  between 
  5° 
  and 
  10°

  but 
  at 
  other 
  places 
  the 
  

   beds 
  roll 
  about 
  a 
  good 
  deal,-*?,

  on 
  the 
  western 
  face 
  of 
  the

   of

  The 
  general 
  dip 
  of 
  the 
  beds 
  of 
  conglomerate 
  and 
  sandstone 
  in 
  the 
  

   northern 
  parts 
  of 
  the 
  Sattavedu 
  hills 
  Mr. 
  King 
  found 
  to 
  be 
  north 
  or 
  

   north-west. 
  To 
  the 
  south 
  of 
  this 
  valley, 
  however, 
  the 
  dip 
  and 
  strike 
  of 
  

   the 
  beds 
  change 
  to 
  the 
  east 
  and 
  south-east. 
  

  

  Eastward 
  of 
  the 
  village 
  of 
  Vembaucum 
  thick 
  beds 
  of 
  coarse 
  conglo- 
  

   merate 
  are 
  exposed 
  along 
  the 
  ridges, 
  and 
  are 
  seen 
  

  

  Vembaucum 
  section. 
  

  

  to 
  dip 
  east 
  at 
  a 
  low 
  angle. 
  

  

  At 
  the 
  southern 
  end 
  of 
  the 
  Sattavedu 
  hills, 
  their 
  structure 
  is 
  more 
  

   plainly 
  seen, 
  their 
  surfaces 
  being 
  here 
  less 
  obscured 
  by 
  debris 
  of 
  weathered 
  

   rock. 
  

  

  In 
  the 
  ridge 
  forming 
  the 
  south-western 
  extremity 
  of 
  the 
  group 
  of 
  

  

  • 
  hills, 
  very 
  coarse 
  and 
  sometimes 
  ferruginous 
  con- 
  

  

  Section 
  at 
  south-west- 
  

   em 
  extremity 
  of 
  the 
  glomerates 
  appear 
  above 
  a 
  considerable 
  talus 
  or 
  

  

  debris. 
  The 
  upper 
  part 
  of 
  the 
  ridge 
  is 
  composed 
  

  

  of 
  similar 
  beds 
  of 
  conglomerate 
  with 
  interbedded 
  irregular 
  layers 
  of 
  

  

  yellow 
  and 
  red 
  sandstone 
  and 
  cherty 
  claystone, 
  all 
  capped 
  by 
  an 
  extremely 
  

  

  coarse 
  conglomerate 
  of 
  rounded 
  or 
  sub-angular 
  fragments 
  of 
  quartzite. 
  

  

  Mr. 
  King 
  could 
  not 
  find 
  any 
  fossils 
  in 
  any 
  of 
  these 
  beds. 
  

  

  The 
  next 
  ridge 
  further 
  east 
  also 
  consists 
  of 
  similar 
  beds. 
  Many 
  of 
  

   the 
  sandstones 
  are 
  pale-yellow 
  cherty 
  claystones, 
  in 
  which 
  Mr. 
  King 
  

   found 
  traces 
  of 
  fragmentary 
  plant 
  remains. 
  These 
  were 
  chiefly 
  frag- 
  

   ments 
  of 
  stems, 
  but 
  no 
  leaves 
  occurred 
  among 
  them. 
  The 
  cementing 
  

   material 
  in 
  several 
  of 
  the 
  conglomerate 
  beds 
  is 
  a 
  similar 
  cherty, 
  clayey 
  

   sandstone. 
  These 
  conglomerates 
  form 
  the 
  greater 
  part 
  of 
  the 
  mass 
  of 
  

   this 
  part 
  of 
  the 
  hills.
