  MEDLICOTT: 
  SATPURA 
  COAL-BASIN. 
  

  

  first, 
  for 
  a 
  length 
  of 
  some 
  fourteen 
  miles, 
  the 
  scarp 
  is 
  supported 
  upon 
  

   a 
  high 
  undercliff 
  of 
  the 
  metamorphics 
  ; 
  at 
  one 
  point 
  these 
  reach 
  to 
  the 
  

   full 
  height 
  of 
  the 
  range, 
  the 
  sandstone 
  being 
  weathered 
  hack 
  as 
  a 
  low 
  

   second 
  scarp. 
  

  

  In 
  the 
  gorge 
  of 
  the 
  Sakar 
  and 
  Hard, 
  the 
  basin 
  of 
  which 
  adjoins 
  

   In 
  the 
  Sakar 
  and 
  Hard 
  that 
  of 
  the 
  Sher 
  and 
  Machiriva 
  within 
  the 
  hills, 
  

   there 
  is 
  a 
  section 
  exhibiting 
  the 
  conditions 
  in 
  this 
  

   portion 
  of 
  the 
  boundary. 
  At 
  the 
  mouth 
  of 
  the 
  gorge 
  the 
  schists 
  reach 
  

   to 
  nearly 
  half 
  the 
  height 
  of 
  the 
  hill; 
  and 
  upon 
  them 
  rest 
  some 
  500 
  

   feet 
  of, 
  at 
  base, 
  coarse 
  earthy 
  conglomerates, 
  both 
  sandy 
  and 
  calcareous, 
  

   passing 
  into 
  massive 
  conglomeritic 
  sandstone 
  at 
  top. 
  The 
  plane 
  of 
  

   junction 
  gradually 
  slopes 
  to 
  the 
  south, 
  and 
  cuts 
  the 
  river 
  at 
  about 
  

   two 
  miles 
  from 
  the 
  mouth 
  of 
  the 
  gorge. 
  At 
  this 
  point 
  the 
  bottom- 
  

   rock 
  is 
  still 
  the 
  pinkish 
  earthy 
  calcareous 
  conglomerate, 
  at 
  first 
  coarse 
  

   and 
  massive, 
  but 
  soon 
  becoming 
  finer 
  and 
  flaggy, 
  altogether 
  about 
  50 
  

   feet 
  thick. 
  The 
  low 
  southerly 
  dip 
  then 
  brings 
  in 
  overlying 
  flaggy 
  

   sandstone 
  and 
  coaly 
  shales, 
  associated 
  with 
  some 
  strong 
  false-bedded 
  

   sandstone-; 
  massive 
  beds 
  of 
  the 
  latter 
  rock 
  separate 
  these 
  shales 
  from 
  

   the 
  upper 
  band 
  of 
  shales 
  with 
  their 
  jet-coal 
  seen 
  in 
  the 
  Hard 
  at 
  its 
  

   confluence 
  with 
  the 
  Sakar. 
  This 
  second 
  band 
  is 
  covered 
  by 
  the 
  strong 
  

   sandstones 
  of 
  the 
  same 
  type 
  forming 
  the 
  surrounding 
  hills. 
  For 
  some 
  

   three 
  miles 
  the 
  course 
  of 
  the 
  Hard 
  is 
  first 
  from 
  the 
  north-west 
  with 
  

   the 
  fall 
  of 
  the 
  strata, 
  then 
  from 
  the 
  south-west, 
  all 
  through 
  the 
  

   upper 
  massive 
  sandstones; 
  and 
  above 
  these 
  reaches, 
  its 
  course 
  is 
  a 
  

   tortuous 
  one 
  from 
  the 
  south. 
  Along 
  this 
  part 
  of 
  its 
  bed 
  and 
  up 
  the 
  

   Pitnai, 
  for 
  seven 
  miles 
  in 
  a 
  direct 
  line, 
  the 
  carbonaceous 
  band, 
  but 
  with 
  

   little 
  or 
  no 
  coaly 
  matter, 
  is 
  frequently 
  exposed, 
  most 
  intricately 
  as- 
  

   sociated 
  throughout 
  with 
  intrusive 
  trap, 
  either 
  in 
  parallel 
  sheets 
  or 
  in 
  

   transverse 
  protrusions. 
  This 
  section 
  in 
  the 
  Sakar 
  and 
  the 
  Hard 
  corres- 
  

   ponds 
  very 
  closely 
  with 
  that 
  on 
  the 
  Sher 
  and 
  the 
  Machiriva 
  ; 
  but 
  in 
  

   the 
  Sakar 
  it 
  is 
  clearly 
  seen 
  how 
  the 
  massive, 
  high-level 
  conglomerates 
  

   (

  )
