THE KURRAJONG EARTHQUAKE. 99 



Report H. T. J. Dawson of Tar alga. 



Sound of window rattling, wood ceilings cracking. In a 

 two-story shop a man heard rattle of crockery upstairs and 

 ran up thinking that some intruder was there. In my own 

 place one of the children put up a window and said, "That's 

 funny ! I heard thunder and there are no clouds.'' 



Report of W. W. Filmer of Toronto. 



" Extract from my note book made about fif ceen minutes 

 after the shock. " Time 8*27 p.m. Sounds like three large 

 explosions. Second explosion about half a second after the 

 first, and third about one-fifth second after second. Then 

 a rumbling sound which as it got louder appeared to be 

 due to something having struck a number of telegraph lines. 

 This sound continued for about ten seconds. Then a sound 

 on the roof like that which would be made by a huge soft 

 rubber ball bouncing from one end of the roof to the other 

 end, from the N.W. end to the S.E. end (the roof is 40 feet 

 long), the roof is of iron, and the sound lasted probably a 

 little more than one second. During the time of the roof 

 sounds the bed vibrated up and down (I was in bed at the 

 time). This alarmed my wife. I mentioned this to show 

 how conspicuous the vibrations were. My son who was 

 also in bed noted the bed vibrations in his room. Total 

 time of shock about twelve seconds. Sound appeared to 

 come from the air ; this was probably due to the roof 

 vibrations. Immediately after the shock I ran to my 

 laboratory to see if a delicate pendulum one metre long 

 was vibrating. It was perfectly still. The vibrations 

 appeared to come from the N.W. or a little to the W. of 

 that point." 



Report of H. Schomberg of Greta. 



"We first felt the shock about 8*25 p.m. It was heralded 

 by a sort of explosion similar to what one would hear during 

 blasting operations. Then the windows in the room began
