  Harmony 
  mines. 
  The 
  most 
  recent 
  developments 
  at 
  Mineville 
  

   are 
  the 
  two 
  Harmony 
  shafts, 
  A 
  and 
  B, 
  which 
  were 
  sunk 
  5 
  or 
  6 
  

   years 
  ago 
  in 
  order 
  to 
  tap 
  a 
  bed 
  of 
  ore 
  revealed 
  by 
  the 
  dipping 
  

   needle 
  and 
  the 
  drill 
  to 
  the 
  south 
  and 
  somewhat 
  to 
  the 
  west 
  of 
  the 
  

   Joker 
  workings, 
  and 
  at 
  a 
  much 
  higher 
  horizon. 
  The 
  Harmony 
  bed 
  

   strikes 
  northwest 
  and 
  dips 
  southwest 
  at 
  a 
  rather 
  flat 
  angle. 
  It 
  is 
  

   10 
  to 
  20 
  feet 
  thick 
  and 
  is 
  cut 
  by 
  at 
  least 
  3 
  narrow 
  trap 
  dikes 
  with 
  

   a 
  strike 
  a 
  few 
  degrees 
  east 
  of 
  north 
  and 
  a 
  vertical 
  dip. 
  They 
  fork 
  

   somewhat 
  and 
  are 
  not 
  absolutely 
  continuous. 
  The 
  dikes 
  occupy 
  

   small 
  faults 
  of 
  10 
  to 
  50 
  feet 
  displacement 
  and 
  strike, 
  in 
  a 
  direction 
  

   to 
  suggest 
  that 
  they 
  are 
  the 
  same 
  with 
  the 
  two 
  in 
  the 
  Miller 
  pit. 
  

  

  The 
  relations 
  of 
  the 
  Harmony 
  ore 
  to 
  the 
  Joker 
  on 
  the 
  one 
  side 
  

   and 
  the 
  Barton 
  hill 
  group 
  on 
  the 
  other 
  are 
  interesting. 
  Our 
  last 
  

   section 
  of 
  the 
  Joker 
  is 
  500 
  feet 
  above 
  Lake 
  Champlain, 
  while
