  contributed 
  many 
  facts 
  relating 
  to 
  ore 
  localities 
  and 
  mines 
  in 
  

   Oneida 
  county, 
  and 
  of 
  Mr 
  H. 
  M. 
  Selleck 
  and 
  Mr 
  Freeman 
  Pintler 
  

   of 
  Ontario, 
  who 
  furnished 
  much 
  information 
  about 
  the 
  ores 
  of 
  

   Wayne 
  county. 
  The 
  line 
  drawings 
  accompanying 
  the 
  report 
  have 
  

   been 
  made 
  by 
  Mr

  PREVIOUS 
  STUDIES 
  

  

  The 
  researches 
  of 
  Hall 
  and 
  Vanuxem 
  in 
  connection 
  with 
  the 
  

   first 
  Geological 
  Survey 
  of 
  New 
  York 
  State 
  have 
  been 
  the 
  source 
  

   of 
  most 
  of 
  our 
  knowledge 
  concerning 
  the 
  Clinton 
  formation. 
  

   The 
  descriptions 
  of 
  its 
  bounds 
  and 
  relations, 
  as 
  set 
  forth 
  in 
  their 
  

   final 
  reports 
  of 
  1842-43, 
  have 
  undergone 
  no 
  essential 
  amend- 
  

   ment 
  to 
  this 
  day 
  and 
  are' 
  still 
  standard 
  for 
  the 
  recognition 
  and 
  

   comparison 
  of 
  the 
  different 
  Clinton 
  occurrences 
  elsewhere. 
  

  

  Previous 
  to 
  their 
  investigations, 
  Amos 
  Eaton 
  had 
  given 
  a 
  

   brief 
  account 
  of 
  the 
  ores 
  and 
  associated 
  beds 
  in 
  his 
  monograph, 
  

   A 
  Geological 
  and 
  Agricultural 
  Survey 
  of 
  the 
  District 
  adjoining 
  the 
  

   Erie 
  Canal. 
  Eaton 
  seems 
  to 
  have 
  visited 
  the 
  outcrops 
  along 
  the 
  

   belt 
  at 
  intervals 
  from 
  Herkimer 
  county 
  to 
  the 
  Niagara 
  river. 
  

   The 
  hematites 
  are 
  placed 
  in 
  the 
  class 
  of 
  " 
  secondary 
  ferriferous 
  

   rocks," 
  which 
  are 
  stated 
  to 
  consist 
  principally 
  of 
  slate 
  and 
  sand- 
  

   stone. 
  It 
  is 
  not 
  always 
  possible 
  to 
  recognize 
  the 
  various 
  mem- 
  

   bers 
  referred 
  to 
  by 
  Eaton, 
  though 
  there 
  is 
  little 
  doubt 
  that 
  the 
  

   class 
  includes 
  parts 
  of 
  the 
  Medina 
  and 
  Rochester 
  formations, 
  

   as 
  now 
  understood, 
  in 
  addition 
  to 
  the 
  Clinton 
  beds. 
  

  

  Vanuxem, 
  whose 
  field 
  of 
  work 
  was 
  in 
  the 
  central 
  part 
  of 
  the 
  

   State, 
  first 
  described 
  the 
  Clinton 
  and 
  Niagara 
  representatives 
  

   under 
  a 
  single 
  group 
  which 
  he 
  called 
  Protean. 
  It 
  was 
  later 
  

   found 
  that 
  the 
  upper 
  and 
  lower 
  members 
  were 
  of 
  unequal 
  dis- 
  

   tribution, 
  the 
  latter 
  having 
  their 
  strongest 
  development 
  in 
  the 
  

   eastern 
  section, 
  while 
  the 
  former 
  were 
  predominant 
  in 
  the 
  west. 
  

   The 
  group 
  accordingly 
  was 
  subdivided. 
  The 
  name 
  Clinton 
  was 
  

   given 
  to 
  the 
  lower 
  part, 
  from 
  the 
  village 
  of 
  Clinton, 
  Oneida 
  

   co., 
  and 
  as 
  a 
  " 
  tribute 
  to 
  one 
  who 
  spared 
  no 
  effort 
  to 
  extend 
  a 
  

   knowledge 
  of 
  science 
  and 
  to 
  add 
  to 
  its 
  acquisitions." 
  The 
  out- 
  

   crop 
  of 
  the 
  strata 
  was 
  traced 
  by 
  Vanuxem 
  as 
  far 
  west 
  as 
  Cayuga 
  

   county. 
  

  

  In 
  the 
  final 
  report 
  by 
  James 
  Hall, 
  covering 
  the 
  western 
  section 
  

   of 
  the 
  Clinton, 
  the 
  following 
  subdivisions 
  are 
  recognized, 
  in 
  as- 
  

   cending 
  order: 
  1 
  Lower 
  green 
  shale; 
  2 
  Oolitic 
  or 
  lenticular 
  

   iron 
  ore; 
  3 
  Pentamerus 
  limestone; 
  4 
  Second 
  green 
  shale, 
  with
