  range 
  it 
  may 
  be 
  said" 
  to 
  terminate, 
  it 
  is 
  still 
  continued 
  as 
  an 
  elevated 
  

   ridge 
  of 
  ground, 
  as 
  far 
  down 
  as 
  Rangoon, 
  and 
  past 
  Syriam 
  as 
  far 
  as 
  

   Kyouktan, 
  where 
  it 
  finally 
  disappears 
  beneath 
  the 
  alluvial 
  plains 
  of 
  

   the 
  delta, 
  being 
  last 
  seen 
  in 
  some 
  rocks 
  which 
  crop 
  up 
  in 
  midchannel 
  of 
  

   the 
  Hman-won-choung. 
  

  

  According 
  to 
  Lieutenant 
  Williams 
  (Selections, 
  Records 
  of 
  the 
  Gov- 
  

   ernment 
  of 
  India 
  No. 
  XX), 
  the 
  Pegu 
  Yomah 
  attains 
  its 
  maximum 
  

   -'evation 
  of 
  3,000 
  feet 
  in 
  lat. 
  17° 
  55'. 
  From 
  this 
  to 
  the 
  frontier 
  the 
  

   height 
  varies 
  from 
  800 
  to 
  1,200 
  feet, 
  in 
  which 
  respect 
  it 
  differs 
  from 
  

   the 
  Western 
  Yomah, 
  whose 
  highest 
  portion 
  is 
  near 
  the 
  frontier, 
  which 
  

   its 
  geological 
  composition 
  may 
  help 
  to 
  explain. 
  

  

  The 
  general 
  character 
  of 
  the 
  hills 
  throughout 
  the 
  Pegu 
  Yomah 
  is 
  

   everywhere 
  much 
  the 
  same. 
  The 
  hills, 
  though 
  nowhere 
  rising 
  into 
  such 
  

   imposing 
  masses 
  as 
  may 
  be 
  seen 
  in 
  the 
  Western 
  Yomah, 
  yet, 
  as 
  a 
  rule, 
  are 
  

   extremely 
  steep, 
  and 
  the 
  valleys 
  sharply 
  excavated. 
  This 
  peculiarity 
  de- 
  

   pends 
  partly 
  on 
  the 
  soft 
  character 
  of 
  the 
  shales 
  and 
  earthy 
  sandstones 
  

   constituting 
  the 
  range, 
  and 
  partly 
  on 
  the 
  heavy 
  rainfall 
  of 
  Pegu 
  ; 
  and 
  

   but 
  for 
  the 
  protective 
  effect 
  of 
  vegetation 
  on 
  the 
  surface, 
  a 
  much 
  more 
  

   active 
  denudation 
  than 
  at 
  present 
  would 
  take 
  place. 
  

  

  The 
  Arakan, 
  or 
  Western 
  Yomah, 
  which 
  stretches 
  almost 
  uninter- 
  

   ruptedly 
  from 
  the 
  frontier 
  to 
  a 
  little 
  South 
  of 
  Cape 
  Negrais, 
  a 
  distance, 
  

   in 
  a 
  straight 
  line, 
  of 
  247 
  miles, 
  observes 
  a 
  rude 
  parallelism 
  with 
  the 
  

   Eastern 
  Yomah, 
  but 
  is 
  somewhat 
  less 
  regular, 
  forming 
  an 
  irregular 
  

   curve, 
  with 
  its 
  concavity 
  facing 
  the 
  West 
  or 
  towards 
  the 
  Bay 
  of 
  Bengal. 
  

   In 
  some 
  places, 
  as 
  West 
  of 
  Bassein, 
  and 
  again 
  further 
  to 
  the 
  South, 
  

   the 
  range 
  sinks 
  down, 
  and 
  does 
  not 
  probably 
  exceed 
  200 
  feet 
  in 
  al- 
  

   titude 
  ; 
  but 
  towards 
  the 
  frontier 
  its 
  peaks 
  attain 
  a 
  height 
  of 
  probably 
  

   double 
  that 
  of 
  the 
  highest 
  part 
  of 
  the 
  Pegu 
  Yomah, 
  and 
  some 
  of 
  them 
  

   do 
  not, 
  I 
  imagine, 
  fall 
  short 
  of 
  5,000 
  feet. 
  In 
  this, 
  the 
  Northern 
  

   part 
  of 
  the 
  Yomah, 
  the 
  mountain 
  scenery 
  is 
  remarkably 
  fine 
  and 
  

   picturesque, 
  which, 
  in 
  some 
  measure, 
  arises 
  from 
  the 
  higher 
  peaks 
  

   being 
  covered 
  with 
  grass, 
  and 
  with 
  but 
  little 
  forest 
  here 
  and 
  there
