  especially 
  from

  Fossil-wood 
  sand 
  locally 
  mammaliferous. 
  — 
  The 
  sand 
  of 
  which 
  this 
  

   bed 
  is 
  mainly 
  composed 
  is 
  very 
  fine 
  and 
  uniform, 
  with 
  a 
  little 
  im- 
  

   palpable 
  argillaceous 
  matter 
  intermixed, 
  and 
  occasionally 
  a 
  few 
  small 
  

   quartz 
  pebbles. 
  In 
  the 
  cart-tracks 
  which 
  traverse 
  this 
  sand, 
  the 
  rock 
  

   breaks 
  down 
  into 
  a 
  very 
  fine 
  dust 
  most 
  fatiguing 
  to 
  travel 
  over; 
  

   and 
  in 
  the 
  beds 
  of 
  the 
  streams 
  where 
  the 
  fine 
  argillaceous 
  matter 
  

   has 
  been 
  removed, 
  a 
  fine 
  silver 
  sand 
  fills 
  the 
  entire 
  channel, 
  with 
  

   here 
  and 
  , 
  there 
  small 
  gravelly 
  banks 
  made 
  up 
  of 
  the 
  peroxide 
  of 
  iron 
  

   usually 
  associated 
  with 
  this 
  group. 
  On 
  the 
  surface 
  of 
  this 
  sand, 
  where 
  

   it 
  has 
  suffered 
  least 
  from 
  denudation, 
  fossil 
  trees 
  are 
  often 
  seen 
  scattered; 
  

   and 
  in 
  many 
  places 
  the 
  profusion 
  of 
  large 
  fragments 
  of 
  fossil-wood 
  in 
  

   situ, 
  or 
  approximately 
  so, 
  is 
  very 
  striking. 
  Over 
  the 
  whole 
  of 
  the 
  area 
  

   of 
  this 
  upper 
  sand, 
  fossil-wood 
  is 
  common, 
  in 
  the 
  form 
  of 
  angular 
  un- 
  

   rolled 
  pieces, 
  derived 
  from 
  larger 
  logs 
  by 
  simple 
  fracture 
  through 
  the 
  

   force 
  of 
  gravity, 
  or 
  spontaneous 
  disintegration 
  and 
  division 
  along 
  ori- 
  

   ginal 
  lines 
  of 
  fracture 
  and 
  weakness. 
  Opposite 
  Thayet-mio 
  behind 
  

   Yettoung 
  (especially 
  near 
  a 
  low 
  hill 
  locally 
  known 
  by 
  the 
  name 
  of 
  

   * 
  Chouk-hpew-toung' 
  or 
  c 
  white 
  stone 
  hilP 
  from 
  the 
  abundance 
  of 
  white 
  

   quartz 
  pebbles 
  scattered 
  about), 
  I 
  have 
  seen 
  trunks 
  of 
  trees, 
  some 
  40 
  or 
  

   50 
  feet 
  in 
  length, 
  stretched 
  out 
  over 
  the 
  uneven 
  surface 
  of 
  the 
  ground, 
  

   and 
  broken 
  up 
  by 
  mere 
  gravity, 
  as 
  I 
  should 
  judge, 
  into 
  fragments 
  of 
  

   about 
  four 
  or 
  five 
  feet 
  in 
  length; 
  though 
  from 
  the 
  great 
  denudation 
  

   this 
  sand 
  has 
  undergone, 
  and 
  consequent 
  displacement 
  of 
  the 
  silieified 
  

   trees, 
  the 
  more 
  usual 
  condition 
  to 
  find 
  them 
  in, 
  is 
  scattered 
  logs 
  freely 
  

   dispersed 
  over 
  the 
  surface 
  or 
  encased 
  in 
  modern 
  detritus. 
  Scarcely 
  less 
  

   plentiful 
  than 
  at 
  the 
  above 
  spot, 
  is 
  this 
  silieified 
  wood 
  South 
  of 
  Shuay- 
  

   bandor 
  and 
  between 
  Shuaybandor 
  and 
  Phoung-yo 
  to 
  the 
  South-east, 
  and 
  

   also 
  South-east 
  of 
  the 
  point 
  where 
  the 
  Kyeni 
  stream 
  crosses 
  the 
  frontier.
