  PEEFACE 
  

  

  The 
  following 
  report 
  by 
  Prof. 
  Woodworth 
  on 
  the 
  results 
  of 
  field 
  

   work 
  in 
  western 
  Long 
  Island 
  is 
  in 
  continuation 
  of 
  an 
  investiga- 
  

   tion 
  of 
  the 
  quaternary 
  formations 
  of 
  Long 
  Island 
  and 
  the 
  Quater- 
  

   nary 
  history 
  of 
  the 
  Hudson 
  river 
  valley 
  begun 
  in 
  1883 
  by 
  the 
  

   present 
  state 
  geologist. 
  

  

  The 
  great 
  development 
  of 
  the 
  branch 
  of 
  Quaternary 
  investigation 
  

   makes 
  it 
  now 
  possible 
  to 
  seek 
  j)ositive 
  proof 
  where 
  formerly 
  only 
  

   broad 
  inferences 
  could 
  be 
  drawn. 
  

  

  Prof. 
  Woodworth's 
  work 
  will 
  include 
  the 
  Hudson 
  and 
  Cham- 
  

   plain 
  valleys 
  and 
  the 
  drainage 
  basins 
  tributary 
  to 
  them 
  and 
  his 
  

   results 
  may 
  be 
  expected 
  to 
  contribute 
  an 
  important 
  chapter 
  to 
  

   American 
  Quaternary 
  history.
