  in 
  production. 
  They 
  are 
  chiefly 
  bessemer 
  ores, 
  of 
  about 
  50 
  per 
  

   cent 
  iron. 
  The 
  leaner 
  ores 
  have 
  been 
  concentrated 
  at 
  Iron 
  ton 
  on 
  

   the 
  railroad 
  to 
  Crown 
  Point, 
  where 
  there 
  is 
  a 
  water 
  power. 
  The 
  

   principal 
  ore 
  body 
  is 
  the 
  old 
  Pen 
  field 
  bed, 
  which 
  has 
  been 
  

   operated 
  in 
  recent 
  years 
  from 
  the 
  opening 
  known 
  as 
  the 
  West 
  End. 
  

   This 
  has 
  furnished 
  a 
  vast 
  quantity 
  of 
  ore, 
  for 
  while 
  in 
  general 
  much 
  

   thinner 
  it 
  has 
  yielded 
  in 
  places 
  a 
  breast 
  from 
  twenty 
  feet 
  six 
  inches 
  

   to 
  thirty 
  feet 
  across. 
  It 
  strikes 
  about 
  northeast 
  and 
  dips 
  south- 
  

   east. 
  The 
  dip 
  is 
  very 
  irregular, 
  beginning 
  in 
  the 
  west 
  end 
  with 
  

   forty-five 
  degrees 
  it 
  soon 
  flattens 
  to 
  about 
  five 
  degrees 
  and 
  

   then 
  rolls 
  abruptly 
  over 
  to 
  sixty 
  degrees. 
  The 
  bed 
  also 
  drops 
  

   away 
  to 
  right 
  and 
  left, 
  as 
  one 
  descends, 
  having 
  thus 
  a 
  very 
  

   curious 
  roll, 
  or 
  dome- 
  shaped 
  outline. 
  Swells 
  of 
  ore 
  run 
  into 
  the 
  foot, 
  

   and 
  smaller 
  veins 
  offset 
  in 
  the 
  same 
  direction. 
  These 
  small 
  off- 
  

   sets 
  are 
  shot 
  ore 
  and 
  very 
  low 
  in 
  phosphorous. 
  The 
  wall 
  rock 
  is 
  a 
  

   granitic 
  aggregate, 
  as 
  stated 
  above, 
  of 
  quartz, 
  and 
  plagioclase, 
  

   very 
  light 
  colored 
  and 
  with 
  the 
  merest 
  shreds 
  of 
  hornblende 
  and 
  

   a 
  few 
  garnets. 
  There 
  are 
  innumerable 
  other 
  openings 
  

   in 
  the 
  vicinity, 
  some 
  very 
  small, 
  and 
  mere 
  pockets, 
  others, 
  

   as 
  'No. 
  7 
  and 
  the 
  Hammond 
  Hill, 
  mines 
  of 
  good 
  size. 
  

   Faults, 
  and 
  attendant 
  breccias 
  are 
  well 
  developed, 
  and 
  

   the 
  accurate 
  structural 
  geology 
  would 
  require 
  very 
  care- 
  

   ful 
  and 
  detailed 
  work. 
  So 
  far 
  as 
  noted 
  by 
  us 
  the 
  wall 
  rock 
  is 
  

   the 
  same. 
  Additional 
  notes 
  on 
  these 
  mines 
  will 
  be 
  found 
  in 
  

   Smock's 
  Iron 
  Mines 
  in 
  the 
  State 
  of 
  New 
  York.

   State 
  Museum, 
  1889, 
  and 
  in 
  Putnam's 
  report 
  in 
  vol. 
  XY, 
  of 
  the 
  

   Tenth 
  Census, 
  p. 
  116.) 
  One 
  or 
  two 
  other 
  little 
  openings 
  have 
  been 
  

   made 
  south 
  of 
  Hammond 
  ville, 
  and 
  the 
  titaniferous 
  ore 
  of 
  Moose 
  

   mountain 
  has 
  been 
  already 
  cited. 
  

  

  Roe's 
  spar 
  bed, 
  mentioned, 
  earlier, 
  may 
  be 
  again 
  referred 
  to. 
  

   For 
  some 
  years 
  it 
  supplied 
  potteries 
  to 
  the 
  south 
  with 
  large 
  quan- 
  

   tities 
  of 
  feldspar. 
  Its 
  remote 
  situation 
  militates 
  against 
  it, 
  

   necessitating 
  too 
  much 
  car:age, 
  but 
  there 
  is 
  an 
  indefinite 
  amount 
  

   of 
  the 
  mineral. 
  Reference 
  should 
  be 
  made 
  to 
  the 
  old 
  phosphate 
  

   mine, 
  about 
  a 
  mile 
  and 
  a 
  half 
  south 
  of 
  Crown 
  Point 
  village, 
  

   from 
  which 
  Emmons 
  named 
  the 
  mammilated 
  phosphorescent 
  

   variety, 
  eupyrchroite 
  in 
  1838.
