  The 
  surface 
  deposits 
  at 
  Pana 
  proved 
  to 
  be 
  about 
  127 
  feet 
  thick, 
  

   and 
  consequently 
  they 
  struck 
  the 
  bed-rock 
  considerably 
  below 
  the 
  

   horizon 
  of 
  coal 
  No. 
  14, 
  which 
  outcrops 
  on 
  the 
  creek 
  two 
  or 
  three 
  

   miles 
  south 
  of 
  the 
  city. 
  No. 
  13 
  could 
  not 
  be 
  identified 
  in 
  the 
  bor- 
  

   ing, 
  and 
  its 
  place 
  would 
  be 
  not 
  far 
  below 
  No. 
  15 
  of 
  the 
  section. 
  

   One 
  interesting 
  feature 
  of 
  the 
  superficial 
  deposits 
  here 
  was 
  the 
  

   presence 
  of 
  two 
  distinct 
  Forest 
  beds, 
  or 
  ancient 
  soils, 
  one 
  three 
  and 
  

   a 
  half 
  and 
  the 
  other 
  two 
  and 
  a 
  half 
  feet 
  thick, 
  and 
  separated 
  by 
  

   57 
  feet 
  of 
  blue 
  clay. 
  One 
  or 
  both 
  of 
  these 
  ancient 
  soils 
  have 
  been 
  

   found 
  over 
  a 
  large 
  portion 
  of 
  the 
  State, 
  and 
  they 
  present 
  a 
  serious 
  

   obstacle 
  to 
  the 
  land 
  ice 
  or 
  glacier 
  theory 
  of 
  the 
  origin 
  of 
  the 
  Drift 
  

   deposits. 
  

  

  Another 
  important 
  boring 
  with 
  the 
  diamond 
  drill 
  has 
  been 
  made 
  

   by 
  the 
  Ellsworth 
  Coal 
  Company, 
  two 
  miles 
  west 
  of 
  Danville. 
  This 
  

   boring 
  shows 
  the 
  general 
  development 
  of 
  all 
  the 
  coals 
  in 
  the 
  lower 
  

   Coal 
  Measures 
  from 
  No. 
  7 
  to 
  the 
  bottom 
  of 
  the 
  series. 
  It 
  com- 
  

   mences 
  just 
  below 
  the 
  Danville 
  coal, 
  which 
  is 
  No. 
  7 
  of 
  the 
  general 
  

   section, 
  and 
  ends 
  in 
  the 
  sandstone 
  at 
  the 
  base 
  of 
  the 
  Coal 
  Measures. 
  

   These 
  lower 
  seams 
  have 
  their 
  outcrop 
  in 
  Indiana, 
  and 
  this 
  is 
  the 
  

   first 
  attempt 
  that 
  has 
  been 
  made 
  on 
  the 
  eastern 
  border 
  of 
  the 
  coal 
  

   region 
  in 
  Illinois 
  to 
  ascertain 
  whether 
  any 
  of 
  the 
  lower 
  seams 
  could
