  OLDHAM: 
  GREAT 
  EARTHQUAKE 
  OF 
  '.897. 
  

  

  there 
  were, 
  within 
  the 
  epicentral 
  tract, 
  great 
  movements 
  of 
  permanent 
  displace- 
  

   ment, 
  superadded 
  to 
  the 
  molecular 
  vibratory 
  movement 
  of 
  the 
  more 
  or 
  less 
  purely 
  

   elastic 
  waves 
  set 
  up 
  by 
  the 
  earthquake 
  ; 
  and 
  it 
  is 
  to 
  the 
  former 
  of 
  these, 
  rather 
  

   than 
  to 
  the 
  latter, 
  that 
  high 
  velocities 
  of 
  projection 
  within 
  the 
  epicentral 
  tract 
  

   must 
  be 
  attributed.

  Dei 
  ails 
  of 
  the 
  direction 
  of 
  overthrow 
  and 
  projection 
  of 
  free 
  fall- 
  

   ing 
  objects, 
  and 
  a 
  consideration 
  of 
  the 
  applicability 
  of 
  this 
  form 
  

   of 
  evidence 
  to 
  the 
  determination 
  of 
  the 
  position 
  of 
  the 
  epicentre. 
  

  

  In 
  the 
  following 
  list 
  are 
  given 
  all 
  the 
  cases 
  that 
  have 
  been 
  observed 
  of 
  objects 
  

   projected 
  or 
  overthrown. 
  In 
  the 
  case 
  of 
  objects 
  overthrown 
  by 
  the 
  earthquake 
  

   only 
  those 
  whose 
  direction 
  of 
  fall 
  was 
  not 
  largely 
  controlled 
  by 
  their 
  form 
  have 
  

   been 
  included. 
  Such 
  maybe 
  designated 
  as 
  "free-falling," 
  and 
  are 
  almost 
  exclu- 
  

   sively 
  square 
  or 
  round 
  pillars 
  or 
  pinnacles 
  ; 
  objects 
  having 
  an 
  oblong 
  section 
  with 
  

   one 
  axis 
  much 
  longer 
  than 
  the 
  other 
  have 
  been 
  excluded, 
  as 
  they 
  were 
  not 
  free 
  to 
  

   fall 
  in 
  any[direction, 
  but 
  must 
  necessarily 
  fall 
  more 
  or 
  less 
  at 
  right 
  angles 
  to 
  

   their 
  longer 
  axis.
