  occur 
  to 
  the 
  east 
  ; 
  there 
  is 
  a 
  very 
  marked 
  change 
  in 
  strike 
  of 
  the 
  Pach- 
  

   mari 
  sandstone 
  as 
  it 
  approaches 
  the 
  Sitariva 
  hills 
  ; 
  the 
  dip 
  becomes 
  

   easterly, 
  and 
  there 
  is 
  a 
  considerable 
  intercalation 
  of 
  clay 
  beds. 
  

  

  The 
  most 
  pressing" 
  question 
  regarding 
  the 
  former, 
  and 
  possibly 
  

   actual., 
  extension 
  of 
  these 
  deposits 
  refers 
  to 
  • 
  the 
  

  

  Possible 
  outliers, 
  with 
  

  

  coal, 
  in 
  the 
  Narbada 
  northern 
  boundary. 
  At 
  many 
  places, 
  the 
  whole 
  

  

  series 
  is 
  unquestionably 
  stopped 
  out 
  against 
  ridges 
  

   of 
  metam 
  onirics 
  ; 
  but 
  elsewhere, 
  for 
  considerable 
  lengths, 
  the 
  deposits 
  

   present 
  steep 
  faces 
  to 
  the 
  plains, 
  no 
  rocks 
  being 
  seen 
  in 
  front 
  of 
  them 
  

   under 
  the 
  alluvium, 
  or 
  over 
  a 
  very 
  large 
  area 
  of 
  the 
  Narbada 
  valley. 
  

   At 
  least 
  in 
  one 
  case 
  there 
  is 
  an 
  outlying 
  outcrop 
  of 
  the 
  sedimentaries 
  

   at 
  the 
  north 
  base 
  of 
  the 
  ridges 
  of 
  metamorphics. 
  The 
  prima 
  facie 
  con- 
  

   clusion 
  certainly 
  is, 
  that 
  at 
  one 
  time 
  the 
  strata 
  extended 
  indefinitely 
  

   over 
  the 
  area 
  of 
  the 
  plains. 
  The 
  facts 
  opposed 
  to 
  this 
  view 
  are, 
  the 
  

   littoral 
  or 
  torrential 
  character 
  of 
  the 
  deposits 
  even 
  at 
  these 
  blank 
  bounda- 
  

   ries 
  ; 
  and, 
  the 
  special 
  features 
  of 
  disturbance 
  in 
  this 
  position, 
  suggesting 
  

   either 
  faulting, 
  or 
  the 
  former 
  presence 
  of 
  obstructing 
  masses 
  of 
  hard 
  

   rocks. 
  The 
  details 
  of 
  this 
  question 
  were 
  fully 
  discussed 
  in 
  a 
  former 
  

   section 
  (§ 
  10), 
  but 
  no 
  decided 
  conclusion 
  could 
  be 
  drawn. 
  The 
  possibi- 
  

   lity 
  of 
  the 
  Barakar 
  group, 
  with 
  its 
  coal, 
  occurring 
  in 
  any 
  such 
  extension 
  

   would 
  make 
  the 
  matter 
  of 
  sufficient 
  importance 
  to 
  recommend 
  some 
  ex- 
  

   perimental 
  boring. 
  It 
  would 
  probably 
  be 
  very 
  soon 
  ascertained 
  whether 
  

   it 
  were 
  worth 
  while 
  to 
  continue 
  the 
  work 
  to 
  any 
  depth. 
  For 
  such 
  a 
  

   trial, 
  Gadarwara 
  and 
  Bankeri 
  would 
  be 
  good 
  positions. 
  

  

  There 
  is 
  a 
  more 
  important 
  practical 
  question 
  connected 
  with 
  the 
  

   Probable 
  greater 
  de- 
  distribution 
  of 
  the 
  groups 
  within 
  the 
  basin, 
  as 
  to 
  

   2SS? 
  witht 
  The 
  Aether 
  the 
  Barakar 
  coal-measures 
  occur 
  exten- 
  

   basin 
  " 
  sively 
  throughout 
  the 
  field, 
  and 
  at 
  what 
  depth 
  

  

  they 
  may 
  be 
  expected 
  to 
  lie. 
  The 
  prospect 
  is 
  based 
  upon 
  the 
  fact 
  of 
  the 
  

   appearance 
  of 
  the 
  two 
  lowest 
  groups 
  at 
  the 
  northern 
  boundary 
  — 
  the 
  

   Barakars 
  at 
  the 
  Sitariva 
  only, 
  and 
  the 
  Talchirs 
  at 
  many 
  places 
  —
