   No.

  is 
  an 
  average 
  analysis 
  of 
  ore 
  from 
  the 
  Franklin 
  and 
  Clin- 
  

   ton 
  mines 
  made 
  by 
  A. 
  H. 
  Chester 
  in 
  1873. 
  No. 
  5 
  is 
  from 
  a 
  

   sample 
  of 
  ore 
  from 
  the 
  Clinton 
  mine, 
  J. 
  B. 
  Britton, 
  analyst. 
  

   With 
  the 
  exception 
  of 
  no. 
  1 
  which 
  is 
  taken 
  from 
  the 
  report 
  by 
  

   John 
  C. 
  Smock, 
  the 
  analyses 
  are 
  quoted 
  from 
  Putnam's 
  paper 
  

   in 
  the 
  Report 
  of 
  the 
  Tenth 
  Census. 
  

  

  The 
  variations 
  in 
  the 
  iron 
  percentages 
  shown 
  by 
  the 
  analyses 
  

   are 
  extreme 
  and 
  may 
  be 
  ascribed 
  to 
  lack 
  of 
  uniformity 
  in 
  taking 
  

   samples. 
  The 
  ore 
  as 
  roughly 
  mined 
  will 
  run 
  about 
  40^; 
  the 
  

   average 
  return 
  during 
  the 
  last 
  period 
  of 
  operations 
  is 
  stated 
  to 
  

   have 
  been 
  40.27^. 
  By 
  removing 
  the 
  rock 
  parting 
  the 
  content 
  

   can 
  be 
  raised 
  to 
  45$. 
  The 
  median 
  12 
  inches 
  or 
  so 
  of 
  the 
  oolitic 
  

   bed 
  will 
  assay 
  above 
  50^. 
  

  

  The 
  red
