  stream 
  on 
  the 
  east 
  of 
  the 
  village. 
  The 
  upper 
  part 
  of 
  the 
  bed 
  is 
  hard, 
  

   compact, 
  and 
  black 
  in 
  colour 
  ; 
  while 
  that 
  below 
  is 
  of 
  a 
  light 
  rusty 
  colour, 
  

   not 
  so 
  hard 
  and 
  in 
  part 
  a 
  mere 
  gravel 
  ; 
  it 
  is 
  unlaminated, 
  and 
  towards 
  

   the 
  base 
  becomes 
  argillaceous. 
  Above 
  this 
  bed 
  is 
  a 
  compact 
  layer 
  of 
  

   yellow 
  calcareous 
  sandstone, 
  with 
  raised 
  markings 
  on 
  the 
  surface, 
  like 
  

   annelid 
  tracks 
  ; 
  and 
  in 
  another 
  part 
  a 
  laminated 
  ferruginous 
  sandstone 
  

   varying 
  in 
  texture, 
  and 
  not 
  persistent. 
  Indeed, 
  the 
  section 
  exhibits 
  

   much 
  irregularity 
  in 
  the 
  deposition 
  of 
  these 
  rocks, 
  the 
  individual 
  mem- 
  

   bers 
  not 
  being 
  continuous 
  throughout. 
  Some 
  fossil 
  wood 
  occurs 
  sparing- 
  

   ly 
  in 
  the 
  agatiferous 
  bed. 
  

  

  In 
  another 
  place 
  farther 
  up 
  the 
  same 
  stream, 
  the 
  following 
  section 
  

   was 
  observed 
  (descending) 
  : 
  — 
  

  

  1, 
  — 
  Dark 
  earthy 
  and 
  coarse 
  soft 
  sandstone. 
  

  

  2. 
  — 
  Agatiferous 
  gravelly 
  conglomerate, 
  with 
  bands 
  and 
  irregular 
  

   partings 
  of 
  dark 
  ferruginous 
  sandstone. 
  

  

  3. 
  — 
  Light-yellow, 
  and 
  then 
  pale-bluish 
  white 
  clays. 
  

  

  There 
  appears 
  to 
  be 
  a 
  considerable 
  thickness 
  of 
  this 
  clay, 
  but 
  it 
  is 
  

   not 
  well 
  exposed, 
  being 
  overrun 
  by 
  debris, 
  and 
  displaced 
  by 
  rain 
  and 
  

   weather. 
  The 
  clay 
  is 
  used 
  by 
  the 
  villagers 
  for 
  washing 
  purposes. 
  No 
  

   fossils 
  were 
  detected 
  here. 
  

  

  The 
  agatiferous 
  bed 
  is 
  most 
  conspicuous 
  and 
  strong 
  on 
  the 
  hill 
  ridge, 
  

   Hill 
  ridge 
  west 
  of 
  two 
  mi 
  le 
  s 
  west 
  of 
  Hathab 
  (six 
  miles 
  south 
  of 
  Go- 
  

   Hatlm 
  b. 
  gha). 
  It 
  is 
  here 
  a 
  hard 
  ferruginous, 
  red 
  and 
  yel- 
  

  

  low, 
  arenaceous 
  conglomerate, 
  enclosing 
  some 
  large 
  pebbles 
  of 
  quartzite 
  

   and 
  flinty 
  agates. 
  This 
  rock 
  forms 
  the 
  crest 
  of 
  the 
  ridge, 
  and 
  rests 
  upon 
  

   a 
  thick-bedded 
  mottled 
  yellow 
  clay, 
  which 
  passes 
  down 
  into 
  rusty-brown, 
  

   coarse, 
  earthy 
  sandstone, 
  with 
  a 
  few 
  runs 
  of 
  agate 
  gravel. 
  It 
  would 
  

   appear 
  that 
  there 
  is 
  a 
  great 
  overlap 
  here, 
  for 
  the 
  lateritic 
  rocks 
  are 
  seen 
  

   shortly, 
  in 
  the 
  plain 
  below 
  the 
  west 
  flank 
  of 
  the 
  ridge. 
  

  

  The 
  stream 
  passing 
  Bari, 
  Hoidar, 
  Gundi, 
  and 
  Hathab 
  does 
  not 
  afford 
  

   any 
  clue 
  to 
  the 
  succession 
  of 
  the 
  beds 
  ; 
  though 
  it 
  crosses 
  from 
  the 
  trap 
  

   area, 
  through 
  the 
  lateritic 
  zone, 
  and 
  traverses 
  the 
  whole 
  breadth 
  of 
  the 
  

   tertiary 
  area 
  to 
  the 
  coast, 
  and 
  is 
  the 
  largest 
  stream 
  in 
  this 
  pari 
  of 
  the 
  field.
