  eoffee-colored 
  waters^ 
  almost 
  devoid 
  of 
  sediment, 
  strongly 
  contrast 
  with 
  

   the 
  surcharged 
  flood 
  waters 
  of 
  the 
  river, 
  which 
  wind 
  like 
  a 
  ribbon 
  

   of 
  another 
  color 
  through 
  them. 
  Now, 
  where 
  the 
  amount 
  of 
  deposition 
  

   under 
  subaerial 
  conditions 
  is 
  thus 
  reduced 
  to 
  a 
  minimum, 
  it 
  seems 
  to 
  me 
  

   open 
  to 
  serious 
  question 
  if 
  the 
  supposed 
  intimate 
  blending 
  of 
  one 
  year's 
  

   sedimental 
  mite 
  with 
  the 
  mites 
  of 
  preceding 
  years 
  can 
  possibly 
  take 
  

   place 
  in 
  such 
  a 
  manner 
  as 
  to 
  form 
  an 
  uniform 
  and 
  homogenous 
  deposit 
  ; 
  

   since, 
  let 
  the 
  inundations 
  subside 
  ever 
  so 
  gradually, 
  a 
  scour 
  must 
  be 
  set 
  

   up 
  on 
  the 
  subsidence 
  of 
  the 
  waters 
  proportionate 
  in 
  force 
  to 
  the 
  area 
  

   covered 
  by 
  the 
  inundation; 
  and 
  as 
  we 
  cannot 
  imagine 
  such 
  an 
  effective 
  

   inundation, 
  effective 
  that 
  is 
  to 
  the 
  extent 
  of 
  inundating 
  the 
  vast 
  area 
  

   covered 
  by 
  this 
  older 
  clay, 
  without 
  the 
  intervention 
  of 
  a 
  river 
  of 
  the 
  

   first 
  magnitude, 
  we 
  should 
  hardly 
  fail 
  to 
  find 
  traces 
  in 
  its 
  deposit, 
  of 
  those 
  

   channels 
  which 
  could 
  not 
  but 
  have 
  existed, 
  in 
  such 
  a 
  drainage 
  system 
  

   as 
  above 
  imagined. 
  Yet, 
  as 
  a 
  matter 
  of 
  fact, 
  I 
  am 
  unacquainted 
  with 
  

   any 
  such 
  channels 
  or 
  the 
  trace 
  of 
  any 
  such 
  in 
  the 
  homogenous 
  deposit 
  

   binder 
  consideration. 
  

  

  There 
  is 
  another 
  point 
  which 
  goes 
  far 
  in 
  my 
  mind 
  to 
  contravene 
  

   the 
  idea 
  of 
  the 
  older 
  clay 
  being 
  deposited 
  from 
  the 
  waters 
  of 
  the 
  Irra- 
  

   wadi 
  when 
  the 
  whole 
  country 
  was 
  at 
  a 
  lower 
  level 
  and 
  the 
  river 
  was 
  

   engaged 
  in 
  raising 
  the 
  general 
  surface 
  rather 
  than 
  in 
  deepening 
  its 
  

   channel, 
  and 
  that 
  is 
  that 
  along 
  the 
  Arakan 
  Coast 
  at 
  various 
  spots, 
  

   remnants 
  of 
  the 
  older 
  alluvium 
  can 
  be 
  detected 
  near 
  the 
  hills, 
  in 
  some 
  

   places 
  almost 
  buried 
  beneath 
  recent 
  debris 
  swept 
  down 
  by 
  torrents 
  from 
  

   the 
  adjoining 
  hill 
  sides. 
  Now, 
  these 
  remnants 
  of 
  the 
  older 
  alluvium 
  have 
  

   clearly 
  no 
  connexion 
  with 
  the 
  deposits 
  in 
  the 
  Irrawadi 
  valley 
  beyond 
  

   a 
  similarity 
  in. 
  appearance, 
  due 
  probably 
  to 
  the 
  deposits 
  skirting 
  the 
  

   ^

  est 
  base 
  of 
  the 
  Arakan 
  hills 
  being 
  derived 
  from 
  very 
  similar 
  rocks 
  to 
  

   those 
  which 
  contributed 
  towards 
  its 
  formation 
  on 
  the 
  East 
  ; 
  but 
  the 
  

   arrangement 
  of 
  these 
  remnants, 
  and 
  their 
  proximity 
  to 
  the 
  hills, 
  rather 
  

   point 
  to 
  their 
  being 
  the 
  relics 
  of 
  a 
  now 
  nearly 
  denuded 
  belt 
  of 
  clays
