  the 
  schists 
  at 
  the 
  base 
  ; 
  ' 
  and 
  they 
  occur 
  at 
  the 
  lowest 
  points 
  in 
  the 
  main 
  

   rivers, 
  the 
  Narbada, 
  the 
  Sher, 
  and 
  the 
  Sakar 
  ; 
  so 
  that, 
  if 
  the 
  sediment- 
  

   aries 
  occur 
  to 
  the 
  north, 
  it 
  must 
  be 
  as 
  outliers. 
  The 
  local 
  disturbances 
  

   of 
  the 
  deposits 
  in 
  this 
  eastern 
  region 
  are 
  very 
  trifling, 
  and 
  are 
  not 
  

   specially 
  exhibited 
  near 
  the 
  main 
  boundary. 
  The 
  only 
  fact 
  here 
  to 
  sug- 
  

   gest 
  a 
  rapid 
  original 
  stopping 
  out 
  of 
  the 
  sedimentaries 
  near 
  the 
  actual 
  

   boundary 
  is 
  the 
  occurrence 
  of 
  massive 
  coarse 
  conglomerates 
  in 
  the 
  cliffs 
  

   over 
  Bachai, 
  at 
  the 
  most 
  advanced 
  point. 
  Such 
  deposits 
  as 
  these 
  are 
  

   never 
  found 
  unless 
  along 
  the 
  boundary 
  ; 
  and 
  independently 
  they 
  would 
  in- 
  

   dicate 
  shore-deposits 
  on 
  the 
  supposition 
  of 
  a 
  water-basin, 
  or 
  torrential 
  

   accumulations 
  if 
  these 
  rocks 
  are 
  of 
  diluvial 
  origin 
  ; 
  in 
  either 
  case 
  imply- 
  

   ing 
  the 
  immediate 
  proximity 
  of 
  an 
  area 
  of 
  denudation. 
  

  

  If 
  the 
  last 
  argument 
  is 
  to 
  carry 
  much 
  weight 
  — 
  and 
  it 
  is 
  not 
  easy 
  

  

  Blank 
  boundary 
  in 
  the

  See

  Jt 
  can 
  be 
  made 
  % 
  nt 
  of— 
  there 
  is 
  a 
  

   i 
  anva 
  region. 
  strong 
  case 
  for 
  the 
  present 
  boundary 
  being 
  very 
  

  

  approximately 
  at 
  the 
  original 
  limits 
  of 
  the 
  deposits. 
  The 
  longest 
  

   stretch 
  of 
  boundary 
  without 
  any 
  appearance 
  of 
  the 
  metamorphics 
  is 
  for 
  

   sixteen 
  miles 
  between 
  Nibhora, 
  the 
  west 
  end 
  of 
  the 
  Kishanpur 
  ridge, 
  

   and 
  Deori, 
  the 
  east 
  point 
  of 
  the 
  next 
  metamorphic 
  ridge 
  ; 
  yet 
  nowhere 
  

   in 
  the 
  whole 
  field 
  are 
  the 
  conglomerates 
  so 
  coarse 
  and 
  so 
  massive. 
  The 
  

   Sitariva 
  flows 
  from 
  the 
  hills 
  in 
  the 
  centre 
  of 
  this 
  blank 
  boundary. 
  To 
  

   the 
  east 
  of 
  the 
  river 
  the 
  thick 
  banks 
  of 
  conglomerate 
  are 
  undisturbed, 
  

   presenting 
  sheer 
  cliffs 
  to 
  the 
  plains, 
  on 
  a 
  line 
  with 
  the 
  northern 
  base 
  of 
  

   the 
  adjoining 
  metamorphic 
  ridges. 
  

  

  At 
  and 
  west 
  of 
  the 
  Sitariva, 
  these 
  same 
  beds 
  exhibit 
  the 
  most 
  re- 
  

   markable 
  instance 
  of 
  intense 
  local 
  disturbance 
  

  

  Contortion 
  at 
  the 
  

  

  boundary 
  on 
  the 
  Sita- 
  that 
  occurs 
  in 
  the 
  whole 
  field. 
  There 
  is 
  a 
  full 
  

  

  riva. 
  

  

  section 
  of 
  it 
  in 
  the 
  river-bed. 
  It 
  is 
  a 
  '

  anticlinal 
  flexure; 
  the 
  beds 
  on 
  the 
  north 
  of 
  the 
  axis-plane 
  being 
  quite 
  

  

  vertical. 
  The 
  feature 
  is 
  attended 
  with 
  considerable 
  elevation, 
  Barakar 
  

  

  and 
  Talchir 
  beds 
  being 
  well 
  exposed 
  in 
  the 
  centre 
  of 
  the 
  flexure
