  could 
  not 
  weigh 
  less 
  than 
  4 
  or 
  5 
  tons 
  at 
  the 
  lowest 
  estimate, 
  was 
  quite 
  

   angular, 
  and 
  not 
  very 
  much 
  weathered. 
  

  

  About 
  three 
  quarters 
  of 
  a 
  mile 
  south-east 
  of 
  the 
  above 
  described 
  

   boulder 
  bed, 
  an 
  enormous 
  solitary 
  mass 
  of 
  quartzite 
  protrudes 
  from 
  the 
  

   side 
  of 
  the 
  same 
  hill, 
  but 
  at 
  a 
  greater 
  elevation 
  above 
  the 
  valley. 
  It 
  is 
  

   of 
  the 
  same 
  variety 
  of 
  quartzite, 
  partly 
  dense, 
  partly 
  conglomeratic 
  in 
  

   structure, 
  and, 
  though 
  now 
  broken 
  into 
  several 
  pieces, 
  once 
  evidently 
  

   formed 
  a 
  single 
  block 
  of 
  great 
  size. 
  The 
  cubical 
  dimensions 
  of 
  the 
  

   uncovered 
  part 
  cannot 
  measure 
  less 
  than 
  20 
  or 
  30 
  cubic 
  yards. 
  The 
  

   strike 
  of 
  the 
  bedding 
  shown 
  in 
  this 
  block 
  is 
  north-north-east 
  5° 
  east, 
  

   south-south-west 
  5° 
  west; 
  the 
  dip 
  70° 
  west-north-west 
  5° 
  north. 
  

  

  Crossing 
  hence 
  to 
  the 
  east 
  side 
  of 
  the 
  Naikenpolliam 
  valley, 
  

   another 
  series 
  of 
  enormous 
  blocks 
  occurs 
  on 
  the 
  

  

  Naikenpolliam 
  blocks. 
  

  

  top 
  of 
  a 
  small 
  spur 
  coming 
  close 
  down 
  to 
  the 
  

   east 
  side 
  of 
  the 
  principal 
  stream 
  in 
  the 
  valley 
  and 
  to 
  the 
  head 
  of 
  the 
  tank 
  

   shown 
  in 
  the 
  map, 
  but 
  which 
  now 
  exists 
  no 
  longer. 
  The 
  greater 
  

   number 
  of 
  the 
  blocks 
  here 
  dip 
  to 
  the 
  north, 
  at 
  low 
  but 
  varying 
  angles, 
  

   but 
  some 
  of 
  the 
  largest 
  have 
  been 
  thrown 
  about 
  confusedly 
  in 
  all 
  

   directions. 
  The 
  blocks 
  at 
  this 
  place, 
  even 
  more 
  than 
  elsewhere, 
  ap- 
  

   pear 
  to 
  form 
  the 
  remnants 
  of 
  a 
  continuous 
  bed 
  of 
  quartzite, 
  and 
  I 
  

   fancied 
  I 
  could 
  make 
  out 
  the 
  line 
  of 
  outcrop 
  encircling 
  the 
  point 
  of 
  

   the 
  spur 
  which 
  falls 
  away 
  steeply 
  to 
  the 
  south, 
  the 
  strike 
  of 
  the 
  bedding 
  

   in 
  some 
  large 
  blocks 
  being 
  east 
  and 
  west 
  ; 
  the 
  blocks 
  also 
  are 
  certainly 
  

   less 
  broken 
  up 
  here 
  than 
  near 
  lllatoor, 
  and 
  are 
  generally 
  rather 
  square 
  

   in 
  shape.

  Chinnareadypolliam. 
  stands 
  up 
  in 
  a 
  field 
  just 
  at 
  the 
  foot 
  of 
  the 
  hill 
  

  

  east 
  of 
  Chinnareddypolliam. 
  In 
  shape 
  it 
  is 
  a 
  rude 
  elliptical 
  cone, 
  about 
  

  

  10 
  feet 
  high 
  from 
  the
