  beds 
  which 
  form 
  the 
  latter 
  would 
  be 
  found 
  capping 
  the 
  ridge 
  ; 
  they 
  are 
  

   not 
  seen 
  on 
  the 
  ridge 
  however, 
  and 
  have 
  either 
  been 
  denuded 
  away 
  or 
  

   have 
  changed 
  their 
  character 
  from 
  being 
  exposed 
  to 
  influences 
  which 
  

   prevented 
  the 
  hardening 
  of 
  the 
  matrix 
  of 
  the 
  conglomerate 
  beds. 
  

  

  The 
  gneissic 
  rocks, 
  though 
  not 
  seen 
  in 
  positive 
  contact 
  with 
  the 
  base 
  

   of 
  these 
  sedimentary 
  rocks, 
  approach 
  very 
  closely 
  to 
  it 
  at 
  the 
  southern 
  

   extremity 
  of 
  the 
  ridge 
  close 
  to 
  Woterpolliam. 
  Between 
  the 
  south 
  end 
  of 
  

   the 
  ridge 
  and 
  the 
  Connicoma 
  tank 
  (which 
  stands 
  on 
  the 
  edge 
  of 
  the 
  

   Naggery 
  river 
  alluvium) 
  the 
  whole 
  area 
  is 
  occupied 
  by 
  the 
  highly 
  grani- 
  

   toid 
  gneiss. 
  The 
  gneiss 
  is 
  best 
  seen 
  in 
  a 
  deep 
  gully 
  worn 
  by 
  rain 
  torrents 
  

   on 
  the 
  slope 
  close 
  to 
  Woterpolliam 
  village.

  tne

  ridge 
  and 
  

   Naikenpolliam 
  ridge. 
  the 
  Naggery 
  river, 
  are 
  all 
  at 
  a 
  considerably 
  lower 
  

  

  level 
  with 
  reference 
  to 
  the 
  general 
  elevation 
  of 
  the 
  country 
  than 
  are 
  

  

  those 
  just 
  described. 
  

  

  It 
  will 
  be 
  seen 
  on 
  inspecting 
  the 
  map, 
  that 
  this 
  tract 
  of 
  country 
  is 
  

   divided 
  by 
  three 
  quasi-peninsulas 
  of 
  lateritic 
  formations, 
  with 
  three 
  

   intervening 
  spreads 
  of 
  Rajmahal 
  rocks, 
  which 
  occupy 
  the 
  lower 
  

   grounds, 
  and 
  are 
  chiefly 
  exposed 
  in 
  or 
  close 
  to 
  the 
  beds 
  of 
  the 
  principal 
  

   streams. 
  

  

  The 
  quasi-peninsulas 
  of 
  lateritic 
  formations 
  are 
  really 
  low 
  broad 
  

   backed 
  spurs, 
  branching 
  off 
  from 
  the 
  Naikenpolliam 
  hills 
  and 
  rising 
  

   50 
  feet 
  and 
  upwards 
  above 
  the 
  general 
  levels 
  of 
  the 
  intermediate 
  valleys. 
  

   Sections 
  at 
  Woter- 
  The 
  most 
  westerly 
  of 
  the 
  three 
  vaUeys 
  is 
  that 
  

   P 
  olliam 
  - 
  in 
  which 
  the 
  village 
  of 
  Woterpolliam 
  stands. 
  

  

  The 
  Sripermatoor 
  rocks 
  are 
  but 
  badly 
  seen 
  in 
  this 
  valley 
  owing 
  to 
  

   the 
  immense 
  mass 
  of 
  shingle 
  debris 
  rolled 
  down 
  from 
  the 
  higher 
  lying 
  

   conglomerate 
  beds 
  belonging 
  both 
  to 
  the 
  same 
  series 
  and 
  the 
  lateritic 
  

  

  formations.
