  This 
  paper 
  contains 
  a 
  synopsis 
  of 
  the 
  results 
  of 
  an 
  investigation 
  

   begun 
  in 
  1883 
  and 
  carried 
  on 
  at 
  personal 
  expense 
  till 
  1890, 
  from 
  

   which 
  time 
  till 
  1893, 
  small 
  sums 
  were 
  afforded 
  from 
  the 
  funds 
  of 
  the 
  

   New 
  York 
  State 
  Museum 
  for 
  continuing 
  the 
  field 
  work. 
  In 
  1895, 
  

   there 
  being 
  no 
  museum 
  funds 
  available 
  for 
  this 
  purpose, 
  the 
  Director 
  

   of 
  the 
  United 
  States 
  Geological 
  Survey 
  contributed 
  $200 
  for 
  com- 
  

   pleting 
  the 
  Precambrian 
  and 
  Palaeozoic 
  geology 
  of 
  the 
  Harlem 
  

   sheet 
  of 
  the 
  United 
  States 
  topographic 
  atlas, 
  embracing 
  the 
  region 
  

   about 
  New 
  York 
  city. 
  A 
  copy 
  of 
  this 
  Geologic 
  map 
  and 
  of 
  the 
  

   descriptive 
  text 
  were 
  furnished 
  to 
  Director 
  Walcott 
  and 
  will 
  be 
  

   incorporated 
  in 
  the 
  New 
  York 
  FoHo 
  which 
  is 
  soon 
  to 
  be 
  published. 
  

  

  The 
  preliminary 
  results 
  of 
  the 
  general 
  investigation 
  were 
  pub- 
  

   lished 
  in

  American 
  Journal 
  of 
  Science,

  The 
  geologic 
  mapping 
  of 
  the 
  whole 
  area 
  east 
  of 
  the 
  Hudson 
  

   in 
  New 
  York 
  was 
  published 
  in

  map 
  of 
  

   New 
  York, 
  by

  The 
  geology 
  of 
  Westchester 
  county 
  is 
  also 
  shown 
  on 
  a 
  scale 
  of 
  

   four 
  miles 
  to 
  the 
  inch, 
  in 
  the 
  Geologic 
  Map 
  of 
  a 
  Part 
  of 
  Southeastern 
  

   New 
  York, 
  by 
  F. 
  J. 
  H. 
  Merrill, 
  pubHshed 
  in 
  Bulletin 
  No. 
  15, 
  of 
  the 
  

   New

  In 
  completing 
  the 
  work 
  for 
  the 
  Harlem 
  sheet 
  of 
  the 
  New 
  York 
  

   folio 
  the 
  writer 
  had 
  an 
  opportunity 
  to 
  review 
  the 
  ground 
  in 
  com- 
  

  

  •The 
  draft 
  for 
  this 
  publication 
  was 
  prepared 
  at 
  the 
  request 
  of 
  Prof. 
  Hall 
  in 
  i8g3 
  and 
  was 
  not 
  

   -revised 
  before 
  engraving, 
  so 
  that 
  it 
  differs 
  slightly 
  from 
  the 
  map 
  of 
  Southeastern 
  New 
  York 
  

   ^which 
  contains 
  the 
  results 
  of 
  additional 
  field 
  work.
