  surface 
  accumulation's 
  may 
  be 
  detected 
  along- 
  the 
  line 
  of 
  the 
  outer 
  skirts 
  

   of 
  the 
  Pegu 
  Yomah, 
  after 
  leaving 
  Rangoon, 
  long 
  before 
  the 
  principal 
  

   remnants 
  of 
  the 
  beds 
  still 
  existing 
  are 
  met 
  with 
  in 
  Eastern 
  Prome. 
  On 
  

   the 
  Eastern 
  or 
  Martaban 
  side, 
  however, 
  of 
  the 
  Pegu 
  Yomah, 
  the 
  removal 
  

   of 
  the 
  fossil- 
  wood 
  sand 
  appears 
  to 
  have 
  been 
  more 
  complete 
  ; 
  as 
  I 
  not 
  

   only 
  failed 
  to 
  find 
  any 
  fragments 
  of 
  fossil-wood 
  myself, 
  but 
  ascer- 
  

   tained 
  by 
  repeated 
  enquiries 
  that 
  none 
  such 
  were 
  known 
  to 
  occur 
  to 
  the 
  

   villagers, 
  who 
  are 
  perfectly 
  familiar 
  with 
  the 
  silicified 
  wood 
  or 
  c 
  Engyn- 
  

   chouk' 
  from 
  the 
  use 
  which 
  is 
  made 
  of 
  it, 
  as 
  a 
  substitute 
  for 
  flint, 
  wher- 
  

   ever 
  it 
  occurs. 
  On 
  nearing 
  from 
  the 
  South, 
  the 
  banks 
  of 
  the 
  Kaboung 
  

   Choung, 
  which 
  falls 
  into 
  the 
  Sittoung 
  a 
  little 
  below 
  Tonghoo, 
  near 
  

   Lat. 
  18°53', 
  I 
  first 
  heard 
  of 
  fossil-wood, 
  which, 
  I 
  was 
  told, 
  occurred 
  

   not 
  rarely 
  Northwards 
  of 
  the 
  Kaboung; 
  and 
  I 
  first 
  detected 
  small 
  

   fragments 
  of 
  fossil-wood 
  within 
  a 
  few 
  miles 
  of 
  the 
  Kaboung 
  on 
  its 
  

   right 
  or 
  Southern 
  bank, 
  where, 
  however, 
  such 
  fragments 
  are 
  scarce 
  and 
  

   small. 
  Crossing 
  the 
  Kaboung, 
  at 
  a 
  spot 
  about 
  two 
  miles 
  North-west 
  

   of 
  Tha-bhet-kway, 
  and 
  fifteen 
  miles 
  West 
  of 
  the 
  confluence 
  of 
  the 
  

   Kaboung, 
  large 
  masses 
  of 
  fossil-wood 
  are 
  seen 
  scattered 
  over 
  the 
  hill 
  

   side, 
  some 
  of 
  which 
  are 
  three 
  or 
  four 
  feet 
  in 
  length, 
  and 
  derived 
  

   apparently 
  from 
  a 
  single 
  huge 
  stem 
  broken 
  in 
  pieces 
  by 
  its 
  own 
  weight, 
  

   as 
  the 
  soft 
  sand 
  in 
  which 
  it 
  was 
  originally 
  entombed 
  was 
  removed 
  in 
  

   an 
  irregular 
  manner 
  by 
  atmospheric 
  action. 
  From 
  this 
  place, 
  for 
  a 
  

   distance 
  of 
  twenty-five 
  miles 
  Northwards, 
  fossil-wood 
  is 
  not 
  rare, 
  at 
  a 
  

   variety 
  of 
  spots 
  scattered 
  in 
  the 
  outer 
  hills 
  ; 
  after 
  which, 
  though 
  the 
  

   same 
  beds 
  seem 
  to 
  prevail 
  to 
  the 
  frontier, 
  the 
  fossil-wood 
  is 
  absent. 
  As 
  

   a 
  rule, 
  the 
  uppermost 
  or 
  fossil-wood 
  beds 
  are 
  chiefly 
  met 
  with 
  along 
  

   the 
  outer 
  hills, 
  giving 
  place 
  by 
  degrees 
  as 
  we 
  proceed 
  West 
  to 
  the 
  

   underlying 
  beds 
  of 
  the 
  Prome 
  group; 
  but 
  near 
  the 
  frontier, 
  in 
  the 
  

   Magoo 
  Choung 
  just 
  above 
  its 
  junction 
  with 
  the* 
  Choung-ma-nay 
  

  

  * 
  The 
  names 
  Magoo 
  and 
  Choung-ma-nay 
  are 
  not 
  given 
  in 
  the 
  map, 
  but 
  the 
  former 
  

   nearly 
  corresponds 
  in 
  general 
  position 
  with 
  the 
  stream 
  called 
  Hso-kay 
  Choung 
  (one 
  probably 
  

   being 
  an 
  affluent 
  of 
  the 
  other), 
  whilst 
  the 
  Choung-ma-nay 
  is 
  probably 
  identical 
  with 
  the 
  

   Kyouk-ma-hseng 
  Choung 
  of 
  the 
  map.
