  for 
  or 
  against 
  this, 
  direct 
  evidence 
  is 
  wanting. 
  If 
  then 
  a 
  fault 
  does 
  exist, 
  

   it 
  must 
  be 
  beyond 
  the 
  limits 
  of 
  any 
  observable 
  junction 
  ; 
  and 
  the 
  intro- 
  

   duction 
  of 
  it 
  there 
  would 
  be 
  rather 
  gratuitous, 
  a 
  complication 
  rather 
  

   than 
  a 
  simplification 
  of 
  the 
  observed 
  facts, 
  whether 
  the 
  downthrow 
  be 
  

   assumed 
  to 
  occur 
  on 
  the 
  north 
  or 
  on 
  the 
  south. 
  

  

  The 
  very 
  marked 
  contrast 
  of 
  the 
  structural 
  features 
  to 
  the 
  west 
  

  

  „

  , 
  , 
  and 
  to 
  the 
  east 
  of 
  the 
  Sitariva, 
  along 
  the 
  same 
  

   Change 
  or 
  features 
  to 
  '

  east 
  of 
  the 
  Sitariva. 
  reach 
  of 
  blank 
  boundary, 
  seems 
  puzzling 
  ; 
  but 
  

  

  there 
  are 
  facts 
  to 
  suggest 
  an 
  explanation 
  of 
  this. 
  At 
  about 
  a 
  mile 
  to 
  the 
  

   south 
  of 
  the 
  undisturbed 
  portion 
  of 
  the 
  boundary, 
  there 
  is, 
  south 
  of 
  

   Ranidha, 
  a 
  region 
  of 
  local 
  disturbance 
  to 
  which 
  there 
  is 
  nothing 
  to 
  

   correspond 
  in 
  the 
  same 
  position 
  on 
  the 
  Sitariva. 
  It 
  is 
  thus 
  apparent 
  

   that 
  the 
  compression, 
  which 
  on 
  the 
  west 
  took 
  effect 
  close 
  to 
  the 
  bound- 
  

   ary, 
  operated 
  on 
  the 
  east 
  at 
  some 
  distance 
  from 
  the 
  boundary 
  ; 
  suggest- 
  

   ing 
  simply 
  variations 
  in 
  depth 
  of 
  the 
  sedimentary 
  basin 
  — 
  that 
  the 
  con- 
  

   solidated 
  base-rocks 
  lie 
  at 
  no 
  great 
  depth 
  beneath 
  the 
  undisturbed 
  

   conglomerates 
  to 
  the 
  east 
  of 
  the 
  Sitariva, 
  thus 
  throwing 
  the 
  contortion 
  

   further 
  into 
  the 
  basin, 
  while 
  on 
  the 
  west 
  there 
  must 
  have 
  been 
  (as 
  the 
  

   upfold 
  of 
  the 
  bottom 
  groups 
  declares) 
  a 
  considerable 
  depth 
  of 
  sediment- 
  

   aries 
  close 
  to 
  the 
  boundary. 
  

  

  There 
  is, 
  however, 
  one 
  observation 
  to 
  show 
  that 
  the 
  little 
  ridges 
  

  

  of 
  metamorphics 
  were 
  to 
  a 
  great 
  extent 
  detached 
  

   Outcrop 
  at 
  Jhiria, 
  

   north 
  of 
  the 
  ridge 
  of 
  from 
  any 
  mam 
  upland 
  of 
  these 
  rocks 
  that 
  may 
  

   metamorphics. 
  . 
  , 
  .. 
  . 
  . 
  

  

  have 
  existed 
  as 
  a 
  general 
  limit 
  to 
  the 
  main 
  

  

  sedimentary 
  basin. 
  The 
  ridge 
  of 
  limestone 
  and 
  hornstone 
  west 
  of 
  Deori 
  

   attains 
  a 
  considerable 
  elevation. 
  At 
  its 
  middle 
  and 
  highest 
  point, 
  the 
  

   Dudhi 
  passes 
  directly 
  across 
  it 
  through 
  a 
  precipitous 
  gorge. 
  It 
  is 
  one 
  

   of 
  those 
  tell-tale 
  features 
  of 
  river-formation, 
  pointing 
  to 
  a 
  state 
  of 
  the 
  

   surface 
  very 
  different 
  from 
  the 
  actual 
  one. 
  To 
  west 
  of 
  the 
  Dudhi, 
  on 
  

   the 
  south, 
  the 
  conglomerates 
  lap 
  up 
  against 
  the 
  ridge, 
  forming 
  a 
  scarp 
  

   on 
  the 
  north 
  front. 
  But 
  close 
  to 
  the 
  north 
  base 
  of 
  the 
  ridge, 
  in 
  the
