  main 
  line 
  of 
  the 
  range 
  : 
  — 
  " 
  It 
  is 
  situated 
  between 
  the 
  sources 
  of 
  the 
  Hlowah 
  

   and 
  Paymyouk 
  streams, 
  and 
  marks 
  a 
  remarkable 
  change 
  in 
  the 
  Arakan 
  

   Range, 
  of 
  which 
  in 
  some 
  respects 
  it 
  is 
  the 
  culminant 
  peak. 
  Instead, 
  

   however, 
  of 
  the 
  range 
  continuing 
  its 
  course 
  Northward 
  past 
  Shuay-doung, 
  

   it 
  here 
  takes 
  a 
  sharp 
  sigmoid 
  curve 
  to 
  the 
  Westward 
  before 
  again 
  tending 
  

   North, 
  giving 
  thereby 
  the 
  appearance 
  to 
  Shuay-doung 
  of 
  standing 
  out 
  

   from 
  the 
  main 
  range, 
  like 
  a 
  promontory, 
  round 
  which 
  the 
  sources 
  of 
  

   the 
  Hlowah 
  wind, 
  so 
  that 
  the 
  drainage 
  pertaining 
  to 
  the 
  mountain, 
  

   received 
  by 
  the 
  Hlowah 
  and 
  Paymyouk 
  streams, 
  represents 
  an 
  arc 
  of 
  no 
  

   less 
  than 
  300 
  degrees 
  at 
  least, 
  with 
  the 
  hill 
  as 
  a 
  centre.'" 
  

  

  Prom 
  Shuay-doung 
  as 
  far 
  down 
  as 
  where 
  the 
  Tonghoop 
  road 
  crosses 
  

   the 
  range, 
  a 
  distance 
  of 
  38 
  miles, 
  the 
  range 
  tends 
  South-south-east. 
  South 
  

   of 
  the 
  Tonghoop 
  road 
  as 
  far 
  as 
  Lat. 
  17° 
  30', 
  a 
  distance 
  of 
  78 
  miles, 
  the 
  

   general 
  direction 
  of 
  the 
  range 
  is 
  South, 
  veering 
  round 
  for 
  the 
  rest 
  of 
  

   its 
  length 
  as 
  far 
  as 
  Hmandeng 
  or 
  Pagoda 
  Point, 
  a 
  distance 
  of 
  114 
  miles, 
  

   to 
  South-south-west, 
  though 
  its 
  direction 
  is 
  not 
  quite 
  regular 
  over 
  the 
  

   entire 
  distance. 
  The 
  elevation 
  of 
  the 
  Western 
  Yomah 
  has 
  been 
  ap- 
  

   proximately 
  determined 
  at 
  a 
  few 
  points 
  South 
  of 
  the 
  frontier. 
  Near 
  

   the 
  frontier 
  some 
  peaks 
  do 
  not 
  probably 
  fall 
  short 
  of 
  5,000 
  feet 
  in 
  

   height, 
  but 
  South 
  of 
  Shuay-doung 
  a 
  diminution 
  occurs 
  in 
  this 
  respect, 
  

   and 
  at 
  the 
  Tonghoop 
  road, 
  the 
  highest 
  peak, 
  Shoukben-toung, 
  is 
  only 
  

   3,200. 
  Opposite 
  Myanoung, 
  the 
  peak 
  of 
  Sab-ka-pon-toung 
  is 
  4,003 
  feet 
  

   (the 
  highest 
  peak 
  that 
  has 
  been 
  measured) 
  , 
  whence 
  the 
  height 
  rapidly 
  

   diminishes, 
  till 
  in 
  Lat. 
  17° 
  30' 
  the 
  mean 
  height 
  of 
  the 
  peaks 
  would 
  seem 
  

   to 
  be 
  about 
  1,400. 
  South 
  of 
  this, 
  the 
  range 
  steadily 
  decreases 
  in 
  height. 
  

   West 
  of 
  Gna-theing-khyoung 
  it 
  is 
  only 
  892 
  feet, 
  and 
  25 
  miles 
  further 
  

   South, 
  on 
  the 
  Baumi 
  Pass, 
  this 
  is 
  reduced 
  to 
  only 
  270 
  feet. 
  South 
  of 
  

   this 
  to 
  Pagoda 
  Point 
  the 
  height 
  ranges 
  between 
  200 
  and 
  400 
  feet, 
  in 
  

   some 
  spots 
  probably 
  falling 
  below 
  even 
  200 
  ; 
  the 
  lofty 
  forest 
  vegetation, 
  

   however, 
  greatly 
  interferes 
  with 
  anything 
  like 
  a 
  general 
  view 
  of 
  the 
  

   country 
  at 
  such 
  low 
  elevations 
  as 
  these.
