  geology 
  was 
  also 
  represented 
  in 
  the 
  decade 
  by 
  H. 
  L. 
  Fairchild's 
  

   maps 
  on 
  the 
  glacial 
  geology 
  of 
  western 
  New 
  York. 
  Since 
  1900 
  

   the 
  progress 
  in 
  mapping 
  the 
  geology 
  has 
  proceeded 
  rapidly 
  along 
  

   all 
  lines, 
  numerous 
  areal, 
  economic, 
  stratigraphic, 
  paleogeographic 
  

   and 
  pleistocene 
  maps 
  all 
  having 
  been 
  published. 
  The 
  main 
  efforts, 
  

   at 
  present, 
  are 
  toward 
  a 
  complete 
  geologic 
  map 
  of 
  the 
  State 
  using 
  

   the 
  quadrangles 
  surveyed 
  by 
  the 
  United 
  States 
  Geological 
  Survey 
  as 
  

   a 
  base, 
  and 
  a 
  number 
  of 
  such 
  quadrangles 
  have 
  been 
  published. 
  In 
  

   this 
  way, 
  piece 
  by 
  piece, 
  like 
  the 
  forming 
  of 
  a 
  mosaic 
  picture, 
  the 
  

   detailed 
  geology 
  of 
  the 
  State 
  is 
  being 
  worked 
  out. 
  

  

  The 
  last 
  complete 
  map 
  of 
  the 
  State 
  was 
  the 
  1901 
  map 
  by 
  F. 
  J. 
  H. 
  

   Merrill 
  corrected 
  up 
  to 
  date 
  from 
  the 
  Hall-McGee 
  map 
  of 
  1894. 
  

   This 
  represents 
  the 
  results 
  of 
  all 
  the 
  geologic 
  work 
  done 
  previous 
  

   to 
  that 
  time 
  and 
  is 
  a 
  fitting 
  map 
  with 
  which 
  to 
  compare 
  the 
  earlier 
  

   efforts 
  of 
  McClure 
  and 
  Eaton. 
  

  

  We 
  have 
  now 
  reached 
  the 
  hundredth 
  anniversary 
  of 
  the 
  geologic 
  

   map 
  of 
  the 
  United 
  States 
  and 
  incidentally 
  of 
  this 
  State, 
  and 
  al- 
  

   though 
  there 
  is 
  yet 
  much 
  to 
  be 
  done, 
  the 
  work 
  from 
  now 
  on 
  must 
  

   be 
  of 
  detailed 
  character 
  and 
  we 
  may 
  expect 
  no 
  great 
  changes 
  in 
  

   the 
  general 
  map. 
  We 
  have 
  reviewed 
  the 
  five 
  complete 
  maps: 
  the 
  

   McClure 
  1809, 
  the 
  Eaton 
  1830, 
  the 
  1842 
  map, 
  the 
  Hall 
  map 
  of 
  

   1894 
  and 
  lastly 
  the 
  Merrill 
  map 
  of 
  1901, 
  and 
  we 
  have 
  also 
  noted 
  

   the 
  smaller 
  sections 
  mapped 
  by 
  counties, 
  townships 
  and 
  even 
  

   quadrangles. 
  

  

  In 
  making 
  up 
  the 
  chronological 
  list 
  the 
  date 
  given 
  on 
  the 
  margin 
  

   indicates 
  the 
  date 
  of 
  publication, 
  and 
  does 
  not 
  represent 
  the 
  date 
  

   on 
  the 
  map 
  or 
  the 
  year 
  of 
  which 
  an 
  annual 
  report 
  is 
  a 
  review, 
  

   these 
  dates 
  where 
  given 
  having 
  been 
  inclosed 
  in 
  parentheses. 
  Under 
  

   the 
  ye.irs 
  the 
  maps 
  are 
  arranged 
  alphabetically 
  by 
  authors. 
  

  

  The 
  author 
  has 
  aimed 
  at 
  getting 
  together 
  all 
  geologic 
  maps 
  deal- 
  

   ing 
  with 
  New 
  York 
  State 
  geology. 
  It 
  is 
  realized 
  that 
  some 
  have 
  

   probably 
  been 
  overlooked, 
  but 
  all 
  of 
  importance 
  are 
  probably 
  in- 
  

   cluded. 
  Many 
  maps 
  used 
  in 
  textbooks 
  and 
  other 
  such 
  literature, 
  

   which 
  are 
  evidently 
  but 
  copies 
  of 
  some 
  maps 
  listed 
  here, 
  have 
  pur- 
  

   posely 
  been 
  omitted. 
  Maps 
  of 
  the 
  United 
  States 
  and 
  other 
  large 
  

   maps 
  simply 
  including 
  New 
  York 
  State 
  as 
  a 
  portion 
  of 
  a 
  larger 
  

   area 
  have 
  been 
  listed 
  but 
  sparingly, 
  only 
  the 
  more 
  interesting 
  of 
  

   such 
  having 
  been 
  examined. 
  Following 
  the 
  chronologic 
  list 
  is 
  an 
  

   index 
  by 
  means 
  of 
  which, 
  it 
  is 
  hoped, 
  the 
  maps 
  dealing 
  with 
  a 
  

   certain 
  section 
  of 
  the 
  State 
  or 
  maps 
  by 
  certain 
  authors 
  can 
  readily 
  

   be 
  located 
  in 
  the 
  chronologic 
  list.
