  This 
  bed 
  recurs 
  on 
  Long 
  Island 
  and 
  in 
  several 
  places 
  farther 
  North, 
  

   the 
  most 
  Northerly 
  locality 
  noticed 
  being 
  near 
  the 
  village 
  of 
  Kya-bon, 
  

   South-west 
  of 
  Nga-theing-kyoung, 
  where 
  considerable 
  quantities 
  of 
  the 
  

   stone 
  are 
  extracted 
  for 
  the 
  purpose 
  of 
  carving 
  into 
  images 
  of 
  Gaudama." 
  

   This 
  stone, 
  which 
  is 
  locally 
  used 
  in 
  Southern 
  Pegu 
  in 
  place 
  of 
  the 
  

   crystalline 
  marble 
  of 
  which 
  images 
  are 
  made 
  in 
  Upper 
  Burma, 
  is 
  called 
  

   ' 
  andagu 
  hyonh* 
  or 
  image-stone, 
  and 
  extends 
  a 
  little 
  higher 
  than 
  stated 
  

   above 
  ; 
  the 
  most 
  Northerly 
  point 
  known 
  to 
  me 
  being 
  in 
  the 
  bed 
  of 
  a 
  

   stream 
  falling 
  into 
  the 
  Nunga-thu-khoung, 
  near 
  Endeingon, 
  some 
  

   twenty-six 
  miles 
  North 
  of 
  Nga-theing-kyoung, 
  and 
  in 
  about 
  the 
  

   parallel 
  of 
  17° 
  45'. 
  It 
  is 
  merely 
  exposed 
  here 
  in 
  the 
  bed 
  of 
  the 
  stream, 
  

   and 
  it 
  is 
  possible 
  Mr. 
  Blanford's 
  words 
  may 
  allude 
  to 
  the 
  furthest 
  point 
  

   to 
  the 
  North 
  at 
  which 
  quarries 
  of 
  it 
  are 
  worked. 
  „As 
  the 
  beds 
  here 
  are 
  

   much 
  masked 
  by 
  gravelly 
  accumulations, 
  these 
  beds 
  probably 
  extend 
  

   still 
  farther 
  to 
  the 
  North, 
  but 
  I 
  am 
  acquainted 
  with 
  nothing 
  analogous 
  

   to 
  them 
  in 
  the 
  Prome 
  district, 
  and 
  am 
  inclined 
  to 
  regard 
  them 
  as 
  local 
  

   deposits 
  which 
  never 
  extended 
  much 
  beyond 
  the 
  district 
  of 
  Bassein. 
  

   Their 
  position 
  with 
  regard 
  to 
  the 
  limestone 
  is 
  doubtful, 
  but 
  they 
  

   probably 
  come 
  in 
  above 
  it 
  and 
  constitute 
  the 
  highest 
  member 
  of 
  the 
  

   group. 
  

  

  Between 
  Gyo-gon 
  on 
  the 
  Kyet-toung 
  stream 
  and 
  Shan-gha-yet 
  

   a 
  thick 
  bed 
  of 
  soft 
  argillaceous 
  sandstone, 
  evidently 
  one 
  of 
  the 
  Andagu 
  

   kyouk 
  series, 
  rises 
  up 
  in 
  the 
  jungle 
  in 
  the 
  form 
  of 
  rounded 
  blocks 
  

   which 
  the 
  Burmese 
  term 
  ' 
  Amwa-ko 
  theing 
  5 
  and 
  regard 
  as 
  a 
  herd 
  of 
  

   elephants 
  turned 
  to 
  stone. 
  The 
  peculiar 
  mode 
  of 
  weathering 
  of 
  the 
  

   argillaceous 
  beds 
  of 
  this 
  group 
  is 
  due 
  to 
  their 
  composition, 
  which 
  causes 
  

   them 
  to 
  crack 
  spontaneously 
  and 
  desquamate 
  under 
  atmospheric 
  action. 
  

   This 
  habit 
  of 
  the 
  rock 
  may 
  be 
  conveniently 
  termed 
  the 
  ' 
  amylaceous,' 
  

   from 
  resembling 
  the 
  manner 
  in 
  which 
  starch 
  shrinks 
  and 
  cracks 
  in 
  

   drying 
  ; 
  and 
  it 
  is 
  a 
  similar 
  tendency, 
  in 
  some 
  of 
  the 
  finer 
  and 
  more 
  

   homogeneous 
  beds 
  of 
  this 
  division, 
  to 
  break 
  up 
  into 
  cuboidal 
  masses
