  The 
  portion 
  of 
  the 
  line 
  considered 
  in 
  this 
  paper 
  occupies 
  a 
  distance 
  

   of 
  about 
  40 
  miles, 
  and 
  runs 
  nearly 
  at 
  right 
  angles 
  to 
  the 
  strike 
  of 
  

   all 
  the 
  beds 
  from 
  the 
  Lias 
  to 
  the 
  Coal 
  Measures. 
  

  

  The 
  lower 
  part 
  of 
  the 
  Lias 
  and 
  the 
  Rhsetic 
  beds 
  are 
  entirely 
  

   concealed; 
  but 
  grey 
  marls 
  overlying 
  red 
  marls 
  occur 
  about 
  

   a 
  mile 
  east 
  of 
  Clifton 
  Station, 
  and 
  at 
  the 
  station 
  the 
  Red 
  Marl 
  

   of 
  the 
  Keuper 
  comes 
  on 
  in 
  force. 
  The 
  alluvial 
  deposits 
  of 
  the 
  

   Trent, 
  pierced 
  to 
  a 
  depth 
  of 
  from 
  25 
  to 
  30 
  feet, 
  consist 
  principally 
  

   of 
  loam 
  overlying 
  varying 
  thicknesses 
  of 
  sand 
  and 
  gravel. 
  Horns 
  

   of 
  red 
  deer 
  were 
  found 
  at 
  a 
  depth 
  of 
  25 
  feet. 
  At 
  Dukeries 
  Station 
  

   white 
  flaggy 
  Keuper 
  sandstones 
  appear 
  from 
  beneath 
  the 
  Red 
  

   Marl, 
  and 
  probably 
  represent 
  the 
  eastward 
  extension 
  of 
  the 
  

   Tuxford 
  Stone. 
  A 
  deep 
  well 
  here 
  has 
  been 
  bored 
  to 
  a 
  depth 
  

   of 
  644 
  feet 
  from 
  the 
  present 
  surface, 
  and 
  details 
  of 
  the 
  section 
  

   are 
  given 
  in 
  the 
  paper. 
  South 
  of 
  Kirton 
  there 
  is 
  a 
  deep 
  cutting 
  

   in 
  the 
  Waterstones, 
  and 
  after 
  leaving 
  the 
  escarpment 
  the 
  line 
  

   enters 
  on 
  the 
  great 
  dip-slope 
  of 
  the 
  Bunter 
  Pebble 
  Beds, 
  which 
  

   are 
  shown 
  at 
  Ollerton 
  and 
  at 
  intervals 
  for 
  4 
  miles 
  beyond 
  this. 
  

   There 
  are 
  no 
  sections 
  in 
  the 
  Lower 
  Red 
  and 
  Mottled 
  Sandstones 
  ; 
  

   and 
  west 
  of 
  Warsop 
  the 
  line 
  crosses 
  the 
  dip-slope 
  of 
  the 
  Magnesian 
  

   Limestone. 
  Details 
  of 
  the 
  sections 
  in 
  this 
  rock 
  are 
  given. 
  

  

  Between 
  Scarcliff 
  and 
  Bolsover 
  the 
  line 
  crosses 
  the 
  Permian 
  

   escarpment 
  in 
  a 
  tunnel, 
  the 
  whole 
  of 
  which 
  is 
  in 
  the 
  Coal 
  Mea- 
  

   sures 
  ; 
  these 
  are 
  high 
  up 
  in 
  the 
  series, 
  and 
  contain 
  no 
  coal-seams 
  

   of 
  value. 
  They 
  are 
  not 
  stained 
  red. 
  

  

  West 
  of 
  Arkwright's 
  Town 
  Station 
  is 
  a 
  very 
  complete 
  section 
  of 
  

   beds 
  representing 
  the 
  Middle 
  Coal 
  and 
  Ironstone 
  series 
  (the 
  most 
  

   valuable 
  part 
  of 
  the 
  Derbyshire 
  Coalfield), 
  of 
  which 
  full 
  details 
  are 
  

   given, 
  most 
  of 
  the 
  important 
  coal-seams 
  being 
  readily 
  recognized 
  ; 
  

   and 
  the 
  author 
  describes 
  some 
  remarkable 
  features 
  in 
  the 
  relation- 
  

   ships 
  of 
  some 
  of 
  the 
  sandstones 
  to 
  the 
  other 
  deposits. 
  

  

  The 
  absence 
  of 
  Glacial 
  beds 
  is 
  of 
  much 
  interest 
  ; 
  not 
  a 
  trace 
  of 
  

   genuine 
  Boulder 
  Clay 
  has 
  been 
  seen 
  along 
  the 
  whole 
  line.
