  The 
  following 
  analysis 
  quoted 
  from 
  a 
  paper 
  by 
  A. 
  H. 
  Chester

   is 
  of 
  interest, 
  as 
  it 
  represents 
  the 
  average 
  from 
  a 
  large 
  number 
  of 
  

   analyses 
  of 
  Clinton 
  ores 
  from 
  Oneida

  The 
  percentages 
  would 
  indicate 
  that 
  the 
  ores 
  analyzed 
  were 
  chiefly 
  

   from 
  the 
  oolitic 
  bed, 
  though 
  no 
  mention 
  of 
  localities 
  is 
  made 
  in 
  the 
  

   paper. 
  

  

  Phosphorus 
  and 
  sulfur 
  are 
  both 
  comparatively 
  high 
  in 
  the 
  

   Clinton 
  ores. 
  The 
  former 
  is 
  seldom 
  less 
  than 
  .25$ 
  and 
  ranges 
  up 
  to 
  

   more 
  than 
  1$. 
  Reckoned 
  on 
  the 
  basis 
  of 
  metallic 
  iron, 
  the 
  phos- 
  

   phorus 
  content 
  will 
  average 
  from 
  1 
  to 
  2$. 
  The 
  sulfur 
  is 
  more 
  

   variable, 
  being 
  found 
  in 
  some 
  ores 
  only 
  in 
  traces 
  and 
  in 
  others 
  

   running 
  up 
  to 
  .5$. 
  It 
  occurs 
  always 
  in 
  the 
  form 
  of 
  pyrite 
  which 
  

   seems 
  to 
  be 
  associated 
  rather 
  with 
  the 
  shale 
  partings 
  than 
  in- 
  

   termixed 
  with 
  the 
  hematite. 
  Between 
  the 
  ore 
  and 
  wall 
  rock 
  there 
  

   is 
  oftentimes 
  a 
  thin 
  seam 
  of 
  pyrite. 
  

  

  Among 
  the 
  other 
  important 
  impurities 
  of 
  the 
  ores 
  are 
  silica, 
  

   alumina, 
  lime 
  and 
  magnesia. 
  Most 
  of 
  the 
  silica 
  is 
  in 
  the 
  free 
  state 
  

   as 
  quartz. 
  Its 
  proportion 
  varies 
  from 
  a 
  minimum 
  of 
  2 
  or 
  3$ 
  up 
  

   to 
  15$, 
  the 
  higher 
  percentages 
  being 
  shown 
  by 
  oolitic 
  ores. 
  

   In 
  the 
  fossiliferous 
  hematites 
  the 
  average 
  may 
  be 
  placed 
  at 
  about 
  

   7 
  or 
  8$. 
  The 
  alumina 
  is 
  combined 
  with 
  a 
  part 
  of 
  the 
  silica 
  to
