﻿THE 
  AFTERSHOCKS.

  was 
  in 
  a 
  constant 
  state 
  of 
  tremor, 
  and 
  at 
  Tura 
  I 
  was 
  informed 
  that 
  a 
  

   hanging 
  lamp 
  was 
  kept 
  constantly 
  on 
  the 
  swing 
  for 
  three 
  or 
  four 
  

   days. 
  Some 
  idea 
  of 
  the 
  frequency 
  of 
  the 
  earthquakes 
  in 
  Shillong 
  

   may 
  be 
  gathered 
  from 
  the 
  fact 
  that 
  a 
  record 
  kept 
  on 
  the 
  night 
  of 
  

   the 
  19th 
  June, 
  seven 
  days 
  after 
  the 
  earthquake 
  showed 
  33 
  distinct 
  

   sensible 
  shocks 
  in 
  4^ 
  hours, 
  or 
  an 
  average 
  of 
  one 
  nearly 
  every 
  8 
  

   minutes. 
  

  

  Besides 
  the 
  innumerable 
  smaller 
  shocks 
  there 
  were 
  many 
  which 
  

   would 
  have 
  attracted 
  considerable 
  attention 
  in 
  any 
  other 
  years, 
  and 
  

   not 
  a 
  few 
  that 
  would 
  have 
  been 
  classed 
  as 
  great 
  earthquakes 
  and 
  

   have 
  become 
  the 
  subject 
  of 
  special 
  investigation. 
  Dwarfed 
  as 
  they 
  

   were, 
  however, 
  by 
  the 
  great 
  one 
  which 
  preceded 
  them 
  they 
  attracted 
  

   comparatively 
  little 
  attention, 
  and 
  it 
  is 
  impossible 
  to 
  get 
  much 
  more 
  

   information 
  about 
  them 
  than 
  a 
  somewhat 
  imperfect 
  record 
  of 
  the 
  

   area 
  over 
  which 
  they 
  were 
  felt. 
  

  

  One 
  of 
  these, 
  occurred 
  at 
  about 
  1-30 
  A.M., 
  local 
  time, 
  of 
  the 
  

   13th 
  June, 
  and 
  another 
  about 
  1 
  1 
  J 
  hours 
  later. 
  Both 
  of 
  these 
  were 
  

   severe 
  enough 
  to 
  have 
  caused 
  great 
  destruction 
  in 
  the 
  central 
  area, 
  

   had 
  there 
  been 
  anything 
  left 
  to 
  destroy, 
  and 
  were 
  felt 
  as 
  far 
  as 
  

   Calcutta 
  — 
  the 
  former 
  even 
  as 
  far 
  as 
  Sutna, 
  on 
  the 
  East 
  Indian 
  Rail- 
  

   way 
  .beyond 
  Allahabad. 
  At 
  10-40 
  P.M., 
  of 
  the 
  13th 
  there 
  was 
  

   another 
  shock 
  of 
  sufficient 
  extent 
  to 
  be 
  felt 
  at 
  Calcutta, 
  and 
  again 
  

   at 
  0-47 
  A.M., 
  on 
  the 
  14th. 
  After 
  this 
  there 
  was 
  a 
  falling 
  off 
  in 
  

   number 
  and 
  violence 
  of 
  the 
  shocks, 
  but 
  on 
  the 
  22nd 
  June, 
  at 
  7-24 
  

   P.M., 
  and 
  29th 
  at 
  10-19 
  P.M., 
  shocks 
  were 
  again 
  felt 
  in 
  Calcutta. 
  

   Towards 
  the 
  beginning 
  of 
  August 
  there 
  was 
  a 
  revival 
  of 
  seismic 
  

   activity, 
  and 
  on 
  the 
  2nd 
  another 
  shock 
  which 
  was 
  felt 
  at 
  Calcutta 
  at 
  

   8-58 
  P.M. 
  One 
  more 
  was 
  felt 
  on 
  9th 
  October 
  at 
  1-40 
  A.M., 
  and 
  since 
  

   then 
  there 
  has 
  been 
  no 
  shock 
  severe 
  and 
  extensive 
  enough 
  to 
  be 
  

   felt 
  at 
  Calcutta. 
  

  

  In 
  the 
  early 
  days 
  following 
  the 
  great 
  shock, 
  the 
  only 
  detailed 
  

   records 
  I 
  have 
  been 
  able 
  to 
  obtain 
  refer 
  to 
  earthquakes 
  of 
  considerable 
  

   severity 
  and 
  covering 
  a 
  considerable 
  area, 
  but 
  as 
  more 
  complete
