﻿NEGRAIS 
  ROCKS.

  appears, 
  however, 
  to 
  remain 
  Easterly 
  till 
  the 
  axis 
  of 
  the 
  main 
  range 
  is 
  

   crossed. 
  

  

  The 
  axis 
  of 
  the 
  range 
  here 
  consists 
  of 
  a 
  great 
  thickness 
  of 
  beds 
  of 
  a 
  

   very 
  homogeneous 
  clay, 
  of 
  a 
  reddish 
  or 
  pinky 
  yellow 
  color, 
  and. 
  

   obscurely 
  bedded. 
  It 
  is 
  much 
  broken 
  up 
  and 
  comminuted 
  as 
  though 
  

   through 
  severe 
  pressure, 
  but 
  little 
  altered, 
  and 
  neither 
  to 
  the 
  Eastward 
  

   nor 
  Westward 
  are 
  its 
  relations 
  with 
  the 
  other 
  rocks 
  well 
  seen. 
  After 
  

   crossing 
  the 
  axis 
  of 
  the 
  range, 
  the 
  succession 
  of 
  beds 
  was 
  not 
  well 
  seen 
  ; 
  

   and 
  though 
  I 
  did 
  not 
  remark 
  the 
  silicious 
  beds 
  to 
  be 
  so 
  prominent 
  as 
  on 
  the 
  

   East 
  of 
  the 
  range, 
  I 
  am 
  inclined 
  to 
  believe 
  that 
  the 
  same 
  beds 
  as 
  are 
  met 
  

   with 
  in 
  the 
  East 
  are 
  again 
  crossed 
  on 
  the 
  West, 
  in 
  a 
  reverse 
  order, 
  that 
  

   is 
  to 
  say, 
  that 
  the 
  range 
  forms 
  a 
  great 
  anticlinal, 
  the 
  prevailing 
  dips 
  

   on 
  its 
  Eastern 
  side 
  being 
  Easterly, 
  and 
  on 
  its 
  Western 
  side 
  Westerly. 
  On 
  

   the 
  West, 
  however, 
  there 
  is 
  ( 
  locally 
  at 
  all 
  events) 
  greater 
  irregularity 
  in 
  

   dip 
  and 
  strike 
  than 
  on 
  the 
  East 
  ; 
  and 
  I 
  have 
  there 
  noticed 
  beds 
  with 
  an 
  

   East 
  and 
  West 
  strike, 
  or 
  nearly 
  at 
  right 
  angles 
  to 
  the 
  prevailing 
  one 
  

   of 
  the 
  range. 
  Much 
  allowance 
  must 
  be 
  made 
  for 
  imperfect 
  observation, 
  

   as 
  all 
  one 
  sees 
  of 
  the 
  rock 
  is 
  such 
  glimpses 
  as 
  can 
  be 
  obtained 
  along 
  

   the 
  narrow 
  path 
  threading 
  these 
  forest-clad 
  ranges. 
  When 
  well 
  past 
  

   the 
  main 
  range, 
  the 
  road 
  descends 
  and 
  runs 
  over 
  a 
  thick 
  succession 
  of 
  

   the 
  but 
  little 
  altered 
  sandstones 
  of 
  the 
  Kyouk-gyee 
  (big 
  stone) 
  stream. 
  

   Part 
  of 
  this 
  rocky 
  stream 
  is 
  quite 
  impassable 
  for 
  elephants, 
  and 
  the 
  

   nature 
  of 
  the 
  country 
  may 
  be 
  imagined 
  from 
  it 
  requiring 
  four 
  hard 
  days' 
  

   marches 
  to 
  accomplish 
  the 
  distance 
  from 
  Nyoung-ben-tha 
  to 
  Yaypot, 
  

   though 
  these 
  villages 
  are 
  in 
  a 
  direct 
  line 
  only 
  fifteen 
  miles 
  apart. 
  

  

  A 
  little 
  south 
  of 
  Phon-sa-khyoung, 
  near 
  Matha 
  on 
  the 
  coast, 
  a 
  

   good 
  section 
  of 
  beds 
  of 
  this 
  group 
  is 
  seen 
  ; 
  but 
  their 
  proper 
  place 
  in 
  the 
  

   series 
  can 
  hardly 
  be 
  determined 
  owing 
  to 
  the 
  want 
  of 
  any 
  sort 
  of 
  geolo- 
  

   gical 
  horizon 
  in 
  the 
  group, 
  either 
  lithological 
  or 
  otherwise. 
  I 
  am 
  in- 
  

   clined, 
  however, 
  to 
  place 
  them 
  high 
  in 
  the 
  series, 
  and 
  above 
  the 
  vast 
  series 
  

  

  of 
  sandstones 
  seen 
  above 
  Yaypot, 
  in 
  the 
  bed 
  of 
  the 
  Kyouk-gyee 
  stream,
