  and 
  desquamate 
  spontaneously 
  at 
  exposed 
  corners, 
  that 
  interferes 
  with 
  

   the 
  use 
  of 
  the 
  stone 
  for 
  ornamental 
  carvings, 
  for 
  which 
  purpose 
  its 
  

   fineness 
  of 
  grain 
  and 
  softness 
  would 
  seem 
  to 
  recommend 
  it. 
  For 
  

   internal 
  work, 
  however, 
  in 
  places 
  protected 
  from 
  the 
  weather, 
  it 
  would 
  

   probably 
  answer 
  well. 
  The 
  ' 
  Andagukyouk' 
  selected 
  by 
  the 
  Burmese 
  for 
  

   carving 
  purposes, 
  is 
  a 
  very 
  homogeneous, 
  cream-colored 
  rock, 
  which 
  is 
  

   thus 
  described 
  by 
  Mr. 
  Blanford 
  : 
  — 
  " 
  The 
  stone 
  is 
  obtained 
  from 
  the 
  quarry 
  

   in 
  blocks 
  generally 
  about 
  eighteen 
  inches 
  high, 
  by 
  a 
  foot 
  broad 
  at 
  the 
  

   base, 
  and 
  four 
  or 
  five 
  inches 
  thick. 
  These 
  are 
  said 
  to 
  be 
  sold 
  to 
  the 
  

   image 
  carvers 
  at 
  the 
  price 
  of 
  fifteen 
  rupees 
  the 
  hundred. 
  The 
  rock 
  is 
  

   very 
  soft, 
  resembling 
  chalk 
  in 
  consistency, 
  and 
  its 
  extraction 
  and 
  carv- 
  

   ing 
  are 
  easy." 
  An 
  unusually 
  light 
  and 
  pure 
  specimen 
  from 
  near 
  Endein- 
  

   gon 
  was 
  found 
  by 
  Mr. 
  Tween 
  to 
  be

  West 
  of 
  the 
  Arakan 
  range, 
  I 
  have 
  no 
  certain 
  knowledge 
  of 
  the 
  oc- 
  

   currence 
  of 
  these 
  'andagu-kyouk' 
  beds 
  ; 
  but 
  near 
  Kyeantalee, 
  in 
  a 
  swampy 
  

   spot 
  on 
  the 
  South 
  bank 
  of 
  the 
  Kyeantalee 
  river, 
  near 
  Sande, 
  an 
  outcrop 
  

   occurs 
  of 
  a 
  white 
  argillaceous 
  rock 
  which 
  may 
  represent 
  a 
  bed 
  of 
  this 
  group, 
  

   the 
  more 
  probably 
  so, 
  from 
  its 
  occurring 
  near 
  a 
  small 
  outcrop 
  of 
  

   Nummulitic 
  limestone, 
  close 
  to 
  Pandua 
  (a 
  village 
  not 
  on 
  the 
  map) 
  . 
  

  

  Having 
  described 
  the 
  arrangement 
  and 
  extent 
  of 
  the 
  Nummulitic 
  

   group 
  along 
  the 
  flanks 
  of 
  the 
  Arakan 
  range, 
  it 
  only 
  remains 
  to 
  add 
  a 
  

   few 
  words 
  regarding 
  an 
  outlier 
  of 
  this 
  formation 
  which 
  at 
  one 
  time 
  

   attracted 
  considerable 
  attention 
  on 
  account 
  of 
  a 
  small 
  deposit 
  of 
  coal 
  

   which 
  it 
  contained, 
  but 
  which 
  did 
  not 
  fulfil 
  the 
  expectations 
  entertaiued 
  

   regarding 
  it.
