  and 
  that 
  forestation 
  should 
  be 
  carried 
  on 
  within 
  the 
  limits 
  fixed 
  

   by 
  such 
  a 
  commission. 
  

  

  Examining 
  the 
  hypsometric 
  map 
  accompanying 
  this 
  report, 
  we 
  

   observe 
  that 
  there 
  are 
  six 
  high 
  points 
  which 
  may 
  be 
  denominated 
  

   water 
  centers, 
  which 
  are 
  referred 
  to 
  on 
  page 
  40. 
  

  

  The 
  largest 
  and 
  most 
  important 
  of 
  these 
  is 
  the 
  elevated 
  region 
  

   known 
  as 
  the 
  Adirondack 
  mountains, 
  or 
  for 
  present 
  purposes, 
  the 
  

   Adirondack 
  center, 
  the 
  highest 
  peaks 
  of 
  which 
  rise 
  to 
  an 
  altitude 
  

   of 
  over 
  5000 
  feet, 
  and 
  there 
  are 
  about 
  4000 
  square 
  miles 
  at 
  an 
  ele- 
  

   vation 
  of 
  2000 
  feet 
  and 
  over. 
  This 
  region 
  has 
  a 
  population 
  of 
  

   from 
  8 
  to 
  10 
  to 
  the 
  square 
  mile. 
  The 
  population 
  of 
  the 
  balance 
  of 
  

   the 
  water 
  centers 
  is^ 
  somewhat 
  greater 
  than 
  this, 
  but 
  in 
  none 
  of 
  

   them 
  is 
  it 
  beyond 
  the 
  limit 
  of 
  a 
  pure 
  water 
  supply, 
  with 
  proper 
  

   precaution. 
  The 
  principal 
  lakes 
  lie 
  at 
  an 
  elevation 
  of 
  from 
  1500 
  

   to 
  2000 
  feet.

  The 
  second, 
  or 
  Catskill 
  center, 
  includes 
  the 
  Catskill 
  mountains 
  

   in 
  the 
  southeastern 
  part 
  of 
  the 
  State, 
  where 
  the 
  highest 
  points 
  

   rise 
  to 
  an 
  altitude 
  of 
  over 
  4000 
  feet 
  and 
  there 
  is 
  an 
  area 
  of 
  about 
  

   1000 
  square 
  miles 
  at 
  an 
  elevation 
  of 
  2000 
  feet 
  and 
  over. 
  

  

  The 
  third, 
  which 
  may 
  be 
  called 
  the 
  Allegheny 
  center, 
  is 
  the 
  ele- 
  

   vated 
  region 
  in 
  the 
  southwestern 
  part 
  of 
  the 
  State 
  in 
  Cattaraugus, 
  

   Allegany 
  and 
  Steuben 
  counties, 
  where 
  the 
  highest 
  points 
  are 
  at 
  an 
  

   elevation 
  of 
  over 
  2000 
  feet 
  and 
  there 
  is 
  an 
  area 
  of 
  from 
  500 
  to 
  800 
  

   square 
  miles 
  at 
  an 
  elevation 
  of 
  over 
  1500 
  feet. 
  

  

  The 
  fourth, 
  or 
  Rensselaer 
  center, 
  lies 
  east 
  of 
  Troy, 
  Albany 
  and 
  

   Poughkeepsie, 
  and 
  its 
  highest 
  altitudes 
  are 
  over 
  2000 
  feet, 
  while 
  

   there 
  are 
  from 
  1000 
  to 
  1200 
  square 
  miles 
  at 
  an 
  elevation 
  of 
  over 
  

   600 
  feet. 
  Since 
  the 
  distance 
  from 
  the 
  Hudson 
  river 
  is 
  short, 
  this 
  

   elevation 
  is 
  enough 
  to 
  supply 
  the 
  cities 
  and 
  towns 
  naturally 
  

   tributary. 
  

  

  The 
  fifth, 
  or 
  Chenango 
  center, 
  is 
  west 
  of 
  the 
  Catskill 
  mountains, 
  

   with 
  an 
  extreme 
  elevation 
  of 
  over 
  1800 
  feet, 
  and 
  there 
  are 
  from 
  

   1200 
  to 
  2000 
  square 
  miles 
  at 
  an 
  elevation 
  exceeding 
  1200 
  feet. 
  

  

  The 
  sixth, 
  or 
  Lowville 
  center, 
  is 
  to 
  the 
  north 
  of 
  Oneida 
  lake, 
  

   with 
  an 
  extreme 
  elevation 
  of 
  from 
  1800 
  to 
  2000 
  feet, 
  and 
  there 
  are 
  

   from 
  400 
  to 
  600 
  square 
  miles 
  at 
  an 
  elevation 
  of 
  over 
  1200 
  feet. 
  The 
  

   issuing 
  streams 
  are 
  lower 
  than 
  the 
  foregoing, 
  but 
  still 
  high 
  enough 
  

   to 
  insure 
  gravity 
  supplies.
