  and 
  below 
  the 
  spot 
  where 
  the 
  Miliola-bea.iing 
  concrete 
  is 
  seen 
  

   resting 
  directly 
  on 
  the 
  Jurassic 
  rocks. 
  

  

  The 
  second 
  locality 
  is 
  on 
  the 
  south 
  side 
  of 
  the 
  Jhurio 
  Hills, 
  in 
  

   the 
  concrete-filled 
  gorge 
  and 
  beyond. 
  The 
  description 
  of 
  these 
  

   deposits 
  would 
  be 
  practically 
  a 
  repetition 
  of 
  the 
  last 
  — 
  only 
  the 
  

   thicknesses 
  are 
  somewhat 
  greater, 
  and 
  the 
  bed-rock 
  is 
  not 
  reached 
  in 
  

   the 
  stream-bottom, 
  where 
  the 
  boulders 
  are 
  seen 
  in 
  the 
  sides. 
  

  

  The 
  third 
  locality 
  is 
  a 
  more 
  remarkable 
  one, 
  namely, 
  that 
  on 
  the 
  

   north 
  side 
  of 
  the 
  Kala 
  Dongar 
  in 
  Patcham. 
  It 
  was 
  here 
  that 
  the 
  

   boulder-beds 
  were 
  first 
  noticed 
  and 
  called 
  loudly 
  for 
  some 
  explana- 
  

   tion. 
  At 
  this 
  spot 
  there 
  are 
  marked 
  on 
  the 
  map 
  of 
  the 
  Trigono- 
  

   metrical 
  Survey 
  two 
  long 
  projecting 
  elevations 
  running 
  out 
  at 
  right 
  

   angles 
  from 
  the 
  Jurassic 
  escarpment, 
  where 
  it 
  is 
  coated 
  with 
  the

  subrecent 
  concrete. 
  These 
  no 
  doubt 
  were 
  originally 
  one, 
  the 
  end 
  

   having 
  been 
  eroded 
  along 
  the 
  dividing 
  watercourse. 
  Their 
  length 
  

   is 
  -^ 
  mile, 
  the 
  united 
  breadth 
  \ 
  mile, 
  and 
  their 
  elevation 
  (not 
  

   marked 
  on 
  the 
  map) 
  is 
  perhaps 
  100 
  to 
  150 
  feet 
  above 
  the 
  plain. 
  

   They 
  have 
  the 
  general 
  aspect 
  of 
  the 
  tip-heaps 
  of 
  a 
  Cyclopean 
  

   railway-embankment 
  in 
  course 
  of 
  construction. 
  As 
  seen 
  weathered 
  

   on 
  the 
  surface 
  they 
  are 
  covered 
  with 
  large 
  fragments 
  of 
  rock 
  from 
  

   \ 
  cwt. 
  downwards, 
  more 
  or 
  less 
  rounded, 
  but 
  not 
  scratched, 
  and 
  

   all 
  to 
  be 
  apparently 
  matched 
  in 
  the 
  neighbouring 
  Jurassic 
  hills. 
  

   Where 
  a 
  section 
  is 
  seen 
  the 
  matrix 
  is 
  rubbly, 
  more 
  or 
  less 
  tufaceous, 
  

   and 
  tough 
  enough 
  to 
  form 
  a 
  cliff. 
  At 
  the 
  base 
  of 
  the 
  valley 
  

   laterite 
  is 
  found, 
  and 
  the 
  long 
  mounds 
  appear 
  to 
  rest 
  upon 
  it.
