  farther 
  to 
  the 
  west 
  is 
  reported 
  by 
  Smock 
  to 
  have 
  a 
  depth 
  of 
  350 
  

   feet 
  on 
  the 
  incline 
  ; 
  of 
  its 
  two 
  levels 
  the 
  upper 
  is 
  about 
  2 
  5 
  feet 
  long 
  

   and 
  the 
  lower 
  driven 
  at 
  a 
  point 
  60 
  feet 
  from 
  the 
  bottom 
  of 
  the 
  slope 
  

   runs 
  off 
  in 
  a 
  southerly 
  direction 
  for 
  160 
  feet 
  and 
  then 
  north 
  60 
  feet. 
  

   This 
  pit 
  supplied 
  most 
  of 
  the 
  shipping 
  ore.

  an 
  adit 
  has 
  been 
  excavated 
  into 
  the 
  hill 
  on 
  a 
  lead 
  

   which 
  in 
  the 
  interior 
  develops 
  into 
  a 
  lens 
  some 
  60 
  or 
  70 
  feet 
  long 
  

   and 
  20 
  feet 
  wide. 
  The 
  Fuller 
  and 
  Essler 
  pits 
  are 
  located 
  at 
  the 
  

   extreme 
  west, 
  the 
  former 
  being 
  opened 
  on 
  a 
  pod 
  of 
  ore 
  50 
  feet 
  wide, 
  

   dipping 
  45 
  west. 
  

  

  The 
  distribution 
  of 
  the 
  ore 
  in 
  disconnected 
  bodies 
  which 
  pitch 
  

   and 
  strike 
  in 
  all 
  directions 
  has 
  probably 
  resulted 
  from 
  the 
  intrusion 
  

   of 
  the 
  granite. 
  The 
  bodies 
  occupy 
  approximately 
  the 
  same 
  horizon 
  

   and 
  have 
  the 
  aspect 
  of 
  an 
  originally 
  continuous 
  band 
  which 
  has 
  

   been 
  disrupted 
  and 
  faulted. 
  The 
  intrusion 
  has 
  exercised 
  also 
  a 
  

   metamorphic 
  influence 
  upon 
  the 
  deposits 
  shown 
  by 
  the 
  abundance 
  

   of 
  garnet 
  and 
  hornblende 
  that 
  often 
  replace 
  the 
  magnetite 
  almost 
  

   completely. 
  Well 
  developed 
  titanite 
  crystals 
  of 
  unusual 
  size 
  are 
  

   found 
  in 
  the 
  contact 
  zone. 
  

  

  The 
  analysis 
  below 
  taken 
  from 
  Putnam's 
  report, 
  gives 
  the 
  com- 
  

   position 
  of 
  the 
  Jayville 
  ore. 
  It 
  was 
  made 
  from 
  a 
  sample 
  of 
  500 
  

   tons 
  mined 
  in 
  1880 
  and 
  shipped 
  to 
  the 
  furnace 
  at 
  Alpine. 
  It 
  

   represents 
  the 
  selected 
  lump 
  ore, 
  sufficiently 
  high 
  in 
  iron 
  to 
  be 
  used 
  

   without 
  concentration.

  Mines 
  on 
  Vrooman 
  ridge, 
  Fine. 
  This 
  locality 
  is 
  4 
  miles 
  north- 
  

   west 
  of 
  Oswegatchie 
  on 
  the 
  Carthage 
  and 
  Adirondack 
  Railroad, 
  in 
  

   the 
  town 
  of 
  Fine. 
  Vrooman 
  ridge 
  is 
  the 
  first 
  of 
  the 
  elevations 
  

   bordering 
  the 
  Oswegatchie 
  river 
  valley 
  on 
  the 
  south. 
  

  

  From 
  a 
  cursory 
  examination 
  of 
  outcrops 
  it 
  appears 
  that 
  the 
  

   ridge 
  is 
  mainly 
  composed 
  of 
  reddish 
  hornblende 
  gneiss, 
  with 
  one 
  or 
  

   more 
  included 
  bands 
  of 
  dark 
  pyritic 
  schists 
  and 
  limestone 
  which 
  

   are 
  doubtless 
  altered 
  sediments. 
  The 
  ore 
  deposits 
  are 
  associated 
  

   with 
  the 
  latter. 
  They 
  have 
  been 
  explored 
  by 
  shallow 
  pits 
  ; 
  appar- 
  

   ently 
  no 
  active 
  mining 
  has 
  been 
  undertaken. 
  So 
  far 
  as 
  could 
  

   be 
  determined 
  by 
  surface 
  observations, 
  there 
  are 
  two 
  parallel 
  

   veins 
  that 
  strike 
  about 
  north 
  and 
  dip 
  50 
  or 
  so 
  to 
  the 
  west.
