  Conclusion 
  

  

  The 
  limitations 
  of 
  time 
  and 
  appropriation 
  for 
  this 
  investigation 
  

   have 
  prevented 
  the 
  extension 
  of 
  the 
  work 
  to 
  the 
  degree 
  origin- 
  

   ally 
  contemplated. 
  The 
  most 
  important 
  unfinished 
  part 
  is 
  the 
  

   correlation 
  of 
  the 
  oil-producing 
  sands 
  of 
  southern 
  New 
  York 
  

   with 
  the 
  already 
  recognized 
  petroleum 
  horizons 
  in 
  Pennsylvania. 
  

  

  Aside 
  from 
  the 
  difficulty 
  in 
  obtaining 
  correct 
  records, 
  referred 
  

   to 
  elsewhere, 
  the 
  main 
  obstacle 
  to 
  this 
  correlation 
  lies 
  in 
  the 
  

   absence 
  of 
  one 
  or 
  more 
  well 
  known 
  horizons 
  of 
  reference 
  from 
  

   which 
  measurements 
  can 
  be 
  made. 
  For 
  illustration, 
  there 
  is 
  in 
  

   southern 
  Cattaraugus 
  co., 
  no 
  rock 
  so 
  easily 
  recognized 
  as 
  are 
  the 
  

   Corniferous 
  and 
  Niagara 
  limestones 
  which 
  furnish 
  such 
  reliable 
  

   guides 
  to 
  the 
  well-borer 
  and 
  geologist 
  in 
  northern 
  and 
  central 
  

   New 
  York. 
  

  

  Regarding 
  the 
  conglomerates 
  and 
  coarse 
  sands 
  which 
  have 
  

   served 
  the 
  purpose 
  of 
  reference 
  in 
  this 
  region, 
  there 
  is 
  still 
  much 
  

   confusion 
  and 
  in 
  some 
  localities 
  at 
  least, 
  their 
  identity 
  is 
  yet 
  in 
  

   question. 
  As 
  a 
  consequence 
  the 
  measurements 
  made 
  from 
  an 
  

   uncertain 
  horizon 
  are 
  in 
  themselves 
  uncertain 
  and 
  unreliable. 
  

   The 
  aneroid 
  has 
  not 
  in 
  my 
  hands 
  proved 
  sufficiently 
  accurate 
  to 
  

   warrant 
  me 
  in 
  deciding 
  that 
  a 
  doubtful 
  outcrop 
  was 
  Olean 
  or 
  

   Subolean, 
  specially 
  in 
  a 
  region 
  where, 
  as 
  in 
  the 
  case 
  north 
  of 
  

   Bradford, 
  flexures 
  are 
  known 
  to 
  exist. 
  

  

  It 
  appears 
  to 
  me, 
  therefore, 
  that 
  this 
  work 
  needs 
  for 
  its 
  success- 
  

   ful 
  completion, 
  1) 
  a 
  careful 
  study 
  of 
  the 
  surface 
  geology 
  of 
  Cat- 
  

   taraugus 
  and 
  Chautauqua 
  counties 
  for 
  the 
  purpose 
  of 
  mapping 
  

   the 
  outcrops 
  of 
  the 
  several 
  conglomerates; 
  and 
  2) 
  the 
  accurate 
  

   determination, 
  by 
  level, 
  of 
  the 
  altitude 
  of 
  each 
  conglomerate 
  at 
  

   several 
  points. 
  This 
  investigation 
  would 
  require 
  a 
  month 
  or 
  

   more 
  of 
  field 
  work, 
  after 
  which 
  the 
  solution 
  of 
  the 
  problem 
  would 
  

   be 
  comparatively 
  simple. 
  Incidentally 
  light 
  would 
  be 
  thrown 
  

   upon 
  the 
  question 
  of 
  whether 
  the 
  sands 
  are 
  merely 
  local 
  lenti- 
  

   cular 
  deposits 
  or 
  widespread 
  in 
  extent.
