  stream 
  beds 
  both 
  on 
  the 
  east 
  and 
  west 
  of 
  the 
  village 
  of 
  Jhiria, 
  there 
  

   are 
  small 
  but 
  unmistakeable 
  outcrops 
  of 
  the 
  bright 
  red 
  mottled 
  clay, 
  

   either 
  of 
  the 
  Bagra 
  or 
  the 
  Denwa 
  group, 
  confusedly 
  associated 
  with 
  

   trap. 
  If 
  this 
  occurrence 
  were 
  to 
  be 
  much, 
  insisted 
  on, 
  as 
  possibly 
  

   an 
  indication 
  of 
  a 
  former 
  extensive 
  deposit 
  of 
  the 
  same 
  kind, 
  it 
  would 
  

   negative 
  the 
  supposition 
  of 
  an 
  elevated 
  mass 
  of 
  metamorphics 
  in 
  im- 
  

   mediate 
  connection 
  with 
  the 
  existing 
  ridges. 
  If, 
  on 
  the 
  other 
  hand, 
  

   this 
  supposition 
  be 
  adopted, 
  the 
  clays 
  at 
  Jhiria 
  would 
  have 
  to 
  be 
  

   regarded 
  as 
  originally 
  local 
  deposits 
  in 
  a 
  sheltered 
  valley. 
  

  

  In 
  the 
  Anjan 
  at 
  Fatehpiir 
  there 
  is 
  a 
  very 
  important 
  section 
  of 
  the 
  

  

  boundary 
  (see 
  fig. 
  2), 
  ten 
  miles 
  to 
  west 
  of 
  the 
  

   Section 
  on 
  the 
  Anjan. 
  

  

  outcrops 
  at 
  Jhiria. 
  About 
  a 
  mile 
  above 
  the 
  town 
  

  

  a 
  nose 
  of 
  metamorphics 
  projects 
  into 
  the 
  river 
  on 
  the 
  right 
  bank. 
  It 
  is 
  

   the 
  termination 
  of 
  the 
  Bagraj 
  and 
  Deori 
  ridge. 
  The 
  Bagra 
  conglomerates 
  

   have 
  a 
  quaquaversal 
  dip 
  from 
  it. 
  The 
  north-north-westerly 
  dip, 
  down 
  

   stream 
  from 
  the 
  ridge, 
  is 
  reversed, 
  forming 
  a 
  flat 
  symmetrical 
  synclinal 
  ; 
  

   and 
  then, 
  just 
  below 
  the 
  town, 
  there 
  is 
  a 
  sharp 
  normal 
  anticlinal, 
  the 
  dip 
  

   rapidly 
  rising 
  to 
  an 
  angle 
  of 
  70°, 
  to 
  north- 
  30°- 
  west, 
  where 
  the 
  section 
  

   ends 
  ; 
  bedded 
  trap 
  rocks 
  appearing 
  a 
  few 
  yards 
  lower 
  down. 
  Correspond- 
  

   ing 
  -sections 
  are 
  seen 
  along 
  the 
  boundary 
  in 
  the 
  small 
  streams 
  to 
  east 
  and 
  

   west 
  of 
  the 
  Anjan, 
  Structurally, 
  this 
  normal 
  anticlinal 
  with 
  its 
  axis- 
  

   plane 
  dipping 
  southwards 
  is 
  a 
  repetition 
  of 
  the 
  Sitariva 
  section 
  ; 
  and 
  it 
  

   may 
  be 
  taken 
  as 
  a 
  type 
  of 
  the 
  northern 
  boundary 
  of 
  the 
  Satpura 
  basin, 
  

   when 
  these 
  stratified 
  rocks 
  come 
  clearly 
  to 
  the 
  front. 
  

  

  The 
  question 
  again 
  arises, 
  what 
  does 
  this 
  structure 
  indicate, 
  and 
  

  

  what 
  rocks 
  may 
  we 
  infer 
  from 
  it 
  to 
  exist 
  in 
  the 
  

   What 
  it 
  may 
  signify. 
  

  

  concealed 
  ground 
  to 
  the 
  north, 
  beneath 
  the 
  trap 
  

  

  and 
  the 
  alluvium 
  ? 
  In 
  discussing 
  the 
  Sitariva 
  section 
  it 
  was 
  said 
  that 
  

   the 
  flexure, 
  as 
  such, 
  only 
  implied 
  compression; 
  but 
  it 
  may 
  well 
  be 
  

   objected, 
  that 
  a 
  constant 
  form 
  of 
  flexure 
  implies 
  some 
  special 
  deter- 
  

   mining 
  cause 
  besides 
  the 
  presence 
  of 
  a 
  steep 
  face 
  of 
  hard 
  rock 
  bounding
