  PRIMEVAL 
  MAN. 
  

  

  would 
  always 
  be 
  the 
  weaker 
  tribes 
  who 
  would 
  

   be 
  driven 
  from 
  the 
  ground 
  which 
  had 
  become 
  

   overstocked, 
  and 
  as 
  the 
  lands 
  to 
  which 
  they 
  

   went 
  forth 
  were 
  less 
  and 
  less 
  hospitable 
  in 
  

   climate 
  and 
  productions, 
  the 
  struggle 
  for 
  

   life 
  would 
  be 
  always 
  harder. 
  And 
  so 
  it 
  

   always 
  happens 
  in 
  the 
  natural 
  and 
  necessary 
  

   course 
  of 
  things, 
  that 
  the 
  races 
  which 
  were 
  

   driven 
  farthest 
  would 
  be 
  the 
  rudest 
  — 
  the 
  

   most 
  engrossed 
  in 
  the 
  pursuits 
  of 
  mere 
  

   animal 
  existence. 
  

  

  And 
  now, 
  does 
  not 
  this 
  key 
  of 
  principle 
  

   fit 
  into 
  and 
  explain 
  all 
  the 
  facts 
  ? 
  Do 
  they 
  

   not 
  seem 
  in 
  the 
  light 
  of 
  that 
  explanation 
  to 
  

   take 
  form 
  and 
  order? 
  Is 
  it 
  not 
  true 
  that 
  the 
  

   lowest 
  and 
  rudest 
  tribes 
  in 
  the 
  population 
  

   of 
  the 
  globe 
  have 
  been 
  found 
  at 
  the 
  farthest
