  is 
  

   in 
  reality 
  a 
  subdivision 
  of 
  the

  Lawrence, 
  but 
  made 
  separate 
  

   here 
  merely 
  for 
  convenience 
  in 
  discussing

  of

  river, 
  one 
  of 
  the

  in 
  Connecticut, 
  flows 
  out

  to 
  the

  while 
  the 
  

   headwaters 
  of

  county, 
  flow 
  from 
  New 
  

   York 
  into 
  New 
  Jersey. 
  These 
  latter 
  are 
  of 
  possible 
  future 
  im- 
  

   portance 
  by 
  reason 
  of

  necessity 
  of 
  water 
  for 
  the 
  supply

  line 
  

   approaches 
  within 
  a 
  few 
  miles 
  of 
  Lake 
  Erie, 
  but 
  at 
  an 
  elevation 
  

   of 
  several 
  hundred 
  feet 
  above, 
  and 
  as 
  a 
  consequence 
  the 
  streams 
  

   are 
  short 
  and 
  rapid. 
  A 
  small 
  amount 
  of 
  power 
  is 
  developed 
  on 
  

   Chautauqua 
  creek 
  at 
  Westfield, 
  and 
  on
