  These 
  beds 
  occur 
  on 
  no 
  other 
  part 
  of 
  the 
  coast, 
  but 
  exist 
  here 
  in 
  

   a 
  position 
  very 
  favorable 
  for 
  working-. 
  Koranji 
  island 
  is 
  composed 
  of 
  

   these 
  beds 
  (which 
  I 
  have 
  already 
  described), 
  and 
  under 
  its 
  lee 
  side 
  

   a 
  channel 
  exists, 
  having- 
  a 
  depth 
  of 
  two 
  or 
  three 
  fathoms 
  at 
  low 
  

   water, 
  with 
  good 
  bottom 
  of 
  sand 
  or 
  mud. 
  The 
  channel 
  shoals 
  gradually 
  

   towards 
  the 
  mainland, 
  and 
  is 
  protected 
  by 
  Koranji 
  island 
  on 
  the 
  West 
  

   or 
  seaward, 
  and 
  by 
  a 
  bar 
  almost 
  dry 
  at 
  low 
  water 
  to 
  the 
  North, 
  but 
  enjoy- 
  

   ing 
  always 
  a 
  safe 
  and 
  easy 
  entrance 
  from 
  the 
  South, 
  save 
  during 
  the 
  

   prevalence 
  of 
  the 
  South-west 
  monsoon, 
  when 
  all 
  coasting 
  traffic 
  is 
  

   given 
  up. 
  Three 
  miles, 
  however, 
  East-by-south 
  from 
  Nga-tha-mu 
  is 
  the 
  

   large 
  village 
  of 
  Nga-got-kweng, 
  on 
  a 
  well 
  sheltered 
  tidal 
  creek, 
  at 
  the 
  

   mouth 
  of 
  which 
  (being 
  quite 
  sheltered 
  to 
  the 
  South) 
  shipments 
  of 
  stone 
  

   of 
  the 
  same 
  description 
  might 
  be 
  made 
  throughout 
  the 
  year. 
  

  

  Clays. 
  — 
  The 
  clay 
  in 
  ordinary 
  use 
  for 
  pottery 
  and 
  brick-making 
  is 
  

   the 
  ordinary 
  alluvial 
  clay 
  of 
  the 
  province, 
  which 
  receives 
  no 
  preparation 
  

   beyond 
  mixing 
  with 
  water 
  before 
  it 
  is 
  moulded. 
  A 
  dark-colored 
  seam 
  

   in 
  the 
  alluvium, 
  which 
  within 
  the 
  tidal 
  portion 
  of 
  the 
  delta 
  is 
  below 
  

   high 
  water 
  mark, 
  is 
  much 
  sought 
  for 
  by 
  potters 
  for 
  their 
  vessels, 
  but 
  

   the 
  seam 
  is 
  a 
  thin 
  one, 
  and 
  the 
  clay, 
  save 
  in 
  its 
  darker 
  color, 
  seems 
  iden- 
  

   tical 
  with 
  the 
  common 
  sort. 
  Some 
  of 
  the 
  upper 
  beds 
  of 
  the 
  Nummulitie 
  

   group, 
  already 
  described, 
  consist 
  mainly 
  of 
  china-clay, 
  and 
  would 
  answer 
  

   well 
  for 
  the 
  manufacture 
  of 
  chinaware, 
  being 
  almost 
  free 
  from 
  iron. 
  No 
  

   practical 
  experiments 
  have 
  as 
  yet 
  been 
  made 
  with 
  any 
  of 
  the 
  clays 
  of 
  Pegu, 
  

   and 
  so 
  ill 
  directed 
  and 
  unsuccessful 
  have 
  the 
  attempts 
  been 
  to 
  make 
  

   even 
  good 
  ordinary 
  bricks 
  that 
  I 
  understand 
  the 
  Department 
  of 
  Public 
  

   Works 
  has 
  even 
  imported 
  Calcutta-made 
  bricks 
  for 
  use 
  in 
  Rangoon. 
  

   One 
  thing 
  I 
  can 
  assert 
  of 
  my 
  own 
  knowledge, 
  that 
  I 
  have 
  seen 
  bricks 
  

   about 
  to 
  be 
  used 
  in 
  Government 
  buildings 
  in 
  Pegu, 
  portions 
  of 
  which 
  

   might 
  be 
  crumbled 
  to 
  powder 
  between 
  the 
  finger 
  and 
  thumb, 
  but 
  this 
  is 
  

   not 
  because 
  no 
  good 
  bricks 
  can 
  be 
  made 
  in 
  the 
  province, 
  but 
  from 
  the 
  

   difficulty 
  of 
  securing 
  uniformity 
  of 
  excellence 
  from 
  native 
  contractors,
