  Analysis 
  No. 
  5 
  is 
  of 
  a 
  sample 
  taken 
  across 
  the 
  face 
  of 
  the 
  Sanford 
  

   pit. 
  The 
  ore 
  here 
  is, 
  no 
  doubt, 
  above 
  the 
  average 
  for 
  the 
  whole 
  

   deposit, 
  and 
  the 
  first 
  three 
  analyses 
  perhaps 
  are 
  more 
  representa- 
  

   tive. 
  It 
  will 
  be 
  seen 
  that 
  aside 
  from 
  the 
  Cheney 
  pit 
  all 
  of 
  the 
  ores 
  

   are 
  low 
  in 
  phosphorus 
  and 
  sulfur 
  and 
  well 
  within 
  the 
  requirements 
  

   for 
  Bessemer 
  ores. 
  

  

  MOOSE 
  MOUNTAIN 
  DEPOSITS 
  

  

  Moose 
  mountain 
  is 
  a 
  prominent 
  peak 
  3 
  miles 
  north 
  of 
  Hammond- 
  

   ville, 
  on 
  the 
  edge 
  of 
  the 
  central 
  anorthosite 
  area. 
  The 
  deposits 
  

   occur 
  on 
  the 
  shoulder 
  of 
  the 
  peak, 
  a 
  little 
  east 
  of 
  the 
  summit, 
  at 
  an 
  

   altitude 
  of 
  about 
  2000 
  feet, 
  as 
  nearly 
  as 
  can 
  be 
  determined. 
  They 
  

   were 
  opened 
  several 
  years 
  ago 
  by 
  the 
  Crown 
  Point 
  Iron 
  Co., 
  in 
  an 
  

   experimental 
  way, 
  but 
  only 
  a 
  few 
  hundred 
  tons 
  of 
  ore 
  have 
  been 
  

   taken 
  out. 
  The 
  trail 
  to 
  the 
  mines 
  leads 
  up 
  the 
  eastern 
  side 
  of 
  the 
  

   mountain, 
  following 
  the 
  brook 
  which 
  empties 
  into 
  Paradox 
  creek 
  

   below 
  the 
  outlet 
  of 
  Round 
  pond. 
  At 
  the 
  point 
  where 
  the 
  trail 
  

   branches 
  off, 
  the 
  outcrops 
  are 
  of 
  augite 
  syenite, 
  but 
  this 
  rock 
  

   gives 
  way 
  a 
  few 
  hundred 
  feet 
  west 
  to 
  anorthosite, 
  the 
  contact 
  being 
  

   marked 
  by 
  a 
  garnetiferous 
  zone 
  which 
  seems 
  to 
  be 
  a 
  metamor- 
  

   phosed 
  phase 
  of 
  the 
  syenite. 
  Near 
  the 
  deposits 
  gabbro 
  appears 
  

   and 
  forms 
  the 
  immediate 
  country 
  rock. 
  It 
  is 
  doubtless 
  a 
  large 
  

   intrusion 
  in 
  the 
  anorthosite. 
  It 
  has 
  a 
  strongly 
  gneissoid 
  texture 
  

   with 
  much 
  red 
  garnet 
  that 
  has 
  evidently 
  formed 
  at 
  the 
  expense 
  of 
  

   the 
  feldspar, 
  and 
  hornblende 
  as 
  the 
  main 
  dark 
  constituent. 
  

  

  The 
  ore 
  bodies 
  consist 
  of 
  bands 
  or 
  lenticular 
  masses 
  striking 
  

   about 
  northwest 
  and 
  apparently 
  dipping 
  northeast. 
  The 
  main 
  

   pit 
  is 
  perhaps 
  40 
  feet 
  long 
  and 
  from 
  4 
  to 
  5 
  feet 
  wide. 
  The 
  ore 
  in 
  its 
  

   prevailing 
  character 
  is 
  but 
  an 
  enriched 
  portion 
  of 
  the 
  gabbro 
  

   averaging 
  not 
  more 
  than 
  40 
  per 
  cent 
  in 
  iron. 
  The 
  magnetite 
  is 
  finely 
  

   divided 
  and 
  is 
  intergrown 
  with 
  pyrite. 
  At 
  one 
  pit 
  specimens 
  were 
  

   collected 
  which 
  showed 
  a 
  more 
  coarsely 
  textured 
  material 
  above 
  

   the 
  average 
  in 
  richness. 
  The 
  deposits 
  appear 
  to 
  be 
  of 
  small 
  extent, 
  

   judging 
  from 
  the 
  limited 
  areas 
  of 
  magnetic 
  attraction 
  surrounding 
  

   them. 
  

  

  SPLIT 
  ROCK 
  MINE 
  

  

  Split 
  Rock 
  mountain, 
  on 
  which 
  the 
  mine 
  of 
  that 
  name 
  is 
  located, 
  

   is 
  an 
  offshoot 
  of 
  the 
  Adirondacks 
  forming 
  the 
  western 
  shore 
  of 
  

   Lake 
  Champlain 
  for 
  some 
  distance 
  between 
  Westport 
  and 
  the 
  

   village 
  of 
  Essex. 
  It 
  rises 
  abruptly 
  from 
  the 
  lake 
  level 
  as 
  a 
  series 
  of
