  The 
  analyses 
  were 
  made 
  from 
  crude 
  ore, 
  but 
  the 
  quantity 
  of 
  

   sulfur 
  shown 
  is 
  rather 
  low 
  for 
  the 
  run 
  of 
  mine, 
  specially 
  in 
  the 
  

   second 
  sample 
  which 
  also 
  contains 
  very 
  little 
  phosphorus. 
  It 
  is 
  of 
  

   interest 
  in 
  this 
  connection 
  to 
  quote 
  Professor 
  Silliman's 
  analyses 
  

   of 
  the 
  pig 
  iron 
  made 
  from 
  the 
  Clifton 
  ores 
  in 
  the 
  old 
  Clarksboro 
  

   furnace. 
  The 
  ore 
  was 
  fluxed 
  with 
  an 
  impure 
  limestone 
  containing 
  

   a 
  considerable 
  proportion 
  of 
  silica.

  In 
  the 
  same 
  vicinity 
  occur 
  two 
  other 
  deposits 
  that 
  were 
  found 
  

   by 
  the 
  early 
  prospectors 
  and 
  were 
  known 
  as 
  the 
  Tooley 
  Lake 
  and 
  

   Sheridan 
  veins. 
  They 
  outcrop 
  in 
  a 
  swampy 
  tract, 
  7 
  and 
  2$- 
  miles 
  

   distant 
  respectively 
  from 
  the 
  Clifton 
  mines. 
  The 
  localities 
  were 
  

   not 
  visited 
  by 
  the 
  writer. 
  In 
  character 
  the 
  ores 
  are 
  similar 
  to 
  

   those 
  just 
  described, 
  as 
  shown 
  by 
  the 
  following 
  analyses,
