  OLDHAM: 
  GREAT 
  EARTHQUAKE 
  OF 
  1 
  897. 
  

  

  above, 
  below, 
  and 
  where 
  it 
  could 
  be 
  seen 
  under, 
  the 
  waters 
  

   of 
  the 
  lake, 
  it 
  must 
  have 
  had 
  a 
  fall 
  of 
  about 
  200 
  feet 
  per 
  mile. 
  

   Taking 
  only 
  one 
  half 
  of 
  this 
  as 
  the 
  actual 
  fall, 
  between 
  the 
  deepest 
  

   part 
  of 
  the 
  lake 
  and 
  the 
  outlet, 
  there 
  must 
  have 
  been 
  originally 
  a 
  

   difference 
  of 
  12 
  feet 
  in 
  level, 
  and 
  as" 
  the 
  point 
  which 
  was 
  formerly 
  the 
  

   higher 
  by 
  at 
  least 
  12 
  feet 
  is 
  now 
  the 
  lower 
  by 
  the 
  same 
  amount, 
  we 
  

   reach 
  the 
  conclusion 
  that 
  the 
  total 
  change 
  of 
  levels 
  cannot 
  be 
  less 
  

   than 
  24 
  feet. 
  

  

  About 
  a 
  mile 
  and 
  a 
  half 
  above 
  this 
  is 
  another 
  pool 
  of 
  similar 
  

   character, 
  though 
  not 
  so 
  long 
  or 
  deep, 
  and 
  about 
  three-quarters 
  of 
  a 
  

   mile 
  further 
  up 
  is 
  the 
  lower 
  end 
  of 
  another 
  lake, 
  which 
  has 
  a 
  length 
  

   cf 
  about 
  one 
  and 
  a 
  half 
  miles 
  and 
  a 
  maximum 
  depth 
  of 
  18 
  feet. 
  

  

  This 
  lake 
  or 
  pool 
  is 
  situated 
  in 
  the 
  lands 
  of 
  the 
  village 
  of 
  Lenkra, 
  

   where 
  the 
  stream 
  runs 
  through 
  a 
  patch 
  of 
  soft 
  tertiary 
  shales 
  and 
  

   sandstones, 
  and 
  the 
  valley 
  is 
  consequently 
  more 
  open 
  and 
  the 
  

   gradient 
  lower 
  than 
  at 
  Dobukhol. 
  So 
  far 
  as 
  can 
  be 
  judged 
  from 
  the 
  

   present 
  aspect 
  of 
  the 
  pool, 
  and 
  from 
  the 
  character 
  of 
  the 
  stream 
  bed 
  

   above 
  and 
  below 
  it, 
  the 
  stream 
  flowed 
  through 
  an 
  old 
  alluvial 
  plain 
  

   of 
  fine 
  grained 
  muddy 
  silt, 
  on 
  a 
  sandy 
  bottom 
  in 
  a 
  narrow, 
  steep 
  

   sided 
  channel 
  of 
  some 
  15 
  to 
  18 
  feet 
  in 
  depth. 
  The 
  gradient 
  must 
  

   have 
  been 
  small, 
  but 
  the 
  average 
  must 
  have 
  been 
  increased 
  above 
  

   that 
  of 
  the 
  sandy 
  stretches 
  by 
  occasional 
  barriers 
  of 
  rock. 
  

  

  Travelling 
  up 
  this 
  pool 
  from 
  the 
  lower 
  end, 
  the 
  banks 
  remain 
  

   high 
  for 
  the 
  first 
  quarter 
  of 
  a 
  mile, 
  and 
  the 
  signs 
  of 
  submergence 
  

   are 
  not 
  very 
  noticeable. 
  About 
  three 
  furlongs 
  from 
  the 
  lower 
  end 
  

   there 
  is 
  a 
  depth 
  of 
  9 
  feet 
  of 
  water, 
  where 
  a 
  footpath 
  used 
  to 
  cross 
  

   the 
  stream 
  and 
  the 
  normal 
  depth 
  was 
  less 
  than 
  a 
  foot. 
  Here 
  dead 
  

   bamboo 
  clumps 
  begin 
  to 
  be 
  conspicuous. 
  Half 
  a 
  mile 
  from 
  the 
  lower 
  

   end 
  the 
  high 
  banks 
  have 
  sunk 
  beneath 
  the 
  water 
  and 
  the 
  pool 
  

   spreads 
  out 
  over 
  the 
  surface 
  of 
  the 
  alluvial 
  plain, 
  the 
  outer 
  margin 
  

   being 
  indefinite, 
  while 
  the 
  channel 
  is 
  bordered 
  on 
  both 
  sides 
  by 
  a 
  

   tangle 
  of 
  dead 
  and 
  bleached 
  bamboo 
  stems 
  and 
  tree 
  trunks. 
  This 
  

   continues 
  for 
  about 
  half 
  a 
  mile, 
  the 
  margins 
  of 
  the 
  pool 
  then 
  become
