  Section 
  6. 
  — 
  (e). 
  The 
  Bijoei 
  hokizon 
  (damuda). 
  

   It 
  has 
  been 
  already 
  stated 
  that 
  only 
  a 
  very 
  cursory 
  notice 
  can 
  now 
  

   Conjectural 
  indications 
  be 
  g" 
  iven 
  of 
  the 
  infra-Pachmari 
  groups. 
  It 
  is 
  not 
  

   unlikely 
  that 
  several 
  sub-divisions 
  may 
  be 
  made 
  

   in 
  those 
  rocks 
  ; 
  I 
  will 
  here 
  only 
  indicate 
  in 
  a 
  general 
  way 
  the 
  Motiir 
  beds, 
  

   and 
  a 
  considerable 
  thickness 
  of 
  strata 
  occurring 
  between 
  them 
  and 
  the 
  

   Pachmari 
  sandstone 
  on 
  the 
  central 
  section. 
  A 
  short 
  way 
  to 
  the 
  south- 
  

   west 
  of 
  Pachmari, 
  about 
  the 
  high-level 
  villages 
  of 
  Rorighat 
  and 
  Almod, 
  

   there 
  are 
  some 
  beds 
  of 
  sandy 
  micaceous 
  shale, 
  locally 
  carbonaceous 
  and 
  

   with 
  faint 
  plant-impressions, 
  immediately 
  underlying 
  the 
  cliffs 
  of 
  mas- 
  

   sive 
  sandstone. 
  In 
  the 
  deep 
  gorge 
  to 
  the 
  west 
  of 
  Rorighat, 
  there 
  is 
  a 
  

   thick 
  band 
  of 
  highly 
  carbonaceous 
  shale 
  ; 
  and 
  again 
  to 
  the 
  east 
  of 
  Almod, 
  

   in 
  the 
  low 
  ground 
  near 
  Bijori, 
  there 
  is 
  a 
  similar 
  band, 
  possibly 
  the 
  same, 
  

   both 
  being 
  several 
  hundred 
  feet 
  below 
  the 
  Almod 
  beds. 
  

  

  It 
  was 
  in 
  this 
  lower 
  band, 
  at 
  the 
  crossing 
  of 
  a 
  stream 
  on 
  the 
  bul- 
  

   The 
  Archegosaums 
  lock-road 
  to 
  Alm6d, 
  about 
  a 
  mile 
  to 
  south-west 
  of 
  

   band 
  at 
  Bijori. 
  Bijori, 
  that 
  the 
  Archegosaums 
  was 
  found 
  ; 
  in 
  honor 
  

  

  of 
  which 
  I 
  will 
  speak 
  of 
  this 
  as 
  the 
  Bijori 
  horizon. 
  Associated 
  with 
  

   all 
  these 
  carbonaceous 
  beds 
  there 
  are 
  massive 
  sandstones, 
  very 
  similar 
  

   to 
  the 
  Pachmari 
  rock 
  ; 
  the 
  northerly 
  dip 
  being 
  maintained 
  throughout. 
  

   Beds 
  of 
  the 
  same 
  description 
  occupy 
  the 
  ground 
  to 
  the 
  south 
  as 
  far 
  as 
  

   the 
  Bichberi 
  valley. 
  

  

  The 
  longitudinal 
  extension 
  of 
  these 
  beds 
  seems 
  very 
  limited. 
  In 
  

   Its 
  extinction 
  to 
  east 
  a 
  complete 
  cross-section 
  on 
  their 
  strike, 
  in 
  the 
  

   Delakari 
  stream 
  and 
  the 
  Denwa, 
  only 
  seven 
  miles 
  

   to 
  the 
  east 
  of 
  Bijori, 
  there 
  is 
  no 
  specific 
  representative 
  of 
  the 
  carbonaceous 
  

   band; 
  only 
  a 
  succession 
  of 
  thick 
  soft 
  sandstones 
  with 
  a 
  few 
  subordinate 
  

   layers 
  of 
  brown 
  and 
  red 
  clay, 
  with 
  occasional 
  faint 
  carbonaceous 
  markings. 
  

   One 
  of 
  these 
  immediately 
  and 
  conformably 
  underlies 
  the 
  cliff 
  of 
  typical 
  

   Pachmari 
  sandstone 
  at 
  the 
  entrance 
  to 
  the 
  gorge 
  of 
  the 
  Denwa.
