  position 
  in 
  the 
  bed 
  of 
  shale, 
  it 
  might 
  any 
  moment 
  thin 
  out 
  and 
  disappear. 
  

   The 
  Nummulitics 
  are 
  here 
  nearly 
  vertical 
  or 
  dipping 
  to 
  the 
  North-east. 
  

   Below 
  the 
  limestone 
  some 
  harsh 
  sandstones 
  come 
  in, 
  having 
  the 
  appear- 
  

   ance 
  of 
  having 
  been 
  subjected 
  at 
  some 
  period 
  to 
  intense 
  pressure. 
  Below 
  

   these 
  harsh 
  sandstones, 
  yellowish 
  shales 
  come 
  in 
  containing 
  carbonaceous 
  

   layers 
  but 
  no 
  fossils. 
  Above 
  the 
  Nummulitic 
  limestone, 
  or 
  the 
  yellow 
  

   clay 
  representing 
  it, 
  blue 
  shales 
  come 
  in 
  vertically, 
  quite 
  devoid 
  of 
  fossils 
  

   as 
  near 
  Phoungaeing, 
  and 
  much 
  crushed 
  and 
  disturbed. 
  I 
  may 
  here 
  

   briefly 
  describe 
  the 
  few 
  ranges 
  which 
  here 
  traverse 
  the 
  Nummulitic 
  area. 
  

  

  Crossing 
  the 
  Pani 
  valley 
  in 
  a 
  Westerly 
  direction 
  from 
  Mibouk, 
  the 
  

   first 
  range 
  of 
  any 
  importance 
  is 
  the 
  one 
  formed 
  by 
  the 
  Nummulitic 
  

   ridge, 
  which, 
  commencing 
  near 
  Gengyai 
  terminates 
  between 
  Thambula 
  

   and 
  Pimaeing. 
  This 
  range 
  is 
  in 
  places 
  of 
  considerable 
  height, 
  but 
  not 
  

   equal 
  in 
  this 
  respect 
  on 
  the 
  whole 
  to 
  the 
  next 
  range 
  to 
  the 
  Westward. 
  

   This 
  second 
  range 
  crosses 
  the 
  frontier 
  West 
  of 
  Gengyai 
  and 
  runs 
  down 
  

   with 
  a 
  somewhat 
  curved 
  outline 
  towards 
  Thambula, 
  near 
  which 
  village 
  

   it 
  approaches 
  the 
  last 
  range, 
  and 
  when 
  that 
  dies 
  out, 
  holds 
  on 
  in 
  its 
  

   place 
  as 
  it 
  were, 
  some 
  eight 
  miles 
  further, 
  to 
  the 
  Mahton 
  stream. 
  

   Behind 
  this 
  to 
  the 
  Westward, 
  is 
  another 
  less 
  regular 
  range, 
  and 
  the 
  

   arrangement' 
  of 
  these 
  ranges 
  slightly 
  en 
  echelon 
  to 
  the 
  Nummulitic 
  

   boundary 
  is 
  a 
  noteworthy 
  feature, 
  as 
  the 
  boundary 
  corresponds 
  with 
  

   the 
  strike 
  of 
  the 
  Nummulitic 
  beds, 
  which 
  strike, 
  in 
  the 
  absence 
  of 
  

   faults, 
  might 
  prima 
  facie 
  be 
  supposed 
  to 
  govern 
  the 
  direction 
  of 
  the 
  

   main 
  ranges. 
  This 
  perhaps 
  to 
  a 
  certain 
  extent 
  it 
  does, 
  but 
  not 
  entirely 
  

   so, 
  otherwise 
  the 
  en 
  echelon 
  arrangement 
  of 
  the 
  hill 
  ranges 
  above 
  

   described 
  would 
  not 
  exist. 
  

  

  Another 
  feature 
  of 
  the 
  Nummulitic 
  area 
  is 
  its 
  greater 
  elevation, 
  

   than 
  the 
  ground 
  to 
  the 
  Eastward 
  occupied 
  by 
  the 
  newer 
  Terti- 
  

   aries, 
  as 
  marked 
  by 
  the 
  sensible 
  descent 
  experienced 
  when 
  crossing 
  

   the 
  boundary 
  between 
  the 
  two 
  from 
  West 
  to 
  East. 
  This 
  feature 
  is 
  

   well 
  seen 
  when 
  journeying 
  from 
  Laidi 
  on 
  the 
  Than-ni 
  stream 
  to 
  

   n
