  the 
  eastern 
  vein, 
  which 
  seems 
  to 
  be 
  the 
  principal 
  one, 
  two 
  pits 
  have 
  

   been 
  sunk, 
  330 
  feet 
  apart, 
  to 
  a 
  depth 
  of 
  about 
  30 
  feet. 
  The 
  indi- 
  

   cated 
  width 
  is 
  from 
  8 
  to 
  12 
  feet. 
  The 
  hornblende 
  schist 
  forming 
  

   the 
  walls 
  is 
  streaked 
  by 
  limestone 
  in 
  which 
  phlogopite, 
  titanite 
  

   and 
  coccolite 
  are 
  abundantly 
  distributed 
  in 
  small 
  crystals. 
  Horn- 
  

   blende 
  and 
  pyrite 
  are 
  mixed 
  with 
  the 
  magnetite 
  and 
  much 
  of 
  the 
  

   ore 
  is 
  lean. 
  The 
  two 
  pits 
  on 
  the 
  western 
  vein 
  indicate 
  a 
  width 
  for 
  

   the 
  ore 
  of 
  5 
  feet. 
  According 
  to 
  a 
  report 
  rendered 
  by 
  Mr 
  George 
  D. 
  

   Grannis, 
  who 
  superintended 
  the 
  exploratory 
  operations, 
  the 
  

   deposits 
  have 
  been 
  prospected 
  to 
  some 
  extent 
  by 
  diamond 
  drilling. 
  

   One 
  hole 
  was 
  put 
  down 
  on 
  the 
  north 
  pit 
  of 
  the 
  eastern 
  vein 
  to 
  a 
  

   depth 
  of 
  85 
  feet, 
  all 
  in 
  ore. 
  A 
  second 
  boring 
  was 
  started 
  100 
  feet 
  

   west 
  of 
  the 
  pit 
  for 
  the 
  purpose 
  of 
  intersecting 
  the 
  body 
  at 
  an 
  angle 
  

   and 
  encountered 
  two 
  veins, 
  one 
  4 
  feet 
  and 
  the 
  other 
  10 
  feet 
  wide 
  

   separated 
  by 
  4 
  feet 
  of 
  rock. 
  These 
  may 
  represent 
  the 
  western 
  

   vein 
  above 
  mentioned, 
  here 
  split 
  by 
  a 
  horse 
  of 
  the 
  wall 
  rock. 
  

   Another 
  hole 
  in 
  line 
  with 
  the 
  second 
  but 
  farther 
  south 
  showed 
  

   the 
  two 
  veins 
  to 
  have 
  a 
  thickness 
  of 
  4 
  feet 
  and 
  6 
  feet 
  respectively 
  

   with 
  6 
  feet 
  of 
  rock 
  between 
  them. 
  The 
  following 
  analyses 
  have 
  

   been 
  copied 
  from 
  a 
  report 
  on 
  the 
  property 
  made 
  by 
  Mr 
  Spencer 
  

   B. 
  Newberry.

  Clifton 
  Mines. 
  The 
  Clifton 
  deposits 
  are 
  situated 
  about 
  10 
  miles 
  

   north 
  of 
  Benson 
  Mines, 
  in 
  an 
  unsettled 
  forested 
  district 
  that 
  is 
  

   somewhat 
  difficult 
  of 
  access. 
  They 
  were 
  opened 
  over 
  50 
  years 
  ago 
  

   but 
  have 
  not 
  been 
  worked 
  recently. 
  A 
  charcoal 
  furnace 
  was 
  built 
  

   at 
  Clarksboro 
  by 
  the 
  falls 
  of 
  the 
  Grasse 
  river, 
  3 
  miles 
  distant 
  from 
  

   the 
  mines, 
  and 
  was 
  run 
  for 
  some 
  time 
  on 
  the 
  ore. 
  In 
  1868 
  the 
  

   Clifton 
  Mining 
  Co., 
  which 
  then 
  owned 
  the 
  property, 
  erected 
  a 
  plant 
  

   for 
  manufacturing 
  steel 
  by 
  a 
  direct 
  process, 
  a 
  vent.ure 
  that 
  soon 
  

   proved 
  a 
  failure. 
  The 
  mines 
  were 
  at 
  one 
  time 
  connected 
  with 
  the 
  

   Rome, 
  Watertown 
  & 
  Ogdensburg 
  Railroad 
  near 
  DeKalb 
  Junction 
  

   by 
  a 
  20-mile 
  wooden 
  railway.
