  land 
  beyond 
  question. 
  The 
  negative 
  evidence 
  of 
  the 
  entire 
  absence 
  of 
  

   marine 
  organisms 
  may 
  be 
  less 
  reliable 
  as 
  a 
  rule. 
  In 
  this 
  case, 
  however, 
  

   its 
  value 
  is 
  increased 
  by 
  the 
  fact 
  that 
  the 
  closest 
  search 
  was 
  made 
  for 
  

   fossils, 
  but 
  none 
  beyond 
  such 
  as 
  are 
  indicated 
  above 
  have 
  been 
  obtained. 
  

   It 
  may 
  be 
  confidently 
  asserted, 
  therefore, 
  that 
  the 
  Mahadevas 
  of 
  the 
  

   western 
  (lower 
  Narbada) 
  basin, 
  like 
  those 
  of 
  the 
  eastern, 
  are 
  of 
  fresh- 
  

   water 
  origin. 
  The 
  deposit 
  was 
  probably 
  formed 
  in 
  the 
  delta 
  of 
  a 
  river, 
  

   which 
  from 
  the 
  thinning 
  out 
  of 
  the 
  beds 
  to 
  the 
  north-east 
  must 
  have 
  

   brought 
  sediment 
  from 
  that 
  direction. 
  

  

  Absence 
  of 
  Lower 
  Gondwanas. 
  — 
  Mr. 
  Blanford 
  finds 
  resemblance 
  in 
  

   the 
  fine-grained 
  rock 
  mentioned 
  before 
  as 
  occurring 
  near 
  Katkut 
  to 
  

   the 
  finer 
  sandstones 
  of 
  the 
  Damuda 
  series. 
  1 
  But 
  the 
  resemblance 
  is 
  not 
  

   significant, 
  and 
  fine-grained 
  sandstone 
  is 
  abundant 
  in 
  the 
  Mahadevas, 
  

   such 
  as 
  the 
  Bagra 
  stone, 
  used 
  in 
  the 
  Tawa 
  viaduct. 
  But 
  the 
  stratigraphy 
  

   leaves 
  no 
  room 
  to 
  doubt 
  that 
  the 
  rock 
  is 
  only 
  a 
  local 
  variation 
  of 
  the 
  

   Mahadevas 
  : 
  the 
  basal 
  beds 
  of 
  the 
  series 
  are 
  seen 
  to 
  rest 
  either 
  upon 
  

   the 
  Bijawars 
  or 
  the 
  metamorphics 
  throughout 
  the 
  area, 
  from 
  Grhatia 
  

   to 
  Mansingpura, 
  in 
  the 
  Dhar 
  forest; 
  and 
  the 
  absence 
  of 
  a 
  trace 
  of 
  

   the 
  lower 
  coal-bearing 
  series 
  of 
  the 
  Gondwana 
  sytem 
  is 
  notable. 
  

  

  We 
  thus 
  get 
  a 
  decisive 
  answer, 
  though 
  unfortunately 
  in 
  the 
  negative; 
  

   to 
  the 
  important 
  economical 
  question 
  as 
  to 
  the 
  occurrence 
  of 
  coal 
  near 
  

   Barwai. 
  2 
  What 
  prospect 
  there 
  is 
  of 
  its 
  discovery 
  further 
  west, 
  we 
  shall 
  

   see 
  in 
  the 
  next 
  chapter.

  The 
  answer 
  is 
  quite 
  final 
  for 
  the 
  actual 
  outcrops, 
  hut 
  the 
  fact 
  of 
  a 
  Gondwana 
  hasin 
  

   remains. 
  Mahadeva 
  beds 
  are 
  known 
  to 
  overlap 
  on 
  metamorphics 
  within 
  very 
  short 
  distances 
  

   of 
  the 
  coal-measures.
