  The 
  position 
  of 
  two 
  springs 
  situated 
  in 
  the 
  valley 
  of 
  the 
  Lepan-bew 
  

   Choung 
  was 
  pointed 
  out 
  to 
  me; 
  one, 
  approximately 
  in 
  lat. 
  19° 
  16' 
  30", 
  

   long. 
  96° 
  36' 
  0", 
  the 
  other 
  situated 
  four 
  miles 
  off 
  in 
  a 
  West-south-west 
  

   direction. 
  The 
  Lepan-bew 
  Choung 
  is 
  not 
  marked 
  on 
  the 
  map, 
  but 
  it 
  is 
  a 
  

   feeder 
  of 
  the 
  Pyeng-thee-la 
  Choung 
  ; 
  indeed 
  if 
  my 
  informant 
  was 
  correct, 
  

   the 
  Lepan-bew 
  is 
  the 
  stream 
  which 
  runs 
  North 
  of 
  Than 
  Toung, 
  whilst 
  

   the 
  real 
  Pyeng-thee-la 
  is 
  the 
  unnamed 
  stream 
  shown 
  in 
  the 
  map 
  to 
  the 
  

   South 
  of 
  Than 
  Toung. 
  

  

  A 
  hot 
  spring 
  with 
  a 
  temperature 
  of 
  108° 
  rises 
  in 
  the 
  Choung-ma- 
  

   nay 
  valley, 
  lat. 
  18° 
  44' 
  0", 
  long. 
  96° 
  46' 
  0", 
  between 
  the 
  Choung-ma- 
  

   nay 
  and 
  Youk-thwah 
  streams. 
  The 
  spring 
  forms 
  a 
  pool 
  of 
  tepid 
  water, 
  

   and 
  rises 
  through 
  cracks 
  in 
  a 
  hard 
  rusty 
  sandstone, 
  much 
  indurated 
  and 
  

   resembling 
  an 
  ordinary 
  quartzitic 
  sandstone 
  of 
  the 
  Vindhyans 
  of 
  India, 
  

   but 
  a 
  member 
  probably 
  of 
  the 
  ' 
  Moulmein 
  ' 
  group 
  of 
  Dr. 
  Oldham. 
  

  

  A 
  very 
  hot 
  spring 
  rises 
  in 
  the 
  bed 
  of 
  the 
  Hlay-loo-myoung 
  Choung, 
  

   temperature 
  157, 
  lat. 
  18° 
  33* 
  0", 
  long. 
  96° 
  51' 
  0". 
  The 
  Hlay-loo 
  Choung 
  

   falls 
  into 
  the 
  Hmon 
  Choung 
  from 
  the 
  North, 
  and 
  its 
  course 
  lies 
  through 
  

   altered 
  and 
  much 
  disturbed 
  rocks 
  traversed 
  by 
  elvan 
  dykes. 
  The 
  hot 
  

   spring 
  forces 
  its 
  way 
  to 
  the 
  surface 
  at 
  several 
  spots, 
  through 
  a 
  bed 
  of 
  coarse 
  

   granitic 
  sand 
  which 
  conceals 
  the 
  actual 
  point 
  of 
  issue, 
  which 
  seems 
  to 
  be 
  

   along 
  a 
  bed 
  of 
  harsh 
  granitoid 
  appearance, 
  probably 
  a 
  highly 
  altered 
  

   member 
  of 
  the 
  above 
  Moulmein 
  group. 
  Higher 
  up 
  the 
  Hmon 
  valley 
  

   another 
  hot 
  spring 
  is 
  reported 
  to 
  occur, 
  probably 
  in 
  the 
  Yay-boo 
  Choung 
  

   of 
  the 
  Map, 
  as 
  ' 
  Yay 
  loo' 
  means 
  hot 
  spring. 
  

  

  When 
  the 
  whole 
  country 
  east 
  of 
  the 
  Sittoung 
  comes 
  to 
  be 
  ex- 
  

   amined, 
  a 
  great 
  number 
  of 
  other 
  hot 
  springs 
  will, 
  I 
  believe, 
  be 
  discovered 
  

   in 
  the 
  inner 
  hills, 
  which 
  I 
  had 
  no 
  opportunity 
  of 
  visiting. 
  

  

  Postscript.— 
  In 
  a 
  note 
  to 
  page 
  18, 
  I 
  drew 
  attention 
  to 
  the 
  dis- 
  

   crepancy 
  between 
  the 
  boundary 
  of 
  Pegu 
  as 
  laid 
  down 
  in 
  the 
  published 
  

   map 
  of 
  the 
  Province 
  and 
  the 
  Administration 
  Report 
  for 
  1868-69. 
  Since 
  

   the 
  note 
  in 
  question 
  was 
  passed 
  for 
  press, 
  I 
  have 
  seen 
  copies 
  of 
  the 
  map, 
  

  

  (
