  of

  was

  it

  we 
  have 
  here 
  a 
  more 
  complete 
  representation 
  of 
  

  

  the 
  great 
  c 
  plant-bearing' 
  rock-series 
  of 
  India 
  than 
  in 
  any 
  other 
  part 
  of 
  

  

  the 
  peninsula. 
  It 
  is 
  at 
  least 
  certain, 
  that 
  above 
  the 
  Talchir 
  and 
  the 
  

  

  Barakar 
  groups, 
  there 
  are 
  deposits 
  having 
  features 
  of 
  resemblance 
  to 
  

  

  the 
  upper 
  groups 
  of 
  the 
  Damuda 
  and 
  of 
  the 
  Godaveri 
  fields, 
  and 
  of 
  

  

  thickness 
  equal 
  to, 
  or 
  greater 
  than, 
  that 
  of 
  those 
  strata; 
  while 
  ranging 
  

  

  continuously 
  above 
  those 
  again, 
  we 
  find 
  in 
  the 
  Satpuras 
  many 
  hundred 
  

  

  feet 
  of 
  younger 
  deposits 
  now 
  unrepresented, 
  or 
  but 
  very 
  poorly 
  so, 
  in 
  

  

  those 
  other 
  regions, 
  and 
  hitherto 
  casually 
  noticed 
  as 
  the 
  Mahadevas 
  

  

  and 
  Jabalpurs. 
  This 
  general 
  fact 
  I 
  hope 
  to 
  make 
  clear; 
  but 
  the 
  full 
  

  

  discrimination 
  and 
  designation 
  of 
  the 
  groups, 
  at 
  least 
  of 
  those 
  beneath 
  

  

  the 
  Pachmari 
  sandstone, 
  must 
  await 
  the 
  completion 
  of 
  the 
  detailed 
  work. 
  

  

  The 
  present 
  notice 
  will 
  be 
  purely 
  stratigraphical 
  ; 
  if 
  this 
  determination 
  

  

  of 
  the 
  physical 
  relations 
  be 
  sound, 
  any 
  fossils

  the

  any 
  geological 
  field. 
  On 
  looking 
  at 
  the 
  published 
  sections 
  of 
  many 
  

   European 
  coal-basins, 
  it 
  is 
  at 
  once 
  apparent 
  that 
  they 
  are, 
  or 
  at 
  least 
  

   that 
  the 
  view 
  given 
  implies 
  them 
  to 
  be, 
  portions 
  of 
  a 
  formation 
  once 
  

   spread 
  continuously 
  far 
  beyond 
  the 
  limits 
  of 
  their 
  present 
  area; 
  the 
  

   actual 
  features 
  and 
  limits 
  being 
  primarily 
  due 
  to 
  great 
  crust-movements, 
  

   whether 
  of 
  flexure, 
  or 
  of 
  faulting, 
  or 
  of 
  both. 
  Where 
  such 
  is 
  the 
  case, 
  

   the 
  several 
  subordinate 
  groups 
  of 
  strata 
  in 
  the 
  basin 
  would 
  be 
  expected 
  

   to 
  maintain 
  some 
  approximate 
  uniformity 
  of 
  thickness 
  and 
  of 
  charac- 
  

   ter 
  ; 
  and 
  the 
  changes 
  they 
  exhibited 
  might 
  show 
  little 
  or 
  no 
  connection 
  

   with 
  the 
  present 
  induced 
  boundaries 
  of 
  the 
  field.
