Remarks. 



In the early morning a severe shock for i\ or 2 m. 



N. N. W. 



N. W. Distinct sound for a few seconds before 



shock. There were some feeble tremors for 



some 30 s. afterwards. 



Premonitory sound plainly heard from W or 



W. S. W. 

 Premonitory sound very plain for some 5 s. 



before the shock. 



(No shocks felt.) 



Surarim. 



Sound very plain before, during'and after the 

 shock appeared to have ceased. I was in 

 Surarim (eight miles from Cherrapunji on the 

 Cherra-Shillong cart road) when I felt this 

 shock. The character of the sound reminded 

 me strongly of the sound as heard in 

 Maophlang. 



Sound very plain. 



Sound heard 10 or 15 s. before the shock was felt* 



No sound. 



Cherrapunji. 



Sound plain for 10 or 20 s. before the shock. 

 The found accompanying this last shock was 

 loud, but it differed in character from the 

 sound heard in Maophlang and Surarim. At 

 those places it is more awe-inspiring, and 

 partakes more of the character of the sounds I 

 heard at Shillong, June 12th. The best way 

 I can describe the difference is by saying (using 

 a term common in medicine) that at those 

 places it is more amphoric). 



No sound. This was made up of two long shocks 

 with a lull for about ( ? ) 2 s. between them. 



Slight sound.
