At the North Pole there is only one
direction-south. One could go south
in as many ways as there are points ON
the compass card, but every one of
these ways is south; east and west have
vanished. Tho hour of the day at the
pole is paradoxical conception, for
that point is the meeting place of every
meridian, and the time of NIL holds
good, so that it is any hour one cares
to mention. Unpunctuality is hence
impossible-but the question grows
complex and its practical solution con.
Germs few.
