  represent

  (Bundair) 
  - 
  1 
  If 
  such 
  be 
  the 
  case, 
  the 
  cover- 
  

   ing 
  sandstone 
  must 
  be 
  upper 
  Bhanrer. 
  

  

  It 
  would 
  thus 
  appear 
  that 
  the 
  several 
  groups 
  of 
  the 
  upper 
  Vin- 
  

   dhyans 
  are 
  represented 
  in 
  the 
  lower 
  Narbada 
  area. 
  But 
  as 
  this 
  is 
  still 
  

   problematical, 
  they 
  have 
  been 
  represented 
  by 
  one 
  general 
  colour. 
  

  

  The 
  thickness 
  of 
  the 
  Vindhyans 
  in 
  this 
  area 
  has 
  been 
  reckoned 
  

   by 
  Mr. 
  Blanford 
  at 
  some 
  10,000 
  feet. 
  2 
  This 
  estimate 
  is 
  certainly 
  a 
  

   very 
  moderate 
  one. 
  Yet, 
  as 
  rippling 
  is 
  rather 
  common, 
  the 
  deposits 
  

   must 
  have 
  accumulated 
  in 
  shallow 
  water. 
  

  

  The 
  Vindhyans 
  have 
  nowhere 
  yielded 
  any 
  fossils 
  yet 
  ; 
  3 
  and 
  in 
  this 
  

   absence 
  nothing 
  can 
  be 
  said 
  with 
  any 
  certainty 
  either 
  about 
  the 
  age 
  or 
  

   the 
  conditions 
  of 
  deposition. 
  The 
  balance 
  of 
  evidence, 
  however, 
  has 
  

   been 
  considered 
  to 
  be 
  in 
  favour 
  of 
  their 
  fresh-water 
  origin/ 
  and 
  as 
  far 
  as 
  

   the 
  lower 
  Narbada 
  area 
  is 
  concerned, 
  this 
  hypothesis 
  is 
  strengthened 
  

   by 
  the 
  total 
  absence 
  of 
  limestones, 
  and 
  the 
  prevalence 
  of 
  thin 
  bedding.

  Distribution. 
  — 
  Some 
  thick-bedded, 
  rather 
  soft, 
  whitish 
  sandstones 
  are 
  

   exposed 
  by 
  a 
  streamlet 
  at 
  Agarwara, 
  4 
  miles 
  north-west 
  of 
  Barwai. 
  

   They 
  re-appear 
  at 
  Ghatia, 
  4 
  miles 
  to 
  the 
  east, 
  forming 
  a 
  small 
  scarp 
  

   densely 
  covered 
  with 
  an 
  almost 
  impenetrable 
  underwood 
  of 
  shrubby 
  legu- 
  

   minous 
  plants. 
  Further 
  north, 
  near 
  Katkut, 
  fine-grained 
  shaly 
  beds, 
  

   red, 
  pink, 
  or 
  mottled 
  with 
  irregular 
  ferruginous 
  or 
  carbonaceous 
  concre- 
  

   tions, 
  averaging 
  about 
  8 
  feet 
  in 
  thickness, 
  are 
  exposed 
  by 
  the 
  streams 
  

   and 
  water-courses. 
  At 
  one 
  place 
  they 
  were 
  seen 
  to 
  rest 
  upon 
  a 
  massive
