  A 
  second 
  area 
  showing 
  this 
  peculiar 
  lateritic 
  gravel 
  with 
  imple- 
  

   ments 
  occurs 
  about 
  twenty-five 
  miles 
  north-west 
  of 
  Pamur, 
  near 
  the 
  

   village 
  of 
  Nundanawanum. 
  The 
  laterite 
  sea 
  evidently 
  made 
  a 
  deep 
  bay 
  

   here, 
  and 
  has 
  left 
  considerable 
  traces 
  of 
  its 
  presence 
  in 
  the 
  form 
  of 
  gravels 
  

   and 
  dark-red 
  sandy 
  clays, 
  which 
  extend 
  right 
  up 
  to 
  the 
  foot 
  of 
  the 
  

   Vellaconda 
  mountains. 
  The 
  country 
  here 
  at 
  the 
  headwaters 
  of 
  the 
  

   Palair 
  river 
  is 
  much 
  flatter, 
  and 
  probably 
  less 
  elevated, 
  than 
  that 
  around 
  

   Pamur. 
  I 
  obtained 
  several 
  well-shaped 
  implements 
  from 
  the 
  surface 
  

   of 
  a 
  gravelly 
  clay 
  south 
  of 
  the 
  village 
  of 
  Ramiahpully.-" 
  

  

  " 
  With 
  the 
  lateritic 
  formations 
  now 
  described, 
  it 
  will, 
  I 
  believe, 
  be 
  

   found 
  necessary 
  to 
  include 
  the 
  great 
  talus-like 
  banks 
  of 
  boulder-gravel 
  

   occurring 
  along 
  the 
  base 
  of 
  the 
  Vella 
  Condas 
  and 
  the 
  Naggery 
  

   mountains, 
  which 
  are 
  well 
  seen, 
  in 
  the 
  case 
  of 
  the 
  former, 
  at 
  the 
  east 
  end 
  

   of 
  the 
  Dorenal 
  Pass, 
  and 
  at 
  the 
  town 
  of 
  Udayaghiri. 
  In 
  the 
  case 
  of 
  the 
  

   Naggery 
  mountains 
  there 
  is 
  a 
  splendid 
  gravel-bank 
  along 
  the 
  south 
  flank 
  

   of 
  the 
  Naggery 
  mountain 
  itself. 
  In 
  this 
  latter 
  case 
  I 
  observed 
  the 
  

   quartzite 
  boulder 
  shingle 
  to 
  be 
  extensively 
  stained 
  of 
  dark 
  red-brown 
  

   purple, 
  which 
  indicates 
  that 
  the 
  stone 
  had 
  been 
  weathered 
  in 
  the 
  presence 
  

   of 
  ferruginous 
  matter 
  of 
  extraneous 
  origin, 
  the 
  quantity 
  of 
  iron, 
  in 
  any 
  

   shape, 
  in 
  the 
  quartzite 
  being 
  in 
  general 
  extremely 
  small. 
  This 
  ferru- 
  

   ginous 
  matter 
  I 
  believe 
  to 
  have 
  been 
  the 
  lateritic 
  cement 
  by 
  which 
  

   this 
  shingle 
  was 
  partly 
  cemented 
  into 
  a 
  conglomerate 
  precisely 
  the 
  same 
  

   as 
  that 
  now 
  seen 
  around 
  the 
  flanks 
  of 
  the 
  Alicoor 
  hills. 
  The 
  presence 
  

   of 
  such 
  a 
  ferruginous 
  cement 
  at 
  high 
  levels 
  in 
  places 
  where 
  no 
  ferru- 
  

   ginous 
  matter 
  was 
  derivable 
  from 
  the 
  higher 
  grounds, 
  as 
  in 
  the 
  case 
  

   of 
  the 
  Alicoor 
  hills, 
  near 
  Naikenpolliam, 
  nor 
  from 
  the 
  substance 
  of 
  the 
  

   enclosed 
  materials, 
  may, 
  I 
  think, 
  be 
  explained 
  by 
  supposing 
  that 
  the 
  

   highly 
  agitated 
  waters 
  of 
  the 
  laterite 
  sea 
  carried 
  much 
  ferruginous 
  

   matter 
  in 
  suspension 
  — 
  a 
  supposition 
  which 
  is 
  not 
  in 
  the 
  least 
  degree
