  in 
  all 
  these 
  cases 
  beds 
  of 
  the 
  same 
  horizon 
  as 
  those 
  at 
  the 
  supposed 
  fault 
  

   are 
  found 
  close 
  by, 
  resting 
  upon 
  the 
  older 
  rocks. 
  Further 
  particulars 
  

   upon 
  this 
  feature 
  will 
  be 
  found 
  in 
  a 
  later 
  section. 
  The 
  same 
  conclusion 
  

   is 
  broadly 
  suggested 
  by 
  the 
  distribution 
  of 
  the 
  strata 
  within 
  the 
  basin. 
  

   The 
  many 
  distinguishable- 
  bands 
  of 
  strata 
  seen 
  in 
  the 
  central 
  section 
  of 
  

   the 
  basin, 
  and 
  amounting 
  to 
  a 
  great 
  thickness, 
  are 
  found 
  to 
  thin 
  out, 
  

   or 
  to 
  die 
  out, 
  both 
  in 
  the 
  strike 
  and 
  the 
  dip. 
  This 
  fact 
  also 
  will 
  be 
  

   exhibited 
  in 
  the 
  following 
  pages. 
  

  

  The 
  so-called 
  Narbada 
  coal-basin 
  does 
  not 
  even 
  appear 
  in 
  the 
  actual 
  

  

  valley 
  of 
  this 
  river, 
  as 
  is 
  approximately 
  the 
  case 
  

   The 
  basin 
  is 
  entirely 
  

   within 
  the 
  Satpura 
  hill- 
  with 
  many 
  of 
  the 
  fields 
  on 
  the 
  Damuda 
  and 
  the 
  

   mass. 
  

  

  Godaveri. 
  The 
  river 
  only 
  touches 
  these 
  forma- 
  

   tions 
  at 
  one 
  spot, 
  where 
  it 
  leaves 
  its 
  deep 
  trench 
  through 
  the 
  trap 
  of 
  the 
  

   Mandla 
  plateau., 
  to 
  enter 
  upon 
  the 
  broad 
  alluvial 
  area 
  which 
  is 
  generally 
  

   understood 
  as 
  the 
  Narbada 
  valley. 
  At 
  that 
  point 
  it 
  crosses 
  obliquely, 
  

   for 
  about 
  five 
  miles, 
  over 
  the 
  outcrop 
  of 
  a 
  narrow 
  band 
  of 
  sandstones 
  

   occurring 
  almost 
  continuously 
  along 
  the 
  fringe 
  of 
  the 
  trappean 
  area, 
  

   and 
  which 
  thus 
  forms 
  a 
  most 
  useful 
  link 
  between 
  the 
  Satpura 
  coal-basin 
  

   and 
  the 
  much 
  larger 
  expanse 
  of 
  the 
  same 
  rocks 
  in 
  South 
  Riwa. 
  The 
  

   alluvial 
  deposits 
  of 
  the 
  Narbada 
  plains 
  seem 
  to 
  be, 
  for 
  the 
  most 
  part, 
  

   underlaid 
  by 
  metamorphic 
  rocks, 
  with 
  which 
  the 
  sandstone 
  series 
  is 
  in 
  

   contact 
  along 
  the 
  south 
  margin 
  of 
  the 
  valley. 
  At 
  many 
  points 
  the 
  

   older 
  rock 
  forms 
  a 
  narrow 
  fringiDg 
  ridge, 
  sometimes 
  reaching 
  to 
  the 
  

   full 
  height 
  of 
  the 
  scarp 
  of 
  sandstone, 
  thus 
  more 
  clearly 
  separating 
  the 
  

   basin 
  of 
  sedimentary 
  rocks 
  from 
  the 
  actual 
  valley 
  of 
  the 
  river. 
  A 
  very 
  

   large 
  portion 
  of 
  the 
  field 
  is 
  drained 
  into 
  the 
  Narbada 
  by 
  the 
  Tawa 
  and 
  

   its 
  tributary 
  the 
  Denwa; 
  the 
  Moran, 
  the 
  Dudhi, 
  and 
  the 
  Sitiiriva 
  

   being 
  the 
  only 
  other 
  streams 
  of 
  importance 
  belonging 
  to 
  the 
  same 
  river- 
  

   basin. 
  In 
  the 
  south-east 
  of 
  the 
  area 
  the 
  Kanhan 
  and 
  the 
  Peneh 
  are 
  

   distantly 
  tributaries 
  of 
  the 
  Godaveri. 
  Thus 
  a 
  main 
  water-shed 
  of 
  the 
  

   peninsula 
  passes 
  obliquely 
  across 
  this 
  corner 
  of 
  the 
  field 
  ; 
  the 
  Motur 
  

   ( 
  1-36 
  )
