  PRIMEVAL 
  MAN. 
  

  

  have 
  they 
  come 
  ? 
  What 
  could 
  have 
  tempted, 
  

   or 
  what 
  change 
  compelled, 
  a 
  tribe 
  of 
  men 
  

   to 
  leave 
  the 
  fine 
  regions 
  of 
  the 
  North, 
  to 
  

   travel 
  down 
  the 
  Cordillera, 
  or 
  backbone 
  of 
  

   America, 
  to 
  invent 
  and 
  build 
  canoes 
  which 
  

   are 
  not 
  used 
  by 
  the 
  tribes 
  of 
  Chili, 
  Peru, 
  and 
  

   Brazil, 
  and 
  then 
  to 
  enter 
  on 
  one 
  of 
  the 
  most

  countries 
  within 
  the 
  limits 
  of 
  the 
  

   globe

  There 
  can 
  be 
  but 
  one 
  explanation. 
  

   Quarrels 
  and 
  wars 
  between 
  tribe 
  and 
  tribe, 
  

   induced 
  by 
  the 
  mere 
  increase 
  of 
  numbers 
  

   and 
  the 
  consequent 
  pressure 
  on 
  the 
  means 
  of 
  

   subsistence, 
  have 
  been 
  always, 
  ever 
  since 
  Man 
  

   existed, 
  driving 
  the 
  weaker 
  races 
  farther 
  and 
  

   farther 
  from 
  the 
  older 
  settlements 
  of 
  man- 
  

   kind.
