  NEW 
  YORK 
  STATE 
  MUSEUM 
  

  

  the 
  section 
  included 
  herewith 
  has 
  been 
  prepared. 
  A 
  notable 
  

   feature 
  shown 
  in 
  the 
  section 
  is 
  the 
  horse 
  of 
  rock 
  which 
  splits 
  the 
  ore 
  

   body 
  into 
  two 
  seams. 
  The 
  horse 
  thickens 
  to 
  the 
  northwest, 
  reduc- 
  

   ing 
  the 
  ore 
  breast 
  proportionately, 
  so 
  that 
  the 
  limit 
  of 
  profitable 
  

   working 
  was 
  soon 
  reached 
  in 
  that 
  direction. 
  On 
  the 
  southeast 
  only 
  

   the 
  hanging 
  seam 
  10 
  to 
  15 
  feet 
  thick 
  has 
  been 
  exploited. 
  

  

  The 
  Podunk 
  mine 
  on 
  a 
  parallel 
  ore 
  body 
  is 
  bottomed 
  at 
  300 
  feet. 
  

   There 
  are 
  several 
  hundred 
  feet 
  of 
  drifts 
  extending 
  horizontally 
  

   from 
  the 
  slope. 
  The 
  ore 
  breast 
  is 
  said 
  to 
  have 
  averaged 
  8 
  feet. 
  A 
  

   third 
  opening 
  called 
  the 
  Baker 
  has 
  been 
  made 
  on 
  a 
  deposit 
  west 
  of 
  

   the 
  Potter 
  mine. 
  It 
  has 
  produced 
  only 
  a 
  few 
  hundred 
  tons. 
  The 
  

   dumps 
  at 
  the 
  Potter 
  mine 
  contain 
  possibly 
  2000 
  tons 
  of 
  waste 
  ore 
  

   that 
  evidently 
  carried 
  too 
  much 
  pyrite 
  to 
  be 
  shipped 
  to 
  the 
  furnace. 
  

   The 
  sulfur 
  has 
  been 
  oxidized 
  to 
  a 
  great 
  extent 
  and 
  washed 
  out 
  by 
  

   long 
  weathering 
  so 
  that 
  the 
  material 
  might 
  now 
  be 
  valuable. 
  This 
  

   ore 
  came 
  from 
  a 
  zone 
  specially 
  rich 
  in 
  pyrite; 
  most 
  of 
  the 
  output 
  

   was 
  sufficiently 
  free 
  from 
  this 
  mineral 
  to 
  be 
  merchantable. 
  Chemi- 
  

   cal 
  analyses 
  indicate 
  a 
  phosphorus 
  content 
  that 
  meets 
  the 
  Bessemer 
  

   requirement. 
  Of 
  the 
  following, 
  which 
  have 
  been 
  communicated 
  

   by 
  Mr 
  S. 
  R. 
  Potter, 
  No. 
  1 
  relates 
  to 
  a 
  sample 
  from 
  the 
  Potter 
  mine 
  

   and 
  No. 
  2 
  to 
  a 
  sample 
  from 
  the 
  Baker 
  opening.

  Mt 
  Hope 
  mine. 
  The 
  ore 
  belt 
  continues 
  in 
  the 
  direction 
  of 
  the 
  

   strike 
  northwest 
  from 
  the 
  Potter 
  mine 
  and 
  after 
  an 
  interval 
  of 
  a 
  

   little 
  more 
  than 
  half 
  a 
  mile 
  outcrops 
  along 
  the 
  ridge 
  known 
  as 
  Mt 
  

   Hope. 
  According 
  to 
  published 
  accounts 
  ore 
  was 
  mined 
  here 
  50 
  

   years 
  ago. 
  The 
  last 
  period 
  of 
  activity 
  was 
  from 
  1879 
  to 
  1881, 
  when 
  

   15,000 
  tons 
  or 
  more 
  were 
  taken 
  out 
  and 
  mostly 
  stacked 
  at 
  the 
  mine.
