﻿FOSSIL-WOOD 
  GROUP. 
  61 
  

  

  bably 
  resulted 
  from 
  the 
  denudation 
  of 
  the 
  group, 
  and 
  the 
  former 
  exten- 
  

   sion 
  of 
  the 
  fossil-wood 
  group 
  on 
  the 
  East 
  of 
  the 
  Irrawadi, 
  as 
  I 
  think 
  it 
  

   must 
  be 
  admitted, 
  as 
  far 
  South 
  as 
  Rangoon. 
  

  

  East 
  of 
  the 
  Irrawadi 
  the 
  fossil-wood 
  group 
  covers 
  a 
  very 
  consider- 
  

   able, 
  but 
  irregular 
  and 
  indented 
  area, 
  from 
  the 
  frontier, 
  to 
  a 
  little 
  below 
  

   the 
  parallel 
  of 
  Padoung. 
  The 
  group 
  has 
  been 
  everywhere 
  so 
  extensively 
  

   denuded 
  that 
  little 
  now 
  remains 
  of 
  the 
  upper 
  portion; 
  though 
  from 
  

   the 
  indestructible 
  character 
  of 
  much 
  of 
  the 
  fossil-wood 
  so 
  plentifully 
  

   distributed 
  through 
  it, 
  the 
  former 
  extension 
  of 
  the 
  group 
  may 
  be 
  traced 
  

   over 
  an 
  area 
  wherein 
  the 
  greater 
  portion 
  has 
  undergone 
  complete 
  re- 
  

   moval. 
  South 
  of 
  the 
  parallel 
  of 
  Padoung 
  no 
  very 
  reliable 
  proofs 
  occur 
  of 
  

   the 
  existence 
  at 
  present 
  of 
  the 
  undisturbed 
  beds 
  of 
  this 
  group 
  ; 
  but 
  its 
  

   former 
  extension, 
  even 
  as 
  far 
  South 
  as 
  Rangoon, 
  is 
  proved 
  by 
  the 
  occa- 
  

   sional 
  occurrence 
  of 
  partly 
  rolled 
  pieces 
  of 
  fossil- 
  wood 
  in 
  the 
  gravelly 
  de- 
  

   tritus 
  which 
  to 
  the 
  South 
  covers 
  up 
  the 
  undisturbed 
  beds 
  of 
  the 
  group, 
  

   and 
  in 
  a 
  measure 
  replaces 
  them 
  along 
  the 
  outer 
  hills. 
  As 
  an 
  instance 
  

   in 
  point, 
  I 
  may 
  quote 
  the 
  occurrence 
  of 
  a 
  log 
  of 
  silicified 
  wood, 
  some 
  

   four 
  feet 
  in 
  length, 
  between 
  the 
  Oakkan 
  and 
  Thonsay 
  streams, 
  fully 
  sixty- 
  

   five 
  miles 
  South 
  of 
  the 
  point 
  where 
  the 
  undisturbed 
  beds 
  of 
  the 
  fossil- 
  

   wood 
  group 
  at 
  present 
  terminate. 
  The 
  log 
  occurs 
  in 
  a 
  sequestered 
  spot 
  

   in 
  dense 
  jungle, 
  half 
  embedded 
  in 
  sandy 
  detritus, 
  which 
  I 
  regard 
  as 
  

   derived 
  from 
  the 
  waste 
  and 
  re-arrangement 
  of 
  the 
  fossil- 
  wood 
  sands 
  in 
  

   the 
  immediate 
  vicinity 
  ; 
  since 
  a 
  log 
  of 
  this 
  size 
  could 
  not 
  have 
  suffered 
  

   transport 
  from 
  any 
  distance, 
  and 
  there 
  is 
  no 
  reason 
  to 
  suppose, 
  that 
  it 
  is 
  

   not 
  now 
  in 
  very 
  nearly 
  the 
  same 
  position 
  it 
  originally 
  occupied 
  when 
  

   the 
  bed 
  wherein 
  it 
  was 
  first 
  deposited 
  was 
  removed 
  by 
  atmospheric 
  denu- 
  

   dation. 
  Smaller 
  pieces 
  than 
  the 
  above 
  log 
  are 
  not 
  uncommon, 
  and 
  are 
  

   to 
  be 
  found 
  even 
  in 
  the 
  immediate 
  neighbourhood 
  of 
  Rangoon. 
  When 
  

   I 
  first 
  heard 
  of 
  the 
  occurrence 
  of 
  fragments 
  of 
  silicified 
  wood 
  in 
  the 
  

   low 
  undulating 
  ground 
  near 
  the 
  so-called 
  ' 
  Lakes' 
  near 
  Rangoon, 
  I 
  

   felt 
  inclined 
  to 
  attribute 
  their 
  occurrence 
  to 
  the 
  agency 
  of 
  the 
  Burmese,
