  The 
  preceding 
  statements 
  of 
  area 
  above 
  certain 
  elevations 
  are 
  

   rather 
  general 
  — 
  time 
  has 
  not 
  been 
  taken 
  for 
  detailed 
  estimates. 
  

   There 
  are, 
  however, 
  from 
  8000 
  to 
  10,000 
  square 
  miles 
  available. 
  

   From 
  all 
  these 
  centers, 
  Tin-contaminated 
  streams 
  of 
  great 
  natural 
  

   purity 
  issue. 
  There 
  are 
  also 
  several 
  minor 
  points 
  throughout 
  the 
  

   State 
  for 
  which 
  the 
  same 
  statement 
  is 
  true. 
  

  

  The 
  Adirondack 
  water 
  center 
  is 
  separated 
  from 
  the 
  'Catskill 
  by 
  

   the 
  valley 
  of 
  the 
  Mohawk 
  river, 
  which 
  receives 
  drainage 
  from 
  

   both 
  — 
  the 
  East 
  and 
  West 
  Canada 
  creeks 
  and 
  other 
  tributaries 
  of 
  

   the 
  Mohawk 
  on 
  the 
  north 
  side 
  of 
  the 
  valley 
  rising 
  in 
  the 
  Adiron- 
  

   dack 
  center, 
  while 
  the 
  Schoharie 
  creek 
  on 
  the 
  south 
  side 
  is 
  an 
  

   important 
  tributary 
  from 
  the 
  Catskill 
  center. 
  

  

  In 
  addition 
  to 
  the 
  Mohawk 
  river, 
  other 
  important 
  streams 
  of 
  

   the 
  State 
  issuing 
  from 
  the 
  Adirondack 
  center 
  are 
  the 
  Black, 
  Oswe-

  Hudson 
  rivers. 
  

  

  From 
  Catskill 
  center, 
  in 
  addition 
  to 
  Schoharie 
  creek, 
  we 
  find 
  

   issuing 
  the 
  headwaters 
  of 
  the 
  Susquehanna, 
  Delaware 
  and 
  Wall- 
  

   kill 
  rivers 
  and 
  Esopus

  The 
  Allegheny

  supplies 
  the 
  headwaters 
  of 
  Cattaraugus 
  

   creek, 
  Genesee, 
  Chemung, 
  Canisteo, 
  Tioga, 
  west 
  branch 
  of 
  the 
  Sus- 
  

   quehanna 
  and 
  Allegheny 
  rivers.

  Generally 
  speaking 
  the 
  main 
  river 
  valleys 
  of 
  New 
  York 
  are 
  at 
  

   comparatively 
  low 
  elevations, 
  as 
  may 
  be 
  sufficiently 
  appreciated 
  

   by 
  considering 
  the 
  elevation 
  of 
  a 
  few 
  of 
  the 
  principal 
  streams.

  ; 
  main 
  Susquehanna

  the 
  main 
  Delaware; 
  main 
  Allegheny
