  By 
  the 
  present 
  investigation 
  it 
  is 
  hoped 
  to 
  anticipate, 
  so 
  far 
  as 
  

   may 
  be, 
  the 
  need 
  for 
  a 
  practical 
  guide 
  to 
  the 
  development 
  of 
  these 
  

   deposits. 
  With 
  the 
  aid 
  of 
  a 
  legislative 
  appropriation, 
  specially 
  

   granted 
  for 
  the 
  purpose, 
  it 
  has 
  been 
  possible 
  to 
  perform 
  a 
  series 
  of 
  

   exploratory 
  tests 
  with 
  the 
  diamond 
  drill 
  and, 
  from 
  the 
  results 
  thus 
  

   secured, 
  to 
  gain 
  for 
  the 
  first 
  time 
  a 
  general 
  view 
  of 
  the 
  ore 
  dis- 
  

   tribution 
  over 
  a 
  considerable 
  section 
  of 
  the 
  Clinton 
  belt. 
  A 
  detailed 
  

   account 
  of 
  this 
  work 
  is 
  included 
  in 
  the 
  report. 
  

  

  The 
  resources 
  of 
  the 
  Clinton 
  formation, 
  known 
  to 
  exist 
  within 
  

   easy 
  reach 
  of 
  mining 
  operations, 
  are 
  so 
  extensive 
  that 
  they 
  seem 
  

   to 
  offer 
  a 
  promise 
  of 
  increased 
  commercial 
  importance 
  for 
  the 
  

   future. 
  The 
  principal 
  handicap 
  to 
  the 
  use 
  of 
  the 
  ores, 
  hitherto, 
  

   has 
  been 
  their 
  relatively 
  low 
  iron 
  content 
  — 
  from 
  35 
  to 
  45$. 
  

   But 
  with 
  the 
  rapidly 
  growing 
  demand 
  made 
  upon 
  other 
  eastern 
  

   mining 
  fields 
  — 
  which 
  has 
  been 
  reflected 
  by 
  a 
  steady 
  falling 
  off 
  

   in 
  the 
  quality 
  of 
  the 
  product 
  in 
  most 
  cases 
  — 
  its 
  effect 
  is 
  now 
  much 
  

   less 
  apparent 
  than 
  formerly 
  and 
  will 
  be 
  subject, 
  doubtless, 
  to 
  

   further 
  reduction. 
  A 
  factor 
  of 
  considerable 
  importance, 
  also, 
  in 
  

   this 
  connection 
  is 
  the 
  fluxing 
  nature 
  of 
  the 
  Clinton 
  ores, 
  which 
  

   counterbalances 
  to 
  an 
  appreciable 
  extent 
  their 
  deficiency 
  of 
  iron 
  

   when 
  used 
  in 
  the 
  furnace. 
  

  

  Because 
  of 
  the 
  unusual 
  interest 
  which 
  is 
  being 
  manifested 
  in 
  the 
  

   deposits, 
  it 
  has 
  been 
  deemed 
  best 
  to 
  make 
  the 
  results 
  of 
  the 
  investi- 
  

   gation 
  public 
  at 
  an 
  early 
  date. 
  To 
  that 
  end 
  some 
  matters 
  of 
  more 
  

   remote 
  economic 
  application 
  have 
  received 
  scant 
  attention 
  or 
  have 
  

   been 
  omitted 
  altogether 
  from 
  the 
  discussion, 
  though 
  they 
  might 
  

   properly 
  come 
  within 
  the 
  scope 
  of 
  the 
  report. 
  The 
  recent 
  field 
  

   work 
  and 
  exploration 
  have 
  brought 
  out 
  much 
  that 
  is 
  new 
  concern- 
  

   ing 
  Clinton 
  stratigraphy 
  and 
  shown 
  the 
  need 
  for 
  a 
  more 
  thorough 
  

   study 
  of 
  the 
  New 
  York 
  section, 
  to 
  our 
  knowledge 
  of 
  which 
  little 
  

   has 
  been 
  added 
  since 
  the 
  reports 
  of 
  Hall 
  and 
  Vanuxem. 
  The 
  rela- 
  

   tions 
  of 
  the 
  formation 
  to 
  its 
  associates, 
  particularly, 
  are 
  open 
  to 
  

   inquiry. 
  For 
  the 
  present 
  nothing 
  further 
  can 
  be 
  done 
  than 
  to 
  

   indicate 
  some 
  important 
  corrections 
  and 
  to 
  record 
  observations 
  on 
  

   which 
  such 
  restudy 
  may 
  be 
  based. 
  

  

  For 
  cooperation 
  in 
  the 
  preparation 
  of 
  the 
  report 
  it 
  is 
  desired 
  to 
  

   express 
  grateful 
  acknowledgment 
  to 
  .the 
  mining 
  and 
  development 
  

   enterprises 
  and 
  owners 
  of 
  ore 
  properties, 
  who 
  have 
  always 
  given 
  

   a 
  ready 
  response 
  to 
  inquiries 
  and 
  have 
  extended 
  many 
  other 
  courte- 
  

   sies 
  during 
  the 
  field 
  and 
  office 
  work. 
  The 
  report 
  has 
  specially 
  

   benefited 
  by 
  the 
  assistance 
  of 
  Mr 
  Charles 
  A. 
  Borst 
  of 
  Clinton, 
  who
