﻿FOSSIL- 
  WOOD 
  GROUP. 
  77 
  

  

  beds 
  and 
  superincumbent 
  sands 
  of 
  the 
  fossil-wood 
  group. 
  These 
  sandy 
  

   beds, 
  however, 
  do 
  not 
  extend 
  south 
  of 
  the 
  Yeng-tha-le 
  Choung, 
  which 
  

   enters 
  the 
  Sittoung 
  16| 
  miles 
  below 
  the 
  frontier. 
  South 
  of 
  this, 
  these 
  

   sandy 
  beds 
  have 
  been 
  removed 
  by 
  denudation, 
  and 
  the 
  alluvium 
  is 
  thence 
  

   bounded 
  by 
  the 
  crystalline 
  and 
  gneissose 
  rocks 
  of 
  the 
  Poungloung 
  range. 
  

   East 
  of 
  the 
  village 
  of 
  Puday, 
  however, 
  a 
  small 
  outlier 
  of 
  the 
  group 
  

   has 
  survived, 
  on 
  the 
  end 
  of 
  which 
  stands 
  the 
  Kannee 
  Pagoda 
  overlooking 
  

   the 
  Sittoung, 
  and 
  a 
  little 
  further 
  south 
  a 
  more 
  considerable 
  outlier 
  which 
  

   stretches 
  below 
  Tonghoo 
  to 
  close 
  on 
  the 
  banks 
  of 
  the 
  Thonk-yay-gat 
  

   river. 
  These 
  two 
  outliers 
  are, 
  lithologically 
  considered, 
  typical 
  laterite, 
  

   distinguishable 
  only 
  from 
  the 
  great 
  belt 
  of 
  laterite 
  met 
  with 
  South 
  of 
  

   Kyouk-kyee, 
  by 
  being 
  in 
  places 
  charged 
  with 
  huge 
  boulders 
  which 
  greatly 
  

   reduce 
  the 
  lateritic 
  cement 
  wherein 
  they 
  are 
  embedded 
  ; 
  but 
  a 
  close 
  ex- 
  

   amination 
  of 
  these 
  interesting 
  deposits 
  has 
  convinced 
  me, 
  that 
  geolo- 
  

   gically 
  speaking, 
  they 
  are 
  portions 
  of 
  the 
  fossil-wood 
  group, 
  and 
  the 
  

   extreme 
  termination 
  of 
  the 
  group 
  to 
  the 
  South, 
  on 
  the 
  Eastern 
  side 
  of 
  

   the 
  Sittoung, 
  denudation 
  having 
  entirely 
  swept 
  away 
  the 
  group 
  on 
  that 
  

   side 
  of 
  the 
  river, 
  below 
  the 
  junction 
  of 
  the 
  Thouk-yay-gat 
  in 
  Lat. 
  

   18° 
  53'. 
  The 
  lithological 
  constitution 
  of 
  both 
  these 
  outliers 
  is 
  the 
  same, 
  

   and 
  to 
  it 
  in 
  part 
  may 
  be 
  due 
  their 
  preservation, 
  when 
  the 
  less 
  coherent 
  

   portion 
  of 
  the 
  group 
  was 
  removed 
  by 
  denudation. 
  The 
  bulk 
  of 
  the 
  

   deposit 
  may 
  be 
  described 
  as 
  a 
  sandy 
  clay, 
  differing 
  but 
  little 
  from 
  that 
  

   met 
  with 
  to 
  the 
  North 
  of 
  the 
  Sittoung 
  within 
  the 
  area 
  of 
  this 
  group; 
  but 
  

   an 
  additional 
  feature 
  it 
  here 
  presents, 
  is 
  the 
  great 
  number 
  of 
  pebbles 
  

   contained 
  in 
  it, 
  which 
  weathering 
  out, 
  give 
  the 
  appearance 
  of 
  the 
  country 
  

   being 
  composed 
  of 
  gravel 
  beds 
  ; 
  where, 
  however, 
  a 
  section 
  is 
  displayed, 
  it 
  

   is 
  seen 
  that 
  the 
  gravel 
  is 
  merely 
  a 
  surface 
  accumulation, 
  the 
  result 
  of 
  denu- 
  

   dation, 
  which 
  has 
  removed 
  the 
  finer 
  sand 
  and 
  clay 
  and 
  left 
  the 
  surface 
  

   encumbered 
  with 
  the 
  pebbles 
  originally 
  disseminated 
  through 
  the 
  bulk 
  of 
  

   the 
  rock. 
  This 
  can 
  be 
  well 
  seen 
  along 
  the 
  line 
  of 
  road 
  between 
  Kannee 
  

   and 
  Kon-meng-eing 
  and 
  thence 
  to 
  Paday. 
  The 
  same 
  may 
  be 
  said 
  of
