  INTBODUCTKXN

  was 
  to 
  devise 
  ready 
  means 
  of 
  getting 
  rid 
  of 
  the 
  trees 
  which 
  

   covered 
  the 
  hind 
  ( 
  lig. 
  lU"). 
  A 
  large 
  part 
  of 
  the 
  terntorv 
  ex- 
  

   tending 
  east 
  and 
  southeast 
  from 
  the 
  (ireat 
  Plains 
  region 
  to 
  

   the 
  Atlantic 
  and 
  the 
  Gulf 
  of 
  Mexico 
  was 
  forest-covered. 
  

  

  Now 
  that 
  tliese 
  im- 
  

   mense 
  primeval 
  fore-is 
  

   have 
  been 
  dest 
  roved, 
  

  

  never 
  to 
  be 
  reneucd 
  

   in 
  their 
  original 
  luxu- 
  

   riance, 
  we 
  are 
  coining 
  

   to 
  realize 
  that 
  in 
  re- 
  

   moving 
  them 
  the 
  early 
  

   settlers 
  put 
  an 
  end 
  to 
  

   an 
  almost 
  unlimited 
  

   source 
  of 
  income, 
  and 
  

   greatly 
  injured 
  the 
  soil 
  

   and 
  climate 
  of 
  larcre 
  

  

  O 
  

  

  areas. 
  Some 
  of 
  the 
  land 
  

   had 
  to 
  he 
  cleared 
  in 
  

   order 
  to 
  make 
  tillable 
  

   lields 
  to 
  grow 
  bread- 
  

   si 
  u 
  t't's 
  for 
  the 
  earliest 
  

   settlers, 
  but 
  it 
  is 
  unfor- 
  

   tunate 
  that 
  the 
  clear- 
  

   ing 
  process 
  was 
  so 
  

   well-nigh 
  universal.

  Pure 
  and 
  mixed 
  

   forests. 
  Some 
  forests 
  

   are 
  composed 
  almost 
  

   entirely 
  of 
  a, 
  single 
  kind 
  of 
  tree, 
  like 
  the 
  long-leaf 
  pine 
  

   growth 
  of 
  ligure 
  220. 
  A 
  t'e\v 
  of 
  the 
  hard-wood 
  lives, 
  as 
  the 
  

   birches, 
  oaks, 
  and 
  maples, 
  are 
  not 
  infrequently 
  found 
  growing 
  

   nearly 
  unmixed 
  with 
  other 
  trees. 
  More 
  frequently, 
  however, 
  

   two 
  or 
  more 
  kinds 
  of 
  conifers 
  grow 
  intermixed 
  in 
  the 
  same 
  

   forest, 
  and 
  the 
  hard-wood 
  lives 
  are 
  still 
  more 
  likely 
  to 
  occur 
  

   with 
  se\eral 
  kinds 
  associated. 
  Thus 
  we 
  hud 
  in 
  the 
  same
