  of 
  the 
  village 
  of 
  Dun 
  . 
  (Doon) 
  : 
  there 
  is 
  a 
  small 
  hill 
  capped 
  by 
  it 
  ; 
  and 
  

   on 
  following 
  the 
  bed 
  to 
  the 
  east- 
  south-east 
  it 
  is 
  seen 
  to 
  pass 
  under 
  a 
  little 
  

   cliff 
  of 
  typical 
  Jabalpur 
  sandstone. 
  

  

  In 
  the 
  valley 
  of 
  the 
  Sher, 
  or 
  rather 
  of 
  the 
  Machiriva, 
  an 
  affluent 
  

  

  IntheSherandMachi. 
  of 
  the 
  Sh& 
  close 
  to 
  the 
  main 
  rock-boundary, 
  

   there 
  is 
  a 
  large 
  area 
  irregularly 
  weathered 
  out, 
  

   partly 
  as 
  inliers, 
  from 
  beneath 
  the 
  trap, 
  and 
  entirely 
  formed 
  of 
  the 
  

   Jabalpur 
  group. 
  The 
  junction 
  in 
  the 
  Sher 
  presents 
  one 
  of 
  the 
  best 
  

   instances 
  of 
  supposed 
  faulting 
  at 
  the 
  main 
  boundary, 
  the 
  evidence 
  

   being 
  that 
  the 
  surface 
  of 
  junction 
  of 
  the 
  gneiss, 
  about 
  20 
  feet 
  

   in 
  height, 
  is 
  vertical 
  or 
  even 
  overhanging. 
  The 
  strata 
  in 
  contact 
  

   are 
  at 
  their 
  normal 
  level, 
  and 
  are, 
  moreover, 
  distinctly 
  boundary- 
  

   deposits, 
  containing 
  several 
  conglomeritic 
  layers 
  with 
  angular 
  blocks 
  

   of 
  quartz 
  from 
  the 
  contiguous 
  rocks; 
  and 
  at 
  two 
  miles 
  to 
  the 
  

   west, 
  where 
  the 
  boundary 
  emerges 
  from 
  beneath 
  the 
  alluvium, 
  

   there 
  is 
  an 
  overlapping 
  contact. 
  At 
  about 
  150 
  yards 
  from 
  the 
  

   boundary 
  in 
  the 
  Sher, 
  the 
  earthy 
  and 
  conglomeritic 
  bottom 
  beds 
  

   (which 
  may 
  possibly 
  be 
  Talchir) 
  are 
  overlaid, 
  with 
  a 
  southerly 
  dip, 
  by 
  

   a 
  strong 
  bed 
  of 
  sandstone 
  of 
  the 
  usual 
  Jabalpur 
  type 
  ; 
  upon 
  which 
  rest 
  

   shaly 
  carbonaceous 
  beds 
  containing 
  some 
  strings 
  of 
  jet-coal. 
  This 
  

   band 
  is 
  separated 
  from 
  a 
  similar 
  carbonaceous 
  and 
  coaly 
  band 
  by 
  several 
  

   thick 
  beds 
  of 
  sandstone. 
  The 
  low 
  southerly 
  dip 
  continuing, 
  this 
  upper 
  

   band 
  passes 
  under 
  a 
  very 
  thick 
  mass 
  of 
  sandstone, 
  which 
  lasts 
  for 
  some 
  

   two 
  miles 
  up 
  the 
  Sher, 
  to 
  Karheia, 
  at 
  the 
  trap 
  boundary. 
  A 
  few 
  score 
  

   yards 
  above 
  where 
  the 
  sandstone 
  ends, 
  there 
  is 
  a 
  small 
  outcrop 
  of 
  Lameta 
  

   beds, 
  weathered 
  out 
  from 
  beneath 
  the 
  trap, 
  at 
  Karheia. 
  

  

  The 
  massive 
  sandstone 
  of 
  the 
  Sher 
  extends 
  for 
  a 
  quarter 
  of 
  a 
  mile 
  

  

  up 
  the 
  Machiriva, 
  being 
  there 
  cut 
  off 
  by 
  a 
  broad 
  

   On 
  the 
  Machiriva.

  protrusion

  trap. 
  At 
  and 
  above 
  the 
  village 
  

  

  of 
  Marpiperia 
  this 
  trap 
  is 
  seen 
  in 
  the 
  banks 
  to 
  pass 
  conformably 
  

  

  under 
  sandstones 
  and 
  shales 
  with 
  carbonaceous 
  and 
  coaly 
  layers.
