﻿THE 
  EPICENTRAL 
  TRACT.

  As 
  the 
  water 
  in 
  the 
  pool 
  deepened, 
  the 
  lower 
  line 
  of 
  vegetation 
  

   on 
  the 
  banks, 
  marking 
  normal 
  high 
  water 
  level, 
  descended 
  to 
  the 
  

   water's 
  edge, 
  and 
  then 
  trees 
  were 
  seen 
  standing 
  in 
  the 
  water 
  and 
  

   killed 
  by 
  the 
  submergence 
  of 
  their 
  roots. 
  About 
  200 
  yards 
  from 
  

   the 
  lower 
  end 
  the 
  stream 
  bed 
  takes 
  a 
  bend, 
  and 
  here 
  the 
  greatest 
  

   depth 
  of 
  water 
  was 
  found 
  to 
  be 
  12 
  feet. 
  On 
  the 
  inner 
  or 
  concave 
  side 
  

   of 
  the 
  bend 
  was 
  a 
  gently 
  sloping 
  terrace 
  of 
  stream 
  gravels, 
  which 
  

   had 
  been 
  partially 
  submerged, 
  and 
  a 
  number 
  of 
  trees 
  and 
  bamboo 
  

   clumps 
  had 
  been 
  killed, 
  their 
  dead 
  stems 
  standing 
  up 
  out 
  of 
  the 
  water 
  

   and 
  proving 
  the 
  recency 
  of 
  their 
  submergence. 
  Here 
  the 
  track 
  

   from 
  Darangiri 
  crosses 
  the 
  stream 
  and 
  affords 
  independent 
  evi- 
  

   dence 
  of 
  submergence, 
  for 
  though 
  there 
  was 
  not 
  ordinarily 
  a 
  greater 
  

   depth 
  than 
  a 
  foot 
  before 
  the 
  earthquake 
  this 
  is 
  now 
  the 
  deepest 
  

   part 
  of 
  the 
  pool. 
  

  

  About 
  200 
  yards 
  above 
  the 
  deepest 
  point, 
  the 
  stream 
  once 
  

   more 
  resumes 
  its 
  normal 
  character, 
  and 
  as 
  the 
  water 
  shallows 
  

   towards 
  the 
  upper 
  end, 
  the 
  bottom 
  can 
  be 
  seen 
  covered 
  with 
  

   boulders. 
  At 
  the 
  head 
  of 
  the 
  pool 
  is 
  a 
  small 
  deltaic 
  deposit 
  of 
  

   boulders, 
  due 
  to 
  the 
  checking 
  of 
  the 
  current 
  as 
  it 
  entered 
  the 
  pool. 
  

   That 
  there 
  is 
  not 
  a 
  larger 
  delta 
  is 
  due 
  to 
  the 
  other 
  pools, 
  to 
  be 
  

   referred 
  to 
  presently, 
  higher 
  up 
  the 
  stream, 
  by 
  which 
  most 
  of 
  its 
  

   burden 
  was 
  intercepted. 
  

  

  From 
  the 
  gradual 
  increase 
  in 
  depth 
  at 
  either 
  end 
  it 
  is 
  evident 
  

   that 
  this 
  pool 
  is 
  due 
  to 
  a 
  bending 
  of 
  the 
  river 
  bed 
  exactly 
  similar 
  

   to 
  that 
  which 
  gave 
  rise 
  to 
  the 
  two 
  large 
  pools 
  on 
  the 
  east 
  side 
  of 
  

   the 
  Chedrang 
  fault. 
  In 
  this 
  case 
  no 
  fault 
  was 
  seen, 
  and 
  I 
  do 
  not 
  

   think 
  that, 
  had 
  there 
  been 
  one 
  on 
  large 
  enough 
  a 
  scale 
  to 
  account 
  

   for 
  this 
  lake, 
  it 
  could 
  have 
  escaped 
  notice. 
  As 
  regards 
  the 
  

   amount 
  of 
  the 
  bending 
  that 
  has 
  taken 
  place, 
  the 
  depth 
  of 
  the 
  

   pool 
  shows 
  that 
  the 
  stream 
  bed 
  has 
  been 
  depressed 
  at 
  least 
  12 
  feet 
  

   below 
  the 
  outlet 
  of 
  the 
  pool 
  ; 
  there 
  has 
  consequently 
  been 
  at 
  least 
  

   that 
  amount 
  of 
  differential 
  movement 
  in 
  a 
  vertical 
  direction. 
  But 
  

   the 
  stream 
  bed 
  was 
  not 
  originally 
  level; 
  to 
  judge 
  from 
  its 
  nature,
