  The 
  workings 
  are 
  situated 
  on 
  the 
  east, 
  south 
  and 
  west 
  sides 
  of 
  a 
  

   north 
  and 
  south 
  spur 
  of 
  Mt 
  Hope. 
  A 
  drift 
  has 
  been 
  excavated 
  

   entirely 
  through 
  the 
  hill 
  on 
  the 
  strike 
  of 
  the 
  ore, 
  showing 
  a 
  thickness 
  

   of 
  10 
  feet 
  at 
  the 
  western 
  entrance. 
  It 
  opens 
  into 
  a 
  chamber 
  200 
  feet 
  

   long, 
  extended 
  down 
  the 
  dip 
  to 
  the 
  water 
  level, 
  and 
  averaging 
  6 
  or 
  

   8 
  feet 
  in 
  hight. 
  In 
  another 
  drift 
  to 
  the 
  north 
  two 
  seams 
  of 
  ore 
  24 
  

   and 
  80 
  inches 
  thick 
  occur. 
  The 
  dip 
  ranges 
  from 
  io° 
  to 
  30 
  . 
  On 
  the 
  

   east 
  side 
  of 
  the 
  hill 
  there 
  are 
  three 
  open 
  cuts 
  which 
  are 
  on 
  the 
  same 
  

   or 
  parallel 
  veins. 
  

  

  The 
  deposit 
  shows 
  a 
  tendency 
  to 
  form 
  shoots 
  and 
  the 
  walls 
  are 
  

   irregularly 
  spaced 
  with 
  evidences 
  in 
  places 
  of 
  slight 
  breaks. 
  The 
  

   reddish 
  granite 
  which 
  has 
  been 
  mentioned 
  as 
  occuring 
  on 
  the 
  foot- 
  

   wall 
  of 
  the 
  Potter 
  and 
  Podunk 
  mines 
  appears 
  in 
  force, 
  sometimes 
  

   in 
  contact 
  with 
  the 
  ore 
  and 
  again 
  giving 
  way 
  to 
  the 
  schists. 
  Bunches 
  

   of 
  black 
  garnet 
  are. 
  found 
  in 
  the 
  latter, 
  possibly 
  as 
  a 
  result 
  of 
  contact 
  

   action. 
  

  

  The 
  ore 
  averages 
  leaner 
  than 
  the 
  product 
  from 
  the 
  Potter 
  and 
  

   Podunk 
  mines 
  on 
  the 
  eastern 
  end 
  of 
  the 
  belt. 
  It 
  is 
  mixed 
  with 
  peg- 
  

   matite, 
  hornblende, 
  mica 
  and 
  other 
  minerals, 
  but 
  contains 
  little 
  

   pyrite. 
  Most 
  of 
  the 
  material 
  in 
  the 
  stock 
  pile 
  is 
  low 
  grade 
  and 
  

   probably 
  would 
  not 
  assay 
  over 
  30 
  per 
  cent 
  iron 
  as 
  an 
  average. 
  

   The 
  following 
  analyses 
  give 
  the 
  composition 
  of 
  the 
  ore. 
  In 
  No. 
  1 
  

   which 
  has 
  been 
  communicated 
  to 
  the 
  writer 
  by 
  Mr 
  S. 
  R. 
  Potter 
  

   the 
  iron 
  is 
  reported 
  wholly 
  as 
  monoxid. 
  The 
  analysis 
  was 
  made 
  

   by 
  Messrs 
  Booth, 
  Garrett 
  & 
  Blair 
  of 
  Philadelphia. 
  No. 
  2 
  is 
  quoted 
  

   from 
  Maynard, 
  the 
  analysts 
  being 
  Maynard 
  and 
  Wendell.
