  areas 
  exposed 
  ; 
  but 
  there 
  is 
  also 
  a 
  comparative 
  absence 
  of 
  disturbance 
  

   along" 
  that 
  same 
  narrow 
  outcrop. 
  I 
  am 
  inclined 
  to 
  take 
  both 
  cir- 
  

   cumstances 
  as 
  an 
  indication 
  of 
  the 
  shallowness 
  of 
  the 
  deposits 
  in 
  this 
  

   intermediate 
  ground; 
  and 
  so, 
  by 
  implication, 
  to 
  suggest 
  that 
  general 
  

   contortion 
  of 
  the 
  strata 
  and 
  a 
  profusion 
  of 
  trap 
  may 
  coincide 
  with 
  

   positions 
  of 
  greatest 
  depth. 
  

  

  The 
  peculiar 
  form 
  of 
  pseudo-interstratification 
  assumed 
  by 
  the 
  trap- 
  

  

  pean 
  intrusions 
  is 
  sometimes 
  puzzling. 
  It 
  seems 
  

   Pseudo-interstratifica- 
  

   tion 
  with 
  the 
  upper 
  to 
  affect 
  shaly 
  bands 
  between 
  massively 
  bedded 
  

  

  group. 
  

  

  rocks, 
  and 
  is 
  most 
  frequent 
  in 
  the 
  upper 
  groups, 
  

   especially 
  in 
  the 
  Jabalpurs. 
  When 
  it 
  occurs 
  in 
  disturbed 
  strata, 
  as 
  in 
  

   the 
  section 
  in 
  Fig-. 
  4, 
  it 
  is 
  intelligible 
  enough 
  j 
  but 
  it 
  is 
  very 
  frequent 
  

   between 
  sub-horizontal 
  strata. 
  Some 
  examples 
  occur 
  in 
  the 
  Bagra 
  beds 
  

   in 
  the 
  hills 
  immediately 
  south-west 
  of 
  Fatehpur 
  ; 
  in 
  the 
  hill 
  east 
  of 
  the 
  

   Dudhi 
  at 
  Kampti 
  ; 
  and 
  in 
  the 
  flanks 
  of 
  the 
  Baragaon 
  hills 
  in 
  the 
  gorge 
  

   of 
  the 
  Sitariva. 
  The 
  most 
  complete 
  examples 
  occur 
  in 
  the 
  Jabalpiir 
  

   beds, 
  on 
  the 
  horizon 
  of 
  the 
  coaly 
  shales. 
  For 
  several 
  miles 
  along 
  the 
  

   bed 
  of 
  the 
  Hard, 
  above 
  and 
  below 
  Monighat, 
  trap 
  weathers 
  out 
  from 
  

   beneath 
  the 
  sandstone 
  within 
  every 
  few 
  score 
  yards, 
  occasionally 
  pro- 
  

   truding 
  into 
  connection 
  with 
  masses 
  covering 
  the 
  flanks 
  of 
  the 
  hills. 
  

   The 
  best 
  single 
  existence 
  is 
  seen 
  on 
  the 
  Machiriva, 
  above 
  the 
  village 
  of 
  

   Marpiperia 
  ; 
  the 
  coaly 
  band 
  forms 
  a 
  flat 
  synclinal, 
  about 
  three-quarters 
  

   of 
  a 
  mile 
  wide, 
  and 
  on 
  both 
  sides 
  the 
  trap, 
  is 
  seen 
  on 
  the 
  river's 
  bank 
  

   for 
  several 
  score 
  yards 
  regularly 
  underlying 
  the 
  sandstone. 
  This 
  

   latter 
  rock 
  is 
  visibly 
  affected 
  at 
  the 
  contact, 
  but 
  not 
  broken 
  or 
  tilted, 
  

   except 
  very 
  locally 
  when 
  the 
  injected 
  rock 
  breaks 
  through 
  to 
  higher 
  or 
  

   lower 
  levels. 
  The 
  thickness 
  of 
  the 
  sheet 
  cannot 
  be 
  measured 
  ; 
  it 
  is 
  at 
  

   least 
  20 
  feet, 
  and 
  it 
  exhibits 
  parallel 
  variations 
  of 
  texture, 
  which 
  

   add 
  much 
  to 
  its 
  false 
  appearance 
  of 
  cotemporaneous 
  interstratification. 
  

   This 
  trap 
  is 
  continuous 
  on 
  both 
  sides 
  with 
  a 
  large 
  spread 
  of 
  superficial 
  

   outflow, 
  and 
  is 
  only 
  separated 
  by 
  a 
  narrow 
  strip 
  of 
  denudation 
  from
