  INTRODUCTORY 
  NOTE 
  

  

  The 
  great 
  importance 
  of 
  water 
  as 
  an 
  economic 
  mineral 
  is 
  

   becoming 
  daily 
  more 
  and 
  more 
  fully 
  appreciated 
  by 
  the 
  commer- 
  

   cial 
  public, 
  though 
  its 
  recognition 
  as 
  a 
  source 
  of 
  power 
  in 
  

   engineering 
  enterprise 
  is 
  a 
  matter 
  of 
  great 
  antiquity. 
  It 
  there- 
  

   fore 
  seemed 
  appropriate 
  that 
  the 
  geologic 
  work 
  of 
  the 
  New 
  York 
  

   State 
  Museum 
  should 
  make 
  some 
  contribution 
  to 
  the 
  sum 
  total 
  

   of 
  public 
  knowledge 
  on 
  this 
  matter. 
  Accordingly 
  my 
  predecessor 
  

   in 
  office, 
  Dr 
  Frederick 
  J. 
  H. 
  Merrill, 
  invited 
  Mr 
  George 
  W. 
  Rafter 
  

   to 
  write 
  a 
  general 
  discussion 
  of 
  this 
  important 
  subject 
  in 
  its 
  rela- 
  

   tions 
  to 
  New 
  York. 
  As 
  a 
  result 
  the 
  following 
  report 
  is 
  offered 
  to 
  

   the 
  citizens 
  of 
  the 
  State, 
  with 
  the 
  feeling 
  that 
  Mr 
  Rafter's 
  wide 
  

   repute 
  as 
  a 
  specialist 
  in 
  this 
  branch 
  will 
  make 
  this 
  publication 
  a 
  

   communication 
  of 
  much 
  value 
  to 
  engineering 
  and 
  to 
  commerce.
