  On 
  the 
  eastern 
  end 
  the 
  hematites 
  can 
  be 
  traced 
  as 
  far 
  as 
  the 
  

   Oneida-Herkimer 
  county 
  border 
  without 
  any 
  noticeable 
  changes 
  

   of 
  character. 
  After 
  passing 
  that 
  line 
  their 
  thickness 
  falls 
  off 
  

   quite 
  rapidly. 
  At 
  the 
  outcrop 
  west 
  of 
  Frankfort 
  hill, 
  in 
  the 
  

   town 
  of 
  Frankfort, 
  Herkimer 
  co., 
  the 
  oolitic 
  bed 
  measures 
  only 
  10 
  

   inches, 
  which 
  is 
  about 
  one 
  third 
  the 
  amount 
  represented 
  at 
  Clinton, 
  

  

  9 
  miles 
  west. 
  The 
  red 
  flux 
  bed 
  on 
  the 
  other 
  hand 
  is 
  still 
  fairly 
  

   well 
  maintained 
  as 
  regards 
  thickness, 
  showing 
  about 
  40 
  inches. 
  

   Following 
  the 
  strike 
  to 
  the 
  southeast 
  across 
  southern 
  Herkimer 
  

   county, 
  the 
  beds 
  appear 
  to 
  give 
  out 
  within 
  a 
  short 
  dis- 
  

   tance, 
  for 
  they 
  can 
  not 
  be 
  identified 
  in 
  the 
  outcrops, 
  or 
  else 
  they 
  

   shade 
  off 
  into 
  a 
  ferruginous 
  sandstone 
  that 
  is 
  much 
  different 
  

   from 
  the 
  normal 
  ore 
  varieties. 
  In 
  the 
  exposures 
  along 
  the 
  hills 
  

   south 
  of 
  the 
  Mohawk 
  river, 
  between 
  Frankfort 
  and 
  Herkimer, 
  

   neither 
  the 
  oolitic 
  nor 
  the 
  red 
  flux 
  bed 
  can 
  be 
  seen, 
  but 
  there 
  are 
  

  

  10 
  feet 
  or 
  more 
  of 
  deep 
  red 
  sandstone 
  heavily 
  charged 
  with 
  

   hematite. 
  The 
  latter 
  functions 
  as 
  cement 
  to 
  the 
  quartz 
  grains, 
  

   but 
  does 
  not 
  encrust 
  them. 
  The 
  iron 
  content 
  of 
  the 
  sandstone 
  

   may 
  be 
  placed 
  at 
  about 
  10^. 
  The 
  entire 
  Clinton 
  disappears, 
  so 
  

   far 
  as 
  surface 
  indications 
  are 
  concerned, 
  near 
  the 
  eastern 
  border 
  

   of 
  Herkimer 
  county. 
  

  

  The 
  ore 
  seams 
  thus 
  attain 
  their 
  fullest 
  development 
  in 
  re- 
  

   spect 
  to 
  thickness 
  within 
  the 
  stretch 
  from 
  eastern 
  Oneida 
  to 
  

   western 
  Wayne 
  county. 
  Beyond 
  these 
  limits 
  they 
  have 
  little 
  

   economic 
  importance 
  for 
  the 
  present, 
  at 
  least, 
  and 
  their 
  explora- 
  

   tion 
  is 
  not 
  of 
  immediate 
  concern. 
  

  

  The 
  information 
  gained 
  from 
  the 
  test 
  drilling, 
  described 
  else- 
  

   where 
  in 
  this 
  report, 
  serves 
  to 
  show 
  the 
  distribution 
  of 
  the 
  more 
  

   valuable 
  ore 
  bodies 
  with 
  some 
  precision. 
  It 
  has 
  been 
  found 
  

   that 
  the 
  ore 
  is 
  mainly 
  gathered 
  into 
  four 
  areas 
  which 
  succeed 
  

   each 
  other 
  along 
  the 
  outcrop, 
  after 
  longer 
  or 
  shorter 
  intervals 
  

   that 
  are 
  characterized 
  by 
  thin 
  seams, 
  much 
  below 
  the 
  average, 
  

   or 
  by 
  their 
  almost 
  complete 
  disappearance. 
  There 
  is 
  a 
  possi- 
  

   bility 
  of 
  one 
  or 
  two 
  additional 
  areas 
  being 
  present 
  that 
  have 
  

   escaped 
  notice 
  by 
  reason 
  of 
  the 
  wide 
  spacing 
  of 
  the 
  holes, 
  but 
  

   they 
  must 
  be 
  of 
  minor 
  extent 
  compared 
  with 
  the 
  others. 
  

  

  The 
  area 
  which 
  centers 
  about 
  Clinton, 
  Oneida 
  co., 
  has 
  been 
  

   the 
  principal 
  source 
  of 
  the 
  ore 
  in 
  the 
  past. 
  There 
  are 
  two 
  seams 
  

   here, 
  an 
  upper 
  of 
  fossil 
  character 
  called 
  the 
  red 
  flux 
  bed 
  and 
  

   a 
  lower 
  oolitic 
  bed 
  that 
  is 
  sometimes 
  split 
  into 
  two 
  portions 
  

   by 
  a 
  layer 
  of 
  barren 
  rock. 
  The 
  fossil 
  ore 
  is 
  too 
  lean 
  to 
  be 
  used
