south pole remains practically protected.
It follows that the southern hemisphere, and particularly the south
polar regions are more or less completely sheltered the whole year
around. It might then be supposed that the impact of the particles of
the ether shouldered aside by the earth in its swift flight and the
compression produced in front of the advancing globe would tend to
raise the temperature of the northern hemisphere as compared with the
southern hemisphere, while the south pole, being more or less directly
in the wake of the earth, and in a region of rarefaction of the ether,
would constantly possess a remarkably low temperature.

Now, it is known that the south polar regions are more covered with
ice and snow than those of the north, and that the temperature there
the year around is lower. Whether this difference is owing to the
effects of the earth's journey through the ether, is a question.

The sun, too, moves with his northern hemisphere foremost, and it is
worthy of remark that it has been suspected that the northern
hemisphere of the sun radiates more heat than the southern.

But whatever effect it may or may not have upon the meteorological
condition of the earth, the fact that the solar system is thus
voyaging through space is in itself exceedingly interesting. Not the
wildest traveler's dream presents to the imagination such a voyage as
this on which every inhabitant of the earth is bound. A glance at a
star map shows that the direction in which we are going is carrying us
toward a region of the heavens exceedingly rich in stars, many, and
perhaps most, of which are greater suns than ours. There can be little
