  hills 
  at 
  Cuddapaiy 
  Choultry 
  south-west 
  of 
  Palaveram. 
  The 
  beds 
  forming" 
  

   these 
  two 
  groups 
  seem 
  to 
  be 
  connected 
  by 
  the 
  beds 
  appearing 
  in 
  the 
  

   Nundiveram 
  and 
  Vendalour 
  hills. 
  In 
  some 
  few 
  places 
  the 
  dips 
  disagree 
  

   in 
  direction 
  with 
  the 
  theoretical 
  extensions 
  of 
  continuous 
  foldings, 
  but 
  

   that 
  disagreement, 
  it 
  is 
  not 
  unlikely, 
  may 
  be 
  due 
  to 
  faults, 
  or 
  else 
  to 
  

   slight 
  local 
  reversing 
  of 
  the 
  strata. 
  Such 
  is 
  probably 
  the 
  case 
  with 
  the 
  

   hornblendic 
  and 
  quartzose 
  beds 
  at 
  Ottivakkam 
  (Ottawaucum 
  of 
  map) 
  

   which 
  dip 
  to 
  the 
  west, 
  while 
  the 
  corresponding 
  beds 
  further 
  south 
  and 
  

   north 
  have 
  an 
  undoubted 
  easterly 
  dip. 
  

  

  Hornblendic 
  gneiss 
  of 
  very 
  compact 
  character 
  is 
  well 
  developed 
  on 
  

   St. 
  Thomas' 
  Mount 
  and 
  the 
  Palaveram 
  hills, 
  and 
  the 
  quartzose 
  felspa-

  rocks 
  show 
  at 
  the 
  south 
  end 
  of 
  the 
  Marmalong- 
  bridge 
  and

  the 
  

   south 
  of 
  Paliacuramy. 
  

  

  Of 
  the 
  quartzo-felspathic 
  gneiss 
  the 
  only 
  remarkable 
  development 
  

  

  is 
  that 
  occurring 
  at 
  the 
  Seven 
  Pagodas. 
  At 
  that 
  place 
  called 
  Maha- 
  

  

  valipuram 
  or 
  Mahamalaipuram 
  by 
  the 
  Hindus 
  (the 
  Mahavalipoor 
  of 
  

  

  Southey's 
  " 
  Curse 
  of

  ") 
  is 
  a 
  ridge 
  of 
  the 
  quartzo-felspathic 
  rock 
  

  

  about 
  half 
  a 
  mile 
  in 
  length, 
  running 
  nearly 
  parallel 
  with 
  the 
  beach, 
  and 
  

  

  rising 
  about 
  80 
  feet 
  above 
  the 
  general 
  level 
  of 
  the 
  island. 
  This 
  ridge 
  

  

  has 
  been 
  elaborately 
  sculptured 
  in 
  many 
  places.

  several

  ot 
  considerable 
  beauty 
  have 
  been

  at

  end

  extension 
  of 
  the

  quartzo-felspathic 
  bed 
  

  

  occurs 
  nearly 
  three 
  miles 
  to 
  the 
  north, 
  close 
  to 
  the 
  fishing 
  village 
  of 
  

  

  Padari. 
  Here 
  also 
  are 
  several 
  very 
  interesting 
  temples 
  cut 
  into 
  the 
  rock. 
  

  

  The 
  rock, 
  which 
  is 
  easily 
  quarried, 
  shows 
  its 
  bedded 
  structure 
  very 
  

  

  rarely 
  ; 
  and 
  has 
  hence 
  often 
  been 
  considered 
  a 
  granite.*
