  The

  A. 
  boring 
  made 
  at 
  Milford, 
  in 
  Iroquois 
  county, 
  was 
  carried 
  to 
  the 
  

   bottom 
  of 
  the 
  Coal 
  Measures, 
  reaching 
  the 
  Lower 
  Carboniferous 
  

   limestone 
  at 
  about 
  200 
  feet, 
  and 
  though 
  two 
  coal 
  seams 
  were 
  passed 
  

   through 
  neither 
  of 
  them 
  were 
  thick 
  enough 
  to 
  be 
  of 
  any 
  practical 
  

   value. 
  The 
  following 
  beds 
  were 
  passed 
  through
