  There

  which 
  can 
  be 
  

   referred

  the 
  Lower 
  Keuper 
  (Waterstones) 
  ; 
  the 
  grey 
  and 
  red 
  

   gypseous 
  marls 
  belong 
  to 
  the 
  Upper 
  Keuper, 
  and 
  have 
  at 
  their 
  base 
  

   a 
  thin 
  band 
  of 
  fine 
  breccia 
  which 
  closely 
  resembles 
  a 
  rock 
  found 
  in 
  

   the 
  neighbourhood 
  of 
  Whitwick, 
  where 
  the 
  Keuper 
  rests 
  upon 
  the 
  

   Forest 
  rocks. 
  It 
  is 
  possible 
  that 
  the 
  20 
  feet 
  of 
  purple 
  marls 
  may 
  be 
  

   of 
  Permian 
  age, 
  but 
  it 
  is 
  more 
  probable 
  that 
  they 
  form 
  part 
  of 
  the 
  

   underlying 
  shales 
  which 
  have 
  been 
  stained 
  by 
  percolation 
  from 
  

   above. 
  In 
  the 
  190 
  feet 
  of 
  beds 
  below 
  the 
  purple 
  marl 
  we 
  have 
  un- 
  

   mistakable 
  Coal-measures, 
  containing 
  a 
  thin 
  seam 
  of 
  coal 
  ; 
  and 
  these 
  

   rest 
  upon 
  dark-coloured 
  bluish 
  shales, 
  undoubtedly 
  belonging 
  to 
  the 
  

   Stockingford 
  Series.

  Stockingford 
  Shales

  Elmesthorpe. 
  — 
  Whilst 
  Mr. 
  

   Bosworth 
  was 
  executing 
  the 
  boring 
  mentioned 
  above, 
  his 
  atten- 
  

   tion 
  was 
  directed 
  to 
  certain 
  indications 
  in 
  a 
  railway-cutting 
  near 
  

   Elmesthorpe 
  Station 
  which 
  led 
  him 
  to 
  believe 
  that 
  the 
  dark 
  

   shales 
  which 
  occur 
  below 
  the 
  Coal-measures 
  in 
  the 
  Sapcote 
  boring, 
  

   and 
  which 
  we 
  now 
  know 
  to 
  be 
  Stockingford 
  Shales, 
  cropped 
  out 
  at 
  the 
  

   surface. 
  This 
  observation, 
  if 
  correct, 
  seemed 
  to 
  me 
  of 
  such 
  very 
  

   great 
  importance 
  in 
  determining 
  the 
  position 
  of 
  the 
  older 
  rocks, 
  that 
  

   I 
  took 
  an 
  early 
  opportunity 
  of 
  visiting 
  the 
  place 
  with 
  Mr. 
  Bosworth, 
  

   and 
  of 
  collecting 
  on 
  the 
  spot 
  all 
  the 
  available 
  evidence. 
  The 
  point 
  in 
  

   question 
  is 
  on 
  the 
  Leicester 
  and 
  Birmingham 
  line, 
  1450 
  yards 
  east 
  

   of 
  Elmesthorpe 
  Station, 
  close 
  to 
  the 
  viaduct 
  by 
  Elmesthorpe 
  Gorse. 
  

   It 
  is 
  almost 
  exactly 
  two 
  miles 
  north-east 
  of 
  the 
  Sapcote 
  Freeholt 
  

   bore-hole. 
  

  

  The 
  railway-cutting 
  is 
  in 
  chalky 
  Boulder-clay, 
  which 
  is 
  in 
  part 
  of 
  

   a 
  dark 
  bluish 
  colour, 
  very 
  unlike 
  that 
  of 
  any 
  other 
  Boulder-clay 
  in 
  

   the 
  neighbourhood. 
  There 
  are, 
  at 
  the 
  present 
  time, 
  no 
  indications 
  of 
  

   any 
  outcrop 
  of 
  the 
  shales 
  at 
  the 
  base 
  of 
  the 
  cutting. 
  The 
  matter 
  

   was, 
  however, 
  proved 
  beyond 
  doubt 
  by 
  a 
  trial-boring 
  which 
  Mr. 
  Bos- 
  

   worth 
  put 
  down 
  in 
  an 
  adjoining 
  field 
  on 
  the 
  north 
  side 
  of 
  the 
  rail- 
  

   way. 
  At 
  a 
  depth 
  of 
  24 
  feet, 
  after 
  passing 
  through 
  dark-coloured 
  

   Boulder-clay, 
  the 
  boring-tool 
  struck 
  solid 
  blue 
  shales, 
  specimens 
  of 
  

   which 
  I 
  have 
  seen, 
  and 
  which 
  are 
  undoubtedly 
  identical 
  with 
  the 
  

   Stockingford 
  Shales 
  of 
  the 
  Sapcote 
  boring. 
  

  

  It 
  is 
  put 
  beyond 
  doubt 
  therefore 
  that
