  This 
  patch 
  may 
  be 
  looked 
  upon 
  as 
  the 
  continuation 
  of 
  the 
  western 
  

   half 
  of 
  the 
  Kudyerd 
  Basin, 
  the 
  other 
  half 
  having 
  been 
  cut 
  out 
  by 
  the 
  

   Anticlinal 
  Fault, 
  which 
  here 
  runs 
  lengthways 
  along 
  the 
  middle 
  of 
  that 
  

   synclinal. 
  

  

  The 
  structure 
  of 
  the 
  country 
  becomes 
  now 
  for 
  a 
  while 
  somewhat 
  

   obscure 
  ; 
  but 
  a 
  line 
  of 
  fault 
  ranging 
  south 
  from 
  the 
  west 
  side 
  of 
  Ker- 
  

   ridge 
  would 
  seem 
  to 
  run 
  somewhere 
  hereabouts. 
  

  

  Between 
  this 
  and 
  the 
  red-rock-fault 
  is 
  a 
  group 
  of 
  rounded 
  hills, 
  

   known 
  as 
  Bosley 
  Minn, 
  rising 
  to 
  1000 
  or 
  1200 
  feet 
  above 
  the 
  sea. 
  

   They 
  are 
  formed 
  of 
  the 
  Yoredale 
  Quartzites, 
  bent 
  into 
  several 
  very 
  

   sharp 
  folds, 
  and, 
  it 
  may 
  be, 
  broken 
  up 
  by 
  faults. 
  The 
  beds 
  seem, 
  upon 
  

   . 
  the 
  whole, 
  to 
  have 
  been 
  thrown 
  into 
  a 
  number 
  of 
  dome-shaped 
  ele- 
  

   vations 
  ; 
  but 
  it 
  is 
  all 
  but 
  hopeless 
  to 
  try 
  fully 
  to 
  unravel 
  the 
  intricacies 
  

   of 
  this 
  very 
  disturbed 
  district. 
  

  

  Petrological 
  details. 
  — 
  On 
  the 
  east 
  of 
  the 
  district 
  the 
  Yoredale 
  Grit 
  

   is 
  a 
  thick 
  mass 
  of 
  fine, 
  unevenly 
  bedded 
  flagstone, 
  but 
  without 
  the 
  

   massive 
  form 
  which 
  it 
  bore 
  further 
  to 
  the 
  north. 
  

  

  The 
  Kinder 
  Scout 
  Grit 
  is 
  represented 
  by 
  the 
  beds 
  which 
  we 
  have 
  

   spoken 
  of 
  as 
  the 
  Fourth 
  and 
  Fifth 
  Grits 
  ; 
  the 
  latter 
  is 
  a 
  fine-grained 
  

   sandstone, 
  thick-bedded 
  and 
  concretionary 
  at 
  Nithen 
  End, 
  near 
  

   Buxton, 
  and 
  rather 
  more 
  flaggy 
  on 
  the 
  flanks 
  of 
  Axe 
  Edge 
  : 
  the 
  

   fourth 
  bed, 
  which 
  forms 
  the 
  top 
  of 
  that 
  ridge, 
  is 
  a 
  red, 
  crumbly 
  grit, 
  

   not 
  very 
  coarse. 
  This 
  part 
  of 
  the 
  series 
  shows, 
  then, 
  as 
  has 
  been 
  al- 
  

   ready 
  stated, 
  a 
  marked 
  falling 
  off. 
  The 
  other 
  grits, 
  except 
  that 
  they 
  

   are 
  somewhat 
  thinner, 
  have 
  not 
  undergone 
  any 
  great 
  change: 
  the 
  

   third 
  is 
  still 
  coarse 
  and 
  massive, 
  and 
  still 
  forms 
  its 
  usual 
  fine 
  escarp- 
  

   ments. 
  

  

  The 
  thickness 
  of 
  the 
  Millstone 
  Grit 
  in 
  this 
  neighbourhood 
  is 
  about

  A 
  little 
  coal, 
  which 
  is 
  not 
  seen 
  elsewhere, 
  with 
  a 
  hard, 
  Gan- 
  

   nister-like 
  floor, 
  lies 
  hereabouts 
  on 
  the 
  top 
  of 
  the 
  Second 
  Grit. 
  The 
  

   coal 
  lying 
  on 
  the 
  top 
  of 
  the 
  Third 
  Grit 
  has 
  been 
  worked 
  on 
  the 
  west 
  

   side 
  of 
  the 
  trough, 
  at 
  Dane 
  Thorn 
  Colliery, 
  where 
  it 
  was 
  about 
  2 
  feet 
  

   thick, 
  and 
  is 
  now 
  being 
  worked 
  on 
  the 
  east 
  side 
  at 
  Thatch 
  Marsh 
  Col- 
  

  

  * 
  The 
  thickness 
  of 
  the 
  beds 
  above 
  the 
  fourth 
  grit 
  was 
  proved 
  in 
  a 
  tunnel 
  

   driven 
  through 
  them 
  near 
  Buxton, 
  for 
  a 
  section 
  of 
  which 
  I 
  am 
  indebted 
  to 
  Mr. 
  

   Willmot 
  : 
  the 
  thickness 
  of 
  the 
  fourth 
  and 
  fifth 
  grits, 
  and 
  of 
  the 
  shales 
  between, 
  is 
  

   estimated.
