﻿FOSSIL-

  strip 
  remains 
  resting- 
  on 
  the 
  clay, 
  with 
  fossil-wood 
  in 
  abundance 
  in 
  situ, 
  

   and 
  the 
  associated 
  nodular 
  peroxide 
  of 
  iron. 
  Over 
  the 
  remainder 
  of 
  

   the 
  area, 
  fossil-wood 
  occurs 
  in 
  scattered 
  fragments, 
  and 
  these 
  far 
  from 
  

   common. 
  Another 
  small 
  area 
  of 
  this 
  clay, 
  nine 
  miles 
  in 
  its 
  greatest 
  

   length, 
  occurs 
  near 
  Let-pan 
  -hla 
  on 
  the 
  They 
  stream, 
  which 
  falls 
  into 
  the 
  

   Bulay 
  stream 
  from 
  the 
  South 
  near 
  Tonk-kian-deing. 
  The 
  most 
  curious 
  

   physical 
  feature 
  connected 
  with 
  this 
  clay 
  area 
  is, 
  that 
  it 
  forms 
  a 
  sort 
  

   of 
  blind 
  valley 
  or 
  cul-de-sac, 
  almost 
  surrounded 
  by 
  the 
  overlying 
  sands 
  ; 
  

   the 
  sand, 
  denuded 
  from 
  what 
  now 
  constitutes 
  the 
  clay 
  area, 
  having 
  been 
  

   removed 
  by 
  the 
  seemingly 
  very 
  inadequate 
  channel 
  of 
  the 
  present 
  Let- 
  

   pan-hla 
  stream. 
  A 
  narrow 
  belt, 
  moreover, 
  of 
  this 
  sand 
  crosses 
  the 
  stream, 
  

   and 
  although 
  during 
  rain 
  an 
  efficient 
  escape 
  by 
  the 
  surface 
  channel 
  of 
  

   the 
  stream 
  takes 
  place, 
  yet 
  at 
  other 
  times, 
  the 
  surface 
  channel 
  of 
  the 
  

   stream 
  remains 
  dry, 
  the 
  feeble 
  current 
  of 
  water 
  pursuing 
  a 
  course 
  beneath 
  

   the 
  sandy 
  barrier, 
  and 
  welling 
  forth 
  again 
  only 
  when 
  this 
  belt 
  of 
  sand 
  is 
  

   passed 
  ; 
  yet, 
  along 
  and 
  across 
  the 
  line 
  of 
  this 
  bar 
  or 
  obstruction, 
  must 
  

   the 
  entire 
  mass 
  of 
  sand 
  which 
  once 
  filled 
  the 
  valley 
  of 
  Let-pan-hla, 
  

   been 
  removed 
  by 
  the 
  ordinary 
  denuding 
  powers 
  of 
  the 
  now 
  feeble 
  Let- 
  

   pan-hla 
  stream. 
  

  

  This 
  is 
  by 
  no 
  means 
  an 
  isolated 
  instance 
  of 
  a 
  stream 
  disappearing 
  

   within 
  the 
  area 
  of 
  these 
  highly 
  porous 
  upper 
  sands, 
  and 
  re-appearing 
  in 
  

   its 
  proper 
  channel 
  beyond 
  their 
  area. 
  A 
  similar 
  instance 
  is 
  seen 
  in 
  the 
  

   course 
  of 
  the 
  San 
  stream, 
  which 
  falls 
  into 
  the 
  Kyeenee 
  stream 
  near 
  the 
  

   village 
  of 
  Ooyeen. 
  Though 
  the 
  channel 
  of 
  the 
  San, 
  or 
  (as 
  it 
  is 
  also 
  

   called 
  on 
  the 
  map) 
  Kyetyongyee 
  stream, 
  is 
  a 
  broad 
  one, 
  giving 
  evidence 
  

   of 
  the 
  volume 
  of 
  water 
  it 
  discharges 
  during 
  floods, 
  yet 
  as 
  long 
  as 
  its 
  

   course 
  lies 
  within 
  the 
  fossil-wood 
  sands, 
  it 
  is 
  ordinarily 
  quite 
  devoid 
  of 
  

   water 
  ; 
  but 
  directly 
  the 
  channel 
  enters 
  • 
  the 
  area 
  of 
  the 
  underclay, 
  a 
  

   copious 
  stream 
  of 
  water 
  bubbles 
  up 
  in 
  mid-channel, 
  which 
  had 
  evidently 
  

   held 
  its 
  course 
  beneath 
  the 
  surface 
  accumulation 
  of 
  sand 
  which 
  it 
  would 
  

   seem 
  as 
  though 
  the 
  stream 
  had 
  hitherto 
  failed 
  adequately 
  to 
  clear 
  away.
