          fall upon his favoured  home-land at the Pole.  Even  when  at  last
          he  sinks  again  from  view  he  covers  his  retreat  with  a  repetition
          of  the  deepening  and  fading  splendours  which  filled  his  long
          dawning,  as  if in these  pulses  of more and more  distant  light  he
          were  signalling  back  to  the  forsaken  world  the  promises  and
          prophecies  of  an  early  return. "*
              A  phenomenon  like  this  cannot  fail  to  be  permanently  im-
          pressed  on the memory of a  Polar observer,  and it will  be found
          later on that the oldest traditions of the Aryan race have preserved
          the  recollection  of a  period,  when  its  ancestors  witnessed  such
          wonderful  phenomenon,-a long and continuous  dawn  of several
          days,  with  its  lights  laterally  revolving  on  the  horizon,  in  their
          original  home.
              Such  are  the  distinguishing  characteristics  of  the  North
          Pole,  that is,  the  point where  the  axis  of the  earth terminates  in
          the  north.  But as  a  Polar home means  practically  a  home in the
          regions  round  about  the  North  Pole,  and  not  merely  the  Polar
          point,  we  must  now  see  what  modifications  are  necessary  to  be
          made  in  the  above  characteristics  owing  to  the  observer  being
          stationed a  little  to  the  south  of the  North  Pole.  We  have  seen
          that at the  Pole  the  northern  hemisphere  is  seen  spinning  round
          the  observer  and  all  the  stars  move  with  it in  horizontal  planes
          without  rising  or  setting;  while  the  other  celestial  hemisphere  is
          always  iilvisible.  But  when  the  observer  is  shifted  downwards,
          his  zenith  will  no  longer  correspond  with  the  Pole  Star,  nor  his
          horizon  with  the  celestial  equator.  For  instance  Jet  Z,  in  the
          annexed  figure,  be  the  zenith  of  the  observer  and P  the  celestial
          North  Pole.  When  the  observer  was  stationed  at  the  terrestrial
          North Pole,  his zenith coincided with P,  and his  horizon with  the
          celestial  equator,  with  the  result  that  all  the  stars  in  the  dome
          Q' PQ  revolved  round  him  in  horizontal  planes.  But  when  the
          zenith  is  shifted  to  Z,  this  state  of  things  is  at  once
          altered,  as  the  heavens  will  revolve,  as  before,  round  the  line
          POP',  and  not round  the zenith line ZOZ'.  When  the  observer
          was  stationed  at  the  North  Pole  these  two  lines  coincided  and
          hence  the  circles  of revolution  described  by  the  stars  round  the
          celestial  Pole  were -also  described  round the zenith line. But  when
          the  zenith  Z  is  different  from  P,  as in the figure,  the celestial
