  a 
  vein 
  traversing 
  the 
  altered 
  rocks, 
  and 
  is 
  here 
  associated 
  with 
  steatite 
  

   veins, 
  whence 
  the 
  name 
  of 
  the 
  hill 
  on 
  which 
  it 
  occurs, 
  Kangutoung 
  

   (steatite 
  hill) 
  .* 
  

  

  The 
  third 
  and 
  last 
  area 
  of 
  serpentine 
  outbursts 
  is 
  situated 
  along 
  

   the 
  outer 
  hills 
  West 
  of 
  Henzadah, 
  where 
  twenty-one 
  distinct 
  patches 
  

   of 
  this 
  rock 
  are 
  ranged 
  within 
  a 
  strip 
  of 
  country 
  twenty-six 
  miles 
  in 
  

   length. 
  The 
  first 
  and 
  largest 
  display 
  of 
  this 
  rock 
  is 
  a 
  broad 
  belt 
  of 
  it 
  

   crossing 
  the 
  Nungathu 
  stream 
  ; 
  the 
  last 
  and 
  smallest 
  is 
  situated 
  nine 
  

   miles 
  west 
  of 
  Ngatheingkyoung. 
  The 
  serpentine 
  occurs 
  in 
  the 
  form 
  

   of 
  small 
  hills 
  separated 
  by 
  altered 
  sandstones 
  and 
  shales, 
  and 
  ranged 
  

   along 
  the 
  outer 
  margin 
  of 
  the 
  hills. 
  No 
  dykes 
  or 
  veins 
  are 
  seen 
  here, 
  

   nor 
  is 
  the 
  alteration 
  and 
  disturbance 
  so 
  great 
  as 
  where 
  the 
  rock 
  is 
  more 
  

   largely 
  developed 
  to 
  the 
  North. 
  South 
  of 
  this, 
  no 
  serpentine 
  whatever 
  is 
  

   known 
  to 
  me. 
  The 
  serpentine 
  at 
  all 
  the 
  localities 
  above 
  described, 
  and 
  

   that 
  met 
  with 
  on 
  the 
  West 
  of 
  the 
  range, 
  and 
  also 
  near 
  Lyndi, 
  everywhere 
  

   presents 
  the 
  same 
  appearance, 
  and 
  this 
  great 
  uniformity 
  of 
  mineral 
  

   character 
  would 
  seem 
  to 
  indicate 
  community 
  of 
  origin. 
  In 
  color 
  it 
  varies 
  

   somewhat 
  from 
  a 
  pale 
  to 
  a 
  rather 
  dark, 
  but 
  not 
  dull 
  green; 
  and 
  it 
  

   would 
  yield 
  an 
  ornamental 
  stone 
  but 
  for 
  the 
  fatal 
  defect 
  of 
  being 
  every- 
  

   where 
  seamed 
  by 
  cracks 
  which 
  traverse 
  the 
  rock 
  irregularly 
  in 
  every 
  

   direction, 
  the 
  largest 
  and 
  soundest-looking 
  blocks 
  falling 
  into 
  numerous 
  

   polygonal 
  or 
  slabby 
  fragments 
  under 
  a 
  few 
  smart 
  taps 
  from 
  a 
  hammer. 
  

  

  Soapstone 
  [Kangu 
  in 
  Burmese). 
  — 
  This 
  mineral 
  which 
  is 
  used 
  by 
  the 
  

   Burmese 
  for 
  writing 
  on 
  black 
  boards, 
  is 
  largely 
  imported 
  into 
  Pegu 
  from 
  

   Upper 
  Burma, 
  but] 
  occurs 
  at 
  a 
  variety 
  of 
  spots 
  in 
  the 
  Arakan 
  range, 
  

   chiefly, 
  though 
  not 
  exclusively, 
  on 
  its 
  Eastern 
  side. 
  It 
  is 
  a 
  common 
  

   accompaniment 
  of 
  serpentine, 
  and 
  in 
  some 
  cases 
  seems 
  to 
  be 
  directly 
  

   produced 
  by 
  the 
  presence 
  of 
  that 
  rock, 
  and 
  as 
  one 
  of 
  the 
  results 
  of 
  its 
  

   action 
  on 
  the 
  stratified 
  rocks 
  in 
  contact 
  with 
  it 
  ; 
  but 
  it 
  also 
  occurs 
  in 
  

  

  * 
  Nearly 
  every 
  well 
  marked 
  hill 
  has 
  a 
  distinctive 
  name 
  among 
  the 
  Burmese; 
  not 
  one 
  

   in 
  a 
  hundred, 
  however, 
  is 
  recorded 
  in 
  the 
  map.
