  occurs 
  for 
  about 
  200 
  yards 
  north-east 
  by 
  east, 
  another 
  well 
  will 
  be 
  found 
  

   yielding 
  the 
  annexed 
  section 
  : 
  — 
  

  

  Buff-drab, 
  friable, 
  fine 
  grained 
  grits 
  of 
  granitic 
  debris 
  with 
  a 
  few 
  i 
  

   small 
  quartzite 
  pebbles 
  in 
  laminae. 
  Grits 
  slightly 
  false-bedded 
  J

  Total 
  10 
  feet. 
  

  

  The 
  real 
  dip 
  of 
  these 
  beds 
  is 
  1° 
  — 
  1|° 
  north, 
  and 
  they 
  unquestionably 
  

   overlie 
  the 
  conglomerate 
  bed 
  just 
  described. 
  A 
  few 
  hundred 
  yards 
  fur- 
  

   ther 
  up, 
  another 
  well 
  section 
  shows 
  white, 
  and 
  slightly 
  ferruginous 
  

   sandy 
  shales, 
  resting 
  on 
  friable 
  buff 
  sandstones, 
  both 
  dipping 
  north 
  by 
  

   east 
  at 
  2° 
  — 
  2|°. 
  

  

  Still 
  further 
  up 
  the 
  slope 
  in 
  a 
  northerly 
  direction, 
  and 
  a 
  few 
  feet 
  

   below 
  the 
  watershed, 
  which 
  is 
  capped 
  with 
  lateritic 
  gravel, 
  a 
  small 
  sec- 
  

   tion 
  occurs, 
  in 
  which 
  yellow, 
  slightly 
  sandy, 
  fine 
  shales 
  are 
  seen 
  dipping 
  

   north 
  at 
  a 
  low 
  angle, 
  while 
  a 
  few 
  hundred 
  yards 
  across 
  the 
  watershed, 
  

   very 
  similar 
  white 
  and 
  yellowish 
  shales 
  appear 
  in 
  the 
  bank 
  of 
  the 
  Kul- 
  

   laur 
  (the 
  Alicoor 
  nullah), 
  dipping 
  north 
  likewise 
  at 
  a 
  low 
  angle, 
  and 
  to 
  

   all 
  appearances 
  representing 
  the 
  yellow 
  shales 
  seen 
  south 
  of 
  the 
  water- 
  

   shed. 
  There 
  can 
  be 
  little 
  doubt 
  but 
  that 
  these 
  upper 
  shales 
  form 
  the 
  

   upper 
  part 
  of 
  a 
  continuous 
  and 
  unbroken 
  series 
  overlying 
  the 
  Mota- 
  

   polliam 
  coarse 
  conglomerate. 
  There 
  is 
  equally 
  good 
  reason 
  for 
  believing 
  

   that 
  the 
  white 
  shales 
  in 
  the 
  Kullaur 
  are 
  true 
  representatives 
  of 
  the 
  

   Sripermatoor 
  shales, 
  with 
  which 
  they 
  agree 
  very 
  closely 
  in 
  lithological 
  

   character. 
  These 
  white 
  shales 
  extend 
  east 
  from 
  the 
  Kullaur 
  to 
  the 
  

   valleys 
  of 
  the 
  Attrampakkam, 
  Odapei, 
  and 
  Meyyur 
  (Myoor) 
  nullahs. 
  

   Westward 
  they 
  were 
  traced 
  in 
  the 
  banks 
  of 
  the 
  Kullaur 
  to 
  about 
  a 
  mile 
  

   south-east 
  of 
  Alicoor. 
  

  

  The 
  shales 
  in 
  the 
  four 
  villages 
  first 
  mentioned 
  present 
  few 
  features 
  

   of 
  interest, 
  as 
  they 
  are 
  but 
  poorly 
  fossiliferous. 
  In 
  character 
  they 
  are 
  

   very 
  constant, 
  white 
  or 
  yellowish 
  shales 
  with 
  a 
  few 
  partings 
  of 
  slightly
