  Analyses 
  1 
  and 
  2 
  are 
  of 
  crude 
  ore 
  from 
  the 
  mines 
  of 
  the 
  Peru 
  

   Steel 
  & 
  Iron 
  Co., 
  at 
  the 
  east 
  end, 
  and 
  No. 
  3 
  of 
  concentrates 
  made 
  

   by 
  the 
  same 
  company. 
  The 
  higher 
  phosphorus 
  found 
  in 
  the 
  con- 
  

   centrates 
  proportionately 
  to 
  that 
  shown 
  in 
  the 
  analyses 
  of 
  the 
  ore 
  

   is 
  abnormal 
  and 
  contrary 
  to 
  the 
  usual 
  experience 
  in 
  the 
  treatment 
  

   of 
  magnetites, 
  at 
  least 
  by 
  magnetic 
  methods. 
  The 
  concentration 
  

   practice 
  at 
  the 
  Palmer 
  hill 
  mines 
  consisted 
  in 
  first 
  roasting 
  the 
  ore 
  

   so 
  as 
  to 
  render 
  it 
  more 
  friable 
  and 
  then 
  crushing 
  by 
  stamps 
  and 
  

   passing 
  the 
  broken 
  ore 
  over 
  jigs. 
  The 
  bloom 
  iron 
  made 
  by 
  the 
  com- 
  

   panies 
  was 
  mostly 
  shipped 
  to 
  Pennsylvania 
  for 
  manufacture 
  into 
  

   crucible 
  steel. 
  

  

  Production. 
  The 
  output 
  of 
  the 
  mines 
  owned 
  by 
  the 
  J. 
  & 
  J. 
  Rogers 
  

   Co. 
  averaged 
  about 
  25,000 
  tons 
  annually 
  for 
  a 
  period 
  of 
  40 
  years. 
  

   The 
  production 
  by 
  the 
  Peru 
  Steel 
  & 
  Iron 
  Co. 
  is 
  not 
  known, 
  nor 
  the 
  

   quantity 
  mined 
  before 
  the 
  organization 
  of 
  the 
  two 
  companies. 
  It 
  is 
  

   safe, 
  however, 
  to 
  estimate 
  the 
  total 
  yield 
  at 
  over 
  1,000,000 
  tons 
  

   crude 
  ore. 
  The 
  average 
  assay 
  in 
  iron 
  may 
  be 
  placed 
  at 
  about 
  40 
  

   per 
  cent. 
  

  

  Other 
  mines 
  in 
  the 
  district 
  

  

  Jackson 
  hill. 
  The 
  mines 
  at 
  this 
  locality 
  are 
  based 
  on 
  two 
  or 
  three 
  

   parallel 
  bodies 
  that 
  outcrop 
  north 
  and 
  south 
  of 
  the 
  road 
  leading 
  

   from 
  Palmer 
  hill. 
  They 
  lie 
  on 
  the 
  western 
  side 
  of 
  the 
  hill 
  at 
  from 
  

   1000 
  to 
  1 
  150 
  feet 
  elevation. 
  Their 
  course 
  is 
  n. 
  20 
  e. 
  and 
  dip 
  high 
  

   to 
  the 
  north. 
  The 
  two 
  main 
  pits 
  are 
  each 
  about 
  500 
  feet 
  long 
  and
