  ■ 
  

  

  The 
  following 
  basis 
  was 
  adopted 
  for 
  type 
  differentiation 
  : 
  

  

  Hardwoods 
  : 
  Includes 
  both 
  the 
  northern 
  and 
  sprout 
  hardwoods 
  

   where 
  the 
  softwoods 
  have 
  been 
  cut 
  out 
  to 
  such 
  an 
  extent 
  as 
  to 
  be 
  

   negligible. 
  May 
  contain 
  spruce 
  and 
  pine 
  up 
  to 
  twenty-five 
  per 
  cent, 
  

   of 
  stand 
  (trees 
  per 
  acre).

  with 
  a 
  spruce 
  

   understory.

  previous 
  

   to 
  this 
  time 
  are 
  now 
  covered 
  with 
  poplar 
  and 
  are 
  classed 
  with 
  that 
  

   type. 
  

  

  Agricultural

  less 
  than 
  640 
  acre 
  tracts 
  considered. 
  

  

  RELATION 
  OF 
  TYPE 
  TO 
  SITUATION 
  

  

  The 
  area 
  under 
  consideration 
  can 
  be 
  roughly 
  divided 
  into 
  three 
  

   regions 
  : 
  

  

  First: 
  The 
  spruce 
  region, 
  lying 
  west 
  of 
  the 
  Hudson 
  river. 
  

  

  Second 
  : 
  The 
  pine 
  region, 
  lying 
  between 
  the 
  Hudson 
  and 
  Schroon 
  

   rivers. 
  

  

  Third: 
  The 
  hardwood 
  region, 
  lying 
  east 
  of 
  the 
  Schroon 
  river. 
  

  

  In 
  each 
  case, 
  the 
  name 
  of 
  the 
  region 
  indicates 
  the 
  kind 
  of 
  forest 
  

   that 
  would 
  grow 
  there 
  were 
  it 
  not 
  for 
  disturbing 
  factors. 
  Within 
  

   these 
  broadly 
  defined 
  regions 
  there 
  are 
  certain 
  exceptions. 
  

  

  The 
  hardwoods 
  are 
  found 
  wherever 
  the 
  soil 
  is 
  of 
  fair 
  depth 
  and 
  

   quality 
  throughout 
  all 
  three 
  of 
  these 
  regions.
