  purity 
  and 
  market 
  value 
  are 
  secured. 
  The 
  finest 
  grades 
  of 
  crystal- 
  

   line 
  graphite 
  from 
  the 
  Adirondacks 
  bring 
  from 
  lo 
  to 
  20 
  cents 
  or 
  

   even 
  more 
  a 
  pound. 
  

  

  The 
  American 
  mine 
  owned 
  by 
  the 
  Joseph 
  Dixon 
  Crucible 
  Co. 
  

   has 
  for 
  a 
  number 
  of 
  years 
  furnished 
  most 
  of 
  the 
  graphite 
  obtained 
  

   in 
  the 
  State. 
  The 
  mine 
  is 
  situated 
  at 
  Graphite 
  near 
  Hague 
  on 
  

   Lake 
  George. 
  The 
  graphite 
  occurs 
  as 
  disseminated 
  scales 
  or 
  

   flakes 
  in 
  a 
  quartzite 
  of 
  the 
  Precambric 
  series. 
  The 
  quartzite 
  is 
  

   quite 
  widely 
  distributed 
  in 
  the 
  eastern 
  Adirondacks, 
  but 
  no 
  other 
  

   locality 
  has 
  been 
  found 
  where 
  it 
  carries 
  so 
  coarse 
  a 
  flake 
  and 
  at 
  

   the 
  same 
  time 
  is 
  so 
  free 
  from 
  other 
  scaly 
  minerals. 
  The 
  Joseph 
  

   Dixon 
  Crucible 
  Co. 
  owns 
  a 
  mine 
  also 
  just 
  north 
  of 
  Hague 
  near 
  

   the 
  lake 
  shore 
  and 
  on 
  Lead 
  hill 
  west 
  of 
  Ticonderoga, 
  but 
  these 
  

   were 
  not 
  operated 
  in 
  1908. 
  The 
  product 
  of 
  the 
  American 
  mine, 
  

   after 
  the 
  first 
  separation 
  at 
  the 
  local 
  mill, 
  is 
  refined 
  at 
  the 
  com- 
  

   pany's 
  mill 
  at 
  Ticonderoga. 
  

  

  The 
  Crown 
  Point 
  Graphite 
  Co. 
  was 
  operative 
  for 
  a 
  short 
  time 
  

   only 
  during 
  the 
  past 
  year, 
  as 
  it 
  was 
  engaged 
  in 
  building 
  a 
  mill 
  

   at 
  the 
  mines 
  near 
  Chilson 
  lake, 
  Essex 
  co. 
  The 
  deposit 
  belongs 
  to 
  

   a 
  different 
  type 
  than 
  that 
  described 
  above, 
  the 
  graphite 
  occurring 
  

   in 
  bunches 
  and 
  scattered 
  flakes 
  within 
  beds 
  of 
  crystalline 
  lime- 
  

   stone. 
  The 
  process 
  of 
  separation 
  devised 
  by 
  the 
  company 
  is 
  said 
  

   to 
  consist 
  in 
  crushing 
  the 
  limestone 
  to 
  a 
  powder 
  and 
  recovering 
  

   the 
  graphite 
  on 
  screens. 
  Where 
  the 
  quartzite 
  is 
  the 
  gangue, 
  the 
  

   graphite 
  is 
  separated 
  by 
  gravity 
  or 
  flotation 
  methods. 
  The 
  Crown 
  

   Point 
  Graphite 
  Co. 
  has 
  a 
  finishing 
  mill 
  at 
  Crown 
  Point 
  Center. 
  

  

  The 
  Glens 
  Falls 
  Graphite 
  Co. 
  made 
  a 
  small 
  production 
  in 
  1908 
  

   from 
  the 
  mines 
  at 
  Couklingville, 
  Saratoga 
  co. 
  The 
  graphite 
  is 
  

   found 
  in 
  a 
  quartz 
  schist, 
  a 
  feldspathic 
  representative 
  of 
  the 
  Pre- 
  

   cambric 
  sediments. 
  

  

  Extensive 
  beds 
  of 
  the 
  graphitic 
  quartzites 
  occur 
  near 
  Rock 
  pond, 
  

   Essex 
  CO., 
  7 
  miles 
  north 
  of 
  the 
  American 
  mine, 
  and 
  have 
  been 
  

   under 
  development 
  by 
  John 
  D. 
  Bly 
  of 
  Crown 
  Point. 
  The 
  work 
  

   done 
  in 
  the 
  past 
  year 
  has 
  shown 
  the 
  existence 
  of 
  a 
  rich 
  seam, 
  which 
  

   assays 
  up 
  to 
  20 
  per 
  cent 
  carbon, 
  and 
  a 
  very 
  large 
  area 
  of 
  lower 
  

   grade 
  rock. 
  

  

  The 
  Saratoga 
  Graphite 
  Co. 
  has 
  been 
  recently 
  organized 
  for 
  the 
  

   purpose 
  of 
  working 
  a 
  deposit 
  near 
  Saratoga 
  Springs.

  The 
  production 
  of

  is 
  made 
  in 
  the 
  central
