﻿FISSURES

  All 
  these 
  causes 
  combined 
  would 
  cause 
  the 
  land 
  immediately 
  on 
  

   either 
  side 
  of 
  the 
  river 
  channels 
  to 
  subside 
  more 
  than 
  elsewhere, 
  and 
  

   so 
  the 
  relative 
  greater 
  elevation 
  of 
  the 
  river 
  banks 
  would 
  disappear. 
  

   In 
  fact, 
  the 
  general_effect 
  of 
  the 
  earthquake 
  throughout 
  the 
  districts 
  

   where 
  vents 
  and 
  fissures 
  were 
  formed, 
  may 
  be 
  described 
  as 
  tending 
  

   to 
  reduce 
  inequalities 
  of 
  level 
  by 
  causing 
  a 
  depression 
  of 
  the 
  high 
  

   ground 
  and 
  an 
  elevation 
  of 
  the 
  low. 
  

  

  A 
  very 
  remarkable 
  result 
  of 
  the 
  earthquake 
  was 
  the 
  sudden 
  rise 
  

   of 
  the 
  rivers 
  which 
  accompanied 
  it 
  over 
  a 
  large 
  area. 
  I 
  do 
  not 
  here 
  

   refer 
  to 
  the 
  extensive 
  floods 
  which 
  were 
  experienced 
  later 
  on 
  and 
  

   were 
  indirectly 
  the 
  result 
  of 
  the 
  earthquake, 
  but 
  to 
  a 
  sudden 
  

   and 
  immediate 
  rise, 
  varying 
  from 
  two 
  to 
  ten 
  feet, 
  which 
  was 
  observed 
  

   immediately 
  after 
  the 
  earthquake 
  and 
  passed 
  off 
  in 
  the 
  course 
  of 
  the 
  

   next 
  day 
  or 
  two. 
  

  

  At 
  Gauhati 
  the 
  river 
  gauge, 
  which 
  is 
  fixed 
  on 
  a 
  hill 
  of 
  gneiss, 
  

   showed 
  a 
  height 
  of 
  167*41 
  ft. 
  above 
  sea 
  level 
  at 
  7 
  A.M. 
  on 
  the 
  morning 
  

   of 
  the 
  1 
  2th 
  June; 
  at 
  6 
  P.M., 
  about 
  three 
  quarters 
  of 
  an 
  hour 
  after 
  the 
  

   earthquake, 
  the 
  water 
  stood 
  at 
  175*00, 
  showing 
  a 
  rise 
  of 
  7*59 
  ft 
  ; 
  the 
  

   next 
  morning 
  it 
  had 
  sunk 
  to 
  173*11, 
  at 
  7 
  A.M. 
  on 
  14th 
  to 
  169*96 
  and 
  at 
  

   7 
  A.M.' 
  on 
  15th 
  to 
  167*91, 
  having 
  thus 
  recovered 
  its 
  normal 
  level 
  in 
  

   two 
  and 
  a 
  half 
  days. 
  

  

  At 
  Goalpara 
  the 
  Brahmaputra 
  river 
  is 
  said 
  to 
  have 
  invaded 
  the 
  

   station 
  in 
  the 
  form 
  of 
  a 
  wave 
  10 
  feet 
  high 
  and 
  remained 
  at 
  8 
  feet 
  

   above 
  its 
  previous 
  level 
  after 
  -the 
  earthquake 
  had 
  passed 
  ; 
  at 
  Kaunia, 
  

   the^Dharla 
  river 
  is 
  reported 
  to 
  have 
  risen 
  3 
  feet 
  immediately 
  after 
  

   the 
  earthquake. 
  At 
  Maimansingh 
  the 
  Brahmaputra 
  river 
  rose 
  4 
  feet 
  

   and 
  at 
  Jamalpur 
  5 
  to 
  6 
  feet. 
  In 
  the 
  Bogra 
  district 
  it 
  is 
  reported 
  that 
  

   the 
  rivers 
  all 
  rose 
  from 
  1 
  to 
  4 
  feet 
  and 
  that 
  they 
  all 
  fell 
  again 
  within 
  

   the 
  course 
  of 
  the 
  next 
  three 
  or 
  four 
  days; 
  and 
  so 
  on. 
  Many 
  more 
  

   reports 
  could 
  be 
  quoted, 
  but 
  sufficient 
  has 
  been 
  done 
  to 
  show 
  that 
  

   the 
  phenomenon 
  was 
  a 
  general, 
  not 
  an 
  isolated, 
  one. 
  

  

  In 
  part 
  this 
  rise 
  of 
  the 
  rivers 
  may 
  be 
  attributed 
  to 
  the 
  large
